题目内容
6.--Must we wear school uniforms every day?--No,you .You only need to wear them on Mondays.( )
| A. | mustn't | B. | may not | C. | don't have to | D. | can't |
分析 --我们每天必须穿校服吗?
--不,你不必.你仅仅需要周一穿它们.
解答 答案:C.
根据No和You only need to wear them on Mondays.可知下面为否定回答,must的含义是必须一定,其否定形式mustn't表示禁止的含义.在这里不是禁止的意思.must的否定回答一般可借助于needn'和don't have to来构成.表不必.故选C.
点评 本题考查了情态动词的用法.注意must的用法以及它的肯否定形式.
