丹尼尔和阿美来到历史博物馆。丹尼尔被木乃伊的模型吓坏了，拉着阿美要离开。结果怎么样呢？ May: Danny, see, this is the museum of history. We are in the Egypt Hall. Daniel: What"s that in the white cloth? May: It"s a model of Egyptian mummy. Daniel: Egyptian mummy…May , could we leave here? May: Why, Danny? We just came in. Daniel: It looks scaring. May, I am afraid of ghosts. May: They are preserved dead bodies, not ghosts. Daniel: Ghosts, or dead bodies, whatever, I don"t want to see them anymore. Let"s go, May. May: Oh, God. I shouldn"t have let you watch “The Witch”. Daniel: I have been having nightmares these days. May: Danny, listen, there are no ghosts in this world, OK? Daniel: OK. But May, where do people go after they die? May: I don"t know, Danny. 阿美：丹丹，看，这就是历史博物馆。我们在埃及馆。 丹尼尔：那个裹着白布的是什么？ 阿美：那是埃及木乃伊的模型。 丹尼尔：埃及木乃伊……阿美，我们能离开这儿吗？ 阿美：为什么，丹丹？我们刚进来呀。 丹尼尔：它看起来吓人。阿美，我怕鬼。 阿美：它们是经过防腐处理的尸体，不是鬼。 丹尼尔：不管是鬼还是尸体，我再也不想看见它们了。我们走吧，阿美。 阿美：哦，天哪。我真不该让你看《巫婆》。 丹尼尔：我这几天一直做噩梦。 阿美：丹丹，听着，这世界上没有鬼，知道吗？ 丹尼尔：知道了。但是阿美，人们死后去了哪里呢？ 阿美：我不知道，丹丹。经典背诵 RecitationMay: There are various museums in Beijing.

How to save money in univessityHere are 10 ways to Save Money in College/University:1.Live at home if you can. If not, long term leasing of off campus housing is cheaper than staying in dorms/residence.2.Pack your own lunch. Iu2019m a big advocate of brown bagging your lunch as itu2019s a cheaper (and healthier) alternative to eating fast food.3.Take public transit, or if practical, get a bicycle. If class is more than walking distance away from your home, take the bus! Another solution is to get a bicycle. Weather permitting, bicycling to class is not only cost effective, itu2019ll help burn off the beer gut!4.Party on the cheap. Partying is inevitable in college, but you can save a lot of cash if you go to house parties rather than hitting the clubs/bars/pubs downtown.5.Get a degree that offers paid work terms. With some institutions, degrees like Business, Engineering, Nursing, Pharmacy and Social Work offer paid work term opportunities. Not only do work terms offer experience, they usually offer pretty decent money to boot. During my work terms, I saved enough money to pay for books and tuition.6.Get a part time job. I had a part time job throughout University, which is probably one of the biggest reasons why I could pay for food, booze and a girlfriend. :)7.Buy your books used. Even if they upgraded the text book to a new edition the current semester, most of the information will be the same if you purchase an older edition.8.Shop at thrift/second hand clothing stores. If you have the patience to sift through the racks of clothing, there is bound to be diamonds in the rough for a fraction of the cost of buying new.9.Use your campus for recreational activities. If you like working out or playing sports, take advantage of the campus facilities as they are most likely discounted (or free) for students.10.Use your student status for entertainment. Various movie theaters, restaurants and clothing stores typically have programs that offer discounts to students. Take advantage of them.

1、Kafka创建topic命令很简单，一条命令足矣：bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 --partitions 3 --topic test 。2.此命令将创建一个名为test的topic，其中有三个分区，每个分区需要分配三个副本。三。topic创建主要分为两部分：命令行controller逻辑部分。四。后台逻辑将监听zookeeper下对应的目录节点。一旦启动topic创建命令，它将创建一个新的数据节点并触发后台创建逻辑。五个。确定分区副本分配方案（即，将每个分区副本分配给哪个代理）；创建zookeeper节点并将此方案写入/brokers/topics/<topic>节点。五个。确定分区副本分配方案（即每个分区的副本分配给哪个分区）broker上)；创建zookeeper节点，把这个方案写入/brokers/topics/<topic>节点下。6、Kafka controller这一部分的主要任务是：创建分区；创建副本；为每个分区选择leaderISR；；更新各种缓存。

