24、意义的句子中的运用：（一）用情态动词表达事实的推测:can，could，might，may，must 可以用来表达对事实的推测。根据说话人对事实的把握性大小，must 表示“肯定”，may / might / can / could 表示“可能”， must只用于肯定句中，may / might 的否定式may not / might not 表示“可能不”, 而can / could 可以用于疑问句，表示“可能，可能吗?”，其否定式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：m
25、ust / 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.

Where can Tom have gone ?情态动词表达虚拟语气：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
28、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could / might / have done: 不然早就例句：1.

30、ld have telephoned him.8.

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。例句：I dare say that my uncle will get the money if I die.will 和would表示“意志”或“愿意”，would 则指过去愿意做例句：1. He said that he would help us.2. You may telephone if you will accept this job.would 可以表达“过去习惯做”类似于“used to do
