8A Chapter 4 Writing---WorksheetTask One: Read the letter below and fill in the blanks.Dear Gracie,I have just moved to Beijing from Boston for two months, and I really want to tell you how different between the two cities.Although the names of both cities begin with the letter B, Boston and Beijing are very different places. First, Beijing is special because it is the capital of China. Boston is just an ordinary（普通的）city in America. The climate（气候）of Beijing is much dryer than that of Boston. It seldom rains or snows there. Boston sometimes rains heavily, especially in the spring, and has lots of snowstorms（暴风雪）every year. Beijing is a city with several thousand years of history, while Boston is only a few hundred years old, so it is much younger than Beijing. Everywhere you go in Beijing feels very crowded, but there are far fewer people on the streets in Boston. Therefore，the traffic in Beijing is a lot worse and the air is far more polluted than that in Bo ston. It is easier to get sick there. Boston’s air is clean and clear most of the time, which makes it a very healthy place to live. However, people in Beijing are trying their best to make the environment better.I love to live in Beijing, because food here is more delicious and people are more friendly. I also miss Boston, because the air there is much cleaner.Can you tell me something about your city—it is Shenzhen, right? I’m looking forward to seeing you soon.Best regardsSimonFill in the blanks:1.Beijing is the _____________ of China.2.Beijing __________ rains or snows, but Boston sometimes rains _____________. So the _________of Beijing is ________ __________ than _______ in Boston.3.Boston is _____________________ than Beijing, because Beijing is a city with ___________________________________ of history, while Boston is only ________________________________.4.There are ______________ people in Boston than in Beijing. So the traffic is ______________ inBeijing and the air is _________________ than that in Boston.5.Simon loves Beijing, because the food there is __________________. And he also misses Boston,because the air there is _________________.Task Two: Group work: make a dialogue with your partners according to the table on the screen, you might go like this:A: Which city do you prefer, Beijing or Shenzhen?B: I prefer…, because…(ask the next student) Which city do you prefer, Beijing or Shenzhen?C: I prefer…, because…(ask the next student)……Task Three:Write a letter back to David.1.

一. 教学内容：Module 3 Computers and the Internet二. 教学重点、难点：1. 一般将来时will的用法，用will来礼貌地表达某一请求。
2. 熟练灵活而准确地掌握本模块的“重点词汇及句型”3. 能阅读有关将来活动的问答和有关在网上进行信息搜索的英语说明。
三. 语法：写作指导，how to write e-mail.1. 在标题栏（heading）上“收件人（to）”框中输入收件人的e-mail地址。

I’ll find you some nice books. 我将给你找一些好的书。
find you some nice books＝find some nice books for you.<扩展>这种结构在英语语法中称之为双宾语，一般分两大类：第一类：“vt＋sb.＋sth.”＝“vt＋sth.＋to sb.”其中vt为及物动词，sth.为直接宾语，sb.为间接宾语，能这样接双宾语的及物动词有“七给”（give, pass, lend, write, show, send, hand）和一带“bring”等。
如：please give me the book＝please give the book to me第二类“vt＋sb.＋sth.”可转化为“vt＋sth.＋for＋sb.”能这样接双宾语的及物动词有draw （画），make（制作），buy（买），cook（做饭），sing（唱歌）等。
如：My mother bought me a new bike yesterday.＝My mother bought a new bike for me yesterday.注：当直接宾语为代词时，必须用“vt＋sth.＋to/for＋sb.”结构。
如：Please give it to Lucy. 请把它给露西。
Who made it for you?谁给你做的？2. Will everyone be quiet, please?请大家安静，好吗？此句表达更加委婉。
<扩展>注意please的位置，句中、句后，如：Will you please sit down?＝Will you sit down, please?3. I can’t switch this computer on. 我不能打开这个电脑。
switch sth. on或switch on sth. 注意：当sth.是名词时是句中、名后，sth.是代词时必须位于中间，如：switch this computer on＝switch on this computer switch it on<扩展>当动词＋副词构成的短语时，都符合上面的原则，如：put on, turn down/up, take off （脱下），switch on/off打开（关上）开关，click on点击，work out算出来，take out拿出来当动词＋介词构成的短语时，当sth.是名词或代词时，必须放在其后。
如：look after照顾，think about考虑，look for寻找，look at看着……注意：work on从事于，get on/off上（下）车，当sth.是代词时必须放在最后。
4. you’ll be able to see them soon. 不久你将能看见他们。
be able to v. 能，会做某事。
<扩展>can与be able to的区别。
be able to有人称和时态的变化，如：He is able to swim. He will be able to swim. He was able to swim.can是情态动词，它没有人称和时态（过去时除外）的变化。
如：He can swim. He could swim in the past.【典型例题】1. He ______right.A. mayB. maybeC. may be分析：此题考查的是may, maybe, may be的区别：may情态动词表示“可能，可以”后＋v原。
“maybe”副词“也许，大概”可位于句首，也可位于助后动前，may be是两个词“可能是”。
故选择C。
2. May I ask you _______ questions?A. any moreB. some moreC. another more分析：some more, any more“再一些，另外一些”some more用在肯定句，any more用在疑问句，some more用在疑问句中表示希望得到肯定回答。
故选择B。
3. You don’t know how to do an__________A. exerciseB. exercises分析：此题考查的是exercise的用法，exercise作可数名词时，意思为“练习题，操”如：do morning exercises，exercise作不可数名词时，意为“锻炼”do exercise。
故选择A。
【模拟试题】（答题时间：45分钟）一. 单项选择。
