被动语态(复习)【语法精点】
Ⅰ. 被动语态
一、基础点拨
1.被动语态的概念。
语态是动词的一种形式,用来表明主语与谓语动词之间的关系。英语动词有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。
2.被动语态的构成。
被动语态由“be+动词的过去分词”构成,动词be有人称、数和时态的变化,其变化规则与be作为系动词的变化完全一样。 各种时态的被动语态的谓语动词形式如下: 1 *A lot of books are kept in our school library.
我们学校图书馆有许多藏书。
2*They were asked to speak at the meeting.
他们被邀请在会议上讲话。
3*The class meeting will be held next Saturday afternoon.
班会将会在下周六下午召开。
4*They said the work would be finished the next day.
他们说这项工作第二天就能完成。
5*A new library is being put up in their school now.
他们学校正在建新图书馆。 6 *The equipment was being examined at this time yesterday.
昨天这个时间正在检查设备。
7*Many stamps have been collected by me since last year.
从去年开始我收集了许多邮票。
8 *She said this airport had never been used.
她说这个机场没有使用过。
9 *The project will have been completed before July.
七月份之前就会完成这项工程。
10 *He told me that his new clothes would have been made very soon.
他告诉我他的新衣服将很快做好。【探究寻规】
用所给动词或短语的适当时态和语态完成句子。
1. Rice ________(grow) in many Asian and some European
countries.
2. Yuan Longping ______________(bring up) in China.
3. The new hybrid rice _________________(develop) by the
Yuan Longping High-tech Agricultural Company of China. is grownwas brought uphas been developed 3. 被动语态的特殊结构形式。
(1) 带情态动词的被动结构。其形式为:情态动词+be+过去分词。
*The question needn’t be discussed.
这个问题不必讨论。
*The classroom must be cleaned at once.
这个教室必须立即打扫。 (2) 有些动词可以有两个宾语,在用于被动结构时,主动结构中的间接宾语变为主语时,直接宾语仍然保留在谓语后面;直接宾语变为主语时,间接宾语前通常加上介词for/to。
*He was asked a number of questions at the press conference.
在记者招待会上人们问了他很多问题。
*A new MP4 was given to him as a birthday present/gift.
他收到了一个新MP4作为生日礼物。 二、难点突破
在下列情况中,谓语形式是主动的,但具有被动的含义。
(1)“系动词look, sound, feel, taste, smell, prove, appear+形容词”构成的系表结构,主动形式表示被动意义。
*The food tastes delicious.
这种食物尝起来很可口。
*The idea sounds good.
这个主意听起来不错。 (3)动词want, need, require, deserve后接动名词的主动形式表示被动意思,这时动名词和句中的主语存在逻辑上的动宾关系。
*The room needs cleaning.
= The room needs to be cleaned.
这间房屋需要打扫。
(4)be worth doing sth. 动名词和句中的主语存在逻辑上的动宾关系。
*The film is well worth seeing.
这部电影很值得一看。【高考体验】
掌握被动语态的答题技巧:
1. 判断主语与谓语之间的逻辑关系。
2. 注意动词是及物的,还是不及物的。
3. 要熟记没有被动语态形式的常见的动词。1. (2013·福建高考)The famous musician, as well as his students, ______to perform at the opening ceremony of the 2012 Taipei Flower Expo.
A. were invited B. was invited
C. have been invited D. has been invited
解题关键: 确定真正的主语为The famous musician,且与invite之间是被动关系。思路分析:选B。考查主谓一致。句意:这位著名的音乐家及其学生受邀在2012年台北花博会开幕式上表演。as well as连接两个并列的名词作主语,谓语动词应和前面的名词一致,故排除A、C两项。本题只是陈述在过去的时间发生的事,故用一般过去时,由于the famous musician和invite之间是被动关系,故选B。
易错误区:学生易误选选项A。as well as, with, along with, together with等连接的两个名词短语作主语,谓语动词应和前面的名词一致,故排除A项。2. (2013·辽宁高考)We are confident that the environment ______ by our further efforts to reduce pollution.
A. had been improved
B. will be improved
C. is improved
D. was improved
解题关键: 根据句意确定应该选用一般将来时,而且environment与improve之间存在逻辑上的被动关系。
思路分析:选B。考查时态和语态。句意:通过在减少污染方面的进一步努力,我们相信环境将会有所改善。根据句意此处应用一般将来时且为被动语态,故选B。3. (2012·四川高考)They are living with their parents for the moment because their own house______.
A. is being rebuilt B. has been rebuilt
C. is rebuilt D. has rebuilt
思路分析:选A。考查动词时态和语态。句意:他们现在和他们的父母住在一起,因为他们自己的房子正在重建。根据句意可知,此处强调现在正在发生的动作,故应用现在进行时,且房子与重建之间为动宾关系,所以应用现在进行时的被动式。4. (2012·安徽高考)After school we went to the reading-room to do some reading, only to be told that it______ .
A. was decorated
B. had decorated
C. had been decorating
D. was being decorated思路分析:选D。考查动词时态和语态。句意:放学后我们去阅览室读书,结果被告知阅览室正在装修。由句子的谓语动词went可知,动作发生在过去,而装修正在进行,故需要使用过去进行时;it指代the reading-room,与动词decorate是动宾关系,故需要使用被动语态,所以应该使用过去进行时的被动语态,故选D项。 Ⅰ. 句型转换

C. has been built D. is being built
【解析】选D。考查时态和语态。句意:这里正在修建一家新的电影院,他们希望下个月竣工。主语cinema与谓语build之间是被动关系;根据finish it next month“下个月竣工”可知电影院正在建造中,故应该选现在进行时的被动语态形式。3. The way the guests ______ in the hotel influenced their evaluation of the service.
A. treated B. were treated
C. would treat D. would be treated
【解析】选B。考查时态和语态。由句意可知treat的动作与influenced的动作具有同时性,故用一般过去时。客人是“被对待”,故用被动语态。4. His sister left home in 1998,and ______ ever since.

A. required to paint B. required painting
C. requires paint D. requires being painted

A. is used B. are used
C. has been used D. have been used
【解析】选C。考查被动语态和主谓一致。means是单复数同形的名词,此处被every修饰,应该按单数对待。根据后句天空依旧是灰白的,用的是一般现在时,所以前句应是“已经用了每一种可能的方法”,故选用现在完成时。8. Professor Williams keeps telling his students that the future ______ to the well-educated.
A. belongs B. is belonged
C. is belonging D. will be belonged
【解析】选A。考查belong的用法及被动语态。句意:威廉姆斯教授一直告诫他的学生们说未来是属于受过良好教育的人。belong to属于,此词组在使用时要注意,不能用进行时态,也不能用被动语态。故排除B、C、D项。9. Miss Johnson is an able writer,whose first novel ______ when she was still at college.