查看Kafka某Topic的Partition详细信息时，使用如下哪个命令（） A.bin/kafka-topics.sh--create B.bin/kafka-topics.sh--delete C.bin/kafka-topics.sh--describe(正确答案) D.bin/kafka-topics.sh--1ist

This is Teachers" Day and a time to be grateful to all teachers. This profession deserves the special recognition and respect. There is no more appropriate time than this to honour you and others in your chosen field. You have my eternal gratefulness. Have a happy Teachers" Day. The whole secret of the teacher"s force lies in the conviction that men are convertible. Teacher, who educate children, deserve more honor than parents, who merely gave them birth; for the latter provided more life, while the former ensure a good life. What sculpture is to a block of marble, education is to the soul. My heart felt thanks to you, dear teacher. On the voyage of life, you have kindled the light of hope for me. What you have done enriches my mind and broadens my view. On this day I honour you sincerely. 作文地带提供参考翻译： 今天是教师节，是我们向所有老师送出祝福的日子。教师这一职业应当受到特别是认识和尊重。没有比今天更适合的时机来表达对您的赞美。我们永远都感激您，节日快乐。 教师的力量在于这样一个信念：人是可以改变的。教师应该得到比家长更多的尊重，因为家长只是给了我们生命，但教师却为我们铸就了生活之路。教育之于灵魂，犹如雕刻之于大理石。我深深地感谢你，老师！在我生命的航程中，您为我点亮了希望的灯盏。您丰富了我的思想，开阔了我的视野。今天我衷心地感谢您。没有人比您更应该得到这样的感谢。Directions: For this part, you are allowed 30 minutes to write a short essay entitled Should the University Campus Be Open to Tourists?

Kafka最核心的思想是使用磁盘，而不是使用内存。经过了解发现磁盘的顺序读写速度和内存持平。而且Linux对于磁盘的读写优化也比较多，包括read-ahead和write-behind，磁盘缓存等。如果在内存做这些操作的时候，一个是JAVA对象的内存开销很大，另一个是随着堆内存数据的增多，JAVA的GC时间会变得很长，使用磁盘操作有以下几个好处：1、磁盘缓存由Linux系统维护，减少了程序员的不少工作。2、磁盘顺序读写速度超过内存随机读写。3、JVM的GC效率低，内存占用大。使用磁盘可以避免这一问题。4、系统冷启动后，磁盘缓存依然可用。

