中考语法-被动语态一、语态概述 英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。如：Many people speak English. 谓语：speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。所谓“被动语态”，相当于中文中常说的“被”、“由”的句式，如：“他的自行车被偷了。”，“这座楼房是由他们建造的。”再如：English is spoken by many people. 主语English是动词speak的承受者。判断：看下面的两个例句，你来判断哪个是主动哪个是被动？ He opened the door.他开了门。 （_） The door was opened.门被开了。 （_）He speaks English. English is spoken by him.说明：好了，现在我们对被动语态的句子形式有了一个形象的认识，但英语句子是千变万化的，这时就需要你有“火眼金睛”了。下面我们来具体了解一下被动语态的构成。 Exercises:Change the following sentences into the passive voice sentences.1. Some people destroy the environment.2. He doesnt water the flowers every day.3. Does a large population cause many problems?4.They clean their classroom every day.二、被动语态的构成: be + done被动特点强调宾（语）, 构成为be+及物动词的过去分词。行为对象作主语，逻辑主语by来引。1. Disneyland is_（enjoy） by millions of people from all over the world.2. The blouse is _（make）of silk.3.The Great Wall is _（visit）by many visitors every year.4. Many problems are _ (cause)by the large population.谁做的动作不知道，说出谁做的也没必要。动作承受者需强调，用被动语态莫忘了。1. Some stamps were _（steal）last week.2. The PRC was _（found）on October 1, 1949.3. Football is _（play）in most middle schools.4. English is widely _（use）throughout the world now.5. English _（speak）as the main language in America.6. The cake is divided into pieces被动语态由“助动词be及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。am（is,are）现在时，am（is,are）+donewas和were表过去, was（were）+done 完成have（has）been, have（has）been+done 将来，情态，be原形, will（can,may,must）be+done 进行时态两个be， am（is,are）+being+done 说明：别看英语中一会儿主动被动一会儿现在时一会儿过去时啥的，好像看得咱们眼花缭乱啦。其实呢，这么一堆东西归纳起来，就两点：时态和语态。歌诀：被动语态be字变，过去分词跟后面。说明：那么，什么时候用被动语态呢？简单的说，凡是汉语中带“被”的句子，都能转换成英语的被动语态。 几种常用时态的被动语态1.一般现在时： am/is/are+过去分词 肯定句：Bikes are _（sell）in that shop. 否定句：Bikes are not sold in that shop. 疑问句：Are bikes sold in that shop? Yes, they are. / No, they arent.2.一般过去时： was/were+过去分词 肯定句：China was _（liberate）in 1949. 否定句：China was not liberated in 1949. 疑问句：Was China liberated in 1949? Yes, it was. / No, it wasnt.3.一般将来时： shall/will/be going to + be+过去分词 肯定句：An English class will be _（give）by Jack tomorrow. 否定句：An English class will not be given by Jack tomorrow. 疑问句：Will an English class be given by Jack tomorrow? Yes, it will. / No. it wont.4.现在进行时：am/is/are + being+过去分词 肯定句：A car is being _（drive）now. 否定句：A car is not being driven now. 疑问句：Is a car being driven now? Yes, it is. / No, it isnt.5.现在完成时：have / has+ been+过去分词 肯定句：A road has been _（build）by the government. 否定句：A road hasnt been built by the government. 疑问句：Has a road been built by the government? Yes, it has. / No, it hasnt.6.情态动词：情态动词+be + P.P 1）This clock can be _（repair）here. 2）The trees may be _（plant）at other times of the year. 3）The composition must be _（hand）in after class. 4）The young trees should be _（plant）in spring. 三、被动语态的用法（1）不知道或没有必要说明动作的执行者是谁。例如： Some new computers were _（steal）last night. 一些新电脑在昨晚被盗了。（不知道电脑是谁偷的） A Journey to West _ (show) on CCTV every summer.（2）强调动作的承受者，而不强调动作的执行者。例如： The window was _（break）by Mike. 窗户是迈克打破的。 This book was _（write）by him. 这本书是他写的。 歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。 主动态和被动态指的是动词形式，是词法概念；而主动句和被动句则指的是句子结构，从而是句法概念。所谓主动句就是由主动态动词（词组）作谓语动词的句子，而被动句则是由被动态动词（词组）作谓语动词的句子。 四、主动语态变被动语态的方法 （1）把主动语态的宾语变为被动语态的主语。 （2）把谓语变成被动结构（be过去分词）（根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式）。 （3）把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如： All the people _（laugh）at him. He was _（laugh）at by all people. They _（make）the bikes in the factory. The bikes are _（make）by them in the factory. 歌诀：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。 五、含有情态动词的被动语态 含有情态动词的主动句变成被动句时，由“情态动词be过去分词”构成，原来带to的情态动词变成被动语态后“to”仍要保留。歌诀： 情态动词变被动，情态加be加“过分”，原来带to要保留。例如： We can _（repair）this watch in two days. This watch can be _（repair）in two days. You ought to _（take）it away. It ought to be _（take）away. They should _（do）it at once. It should be _（do）at once. 六、含双宾语的主动结构变被动结构口诀：如遇双宾语，最好变间宾。如若变直宾，be done后加to(或for) 含有双宾语的主动句改为被动句时，应将其中一个宾语改为被动结构的主语，另一个宾语仍保留在原处。一种情况是把间接宾语（指人）变为主语，直接宾语（指物）不变；另一种情况是把直接宾语（指物）变为主语，间接宾语（指人）不变，这时，间接宾语前通常加介词to，有时加for。例如：1. My father gave me a new book on my birthday. I was given a new book（by my father）on my birthday.（间接宾语作了主语） A new book was given to me（by my father）on my birthday.（直接宾语作了主语）2. Father bought me a new coat. I was bought a new coat . （间接宾语作了主语） A new coat was bought for me. （直接宾语作了主语）七、补充 一些宾补动词如make, see, hear等在主动语态中可以接动词原形（实为省略to的动词不定式）作为宾语补足语的动词在变被动语态是一定要注意恢复to。如： He made me stand outside. I was made to stand outside（by him）. I saw him play football. He was seen to play football（by him）.有一个顺口溜方便记忆：宾补动词真奇怪，to在句中像妖怪。主动句中to走开，被动句中to回来。主动被动互变1. People speak English in many countries. _2.
