21、定式cant / couldnt 表示“不可能”。用情态动词可以对现在或过去的事实进行推测。对不同的时间内容推测有不同的结构。（二）对现在的事实进行推测：主要结构：must / may / might +动词原形 be+名词/形容词/介词短语 be + doing例句：1. You must be Jeanne. Im Mathilde Loisel. We used to know each other very well. 2. They must be in bed already at this time of the night.3. The teacher must be joki

22、ng.4. Freda isnt in class. She must be sick.5. There must be something wrong.6. She might be very clever, but she hasnt got much common sense.7. He may be arriving this evening.8.

23、 news be true ?（三）对过去的事实进行推测：情态动词+have done / been+名词/形容词/介词短语1. Mrs. Longmans must have been a pretty girl in her youth.2. He couldnt have seen Anna yesterday. Shes gone abroad.3. I think I must have left my glasses in the library.4. He might have overslept again.5. Where can Tom have gone ?情态动词表达虚

24、拟语气：表达“本来”，“不然早就”。这是情态动词的一种虚拟语气用法。表示说话人所讲的与所发生的事实相反。表达了说话人的埋怨，后悔的语气。其结构是在一些情态动词后面加 have done 结构。根据要表达的意思，有如下结构：should have done / ought to have done：本应该shouldnt have done / oughtnt to have done：本不该could have done：本来可以neednt have done：本来没必要would like to have done：本来很想would rather not have done: 本来不愿意

25、could / might / have done: 不然早就1. You shouldnt have laughed at his mistakes.2. You could have told us earlier.3. I ought to have bought that dictionary last week.4. You ought not to have spent so much time in reading novels.5. We need not have been in a tearing hurry to catch the train.6. They would

26、 like to have seen that film last film.7. If he had given me his number, I could have telephoned him.8. They might have been frozen to death but for the rescue in time.知识难点：某些情态动词的特殊用法：need 和dare 的两种形式的用法need 和dare可以用做实义动词，后面接不定式（to do）结构，在疑问句和否定句中，加助动词do/does/did/或dont/doesnt/didnt。作为情态动词使用时，主要用于疑问

27、句和否定句中。情态动词neednt（没有必要，不必）相当于dont have to1. It is cold, you need to wear some warm clothes.2. Need I stay here with you for a while ? Thank you, you neednt.3. How dare you speak to parents like that ?注意：句型I dare say+从句。 意思是：我肯定 = Im sure或There is no doubt that+从句。I dare say that my uncle will get the money if I die.will和would表示“意志”或“愿意”，would 则指过去愿意做1. He said that he would help us.2. You may telephone if you will accept this job.
