一|被動(dòng)語態(tài)的含義與結(jié)構(gòu)

英語中時(shí)態(tài)很多，但語態(tài)不多，只有兩種，即：主動(dòng)語態(tài)和被動(dòng)語態(tài)。所謂“被動(dòng)語態(tài)”，相當(dāng)于中文中常說的“被……”，“由……”的句式，如：“他的自行車被偷了。”，“這座樓房是由他們建造的。”

那么，英語中被動(dòng)語態(tài)是怎么樣構(gòu)成的呢?請(qǐng)看下面的例句：

His bicycle was stolen.

The building has been built in 2000.

通過上面的例句，可以看出，“被動(dòng)語態(tài)”的構(gòu)成是：

be + 過去分詞( + by+動(dòng)作執(zhí)行者)

二|被動(dòng)語態(tài)的運(yùn)用

什么情況下要用被動(dòng)語態(tài)呢?一般地說，有下面幾種情況：

1. 不知道誰是動(dòng)作的執(zhí)行者或沒有必要。

例如：

Paper is made from wood.

紙是由木材生產(chǎn)出來的。

The house is quite old. It was built in 1950.

這座房子太舊了。它是1950年建成的。

He was wounded in the fight.

他在戰(zhàn)斗在受傷了。

Electricity is used to run machines.

電是用來開動(dòng)機(jī)器的。

2. 需要強(qiáng)調(diào)動(dòng)作的對(duì)象時(shí)。

例如：

Calculator can't be used in the maths exam.

計(jì)算器不能用于數(shù)學(xué)考試。

Books and newspapers in the reading room mustnt be taken away.

閱覽室的書籍和報(bào)紙不準(zhǔn)帶走。

He was awarded first prize in that contest.

他在比賽中獲得了第一。

3. 為了使語氣婉轉(zhuǎn)，避免提到是誰做的這件事。

例如：

The construction of the new lab must be completed by the end of next month.

新實(shí)驗(yàn)室必須在下個(gè)月底前完工。

三|各種時(shí)態(tài)的被動(dòng)語態(tài)

一般地講，被動(dòng)語態(tài)可用于英語的各種時(shí)態(tài)。為了能準(zhǔn)確地運(yùn)用被動(dòng)語態(tài)，重點(diǎn)是要掌握be動(dòng)詞的各種時(shí)態(tài)變化。各種時(shí)態(tài)的被動(dòng)語態(tài)舉例如下：

1.一般現(xiàn)在時(shí)的被動(dòng)語態(tài)：

am / is / are + 動(dòng)詞的過去分詞

Our classroom is cleaned every day.

This car is made in China.

2.一般過去式的被動(dòng)語態(tài)：

was / were + 動(dòng)詞的過去分詞

(2)was / were +going to be + 過去分詞

He thought that your watch was going to be mended after an hour.

7.現(xiàn)在完成時(shí)的被動(dòng)語態(tài)：

have / has + been + 過去分詞

9.含情態(tài)動(dòng)詞的被動(dòng)式：

He can not be found. / I must be paid for this.

四|主動(dòng)語態(tài)與被動(dòng)語態(tài)轉(zhuǎn)換

1.從句子意義上說，就是重新找出“什么事物”是“被完成”的。

(1)主動(dòng)語態(tài)：人們說英語。

People speak English in many countries.

被動(dòng)語態(tài)：英語被說。

English is spoken in many countries..

(2) 主動(dòng)語態(tài)：我們?cè)爝@座橋。

We built this bridge last year.

被動(dòng)語態(tài)：這座橋被建造。

This bridge was built last year.

2.從語法的角度說，把原句的賓語改成主語。

(1) 主動(dòng)語態(tài)：小王邀請(qǐng)你(賓語)

Xiao Liu has invited you to a lunch party.

