中国人的思维的着眼点在动作的施动者，英美人思维的着眼点在动作的承受者，以下是主动语态变被动语态，请大家参考。

中国人常这样说：I expect you to be there on time. 我希望你准时到那里。

英美人常这样说：You are expected to be there on time. 希望你准时到那里。

这就是英语中被动语态的使用比汉语中多的原因。由于英语句子的主动语态结构不同，因而变成被动语态的方式也各不相同。

A. 主语 + 谓语 + 宾语

“主语 + 谓语 + 宾语”结构中只有一个宾语，变为被动语态时，将宾语变为主语：   They will discuss the plan at the meeting. 他们将在会议上讨论这个问题。   -- The plan will be discussed at the meeting. 这个问题将在会议上讨论。          In the past the king possessed great wealth. 过去国王拥有巨大的财富。

n        In the past great wealth was possessed by the king. 过去，巨大的财富为国王所拥有。

B. 主语+谓语+间接宾语+直接宾语

在这个句型中，谓语动词跟有两个宾语。变成被动语态时，一般将通常指人的间接宾语转化成主语，但有时也可将指物的间接宾语转化成主语：

We gave the student some books. 我们给了这个学生几本书。   -- The student was given some books. 这个学生被给了几本书。   -- Some books were given to the student. 几本书被给了这个学生。

His father bought him a computer last week. 上周他父亲给他买了一台电脑。   -- He was bought a computer by his father last week. 上周他父亲给他买了一台电脑。   -- A computer was bought for him by his father last week. 上周他父亲给他买了一台电脑。

注意：用直接宾语作被动语态的主语时，通常要在间接宾语前加上适当的介词(如to, for, of等)，以加强间接宾语的语气。

They awarded him the Nobel Prize. 他们授予他诺贝尔奖。   -- The Nobel Prize was awarded(to)him. 诺贝尔奖被授予给他。   The host had caught us some fish. 主人给我们捉了一些鱼。

n        Some fish had been caught for us by the host. 主人给我们捉了一些鱼。(for不可省) n

C. 主语+谓语+宾语+宾语补足语

在这个句型中，谓语动词后有一个宾语和一个宾语补足语，变成被动语态时，宾语转化成主语，宾语补足语也随之变为主语补足语：

All the villagers painted the houses white. 所有村民都把房子涂成了白色。

-- The houses were painted white by all the villagers. 房子都被所有的村民都涂成了白色。

They kept us waiting for a long time. 他们让我们等了很长时间。   -- We were kept waiting for a long time. 我们等了很长时间。

We regarded him as the best doctor in town. 我们认为他是城里最好的医生。   -- He was regarded as the best doctor in town. 他被认为是城里最好的医生。   注意：

有些使役动词和感官动词,如make, see, hear, watch, notice, observe, listen to等，在主动结构中跟不带to的动词不定式作宾语补足语，在变为被动结构时，不定式应加上to。   We heard him say good-bye to his friends. 我们听见他向朋友们道别。 n        He was heard to say good-bye to his friends. 他被听到向朋友们道别。 n

D. 含有情态动词的主动句变被动句

含有情态动词的谓语变成被动语态时，用“情态动词+ be done”构成。   情态动词   cancould          maymight   must   havehad to   willwould   shallshould   ought to   主动形式   cancould do   maymight do   must do

havehad to do   willwould do   shallshould do   ought to do   被动形式   cancould be done   maymight be done   must be done   havehad to be done   willwould be done   shallshould be done   ought to be done

The machine must be operated with care. 这机器必须小心操作。   Such a sentence ought not to be used here. 这个句子不应该用在这里。   What's done cannot be undone.  覆水难收。

People had to be reminded of the danger that night. 那天晚上必须提醒人们当心危险。

E. 含有“be going to do”和“be to do”等结构的主动句变被动句

含有“be going to do和 be to do 等结构的谓语动词，变成被动语态时，分别用“be going to + be done”和“be to + be done”。在这两种结构中，be只有一般现在时和一般过去时两种形式。

The problem is going to be discussed at the meeting. 这个问题将在会上讨论。   This new film is to be shown on TV next week. 这部新片下周将在电视上放映。

F.含有宾语从句的主动句变被动句

带有宾语从句的句子变成被动语态时，通常用it来作为被动句的形式主语，宾语从句保留不变。

They said that he had gone abroad to study English. 他们说他出国学英语去了。   -- It was said that he had gone abroad to study English. 据说他出国学英语去了。   We haven't decided when we should go camping. 我们还未决定什么时候去野营。

-- It hasn't been decided when we should go camping. 什么时候去野营尚未决定。   提示：

带有宾语从句的句子变成被动语态时，为了简练，还可把从句的主语变为被动句的主语，从句的谓语部分还可以变为不定式短语。

We believed that he would succeed. 我们相信他会成功。   -- He was believed to succeed. 人们相信他会成功。

Father expected that I should become an engineer. 父亲希望我成为工程师。

-- I was expected (by my father) to become an engineer. (父亲)希望我成为工程师。
