表示推测的情态动词。 在英语中，表示对某件事物的确 定程度，即表示推测的时候，我们
might, could, may, can’t, couldn’t.
一. can和could的区别和用法 1. can表示体力和脑力方面的能力, 或根 据客观条件能做某种动作的“能力”。 例如： Can yo
u speak English？ Can you make a cake？ can用在否定句和疑问句中时有时表 示说话人的 “猜测”或 “不肯定”。
例如： Can the news be true？ (在日常会话中, can可代替may表 示“允许”, may比较正式) 2. could 是 can的过去式, 表示过去有
She couldn’t skate when she was
five years old. could be true． （能力） （可能性） At that time we thought the story could用来提问, 是有礼貌的请求 Could.... Please? 语气较为婉转。
e. g. Could I speak to Mr. Smith, please? 二. Might和may的区别和用法: 1. may的用法: a. 表示”允许”或”请求”。
e. g. May I come in？
在使用这一用法时需注意: may表 示“允许”的否定形式是must not, 意思是“不应该” “不许可”。e. g. —May I take this book out of the reading-room？ —No, you mustn’t． b. 表示说话人的猜测，认为某一 事情“或许”或“可能”发生。
e. g. He may know the answer． c. may用在感叹句中可表示祝愿、 愿望。 e. g. May you succeed．(祝你成功。) May you have a pleasant journey． (一路平安。)

We had to be there at 10:00. 有时两者都可以用, 意思差别不大。 e. g. We must have to leave now. must在表示说话人对事物的推测时 候要注意它比may肯定得多, 相当于汉 语的“一定”或“准是”。(只有在肯 定句中能这样用。)
This must be your room． 在回答由must引起的问题时, 如 果是否定的答复，不能用mustn’t, 而需要用needn’t或don’t have to, 因为mustn’t是“一定不要”的意