如何决定kafka集群中topic,partition的数量，这是许多kafka用户经常遇到的问题。本文列举阐述几个重要的决定因素，以提供一些参考。 分区多吞吐量更高 一个话题topic的各个分区partiton之间是并行的。在producer和broker方面，写不同的分区是完全并行的。因此一些昂贵的操作比如压缩，可以获得更多的资源，因为有多个进程。在consumer方面，一个分区的数据可以由一个consumer线程在拉去数据。分区多，并行的consumer（同一个消费组）也可以多。因此通常，分区越多吞吐量越高。 基于吞吐量可以获得一个粗略的计算公式。先测量得到在只有一个分区的情况下，Producer的吞吐量(P)和Consumer的吞吐量(C)。那如果总的目标吞吐量是T的话，max(T/P,T/C)就是需要的最小分区数。在单分区的情况下，Producer的吞吐量可以通过一些配置参数，比如bath的大小、副本的数量、压缩格式、ack类型来测得。而Consumer的吞吐量通常取决于应用程序处理每一天消息逻辑。这些都是需要切合实际测量。 随着时间推移数据量的增长可能会需要增加分区。有一点需要注意的是，Producer者发布消息通过key取哈希后映射分发到一个指定的分区，当分区数发生变化后，会带来key和分区映射关系发生变化。可能某些应用程序依赖key和分区映射关系，映射关系变化了，程序就需要做相应的调整。为了避免这种key和分区关系带来的应用程序修改。所以在分区的时候尽量提前考虑，未来一年或两年的对分区数据量的要求。 除了吞吐量，还有一些其他的因素，在定分区的数目时是值得考虑的。在某些情况下，太多的分区也可能会产生负面影响。 分区多需要的打开的文件句柄也多 每个分区都映射到broker上的一个目录，每个log片段都会有两个文件（一个是索引文件，另一个是实际的数据文件）。分区越多所需要的文件句柄也就越多，可以通过配置操作系统的参数增加打开文件句柄数。 分区多增加了不可用风险 kafka支持主备复制，具备更高的可用性和持久性。一个分区（partition）可以有多个副本，这些副本保存在不同的broker上。每个分区的副本中都会有一个作为Leader。当一个broker失败时，Leader在这台broker上的分区都会变得不可用，kafka会自动移除Leader，再其他副本中选一个作为新的Leader。Producer和Consumer都只会与Leader相连。 一般情况下，当一个broker被正常关机时，controller主动地将Leader从正在关机的broker上移除。移动一个Leader只需要几毫秒。然当broker出现异常导致关机时，不可用会与分区数成正比。假设一个boker上有2000个分区，每个分区有2个副本，那这样一个boker大约有1000个Leader，当boker异常宕机，会同时有1000个分区变得不可用。假设恢复一个分区需要5ms，1000个分区就要5s。 分区越多，在broker异常宕机的情况，恢复所需时间会越长，不可用风险会增加。 分区多会增加点到点的延迟 这个延迟需要体现在两个boker间主备数据同步。在默认情况下，两个boker只有一个线程负责数据的复制。 根据经验，每个boker上的分区限制在100*b*r内（b指集群内boker的数量，r指副本数量）。 分区多会增加客户端的内存消耗 kafka0.8.2后有个比较好的特色，新的Producer可以允许用户设置一个缓冲区，缓存一定量的数据。当缓冲区数据到达设定量或者到时间，数据会从缓存区删除发往broker。如果分区很多，每个分区都缓存一定量的数据量在缓冲区，很可能会占用大量的内存，甚至超过系统内存。 Consumer也存在同样的问题，会从每个分区拉一批数据回来，分区越多，所需内存也就越大。 根据经验，应该给每个分区分配至少几十KB的内存。 总结 在通常情况下，增加分区可以提供kafka集群的吞吐量。然而，也应该意识到集群的总分区数或是单台服务器上的分区数过多，会增加不可用及延迟的风险。

