初中被动语态讲解及练习 7页

精品文档，仅供学习与交流，如有侵权请联系网站删除被动语态一、概念：语态是动词的一种形式，它表示主语和谓语的关系。语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。二、主动句变为被动句的步骤：1.把原主动句中的宾语变为被动句的主语　　2.把动词变为被动形式即be+过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。　　3.原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。4.其它的成分（定语、状语）不变。三、被动语态的用法：　　1.一般现在时的被动语态构成：is/am/are+及物动词的过去分词Wecleanourclassroomeveryday.Mymotherasksmetostudyhard.2.一般过去时的被动语态构成：was/were+及物动词的过去分词　　Anewshopwasbuiltlastyear.3.现在完成时的被动语态构成：has/have+been+及物动词的过去分词　　Thisbookhasbeentranslatedintomanylanguages.　　Manyman-madesatelliteshavebeensentupintospacebymanycountries.4.一般将来时的被动语态构成：will+be+及物动词的过去分词　　Anewhospitalwillbebuiltinourcity.　　Manymoretreeswillbeplantednextyear.5.含有情态动词的被动语态构成：情态动词+be+及物动词的过去分词Youngtreesmustbewateredoften.　　Yourmistakesshouldbecorrectedrightnow.Thedoormaybelockedinside.　　Yourhomeworkcanbehandedintomorrow.【精品文档】第7页\n精品文档，仅供学习与交流，如有侵权请联系网站删除6.现在进行时的被动语态构成：am/is/are+being+及物动词的过去分词7.不定式的被动语态：to+be+及物动词的过去分词Therearetwobookstoberead.Therearetwentymoretreestobeplanted.3.感官动词或使役动词使用省略to的动词不定式，主动语态中不带to，但变为被动语态时，须加上to。例：makesomebodydosomething→somebody+be+madetodosomethingseesomebodydosomething→somebody+be+seentodosomethingAgirlsawmywalletdropwhenshepassedby.→Mywalletwasseentodropbyagirlwhenshepassedby.Thebossmadethelittleboydoheavywork.→Thelittleboywasmadetodoheavyworkbytheboss.4.如果是接双宾语的动词改为被动语态时，可以使用直接宾语也可以使用间接宾语作被动语态句子的主语。使用直接宾语(物)作主语时，要在动词后加上介词，这个介词是由与其搭配的动词决定。Hegavemeabook.→Abookwasgiventomebyhim.Heshowedmeaticket.→Aticketwasshowntomebyhim.Myfatherboughtmeanewbike.→Anewbikewasboughtformebymyfather.5.一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。　　Wecan’tlaughathim.→Hecan’tbelaughedatbyus.　　Helistenstotheradioeveryday.→Theradioislistenedtobyhimeveryday.Thenurseistakingcareofthesickman.→Thesickmanisbeingtakencareofbythenurse.不用被动语态的情况　　1)不及物动词或动词短语无被动语态（即多数的瞬间动词）：　　appear,die(死亡),disappear（消失）,end(vi.结束),fail,happen,last,lie,remain,sit,spread,stand【精品文档】第7页\n精品文档，仅供学习与交流，如有侵权请联系网站删除　　breakout,cometrue,fallasleep,keepsilence,loseheart,takeplace.　　如：Afterthefire,verylittleremainedofmyhouse.比较：rise,fall,happen是不及物动词；raise,seat是及物动词。(错)Thepricehasbeenrisen.　　(对)Thepricehasrisen.(错)Theaccidentwashappenedlastweek.　　　(对)Theaccidenthappenedlastweek.(错)Thepricehasraised.　　　(对)Thepricehasbeenraised.(错)Pleaseseat.　　　(对)Pleasebeseated.要想正确地使用被动语态，就须注意哪些动词是及物的，哪些是不及物的。特别是一词多义的动词往往有两种用法。解决这一问题唯有在学习过程中多留意积累。2)不能用于被动语态的及物动词或动词短语：fit,have,hold,marry,own,wish,cost,notice,watch，agreewith,arriveat/in,shakehandswith,succeedin,sufferfrom,happento,takepartin,walkinto,belongto　　如：Thiskeyjustfitsthelock.被动语态练习一、选择题  ()1._____ a new library _____ in our school last year?  A. Is; built   B. Was;  bulit  C. Does;  build  D. Did; build  ( )2. An accident ____ on this road last week.  A. has been happened  B. was happened  C. is happened  D. happened  ( )3.Cotton ____ in the southeast of China.  A. is grown  B. are grown  C. grows  D. grow  ( )4.So far, the moon ____ by man already.  A. is visited  B. will be visited  C. has been visited  D. was visited  【精品文档】第7页\n精品文档，仅供学习与交流，如有侵权请联系网站删除( )5.A talk on Chinese history _____ in the school hall next week.  A. is given  B. has been given  C. will be given  D. gives  ( )6.How many trees ____ this year?  A. are planted  B. will plant  C. have been planted  D. planted   ( )7. A lot of things ____ by people to save the little girl now.  A. are doing  B. are being done  C. has been done  D. will be done  ( )8.Neither of them ______ in China.  A. is made  B. are made  C. were made  D. made  ( )9.Look! A nice picture ____ for our teacher.  A. is drawing  B. is being drawn  C. has been drawn  D .draws  ( )10. Your shoes ____. You need a new pair.  A. wear out  B. worn out  C. are worn out  D. is worn( )11.The doctor _____ for yet.  A. isn't sent  B. hasn't been sent  C. won't be sent  D. wasn't sent  ( )12.--When ___ this kind of computers______? --Last year.  A. did; use  B. was; used  C. is; used  D. are; used   ( )13. The Great Wall ____ all over the world.  A. knows  B.knew  C . is known D. was  known  ( )14.I ____ in summer.  A. born  B. was born  C. have been born  D. am born  ( )15.He says that Mr Zhang _____ to the factory next week. A. is sent  B. would send  C. was sent  D. will be sent( )16.Who _____ this book _____?  A. did; written  B. was; written by  C. did; written  D. was; written  ( )17.Mary ____ show me her new dictionary.  A. has asked to  B.was asked to C.is asked D.asks to  ( )18.A story _____ by Granny yesterday.  【精品文档】第7页\n精品文档，仅供学习与交流，如有侵权请联系网站删除A.was told us B.was told to us C.is told us D.told us  ( )19.The monkey was seen _____ off the tree.  A.jump B.jumps C.jumped D.to jump  ( )20.The school bag ___ behind the chair.  A.puts B.can be put C.can be putted D.can put( )21.Older people ____ well.   A.looks after B.must be looked after C.must look after D.looked after  ( )22.Our teacher ______ carefully.  A.should be listened to   B.should be listen    C.be listened    D.is listened二、将下列句子变为被动语态，每空一词。  1. We can finish the work in t
