16.---Must I go to Tom's home to help his Chinese today?---No,you _____.You can go there at weekend.( )
| A. | can't | B. | mustn't | C. | may not | D. | needn't |
分析 --今天我必须去Tom的家帮他学中文吗?
--不,你不必.你可以周末去那里.
解答 答案:D.
根据No和You can go there at weekend.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.故选D.
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.