[TOC] 本篇接着讲述 Controller 的功能方面的内容，在 Kafka 中，一个 Topic 的新建、扩容或者删除都是由 Controller 来操作的，本篇文章也是主要聚焦在 Topic 的操作处理上（新建、扩容、删除），实际上 Topic 的创建在 Kafka 源码解析之 topic 创建过程（三） 中已经讲述过了，本篇与前面不同的是，本篇主要是从 Controller 角度来讲述，而且是把新建、扩容、删除这三个 Topic 级别的操作放在一起做一个总结。 这里把 Topic 新建与扩容放在一起讲解，主要是因为无论 Topic 是新建还是扩容，在 Kafka 内部其实都是 Partition 的新建，底层的实现机制是一样的，Topic 的新建与扩容的整体流程如下图所示： Topic 新建与扩容触发条件的不同如下所示： 下面开始详细讲述这两种情况。 Topic 扩容 Kafka 提供了 Topic 扩容工具，假设一个 Topic（topic_test）只有一个 partition，这时候我们想把它扩容到两个 Partition，可以通过下面两个命令来实现： 这两种方法的区别是：第二种方法直接指定了要扩容的 Partition 2 的副本需要分配到哪台机器上，这样的话我们可以精确控制到哪些 Topic 放下哪些机器上。 无论是使用哪种方案，上面两条命令产生的结果只有一个，将 Topic 各个 Partition 的副本写入到 ZK 对应的节点上，这样的话 /brokers/topics/topic_test 节点的内容就会发生变化，PartitionModificationsListener 监听器就会被触发 ，该监听器的处理流程如下： 其 doHandleDataChange() 方法的处理流程如下： 下面我们看下 onNewPartitionCreation() 方法，其实现如下： 关于 Partition 的新建，总共分了以下四步： 经过上面几个阶段，一个 Partition 算是真正创建出来，可以正常进行读写工作了，当然上面只是讲述了 Controller 端做的内容，Partition 副本所在节点对 LeaderAndIsr 请求会做更多的工作，这部分会在后面关于 LeaderAndIsr 请求的处理中只能够详细讲述。 Topic 新建 Kafka 也提供了 Topic 创建的工具，假设我们要创建一个名叫 topic_test，Partition 数为2的 Topic，创建的命令如下： 跟前面的类似，方法二是可以精确控制新建 Topic 每个 Partition 副本所在位置，Topic 创建的本质上是在 /brokers/topics 下新建一个节点信息，并将 Topic 的分区详情写入进去，当 /brokers/topics 有了新增的 Topic 节点后，会触发 TopicChangeListener 监听器，其实现如下： 只要 /brokers/topics 下子节点信息有变化（topic 新增或者删除），TopicChangeListener 都会被触发，其 doHandleChildChange() 方法的处理流程如下： 接着看下 onNewTopicCreation() 方法实现 上述方法主要做了两件事： onNewPartitionCreation() 的实现在前面 Topic 扩容部分已经讲述过，这里不再重复，最好参考前面流程图来梳理 Topic 扩容和新建的整个过程。 Kafka Topic 删除这部分的逻辑是一个单独线程去做的，这个线程是在 Controller 启动时初始化和启动的。 TopicDeletionManager 初始化 TopicDeletionManager 启动实现如下所示： TopicDeletionManager 启动时只是初始化了一个 DeleteTopicsThread 线程，并启动该线程。TopicDeletionManager 这个类从名字上去看，它是 Topic 删除的管理器，它是如何实现 Topic 删除管理呢，这里先看下该类的几个重要的成员变量： 前面一小节，简单介绍了 TopicDeletionManager、DeleteTopicsThread 的启动以及它们之间的关系，这里我们看下一个 Topic 被设置删除后，其处理的整理流程，简单做了一个小图，如下所示： 这里先简单讲述上面的流程，当一个 Topic 设置为删除后： 先看下 DeleteTopicsListener 的实现，如下： 其 doHandleChildChange() 的实现逻辑如下： 接下来，看下 Topic 删除线程 DeleteTopicsThread 的实现，如下所示： doWork() 方法处理逻辑如下： 先看下 onTopicDeletion() 方法，这是 Topic 最开始删除时的实现，如下所示： Topic 的删除的真正实现方法还是在 startReplicaDeletion() 方法中，Topic 删除时，会先调用 onPartitionDeletion() 方法删除所有的 Partition，然后在 Partition 删除时，执行 startReplicaDeletion() 方法删除该 Partition 的副本，该方法的实现如下： 该方法的执行逻辑如下： 在将副本状态从 OfflineReplica 转移成 ReplicaDeletionStarted 时，会设置一个回调方法 deleteTopicStopReplicaCallback()，该方法会将删除成功的 Replica 设置为 ReplicaDeletionSuccessful 状态，删除失败的 Replica 设置为 ReplicaDeletionIneligible 状态（需要根据 StopReplica 请求处理的过程，看下哪些情况下 Replica 会删除失败，这个会在后面讲解）。 下面看下这个方法 completeDeleteTopic()，当一个 Topic 的所有 Replica 都删除成功时，即其状态都在 ReplicaDeletionSuccessful 时，会调用这个方法，如下所示： 当一个 Topic 所有副本都删除后，会进行如下处理： 至此，一个 Topic 算是真正删除完成。

