商务书信的格式 　　美观整洁的书信格式会给收信人留下深刻的印象，那么商务书信的整体格式是怎样的?下面我就为大家细细说来吧! 　　一、信 头 　　在信和传真中，信头所占页面一般不超过三分之一。 　　发信人地址 　　一般来说，商业书信的首页都使用印有公司抬头的信笺，抬头上标明公司名称、地址、电话和传真号码。传真也一样，信笺上印有抬头，并采用固定的信头格式。 传真发信人的地址位于传真纸页首固定的信头格式内。 　　发信日期 　　日期的书写有以下两种模式：“12 June 1998”[日-月-年]或“June 12, 1998”[月-日-年] 日期不能缩写，序数词不能使用缩写形式，月份也不能缩写。 　　收信人地址 　　收信人地址包括收信的全名和职衔，以及公司的全称和地址。礼貌性的称呼要使用得当。 传真中收信人地址一般打在信头格式相应的.空格内。 　　指定收信人姓名 　　在商业书信和传真中，指定收信人姓名这一栏现已不常用。收信人地址的首行已经写明收信人姓名，因而不一定需要专门指定收信人姓名这一栏。 如果要使用指定收信人姓名这一栏，就要从页面左边空白处写起，在收信人地址下面空两行。 　　称 呼 　　商业信件和传真常用以下方式开头： 　　1、Dear Mr/Mrs/Miss/Ms Wang(表示写信人知道收信人的姓名和性别); 　　2、Dear Sir或Dear Madam(表示写给一位有具体职衔的人，如Sales Manager,Chief Accountant等，而且写信人知道对方的性别); 　　3、Dear Sir or Madam(表示写给一位有具体职衔而写信人又不知其性别的人); 　　4、Dear Sirs (表示写给一家公司，没有明确的收信人)。 　　称呼中的第一个单词和其他所有名词的第一个字母均须大写。 　　事 由 　　写明事由可以使收信人对信件或传真的内容一目了然。 　　二、信 文 　　全齐头式(full-blocked)书信，每个段落都从左边空白处开始写起，右边空白处必须尽量对齐，不能把单词断开。 　　在齐头式书信或传真中，信文也是从左边空白处开始写起，在事由下面空一行。 　　三、信 尾 　　传真的信尾一般都很简短(通常只有结尾敬辞和署名)，而书信的信尾内容则相对较长。 　　结尾敬辞 　　一般来说，书信和传真结尾敬辞都使用“Yours sincerely”或“Yours faithfully”。称呼为“Dear Mr/Mrs/Miss/Ms…”时结尾用“Yours sincerely”。称呼为“ Dear Sir/Sir or Madam/Sirs”时结尾则用“Yours faithfully”。 　　信末签名 　　写信人既可代表本人签名，也可代表公司签名。如： 　　Yours faithfully 　　For precision Airconditioning Co (Pte) Ltd 　　Yvonne Chong 　　Ms Yvonne Chong 　　Regional Sales Manager (Singapore) 　　信末签名位于左边空白处。在结尾敬辞或公司名称下面留出三行签名的位置，然后再打上写信的姓名、职衔及/或部门。 　　口述者/打字员姓名缩写 　　下面表中是信函或传真的口述者和打字员的姓名缩写。 　　口述员 　　　　　　打字员 　　　　　　姓名缩写 　　- 　　　　　　　　Sim Loo　　　　　　 Lee sll 　　Cheng Fook Jam 　　Chan Chuen Fye　　 CFJ/ccf 　　Chew Yit Lin Chin 　　Kein Hoong Chew　 Yit Lin/ckh 　　Grahame T Bilbow　　 Foo Tuan Seik 　　　GTBilbow:fts 　　Goh Bee Hua　　　　　 Han Swee Lean　　 GBH:HSL 　　附 件 　　如果信件或传真还附有其他文件，就必须在文中注明。附件说明通常位于口述者/打字 　　员姓名缩写之后。可以采用以下几种方法： 　　·Estimate enclosed 　　·2 Enc./Enclosuree 2 　　·Enclosure 　　·Enclosures: 　　1. 2000 Price list 　　2. Catalogue 　　抄 送 　　如果除主要收信人之外，信件或传真还需抄送第三者时，通常用“cc”表示，“cc”即“carbon copy”(复写本;副本)。有时，如果发信人不想让收信人知道信件或传真还要抄送给别人，就用“bcc”(“blind carbon copy”无信头副本)代替“cc”，标注在不发给收信人的影印件的下方。 　　附 笔 　　商业信函或传真中的“附笔”(缩写为“PS”)用于补充本人的说明。“附笔”位于左边空白齐头处，在“附近”或“抄送”等说明之下空一行。 页码说明 　　商业信函如果超过一页，随后的各页可以在页首加注说明收信人姓名、页码及日期。如： 　　Mrs. H Itakura 　　Page 2 　　14 June 200- 　　在商业信函中，页码有时位于距页顶一英寸的左边空白处，与信文之间空两行。 　　信 封 　　信封显然只适用于商业信件。信封上收信人地址的格式必须与内文的写法一致，即齐头式，单行间隔。收信人姓名位于收信人地址上方，中间空两行。也可以在收信人地址的第一行中直接写上收信人的姓名和职衔。 　　传真格式 　　传真的首页一般都印有现成的信头格式，只需填入写信人和收信人的姓名、地址、传真号码、页数和日期等内容即可。 　　在商业信函中，宽式标点比严标点更为常用。 　　使用严式标点意味着客户地址的每一行结尾都要加逗号，每个缩写词(包括客户姓名的首字母缩写)后面都要加点号(如Mr., Co., Ltd., St., Rd.等，又如Mr. J. R. Liu)。 　　拓展知识： 　　商务书信布局礼仪 　　正排式或垂直式或齐头式（BlockedForm）。 　　这种排列的要领在于每个要素都从左边开始排列，每一行都不向右缩入，因而整封信的左边成一垂直线右边参差不齐。这种形式虽然打字时方便省事，不需考虑左边缩入，但不匀称美观，所以使用它的人也不很多。 ③改良式或混排式（ModifiedForm）。 　　这种排列集上述两种形式之所长，信头、结束语、签名和发信人姓名排在右边，封内地址和称呼排在左边，但每个要素分行时每行都不向右缩入；正文每段开始缩入五个英文字母，而段与段之间可不空行。这种形式兼顾及方便省事与匀称美观，因此，它是目前极为流行的英文书信范式。 　　注意事项 　　①因为手写有时难免不好辨认，所以英文书信最好是打印。 　　②信封的书写一般是收信人名址写在信封正面的中央而发信人名址可写在正面的左上方或者信封的背面，书写形式应与信内风格一致。 　　③书信的折叠也应有讲究 ;

