－Must I finish my composition (作文) right now?
－No, you _______.You can hand it in tomorrow.| A．can’t | B．mustn’t | C．needn’t | D．mayn’t |
|
答案
| C |
解析
试题分析：must是“必须”的意思。当其变为一般疑问句时，否定回答要用needn’t“不必”；肯定回答用must“必须”。mustn’t不是“不必”的意思，而是表示一种禁止，一定不能做的意思。Can’t表示“不能”mayn’表示“不能”。所以本题选C。
点评：本题很容易受前面所学情态动词的影响，如can、will、should等。在平时的学习中应注意它们的回答方式。 |