Youth Youth is a lively topic, youth is a mature turning. We have been or are embrace the youth, we will lose our youth. Youth is like a gust of wind blowing, leaving only the dusty back. I want to stay young, however, time is merciless. I do think about the chastity words to record the regretless youth. Some people say that youth is a scrap of paper, of no use. Every attempt nothing and accomplish nothing, only know to eat, drink, play, music, do not know how to study hard, do not know how parents bitterness, do not understand the meaning of life. Also some people, although they are unknown to the public, but they cherish their youth, cherish their own every second. They are studying hard, hard work. Youth is a song, sing the life the most memorable fragment; youth is a painting, draw the outline of the most wonderful scene; youth is a poem, to praise the most beautiful moment in life; youth is the only way which must be passed to each of us in our life, it plays a significant role. As a new era of college students, should cherish the youth, to seize every minute to learn. We must hold to our youth, do not waste one"s life. On the road of growing up, do every thing, each reading a good book, learn every bit of knowledge. We should not idle about all day, abandoned their studies. We want to make sure that the goal of life for themselves, to pursue the ideal of life. This is the youth: full power, full of expectations, voluntary, full of knowledge and the struggle of ambition. Youth, revealed a deep a quality suggestive of poetry or painting; youth, emitting a faint fragrance lovingly. The pace of youth will not stop because of difficulty, the melody of youth is not obstructed by wind and rain and. Youth is the sun, is a sign of confidence; let us raise the youth sailing, let youth where flying, let youth in here! 青春 青春是一个活泼的话题， 青春是一个成熟的转折。 我们曾经或者正在拥抱青春，我们也将失去我们的青春。 青春像一阵风吹过，后面只留下尘土飞扬。我想留住青春 ，然而岁月是无情的。我竭尽思索着想用最朴实无华的字眼来记录这段无悔的青春。 有的人把青春当作是废弃的纸，一无所用。天天无所作为，只知道吃、喝、玩、乐，不懂得好好学习，不懂得父母的辛酸，不懂得人生的意义。 　　 也有些人，他们虽然默默无闻，但是他们却珍惜着自己的青春，珍惜自己所拥有的每一分每一秒。他们正在努力地学习，努力地工作。 青春是一首歌，唱出人生最值得回忆的片段；青春是一幅画，勾勒出人生最精彩的一幕；青春是一首小诗，赞美人生最美 的一刻；青春是我们每个人的必经之路，它对我们的人生起着重大的作用。　 作为一名新时代的大学生，应该要好好珍惜青春，要抓住每一分每一秒来学习。我们要紧握青春，不虚度年华。在成长的道路上，做好每一件事，读好每一本书，学好每一点知识。我们不应该整天游手好闲，荒废学业。我们要为自己确定人生的目标，努力地去追求人生的理想。这就是青春：充满着力量，充满了期待、志愿，充满着求知和斗争的志向。　 青春，流露着浓浓的诗情画意；青春，散发出淡淡的幽香含情。青春的步伐不会因困难而停止，青春的旋律不会因风雨而阻挠。青春是阳光，是自信的标志；让我们扬起青春的风帆，让青春在这里飞扬，让青春在这里启航吧！

三级差不多其实个人觉得都可以与四级差不多了

自己买本教材讲解

　　一、 教材分析与教材处理 　　本节课是七年级英语（仁爱版）下册Unit 6, Topic 1, Section B也就是第六单元第一个话题的第二部分。本话题Is there a clock in your study?介绍了房屋内各个房间的类型、位置，家用物品的名称、摆放位置等。本话题通过在A, B, C, D四个Section中贯穿“There be …”句型，方位介词in, on, behind, under, near, next to, in front of 等语言项目使学生能正确描述某处有某物。 　　上节课Section A学生通过学习对话已经初步接触了“There be…”句型以及位置介词。本节课Section B在此基础上，仍然通过对话形式进一步学习“There be…”句型及方位介词，同时也学会了有关家居及生活用品的新词。在所创设的语言环境中为下一节课Section C的学习，也就是为短文阅读打下基础。 　　二、教学方法与教学手段 　　1、教学目标 　　①、词汇：lamp clock wall table key put away door window model under river 　　②、重点句型：What"s +介词短语？ There be 各种句式 How many +名词复数? 　　How much +不可数名词? 　　③、语法：There be 句型 　　④、话题：a、谈论某处有某物 b、谈论房间、家具及生活用品 　　⑤、语言技能 　　听——能听懂对位置和存在的介绍。说——谈论自己家的房屋和室内摆设。 　　2、目标依据 　　①、依据《新课程标准》的目的和任务。②、依据本话题的要求③、依据学生的具体情况。 　　3、重点与难点 　　①、重点：谈论家具摆设及位置关系，学习“There be… ”句型以及应用句型。 　　②、难点：“There be…” 句型在实践中的应用。 　　重点主要依据《新课程标准》中七年级英语的要求以及本话题要完成的任务而定的。难点主要依据学生的接受能力与中英文差异。 　　4、教材处理 　　在上节课Section A中学生已经学习了有关房间类型的名称以及位置，同时也初步学习了“There be… ”句型以及方位介词。本节课通过复习Jane"s house 导入新课，进一步学习“There be… ”句型，然后在Part3中，通过看图，学生自己问答，巩固了重点句型。Part2与Part4检查了学生的把握情况。这是个循序渐进的`过程，并且布满了生活气息，使学生能自然地开口说，顺利地把握了语言技能。 　　三、学习程序 　　教学手段： 1、直观教学 2、提问式 3、情景教学 4、小组活动 　　第一部分：温故知新 　　设计两道题来巩固Section A内容 　　第二部分：新课导学 　　一、课前自主学习：(见预习导学书） 　　A.自主预习P.27--28相关内容的单词，运用音形结合法，大声朗读单词，识记单词拼写，并掌握其中文意思。 　　B.从课文P27-28中找出重点词组，认真识记并将其用红笔标注在课本上。 　　二、课堂合作探究。 　　Task1:充分运用多媒体图片复习所学方位介词并引入under，near , 让学生总结方位介词。通过图片引入What"s …？句型。 　　Task2:小组合作操练1a对话；完成对话探究。 　　三、课堂展示交流。 　　Task3:通过两人对话操练，完成课文第3、4部分，学习并灵活运用there be句型的陈述句，一般疑问句、特殊疑问句及其答语。 　　四、课堂点拨提升。 　　Task4: 深度探究：1. 如何确定 There be 句型中be的形式？2.

