高三英语总复习语法系列训练被动语态详解高三英语备课组(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:Theywillbuildanew bridgeovertheriver.(主动)Anewbridgewillbebuiltoverth eriver.(被动)汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:助动词be+及 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,其形式与系动词be的变化 形式完全一样。以give为例,列表如下:一般现在时: am/is/are+given 一般过去时: was/were+given一般将来时: shall/willbe+given 一般过去将来时: should/wouldbe+given现在进行时: am/is /are+being+given过去进行时: was/were+being+given 现在完成时: have/has+been+given过去完成时: had+been+ given将来完成时: shall/will+havebeen+given过去将来完成 时: should/would+havebeen+given?[注]被动语态没有将来进行时和过去将来进行时。( 三)被动语态常用的八种时态1.一般现在时:Peoplegrowriceinthesouthofthec ountry.Riceisgrowninthesouthofthecountry.Thesc hooldoesn''tallowustoenterthechemistrylabwithoutateache r.Wearenotallowedtoenterthechemistrylabwithoutate acher.2.一般过去时:Theyagreedonthebuildingofanewcarfac torylastmonth.Thebuildingofanewcarfactorywasagreed onlastmonth.Thestudentsdidn''tforgethislessonseasily.

(正确)Anewcomputerhavebeenbought.(错误)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。Myunclegavemeap resentonmybirthday.Iwasgivenapresentonmybirthday .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,如上句还可以说:Apresentwa sgiventomeyesterday.保留宾语注意: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。Thecupwithmixturewasshowedtotheclass. Mybikewaslenttoher.一般在下列动词后,间接宾语前用介词for,如:b uild,buy,cook,cut,choose,do,fetch,find,fix,get,keep,ma ke,order,paint,play,sing等。Mothermademeanewskirt.( Anewskirtwasmadeforme.)Themeatwascookedforus. Somecountrymusicwasplayedforus.有些既不用to也不用for, 根据动词与介词的搭配关系。Heaskmeaquestion.(Aquestionwasaskedof me.)PeopleallovertheworldknowtheGreatWall.TheG reatWallisknowntopeopleallovertheworld.(不用by短语)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:不及物动词+ 介词,如:agreeto,askfor,laughat,operatedon,listento,look after,thinkof,talkabout等。Thepatientisbeingoperatedo n.Theproblemissolved.Itneedn''tbetalkedabout.及物动词+ 副词:如:bringabout,carryout,findout,giveup,handin,makeou t,passon,pointout,putaway,putoff,thinkover,turndown, workout,turnout等。Hisrequestwasturneddown.Thespo rtsmeetwillbeputoffbecauseofthebadweather.4.带复合宾语(宾语 +宾补)的动词改为被动语态时,一般把主动结构中的宾语改为主语,而宾语补足语保留在谓语动词后面。如:Wealways keeptheclassroomclean.→Theclassroomisalwayskeptcl ean.Shetoldustofollowherinstructions.→Wewere toldtofollowherinstructions.注意:在see,watch,hear,notice, listento,lookat,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t o,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。Weoftenhearhimpl aytheguitar.→Heisoftenheardtoplaytheguitar.注意:带 有复合宾语的句子,如果宾语补足语是名词,变被动句时,应将宾语变为主语,不要误把宾语补足语的名词作主语。如:Tomato eswerefirsttakenbacktoEuropeandpeoplecalledthemloveap ples.误:Loveappleswerecalledthem.正:Theywerecall edloveapples.5.还有一种短语动词由动词+名词+介词构成,变被动语态有两种形式,如下:1)We takegoodcareofthebooks.Thebooksaretakengoodcare of.Goodcareistakenofthebook.2)Youmustpayatten tiontoyourpronunciation.Attentionmustbepaidtoyour pronunciation.Yourpronunciationmustbepaidattentionto.用于这类结构的短语动词常见的有:catchsightof,makeuseof,payattentionto,setfireto,takecareof,takeholdof,takenoticeof,keepaneyeon等。6.当主动句的主语是nobody,noone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:Nobodycananswerthisquestion.误:Thequestioncanbeansweredbynobody.正:Thequestioncannotbeansweredbyanybody. |