根据IEC60309标准，工业用插头插座连接器电流等级：16、32、63、125......125A以上规格没有尺寸互换性要求。防护等级一般采用：IP22（防滴）、IP44（防溅）、IP56（防浪）、IP67（水密），中文描述仅供参考。 防护等级标准对IP××有详细定义，如：GB 4208-2008 外壳防护等级(IP代码)等效IEC 60529：2001IEC 60529 CORR 3-2009 Degrees of Protection Provided by Enclosures (IP Code) Degres De Protection Procures Par Les Enveloppes (Code IP) Edition 2.1

看你说的在那个方面了，比如食品方面：所谓的工业级，农业级，食品级，试剂纯，分析纯等等只是根据用途不同来划分的例如工业级是在工艺生产过程中使用的,具体含量标准是根据产品属性决定的. 农业级和食品级分别是分别用在农业和食品行业的,其他也是一样 试剂纯，分析纯一般用在化验室在电子产品方面：有商用级、工业级和军用级产品,比如电子的工业级标准是主要参照的标准为中国国家标准GB 4208-93《外壳防护等级(IP代码)》、IEC标准(IEC 60329-2001)《Degrees of protection provided by enclosures (IP Code)》或Nema 250-2003《Enclosures for Electrical Equipment (1000 Volts Maximum)》。主要是不同的标准(带有权威的定义)加国家标准，比如XX产品符合GJB（国军标）什么什么，MIL（美军标）什么什么的。一般来说，军用级最高，工业级次之，然后是商业级，最后是民用级。以电子电源为例：军用级电源，要求很严，比如对防水，防火，防摔、抗电磁等等都有要求；工业级电源，就在没有军用电源那边严格。但对防水、防火有一定要求；商业级电源，要低于工业级电源的防水和防火的要求；民用电源，就是一般我们用的电源，不是很严的要求，但是也有一定在要求，这些要求是分等级的，等级的化分是根据电源的质量、要求及所用途来分类的！

prefaceIs the important basis of the mould manufacturing assembly. No high levels of mould, no high level of industrial products. Mould technology is the measure of a national product manufacture level of important symbol.Mold is able to produce a has certain requirements of the shape and size of the parts of a production tools. Be also usually people say mold, such as television, telephone enclosures, plastic, and other commodities, is the plastic heating software note into a mold cooling molding production comes out. Steaming pot of metal plate is by with mold pressed into such a shape. Any goods are in out of the mould manufacturing. Can say no without the mold the production of the products. So how do out of the mold? First of all it by mold design personnel according to product (parts) the use requirement, the die structure designed, draw drawing again by technical workers according to the drawings by all kinds of mechanical processing requirements (such as lathe, planer, milling machine, grinder, edm, line cutting) to each of the parts in the mold, the assembly and debugging, until can produce qualified products, so tool to master a comprehensive range of high knowledge and skills, die doing good, good quality of product, mould reasonable structure, high production efficiency. The factory efficiency good.Mould industry is the foundation of industrial industries, industrial every field of widely used mold. In electronics, automobiles, electric motors, electric appliances, instruments and meters, home appliances and products such as communication, 60% to 8% of a 0 parts depends on that of die forming. With mold production parts shown by the high precision, high complexity, high consistency, high productivity and low consumption, is other processing manufacturing method can match. Mold is "benefit amplifier", in the mold production of the final product value, is often die own value on a few times, one hundred times. Mold production technology of level, to a large extent, on the quality of products and the benefits and new product development ability, and has become the measure of a national product manufacture level of important sign [3]. Mould as the basis of industrial production technology and equipment, the national economy in played an important role. In the past 10 years, mould CAD technology develops very quickly, application range widening. Mould CAD technology to die design and manufacturing provides an efficient, economy and rapid method, greatly promoted the mould quality, shorten the die design and manufacture period, lower the cost of the die. At home and abroad and have been many mould CAD system, the system although has strong analysis ability and graphics processing power, can provide interactive design. But in these systems, mould design process mainly adopts the man-machine interactive way, most of the design is depend on the design experience of the operator, the computer is just for some rules matching, and calculating work, and for previous success of the mould design can"t effective use of, cause mould design cycle is very long, the cost is higher, the development of efficiency is very low.Mold is the foundation of industrial production technology and equipment, known as "the mother of industrial". 75% of the rough machining parts, 50% of industrial products finish machining parts are made by the molds, most of the plastic products also by molds. As the foundation of the national economy industry, mould involving machinery, automobile, light industry, electronic industry, chemical industry, metallurgy, building materials, and other industries, application scope is very extensive.

