被动语态专项练习及答案详解

一、单项选择被动语态

1.Please don’t stand up in class until you ______.

A.were told to B.are told

C.are told to D.were told

【答案】C

【解析】

【详解】

考查省略句。句意:直到有人叫你站起来,你才可以在课堂上站起来。在一定的上下文中,为了避免重复,动词不定式在句中可以被省略掉,但是要保留动词不定式的符号to。分析句子可知,本句为一般现在时。故C选项正确。

【点睛】

to代替不定式

在一定的上下文中,为了避免重复,动词不定式在句中可以被省略掉,但是要保留动词不定式的符号to。to代替不定式,常同refuse, want, seem, intend, expect, hope, like, be afraid,

prefer, care, oblige, forget, wish, try,tell等动词连用。

注意:如果不定式中含有be, have,或have been,一般要保留be, have或have been。

本句还原为:Please don’t stand up in class until you are told to stand up。省略句为:Please

don’t stand up in class until you are told to 。故C选项正确。

2.—Have you heard about that school bus accident?

—Yes, fortunately all on board including the driver ________.

A.were saved B.was saved

C.have saved D.has been saved

【答案】A

【解析】

考查动词时态和语态。句意为:——你有没有听说那起校车事故?——嗯,幸运的是,车上所有的人包括司机都获救了。由题干中的Have you heard...可知,事故发生在过去,且all为主语,和save逻辑上构成被动关系,故用一般过去时的被动语态,故答案A符合语境。

3. A human case of H7N9 was reported in 2014 when a woman______ to be infected with the

bird flu virus.

A.confirmed B.had been confirmed

C.was confirmed D.have confirmed

【答案】C

【解析】

试题分析:句意:一例人感染H7N9病毒的报告发生在2014年,当时,一名女性被确诊感染了禽流感。Confirm证实,确认,根据was reported in 2014可知,是过去的事情,先行词是2014,定语从句也用一般过去时,排除B、D;woman与confirm是动宾关系,即她是被确诊的,故选C。

考点:考查时态与被动语态

4.(江苏四校第四次考试)The flood has caused a lot of damage to that area and the figures of

the missing________shortly.

A.will be published B.have been published

C.had been published D.are published

【答案】A

【解析】

考查时态。shortly不久,不多时,在句中作时间状语,表示将来,所以空处应该用将来时。句意为:这场洪水给那一地区造成了很大损失,失踪人数很快就会公布。

答案: A

5.The affairs of each country should be by its own people.

A.elected B.settled

C.developed D.contained

【答案】B

【解析】考查动词。句意为:各国事务应由自己国家的人们解决。由句意可知,选settle,意为“解决”。elect选举;develop 发展;contain 包含,控制。故选B。

6.If we had taken such effective measures much earlier, the river so seriously now.

A.is not polluted B.would not be polluted

C.had not been polluted D.would not have been polluted

【答案】B

【解析】

选B 句意:如果我们早采取有力措施,现在河水就不会污染这么严重。主句表示与现在事实相反的虚拟语气,用would加动词原形。

7.With more forests being destroyed, huge quantities of good earth ________ each year.

A.is washing away B.is being washed away

C.are washing away D.are being washed away

【答案】D

【解析】

【详解】

本题考查现在进行时的被动语态和主谓一致。解题步骤:1. 确定谓语单复数:根据quantity的用法,quantities of和a quantity of后面都可加不可数名词与可数名词复数,但它们作主语时,quantities of...后面的谓语动词用复数,而a quantity of...的谓语动词用单数,故排除A、D项。2. 确定第二空:随着森林的被毁,土壤正在被冲走,故应该用现在进行时的被动语态。句意:随着森林的被毁,大量的优质土壤每年都被冲走。综上,故选D项。

【名师点拨】

quantities of和a quantity of后面加可数名词复数,做主语时后面的谓语动词用复数形式;quantities of后面加不可数名词,做主语时后面的谓语动词用复数形式;a quantity of后面加不可数名词,做主语时后面的谓语动词用单数形式。rge quantities of money have

been sent there大量的钱已经被送到那里;A large quantity of money has been wasted.大量的钱已经被浪费;2.A large quantity of books have been offered to us.大量的书已经提供给我们; Quantities of nuts are on the table.大量的坚果在桌子上。

8.—I wonder why Robert hasn’t shown up at the interview yet. It’s a pity if he missed

—I’m not sure, but he _______ in a traffic jam riding here.

A.could stuck B.should stuck

C.must have stuck D.might have been stuck

【答案】D

【解析】

考查含情态动词的被动语态。上句:我想知道为什么罗伯特面试还没有出现。如果他错过了很可惜。下句:我不确定,但是他可能被困于交通堵塞。此处表示对过去已经发生事情的推测应该用情态动词的完成式,根据句意可知是被动,故答案为D。

9.—Have you moved into the new house?

—Not yet. It ________.

A.has been built B.was built

C.is being built D.had been built

【答案】C

【解析】考查动词的时态和语态。句意:——你搬进新家了吗?——仍旧没有,它仍旧正在建设。根据语境可知,It指代上文提到的the new house,是第三人称单数,与built是被动关系,用被动语态,结合句意,built这一动作表示正在进行的动作。故选C。

10.Various efforts ________ in the past decades to protect the environment.

A.had made B.have made

C.were made D.have been made

【答案】D

【解析】考查时态和语态。句意:在过去的几十年里,为保护环境做出了各种努力。根据in the past decades可知句子用现在完成时态,efforts是句子主语,复数形式,和谓语动词make之间是被动关系,所以此处用现在完成时态的被动语态,故答案为D。

11.----Have you telephoned your father?

--- Yes, he back next week.

A.is expected B.expects C.will expect D.will be expected

【答案】A

【解析】

试题分析:句意:--你给你的父亲打电话了吗?—是的,他有望明年回来。这里sb be

expected to do现在现在盼望明年回来,所以用一般现在时的被动语态,这里he应指的是父亲。根据句意故选A。

考点:考查动词时态及语态的用法。

12.Due to the country’s growing rate of urbanization, China’s migrant population _______ to be

over 200 million by 2020.

A.predicts B.is predicted C.will have been predicted D.will be predicted

【答案】B

【解析】考查时态和被动语态。句意:由于中国城市化的速度不断提高,到2020年,中国的流动人口预计将超过2亿。结合句意可知,用一般现在时态的被动语态,句子主语是population,单数第三人称形式,故答案为B。该题容易误选D项,是现在预计,而不是将来预计,故用现在时态。

13.A rescue worker risked his life saving two tourists who ________ in the mountains for two

days.

A.are trapping B.have been trapped

C.were trapping D.had been trapped

【答案】D

【解析】

考查语态和时态。句意:一个救援人员冒着生命危险挽救了两个被困在山里两天的旅游者。“who ___ in the mountains for two days”是定语从句,修饰two tourists,two tourists和trap之间是被动关系,该空应用被动语态。由risked可知,营救人员救游客是过去的事情,被困两天发生在营救人员救了他们之前,即“过去的过去”,该空应用过去完成时态。综上,D选项正确。
