Rain plays a key role in the hydrologic, or water, cycle in which moisture from the oceans evaporates, condenses into clouds, precipitates back to earth, and eventually returns to the ocean via runoff into streams and rivers to begin the cycle again. Formation of RaindropsClouds contain huge numbers of tiny droplets of moisture. Raindrops are formed when these tiny droplets are enlarged, first by moisture from the surrounding air condensing on them and then by coalescing with other droplets during their descent. Raindrops vary in size from about 0.02 in. (0.5 mm) to as much as 0.33 in. (8 mm) in thunderstorms. From the time they leave the bottom of the cloud, evaporation takes place and, if the cloud is high, the air warm and dry, and the raindrops small, so that they fall slowly, they may evaporate completely before they reach the earth. If they do so, the drops are called virga..

云计算市场的许多小规模提供商的云计算服务和产品在速度、成本、灵活性，甚至在本地部署和混合云选项方面都会对全球云计算行业巨头构成挑战。 云计算平台的规模一定很大，对吧?如果云计算的最佳功能是用户只需点击几秒钟并启动一台机器，那么必然需要建设和运营部署大量服务器的大量数据中心。 不过，“大”这个词是相对的。规模最大的云计算行业巨头AWS、Microsoft Azure、谷歌云可能会占据大部分市场份额，但它们并不能阻碍云计算市场其他提供商的发展。一些规模较小的云计算提供商正在开发利基市场，并采用其他的竞争方式，然而与云计算行业巨头相比，他们的服务器数量确实微不足道。 人们普遍发现，这些“微不足道”的云计算提供商也在全球范围内运营着数十个数据中心，而这些数据中心也拥有足够数量的服务器，只是没有云计算巨头那么多。 事实证明，对于开发人员来说，规模并不总是最具吸引力的选择。机器实例几乎是运行在普通操作系统的普通硬件，软件可以迁移以寻找更好的选择。云计算公司在用户界面、复杂功能、速度等方面展开了竞争，有时甚至在规模、价格等看似明显的优势方面的云计算巨头也面临一些竞争。 微服务架构的发展正在孕育更广泛的云计算市场。将工作负载分成N个不同部分的开发人员不需要将自己限制在一个云平台中。当连续的数据包流正在传输时，保持软件在同一数据中心运行是有意义的，但通常可能会将应用程序分解为许多松散链接的代码块，偶尔交换消息，并且不需要最快的响应速度。如果有充分的理由，后台处理和分析功能很容易转移到不同的云平台。如果企业在为系统创建体系结构时非常谨慎，甚至可以将每个微服务放在不同的云平台上。 所有这一切都意味着云计算之战并不局限于规模最大化。以下是十几个规模较小的云计算提供商，他们的云计算产品和服务也有自己独特的优势，它们都很吸引人，但并不是客户唯一的选择。当他们超越规模最大的竞争对手时，人们发现云计算市场是一个令人惊讶的巨大和多样化的市场。 1.Wasabi公司 2.Vultr公司 云计算提供商Vultr公司通过以每小时2.50美元的价格提供最低价格的实例，按小时计费。这台机器只配备512KB的内存，适用于静态Web服务器，但用户可以花费更多的费用购买更大的机器实例。 该公司已经扩展了其产品线，其中包括裸机服务器，这些服务器没有虚拟化层的阻碍。还有专门的服务器，可以减少与攻击者共享同一个服务器的威胁。Vultr公司在全球运营16个数据中心。其云平台的界面很灵活，但是提供的服务有限并且比较基础，可能提供的仅仅是命令行。如果用户希望服务器在引导时运行脚本，则可以使用一个很好的输入字段来键入脚本。但以每月2.50美元的价格计算，要求过高将是错误的。 3.UpCloud公司 UpCloud公司的亮点是提供持久硬盘存储服务，该公司称，它提供比SSD硬盘更快的性能。在启动和持续性能方面甚至可能快50%。用户必须测试其应用程序才能确定，因为速度将根据计算和数据获取的混合而变化。 UpCloud的许多其他部分也令人熟悉。UpCloud在全球运行API、一系列标准模板和数据中心，其中两个位于赫尔辛基的UpCloud公司总部附近。UpCloud提供公共云托管、私有选项和一些软件层来创建组合。软件定义的网络很快就会到来。 其基本实例提供1GB内存和25GB硬盘存储空间，起价为5美元，并以与竞争对手大致相同的方式向上扩展。UpCloud并不一定能提供更低的价格，但提供更快的磁盘访问。 4.Packet公司 Packet可能规模相对较小，但它提供功能齐全的专门服务器，它们以“裸机”运行客户的应用程序。这意味着客户的I/O和存储操作不会因无限的虚拟化层而陷入困境(至少在客户通过过度的容器化添加自己的虚拟化层之前，这是客户的责任)。 客户需要为采用Packet的机器支付更多费用，但其获得回报更多。c1.large.arm机器配备128GB的内存和32个核心处理器，其价格是每小时1美元，在一个月内累计超过672小时。Packet还采用一些配置较低的服务器，配备8 GB内存和4个核心处理器，每小时只需7美分。 其具备的一个很好的特性是现货定价市场，客户可以在那里出价购买硬件。一些需求放缓时的价格似乎比清单上的价格便宜50%以上。Packet在全球运营18个数据中心，还提供RESTful API，以及使用企业的配置、安全和管理软件的本地版本构建混合云的大量选项。 5.Linode公司 另一家提供小型灵活的Linux机器root访问权限的云计算提供商是Linode公司，其价格每月低至5美元。Linode公司支持全球9个数据中心的10个主要Linux发行版，其运营的第10个数据中心在印度孟买。 如果客户需要安装特定服务，Linode公司的用户社区将共享大量启动脚本，这些脚本将安装正确的软件并自定义配置。这些脚本涵盖了大多数主要应用程序，如WordPress、Plesk、代理服务器、OpenVPN和LAMP堆栈。客户还可以创建自己构建的脚本。 6.Hidora公司 如果客户使用一些标准模型(NoDE.JS、PHP、Java)部署Web应用程序，Hidora公司提供一个PaaS(平台即服务)来适应。该公司认为，其灵活的扩展以更好的价格提供了更好的性能。可以将负载平衡、备份和空闲出站带宽等服务整合到捆绑包中。 Hidora是如何扩展和更新旧的共享托管模型以支持现代微服务架构的一个很好的例子。如果客户想要获得root访问权限，Hidora公司会提供虚拟专用服务器，但客户也可以将Docker容器部署到其Kubernetes集群。 Hidora将其服务器部署在瑞士，并确保它们受到瑞士数据保护法的保护。 7.DigitalOcean公司 DigitalOcean之所以受到开发人员的欢迎，是因为它简化了虚拟机的启动、大小调整和拆除虚拟机的过程，DigitalOcean称之为“Droplets”。在取得一些成功之后，该公司最近扩展了PostgreSQL数据库的更多托管服务、数据桶和Kubernetes集群。Droplet按小时计费，但当月计费的小时数上限为672小时，即四周的小时数，因此每个月的价格都相同。该公司将其价格设置为5美元的倍数，使账单计算更加简单。DigitalOcean公司在全球8个城市拥有并运营12个数据中心。 8.Shared hosting公司 Shared hosting的云服务由共享Web服务器提供。客户在LAMP服务器上租借了一个帐户，上传了其HTML、JavaScript/HP，并按月支付费用，虽然不会给客户提供root权限，但有时会让客户使用Telnet。 许多专门提供这些服务的公司(IONOS、A2、BlueHost、HostGator、InMotion)已经逐渐扩展到云服务器业务，提供虚拟专用服务器和专用服务器。其计费通常按月计算，时间长达三年。 Shared hosting公司似乎对每隔几个小时启动和拆除机器以满足需求飙升的客户感兴趣。尽管如此，它们仍然是一个灵活的选项，可用于小型专用项目。 9.Antsle公司 Antsle公司可能是规模最小的云计算提供商。Antsle公司提供了一款无风扇服务器，可以放在桌面上，通过客户自己的“云托管”仪表板创建Gentoo Linux实例。这个服务器小而安静，提供云计算的大部分灵活性和功能。其CPU功率取决于客户购买的产品，客户可以通过控制物理安全性和保持一切可见性来运行工作负载，从而获得更大的工作量。 Antsle公司还正在为其支持其他硬件的软件版本进行封闭测试。或者客户也可以在裸机服务器Antsle主机中使用相同的界面和软件。