问题一：工业级是什么意思 工业级，农业级，食品级，试剂纯，分析纯等等是根据用途不同来划分的。 工业级是在工艺生产过程中使用的,具体含量标准是根据产品属性决定的.。 一般来说，军用级最高，工业级次之，然后是商业级，最后是民用级。 以电子电源为例： 军用级电源，要求很严，比如对防水，防火，防摔、抗电磁等等都有要求；工业级电源，就在没有军用电源那边严格。但对防水、防火有一定要求； 商业级电源，要低于工业级电源的防水和防火的要求； 民用电源，就是一般我们用的电源，不是很严的要求，但是也有一定在要求， 这些要求是分等级的，等级的化分是根据电源的质量、要求及所用途来分类的！ 工作基准试剂（国标无简写标记，用汉语注明，绿色标签）：作为基准物质，标定标准溶液。 优级纯（GR，绿色标签）：主成分含量很高、纯度很高，适用于精确分析和研究工作，有的可作为基准物质。 分析纯（AR，红色标签）：主成分含量很高、纯度较高，干扰杂质很低，适用于工业分析及化学实验。这个是一般实验室用的最多的等级。 化学纯（CP，蓝色标签）：主成分含量高、纯度较高，存在干扰杂质，适用于化学实验和合成制备。 实验试剂（LR，黄色标签）：主成分含量高，纯度较差，杂质含量不做选择，只适用于一般化学实验和合成制备。问题二：什么叫做工业级的产品？ 看你说的在那个方面了，比如食品方面： 所谓的工业级，农业级，食品级，试剂纯，分析纯等等只是根据用途不同来划分的 例如工业级是在工艺生产过程中使用的,具体含量标准是根据产品属性决定的. 农业级和食品级分别是分别用在农业和食品行业的,其他也是一样 试剂纯，分析纯一般用在化验室 在电子产品方面： 有商用级、工业级和军用级产品, 比如电子的工业级标准是主要参照的标准为中国国家标准GB 4208-93《外壳防护等级(IP代码)》、IEC标准(IEC 60329-2001)《Degrees of protection provided by enclosures (IP Code)》或Nema 250-2003《Enclosures for Electrical Equipment (1000 Volts Maximum)》。 主要是不同的标准(带有权威的定义)加国家标准，比如XX产品符合GJB（国军标）什么什么，MIL（美军标）什么什么的。 一般来说，军用级最高，工业级次之，然后是商业级，最后是民用级。 以电子电源为例： 军用级电源，要求很严，比如对防水，防火，防摔、抗电磁等等都有要攻； 工业级电源，就在没有军用电源那边严格。但对防水、防火有一定要求； 商业级电源，要低于工业级电源的防水和防火的要求； 民用电源，就是一般我们用的电源，不是很严的要求，但是也有一定在要求， 这些要求是分等级的，等级的化分是根据电源的质量、要求及所用途来分类的！问题三：工业级是什么呀 工业级是电子设备的常用分级，一般电子设备被分为商用 工业 军工等等分级。工业级满足一般工业现场的环境气氛。如果用于恶劣环境将不适用。用于商业环境又成本偏高。 问题四：工业级是什么意思 工业级，农业级，食品级，试剂纯，分析纯等等是根据用途不同来划分的。 工业级是在工艺生产过程中使用的,具体含量标准是根据产品属性决定的.。 一般来说，军用级最高，工业级次之，然后是商业级，最后是民用级。 以电子电源为例： 军用级电源，要求很严，比如对防水，防火，防摔、抗电磁等等都有要求； 工业级电源，就在没有军用电源那边严格。但对防水、防火有一定要求； 商业级电源，要低于工业级电源的防水和防火的要求； 民用电源，就是一般我们用的电源，不是很严的要求，但是也有一定在要求， 这些要求是分等级的，等级的化分是根据电源的质量、要求及所用途来分类的！ 工作基准试剂（国标无简写标记，用汉语注明，绿色标签）：作为基准物质，标定标准溶液。 优级纯（GR，绿色标签）：主成分含量很高、纯度很高，适用于精确分析和研究工作，有的可作为基准物质。 分析纯（AR，红色标签）：主成分含量很高、纯度较高，干扰杂质很低，适用于工业分析及化学实验。这个是一般实验室用的最多的等级。 化学纯（CP，蓝色标签）：主成分含量高、纯度较高，存在干扰杂质，适用于化学实验和合成制备。 实验试剂（LR，黄色标签）：主成分含量高，纯度较差，杂质含量不做选择，只适用于一般化学实验和合成制备。问题五：五金工具里所说的工业级什么意思 工业级工具最初由开拓工具国际集团老总吴献法提出。 一个普通家庭一把扳手可能一辈子都用不坏，但是如果放到汽车修理店呢?每天成百上千次的反复使用，你无法想像，一辈子用不坏的扳手半天就不能工作了，这时候就要求有一种能够经得起反复考验的工具，工业级工具应运而生，工业级工具所使用的材料、制造工艺与普通工具截然不同，不光这样，每一款工业级工具都要经过反复测试，每一把工业级工具都要经过仔细检查才能进入市场。问题六：什么叫工业级专业空调 工业级别空调控制环境的温度湿度精度没有精密空调高，工业级别意义上的空调环境。 工业空调有大金，精密空调有艾默生，stulz，APC、RC等。问题七：触摸屏工业级是什么意思？三防主要指什么？ 工业现场的防护等级一般指防水和防尘，第三防好像没有特指过， 不过有客户提出过，好像是防油问题八：什么是工业级白砂糖 工业糖指的是原糖。 工业糖执行的标准是《GB 15108-2006 原糖》。 原糖含有一定量的杂质，色泽比白糖深，含有相对较多的水份和糖蜜，微生物含量也比白砂糖为高。原糖只能用作工业生产(主要用来生产白砂糖或绵白糖)，不能直接食用，不能直接添加到食品中作为原料使用。 绵白糖是从甜菜里提取的，砂糖是从甘蔗里提取的，一般绵白糖的产地是北方，而砂糖是南方。 绵白糖的甜度要高于砂糖，用途跟砂糖没有太大区别，我一般不喜欢用绵白糖，因为保存很困难，又要防潮还要防干结~，取用的时候也粘粘乎乎的弄不清爽工业白糖和食用白糖没有区别，都是白砂糖。 白糖主要有白砂糖和绵白糖两种。颜色洁白、颗粒如砂者，叫白砂糖;颜色洁白、粒细而软，入口易化者，叫棉白糖。 白砂糖是蔗糖的结晶体，纯度一般在99.8%以上，从化学角度看，这是很纯的物质了。白砂糖具有纯正的蔗糖甜味，除直接食用外，也是工业用糖的主要品种。 绵白糖是细小的蔗糖晶粒被一层转化糖浆包裹而成的，其纯度与白砂糖相当。转化糖在这里起着变软、增香、助甜的作用。这是因为转化糖具有蜂蜜般的清香味(蜂蜜的主要组分就是转化糖)其甜度又大于蔗糖(以蔗糖的甜度为1，则转化的糖甜度为1.2)，转化糖的较强的吸水能力保持了糖粒的锦软，所以绵白糖的口感优于白砂糖。问题九：家用级、商业级、工业级产品的区别？ 国家标准对有些产品分军用、民用（包括工业用），当然军用的标准更高。 企业自称的家用级、商用级、工业级、企业级，都是企业自定的质量等级划分，没有统一规定。一般来说，商用级、工业级、企业级的质量标准更高些，这是因为在商用、工业用、企业用的情况下，使用条件更差，使用时间更长，所以对质量要求也更高。 举例来说，榨汁机在家用情况下，一天用不了几次，每次时间也不长，可是在饮品店的商用情况中，往往是好几个小时的频繁使用，显然，商用级的榨汁机应该有更高的质量标准。

