Ⅲ. Grammar

一般过去时态的被动语态的构成

英语有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者,而被动语态则表示主语是动作的承受者。如:Wecleanedtheclassroom yesterday.我们昨天打扫了教室。(主动语态,主语we是clean这一动作的执行者)

Theclassroomwascleaned yesterday.

教室昨天被打扫。

(被动语态,主语the classroom是clean这一动作的承受者)

一、一般过去时被动语态

一般过去时被动语态的结构为“主语+ was /were +及物动词的过去分词(+by+动作的执行者).”。如:

Treeswereplantedlast spring.

去年春天种了树。

1. 肯定句:

主语 + was/were +及物动词的过去分词 +其他.

Paper wasinventedbyChinese people two thousand years ago.

纸是中国人在二千多年前发明的。

2. 否定句:

主语 + was/were not +及物动词的过去分词 + 其他.

Womenwerenotallowed to take part in the games at first.

开始妇女不允许参加奥运会。

3. 一般疑问句:

Was/Were +主语 +及物动词的过去分词 + 其他?

Werethesepictures drawn by your sister?

这些图片是由你妹妹画的吗?

二、被动语态的用法:

1. 不知道谁是动作的执行者,或没有必要指出谁是动作的执行者。

e.g.Englishisspoken all over the world.全世界都在说英语。

2. 需要突出或强调动作的承受者。

e.g.Thisdictionaryis used by most students.

这本字典是大多数学生在用的。

三、主动语态变被动语态应注意的问题

1. 有些短语动词相当于及物动词,变为被动句时介词或副词不能去掉。

They putoffthe meeting because of theweather.

Themeetingwas put off because of theweather.

会议因天气的缘故被推迟了。

2. 含有双宾语的主动句变为被动句时,通常把指“人”的间接宾语变为主语,指“物”的直接宾语保留不变;如果把指物”的直接宾语变为主语,则在间接宾语前加to或for。

My auntgaveme an e-dictionary yesterday.

I was givenane-dictionary yesterday.

Ane-dictionarywasgiven to me yesterday.

3. 主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to

的动词不定式,变为被动语态时应加上不定式符号to。

I saw aheavymanenter the house.

A heavy manwasseento enter the house.

4. 系动词、不及物动词或某些短语动词(happen, takeplace,come true, fall asleep…)没有被动语态。

What happenedtoMr.Brown?

布朗先生发生了什么事?

Ⅳ. Exercises

练一练

将下列句子变为被动语态。

1. He chosesixstorybooks the other day.

Six storybooks____________ by him the other day.

2. UncleLeegaveJack a large cake for he painted the wall wonderfully.

4.Werethesemachines invented by Edison?

_______Edison_______these machines?

5. The postcardwassent to Linda by Paul.

6.Americawasdiscovered by Columbus.

_______Columbus discovered _________?

Ⅴ. Practice

Work on 4a:

1. Tell Sstoreadthe sentences in 4a and rewrite the sentences using the passive voice.

2. 做题方法点拨示例:

①点拨:原句为一般过去时态,原句的谓语动词为sold,宾语为thefridge;改为被动语态时,应将the fridge作主语,谓语动词用wassold的形式。

They soldthefridgeat a low price. →

The fridgewassoldat a low price.

②点拨:分析原句的句子结构可知,stole是谓语动词,mycamera是句子的宾语;改为被动语态句时,应将my camera作句子主语,谓语动词用wasstolen的形式。

Somebodystolemycamera from my hotel room. →

My camerawasstolen from my hotel room.

学生们自主将其他三个句子变成被动语态。

3. 最后,教师与同学们一起校对答案,并对学生们有疑问的地方进行解释,或做出合理的分析点拨。
