英语：动词的语态

语态有两种:主动语态和被动语态。

主语是动作的发出者为主动语态;主语是动作的接受者为被动语态。

(1)被动语态

1) 被动语态最基本的句型结构是多唉捋胝: be +及物动词过去分词

2) 被动语态中的谓语动词一定要是及物动词

因为被动句中的主语是动作的承受者,某些短语动词如look after, think of, take care of, work out, laugh at等,也可用于被动语态。

The children were taken good care of by her.

【注意】

短语动词中的介词或副词变成被动语态时不可遗漏。

3) 主动语态变为被动语态要加“to”的情况

若宾语补足语是不带to 的不定式,变为被动语态时,该不定式前要加"to"。此类动词为感官动词,如:feel, hear, help, listen to, look at, make, observe, see, notice, watch等。例如:

The teacher made me go out of the classroom.

I was made to go out of the classroom (by the teacher).

4) 主动形式表示被动意义

如wash, clean, look, cut, sell, read, wear, feel, draw, write, sell等动词虽然用做主动形式却表示被动的意义。例如:

The food tastes good.