轿厢是电梯用以承载和运送人员和物资的箱形空间。轿厢一般由轿底、轿壁、轿顶、轿门等主要部件构成，其内部净高度至少应为2m。轿厢架（轿架 car frame）是轿厢的承载结构，轿厢的负荷（自重和载重）由它传递到曳引钢丝绳。当安全钳动作或蹲底撞击缓冲器时，还要承受由此产生的反作用力，因此轿厢架要有足够的强度。轿厢架一般由上梁、立柱、底梁和拉条（调节轿底水平度，防止底板倾翘）等组成。轿厢体是形成轿厢空间的封闭围壁，除必要的出入口和通风孔外不得有其他开口（少部分国家要求轿顶开设安全窗），轿厢体由不易燃和不产生有害气体和烟雾的材料组成。为了乘员的安全和舒适，轿厢入口和内部的净高度不得小于2米。为防止乘员过多而引起超载，轿厢的有效面积必须予以限制。具体可参见GB7588-2003对额定载重量和轿厢最大有效面积的对应规定。在乘客电梯中为了保证不会过份拥挤，标准还规定了轿厢的最小有效面积。轿厢体一般由轿底板（轿底 car platform;platform）、轿厢壁（轿壁 car enclosures;car walls）、轿厢顶（轿顶 car roof）。厢内装置一般有操纵箱（轿内的操纵装置）、通风装置、照明、停电应急照明、报警和通信装置。称量装置一般设在轿底，也有少数设在轿顶的上梁或者绳头板上。基本结构是在底梁上安装若干个微动开关（触点）或重量传感器，当置于弹性胶垫上的活络轿厢由于载荷增加向下位移时，触动微动开关发出信号，或由传感器发出与载荷相对应的连续信号。最基本的一个开关，在超载（超过额定载荷10%）时动作，使电梯门不能关闭，电梯也不能起动，同时发出声响和灯光信号（有些无灯光信号）。所以也称超载开关。轿厢分类编辑由于各类电梯的用途不同,因此其轿厢结构也不一样.1.客梯轿厢2.住宅梯轿厢3.医用(病床)梯轿厢4.货梯轿厢5.杂物梯轿厢6.观光梯轿厢7.汽车梯轿厢8.矿井梯轿厢9.冷冻电梯轿厢10.船舶梯轿厢

Sure, here"s a short English composition about a visit to the zoo:Last weekend, I went to the zoo with my family. We were excited to see various animals from around the world. As we entered, the vibrant colors and sounds filled the air. We observed lions, tigers, and bears in their enclosures, marveling at their strength and beauty. The monkeys swung from tree to tree, entertaining us with their playful antics. The giraffes gracefully stretched their long necks to reach the leaves. We enjoyed the educational shows and learned interesting facts about different species. It was a memorable day at the zoo, creating lasting memories for all of us.请注意，这篇作文是大约六句话的简短作文，描述了一次去动物园的经历。使用了一般过去时态和多样的动物词汇。文章流畅、简洁，以吸引读者的注意力并传达了作者的观点。

《Finger Prints》（Francis Galton）电子书网盘下载免费在线阅读链接: https://pan.baidu.com/s/1UPxOrKlnLiwoV3pnS7a7Ag 提取码: mkhx书名：Finger Prints作者：Francis Galton出版社：Prometheus Books出版年份：2006-6页数：191内容简介：Despite the increasing use of DNA evidence and other sophisticated forensic techniques in crime solving, fingerprints still serve as an indispensable tool of modern-day criminal investigation. This fascinating book, originally published in 1892, represents the first thorough investigation of this anatomical peculiarity and its application in establishing individual identity for use in law enforcement. Sir Francis Galton, a cousin of Charles Darwin and a member of the Royal Geographical Society, had already made a reputation for himself as an explorer of Africa and the founder of the new field of eugenics when he turned his attention to the subject of fingerprints. Through extensive research at his "anthropometric laboratory", Galton laid out an elementary system of classifying fingerprints based on observed patterns of arches, loops, and whorls. Using meticulous drawings as well as photographs of ink prints, he showed that "the numerous bifurcations, origins, islands, and enclosures in the ridges that compose the pattern, are proved to be almost beyond change." Thus, he established a sure method of individual identification. Galton"s system was later modified by Sir Edward R Henry, who became chief of police in London. In 1901, Scotland Yard officially adopted the Galton-Henry system of fingerprinting. Today, it is the most widely used system of fingerprint classification in the world. This classic work will make a welcome addition to the libraries of historians, criminologists, and fans of true crime and forensic science.

At the zoo, the air is filled with excitement and anticipation. Visitors eagerly gather, their eyes filled with wonder and curiosity. Colorful birds soar through the sky, their vibrant feathers painting a breathtaking picture against the backdrop of lush greenery. Majestic lions roam their enclosures with regal grace, their powerful presence commanding attention. Laughter fills the air as children watch playful monkeys swinging from branch to branch, creating a lively scene that captivates the hearts of all who visit the zoo.

