题组训练

一、用所给动词的正确形式填空

1.The meeting 　 will be held 　 (hold) at 3 in the afternoon.

2.Lucy 　 was forced 　 (force) to work for ten hours a day yesterday.

3.Bicycles should not 　 be ridden 　 (ride) in the playground.

4.Trees 　 are planted 　 (plant) in spring every year.

考点二　被动语态的基本用法

在被动语态中,主语是动作的承受者,主要用于下列几种情况:

1.不知道动作的执行者是谁。

This watch is made in China.这块手表是中国制造的。

2.没有必要指出动作的执行者是谁。

Many trees must be planted every year.每年必须种许多树。

3.需要强调或突出动作的承受者。

Chinese is spoken by more and more people in the world.世界上越来越多的人说汉语。(强调汉语的广泛使

用)

考点三　主动语态与被动语态的转换

(一)主动语态变为被动语态

1.要将主动句里的宾语变为被动句中的主语,若主动句中的宾语是人称代词,要将宾格变成主格。

2.把主动句中的主语变为被动句中的宾语,主格代词变成宾格代词,并由 by 引导。

3.谓语动词变成相应的被动形式。

如:

We asked him to sing an English song.(变为被动语态)→He was asked to sing an English song by us.

　　(二)带双宾语的谓语动词变为被动语态

谓语动词带双宾语时,既可以将间接宾语转化成主语,也可以将直接宾语转化成主语。若将间接宾语转

化成主语,则保留直接宾语;若将直接宾语转化成主语则保留间接宾语,且在被保留的间接宾语前加上介词 to

或for。如:

She gave me a book.(变为被动语态)→

I was given a book by her.(间接宾语 me 改为了主语)

A book was given to me by her.(直接宾语 a book 改为了主语)

　　(三)短语动词变为被动语态

许多由不及物动词和介词构成的短语动词相当于及物动词,可以有宾语,也可以有被动语态。但是短语

动词是一个不可分割的整体,在变为被动语态时,不可丢掉构成短语动词的介词。如:

We should speak to old men politely.(变为被动语态)→Old men should be spoken to politely.(to 不可省略)

　　(四)带复合宾语的动词变为被动语态

宾语加上宾语补足语一起构成复合宾语。变被动语态时,只把宾语变为被动句的主语,宾语补足语保留

在原处,成为主语补足语。如:

I heard Jane playing the piano in her room.(变为被动语态)→Jane was heard playing the piano in her room.

　　(五)变被动语态后动词形式的选择

主动句中在感官动词 see,hear,watch,notice 等及使役动词 let,make,have 等后跟省略 to 的不定式,变为被动

句时,应加上不定式符号 to。如:

He makes the girl stay at home.(变为被动语态)→

The girl is made to stay at home by him.

We often hear the girl sing in her room in the evening.(变为被动语态)→The girl is often heard to sing in her

room in the evening.

题组训练　把下列句子变成被动语态

1.Bill told me to play football with him after school.

　 I was told by Bill to play football with him after school. 　 ½

2.We can keep the book for two weeks.

　 The book can be kept by us for two weeks. 　 ½

3.Mr. Green will hold a party at his house at the weekend.

　 A party will be held by Mr. Green at his house at the weekend. 　 ½

4.Everyone should take good care of the environment.

　 The environment should be taken good care of by everyone. 　 ½

5.I often eat apples after supper.

　 Apples are often eaten by me after supper. 　 ½
