英語中的語態(tài)分為主動語態(tài)和被動語態(tài)兩種。主動語態(tài)表示主語是動作的執(zhí)行者，而被動語態(tài)表示主語是動作的承受者。例：

The children are looked after well.

孩子被照顧得很好。

the children和look after是被動關(guān)系。

The woman looks after the children.

這位婦女照看這些孩子。（主語是look after的執(zhí)行者）

通常只有及物動詞才有被動語，但不及物動詞加上介詞后也可以有被動語態(tài)，但介詞不可以省去。今天主要復(fù)習(xí)一般現(xiàn)在時、一般過去時、一般將來時、現(xiàn)在完成時、正在進(jìn)行時和過去進(jìn)行及情態(tài)動詞的被動語態(tài)，動詞的被動語態(tài)由be＋過去分詞構(gòu)成，be隨時態(tài)改變。

一. 1. 一般現(xiàn)在時的被動語態(tài)

動詞由is/ am/ are＋動詞的過去分詞構(gòu)成。is, am, are隨人稱改變。例：

Rice is grown in the south of China.

中國的南方種水稻。

I am often told to be careful by my mother.

我經(jīng)常被媽媽告訴要小心。

Trees are planted every spring.

樹每年春天植。

2. 一般過去時的被動語態(tài)，動詞由was/ were＋過去分詞構(gòu)成。例：

The boy was hit by a car yesterday.

這個男孩昨天被車撞了。

The chairs were repaired yesterday morning.

這些椅子昨天上午修好了。

3. 一般將來時的被動語態(tài)，動詞由will/ shall＋be＋過去分詞構(gòu)成，或者由be going to be done構(gòu)成。例：

A new school will be built here next year.

一所新的學(xué)校明年將在這里建成。

The roads are going to be widened soon.

路很快就會被加寬。

4. 現(xiàn)在完成時的被動語態(tài)，由have/ has been＋過去分詞構(gòu)成。例：

The sick man has been taken to the hospital.

那個病人已經(jīng)被帶到醫(yī)院去了。

The hospitals have been built already.

這些醫(yī)院已經(jīng)被建成了。

5. 正在進(jìn)行時的被動語態(tài)，由is/ am/ are＋being＋過去分詞構(gòu)成。例：

The meeting is being had now.

會正開著。

The water is being cleaned by the workers.

水正由工人們弄干凈。

6. 過去進(jìn)行時的被動語態(tài)。was/ were＋being＋過去分詞。例：

A book was being borrowed by me at this time yesterday.

昨天這個時候我在借書。

7. 情態(tài)動詞的被動語態(tài)。情態(tài)動詞can/ may/ must/ should＋be＋過去分詞。

The work can be done tomorrow.

這個工作可以明天做。

The composition must be finished today.

今天作文必須寫完。

二. 主動語態(tài)和被動語態(tài)的轉(zhuǎn)換

主動語態(tài)和被動語態(tài)可以相互轉(zhuǎn)換，通常有以下三個步驟來完成：

（1）賓語變主語（即將主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語）

（2）變動詞（即將主動語態(tài)的動詞隨時態(tài)變成相應(yīng)的被動語態(tài)的動詞形式）

（3）加by短語（即將主動語態(tài)的主語放于by的后面，主格變賓格，有時不必指出可以省去）

例：

They speak English every day.

（主動語態(tài)）他們每天說英語。

English is spoken by them every day.

People grow cotton in the south.

Cotton is grown in the south.（by短語省去）

They cleaned the room last night.

The room was cleaned last night.

同樣被動語態(tài)變?yōu)橹鲃诱Z態(tài)正好相反，例：

Was the book written by the boy?

Did the boy write the book?

三. 帶有雙賓語及省“to”不定式作賓補(bǔ)的句子變化。

1. 帶有雙賓語的主動語態(tài)變?yōu)楸粍诱Z，通常有兩種變化，既可以提前間賓，也可以提前直賓。例：

They gave me some advice on English study.

I was given some advice on English study by them.

Some advice on English study was given to me by them.

2. 省去“to”的不定式作賓補(bǔ)變?yōu)楸粍诱Z再加“to”。例：

He made the boy work all day.

The boy was made to work all day.

I saw them come into the room.

They were seen to come into the room by me.