Tourism in Singapore is a major industry and attracts millions of tourists each year.[1] A lot of its cultural attraction can be attributed to its cultural diversity that reflects its colonial history and Chinese, Malay, Indian and Arab ethnicities. It is also environmentally friendly, and maintains natural and heritage conservation programs. As English is one of its numerous official languages, it is generally easier for tourists to understand when speaking to the local population of the country, for example, when shopping. Transport in Singapore exhaustively covers most, if not all public venues in Singapore, which increases convenience for tourists. This includes the well-known Mass Rapid Transit (MRT) system.The Orchard Road district, which is dominated by multi-storey shopping centres and hotels, can be considered the centre of tourism in Singapore. Other popular tourist attractions include the Singapore Zoo and its Night Safari, which allows people to explore Asian, African and American habitats at night without any visible barriers between guests and the wild animals. The Singapore Zoo has embraced the "open zoo" concept whereby animals are kept in enclosures, separated from visitors by hidden dry or wet moats, instead of caging the animals. Jurong Bird Park is another zoological garden centred around birds, which is dedicated towards exposing the public to as much species and varieties of birds from around the world as possible, including a flock of one thousand flamingos. The tourist island of Sentosa, which attracts more than 5 million visitors a year, is located in the south of Singapore, consists of about 20-30 landmarks, such as Fort Siloso, which was built as a fortress to defend against the Japanese during World War II. Guns from the World War II era can be seen at Fort Siloso, from a mini-sized to a 16 pound (7 kg) gun. Recently, the island has built the Carlsberg Sky Tower, which allows visitors to view the whole of Sentosa, as well as the Sentosa Luge, a small one- or two-person sled on which one sleighs supine and feet-first. Steering is done by shifting the weight or pulling straps attached to the sled"s runners. Singapore will have two integrated resorts with casinos in 2010, one at Marina Bay and the other at Sentosa which the government announced during a parliament session on April 18, 2005.There are various shopping belts in Singapore, Marina Bay, Bugis Street, Chinatown, Geylang Serai, Kampong Gelam & Arab Street, Little India, North Bridge Road, Orchard Road, Riverside, Shenton Way & Raffles Place and The Suburbs.Singapore seeks to be the business hub of Southeast Asia and has an expansive shopping precinct located in the Orchard Road district. Many multistorey shopping centres are located at Orchard Road; the area also has many hotels, and it"s the main tourism centre of Singapore, other than the Downtown Core. The local populace also use Orchard Road for shopping extensively.Other than Orchard Road, Singapore"s largest shopping centre, VivoCity, has also attracted millions of people since its opening in 2006.[13]To further encourage tourists to shop at Singapore, the Singapore Tourism Board and various organizers organize the Great Singapore Sale yearly. Shoppers can enjoy great discounts and bargains at participating outlets. The Singapore Tourism Board introduced "Late Night Shopping" in 2007.[14] Tourists can catch "Late Night Shopping" on Orchard Road up till 11pm every Saturday and enjoy special deals or promotions by participating retailers.Singapore is a haven for the arts all year round. Its dynamic arts scene is richly influenced by their indigenous Malay culture, the heritage of Chinese and Indian migrants, as well as the cityu2019s international outlook. As new contemporary forms evolve, traditional art forms are simultaneously being preserved to create an arts culture that is uniquely Singapore.The Art Districts in Singapore include Central Arts Districts, Chinatown Arts Belt, Dempsey and Tanglin, Little India, and Riverside. The are also various art museums in Singapore like the Asian Civilisations Museums at Empress Place and Old Tao Nan School, Singapore Art Museum, and NUS Museums.Many of Singapore"s performing arts venues and institutions are more than just performance locations u2013 they are architectural marvels in their own right. These venues include the Singapore Repertory Theatre, Esplanade - Theatres on the Bay, The Substation and the University Cultural Centre.Sentosa is a relatively large island of Singapore located to its south. Along with a beachfront resort, the island"s tourist attractions include Fort Siloso, its historical museum, the Underwater World aquarium and the Carlsberg Sky Tower. Singapore will also be building two casinos (integrated resorts), one on Marina Bay and one on Sentosa. Singapore has a variety of parks and projects which often feature its natural tropical environment.The Singapore Zoo and Night Safari, allows people to explore Asian, African and South American habitats at night, without any visible barriers between guests and the wild animals.Singapore has its Singapore Botanical Gardens open to the public that is 52 hectares large, and includes the National Orchid collection with over 3000 types of orchids growing.Recently the government has also been promoting the Sungei Buloh Wetlands Reserve as a quiet getaway from the stress of modern life.The Bukit Timah Nature Reserve is an extensive nature reserve which covers much of the Bukit Timah Hill, and is the only remaining place where primary rainforest still exists on the island.The Jurong BirdPark includes extensive specimens of exotic bird life from around the world, including a flock of one thousand flamingos.Pulau Ubin, an island offshore Singapore, is slowly becoming a popular tourist spot. The nature wildlife there is left undisturbed.Singapore is among the top five countries in the world for nightlife, fine dining and shopping.[15] Some popular nightspots in Singapore include:Boat Quay is a historical quay in Singapore which is situated upstream from the mouth of the Singapore River. Shophouses on it have been carefully conserved and now house various bars, pubs and restaurants.Clarke Quay is a historical riverside quay and a buzzing party central in Singapore, and is situated even further upstream from the mouth of the Singapore River than Boat Quay is. Presently, five blocks of restored warehouses house various restaurants and shops such as antique shops. There are also moored Chinese junks (tongkangs) that have been refurbished into floating pubs and restaurants. Crazy Horse Paris opened their third cabaret show worldwide in Clarke Quay in December 2005, but ended operations in February 2007 owing to poor business. The Ministry of Sound opened at Clarke Quay in December 2005 and is one of the most popular nightclubs in the city currently.Clarke Quay also boasts more than 50 eateries offering over 20 different types of cuisine, and more than 20 bars, clubs and pubs. Some of the world"s best pubs are located in Clarke Quay.

