题目内容
3.-Dad,I'm so tired!Must I do the chores right now?-No,you .You can do it later.( )
| A. | needn't | B. | couldn't | C. | mustn't | D. | shouldn't |
分析 --爸爸,我太累了!我现在必须做家务吗?
--不,你不必.你可以晚些时候做.
解答 答案:A.
needn't不必;couldn't不可能;mustn't不可以;shouldn't不应该.根据No和You can do it later.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,表示不必.故选A.
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.
