Question

【题目】What do you think of the proposal that improvement ____ in the type of vacuum cleaner?

A. be made B. will be made C. would be made D. has to be made

Answer 1

【答案】A

【解析】

考查名词性从句中的虚拟语气。句意：你认为改进这种吸尘器的建议怎么样?名词proposal（建议）后面是that引导的同位语从句，从句应该用虚拟语气（should）+动词原形，且从句主语improvement和make之间是是被动关系，故答案为A。
