Language 被动语态 被动语态 概念理解 谓语动词的语态表示句子的主语和谓语动作之间的关系 1 当句子的主语是谓语动作的执行者时 主 谓之间的关系称为主动语态 2 当句子的主语是谓语动作的承受者时 主 谓之间的关系称为被动语态 例如 HeteachesusEnglish 主动语态 他教我们英语 OurEnglishistaughtbyhim 被动语态 我们的英语是由他教的 HespeaksEnglish 主动语态 他说英文 Englishisspokeninmanycountriesallovertheworld 被动语态 世界许多国家都讲英语 在被动语态的句子中 谓语部分的结构是be 过去分词 被动语态的句子有时态的变化 这个变化反映在be动词上 也就是说 把一个句子做成被动语态的句子 只需要写出be动词的所需时态 再加上所给动词的过去分词就行了 当然 这只是指谓语部分而言 我们知道 be动词作为一个独立的谓语动词有自己现在分词 being 和过去分词 been 那么 下面我们来看看be在各种时态中的变化形式 被动语态的结构 例如 1 EnglishisspokeninNewZealand 2 Iwasn tinvited butI vecomeanyway 3 Itisgoingtobemadebyhim 4 Hewillbetoldlateron 5 Thebuildinghasbeenbuiltforthreeyears 6 Thedishescanbewashedinhalfanhour 7 Mycarisbeingrepaired Englishisspokeninmanycountriesallovertheworld 一般现在时 世界上许多国家都讲英文 SomeTVsetsforsaleinthedepartmentstorewerestolenlastnight 一般过去时 那家商场用来出售的部分电视机昨晚被盗 Hewon tbeallowedtomarryLarrabyhisfather 一般将来时 他父亲不会让他娶拉拉为妻的 Theywouldbesenttothearmywhentheyfinishedthetraining 过去将来时 他们结束训练时将被派往部队 Theprojectisbeingcarriedout 现在进行时 这个计划正在执行中 Thecasewasbeinginvestigatedthen 过去进行时 那时这案子正在调查中 Thisnovelhasbeentranslatedintoseverallanguages 现在完成时 这本小说已被译成了几种语言 Theysaidthatproductioncostshadbeenreduced 过去完成时 他们说生产成本已经下降了 一般来说 在我们日常生活中 能用主动语态的时候就尽量不去用被动语态 只有在下列情况中我们才用被动语态 1 不清楚动作的执行者是谁 例如 Thefrontwindowintheclassroomwasbrokenyesterday 昨天 教室的前窗被打破了 2 说话人对宾语的兴趣大于对主语的兴趣 这时可用by引导出动作的执行者 例如 MyTVsetisbeingrepairedintheshop 我的电视机正在这店里修 3 出于修辞的原因 或是说为了更好地安排句子 几种特殊的被动结构 1 关于带情态动词的被动结构带情态动词的被动结构的固定句式为 情态动词 be 过去分词 例如 Thedebtmustbepaidoffbeforenextmonth 那笔债务必须在下个月前付清 Oilcanbeturnedintoenergybyburningit 油经过燃烧可变为能源 2 关于带有两个宾语的主动态变成被动态我们先来看看 带有两个宾语的主动态句子的结构 重点看谓语部分 Shesentmeanovelonmybirthday 主谓间接宾语直接宾语状语Iallowedhimanhourtofinishthework 主谓间接宾语直接宾语状语 Shesentmeanovelonmybirthday 主动 Iwassentanovelonmybirthday 被动 Anovelwassenttomeonmybirthday 被动 Mybrotherboughtmeawatchyesterday 主动 Iwasboughtawatchyesterday 被动 Awatchwasboughtformebymybrotheryesterday 被动 几种特殊的被动结构 3 关于带有复合宾语的主动态变成被动态如果将带有复合宾语 既 宾语 宾语补足语 的主动态的句子变成被动态的句子 我们只能选择原来句子的宾语作被动态句子的主语 例如 Thestorymadeuslaugh Weweremadetolaughbythestory Theyaskedmetohelpthem Iwasaskedtohelpthem Wesawthemcomingover Theywereseencomingover 几种特殊的被动结构 巩固练习 1ThePeople sRepublicofChina onOctober1 1949 A foundB wasfoundedC isfoundedD wasfound 2English inCanada A speaksB arespokenC isspeakingD
