含有情态动词的被动语态是由 情态动词 be 及物动词的过去分词 构成 agreatmanyletterscanbewrittenwiththecomputerbyhim hecanwriteagreatmanyletterswiththecomputer 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 thecupwithmixturewasbrokenafterclass 只是告诉老师杯子坏了 不知是谁弄坏的 或不想说出谁弄坏的 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 theserecordsweremadebyjohndenver thecupwasbrokenbypaul 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 thesecarsweremadeinchina 15 000carswillbeproducedeachyearinthenewfactory 1 myauntinvitedmetoherdinnerparty 主语谓语宾语 iwasinvited bymyaunt toher主语谓语宾语dinnerparty 2 theschoolsetupaspecialclasstohelppoorreaders aspecialclasstohelppoorreaderswassetupintheschool 主动语态变被动语态的方法 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 语态转换时要注意的问题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 wehaveboughtanewcomputer anewcomputerhasbeenbought 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 myunclegaveonmybirthday wasgivenonmybirthday 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 apresentwasgiventomeyesterday 保留宾语 me apresent apresent i 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 如 thecupwithmixturewasshowedtotheclass mybikewaslenttoher 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 play sing等 如 mothermademeanewskirt anewskirtwasmadeforme themeatwascookedforus somecountrymusicwasplayedforus heaskedmeaquestion aquestionwasaskedofme peopleallovertheworldknowthegreatwall thegreatwallisknowntopeopleallovertheworld 不用by短语 有些既不用to也不用for 根据动词与介词的搭配关系 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 lookafter thinkof talkabout等 thepatientisbeingoperatedon theproblemissolved itneedn tbetalkedabout 及物动词 副词 如 bringabout carryout findout giveup handin makeout passon pointout putaway putoff thinkover turndown workout turnout等 hisrequestwasturneddown thesportsmeetwillbeputoffbecauseofthebadweather 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 wealwayskeeptheclassroomclean theclassroomisalwayskeptclean shetoldustofollowherinstructions weweretoldtofollowherinstructions 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 weoftenhearhimplaytheguitar 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 tomatoeswerefirsttakenbacktoeuropeandpeoplecalledthemloveapples 误 loveappleswerecalledthem 正 theywerecalledloveapples thebooksaretakengoodcareof goodcareistakenofthebooks 1 wetakegoodcareofthebooks 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 attentionmustbepaidtoyourpronunciation yourpronunciationmustbepaidattentionto 2 youmustpayattentiontoyourpronunciation 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 7 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 noone作主语 并将谓语动词变为肯定的被动语态 如 theyhaven tdoneanythingtomaketheriverclean 误 anythinghasn tbeendonetomaketheriverclean 正 nothinghasbeendonetomaketheriverclean 8 以who为主语开头的疑问句 变被动时 用bywhom放在句首 whowrotethestory 误 whowasthestorywritten 正 bywhomwasthestorywritten 9 有些动词既是及物又是不及物 当它们和well badly easily等副词连用时 表示主语内在品质或性能 是不及物动词 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 theclothwasheseasily 这布很好洗 thenewproductsellswell 这新产品很畅销 thepenwritessmoothly 这支笔写字很流畅 对比 thebookssellwell 主动句 thebooksweresoldout 被动句 themeatdidn tcookwell 主动句 themeatwascookedforalongtimeoverlowheat 被动句 10 下列情况主动句不能改为被动句 第一 感官系动词一般用主动形式表示被动意义 如 feel look seem taste sound remain等 doyoulikethematerial yes itfeelsverysoft 误 itisfeltverysoft thefoodtastesdelicious 误 thefoodistasteddelicious 误 thepopmusicissoundedbeautiful thepopmusicsoundsbeautiful 第二 谓语是及物动词leave enter reach suit have benefit lack own等 如 误 theroomwasenteredandhisbookwasgot 误 herhandwashadburned heenteredtheroomandgothisbook shehadherhandburned 误 thefirewasbrokeoutinthecapitalbuilding 第三 一些不及物动词短语没有被动语态 如 takeplace breakout belongto loseheart consistof addupto等 如 thefirebrokeoutinthecapitalbuilding 第四 不及物动词没有被动语态 如 rise happen succeed remain lie等 whenwegottothetopofthemountain thesunhadalreadyrisen aftertheearthquake fewhousesremained 误 thesunhadalreadybeenrisen 误 aftertheearthquake fewhouseswereremained 第五 宾语是反身代词 相互代词 同源宾语 不定式 v ing形式及抽象名词等 不能变为被动句子的主语 如 itaughtmyselfenglish weloveeachother 误 myselfwastaughtenglish 误 eachotherisloved 11 在汉语中 有一类句子不出现主语 在英语中一般可用被动结构来表示 例如 据说 itissaidthat 据报导 itisreportedthat 据推测 itissupposedthat 希望 itishopedthat 众所周知 itiswellknownthat 普遍认为 itisgenerallyconsideredthat 有人建议 itissuggestedthat 1 itisreportedthatitisgoingtoraintomorrow 2 itiswellknownthatthomasedisoninventedtheelectriclamp 在英语语言中 被动语态是极常见的语言现象 人们进行语言交际 离不开对被动语态的使用 熟练掌握被动语态也为下一步学习打下良好的基础 在动词 ing形式 不定式等结构中 都有被动式 都需要运用被动语态的知识去理解 一些常见的不能变为被动语态的动宾词组 catchacold感冒eatone swords食言loseheart丧失信心losepatience失去耐心makeaface做鬼脸makeupone smind下决心makebed铺床makeroomfor为 腾出地方 keepwatch守望keepsilence保持安静speakone smind表明见解takeplace发生takeone stime从容不迫 别着急takeoffice就职takeone
