Module 3 Change一. 本周教学内容：Unit 4 A more enjoyable school life［教学过程］1. 情态动词could的用法could的否定形式是could not，多缩写为couldn't，两者通常都读作['kudnt]1）表示能力，意思是：能，会例】Could you speak English then？  那时你能讲英语吗？He said he couldn't follow me.  他说他跟不上我注意：①could（能）和was/were  able to 都表示过去一般具有某种能力例】He could (was able to) swim very well when he was nine.  他九岁时就很会游泳②was (were) able to 可以表示过去某时有某种具体的能力并且实际上可以做到，但could表示过去的习惯能力例】Although the driver was badly hurt, he was able to explain what had happened.  司机虽受重伤，但仍能说明发生了什么事2）表示可能性，意思是：可能。

例】That big cinema can seat 2,000 people.  那家大电影院能坐2,000人He said he couldn't come.  他说他不能来3）提出请求、疑问或看法（could是虚拟语气，代替can，在时间上与can没有区别，只是语气比can委婉can语气直爽、肯定）例】----Could you let me have your passport?----Yes, here it is.—看看你的护照好吗？—行，这就是4）表示惊异、不信等情绪（用于疑问和否定句中，此时could与can用法相同，无时间上的差别，用could语气缓和，情绪要弱）例】Who could have taken them？  谁会把它们拿走了呢？She couldn't have left so soon.  她不可能这么快就走了5）表示与事实相反的情况（用于虚拟语气）例】I would certainly do it for you if I could.  要是我能做得到，我一定会为你们做这事儿How I wish I could go with you!  我多么希望和你们一道去！2. 词组would like to现在我们来学一种客气话, 也就是 would like to。

这个词组就是 “要” want to, w-a-n-t t-o, want to 的意思, 不过比较客气下面我们要作一组练习第一个句子用 want to, 第二个句子用的是 would like to，这两句话意思一样M: Nancy wants to see a doctor. F: Nancy would like to see a doctor. M: Henry wants to watch television. F: Henry would like to watch television. 刚才我们学习了怎么用客气话 would like to 作陈述句, 下面我们看一看怎么用这个词组作问句. 比方有一句话: “你要做一个打字员吗?” 英文可以这么说: Would you like to be a typist? 另外一句话: “你要做市政府工作人员吗?” 英文可以这么说: Would you like to be a city worker? M: Would you like to be a fire fighter? F: Yes, I would like to be a fire fighter. M: Would you like to buy this record? F: No, I wouldn't like to buy this record. M: Would you like to have a glass of milk? F: No, I wouldn't like to have a glass of milk. 3. 反身代词1） 列表 I　　　　　you　　　　　you　　　　 she　　　 he myself　　 yourself　 yourselves　 herself　 himselfwe　　　　 they　　　　 it　　　　oneourselves　themselves　 itself　　oneself2）做宾语 a. 有些动词需有反身代词　　absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave　　We enjoyed ourselves very much last night.　我们昨晚玩得很开心。
