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。,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”。,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”。,May,I take this book out of the reading

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，表示禁止。,-,Must,I hand in my homework now?,-No,you,neednt,.,情态动词表示推测可以分为以下几种情况,:,情态动词,+do,此结构表示对现在或将来情况的推测和判断,Do