(名词作宾补)Computers have made the work place safer and better. (形容词作宾补)I agreed her to send her to school. (不定式作宾补)They keep their hearts beating well. (现在分词作宾补)I found every student in good health. (介词短语作宾补)2) 注意以下特殊结构：①find it +形容词+to do sth. 此处it作形式宾语，真正的宾语是后面的不定式，形容词作宾补。Some students found it easy to study English well. ②keep sb. /sth. + 形容词We should keep our classroom clean. ③make sb. /sth. + 宾补（形容词、名词、省略to的不定式）We had better make our city move and more beautiful. She made him a superstar. 她让他成了巨星。The boy made the baby smile at last.

个人认为，今年最好的话题莫过于灾难。以最近的动车惨案为引子，可以引入正题，再回想之前几年的各种天灾人祸，可以分类型向人们叙述不同的灾难。part1可以是写最近的一次灾难，引入话题part2写一写迄今为止对人们造成影响的不同灾难（此部分可以写成两个层次，根据你要求分点的不同，方向基本为自然灾害和人为灾害）part3写人们对灾难的看法以及灾难对人们的影响part4出彩的部分，要以鼓励的语气写出人们对打败灾难的坚定信心。基本而言5分钟只能说一个表面问题，如果你们是一个team，可以相互之间进行配合，那样的效果会更好一些。如果需要文章可以hi我，做ppt也可以找我:-)

Aritificial Intelligence (AI) Artificial Intelligence (AI) is the intelligence of machines and the branch of computer science which aims to create it. Major AI textbooks define the field as "the study and design of intelligent agents,"where an intelligent agent is a system that perceives its environment and takes actions which maximize its chances of success. John McCarthy, who coined the term in 1956, defines it as "the science and engineering of making intelligent machines."The field was founded on the claim that a central property of human beings, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine. This raises philosophical issues about the nature of the mind and limits of scientific hubris, issues which have been addressed by myth, fiction and philosophy since antiquity. Artificial intelligence has been the subject of breathtaking optimism, has suffered stunning setbacks and, today, has become an essential part of the technology industry, providing the heavy lifting for many of the most difficult problems in computer science.AI research is highly technical and specialized, so much so that some critics decry the "fragmentation" of the field. Subfields of AI are organized around particular problems, the application of particular tools and around longstanding theoretical differences of opinion. The central problems of AI include such traits as reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects. General intelligence (or "strong AI") is still a long-term goal of (some) research.

topic 是主题，你要写的话题title是作文的题目

楼主这么精明，不会浪费的。加油。

subject多来形容主语，如果特定在教育领域就是科目。topic是话题，常用比较有概括性的词组来表达。
