1、被动语态语法全面讲解一、语态分类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。如：They will build a new bridge over the river. (主动)被动语态表示主语是动作的承受者。如：A new bridge will be built over the river. (被动)在被动句中常能翻译出：“被”、“给”、“由”、“受”等中文意思。二、被动语态的时态、人称和数的变化（1）一般现在时：am / is / are + done The car is driven by my father everyday. （2）一般过去时：wa
2、s / were + done The car was repaired yesterday.（3）一般将来时：shall / will + be done The homework will be done in five minutes. （4）现在进行时：am / is / are + being + done The problem is being discussed by students now. （5）过去进行时：was / were + being + done The bike was being repaired when I got there.（6）现在完成时：hav

Your homework must be handed in after class. 四、 被动语态的使用1.当不知道或没有必要指出动作的执行者时，这时往往不用by短语。 如：“Mr. Li, the cup was broken after class. ”
4、2.突出或强调动作的承受者，如果需要说出动作的执行者，用by短语。 如：The cup was broken by Paul.3.当主语既不是动作的执行者，也不是动作的承受者时，这时常用in +名词作状语，而代替 by短语。These cars were made in China.五、语态转换时所注意的问题1.把主动语态变为被动语态，时态一致，主谓一致。We have bought a new computer.A new computer has been bought.2. 含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语My uncle gave me a present
5、on my birthday. I was given a present on my birthday.如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词 A present was given to me yesterday.注意：1.一般在下列动词后，常在间接宾语前用介词 to，如：bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell等。(1) The book was showed to the class. (2) My bike was lent to he
6、r.3.由动词+介词或副词构成的短语动词，要把它们作为整体看。即把它们看成一个及物动词，介词或副词不可拆开或漏掉。这类动词有：动词+介词，归类：agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about，bring about, carry out, find out, give up, hand in, put away, put off, think over, turn down, work out, turn out等例如：The patient is being opera
7、ted on. The problem is solved. It neednt be talked about.4.当主动句的主语是nobody, no one等含有否定意义的不定代词时，被动句中将其变为anybody。如：Nobody can answer this question.误：The question can be answered by nobody. 正：The question can not be answered by anybody.anything, anybody, anyone等不定代词，在被动句中应将其分别变为nothing, nobody, no one如
8、：They havent done anything to make the river clean.误：Anything hasnt been done to make the river clean.正：Nothing has been done to make the river clean.5.以who为主语开头的疑问句，变被动时，用by whom放在句首。如：Who wrote the story?误：Who was the story written? 正：By whom was the story written?6.有些动词，当它们和well, badly, easily等副词
9、连用时，表示主语内在品质或性能，用主动表示被动。常见的有：write, read, clean, sell, wash, cook等。如：(1) The cloth washes easily.这布很好洗。(2) The new product sells well.这新产品很畅销。对比：The books sell well. (主动句)The books were sold out. (被动句)The meat didnt cook well. (主动句)The meat was cooked for a long time. (被动句)7.下列情况主动句不能改为被动句：感官系动词一般用主
