1、WORD1/9初中被动语态语法讲解(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，被动语态表示主语是动作的承受者。如：They will build a new bridge over the river.()A new bridge will be built over the river.()英语用：助动词 be+与物动词的过去分词构成。(二)被动语态的时态、人称和数的变化主要体现在 be 的变化上，动词的过去分词不变。列表如下：一般现在时：+done一般过去时：+done一般将来时：+done过去将来时：+done现在进行时：am/is/ar

2、e+being+done过去进行时：was/were+being+done现在完成时：+done过去完成时：had+been+done将来完成时：shall/will+have been+done过去将来完成时：should/would+have been+done注被动语态没有将来进行时和过去将来进行时。WORD2/9(三)常见的八种时态中的被动语态1.一般现在时：(1)People grow rice in the south of the country.Ricein the south of the country.(2)The school doesnt allow us to en

5、mputer.A great many lettershim.(五)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，常用被动语态，这时往往不用 by 短语。“Mr.White,the cup（break）after class.”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。These records were made by John Denver.The cup was broken by Paul.3.当汉语句子的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 mad

6、e in China.be made of、be made from(六)主动语态变被动语态的方法（1）My aunt invitedmeto her dinner party.主语谓语宾语Ito her dinner party.主语谓语宾语WORD4/9（2）The school set up a special class to help poor readers.in the school.1.把主动语态的宾语变成被动语态的主语。2.把主动语态的谓语变成被动语态的 be+过去分词，时态要与原句保持一致。3.把主动语态的主语变为介词 by 的宾语，放在被动语态里谓语动词之后，by 短语可

7、以省略。如果原句主语是地点名词，在被动语态中用 in+地点名词作状语。(七)语态转换时所注意的问题1.把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。We have bought a new computer.A new computer.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，另一个不动，一般变间接宾语为主语时比较多.V+sb sth=sb be V-ed sthMy uncle gave me a present on my birthday.Ion my birthday.如果把直接宾语(指物)改为主语，则在间接

8、宾语(指人)前加适当的介词，如上句还可以说：A presentme on my birthday.注意：1.一般在下列动词后，常在间接宾语前用介词 to，如：WORD5/9bring,give,hand,lend,offer,pass,pay,promise,sell,show,take,teach,tell 等。(1)The bookthe class.(show)(2)My bikeher.(lend)2.一般在下列动词后，间接宾语前用介词 for,如：build,buy,cook,cut,choose,do,fetch,find,fix,get,keep,make,order,paint

11、语保留在谓语动词后面。如：(1)We always keep the classroom clean.The classroom.(2)She told us to follow her instructions.We.注意：在 see,watch,hear,notice,listen to,look at,make,feel 等动词后作宾语补足语的动词不定式都不带 to，但改成被动语态后都带 to，这时不定式为主语补足语，也就是说不定式作主语补足语不存在省略 to 的问题。We often hear him play the guitar.Heplay the guitar.5.当主动句的主

12、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,作 by 的宾语，并将谓语动词变为否定的被动语态。如：Nobody can answer this question.The question can be answered by nobody.()The question.6.当否定句中的宾语是 anything,anybody,anyone 等不定代词时，在被动句中应将其分别变为 nothing,nobody,no one 作主语，并将谓语动词变为肯定的被动语态。如：They havent done anything to make the r

13、iver clean.Anything hasnt been done to make the river clean.（）WORD7/9.7.以 who 为主语开头的疑问句，变被动时，用 by whom 放在句首：Who wrote the story?Who was the story written?（）?8.有些动词既是与物又是不与物，当它们和 well,badly,easily等副词连用时，表示主语在品质或性能，是不与物动词，用主动表示被动，这时不用被动语态，常见的有：write,read,clean,sell,wash,cook 等。如：(1)The cloth washes ea