商务英语写作书信的几种格式 　　为了帮助大家更好地备考BEC考试，以下是我整理的商务英语写作书信的几种格式，希望对大家有所帮助。 　　1. 全齐头式(Full-blocked)：这种格式的信函各部分内容都从左边空白处写起，用起来方便省事，是现今常用的格式之一。 　　2. 齐头式(Blocked)：这种格式与全齐头式相似，只是有些内容不是从空白处写起。结尾敬辞、信末签名、写信人姓名和职衔都从中间写起。日期可以从中间起行，也可以靠右对齐。 　　3. 半齐头式(semi-blocked)：这种格式与齐头式雷同。不同的是，半齐头式的每个段落缩进五或十个英文字母;结尾敬辞、信末签名、写信人姓名和职衔从中间写起。 　　4. 方齐头式(square-blocked)：这种格式也类似于全齐头式。不同的是，它的日期靠右对齐，和收信人地址在同一行。这种格式平整见方，外观漂亮。 　　5. 简化式(simplified)：简化时式和全齐头式相比，有几个主要的区别：首先，简化式没有称呼和结尾敬语，收信人姓名必须在信文内的某个地方出现。其次，事由和写信人姓名必须大写。最后，列表要缩进五个英文字母空位，如果加有序号就不必缩进。 　　商务英语书信的格式与结构 　　我国实行对外开放以来，对外贸易得到迅速发展。WTO的成功加入，使我国的对外贸易事业有了突破和发展。作为对外贸易中的一种基本的通讯联络方式，商务英语书信也得到广泛应用。对于外贸专业的学生以及从事对外贸易的工作者来说，熟练掌握商务英语书信的格式与结构并加以应用，是不可或缺的一项技能。 　　商务英语书信有自己独特的格式与结构。虽然现在的人们喜欢标新立异，喜欢以一种更随意、更友好的方式进行交往，但是，为了避免寄信方和收信方之间由于格式、结构的不统一而引起的混乱，以及由此而带来的查找不便、使双方花费不必要的时间，所以，最安全、最有效的方法就是遵循国际上常用的、约定俗成的格式与结构。一旦选定一种格式与结构，最好是坚持使用，不能想改就改，想换就换，否则就会给对方一种不稳定、不踏实的感觉，会引起一些意想不到的麻烦，有可能最后导致交易的失败。 　　一般来说，现在使用的商务英语书信的格式主要有两种:传统的`缩头式(the conventionalindented form) 和现代的齐头式(the modern blocked form) 。 　　根据英国传统做法，缩头式要在信文每一段缩进五或六个字母的空间，有时可能会缩进更多。现在，齐头式在商务英语书信中使用得非常普遍。它的突出特点就是所有信的内容都从信纸的左边开始，段落与段落之间要比缩头式多空出两到三行，以便于区分。这种格式被称作齐头式(the fullblocked form) 。但是，有时把日期放在信纸的左边会给查找带来不便，所以，人们使用了一种改良的齐头式(the modifiedblocked form) ，即把日期放在右边，而把其他内容放在左边。 　　一般来说，我们通常使用单行距来布局一封信，这会使我们所写的信有一种紧凑感，但有些人在写短信的时候，更喜欢用双行距。 　　根据个人或公司的喜好，可以选择使用齐头式或缩头式。但不论选择哪一种格式，一般商务英语书信的结构都包括以下几部分内容: 　　(1) 信头(the letter - head) 　　(2) 案号和日期(the reference and date) 　　(3) 封内名称和地址(the inside name and address) 　　(4) 开头称呼语(the salutation) 　　(5) 信文(the message or the body of the letter) 　　(6) 结尾敬语(the complimentary close) 　　(7) 写信人签名或签署(the writer"s signature and designation) 　　(8) 注意事项(the attention line) 　　(9) 事由、标题(the subject line) 　　(10) 经办人代号(the reference notation) 　　(11) 附件(the enclosure) 　　(12) 抄送(the carbon copy notation) 　　(13) 附言(the postscript) 　　在商务英语书信中，上述每一部分内容都有自己固定的位置，包含自己独特的内容，它们是不能随意互换的。 　　信头所包含的是写信人的基本情况，包括他的姓名、地址、电话号码、电传号码以及传真号码甚至E - mail 地址。信头在信纸的最上方，有的公司把信头直接印在所使用的信纸上。质量优良的信纸以及一个整洁、匀称的信头，可以展示一个公司的风采，增强公司的信誉。 　　案号是写信时所给的、以便查询的字母或数字。经常以“Our ref”和“Your ref”来区分。它的位置一般是在信头的右边。而日期在信头以下三行或四行，不管是齐头式还是缩头式，一般把日期放在右端，这可起到行尾的作用，使信看上去更整齐。在商务英语书信中，日期一定要写全，不能用数字的形式，因为美国和英国的日期标示法是不同的。英国的日期标示法是“24th March,2002”， 而美国的日期标示法则是“March24 ,2002”。月、日的后面用逗号，年份后面不用标点。 　　封内名称和地址即收信人的名称和地址，要放在信纸的左上方，在日期以下三行或更多行，这可根据信的长短来定。 　　封内名称和地址要用齐头式，紧靠信纸的左边，这样会使信看上去整齐。 　　开头称呼语是写信人开始信文的礼貌用语，一般商务英语书信中多用Dear Sir ， Dear Sirs 或Gentlemen ，并且独立成行，在封内名称和地址以下三行。在Dear Sir 或Dear Sirs 后面用逗号，而在Gentlemen 后面用冒号。 　　信文是实质性的内容，信文的书写要求是简洁、清晰、礼貌;语法正确，切中要点;段落划分明确，每段集中于一个话题;打印准确，布局要有艺术性，使你的信件看上去赏心悦目。尤其注意页边空栏，它是信文的框架。信文多用单行距，有些短信可用双行距。 　　结尾敬语是信件结束时的一种礼貌用语。它只是一种礼貌用语，在信中没有实际意义，传统使之成为必须，并已成为习惯，所以一直沿用至今。传统的结尾敬语有: Yours faithfully ， Yours truly(多用于美国) 等，也有人用倒装的Faithfullyyours ， Truly yours 等。结尾敬语必须和信文紧连一起，不能分开，更不能把它单独放到另一页。如遇此种情况，则信件必须重新安排、打印。 　　签署是写信人或其所代表公司的名称或标记。公司名称可以打印，而主管人签名则必须是手写，两者都不可用印章代替。这部分在结尾敬语以下三行，大约留出五行或更多的空间。 　　注意事项的习惯用语是:For the attention of 或简单的Attention ，下面一般要加上横线。当信件是写给特定的人或主办部门时，则用此用语。它在开头称呼语以上两行。除齐头式外，可放在信文以上中间。 　　事由或标题在开头称呼语以下两行，下加横线，除齐头式外，一般放在信文以上中间。经常是用一词或简单的几个词来表示信文的主题，让收信人先对所谈内容有所了解。 　　经办人代号在签署以下两行。是打字员名字的首字母缩写，可用小写，也可用大写。 　　附件在经办人代号以下两行。写信人可标示出一个或多个信中所提到的附件。经常使用的形式有: Enclosure ， Enclosures ，Encl. ，Enc. 等。 　　抄送在附件以下两行。抄送有明、暗两种方式。明示的标记为cc ，后面加上收件人或公司的名字，可打印在原件和复印件上。暗示的标记为bcc ，后加收件人或公司的名字，只打印在复印件上，并且只有写信人和收信人知道。 　　附言在抄送以下两行。如写信人想增加些信中忘记提到的内容，可用此方式，但应尽量避免使用。因为它可能会给人一种错觉，即在写信前，你未能很好地安排你的信件。这可能会影响到你的信誉。 　　在上述十三部分内容中，前七部分是每一封商务英语信件所必需包含的内容，而后几部分则是可有可无的。 　　总之，当你书写商务英语书信的时候，必须谨记:选定一种格式，坚持使用，不能变来变去;结构中的内容要安排合理得当，所必需的七部分内容一个都不能少。布局好的信件是双方交易的好的开始。一封布局优雅、端庄匀称的信件，会留给人一种良好的印象，促进双方的进一步往来，直至交易的达成。 ;

什么回答嘛..一楼..哈哈楼主可以说的正式一点吗..?这样不明白很难翻译耶

你发的内容是不是有垃圾邮件特征？我看到有一个Coremail Antispam，这个是Coremail邮件系统的反垃圾邮件系统。

看你说的在那个方面了，比如食品方面：所谓的工业级，农业级，食品级，试剂纯，分析纯等等只是根据用途不同来划分的例如工业级是在工艺生产过程中使用的,具体含量标准是根据产品属性决定的. 农业级和食品级分别是分别用在农业和食品行业的,其他也是一样 试剂纯，分析纯一般用在化验室在电子产品方面：有商用级、工业级和军用级产品,比如电子的工业级标准是主要参照的标准为中国国家标准GB 4208-93《外壳防护等级(IP代码)》、IEC标准(IEC 60329-2001)《Degrees of protection provided by enclosures (IP Code)》或Nema 250-2003《Enclosures for Electrical Equipment (1000 Volts Maximum)》。主要是不同的标准(带有权威的定义)加国家标准，比如XX产品符合GJB（国军标）什么什么，MIL（美军标）什么什么的。一般来说，军用级最高，工业级次之，然后是商业级，最后是民用级。以电子电源为例：军用级电源，要求很严，比如对防水，防火，防摔、抗电磁等等都有要求；工业级电源，就在没有军用电源那边严格。但对防水、防火有一定要求；商业级电源，要低于工业级电源的防水和防火的要求；民用电源，就是一般我们用的电源，不是很严的要求，但是也有一定在要求，这些要求是分等级的，等级的化分是根据电源的质量、要求及所用途来分类的！

