A
) 1. —Can I listen to music in class?
—No, you ______.
A.can't
B.isn't
C.have to
D.don't have to

答案

A

解析

本题考查的是对以“Can”开头的一般疑问句的否定回答结构。其否定回答常用“No, 主语+can't.”或根据语境使用其他否定形式,但选项中仅A选项“can't”符合该语法规则。B选项“isn't”用于be动词引导的一般疑问句答语;C选项“have to”表示“必须”,不符合题意;D选项“don't have to”表示“不必”,也不符合题意。因此选择A。

—______ I'm going to use it myself.

A.Sorry, you can't.
B.Sure, you can.
C.No, you couldn't.
D.No problem.

答案

A

解析

题干的意思是:“——我能用一下你的电脑吗?——_____ 我要自己使用。”根据回答可知此处应是拒绝对方的请求。A项“Sorry, you can't.”意为“抱歉,你不能。”B项“Sure, you can.”意为“当然,你可以。”C项“No, you couldn't.”意为“不,你不能。”在英语中,对于“Could I...”的回答,若为否定回答,应用“Sorry, you can't.”而不用“No, you couldn't.”D项“No problem.”意为“没问题。”根据句意和选项比较可知A项最符合。

) 3. —Could you please go to the library with me tomorrow?
—Sorry, I ______. I'll have a piano lesson.

A.mustn't
B.needn't
C.couldn't
D.can't

答案

D

解析

问句"Could you please..."表委婉请求,回答时用can表能力或许可。由"I'll have a piano lesson"可知不能去,用can't表"不能"。mustn't禁止,needn't不必,couldn't用于过去时,均不符。

C
) 4. —Could you please ______ so much noise?
—Sorry, we won't.
A.not to make
B.not made
C.not make
D.don't make

答案

C

解析

本题考查“Could you please (not) do sth?”的固定句型,表示“请求对方做(不做)某事”,句中需使用动词原形,not make 为否定形式,符合句意要求。
