通过本课的学习，学生能够：①掌握情态动词must, culd, might, can’t表示推测的不同用法。②在真实情景中运用恰当的情态动词进行合理的推测。
Let’s first enjy a vide.
Hw d yu feel after watching the vide?
Lk at the lyrics(歌词). Can yu tell the meaning f “can” in them?
Yu can be the best.Yu can be a her.Yu can mve a muntain.
Culd yu sing a sng fr us?He can sing very well. We must wear schl unifrms every day. Miss Yi might be nervus. Yu shuld relax yurself.
We’ve learned a lt abut mdal verbs. Nw let’s review sme f them.
两人一组，针对表格左侧的三个问题，运用情态动词must, can’t, might和culd 补充更多的推测。
1. must 表示有把握的肯定的推测的时候，只用于肯定句，意为“ 一定；肯定”。The light is n. He must be at hme nw. 灯亮着呢。他肯定在家。注意：mustn’t 表示“禁止”。
2. can和culd 都可表示猜测，此时culd不是can的过去式，culd语气更委婉，意为“可能”。can 用于肯定句表示理论上的可能性，但实际不一定会发生；用于否定句表示有把握的推测，意为“ 不可能，一定不”。Sctland can be very warm in September.九月的苏格兰有时会很暖和。I saw him at the library. He can’t be at hme nw.我刚刚在图书馆看到他了。他这会儿肯定不在家。
3.may和might都可表示猜测，此时might不是may的过去式，might语气更委婉。两者都可用于肯定句或疑问句，表示把握不大的推测。This vlleyball might/may be Tm’s. He likes playing vlleyball.这个排球可能是Tm的。他喜欢打排球。
不同形式的情态动词表示不同的含义
1.“情态动词+ 动词原形”表示对目前事情的推测。e.g. The bk must be Kate’s.这本书肯定是凯特的。2.“情态动词+be + 现在分词”表示对正在发生的事情的推测。e.g. She must be ding her hmewrk at hme nw.现在她一定正在家里做作业。
3.表示对过去或已完成事件的推测用“情态动词+ have dne”。e.g. He must have knwn the bad news.他一定已经知道了这个坏消息。4.“There + 情态动词+be+ 主语+ 现在分词形式”表示“可能/ 或许/ 一定有……在做……”。e.g. It is nisy. There might be sme bys playing sccer. 太吵了，可能是有些男孩在踢足球。
