被动语态讲解采用版ppt.ppt

被动语态（The Passive Voice),一、运用被动语态的情景(Situations) 二、被动语态的结构与时态 (Structure and Tense) 三、被动语态举例(Examples) 四、主动变被动的方法(Method) （单宾、双宾、复合宾语、宾语从句） 五、没有被动语态的动词和词组 (Verbs and Phrases) 六、Exercises,Tom broke the window. （主动语态） The window was broken by Tom. （被动语态） ,英语的谓语动词有两种语态,主动语态,被动语态,（前者表示句子的主语为动作的发出者， 后者表示句子的主语为动作的承受者。）,从以上对比可以看出，主动句中的主语Tom在被动句中 变成了短语by Tom，主动句中的宾语the window变成了被 动句中的主语。由于被动句中的主语即主动句中的宾语， 因此，只有及物动词才有被动语态。,一、运用被动语态的情景,1.被动语态结构：,be + 过去分词(PP) + (by ),2.主动变被动应注意的情况： 1.把原来的宾语提到前面作被动语态的主语; 2.把动词变成“be + 过去分词”; 3.主动语态中的主语变为介词by的宾语。,The boy broke the glass.,The glass was broken by the boy.,3.如何从主动语态变为被动语态？,1.主语 介词by 宾语 2.谓语 be+pp 3.宾语 主语,4.主动语态和被动语态结构对照表,注： 1. 被动语态的否定式和疑问式均由第一个be动词 助动词或情态动词构成。 2. 人称和时态的变化体现在be动词上，而过去分词在任何时态中都不改变。,5.被动语态举例, The Great Wall was built more than 2000 years old. A new bridge is being built across the Changjiang River. The project will (is going to) be finished next month. Many trees have been planted around the lake. Old people should be taken care of/looked after. Books cant be taken out of the library. 7.Nobody likes being laughed at. 8.Nobody likes to be laughed at.,6.被动语态应注意的问题,1. 可接双宾语的动词 带有双宾语的主动句，变被动句时，一般把“人”提前做主语；将“物”提前则要在“人”的前面加to或for. Eg: I gave him a book yesterday. - He was given a book (by me) yesterday. - A book was given to him (by me) yesterday.,2.带to不定式作宾语补足语的复合宾语,ask/tell/allow/encourage/promisesb. to do sth.结构： People should allow teenagers to choose their own clothes. Teenagers to choose their own clothes. They encourage us to plant more trees. We to plant more trees.,should be allowed,are encouraged,3、接动词原形做宾补的动词变被动语态,使役动词(let, have, make等)或感官动词(see, hear, watch,等)在主动语态中后面接的动词不定式省略to，改为被动语态时一定要补上to。 (记忆口诀：“使感动词”真奇怪，to在句中像妖怪，主动语态to走开，被动语态to回来。”) I heard him sing in the next room. -He sing in the next room. They made us do all kinds of work. -We do all kinds of work. .注：当使用see/hear/watch sb doing sth时，变为被动语态时，doing不变。如： I saw him going into the shop.(主动) He was seen going into the shop.(被动),was heard to,were made to,4、宾语从句,汉语中含有“据说”、“据悉”、“有人说”、“大家说”等常见的宾语从句句型。 Its said/ reported/believed/ that据说/报道/认为 Its suggested that有人建议 Its well known that众所周知 Its hoped that人们希望。 eg: It was reported that it rained heavily in the south of China.据报道,5、没有被动语态的动词和词组,1.不及物动词如happen appear belong to;take place;break out等无被动语态 A traffic accident _(happen) just now. 2.连系动词无被动语态，如feel smell look sound taste等。 Peking Opera _ (sound) beautiful 3.表状态的动词无被动语态，如have own fit. I have a bike.,4.wash, write, sell, wear此动词表示事物的自然属性的时候，不用被动语态,常用副词 well, easily修饰。 The book sells well . ( 这本书销路很好) This dress washes easily . ( 这衣服较好洗) The pen writes smoothly. （这支钢笔写起来很流畅）,5.need, demand, want(需要）, require, be worth等后用动名词表被动。 The desk needs repairing. The novel is worth seeing. 注意：need后可接动名词表被动，又可接动词不定式的被动形式。： The desk needs repairing. The desk needs to be repaired.,【2013江苏常州】This listening material, together with its CD-ROMs, _ well.
