2、” 构成;人称、数和时态的变化是通过be 的变化表现出来的; 被动语态的否定式和疑问式均由助动词或第一个助动词构成; 各种时态的被动语态构成:1. 一般现在时: amis are 及物动词的过去分词 Eg:Im asked to take care of myself. Football is played all over the world 2. 一般过去时: waswere及物动词的过去分词 Eg:This house was built in 1958. His leg was broken in an accident. 3. 一般将来时: will shall be及物动词的过去分
3、词 Eg:More factories will be built in our city. He will be taken to hospital tomorrow. 4. 现在进行时: amis are being 及物动词的过去分词 . Eg:A road is being built around the mountain.

5、Eg:The rubbish can be put into the dustbin over there. 三、被动语态的基本用法 一般来说,在我们日常生活中,能用主动语态的时候就尽量不去用被动语态;只有在以下情形 中我们才用被动语态:1. 不知道动作的执行者是谁;eg:1.Some new computers were stolen last night.一些新电脑在昨晚被盗了;名师归纳总结 - - - - - - -第 1 页,共 13 页精选学习资料 - - - - - - - - - 学习必备 欢迎下载2.This bridge was founded in 1981.这座桥竣工于
6、1981 年;3.The front window in the classroom was broken yesterday. 2. 没不要说出动作的执行者是谁;昨天,教室的前窗被打Eg:1.The time-table has been changed .时间表已变动了2.China was founded in 1949. 3. 不情愿说出动作的执行者,其目的是为了使语言得体、圆滑等;在这种情形下,有经常用一些句式,如 It is said that (据说 ),It is reported that (据报道 ),It is well known that (众所周知 )It is s
7、upposed that (据估计说 ) ,It is believed that 大家信任, It is hoped that 大家期望, It is thought that 大家认为, It is suggested that 据建议等等 ;eg:1.It is said that she is going to be married to a foreigner.据说她要嫁给一个外国人; 2.It is said that the boy has passed the national exam. said to have passed the national exam. )4. 强
8、调动作的承担者,而不强调动作的执行者;Eg:1.The glass was broken by Mike. 2.his book was written by him.玻璃杯是迈克打破的;这本书是他写的;( The boy is 3).Your homework must be finished on time. 你们的家庭作业必需准时完成;注:使用被动语态的情形口诀:动作谁做的不知道,谁说出的不必要;接受动作需强调,用被动语态最为妙;四、主动语态变被动语态的方法:1. 把主动语态的宾语变为被动语态的主语;2. 把谓语变成被动结构 be 过去分词 依据被动语态句子里的主语的人称和数,以及原先主
9、动语态句子中动词的时态来打算 be 的形式 ;3. 把主动语态中的主语放在介词 by 之后作宾语,将主格改为宾格;He plant trees in sping . Trees are planted in sping by him . 主动语态变被动语态口诀:宾语提前主语变,原主变宾by 后见,时态人称be 关键;All the people laughed at him. They make the bikes in the factory. He was laughed at by all people. The bikes are made by them in the factory
10、. He cut down a tree. A tree was cut down by him. 被动语态中“by+宾语” 的省略:被动语态句式中的“by+宾语” 表示及物动词所表示动作的执行者,但是在遇到以下情形时,表示 动作执行者“by+宾语” 经常被省略;1. 动作执行者不确定时 Eg:1.Paper is made from wood . 2.Many people are killed in traffic accidents every day . 2. 不必说明动作执行者时 Eg:1.English is also spoken as the second language a
11、s well as one of the official languages . 2.Football is played in most school . 3. 动作执行者为一般大众时 .

12、子结构为“ 主语 +谓语 +宾语(唯独宾语)” 时,把宾语提到句首做主语,然后把谓语改成被动语态形式,最终把原主语变为宾格至于介词by 之后;实际运用中by 短语常被省略;Eg:1.We finish our homework in the evening . 2.Our homework is finished in the evening . 2. 当句子结构为“ 主语 +谓语 +间接宾语 表示人的 +直接宾语(表示物的)” 时,一般把间接宾语变为主语,而直接宾语不变,这样句子显得自然些;假如把直接宾语作为主语,那么在间接宾语 前应加介词 to 或 for. Eg:1.She sent m
13、e a novel on my birthday. 主动 被动 I was sent a novel on my birthday. 被动 A novel was sent to me on my birthday. 被动 2.My brother bought me a watch yesterday. 主动 I was bought a watch yesterday. 被动 A watch was bought for me by my brother yesterday.留意:1. 间接宾语前需要加for 的动词,offer 等;,returnbuy ,sing ,catch ,fin
14、d ,get,drow ,cook ,keep ,make2. 间接宾语前需要加to 的动词,thow ,lend,send ,take ,teach ,tell bring ,give ,pass ,hand ,leave ,show ,write 等3. 当句子结构为“ 主语 +谓语 +宾语+宾语补足语”把主动态变成被动态时,只需将主动语态的宾语变为被动语态句子的主语,而原句里的宾语补足语现在就变成被动态句子的 主语补足语 了eg:1.They asked me to help them. I was asked to help them. 2.Now people can use com
15、puters to help them . comouter can be used to help them . 3.We must keep the room clean . 4.We saw them coming over. The room must be kept clean .

The little boy was let to go home . 4. 含有情态动词的被动语态含有情态动词的主动语态变成被动语态时,由“ 情态动词 be过去分词” 构成, 原先带 to 的情态动词变成被动语态后“to ” 仍要保留;Eg: We can repair thi
17、s watch in two days. This watch can be repaired in two days. They should do it at once. It should be done at once. The rubbish can be put into the dustbin over there. 5. 短语动词的被动语态:一般说来,只有及物动词才有被动语态,但很多“ 不及物动词+副词或介词” 构成的短语动词,相当于及物动词,也可以有被动语态,但变被动语态后,不行把介词或副词漏掉;Eg:1.He turned on the radio just now. Th
