题目内容
18.---Is this your eraser?No.It be mine.Mine is in my hand.( )
| A. | may not | B. | mustn't | C. | can't | D. | might not |
分析 --这是你的橡皮吗?
--不,他不可能是我的.我的橡皮在我手里.
解答 答案:C.考查情态动词.句意"--这是你的橡皮吗?--不,他不可能是我的.我的橡皮在我手里.".mustn't一定不可以怎么样(语气比较强烈.).may not也许不(推测时不太有把握).can't 不可能(推测时很有把握).needn't不必.结合Mine is in my hand我的在我手里.可知表示推测时有把握,语气比较肯定.因此用C.其它不符合.
点评 情态动词无人称和数的变化;不能单独使用,必须与其后的动词原形构成谓语.否定形式通常在后面加not.此题要注意区分情态动词的不同用法.
