cant stand being laughed at.,他忍受不了被别人嘲笑。,2,动名词的主动形式表被动含义,(1),在,want,，,need,，,require,，,deserve,等动词后，常用动名词的主动形式表达被动含义。,The radio needs repairing.,The radio needs to be repaired.,这台收音机需要修理了。,(2)be worth,后常跟动名词的主动形式表达被动含义。,The book is worth reading again.,The book is worthy of being read again.,这本书值得再读一遍。,二、现在分词的被动语态,其构成为,being/having been,过去分词。,如果现在分词所表示的动作与其逻辑主语之间是被动关系，则应用现在分词的被动形式。,The building being built is our library.,正在被建的这座楼是我们的图书馆。,Having been given the good chance,，,how could I give it up,？既然给了这么好的机会，我又怎么能放弃？,注意：当分词所表示的动作与谓语表示的动作同时发生或正在进行，则用,being,过去分词；当分词所表示的动作在谓语表示的动作之前发生则用,having been,过去分词。,【,链接训练,】,_,，,we were taken to see the library.,A,We had been shown the classrooms,B,Being shown the classrooms,C,Having been shown the classrooms,D,Having shown the classrooms,【,解析,】,考查现在分词完成时的被动语态。句意为：我们先被带领着参观了教室，又被带领着去参观图书馆。,“,看教室,”,发生在,“,看图书馆,”,之前，所以用完成时，且根据句意要用被动。,【,答案,】,C,_ in a heavy traffic jam in a taxi while you are hurrying to the airport is quite an unpleasant experience.A,Having caught B,Being caught,C,Caught D,Having been caught,【,解析,】,考查非谓语动词。句意为：当你急着去机场时遇到堵车是多么不愉快的经历啊。,being caught in,引导的动名词短语作主语，并且表示被动。句子主语为,“,_in a heavy traffic jam,”,，其逻辑主语,you,为动作的承受者，故应用动名词的被动结构，而过去分词不能作主语，所以,C,项错误。,D,项时态不正确。,【,答案,】,B,Wild animals _ and killed at such a speed that they will disappear from the earth in the near future.,A,hunt B,are hunting,C,are being hunted D,had been hunted,【,解析,】,句意为：野生动物正在以如此快的速度被捕杀以至于在不久的将来它们将会从地球上消失。根据语境,they will disappear from the earth in the near future,判断，要用现在进行时的被动语态，表示现在正在发生的事对将来可能造成的影响。,【,答案,】,C,What worried me most was _ to go abroad alone.,A,my not allowing B,having not allowed,C,my not being allowed D,my being not allowed,【,解析,】,句意为：最让我担心的是我不会被允许单独出国。考查动名词作表语，根据句意应使用被动语态，故可先排除,A,、,B,两项，通常,v,.,ing,被动式的否定式在其前加,not,，所以选,C,项。,【,答案,】,C,Research _ out supports my idea that our company should take action in no time.,A,to carry B,carrying,C,being carried D,having carried,【,解析,】,句意为：正在进行的研究证明我的观点是正确的，我们公司应该立即采取行动。,being carried out,意思是,“,正在进行,”,；是现在分词的被动形式作定语修饰,research,，意为,“,正在进行的研究,”,。,A,、,B,、,D,都没有被动之意。,【,答案,】,C,
