有关被动语态的几个重要考点

将语态与主谓一致结合起来命题

1. All the employees except the manager ______to work online at home.

A. encourages          B. encourage         C. is encouraged     D. are encouraged

解析:主语是all the employees(复数) ,而不是the manager,排除答案A和C;又因all the employees与encourage是被动关系,要用被动语态,排除B,故选D。

2. A library with five thousand books _______to the nation as a gift.

A. is offered            B. has offered          C. are offered        D. have offered

解析:a library是offer的承受者,要用被动语态,排除B和D;又因主语(library) 是单数,排除C;故选A。注意:with five thousand books是a library是定语。

将语态与虚拟语气结合起来命题

—Don’t you think it necessary that he ______ to Miami but to New York?

— I agree, but the problem is ______ he has refused to.

A. will not be sent; that                          B. not be sent; that

C. should not be sent; what                    D. should not send; what

解析:因he与send是被动关系,排除D;又因it (is) necessary后的that从句的谓语要用“(should+) 动词原形”,排除选项A;答句中的表语从句不缺任何句子成分,用that;故选B。

将语态与倒装结合起来命题

Only after my friend came ______.

A. did the computer repaired                  B. be repaired the computer

C. was the computer repaired                 D. the computer was repaired

解析:因the computer与repair是被动关系,排除A;又因only加状语置于句首,要用部分倒装,排除选项D和B;故选C。

将固定短语中的名词作主语来增加句子理解难度

Good care must ______babies, particularly while they are ill.

A. take                  B. take of               C. be taken             D. be taken of

解析:由固定短语take good care of(好好照看) 是可知,good care与take是被动关系,排除A和B;选项C中又漏掉了of;故选D。

在语境中将语态与时态结合起来命题

1. The number of deaths from heart disease will be reduced greatly if people ______to eat more fruit and vegetables.

A. persuade              B. will persuade      C. be persuaded      D. are persuaded

解析:因people与persuade是被动关系,排除A和B。又因为主语是一般将来时,条件句中用一般现在时,所以选D。

2. Hundreds of jobs ______if the factory closes.

A. lose                     B. will be lost          C. are lost             D. will lost

解析:因lose与jobs是被动关系,排除A和D;又因条件状语从句是一般现在时,主句中的谓语动词应当是一般将来时,故选B。

3. With more forests being destroyed, huge quantities of good earth ______each year.

A. were washed away                            B. is being washed away

C. are washing away                              D. are being washed away

解析:因good earth(沃土) 与wash away(冲走) 是被动关系,排除C;又因quantities of…作主语,谓语动词用复数,排除B;指近阶段(近些年) 正在发生的事,用现在进行时,排除A;故选D。

4. —The window is dirty. —I know. It ______ for weeks.(www.hxen.net)

A. hasn’t cleaned        B. didn’t clean       C. wasn’t cleaned       D. hasn’t been cleaned

解析:由is和for weeks可知,要用现在完成时态,排除B和C;又因It (The window) 与clean是被动关系,要用被动语态,所以选D。

5. —George and Lucy got married last week. Did you go to the wedding?

 —No, I ______. Did they have a big wedding?

A. was not invited                                 B. have not been invited    

C. hadn’t been invited                            D. didn’t invite

解析:因为I与invite是被动关系,又因为邀请应当发生在结婚之前,got married是过去,invite就该是过去的过去,所以用过去完成时的被动语态,只有C正确。

6. The mayor of Beijing says that all construction work for the Beijing Olympics _____ by 2006.

  A. has been completed                         B. has completed

  C. will have been completed                 D. will have completed

解析:因“by+将来时间”通常与将来完成时连用,所以由by 2006可排除A和B;又因为work与complete是被动关系,所以要被动语态,只有C正确。

7. Be careful when you cross this very busy street. If not, you may ______run over by a car.

  A. have                  B. get                  C. become                 D. turn

解析:you与run over是被动关系,选项中只有get才可与过去分词run构成被动语态,故选B。
