Grammar

英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如： 

Many people read this novel. 

(主动语态，主语Many people是read这一动作的执行者)

This novel is read by many people. 

(被动语态，主语This novel是read这一动作的承受者)

用法

（1）不知道或没必要说明动作的执行者是谁。

Paper is made from wood.

（2）需要强调动作的承受者。

He was awarded the first prize.

（3）出于礼貌等方面的考虑不愿说出动作的执行者。

He was asked to give a talk about how to learn English well.

（4）用于表示“据说/据报道/人们相信”等的固定句式。

Translation:

据说我们将在校园里使用机器人。

It’s said that robots will be used in our school. 

人们相信健康重于财富。

It is believed that health is above wealth.

被动语态的注意事项如下：

(1) there be结构没有被动语态。

(2) happen，rise，appear，come out等不及物动词（短语）没有被动语态。

(3)主动句中宾语为反身代词的没有被动语态。

(4) look，sound，smell 等系动词或sell，write, wash等表示主语内在“品质”或“性能”的不及物动词可以用主动语态表示被动含义。e.g. These books sell well.这些书卖得很好。

(5) talk about，pay attention to，take care of 等动词短语在变为被动语态时，其中的介词不可遗漏。e.g. She takes good care of her daughter. 

Her daughter is taken good care of by her.

她把女儿照顾得很好。

(6)在主动语态中，see，watch，hear等感官动词和使役动词make后接省略to的动词不定式，但在变为被动语态时，要把省略的to还原。

e.g. I saw my boss buy some postcards. 

→My boss was seen to buy some postcards by me.

我看见我的老板买了一些明信片。

(7)双宾语结构改为被动语态时，若直接宾语作主语，动词后要加上介词；若间接宾语作主语，则动词后不用加介词。

My teacher gives me some advice.

→ Some advice is given to me by my teacher.

→I am given some advice by my teacher.

我的老师给我许多建议。