单细胞RNA测序是目前的一大热门。通过单细胞RNA测序，能够带给我们原来 bulk RNA （群体RNA）测序所得不到的信息，对于研究发育生物学、肿瘤生物学、免疫等有着极其重要的价值。单细胞测序的核心就是T-sne降维，以及聚类。那么在做这些工作之前的质控，会影响到整个分析的成败。这篇文章我就来给大家讲讲单细胞质控的那些事儿。 首先，我们介绍转录表达中的一个现象：transcriptional bursting。什么叫做trancriptional bursting? 如下图： 我们都知道，基因的转录和表达是有周期性的。当基因的转录被激活时，mRNA的水平会突然上升，然后慢慢下降，而相应的蛋白水平的变化会有一定的滞后。 这种周期的频率，以及每次波动的大小，在RNA分析中都会影响最终的表达量（可以是FPKM值、RPKM值）。这种周期性的转录现象，就是同transcriptional bursting有关。 我们在分析RNA表达量的时候，会发现这样一个现象，很多重要转录调控因子的FPKM值往往比较低。推测可能他们只在某一特定的时间段在特定的细胞中表达。 最终，我们拿到的结果可能就与实际情况出入很大，如下图所示。 我们来看看单细胞实验的整体流程如下图，分析一下哪些环节会带来偏好性，以及如何发现和质控 。 我们在做单细胞测序的时候，首先要做细胞分离。细胞分离必须要在短时间内完成，否则会影响到细胞的状态，甚至可能导致RNA从细胞中漏出。 从组织中分离出细胞往往很困难，具体方法可以参考《Tissue Handling and Dissociation for Single-Cell RNA-Seq》这本书。这里总结一下从组织中分离出单细胞可能遇到的问题： 在a图和b图中，一些高表达的基因被证明是由细胞分离的操作引起的。(van den Brink et al. Nature methods 2017)。 在细胞分离的过程中可能存在着污染。如图所示，在day3的样本中都存在着Neutrophil细胞的marker基因的表达。这有可能就是样本中存在着RNA的污染。 解决的方法就是利用空的droplets 来估计背景信号，利用软件SoupX来移除背景噪音（Young MD, BiorXiv 2018）。 我们在做细胞分选的过程中还会遇到如下的问题： 对于不同的单细胞测序的策略总结如下。因此，对于自己研究的组织应该采用什么样的单细胞策略，需要十分慎重。 另外，细胞质量比较差、亦或有很多死细胞或者细胞碎片的话，也会造成有很多droplet中存在多个细胞。如下图所示：有三个冻存样本有很高比列的droplet存在多个细胞。 在实际进行数据分析的过程中，这些droplet有可能会被单独聚为一类，也有可能会富集在两个细胞群的中间区域。 我们通过如下情况来判断是否存在douplet(含有多个细胞的液滴): 目前，有一系列的软件可以帮助我们筛选到doublet，例如： 检测doublet的软件算法都非常类似，基本的原理非常简单，有下面几个步骤： 在做单细胞测序的之前，需要对细胞进行裂解。不同的细胞组织，裂解条件也会不一样。如果裂解条件过于严格，就会影响文库制备。 构建文库同时加入浓度已知的spike-in，其中包括： Spike-ins 的用途 1.去除技术噪音 2.检测捕获效率 3.计算RNA的起始量 4.数据的normalization Spike-ins的问题 1.Spike-ins与内源基因还是有区别的，如在扩增偏好性方面 2.一般不用于drop-seq sample Multiplexing（请参考以下网址） 很多时候并不好用。每个细胞的total reads依旧会有很大的区别。 https://emea.illumina.com/science/technology/next-generation-sequencing/plan-experiments/multiplex-sequencing.html 测序过程也有可能受到很多因素的影响： 1.文库复杂性太低，容易形成primer dimer 2.污染问题，请参考： https://www.illumina.com/science/education/minimizing-index-hopping.html ) 本次的分享就到这里，相信大家对整体的实验有了一定了解。下一篇我们继续讲解质控方面的细节。

When you eat a fatty food, it moves through thestomach andon to the intestines. 当你食用富含高脂肪的食物时，脂肪通过胃流入肠道。 In the intestines, a number of processes occur totransfer fat from the foodto special fat cells in yourbody. 在肠道中，脂肪经过一系列的消化流程从食物转化为体内的特殊脂肪细胞。 First, the gall bladder produces bile that breaks thefood"s fat droplets into smaller droplets. 首先，胆囊分泌胆汁分解食物脂肪滴，使其更小。 Next,the pancreas secretes enzymes that attack the fat droplets and break them down into twoparts:fatty acids and glycerol. 然后，胰腺分泌胰腺酶作用于脂肪滴，将其分解为两个部分：脂肪酸和甘油。 This happens because fat droplets are too big to pass through cell membranes. 这是因为脂肪滴过大，无法穿过细胞膜。 The broken downfat is absorbed by the cells lining the intestine, where it is reassembled intofat molecules andeventually shuttled into the bloodstream with the help of lipoproteinparticles. 分解的脂肪被肠粘膜细胞吸收，重组成脂肪细胞，最后负载在脂蛋白颗粒上进入血液循环。 For the most part fat is stored in the fat cells that compose fatty tissue. 大部分的脂肪储存在脂肪细胞内，形成脂肪组织。 Think of a fat cell as a tinyplastic bag filled with a drop of fat. 脂肪细胞好比一个容纳脂肪滴的塑料袋。 Interestingly, fat cells do not multiply. 有趣的是，脂肪细胞并不会变多。 The body contains a finitenumber of fat cells that expand as they absorb fat

The falling waterdrop stands for free fall. The still moment embodies the charm of physics. The digit 3 represents all the members of our class. We are all included in the waterdrop just like we are all integrated into the class.

