| A. | Could,couldn't | B. | Can,couldn't | C. | Could,can't | D. | Must,needn't |
分析 --我可以在这抽烟吗,夫人?
---对不起,你不能.看看这个标志.
解答 答案:C can能;could能,语气比较委婉;can't不能;couldn't不能,语气较委婉;must必须;needn't不需要.第一句是问我可以在这抽烟吗,语气应该是委婉客气的,应该用could;第二空结合句意:对不起,你不能.看看这个标志.没有委婉客气的意思,应该用can't不能,故选C.
点评 本题考查的是情态动词的辨析,理解句意并掌握情态动词的用法是解答本题的关键.