GB24906-2010普通照明用50V以上自镇流LED灯安全要求GB/T24907-2010道路照明用LED灯性能要求GB/T24908-2010普通照明用自镇流LED灯性能要求LED灯特点：1、节能.白光LED的能耗仅为白炽灯的1/10，节能灯的1/4.2、长寿.寿命可达10万小时以上,对普通家庭照明可谓"一劳永逸".3、可以工作在高速状态.节能灯如果频繁的启动或关断灯丝就会发黑很快的坏掉，所以更加安全。4、固态封装，属于冷光源类型。所以它很方便运输和安装，可以被装置在任何微型和封闭的设备中，不怕振动，基本上用不着考虑散热。5、led技术正日新月异的在进步，它的发光效率正在取得惊人的突破，价格也在不断的降低。一个白光LED进入家庭的时代正在迅速到来。6、环保，没有汞的有害物质。LED灯泡的组装部件可以非常容易的拆装，不用厂家回收都可以通过其它人回收。7、配光技术使LED点光源扩展为面光源，增大发光面，消除眩光，升华视觉效果，消除视觉疲劳；8、透镜与灯罩一体化设计。透镜同时具备聚光与防护作用，避免了光的重复浪费，让产品更加简洁美观；9、大功率led平面集群封装，及散热器与灯座一体化设计。充分保障了led散热要求及使用寿命，从根本上满足了LED灯具结构及造型的任意设计，极具LED灯具的鲜明特色。10、节能显著。采用超高亮大功率led光源，配合高效率电源，比传统白炽灯节电80%以上，相同功率下亮度是白炽灯的10倍；11、超长寿命50,000小时以上，是传统钨丝灯的50倍以上。LED采用高可靠的先进封装工艺—共晶焊，充分保障LED的超长寿命；12、无频闪。纯直流工作，消除了传统光源频闪引起的视觉疲劳13、绿色环保。不含铅、汞等污染元素，对环境没有任何污染；14、耐冲击，抗雷力强，无紫外线（UV）和红外线（IR）辐射。无灯丝及玻璃外壳，没有传统灯管碎裂问题，对人体无伤害、无辐射。15、低热电压下工作，安全可靠。表面温度≤60℃（环境温度Ta=25℃时）；16、宽电压范围，全球通用LED灯。85V~264VAC全电压范围恒流，保证寿命及亮度不受电压波动影响；17、采用PWM恒流技术，效率高，热量低，恒流精度高；18、降低线路损耗，对电网无污染。功率因数≥0.9，谐波失真≤20%，EMI符合全球指标，降低了供电线路的电能损耗和避免了对电网的高频干扰污染；19、通用标准灯头，可直接替换现有卤素灯、白炽灯、荧光灯；20、发光视效能率可高达80lm/w，多种LED灯色温可选，显色指数高，显色性好；很明显，只要LED灯的成本随led技术的不断提高而降低。节能灯及白炽灯必然会被LED灯具所取代。国家越来越重视照明节能及环保问题，已经在大力推行使用LED灯具了。

（轿架 car frame）是轿厢的承载结构，轿厢的负荷（自重和载重）由它传递到曳引钢丝绳。当安全钳动作或蹲底撞击缓冲器时，还要承受由此产生的反作用力，因此轿厢架要有足够的强度。轿厢架一般由上梁、立柱、底梁和拉条（调节轿底水平度，防止底板倾翘）等组成。 是形成轿厢空间的封闭围壁，除必要的出入口和通风孔外不得有其他开口（少部分国家要求轿顶开设安全窗），轿厢体由不易燃和不产生有害气体和烟雾的材料组成。为了乘员的安全和舒适，轿厢入口和内部的净高度不得小于2米。为防止乘员过多而引起超载，轿厢的有效面积必须予以限制。具体可参见GB7588-2003对额定载重量和轿厢最大有效面积的对应规定。在乘客电梯中为了保证不会过份拥挤，标准还规定了轿厢的最小有效面积。轿厢体一般由轿底板（轿底 car platform;platform）、轿厢壁（轿壁 car enclosures;car walls）、轿厢顶（轿顶 car roof）。 一般设在轿底，也有少数设在轿顶的上梁或者绳头板上。基本结构是在底梁上安装若干个微动开关（触点）或重量传感器，当置于弹性胶垫上的活络轿厢由于载荷增加向下位移时，触动微动开关发出信号，或由传感器发出与载荷相对应的连续信号。最基本的一个开关，在超载（超过额定载荷10%）时动作，使电梯门不能关闭，电梯也不能起动，同时发出声响和灯光信号（有些无灯光信号）。所以也称超载开关。

是小机还是pcserver ，好像有部分硬件没有加电

Last summer, I got a chance to work on a farm during my vacation. Although the work was demanding, it was an amazing and memorable experience.I got up early every morning and went out to the fields for work. The first thing I had to do was check the watering system and ensure that all the plants were properly irrigated. Then I had to take care of the animals. I fed them, cleaned their enclosures and made sure they were healthy. After that, I had to harvest the crops. Picking up fruits and vegetables was hard work, but the satisfaction of seeing a field full of harvested produce was worth the effort.The farm work involved a lot of physical labor and it was challenging at times. However, I learned how to work in a team and the importance of communication with my fellow farm workers. We had to cooperate to ensure that everything was done in time and to standard. Through this, I learnt a valuable lesson about the importance of hard work, discipline and dedication.Working on the farm also made me appreciate the hard work that farmers put into growing our food. It takes a lot of effort to produce fruits and vegetables, and many people take for granted the process involved in bringing food to their tables.In conclusion, working on the farm was a challenging yet rewarding experience. It taught me the value of hard work and dedication, and the importance of cooperation and teamwork. Most importantly, working on the farm gave me an appreciation of the food we eat and the efforts of those who produce it.去年夏天，我有机会在假期时在一家农场工作。虽然这份工作很辛苦，但它是一次美妙而难忘的经历。每天早上我都会早早起床去田地工作。我首先要检查灌溉系统，并确保所有的植物都得到了正确的灌溉。然后我要照顾动物，给它们喂食，清洁它们的围栏并确保它们身体健康。之后，我要收割庄稼。摘取水果和蔬菜是很辛苦的工作，但看到整个田地都堆满了收获的农作物，一切的辛劳都变得值得。农场工作需要很多体力劳动，在某些时候有些挑战性。但是，我学会了如何与团队合作，以及与我的农场同事沟通的重要性。我们必须合作来确保所有的工作都按时完成，做到规范。通过这一过程，我学到了艰苦工作、纪律和奉献的重要性，这是非常宝贵的经验。在农场工作也让我更加珍惜农民种植食物的辛苦工作。种植水果和蔬菜需要付出很多努力，很多人忽略了将食物端到自己餐桌上背后的过程。总之，在农场工作是一次富有挑战性但又非常有收获的经历。它教会了我勤奋工作、奉献精神的价值，以及合作和团队合作的重要性。最重要的是，农场工作让我更加珍惜我们所吃食物的珍贵感和生产者所做出的努力。