一)汉语中有一类词叫做量词，位于数词和名词之间，是用以表示事物单位的词。 　 汉语量词分为两类：表人或事物的量词叫物量词；表动作或行为的量词叫动量词。 1．物量词汉语物量词可分为三类： (1)表度量衡的单位，如“尺、里、吨”等。 (2)一般量词，如“个、只、本、间”等。 　 (3)以事物特征、状态来衡量的量词，如“头、口、杯、发、条” 等。 2.动量词汉语的动量词可分为两类： (1)专用动量词，如“次、遍、番、阵、顿”等。 　 (2)借用动量词，一般借用与动作有关的名词，如“刀”(砍一刀)，“笔”(写一笔)，“星期”(讨论一星期)等。 　 汉语量词一般要与数词一起使用，合称数量结构，如： 　 三斤肉，一头牛，一杯咖啡，一山树，一屋人，一架书，五匹布， 　 两桶水，一块煤，一粒米，一剂药，两行树，一朵花，一线希望， 四排房子，三堆鸡蛋 　 汉语偶尔也有不用量词的，这不过在古汉语中出现。如： 　 卧室里是一桌一凳一床，床板只有两块。(《朝花夕拾.琐记》) 　 撤屏视之，一人，一桌，一椅，一扇，一抚尺而已。(《口技》) 在一些成语中，常有不用量词的。如：" 　 千言万语，九牛一毛，三人一组，七上八下，三头六臂，一心一意，三言两语，七嘴八舌，一草一木，一砖一瓦. 　 还有表示行政区域划分的名词，如三省，五市，两县。这大概是沿袭旧时四言词组所演变成的，或受到古汉语的影响。 　 (二)英语没有量词。数词(或不定冠词)可直接置于数名词之前表示数量。如： a(ones)book 一本书 three Workers 三个工人 four rifles 四枝枪 six cars 六辆汽车 five tractors 五部拖拉机 seven lathes 七台车床 eight lamps 八盏灯 ten houses 十栋房屋 　 但是，在一定的条件下，由于意义上的要求，英语中的可数名 词也可与特殊表示量的概念名词连用。这种特殊量词，通常是借用了普通名词，具有独立词汇意义。不过在量词和名词之间要有一个介词“of”。如： a packet of cigarettes 一包纸烟 a company of soldiers 一连士兵 two groups of children 两群小孩 a team of horses 一队马 three heaps of eggs 三堆鸡蛋 four blocks of houses 四排房子 　　为了方便起见，这里暂且把英语“名词+of+名词”这一形式称为英语特殊“量词”。这种特殊量词，常借用普通名词，具有独立词汇意义。英语这类“量词”也可以分成三类： 1.以事物特征、状态来衡量的“量词”，如： a bar of chocolate 一条巧克力 a blanket of snow 一片白雪 a blast of wind 一阵风 a cake of soap 一块肥皂 a coat of paint 一层油漆 a cut of pork 一块肉 a drop of water 一滴水 a speck of dust 一粒灰尘 a sheet of skin 一张皮 2.用以表示抽象名词数量单位的“量词”，如： an article of food 一种食品 an Item of news 一则消息 a period of time 一段时间 a bout of fighting 一场战斗 a chain of thought 一连串想法 a flash of hope 一线希望 a round of applause 一阵掌声 a scene of great rejoicing 一片欢腾 a shower of criticism 一阵批评 a wisp of smoke 一缕轻烟 a peal of thunder 一阵雷声 a gleam a ray of hope 一线希望 a plot of land 一小块地 3．用以表示一群、群体或集合概念的量词，如： an army of workers 一大队工人 a batch of new cadres 一批新干部 a body of people 一大组人 a circle of friends 一群朋友 a galaxy of talents 一大批英才 a file of soldiers 一列士兵 a troop of scouts 一队童子军 a mob of gangsters 一伙歹徒 　 上面是有关人群方面的集体量词。下面举一些其他方面的集 　　体量词，这些“量词”的用法，都带有生动的修辞色彩。如： a bouquet of flowers 一束花 a bunch of grapes 一串葡萄 a night of doves 一群鸽子 a cluster of bees 一群蜜蜂 a little of kittens 一窝小猫 a mountain of books 一大堆书 a Series of articles 一系列文章 a sea of flags 一片旗海 a Set of tools 一套工具 a spate of jokes 一串笑语 (三)在汉英“量词”互译时必须注意： 　 1．词的搭配不同，如“群”字是最活跃的汉语量词之一，表示“聚在一起的人或物”。在下列汉语词组里，都用“群”字，但在译成英语词组时，却用不同的字。如： (1)一群人 a crowd of people 一群观众 a crowd of spectators (2)一群女学生 a group of girl students 一群旁观者 a group of onlookers (3)一群才子 a galaxy of talents 一群美女 a galaxy of beauties (4)一群欢迎者 a troop of welcomers 一群示威者 a troop of demonstrators (5)一群影迷 a throng of film fans 一群人 a throng of people (6)一群匪徒 a band of gangsters 一群劫匪 a gang of robbers (7)一群羊 a flock of sheep 一群鸭 a flock of ducks (8)一群牛 a herd of cattle． 一群马 a herd of horses (9)一群豺狼 a pack of wolves 一群猎犬 a pack of hounds (1o)一群建筑物 a cluster of buildings 一群海岛 a cluster of islands 　 为什么汉语的量词“群”,会翻译成那么多不同的英语单词呢?因为“群”字在汉语中是没有修辞色彩的，而在英语中，“群” 这个概念却是具有修辞色彩的。如：“crowd”通常指“无组织和无秩序的人群”；“group”通常指“有一定组织的”；“galaxy"常用于比喻“出色或著名的人物群”；“troop”常指“正常行进中的群”;“throng”却指“为数众多的挤在一处或向前涌去的群”;“band”有明显的轻蔑色彩，通指强盗、匪徒等的群(帮、伙)；“flock”通常指飞鸟家禽、牲畜的群，尤指羊群；“herd”通常指大动物的群；“pack”主要指野兽、猎犬等的群；“cluster”指集结物体的群(簇、堆)。(类似的还有swarm，如a swarm of bees等。) 　 反过来说，英语中piece是最活跃的一个“量词”，使用很广，可与许多不可数名词连用，但它没有什么修辞色彩。但翻译成汉语时却产生修辞色彩，在不同的词组里用不同的汉语量词。 a piece of wood 一块木头 a piece of paper 一张纸 a piece of coal 一块煤 a piece of clothing 一件衣服 a piece of furniture 一件家具 a piece of news 一条新闻 a piece of advice 一项忠告 a piece of information 一则消息 a piece of poetry 一首诗 a piece of music 一支乐曲 a piece of prose 一篇散文 a piece of good luck 一回好运气 a piece of kindness 一番好意 a piece of folly 一桩蠢事 a piece of chalk 一枝粉笔 2．英语的“量词”还可以有复数形式，如: drops of tears 泪珠 two groups of children 两群小孩 streams of people 川流不息的人 multitudes of islands 大群大群的岛屿 myriads of stars 无数的星星 　 3．许多英语“量词”可以有其修饰的成分；如：an increasing number of students，不断增加的学生；a rising flow of foreign visitors越来越多的外国来客；a large gathering of people，一大群人。 　 但是，英语中常常有这样的情况，从结构上看有些形容词(或具有形容词作用的词)是修饰“量词”的，可是从含义上看却是修饰后面的名词，如： a new generation 0f people一代新人 a：stagnant pool 0f water 一潭死水 a mere scrap of paper 一纸空文 a rich assortment of goods一批各式各样的货物 a new round of talks 一轮新的会谈。 a thin coat of ice 一层薄冰 　 翻译这类结构时，注意英汉词序的调整，切不可硬套。 　 4．英语“名词+of+名词”这一形式，可以表示同位、所有、修饰等关系。所以翻译时必须注意英汉词序，以免误解。如： (1)表示同位关系 　 all of them他们大家，four of us我们四个，the city of Beijing北京城 在这些词组里，of可以不译。 (2)表示所有的 　 in the centre(heart)of Beijing在北京的中心，from the north of China从中国的北方 (3)表示修饰的 　 a young man of deep reflection深思熟虑的青年，a man of uncertain temper喜怒无常的人 (4)表示组成的 　　a lot of trouble许多麻烦，a cup of tea一杯茶，a drop of water一滴水 　 但是，droplets of water(小水滴)讲的并不是水的量，而是水的模样。这里的of water起修饰droplets的作用。 　 5．英语在表示某些特定的量的时候，使用表量的名词(在汉语是量词)，其组合方式同汉语数量结构一样。如： three dozen pencils 三打铅笔 ten-metre yarn 十公尺的纱线 five-kilogram packs 五公斤包装 　 6．应注意许多名词，从汉语角度看是可数的，在英语中却不可数。例如：news消息，advice忠告，bread面包，furniture家具，在英语中是不可数的。如要表示“一件”、“一个”等概念，要加“a piece of”等这类短语。如： a piece of news 一条新闻 a piece of soap 一块肥皂 　 如要表示“几件”、“几条”等概念时，要加“pieces of”，或者“these articles of”等这类短语。如： two pieces of soap 两块肥皂 these articles of furniture 这几件家具 　 7.在下列词组里，of前后两个名词从语法上分析是同位语。因此，可以分别翻译如下： a red bald of a sun 一轮红日 a great mountain of wave 高山似的波涛 a park of a factory 公园般的工厂 a shell of a man 骨瘦如柴的人 a saint of a man 圣人似的人物 a palace of a house 宫殿似的房屋 a fairyland of a country 仙境似的国土 a whale of a scientist 一位了不起的科学家 　 但of前后的两个名词，不能随意颠倒。如将a park of a factory改为a factory of a park，那就变成了“工厂似的公园”。 　 8．有些英语特殊“量词”，在某种场合译成汉语时不一定要用量词。如： That was a auirk of fate． 那是命运的作弄。 a sea of trouble 恨海无边 I detected a flicker of challenge in his eyes． 我觉察到他的眼神霎时间显出异议。 There was a note of pride in his voice． 他说话的口气带有自豪感。 又如： a store of oil 很多石油 a whale of a difference 天壤之别 a whale of a：story 极妙的故事 have a whale of a goodtime 玩得极愉快 9．动量词中译时，需要借助副词或兼类的名词。 give a punch 打一拳 have a rest 休息一下 have a walk 走一走 fire a shot 放一枪 eat a bite 吃一口 give a kick 踢一脚 Let me have a look． 让我看一看。 For three whole days and nights he did not have a wink of sleep． 他三天三夜没睡一觉。 汉语动量词往往可译为英语同源宾语。如： sleep a sound sleep 睡了一大觉 dream a sweet dream 做了甜蜜的梦 fight a fight 打一仗 smile a smile 笑一笑 laugh a hearty laugh 放声大笑 die a heroic death 英勇牺牲了 　 10.汉语用表示集体的量词时，英语也用相似的集体表量词，但是可数名词应有复数形式。如： 一群猴子 a host of monkeys 一行白鹭 a file of egrets 三盘饺子 three plates of dumplings 一连串问题 a volley of questions 一堆书 a heap of books 　 1l.汉语中有非常丰富的量词，应用广泛。它不仅是一种重要的修辞手段，而且具有十分显著的语法意义。我国古代诗人都喜欢用量词来增加语言的表现力。杜甫的绝句，就是一个突出的例子。 两个黄鹂鸣翠柳，一行白鹭上青天。 窗含西岭千秋雪，门泊东吴万里船。 　 王之涣的诗：“欲穷干旱目，更上一层楼。”也是用量词作对偶的，以增加语言的声色。 　 现代诗人光未然的诗句：“一江离恨、一江愁”(《海边河畔》)，使人感到“离愁”、“别恨”，如滔滔江水那般深，那么多。 　 在现代汉语中量词用得更多了。有人拿六种期刊120页，共6912个字的不同类文章，进行了一次统计，发现其中仅物量词和动量词就用了1228个。在文学作品中比例就更高了。可见，量词在汉语中使用的频率是相当高的，离开了它，我们说话写文章都会有困难。汉语量词用得恰当，会使语言显得更加生动形象。如：“开了一树花”，“飘着一缕轻烟”，“还有一线希望”，“写得一手好字”。 　 但是，汉语量词却是外国学生经常用错的地方。如：“在果园里我们摘了五苹果。”“我们班上一学生病了。”把“我给你一把锄头”说成“我给你一锄头”。又如：把“一只鸟”说成“一条鸟”，把“一张纸”说成“一个纸”。 　 汉语英译也是中国学生感到头痛的问题。很多英语特殊量词富有修辞效果。如：a glimmer of hope，a spatter of rain，a flush of love，an agony of joy等就体现了英语的比喻(metaphor)、拟声(onomatopoeia)、着色(color scheme)、矛盾修饰法(oxymoron)等各种修辞功能。在汉语中，有相当一部分量词，往往必须用几个，十几个乃至几十个不同的英语词来表达。上面举了一个“群”字，现在再举一个“层”字为例。 一层岩石 a layer of rock(指多层中的一层) 一层泥土 a layer of clay(earth) 一层（薄）云 a veil of cloud(指轻纱似的一层) 一层(薄)雾 a veil of mist 一层新油漆 a new coat of paint(指涂层) 一层蜡 a coat of wax 一层油 a film of oil(指薄层) 一层薄塑料膜 a film of plastic 还可以再举一个“阵”字： 一阵笑声 a burst of laughter(指突然发生) 一阵雷声 a burst of thunder 一阵大雨 a flood of rain(强调大量的意思) 一阵眼泪 a flood of tears(指泪如泉涌) a burst of tears(指眼泪夺眶而出) 一阵咳嗽 a spell of coughing(指一段持续) 一阵寒流 a spell of cold Weather 一阵狂怒 a fit of rage(指感情突然发作) 一阵失望 a fit of despair 一阵暴雨 a gust of rain(指猛烈而突然发作) 一阵狂风 a gust of wind 一阵感冒 a bout of influenza(指疾病的发作) 一阵高烧 a bout of high fever 　 从上述例子，可以看出，英汉量词的互译是错综复杂的。因此，不断地探讨英汉互译中如何正确翻译“量词”，是我们在外语教学中应重视的一个问题，也是翻译理论中应重视的一个课题 mark once we translate, God laughs. 好长 王之涣的诗：“欲穷干旱目，更上一层楼。”…… --------------------------------- 欲穷干旱目，更上一层楼。

Clouds are aggregates of water droplets or ice crystal colloids that remain in the atmosphere. Clouds are a tangible result of the enormous water cycle on Earth. When the sun shines on the surface of the earth, water evaporates to form water vapor. Once water vapor is supersaturated, water molecules will gather around the dust (condensation nodules) in the air. The resulting droplets or ice crystals scatter sunlight in all directions, which results in the appearance of clouds.

