一、语态概述语态是动词的一种形式,表示句子之中主语和谓语动词的关系.英语有两种语态：主动语态和被动语态主动语态表示主语是动作的发出者（或执行者）eg：Many people speak Chinese.谓语：speak 的动作是由主语 manypeople 来执行的.被动语态表示主语是动作的承受者,即行为动作的对象.eg：Chinese is spoken by many people.主语 English 是动词speak 的承受者.二、被动语态的构成被动语态由助动词 be＋及物动词的过去分词构成.人称、数和时态的变化是通过 be 的变化表现出来的.(被动语态的否定式和疑问式均由助动词或第一个助动词构成.)各种时态的被动语态构成：1.一般现在时：am/is/are＋及物动词的过去分词I'm asked to take care of myself.Football is played all over the world2.一般过去时：was/were＋及物动词的过去分词This house was built in 1958.His leg was broken in an accident.3.一般将来时：will/shall be＋及物动词的过去分词More factories will be built in our city.He will be taken to hospital tomorrow.4.现在进行时：am/is/are being＋及物动词的过去分词.A road is being built around the mountain.Many new houses are being built in this city5.过去进行时：was/were being＋及物动词的过去分词he meeting was being held when I was there.We were being trained this time last year.6.现在完成时：have/has been＋及物动词的过去分词His book has been translated into many foreign languages.The prices of many goods have been cut again .7.过去完成时：had been + 及物动词的过去分词A new school had been set up by the end of last year.8.含有情态动词的被动语态：情态动词+be+及物动词的过去分词The rubbish can be put into the dustbin over there.三、被动语态的基本用法一般来说,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.不知道动作的执行者是谁.1).Some new computers were stolen last night.一些新电脑在昨晚被盗了.2).This bridge was founded in 1981.这座桥竣工于 1981 年.3).The front window in the classroom was broken yesterday. 昨天,教室的前窗被打2.没不...
