1、被动语态复习一、主动语态变被动语态的方法We clean the classroom every day. 主语 谓语 宾语 The classroom is cleaned (by us) every day. 主语 谓语 宾语1)把主动语态的宾语变成被动语态的主语。 2)把主动语态的谓语变成被动语态的be + 过去分词，时态要与原句保持一致。 3)把主动语态的主语变为介词by 的宾语，放在被动语态里谓语动词之后，by 短语可以省略。如果原句主语是地点名词，在被动语态中用in + 地点名词作状语。 二、被动语态常用时态的形式1)主要体现在be的变化上，其形式与系动词be的变化形式完全一样。现
2、列表如下： 一般现在时：am / is / are + P.P. 一般过去时：was / were + P.P. 一般将来时：shall / will +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 + P.P. 情态动词的被动语态： can +be+ P.P. 2) get / come /go + P.P. 这种结构多用于口语中，后面一般不接by短语 To my surprise,
3、he did not _when he fell from the tree.A. get hurt B. get hurting C. get to hurt D. get hurted3)短语动词的被动语态 动词短语是一个不可分割的整体，在变被动语态时，不可丢掉构成短语动词的介词或副词 Good care _ the children. A. must be taken of B. must be taken C. must take of D. must be taking of三、语态转换时所注意的问题1) 把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数
4、要与新主语保持一致。 We have bought a new computer. A new computer has been bought. (正确) A new computer have been bought. (错误) 2) 含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一般变间接宾语为主语时比较多。 My uncle gave me a present on my birthday. I was given a present on my birthday. 如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词，如上句还可以说： A p
5、resent was given to me yesterday. 注意：一般在下列动词后，常在间接宾语前用介词 to，如：bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。 My bike was lent to her. 一般在下列动词后，间接宾语前用介词 for, 如：build, buy, cook, cut, choose, do, fetch, find, fix, get, keep, make, order, paint, play, sing 等。 Mothe
6、r made me a new skirt. (A new skirt was made for me. ) The meat was cooked for us. 有些既不用to 也不用for, 根据动词与介词的搭配关系。 He ask me a question. (A question was asked of me. ) People all over the world know the Great Wall. The Great Wall is known to people all over the world. (不用by短语) 3)由动词+ 介词或副词构成的短语动词，要把它们
7、作为整体看，即把它们看成一个及物动词，介词或副词不可拆开或漏掉。这类动词有： 不及物动词+ 介词，如: agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about 等。 The patient is being operated on. The problem is solved. It neednt be talked about. 及物动词+ 副词：如：bring about, carry out, find out, give up, hand in, make out, pa
8、ss on, point out, put away, put off, think over, turn down, work out, turn out 等。 His request was turned down. The sports meet will be put off because of the bad weather. 4)带复合宾语(宾语+ 宾补)的动词改为被动语态时，一般把主动结构中的宾语改为主语，而宾语补足语保留在谓语动词后面。如： We always keep the classroom clean. The classroom is always kept cle
9、an. She told us to follow her instructions. We were told to follow her instructions. 注意：在see, watch, hear, notice, listen to, look at, make, feel等动词后作宾语补足语的动词不定式都不带 to，但改成被动语态后都带to，这时不定式为主语补足语，也就是说不定式作主语补足语不存在省略to 的问题。 We often hear him play the guitar. He is often heard to play the guitar. 注意：带有复合宾
10、语的句子，如果宾语补足语是名词，变被动句时，应将宾语变为主语，不要误把宾语补足语的名词作主语。如： Tomatoes were first taken back to Europe and people called them love apples. 误：Love apples were called them. 正：They were called love apples. 5)还有一种短语动词由动词+ 名词+ 介词构成，变被动语态有两种形式，如下： (1) We take good care of the books. The books are taken good care of.
11、Good care is taken of the book. (2) You must pay attention to your pronunciation. Attention must be paid to your pronunciation. Your pronunciation must be paid attention to. 用于这类结构的短语动词常见的有：catch sight of, make use of, pay attention to, set fire to, take care of, take hold of, take notice of, keep a
12、n eye on 等。 6)当主动句的主语是nobody, no one等含有否定意义的不定代词时，被动句中将其变为anybody, 作by的宾语，并将谓语动词变为否定的被动语态。如： Nobody can answer this question. 误：The question can be answered by nobody. 正：The question can not be answered by anybody. 7)当否定句中的宾语是anything, anybody, anyone等不定代词时，在被动句中应将其分别变为nothing, nobody, no one作主语，并将谓
13、语动词变为肯定的被动语态。如： They havent done anything to make the river clean. 误：Anything hasnt been done to make the river clean. 正：Nothing has been done to make the river clean. 8)以who为主语开头的疑问句，变被动时，用by whom放在句首： Who wrote the story? 误：Who was the story written? 正：By whom was the story written? 9)有些动词既是及物又是不及
14、物，当它们和well, badly, easily, smoothly等副词连用时，表示主语内在品质或性能，是不及物动词，用主动表示被动，这时不用被动语态，时态多用一般现在时或一般过去时，常见的有：carry, drive, lock, pick, shut, wear, tear, write, read, clean, sell, wash, cook, iron, burn, draw, cook, keep, cut, open, blow, peel, sell, act 等。如： The cloth washes easily. 这布很好洗。 The new product sel
15、ls well. 这新产品很畅销。 The pen writes smoothly. 这支笔写字很流畅。 对比： The books sell well. (主动句) The books were sold out. (被动句) The meat didnt cook well.