It looks like a piece of flower sea, flower bud and leaf one to morning and put, think elder sister and younger sister, rush to come into this world. Look, flower bud is five one, like a string of sweet and sweet cherry on the branch. 2、The cherry blossoms are usually five petals, with long stamens in the center, and usually nine to ten flowers, like beautiful yellow bean sprouts. The unborn baby, like a balloon that is about to explode, looks lovely. 3、The mountain cherry and the cherry trees are not as white as peach blossoms, nor as green as pear flowers, they are lilies grey. It is full of red and red, almost the spring of the Beijing city of haitang. In addition, there is also a pale yellow turmeric, a low-hanging branch of the branches, the "spring equinox", the first flowering of the other side, petals to more than 300 pieces of chrysanthemum... The beauty of beauty. 4、The cherry blossoms were so white that they were red, with yellow flowers clustered in five petals. Like plum flower, tree trunk looks like peach tree trunks, leaves of various is spend less, is the green leaves foil flower, blossom but Ye Shaohua, a small branches have seven or eight flower, clusters of clusters, like floating in the blue sky white cloud, and like a snow ball on the trees, this is the foil flower leaves! 5、The contrast between the flowering cherry blossoms is very small, but in the same tree, you can also see the various forms of flowers. Some of them are budding, the flowers are different from the branches, and they seem to have an unspoken fear of the outside world. Some have just blossomed, like babys smiling face, sweet and pure, can not stand any wind and rain, but still lovable; The blossoming cherry blossoms, like a group of lively and lovely children, make up a rich and full happy paradise, and many generations live together. It is like a young girl standing tall and erect, but she is full of vitality and graceful. 6、Spring came, and the branches of the cherry trees were brightly colored. The flowers were small and small, and the five or six gathered together to form a flower ball, clustered in clusters on the branches, stretching the long, narrow petals and the flowers wrapped in them. 7、The varieties of sakura are different, its leaves are different, some are green and smooth, some are red and rough, others are green inside, but the edges are red... The sakura bark is dark brown, which is exactly the way it is decorated with pink cherry blossoms, but it doesnt seem to be able to hide its own qualities or qualities. The petals of the cherry blossom have three or five flowers each, which are in the form of umbrella-shaped inflorescences, which are carried out at the level of sepals, giving off a faint scent of flowers... 8、On both sides of the road are beautiful cherry blossoms. There are two varieties, one of which was opened in February, and the red cherry blossom of the double flaps, and we can see a little bit more sporadically. While the flowers are blooming with sweet pink blossoms, we often see them in the pictures. I stand under the tree and look at them carefully, looking at them as if they were the flowers. I dont know if peach blossoms are related to cherry blossoms, but they are as indistinguishable as twin sisters. Of course, as long as you observe carefully, you will find that their branches are different, and the peach tree trunks are darker and brighter. According to the introduction, there are more than 10,000 cherry trees here. 9、Springs favorite flower is cherry blossom. Often overnight, its open. Sudden, overwhelming. Then fall in the wind. There is no nostalgia. The Japanese call it flowers blowing snow. At dusk, walking through the cherry trees, the white petals are still fluttering. It suddenly occurred to me that this was the most extravagant flower. Because it dies early. 10、The cherry blossoms have blossomed into beautiful cherry blossoms, and they have blossomed into a beautiful and sad love. Love will eventually fall, which is the unchangeable fate of beautiful things. Good and short, like cherry blossoms. 11、The leaves of the cherry blossoms are water droplets, with tiny little pubescent hairs on the edges, and the leaves of the stem are glimmering, just when the green light is shining. The red flower needs a foil, which is true. Although it has always been a supporting role, it still brings a green meaning to people. The thick trunk was brown and the surface was waxy and smooth. 12、The cherry blossom is dark red, a bit like a single pink peach blossom, but the flower is smaller than peach blossom, and the flower shape is not as beautiful as peach blossom. I dont know whether I was bullied by the cold rain last night, and every flower was drooping, like the little girl who was angry. 13、Cherry blossoms, will be allergic to the spring season, open-minded heaven, smoothing out the blundering heart, be familiar with simple words said to people will understand, silly childish tomorrow, dancing like you hair, allow me to cherish not small rely on silent in uproar, want to meet spring flowers and plants leave will have new harvest, waiting for the spring the filar silk like subtle miracles will happen, I heard that day there is cloud in nestle, and found that the accumulation of change, faintly see the tail of a lion, believe think again beautiful also learn the scene ahead in the dawn of the garden Yang, I feel special, I understand you have a window, you will see the melting love, no plan no adventure, happy every day, a warm glow. 14、Looking at the cherry blossoms, they are very disappointed. The cherry blossom is dark red, a bit like a single pink peach blossom, but the flower is smaller than peach blossom, and the flower shape is not as beautiful as peach blossom. I dont know whether I was bullied by the cold rain last night, and every flower was bowed down, like a little girl in anger, more like a Japanese womans bow and a smile. I think this is the origin of the Japanese national flower, and may also be able to say why the Japanese women are so bent over a shallow smile. 15、I proud, never make public, I want to, but never say, I just like to see cherry blossoms flutter sinks down, quietly watching the clouds drift in the feet, see the wind blowing hair, I want to sleep in parents arms, in brother Xiao Sheng piano company, however, all this is nothing but just desire, they who also can not give, I can only be a person lonely wandering, like abandoned. 16、We do not have to admire her beauty, just to be able to quietly smell her fragrance, the thin ice, and enjoy the dreamlike cherry blossoms. I gently walked to a cherry tree, unable to resist the impulse of the heart, tiptoe, carefully folding a cherry tree, sitting on the lake on the lakeside stone bench, carefully studied. The petals of the petals of the petals are so that they are not vulgar, but the subtle aroma of the heart. 17、The teacher took us to the cherry garden, looking at the pink one, like a large pink cloud, floating, floating, tired, just stop there. Close look, pink petals and green leaves all the oval, the blossom in yellow white, is white, under the above is yellow, very small, like a touch will be broken, so we just cant touch.

The childrens laughter and the breeze, drifting far, far away... 20、Remember the first time to see the cherry blossom, a spring rain like a date, the petals rain wind blowing. The flowering period is just over a week, so brief and so gorgeous. 21、The petals of sakura are from the edge to the center, from pale pink to pure white; Pink, like a babys innocent smile, white, like the worlds snow. I cant help but gently stroke it, soft as the silk of the jiangnan. The edges of the petals are microwaves, like microwaves on a pink ocean, and the real thing is the "waves" of flowers. The stems are slender and soft, as thin as a green silver thread, as soft as a girls fair figure, from top to bottom, from thick to thin, from brown to green, supporting delicate flowers. 22、Cherry blossoms are a natural reward, but they are also a spectacle.

Always in such a moment, with a piece of rain, gliding through the edge of the cherry blossoms in the paths of my soul. Cherry blossoms are in the rain. The cherry blossoms in the rain, but when we are not casual, tranquility becomes a profound commemoration, yes, in the days of luojiashan, it is our luckiest time, the most pure desire. 25、When we go out, we have a thick spring. We "traveled through the mountains and rivers" and came to yuyuantan. As soon as you enter the door, there are countless petals fluttering in the air, flying in front of our eyes. Standing in the thick shade of trees, the feeling of weariness of the day seemed to vanish, and the breeze lifted my heavy mouth. Walking forward, there was open water. The golden sun was shining on the water, as if it had covered the smooth surface of the lake with gold. 26、Area has come to cafe DE jack cherry blossoms, maybe this time missed the cherry blossom the most splendid time, a lot of cherry blossoms fade, falling slope, steps on the flower piece, formed the strips trail was paved with flowers, people walk while watching the cherry blossom, also another scenery! Although there are a lot of flowers, but there are still a lot of cherry trees, still bright, they spread a beautiful smile, welcome guests. 27、The cherry blossom is a beautiful flower.

They are important ornamental plants for early spring. They are often used in garden viewing, and they can be planted in groups or in front of roadside buildings in hillside courtyards. Blooming time flowers are gorgeous, full of trees, like clouds, extremely spectacular. The landscape of flowers and sea can be planted in large areas, and the three or five clusters of trees can be planted in the green space to form a brocade, which can also be isolated to form a little red color among the green clusters. Cherry trees can also be used as path trees and hedges or bonsai. In addition, bark and fresh tender leaves can be used medicinally. Some people make jam and condiments in Japan by grinding the flowers of cherry blossoms into nectar. 29、Look, so many dye color cotton candy to float in the air, that is tall, the cherry blossom on the cherry trees, let people see the couldnt help thinking the school gate at the bound on the stick to sell cotton candy, really want to eat a few mouth snack; Come a little closer, the cherry blossoms are in clusters, clusters, more like a branch of melting ice cream; A little closer to see it, flying in the air, still white with pink, just like the snow in the winter makeup general beauty. 30、Beautiful cherry blossoms, white pink, in the breeze, sometimes embracing; Sometimes crooning; Now and then he lowers his head and whispers; Or head laughed, this beautiful scene, touches everyones nerves, they at the same time of ornamental, keep out of the cell phone camera take pictures, posing a variety of poss, leave this happy and beautiful scene good memories! 樱花的浪漫短句英文2 （一） 樱花盛开，这里的春天是浪漫的。 （二） 一根樱树枝上，往往只开几朵小花，但花开的姿态却各有不同。 （三） 四月的阳光，唤醒了沉睡的樱花。 （四） 樱花盛开的季节，童年的记忆又涌上心头。 （五） 那满树的樱花散发出一阵阵淡淡的清香，让人心旷神怡。 （六） 樱花，是一种美丽的小花。 （七） 樱花的美，在于枝头的花，在于风中的香，在于一树一花的美妙。 （八） 阳春三月，我能想到最浪漫的事，就是陪你一起去看樱花雨。

A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth"s atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arc and violet on the inner section of the arc.A rainbow spans a continuous spectrum of colours; the distinct bands are an artifact of human colour vision. The most commonly cited and remembered sequence, in English, is Newton"s sevenfold red, orange, yellow, green, blue, indigo and violet (popularly memorized by mnemonics like Roy G. Biv). Rainbows can be caused by other forms of water than rain, including mist, spray, and dew.

