被动语态小结.doc

初中英语被动语态小结一、语态概述 英语中有两种语态:主动语态和被动语态。 主动语态表示主语是动作的执行者。例如:Many people speak Chinese. speak的动作是由主语many people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。例如: English 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（p.p.）构成。人称、数和时态的变化是通过be的变化表现出来的。被动语态在各种时态中的构成。 一般现在时:am/is/are+ p.p. 一般过去时:was/were+ p.p 一般将来时:will/shall be+ p.p 现在进行时:am/is/are being+ p.p 过去进行时:was/were being+ p.p 现在完成时:have/has been+ p.p 过去完成时:had been + spoken 情态动词的被动语态,由情态动词+be+p.p构成不定式的被动语态：to be + p.pThere are twenty more trees to be planted.特殊情况: 1.主： The teacher asked li Ping to clean the floor.（ask sb.to do sth.）被：Li Ping was asked to clean the floor2.主：He made the boy work for two hours yesterday.（make sb.

He cant be laugh at by us. 4、不能用于被动语态的及物动词或动词短语：fit, marry, wish, cost, agree with, arrive at / in, succeed in, happen to, take part in, belong to 5、系动词无被动语态： be, become, fall, feel, get, keep, look, remain, seem, smell, sound, stay, taste, turn 1) It sounds good.2) The steel feels cold 6、“be+过去分词”并不
