专升本

2022年山东专升本考试备考进行中，试科目为4门公共基础课，为了帮助各位考生更好地梳理学习的知识，临沂专升本考试网小编特为大家整理了本页面。

16. If he ________ to the teacher attentively, he ________ the answer to the problem now.

A. had listened, would have known B. listened, would know

C. listened, would have known D. had listened, would know

【答案】D

【解析】考查混合型虚拟语气。句意：如果他认真听老师讲课了，那么他现在就能够知道这个问题的答案了。根据句意可知，if条件句是对过去的虚拟，谓语动词用had done;而后面主句中的now则提示应该是对现在的虚拟，应该用would +动词原形，所以整个句子是混合型的虚拟语气，正确答案为D。

17.—I believe________ you’ve done your best and ________ things will improve.

—Thank you.

A. that; / B./; / C.what; that D./; that

【答案】D

【解析】考查宾语从句。句意：“我相信你已经尽力并且(我相信)情况会好转”。及物动词后有两个或两个以上的宾语从句时，只有第一个连词that可以省略，故选择D。

18. You ________ all those clothes! We have a washing machine to do that sort of thing.

A.needn’t have washed B.shouldn’t have washed

C.must not have washed D.can not have washed

【答案】A

【解析】考查情态动词。needn’t have done本没有必要做。句意：你本没有必要洗那么多衣服!我们有洗衣机来做那种事情。故选择A。

19. The headmaster showed the foreign friends ________ the school.

A.along B. to C. around D. over

【答案】C

【解析】考查固定搭配。Show ... around,带……参观、巡视;句意：校长带外国朋友参观了学校。

20. Please give the book to ________ wins the first prize.

A.who B.whom C.whoever D.whomever

【答案】C

【解析】考察名词性从句。句意：请把这本书给获得一等奖的人。在题干中，to后面接一个介词宾语从句，空格里做主语。由此排除BD项。A项指具体的谁。C项相当于anyone who引导宾语从句。故C正确。
