被动语态复习,一、被动语态的定义： 语态是动词的一种形式，用以表示主语和谓语之间的关系。当主语是谓语动作的执行者，则为主动语态；当主语是谓语动作的承受者，则为被动语态。 被动语态由助动词be+过去分词构成，时态通过be表现出来。,二、各种时态的被动语态构成 1）一般现在时：You are required to do this. 2）一般过去时：The story was told by her. 3）一般将来时：The problem will be discussed tomorrow.,4）现在进行时：The question is being discussed in the meeting room. 5）过去进行时：The new road was being made. 6）现在完成时：The novel has been read. 7)情态动词：The rubbish can be put into the dustbin over there.,1.They make shoes in that factory.,三、主动语态变被动语态,Shoes,are made,(by them),in that factory.,一般现在时的被动语态构成 ： S(主语）+am/is /are +过去分词,2. They bought ten computers last term,Ten computers were bought (by them) last term. 一般过去时：S+was/were +过去分词,3Ling Feng can take good care of Polly ,Polly can be taken good care of by Ling Feng . 情态动词： S+ can/may/must/should + be+过去分词,4.They will finish the work in ten days.,The work will be finished (by them) in ten days. 一般将来时： S+ will+be+过去分词,5.

A new dress was made for me by my mother.,间宾（人）作被动句的主语，一切依旧；而直宾（物）作主语，则须在间宾前添加to或for。加to的动词多为give，send，bring，teach，show，pass，write，ask，tell等；加for的动词有make， draw，buy等。,二、My parents made me water all these young trees（变被动）,I was made to water all these young trees by my parents（加上了to）,这种主动句中用省to的不定式作宾补，变被动时定要加上to。这种谓语动词有feel，hear，listen to，let，make，have， see，notice，look at，watch（即常言道“一感二听三让四看见”）。,Exercises,1.People use knives for cutting things.