托福阅读指代题虽然考的是代词，却暗含着对指代关系、语篇逻辑的深层考察，并非单纯词汇层面的考察。根据代词的不同类别，我们把托福阅读指代题分成四大类型：人称代词类、指示代词类、关系代词类和不定代词类。具体请看下文! 托福阅读指代题四大类代词关系梳理 托福阅读考试中指代题是不可忽视的一大题型，虽然考的是代词，却暗含着对指代关系、语篇逻辑的深层考察，并非单纯词汇层面的考察。通常的提问形式体现为“The word they/their/it/its/some in the passage refers to______”，然后给出四个选项，这四个词通常都是原文中出现过的生词，并且往往都是在they/their/it/its/some这几个词的附近，需要考生经过严密思考推测，选出一个既符合行文逻辑又符合上下文意思的选项。 那么我们如何明确判断代词所指代的对应内容呢?我们可以根据代词的不同类别，把指代题分成四大类型：人称代词类、指示代词类、关系代词类和不定代词类。然后就可以根据不同类别的代词特征一一解答了。下面我们来具体看一下四大类代词的特征及辅助解答托福阅读指代题的策略。 第一类，人称代词 人称代词主要包括：I，you，he，she，it，we，they，me，him，them，yours，his，her，its，their等。此类题型应在做题时根据代词的单复数及其所能指代的名词来判断，通常是往前找最近的核心名词。 例如： “An auction is a popular way of buying and selling. It is a useful way of deciding the value of things。” The word It in the passage refers to __________。 A. theory B. price C. process D. auction 往前追溯单数形式的核心名词，并且能用在第二句的主语位置的词，就只能是第一句中出现的auction一词了，所以正确答案选D。 第二类，指示代词 指示代词主要包括this, that, these, those等。在这种 句子 中，this和that通常指代某个观点事物或现象，而these和those通常指复数形式下的某些观点事物或意见，并且该类题也遵循往前找的原则。 例如： “The dragon also has large claws that are used when it is younger. It uses these to climb trees to escape from the jaws of older dragons. But when they get older， these claws are used mainly as weapons。” The word these in the passage refers to __________。 A. claws B. trees C. jaws D. weapons 该题中的these一定是指之前已经出现过的名词，所以现在才能用代词进行指示，因此我们首先可通过往前追溯的原则进行排出，B、C、D瞬间就都被排除了。再将A选项带入原句验证，看逻辑和意思是否与句意相符，最终验证表明，答案正是A选项。 第三类，关系代词 主要包括which, that, who, whom等。在这种句子中，通常采用就近原则。尤其是由“， which”格式引导的从句，一般都是非限制性定语从句，通常就是指该词前面紧挨着的名词。但需要注意的是，当关系代词前有插入语时，需要先去掉插入语，再使用就近原则。 例如： “Scientists have been looking for energy sources to replace oil. They have studied wind，ethanol，and nuclear energy. They have also started to look at coal again. Coal，which is the cheapest energy source，is found in many parts of the world. However，it is dangerous to mine. It also pollutes the environment。” The word which in the passage refers to __________。 A. nuclear energy B. ethanol C. wind D. coal 一看词句考察的是由which引导的非限制性定语从句，则毫不犹豫得把答案定位到which前的名词“coal”上，所以一眼就能选出该题的正确答案D选项。 第四类，不定代词 主要包括some，any，every，each，none，some...others...，one...,another等。这类代词通常指的都是该词前后与其关系最紧密的名词主语，并且注意词的单复数形式。 例如： “Some studies show that one in eight plant species is threatened with extinction. It is estimated that 140000 species of plants are lost each year. Many of these lost plants could have been very useful in creating new drugs to combat disease。” The word Many in the passage refers to __________。 A. studies B. plant species C. lost plants D. new drugs 首先确定该题的“Many”所在句主语应该是指“lost plants”，并且“of”是表示所属的关系，所以“Many”应该是属于“these lost plants”中的一部分，所以很显然“Many”指的就应该是“lost plants”，因此答案选C。 需要注意的是这四大类代词只能大致涵盖托福阅读指代题中所涉及的大致类型，要想全面把握托福阅读指代题，我们还是需要把握好真题，结合解题技巧与策略进行有针对性的练习与 总结 ，循序渐进提高托福阅读水平与分数。 托福阅读指代题解题思路及步骤 一、问题形式 被考的 文章 中有一个词或词组被加亮，这个词通常是一个代词或名词。指代题的形式如下： The word (or phrase) X in the passage refers to 二、解题步骤 1. 根据解题技巧确定答案 2. 代入原文验证，看语义、逻辑和语法上是否通顺 三、基本原则 1. 就近指代 所谓就近指代，就是被指代对象通常在指代词前不远处，如本句或上一句中。有时也出现在更前面的一句中。例如， Large wind farms might also interfere with the flight patterns of migratory birds in certain areas, and they have killed large birds of prey (especially hawks, falcons, and eagles) that prefer to hunt along the same ridge lines that are ideal for wind turbines. The killing of birds of prey by wind turbines has pitted environmentalists who champion wildlife protection against environmentalists who promote renewable wind energy. Researchers are evaluating how serious this problem is and hope to find ways to eliminate or sharply reduce this problem. The phrase this problem in the passage refers to interference with the flight patterns of migrating birds in certain areas building ridge lines that are ideal for wind turbines the killing of birds of prey by wind turbines meeting the demands of environmentalists who promote renewable wind energy 本题涉及的是一个词组this problem。寻找这一词组的指代对象时只需向上搜索就行。根据就近原则，前一句中的主语the killing of birds of prey by wind turbines可以初步确定为答案。将其代入原文，符合语义和逻辑，因此第三个选项为正确答案。第一个选项和第三个选项都和this problem相距较远，而且代入时语义和逻辑上不通，因此为干扰选项。 2. 数格一致 被指代对象通常与指代词在数(如单数或复数)和格(主格或宾格)两方 面相 同。如单数代词one指代单数名词，复数代词they指代复数名词。 四、主要思路 1. 主从复合句中的指代 在主从复合句中，第二句的代词主语经常指代第一句的名词主语。例如， The fins are stiff, smooth, and narrow, qualities that also help cut drag. When not in use, the fins are tucked into special grooves or depressions so that they lie flush with the body and do not break up its smooth contours. The word they in the passage refers to ?qualities ?fins ?grooves ?depressions 在这一例子中，从句so that they…中的代词主语they指代主句的名词主语the fins，因此第二个选项为正确答案。 新托福阅读背景知识：植物适应沙漠 Plant adaptation to the desert(背景材料) Cactus adaptations. The secret to the superior endurance of cacti lies in their adaptations. Over millions of years, through natural selection, only the strongest and best adapted species survived. As you know, it is very dry in the desert. Plants that adapt to this are known as xerophytes (from zeros, dry and python, plant). There are plants that avoid the dry season by sprouting from seed just after the spring rain and growing very fast so that by the time the dry season comes, they have already produced a lot of seeds and died. These seeds lie on the soil for the dry season and sprout again in spring and the cycle repeats. Other xerophytes simply drop their leaves and stay dormant for the winter. But there is another special type of xerophytes which stores water in its fleshy tissues. Such plants are called succulents (from success, juicy). The cactus is a typical example of a succulent. If you cut a cactus open, you see a juicy, slimy tissue. This is where the moisture is stored for the dry season. The part between the middle circle (and pith) and just under the very green part of the plant (or palisade parenchyma) just under the skin is allocated for the storage of water and food for the plant. This is a type of spongy parenchyma and can take up to 85% of the plant"s volume. This is a major adaptation in the desert. Because the plant remains completely alive during the dry season and there is no need for it to dry up and lose everything, makes it possible for the plant to grow to large sizes. Another advantage is that the plant retains supplies (in the form of starch) for the winter so that it can flower right away in spring without accumulating more supplies (as most plants need to do in spring). The whole purpose of storing supplies for the winter is mostly to energize flowering in spring but it also lets the cactus start growing much sooner. Flowering plants breathe and transpire (evaporate water from their surface) through closeable microscopic pores called stoats on the leaves or stems. To do this, their pores have to be open. In most plants these are open all day and on warm nights. But for cacti this is inconvenient as in daytime it is very hot and thus the plant would lose a lot of water through evaporation. So the cactus must close them in the daytime. But then it cannot breathe or photosynthesize (the process where sugars are made from carbon dioxide and water and releasing oxygen using the sun"s energy). Succulents have an adaptation to that. Their stoats are closed during the day and are open at night, when it is not that hot and store carbon dioxide in its tissues as crass lean acid and then turn it back to carbon dioxide in the daytime. This process is called crass lean acid metabolism or CAM and it is a very smart way of respiring in the desert. If we look at the outside of the plant, we notice that there is a tough leathery skin covering the plant, we can also notice the presence of ribs and spines and sometimes fur. These are all very smart adaptations. They serve mainly for surviving heat but are also used as defense. The tough leathery skin is very impermeable to water, thus reducing evaporation from the surface of the plant. This skin often has a layer of plant wax on it which is often lightly colored (Pilosocereus azures is an example of a plant with such wax), white or blue. This reflects light and also reduces evaporation from the inside. The ribs are special structures that are also used for enduring extreme heat. The ribs (and spines) trap wind so that the plant is enveloped in a layer of extremely still air, and this is a very important factor in reducing evaporation. On very windy days even the ribs don"t help and cacti sometimes wilt because of high water loss. The spines have different functions. They not only help shade the plant from the sun but are also known to help the cactus absorb water. They do it like this. On cool nights, dew settles on the spines of the plant. The spines are actually known to draw droplets of water towards the areole (the point out of which the spines grow) and here the droplets are absorbed. You can try this at home. Spray the plants with a very fine mist of water and watch what happens to the droplets that settle on the spines. They literally get attracted to the areole along the spine. The spine"s structure allows them to do this. Even spines pointing downwards seem to suck the droplets up themselves. Adaptation features are visible in this Pilosocereus glauchochorous. Notice the spines, ribs, fur and wax (the blue coloration). The top of a typically adapted plant. Some plants have fur; sometimes all over the plant, sometimes only near the top. This fur shades the plant even further and is also known to attract water towards the areole. Some plants only have fur near the top. This is very beneficial because the top of the plant is very sensitive to sunlight, new tissues get formed there. Young areoles, with their spines not even wooded yet can get dried up completely in the sun. When an areole is born near the top of the plant, it starts developing spines. At this time the fur appears as well. This fur accompanies the areole as it moves down the plant, shading the growing point inside. By the time the areole is about 15cm away from the top, the fur wears out completely and the now inactive areole gets exposed to the sun. As for the roots of cacti, they are also fully adapted to living in the desert. Some species (especially plants from very dry deserts) have very shallow root systems that spread very far from the plant. This way the plant can take advantage of tiny amounts of moisture from dew or light rain as the roots spread far away and are very shallow (less than 10cm deep while spreading up to 5 meters from the parent plant). On the other hand, some cacti send their roots deep down (like many Echinocacti) to reach the ground water. Rainforest cacti often have aerial roots that can collect water all the time when it rains (and it rains very often in South American forests). The shape of cacti itself is an adaptation. You may have noticed that cacti have a barrel like or candle like shape. This allows for maximum internal volume with a minimum surface area, which is also very smart adaption as a cactus can store a lot of water and have a small external surface area to reduce water loss.

