14、定）,情态动词must, might, could, cant 后接动词原形，可以表示对现在的情况的推测。,It must be Tonys （是的）,belong to Tony.

15、),2. could 是 can的过去式, 表示过去有过的能力和可能性, 还有怀疑和不肯定的意思(在否定和疑问句中)。 e. g. She couldnt skate when she was five years old. （能力） At that time we thought the story could be true （可能性） 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. may和might的区别和用法: 1. may 的用法: 表示“允许”或“请

16、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 mustnt,表示说话人的猜测，认为某一事情 “或许”或“可能”发生。 e. g.

18、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。) e.g. 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mustnt, 而需要用neednt或 dont have to, 因为mustnt是“一定不要”的意思。,各种预测,按照推测的可能性来区别, must的可能性 最大, may次之。could和might不表示过去 时态, 只是表示推测的可能性比较小。 e.g. It
