典型例题
1）---Could I borrow your dictionary?
---Yes,of course,you____.
A.might B.will C.can D.should
答案C.could表示委婉的语气,并不为时态.答语中of course,表示肯定的语气,允许某人做某事时,用can和 may来表达,不能用could或might.复习：will 与you连用,用来提出要求或下命令.should与you 连用,用来提出劝告.
2）---Shall I tell John about it?
---No,you ___.I've told him already.
A.needn't B.wouldn't C.mustn't D.shouldn't
答案A.needn't 不必,不用.wouldn't 将不,mustn't 禁止、不能.shouldn't 不应该.本题为不需要,不必的意思,应用needn't.
3）---Don't forget to come to my birthday party tomorrow.
---______.
A.I don't B.I won't C.I can't D.I haven't
答案B.will既可当作情态动词,表请求、建议、也可作为实义动词表"意愿、意志、决心",本题表示决心,选B.