阅读理解：词义题详解 　　众所周知，在英语学习中，我们自然会遇到许多生词。这时，许多人立即翻阅字典，查找词义。其实，这种做法是不科学的。它不但费时费力，而且影响阅读速度。事实上，阅读 材料中的每个词与它前后的词语或句子甚至段落有着互相制约的关系。我们可以利用语境(各种已知信息)推测、判断某些生词的词义，因为考研阅读部分的词汇题 要考的并不是考生认不认识题中所考的单词，真正要考的是考生阅读中的推断能力，也就是说题中所考单词的词义必定能根据上下文推断出来。推断出词义后，可将词义代入原文看是否通畅来判断自己的推测是否准确。下面就让我为大家详解一下吧。 　 　例如2003年第54题： 　　Railroads justify rate discrimination against captive shippers on the grounds that in the long run it reduces everyoneu2019s cost. If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. Itu2019s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. “Do we really want railroads to be the arbiters of who wins and who loses in the marketplace?” asks Martin Bercovici, a Washington lawyer who frequently represents shippers. 　　The word “arbiters” most probably refers to those_________. 　　[A] who work as coordinators 　　[B] who function as judges 　　[C] who supervise transactions 　　[D] who determine the price 　　该题的解题关键在于是否知道arbiters后的介宾短语of who wins and who loses in the marketplace就是对该词的最准确定义，依据该介宾短语，不难得出arbiters是决定谁输谁赢的人，四个选项中只有B选项和这个意思最为接近。 　 　再例2004年第43题： 　　For any job search, you should start with a narrow concept—what you think you want to do—then broaden it. “None of these programs do that,” says another expert. 　　“There"s no career counseling implicit in all of this.” Instead, the best strategy is to use the agent as a kind of tip service to keep abreast of jobs in a particular database; when you get E-mail, consider it a reminder to check the database again. “I would not rely on agents for finding everything that is added to a database that might interest me,” says the author of a job-searching guide. 　　The expression “tip service” most probably means . [A] advisory 　　[B] compensation 　　[C] interaction 　　[D] reminder 　　该题的解题关键在于充分利用分号，分号前面的.短语use the agent as a kind of tip service和分号后的consider it a reminder属于并列关系，it和the agent都是指的文章中所说的搜索代理，自然我们就找到了tip service的同义词reminder。所以该题答案D。 　　根据考研英语阅读理解词义题破解的总体原则，可以总结出两种具体的词义题解题方法： 　　1. 内在逻辑关系法。即根据内在逻辑关系推测词义是指运用语言知识分析和判断相关信息之间存在的逻辑关系，然后根据逻辑关系推断生词词义或大致义域。 　　a.根据对比关系猜测词义 　　在一个句子或段落中，有对两个事物或现象进行对比性的描述，我们可以根据生词或难词的反义词猜测其词义。例如： 　　Andrew is one of the most supercilious men I know. His brother, in contrast, is quite humble and modest. 该例中supercilious对许多人来说可能是个生词，但是句中短语in contrast，(相对照的，相对比的)可以提示我们supercilious和后面词组humble and modest(谦卑又谦虚)是对比关系。分析出这种关系后，我们便能猜出supercilious意为“目空一切的，傲慢的”。 　　表示对比关系的词汇和短语主要是unlike，not，but，however，despite，in spite of，in contrast 和while 引导的并列句等。例如，A good supervisor can recognize instantly the adept workers from the unskilled ones. 该句中并未出现上面提到的表示对比关系的词或短语，但是通过上下文可以判断出句子前后是对比关系，即把熟练工人与非熟练工人区分开。这时我们也能够推断出生词 adept的词义为“熟练的”。 　　b.根据比较关系猜测词义 　　同对比关系相反，比较关系表示意义上的相似关系。 　　例如：Green loves to talk，and his brothers are similarly loquacious. 　　该句中副词similarly表明短语loves to talk与生词loquacious之间的比较关系。以此可以推断出loquacious词义为“健谈的”。表示比较关系的词和短语主要是similarly，like，just as，also等。 　　c.根据因果关系猜测词义 　　在句子或段落种，若两个事物、现象之间构成因果关系，我们可以根据这种逻辑关系推知生词词义。 　　例如：Tom is considered an autocratic administrator because he makes decisions without seeking the opinions of others. 根据原因状语从句的内容，我们可以推断出生词autocratic指“独断专行的”。There were so many demonstrators in the Red Square that he had to elbow his way through the crowd. 此句为结果状语从句，根据从句的描述“许多示威者”，我们便可推知elbow的词意“挤，挤过”。 　　d.根据同义词的替代关系猜测词义 　　在句子或段落种，我们可以利用熟悉的词语，根据语言环境推断生词词义。 　　例如： Although he often had the opportunity, Mr. Tritt was never able to steal money from a customer. This would have endangered his position at the bank, and he did not want to jeopardize his future. 作者为避免重复使用endanger一词，用其同义词jeopardize来替代它，由此推知其词义为“使u2026u2026陷入危险，危及、危害”。 　　Doctors believe that smoking cigarettes is detrimental to your health. They also regard drinking as harmful. 句中detrimental是个生词，但判断出harmful替代detrimental后，不难推断出其词义为“不利的，有害的”。 　　2. 外部相关因素法。外部相关因素是指篇章(句子或段落)以外的其他知识。有时仅靠分析篇章内在逻辑关系无法猜出词义。这时就需要运用生活经验和普通常识确定词义。 　　例如： Husband：Itu2019s really cold out tonight. Wife: Sure it is. My hands are practically numb. How about lighting the furnace? 根据生活经验，天气寒冷时，手肯定是“冻僵的，冻得麻木的”。 　　The snake slithered through the grass. 根据有关蛇的生活习性的知识，我们可以推断出slither词义为“爬行”。 　　在猜测词义过程中，除了使用上面提到的一些技巧，我们还可以依靠构词方面的知识，从生词本身猜测词义。 　　此外利用词缀亦不失为一种有效的手段。 　　a.根据前缀猜测词义 　　例如：He fell into a ditch and lay there, semiconscious, for a few minutes. 根据词根conscious(清醒的，有意识的)，结合前缀semi(半，部分的，不完全的)， 我们便可猜出semiconscious词义“半清醒的，半昏迷的”。Iu2019m illiterate about such things. 词根literate意为“有文化修养的，通晓的”，前缀il表示否定，因此illiterate指“一窍不通，不知道的”。 　　b.根据后缀猜测词义 　　例如：Insecticide is applied where it is needed. 后缀cide表示“杀者，杀灭剂”，结合大家熟悉的词根insect(昆虫)，不难猜出 insecticide意为“杀虫剂”。 Then the vapor may change into droplets. 后缀let表示“小的”，词根drop指“滴，滴状物”。将两个意思结合起来，便可推断出droplet词义“小滴，微滴”。 　　c.根据复合词的各部分猜测词义 　　例如：Growing economic problems were highlighted by a slowdown in oil output. highlight或许是一个生词，但是分析该词结构后，就能推测出其含义。它是由high(高的，强的)和light(光线)两部分组成，合在一起便是“以强光照射，使突出”的意思。 Bullfight is very popular inSpain. Bull(公牛)和fight(打，搏斗)结合在一起，指一种在西班牙颇为流行的体育运动——斗牛。 　　在熟练掌握根据上下文推测生词含义的同时，考生也应重点避免以下两种情况：第一，随便猜一个选项，这样错误率很高。第二，没有掌握阅读词汇题的基本命题原 则，落入命题专家的陷阱，不知不觉地失了分。所以考生在遇到阅读中的词汇题时，一定要冷静，认真在上下文中寻找相关信息。这是一项非常重要的阅读技巧。可以让我们排除生词的障碍，充分理解文章的思想内容，提高阅读速度。 ;

