题目内容
5.--- I hand in the report today?---No,you needn't.( )
| A. | Can | B. | Must | C. | Shall | D. | Could |
分析 ---我必须今天交报告吗?
----不,没有必要.
解答 答案:B.结合下文No,you needn't和上下文语境可知上文是说我必须上交吗?故用must开头的一般疑问句,故答案是B.
点评 由must引出的一般疑问句,肯定回答用must,否定回答用needn't,don't need to或don't have to均可,但不用mustn't,因为mustn't表示"不许、禁止"的意思,与问句的原意不符.如:
-Must I stay at home?我必须留在家里吗?
-Yes,you must.是的,你必须留在家里.
(No,you needn't.或No,you don't have to.)(不,不用了.)
