Read the sentences in the box to the class.        2. Get the students to read the sentences and pay attention to the red body parts.3. Encourage the students to read the sentences aloud.Step 2  Grammar情态动词情态动词本身有一定的词义, 表示说话人的情绪、态度或语气, 但它们不能单独作谓语, 只能和行为动词原形一起构成谓语, 表示完整的意思。本模块我们主要复习以下情态动词: 1. can　否定形式can’t或cannot(1) 表示能力, 意为“能, 会”。I can play table tennis. 我会打乒乓球。(2) 表示请求、允许，意为“可以”。Can you pass me that book? 你能把那本书递给我吗？You can use my bike. 你可以用我的自行车。(3) 表示推测或可能性，多用于否定句或疑问句中。Where can he be? 他可能在哪儿呢？[注意] can’t可用来表示否定的推测，意为“不可能”，语气很强烈。Daming can’t be in the classroom. I saw him playing football on the playground just now. 大明不可能在教室里，我刚刚看见他正在操场上踢足球了。2. could(1) can的过去式，意为“能，会”，表示过去的能力。He could draw when he was young. 他小的时候，他就会画画。(2) could用在疑问句中，表示更加委婉的请求。—Could I use your dictionary? 我可以用一下你的词典吗？—Yes, you can. / Sorry, you can’t. I left it at home this morning.好的，可以。/ 对不起，不行，今天早上我把它忘在家里了。3. must(1) 表示“必须”。I must go now. 我现在必须得走了。You must finish it on time. 你必须按时完成。(2) 表示肯定的推测，意为“一定”,  语气很强烈,  用于肯定句中。否定句中则要用can’t。—There’s someone knocking at the door. 有人在敲门。—It must be Jim. 一定是吉姆。(3) mustn’t意为“不要”, 表示禁止或不允许。You mustn’t sit on the stairs. 你不要坐在楼梯上。 (4) 以must开头的一般疑问句,肯定回答用must, 否定回答要用needn’t或don’t have to, 表示“不必”，而不用mustn’t。—Must I return the book now? 我必须现在归还这本书吗？—No, you needn’t. / Yes, you must. 不，不必。/是的，必须现在归还。4. may和might(1) 表示允许①表示请求允许(即请求别人允许自己做某事), 两者都可用, 只是might表示的语气较委婉(但并不表示过去)。May I come round in the morning? 我早上来行吗?I wonder if I might use your phone. 不知可否用一下你的电话。②表示给予允许(即自己允许别人做某事)，只能用may 而不能用might。You may stop now. 你现在可以停下来了。You may leave when you’ve finished. 你做完以后就可以走。[注意]might 表示允许，通常不表示过去，但是在间接引语(即宾语从句)中可以用作 may 的过去式来转述已给予的允许。She said that he might take her dictionary. 她说他可以拿走她的词典。(2) 表示推测两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小(注意此时的might并不表示过去)。在句型使用方面：may通常用于肯定句或否定句，一般不用于疑问句(疑问句中用 can)，而might 则可用于肯定句、否定句或疑问句。He may be at home now, but I’m not sure. 他可能在家里，但是我不确定。Might he know the answer? 他可能知道答案吗？5. should(1) 表示“应该”，常用来表示劝告、建议, 认为“某人应该做某事”或“有义务、责任做某事”。 We should obey traffic rules. 我们应该遵守交通规则。You shouldn’t leave him alone. 你不应该不搭理他。[注意]此时它可以和 ought to, be supposed to 互换使用 。(2) should (ought to)表示推测时，是指有一定根据的推测，意为“可能、应当”。—When can I come for the photos? I need them tomorrow. 我什么时候可以来拿这些照片？我明天需要它们。—They should be ready by 12:00. 十二点的时候就可以准备好了。It’s nearly seven o’clock. Jack should be here at the moment.快七点了。杰克可能快到了。Step 3  Practice 1.