Rain (rain) from the cloud droplets to land, land and ocean surface water evaporated into water vapor, water vapor rises to a certain height into a small drop of water after the case of the cold, these small water droplets to form clouds, the clouds where they are with each other collision of water droplets merge National Cheng Kung University, when it is big into the air care do not live, when falling behind down from the clouds to form rain. Rain causes of the diversity of its manifestations are also distinctive, with drizzle, there is incessant rain, as well as under the torrential showers. Rainwater is the most important human life, fresh water resources, plants also rely on rain to nourish and grow. However, the floods caused by heavy rains also caused tremendous suffering to human beings.Earth"s water under sunlight irradiation, it becomes water vapor is evaporated into the air went. Encounter the cold air at high altitude water vapor can gather into small water droplets. These small droplets are very small, only 0.01 to 0.02 millimeters in diameter, the largest is only 0.2 mm. They are also small and light, was in the air updraft care in the air. Is that these small water droplets in the air and gather into clouds. These small water droplets to turn into raindrops fell to the ground, which is about to be increased more than 100 million times. These small water droplets is how to make their volume grew to more than 100 million times it? It mainly rely on two instruments, one is the condensation and sublimation increases. The second is to rely on cloud droplet collision and increase. In the early stages of the formation of raindrops, cloud droplets mainly depend on continuously absorbing the water vapor cloud around the body to make its own condensation and sublimation. If the water vapor cloud body to be able to continuously supply and supplement to the cloud droplet surface, often at too saturated, then the condensation process will continue, with the growing cloud droplets become raindrops. But sometimes cloud the water vapor is limited, in the same piece of cloud, the water vapor is often in short supply, so it is impossible to make every cloud droplets are larger for larger raindrops, some of the smaller cloud droplets had to be integrated into a larger of cloud droplets and going. If the cloud water droplets and ice crystals coexist inside a case, then this increase in the process of condensation and sublimation will be greatly accelerated. When the cloud of cloud droplets increases to a certain extent, due to large cloud droplets increase the size and weight, they drop the course will not only catch up with slower Xiaoyun drops, but also "annexation" more drops of Xiaoyun allowed itself to expand. When the big cloud droplets get bigger, the last big into the air can no longer care do not live it, begins with self-contained cloud to the ground, our common rain.Are many kinds of rain, in addition to acid rain, there is the color of rain, there are many interesting rain, such as frogs rain, iron rain, golden rain, rain and even money. They are a masterpiece of a tornado.

1. 在雨天的英语作文怎么写（要用现在时） Weather Weather changes with seasons--cold with snow in winter, hot with rain in summer and mild with sunlight in spring and autumn.I like the weather with sunshine because sunny weather make people pleasant and happy. But I really don"t like the weather in Beijing very much for it is very dry and windy in autumn, and this is the city"s typical weather. Yet the weather I like most in Beijing is spring and summer. In spring flowers bloom and trees turn green and everything are full of vigor.In summer the city is decorated with flowers and green coverings almost everywhere.I think the best weather for Beijing 2008 Olympic Games is the season of late summer and early autumn. So I hope it is going to be held in this season.I also agree that usually sunny weather can make people happy while rainy or cloudy or windy weather can make people in low-spirit for people tend to be more active and fortable in sunny weather.So nobody really likes windy and rainly weather and instead almost all like sunny one. 翻译：天气 天气随季节变化，冬天寒冷下雪，夏天炎热下雨，春秋温和而阳光充足。 我喜欢晴朗的天气因为明媚的阳光使人心情舒畅。但我却不太喜欢北京的秋天，干燥而风大是北京的典型天气。 我最喜欢北京的春天和夏天。春天，百花盛开，树木变绿，一切都充满了生机活力。 夏天，整个北京到处点缀着鲜花和绿地。我认为2008年北京举办奥运会的最好季节是夏秋之交，真希望能在这个时候举办盛会。 我同意这样的观点：晴朗的天气使人愉悦，而阴天，下雨或刮风的天气使人心情压抑，因为晴朗的天气里人们会觉得活跃和舒适。因此，没有人喜欢刮风下雨天，而是都喜欢阳光明媚的天气。 2. 写雨的英语小作文 老师：Miss Li is my Chinese teacher .

When a mass of air quickly cools to its saturation point, the water vapor condenses into clusters of tiny water droplets and frozen water crystals. We call these clusters clouds. Over time, the droplets and crystals that make up a cloud can attract more water to themselves. When water droplets grow heavy enough, gravity pulls them down as raindrops. If the air is cold enough, the ice crystals can remain frozen and grow large enough to fall as snow, sleet, freezing rain or hail. Raining is earth"s natural phnomenon. Hot air evaporate steam up the sky, just like the above process and make cloud and when meets with the cold air, which makes the evaporated steam changes into water drops and fall down onto Earth again. It repeated again and again for thousands of years. So this is rain. 4.

I lied in bed sleepless, listening to the rain dropping down softly on the roof. It was just like the music. I was deeply moved by it. Rain in spring is not like rain in autumn or summer. It drizzles sometimes, moistening the thirsty fields lightly and selflessly. I apparently feel the fresh breeze together with raindrops blowing against my window. 这是一个春天的雨夜。我躺在床上，聆听着雨滴温柔地敲着房顶，像音乐一般。这样的雨夜我无法入睡，我被深深地感动了。春雨不像秋雨，也不像夏雨。它大多是毛毛细雨，轻柔而又无私地滋润着干涸的大地。我分明感觉到清爽的微风夹杂着雨滴吹进了我的窗户。

General Information Acid rain (or more accurately acid precipitation)[1] occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere undergo chemical trformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain snow or sleet. This can increase the acidity of the soil and affect the chemical balance of lakes and streams.[2] The term "acid rain" is sometimes used more generally to include all forms of acid deposition - both wet deposition where acidic gases and particles are removed by rain or other precipitation and dry deposition removal of gases and particles to the Earth"s surface in the absence of precipitation.[3] Acid rain is defined as any type of precipitation with a pH that is unusually low.[4] Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2.[5] Therefore a pH of less than 5.6 has sometimes been used as a definition of acid rain.[6] However natural sources of acidity mean that in remote areas rain has a pH which is beeen 4.5 and 5.6 with an average value of 5.0 and so rain with a pH of less than 5 is a more appropriate definition.[7] The US EPA says "Acid rain is a serious environmental problem that affects large parts of the US and Canada" [8] Acid rain accelerates weathering in carbonate rocks and accelerates building weathering. It also contributes to acidification of rivers streams and forest damage at high elevations. Adverse effects Soils Soil biology can be seriously damaged by acid rain. Some tropical microbes can quickly consume acids[11] but other types of microbe are unable to tolerate low pHs and are killed. The enzymes of these microbes are denatured (changed in shape so they no longer function) by the acid. The hydronium ions of acid rain also mobilize toxins and leach away essential nutrients and minerals [12]. [edit] Forests and other vegetation Acid rain can slow the growth of forests cause leaves and needles to turn brown and fall off and die. In extreme cases trees or whole areas of forest can die. The death of trees is not usually a direct result of acid rain often it weakens trees and makes them more susceptible to other threats. Damage to soils (see above) can also cause problems. High altitude forests are especially vulnerable as they are often surrounded by clouds and fog which are more acidic than rain.[12] Other plants can also be damaged by acid rain but the effect on food crops is minimised by the application of fertilizers to replace lost nutrients. In cultivated areas limestone may also be added to increase the ability of the soil to keep the pH stable but this tactic is largely unusable in the case of wilderness lands.[12] Acid Rain depletes minerals from the soil and then it stunts the growth of the plant. 落埋subtitle架啦，应该几易睇，净系节录左introduction同有关effect to the plant比你，其余可以去en. *** /wiki/Acid_rain#Forests_and_other_vegetation睇 参考: Webpage Acid rain can perate into the soil can mix with water when the plant absorb water from the soil the acid in water will affect the enzyme acticity like photosynthesis and respiration since they are controlled by enzyme.

It also contributes to acidification of rivers streams and forest damage at high elevations. Natural emissions The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes and those from biological processes that occur on the land in wetlands and in the oce. The major biological source of sulfur containing pounds is Dimethyl sulfide. The effects of acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe. [edit] Human emissions The principal cause of acid rain is sulfur and nitrogen pounds from human sources such as electricity generation factories and motor vehicles. The gases can be carried hundreds of miles in the atmosphere before they are converted to acids and deposited. [edit] Gas phase chemistry In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via a termolecular reaction: SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water sulfur trioxide (SO3) is converted rapidly to sulfuric acid: SO3 + H2O → H2SO4 Nitric acid is formed by the reaction of OH with Nitrogen dioxide: NO2 + OH· → HNO3 For more information see Seinfeld and Pandis (1998).[5] [edit] Chemistry in cloud droplets When clouds are present the loss rate of SO2 is faster than can be explained by gas phase chemistry alone. This is due to reactions in the liquid water droplets Hydrolysis Sulfur dioxide dissolves in water and then like carbon dioxide hydrolyses in a series of equilibrium reactions: SO2 (g)+ H2O u21cc SO2·H2O SO2·H2O u21cc H++HSO3- HSO3- u21cc H++SO32- Oxidation There are a large number of aqueous reactions of sulfur which oxidise it from S(IV) to S(VI) leading to the formation of sulfuric acid. The most important oxidation reactions are with ozone hydrogen peroxide and oxygen (reactions with oxygen are catalysed by Iron and Manganese in the cloud droplets).

