初中被动语态语法及练习.doc

被动语态 （强化辅导）2010.10一、英语有两种语态：主动语态和补动语态主动语态表示是动作的执行者被动语态表示主语是动作的承受者Cats eat fish. （主动语态）猫吃鱼。 Fish is eaten by cats.(被动语态)鱼被猫吃。被动语态的构成由“助动词be 及物动词的过去分词”构成助动词be 有人称、数和时态的变化，其变化规则与be 作为连系动词时完全一样。1.一般现在时的被动语态：They speak English. English is spoken (by people) 2.一般过去时的被动语态：He watered the flowers just now . The flowers were watered (him )just now . 3.一般将来时的被动语态：We will clean the classroom. The classroom will be cleaned (by us ) . 4.现在进行时的被动语态：Tom is picking apples . Apples are being picking by Tom5.现在完成时的被动语态：The workers have built a house. A house has been built by the workers . 6.情态动词的被动语态：You should look after him well . He should be looked after well . 二含直接宾语和间接宾语的主动语态变为被动语态时有两种情况：1、通常把间接宾语的变为被动语态的主语，直接宾语仍保留在原位置。Tom gave me a bike last year . I was given a bike by Tom last year .My father bought me a shirt yesterday . I was bought a shirt by my father yesterday .2、把直接宾语变为被动语态的主语时，则要在间接宾语前加上介词to (make 制造，buy 变为被动时常用for )。Tom gave me a bike last year . A bike was given to me by Tom last year .My father bought me a shirt yesterday . A shirt was bought for me yesterday .三、动词短语变为被动语态时不能漏掉其中的介词或副词。You must listen to the teacher carefullly in class .The teacher must be listened to carefully in class.四、主动语态中有些动词，如：make ，have，let，see，watch，hear等后面常跟不带to的动词不定式作宾语补足语，但变为被动语态时要加to 。We often hear the boy sing in the next room . The boy is often heard to sing in the next room.四注意事项：1.不及物动词是没有被动语态：happen ,take place ,appear , hold (容纳)2.系动词是没有被动语态： Look, feel ,sound ,smell ,taste .如：The dish tastes good .3.有些词组没有被动语态：sell well , write well ,ride well 如：This kind of skirt sells well.4.need表示需要时，后面常接doing 形式表示被动意义，相当于to be done .All the computers need repairing .=All the computers need to be repaired .练习： 将下列各句改为被动语态1.He read the letter to all his friends.2.I dontgive him my books.3.He handed me the magazine.4.
