1、精品资料欢迎下载初中被动语态语法讲解一、英语动词有两种语态.，主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如：They will build a new bridge over the river. (主动) A new bridge will be built over the river. (被动) 汉语中常用 “ 被” 、“ 给” 、“ 由” 、“ 受” 等词用来表示被动，而英语用：助动词 be + 及物动词的过去分词构成。二 、被动语态的时态、人称和数的变化主要体现在be 的变化上，其形式与系动词 be 的变化形式完全一样。常见的几种时态中的被动

5、positions must be handed in after class. 三、 被 动 语 态 的 使 用1.当不知道或没有必要指出动作的执行者时，常用被动语态，这时往往不用by 短语。“ Mr. White, the cup was broken after class. ”2.突出或强调动作的承受者，如果需要说出动作的执行者，用by 短语。The cup was broken by Paul. 3.当汉语句子的主语既不是动作的执行者，也不是动作的承受者时，这时常用in + 名词作状语，而代替 by 短语。 These cars were made in China. 四、主动语态变
6、被动语态的方法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。五、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，其谓语动词的数要与新主语保持一致。We have bought a new computer.-A new computer has been bought. 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
7、为主语，另一个不动，一般变间接宾语为主语时比较多，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。My uncle gave me a present on my birthday. I was given a present on my birthday. A present was given to me yesterday. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页，共 4 页精品资料欢迎下载注意： 1.一般在下列动词后，常在间接宾语前用介词 to ，如： bring, give, hand, lend,
8、offer, pass, pay, promise, sell, show, take, teach, tell 等。(1) The book was showed to the class 。 (2) My bike was lent to her. 2.一般在下列动词后，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。(1) A new skirt was made for me. (2) The meat was
9、 cooked for us. (3) Some country music was played for us. 3. 由动词 + 介词或副词构成的短语动词，要把它们作为整体看，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： agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about ：bring about, carry out, find out, give up, hand in, make out, pass on, point out, put away
10、, put off, think over, turn down, work out, turn out等。The problem is solved. It neednt be talked about. 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：(1) We always keep the classroom clean. The classroom is always kept clean.
11、 (2) 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. 5. 当主动句的
12、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.- The question can not be answered by anybody. 6. 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，并将谓语动词变为肯定的被动语态。如：They havent done anything to make the river

14、uct sells well. 这新产品很畅销。9. 下列情况主动句不能改为被动句：第一，感官系动词一般用主动形式表示被动意义，如：feel，look, seem, taste, sound, remain 等。(1) Do you like the material? Yes, it feels very soft. 第二，一些不及物动词短语没有被动语态，如：take place, break out, belong to, lose heart, consist of, add up to等。如： The fire broke out in the capital building. 第三
