第08讲 被动语态       【学习目标】1、要求学生掌握各种时态的被动语态。2、掌握一些词主动表被动。3、掌握主动语态变被动语态的方法。         【基础知识】一．被动语态的时态：1.一般现在时的被动语态：   am /is/ are +动词的过去分词People grow rice in the south of the country.Rice is grown in the south of the country.2.一般过去时的被动语态：  was /were +动词的过去分词The students didn't forget his lessons easily.His lessons were not easily forgotten3.一般将来时的被动语态：  will be +动词的过去分词They will send cars abroad by sea.Cars will be sent abroad by sea.4.现在进行时的被动语态：   am /is /are +being +动词的过去分词We are painting the rooms.The rooms are being painted.5.现在完成时的被动语态：  have /has +been +动词的过去分词He has brought his book here.His book has been brought here.6.情态动词的被动语态：  情态动词 + be +动词的过去分词You must hand in your compositions after class.Your compositions must be handed in after class.二．主动语态变被动语态的变法：口诀：宾变主，主变宾，谓变be done ,时不变，数格必须随被变。注：1.主动、被动的时态要一致。2.主动、被动的句式要一致。3.变成的被动语态的主语与谓语在单复数上保持一致。   My aunt invited   me   to her dinner party.     主语   谓语  宾语 →I   was invited  (by my aunt ) to her dinner party.  主语   谓语         宾语三．特殊情况的被动语态：1、带双宾语的被动语态：动词+ sb(间宾) +sth(直宾)口诀：如遇双宾语，一般变间宾，若把直宾变，to /for 间宾连。1)、give/pass /show 与介词to 搭配。 give sb sth —— sb +be given sth  或 sth +be given +to sb . He gave me a book I was given a book by him.  A book was given to  me by him .2)、buy/make/cook 与介词for 搭配。 buy sb sth —— sb +be bought + sth  或 sth +be bought +for sb My mother made me a cake . I was made a cake by my mother   A cake was made for  me by my mother .2、带省to 的不定式作宾补的被动语态：动词+ sb + do sth .口诀：感使动词真叫怪，to来to去记心怀，主动语态to离去，被动语态to回来。动词：make / let /have /see /hear /feel /watch make sb do sth ----sb + be +made +to do sth The boss made the workers work all day The workers  were made to work all day by the boss.3、在see /hear /notice /keep +sb +doing sth 句型中变被动语态时，doing 不变。I heard Tom singing just now Tom was heard singing  by me just now .4.以动词短语作谓语的主动语态变被动语态时，不可丢掉后面的介词或副词。We should take care of the old . The old should be taken care of  .5、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, 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 not be answered by anybody.6、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?By whom was the story written?四．注意事项：1、有些及物动词或动词短语不能用于被动语态： last ,have ,own …..belong to ,suit…fine  ,2、不及物动词是没有被动语态： happen ,take place ,appear , hold (容纳)3、系动词是没有被动语态： Look, feel ,sound ,smell ,taste ….The dish tastes good .4、有些词组没有被动语态：sell well , write well ,ride well ,drive well This kind of skirt sells well.5、need表示需要时，后面常接doing 形式表示被动意义，相当于to be done .All the computers need repairing .=All the computers need to repaired  .6、在too…to…及enough to …结构中有时表示被动意义。The problem is too difficult to solve.    【考点剖析】考点1、一般现在时的被动语态Many accidents ________ by careless drivers every year.A．were caused B．are caused C．have caused D．caused考点2、一般过去时的被动语态A new factory ________ to deal with water pollution last month.A．built B．builds C．was built D．is built考点3、一般将来时的被动语态Many more libraries ________ in our city in the next five years.A．built B．are built C．were built D．will be built考点4、情态动词的被动语态I think students should ________ to do homework with others’ help.A．allowed B．be allowed C．allow D．be allowing         【真题演练】1．Some new airports ________ in the west of our country.