假设你是一名导游，请根据提供的信息，用英文向游客介绍一下新加坡。60词左右。Hallo,everyone,wellcome to Singapore!I am (名字),very honoured to be the guide of everybody today.Well,let me introduce Singapore first.Singapore is a small country in Southeast Asia,very close to China.Its enviroment is really good,i think you have already felt---fresh air,light blue and clean sky,transparent and limpid lakes... Its famours landmarks and scenic pots are the Night Safari and Merlion Park which is in Sentosa(圣陶沙,新加坡著名也是主要的旅游景点).OK,l think you are all very excited to visit them,let us go now!请用英文介绍一下新加坡的旅游景点！！谢谢Tourism in Singapore is a major industry and attracts millions of tourists each year.[1] A lot of its cultural attraction can be attributed to its cultural diversity that reflects its colonial history and Chinese, Malay, Indian and Arab ethnicities. It is also environmentally friendly, and maintains natural and heritage conservation programs. As English is one of its numerous official languages, it is generally easier for tourists to understand when speaking to the local population of the country, for example, when shopping. Transport in Singapore exhaustively covers most, if not all public venues in Singapore, which increases convenience for tourists. This includes the well-known Mass Rapid Transit (MRT) system.The Orchard Road district, which is dominated by multi-storey shopping centres and hotels, can be considered the centre of tourism in Singapore. Other popular tourist attractions include the Singapore Zoo and its Night Safari, which allows people to explore Asian, African and American habitats at night without any visible barriers between guests and the wild animals. The Singapore Zoo has embraced the "open zoo" concept whereby animals are kept in enclosures, separated from visitors by hidden dry or wet moats, instead of caging the animals. Jurong Bird Park is another zoological garden centred around birds, which is dedicated towards exposing the public to as much species and varieties of birds from around the world as possible, including a flock of one thousand flamingos. The tourist island of Sentosa, which attracts more than 5 million visitors a year, is located in the south of Singapore, consists of about 20-30 landmarks, such as Fort Siloso, which was built as a fortress to defend against the Japanese during World War II. Guns from the World War II era can be seen at Fort Siloso, from a mini-sized to a 16 pound (7 kg) gun. Recently, the island has built the Carlsberg Sky Tower, which allows visitors to view the whole of Sentosa, as well as the Sentosa Luge, a small one- or two-person sled on which one sleighs supine and feet-first. Steering is done by shifting the weight or pulling straps attached to the sled"s runners. Singapore will have two integrated resorts with casinos in 2010, one at Marina Bay and the other at Sentosa which the government announced during a parliament session on April 18, 2005.There are various shopping belts in Singapore, Marina Bay, Bugis Street, Chinatown, Geylang Serai, Kampong Gelam Arab Street, Little India, North Bridge Road, Orchard Road, Riverside, Shenton Way Raffles Place and The Suburbs.Singapore seeks to be the business hub of Southeast Asia and has an expansive shopping precinct located in the Orchard Road district. Many multistorey shopping centres are located at Orchard Road; the area also has many hotels, and it"s the main tourism centre of Singapore, other than the Downtown Core. The local populace also use Orchard Road for shopping extensively.Other than Orchard Road, Singapore"s largest shopping centre, VivoCity, has also attracted millions of people since its opening in 2006.[13]To further encourage tourists to shop at Singapore, the Singapore Tourism Board and various organizers organize the Great Singapore Sale yearly. Shoppers can enjoy great discounts and bargains at participating outlets. The Singapore Tourism Board introduced "Late Night Shopping" in 2007.[14] Tourists can catch "Late Night Shopping" on Orchard Road up till 11pm every Saturday and enjoy special deals or promotions by participating retailers.Singapore is a haven for the arts all year round. Its dynamic arts scene is richly influenced by their indigenous Malay culture, the heritage of Chinese and Indian migrants, as well as the city"s international outlook. As new contemporary forms evolve, traditional art forms are simultaneously being preserved to create an arts culture that is uniquely Singapore.The Art Districts in Singapore include Central Arts Districts, Chinatown Arts Belt, Dempsey and Tanglin, Little India, and Riverside. The are also various art museums in Singapore like the Asian Civilisations Museums at Empress Place and Old Tao Nan School, Singapore Art Museum, and NUS Museums.Many of Singapore"s performing arts venues and institutions are more than just performance locations _ they are architectural marvels in their own right. These venues include the Singapore Repertory Theatre, Esplanade - Theatres on the Bay, The Substation and the University Cultural Centre.Sentosa is a relatively large island of Singapore located to its south. Along with a beachfront resort, the island"s tourist attractions include Fort Siloso, its historical museum, the Underwater World aquarium and the Carlsberg Sky Tower. Singapore will also be building two casinos (integrated resorts), one on Marina Bay and one on Sentosa. Singapore has a variety of parks and projects which often feature its natural tropical environment.The Singapore Zoo and Night Safari, allows people to explore Asian, African and South American habitats at night, without any visible barriers between guests and the wild animals.Singapore has its Singapore Botanical Gardens open to the public that is 52 hectares large, and includes the National Orchid collection with over 3000 types of orchids growing.Recently the government has also been promoting the Sungei Buloh Wetlands Reserve as a quiet getaway from the stress of modern life.The Bukit Timah Nature Reserve is an extensive nature reserve which covers much of the Bukit Timah Hill, and is the only remaining place where primary rainforest still exists on the island.The Jurong BirdPark includes extensive specimens of exotic bird life from around the world, including a flock of one thousand flamingos.Pulau Ubin, an island offshore Singapore, is slowly becoming a popular tourist spot. The nature wildlife there is left undisturbed.Singapore is among the top five countries in the world for nightlife, fine dining and shopping.[15] Some popular nightspots in Singapore include:Boat Quay is a historical quay in Singapore which is situated upstream from the mouth of the Singapore River. Shophouses on it have been carefully conserved and now house various bars, pubs and restaurants.Clarke Quay is a historical riverside quay and a buzzing party central in Singapore, and is situated even further upstream from the mouth of the Singapore River than Boat Quay is. Presently, five blocks of restored warehouses house various restaurants and shops such as antique shops. There are also moored Chinese junks (tongkangs) that have been refurbished into floating pubs and restaurants. Crazy Horse Paris opened their third cabaret show worldwide in Clarke Quay in December 2005, but ended operations in February 2007 owing to poor business. The Ministry of Sound opened at Clarke Quay in December 2005 and is one of the most popular nightclubs in the city currently.Clarke Quay also boasts more than 50 eateries offering over 20 different types of cuisine, and more than 20 bars, clubs and pubs. Some of the world"s best pubs are located in Clarke Quay.用英语介绍新加坡写作思路：根据题目要求，介绍新加坡特色景点。Singapore is a small country.新加坡的国土面积很小。Singapore"s climate is very pleasant.