In the cloud, cloud droplets are small water droplets. They continue to rely mainly on condensation and collisions compounded. Therefore, in the cloud droplets, aiming to increase the size of the rain, first of all need a very thick cloud, dense cloud droplets, moisture content, so, it can continue to grow condensation; secondly, in Shuiyun also requires the presence of strong vertical motion, so in order to increase the number of collision and the machine will. In relatively thin and relatively stable Shui-yun, cloud droplets do not have enough condensation and combined growth opportunity, can cause cloudy, cloudy, the Congress does not rain. In different kinds of clouds, the cloud droplet size distribution is different, resulting in cloud droplet size uneven reason is around in the air and moisture transfer of cloud droplets evaporate. The cloud droplet growth factor is the setting process and the collision and process, only to condense in the circumstances, the size of the cloud droplets are uniform, but because of the added water vapor, so that some increase in cloud droplets, and together with the and the results, so that the larger cloud droplets continue to grow into big raindrops. Suffer the effect of gravity raindrop falling, when updraft, will have an upward force in rain, make its slow down, and a little rain may also be brought up. Only when the rain increased to a certain extent, to fall to the ground, the formation of rain.

The air is normally cooled by expansion during its upward movement. Upward flow of air in the atmosphere may be caused by convection resulting from intense solar heating of the ground; by a cold wedge of air (cold front) near the ground causing a mass of warm air to be forced aloft; or by a mountain range at an angle to the wind. Clouds are occasionally produced by a reduction of pressure aloft or by the mixing of warmer and cooler air currents. 海洋、湖面、植物表面、土壤里的水分，每时每刻都在蒸发，变成水汽，进入大气层。含有水汽的湿空气，由于某种原因向上升起。在上升过程中，由于周围空气越来越稀薄，气压越来越低，上升空气体积就要膨胀。膨胀的时候要耗去自身的热量，因此，上升空气的温度要降低。温度降低了，容纳水汽的本领越来越小，饱和水汽压减小，上升空气里的水汽很快达到饱和状态，温度再降低，多余的水汽就附在空气里悬浮的凝结核上，成为小水滴。如果温度低于冰点，多余的水汽就凝华成为冰晶或过冷却水滴。它们集中在一起，受上升气流的支托，飘浮在空中，成为我们能见到的云。

你好汉语彩虹是气象中的一种光学现象.当阳光照射到半空中的雨点,光线被折射及反射,在天空上形成拱形的七彩的光谱.彩虹的七彩颜色究竟是哪七种有不同的说法,中国最普遍的说法是（从外至内）：红、橙、黄、绿、青、蓝、紫.西方的说法是：红、橙、黄、绿、蓝、靛 (Indigo)、紫,源于科学家牛顿分解七原色后取的名字.其实只要有空气中有水滴,而阳光正在观察者的背后以低角度照射,便可能产生可以观察到的彩虹现象.彩虹最常在下午,雨后刚转天晴时出现.这时空气内尘埃少而充满小水滴,天空的一边因为仍有雨云而较暗.而观察者头上或背后已没有云的遮挡而可见阳光,这样彩虹便会较容易被看到.另一个经常可见到彩虹的地方是瀑布附近.在晴朗的天气下背对阳光在空中洒水或喷洒水雾,亦可以人工制造彩虹.晚虹是一种罕见的现象,在月光强烈的晚上可能出现.由于人类视觉在晚间低光线的情况下难以分办颜色,故此晚虹看起来好像是全白色.原理 造成彩虹的光学原理彩虹是因为阳光射到空中接近圆型的小水滴,造成色散及反射而成.阳光射入水滴时会同时以不同角度入射,在水滴内亦以不同的角度反射.当中以40至42度的反射最为强烈,造成我们所见到的彩虹.造成这种反射时,阳光进入水滴,先折射一次,然后在水滴的背面反射,最后离开水滴时再折射一次.因为水对光有色散的作用,不同波长的光的折射率有所不同,蓝光的折射角度比红光大.由于光在水滴内被反射,所以观察者看见的光谱是倒过来,红光在最上方,其他颜色在下.The rainbow is an optical phenomenon of weather. When the sunlight to the raindrop in the midair, the light is refracted and reflected, in the sky formed arch of the colors of the spectrum. The colours of the rainbow colors what is which seven different argument, China"s most popular argument is (from outside to inside): red, orange, yellow, green, cyan, blue, purple. Western argument is: red, orange, yellow, green, blue, indigo, indigo, violet, source to the scientist Newton decomposition seven colors after the name.Actually as long as there is water in the air, and sunshine are observed behind with low angle radiation may produce rainbow phenomena can be observed. When rainbow most often in the afternoon, after the rain just turn sunny. Then in the air less dust and full of small water droplets, side of the sky because there is still rain clouds and darker. And observe the head or behind has not cloud the occlusion and the sun can be seen, so rainbow will more easily be seen. Another often see rainbows is near the waterfall. In fine weather back of sunshine in the air spray or spray mist can also be manufactured rainbow.Late rainbow is a rare phenomenon, in the evening of a strong moonlight may appear. Due to human vision in the evening low light situation is difficult to distinguish the color, so the night rainbow looks like all white.principleThe optical principle of rainbow is caused by sunlight because air droplets close to circular, resulting in dispersion and reflection made. The sunlight will also drop at different incident angles, the drop in at different angles to reflection. Reflection 40 to 42 degrees is most strong, cause we see rainbow. The reflection of sunlight, into the water, the first index once, and then in the back of the reflection of water droplets, the last to leave the water again when the refraction at a time. Because the water dispersion effect of light refraction, different wavelengths of light refraction angle rate of different blue light than red light is due to Everbright. Reflection on the drop, so to see the spectral observation is reversed, the red light at the top of other colours.

出现在什么地方

My home town is a beautiful place. It stands beside a wide river and is rich in fish and rice. But in the old days it was a poor and backward little town. Many people had no work. They lived a hard life. In 1949 my hometown was liberated. Since then great changes have taken place there. The streets have been widened. Factories, schools, hospitals, cinemas and theatres have sprung up one after another. The life of the people is greatly improved. I love my hometown. All the more I love its people. They are working hard so as to make it still richer and more beautiful.

Fabrics and garments may be labeled waterproof, water-repellent, weather-resistant or some combination of these. But what does it all mean?WaterproofA waterproof fabric is completely impermeable to water.(1) Since all the pores are closed, these fabrics are also impermeable to air and can become hot and uncomfortable as apparel. A vinyl raincoat is an example of a waterproof garment. The wearer remains dry since rain stays outside the coat; it can not soak into or through the fabric. Waterproofness is easy to determine either water can get in or it can not.Water RepellentWater repellence and water resistance introduce a lot more uncertainty. Water repellency is the resistance to wetting; water resistance is the resistance to wetting and water penetration.(2) Different fabrics resist wetting (absorbing water) to different degrees and the AATCC Technical Manual includes two methods for determining water repellency. AATCC Test Method (TM) 22, Water Repellency: Spray Test calls for a visual evaluation of the wetting pattern after the fabric is sprayed with water. Manufacturers and retailers must agree on an acceptable level of repellency based on the end-use of each fabric. A rating of 80-90 (on a scale of 0-100) is generally acceptable for unlaundered samples intended for use as water-repellent outerwear.(3) Water repellency tests measure the amount of water that soaks into the fabric, not the amount that soaks through.Intended mainly to measure the water-repellent efficacy of finishes, TM 70, Water Repellency, Tumble Jar Dynamic Absorption Test is not intended to predict rain penetration resistance.(4) Specimens are tumbled in water, weighed, and the wet weight is compared to the dry weight.Water ResistantAATCC TM 35, Water Resistance: Rain Test and TM 42, Water Resistance: Impact Penetration Test use the weight of the water penetrating the fabric as a measure of resistance. Less than 1 g is usually considered acceptable;3 anything over 5 g is reported as > 5 g and indicates failure as a water-resistant fabric.2 The rain test may be performed at different pressures to simulate different intensities of rain and acceptable values for both tests may vary according to end-use.Another measure of water resistance is TM 127, Water Resistance: Hydrostatic Pressure Test. Water is directed at one side of the fabric under increasing pressure and the point at which water droplets appear on the opposite side is recorded. This test differentiates between the water resistance of the fabric and the water repellency of the fiber, yarn, and fabric construction. The degree to which the fibers and yarns resist wetting, combined with the size, shape, and number of pores in the fabric construction, influences the overall penetrability of the fabric.(5)Weather ResistantWeather resistance, the ability of a material to resist degradation of its properties when exposed to climactic conditions,6 is an even more complicated issue. AATCC TM 186, Weather Resistance: UV Light and Moisture Exposure subjects fabrics to artificial weathering through the use of ultraviolet (UV) light, humidity, and/or water spray. Exposed fabrics are compared to control fabrics in terms of color change and breaking or bursting strength. This test is most appropriate for items which will be placed outdoors for extended periods of time. The test method suggests three cycle options based on end-use梘eneral applications (e.g., outdoor furniture fabrics, and tent material), architectural applications where thermal shock may be an issue, and automotive exteriors. The UV and humidity/spray conditions for each application vary slightly. TMs 111, 169, and 192 are similar tests, using different combinations of light and/or water to simulate weathering.So, will your fabric keep you dry?Waterproof fabric will protect you from rain, but will eventually make you hot and sweaty. A water-repellent fabric will probably keep you dry if you are out in the rain for just a few minutes. Water-resistant fabrics may also keep you dry temporarily and they will be more breathable than waterproof fabrics, but water will eventually soak in, making the fabric heavy and wet. While a weather-resistant fabric makes no promise to keep you dry, it will continue to look and perform as it was intended even after prolonged exposure to sun and rain.References1.