被動(dòng)語態(tài)：你(賓語)被邀請(qǐng)。

五|被動(dòng)語態(tài)復(fù)習(xí)要點(diǎn)

no.1

熟記結(jié)構(gòu)

助動(dòng)詞be＋及物動(dòng)詞的過去分詞

被動(dòng)語態(tài)的結(jié)構(gòu)為“”。被動(dòng)語態(tài)的不同時(shí)態(tài)是通過be的時(shí)態(tài)變化來表示的，其人稱和數(shù)方面應(yīng)與主語保持一致。其具體變化為：

一般現(xiàn)在時(shí)：am/is/are+過去分詞

一般過去時(shí)：was/were+過去分詞

一般將來時(shí)：shall /will be +過去分詞

現(xiàn)在完成時(shí)：have /has been +過去分詞

現(xiàn)在進(jìn)行時(shí)：am/is/are+being+過去分詞

過去將來時(shí)：should /would be +過去分詞

含情態(tài)動(dòng)詞的被動(dòng)結(jié)構(gòu)：情態(tài)動(dòng)詞+be+過去分詞例如：

①Chineseis spoken by the largest number of people.

②The boy was told to get supper ready after school.

③A lot of new roadsmust be built in the west of China.

no.2

明確用法

被動(dòng)語態(tài)常用于以下兩種情況：

(1) 不知道誰是動(dòng)作的執(zhí)行者，或者沒有必要指出誰是動(dòng)作的執(zhí)行者;

(2) 強(qiáng)調(diào)動(dòng)作的承受者。例如：

The treewas brokenby that boy.

這棵樹是那個(gè)男孩弄斷的。

no.3

熟練轉(zhuǎn)換

將主動(dòng)語態(tài)變被動(dòng)語態(tài)的基本方法為：

(1)

①將主動(dòng)語態(tài)的賓語作被動(dòng)語態(tài)的主語;

②謂語動(dòng)詞變?yōu)?ldquo;be+及物動(dòng)詞的過去分詞”，并通過be的變化來表達(dá)出不同的時(shí)態(tài);

③主動(dòng)語態(tài)的主語變?yōu)榻樵~by的賓語，組成介詞短語放在被動(dòng)結(jié)構(gòu)中的謂語動(dòng)詞之后。(有時(shí)by短語可以省略)。

被動(dòng)語態(tài)的一般疑問句

(2)是將一個(gè)助動(dòng)詞置于主語之前;否定句是在第一個(gè)助動(dòng)詞后加not;

特殊疑問句

的語序?yàn)椋阂蓡栐~+一般疑問句。例如：

①You must throw the broken pottery away at once.

→The broken potterymust be thrown awayat once.

②Where did they grow vegetables?

→Where werevegetables grown?

no.4

特殊情況

含雙賓語的主動(dòng)結(jié)構(gòu)

(1)變?yōu)楸粍?dòng)結(jié)構(gòu)時(shí)，有兩種方法：

①將間接賓語變?yōu)橹髡Z，直接賓語保持不變;

He told us a story.

→We were told a story(by him).

或：A story was told to us by him.

②將直接賓語變?yōu)橹髡Z，間接賓語用介詞to或for引導(dǎo)。例如：

Her mother gave her a new pen.

→A new pen was given toher by her mother.

短語動(dòng)詞

(2)的被動(dòng)語態(tài)：在變?yōu)楸粍?dòng)語態(tài)時(shí)，要將短語動(dòng)詞視為一個(gè)整體，其后的介詞或副詞不能省去。例如：

This dictionary mustn't be taken away from the library.

The children will betakengood care of (by her).

含有復(fù)合賓語的主動(dòng)結(jié)構(gòu)

(3)變被動(dòng)結(jié)構(gòu)時(shí)，通常將賓語變?yōu)楸粍?dòng)句的主語，而賓語補(bǔ)足語就成為主語補(bǔ)足語。注意：省略to的不定式作賓補(bǔ)時(shí)，不定式符號(hào)to必須補(bǔ)上。例如：

Hewas seen toswim in Qianling Lake yesterday.

不定式

(4)的被動(dòng)結(jié)構(gòu)：動(dòng)詞不定式的被動(dòng)語態(tài)為“to be +過去分詞”。例如：

The radio says a wild animal zoo is to be built in our city.

以疑問代詞開頭的疑問句

(5)轉(zhuǎn)換成被動(dòng)句時(shí)要注意詞序：應(yīng)將主動(dòng)句中的疑問代詞改為介詞by的賓語，但仍然放在句子開頭。例如：

Who has broken the cup?

→By whom has the cup been broken?

no.5

注意區(qū)別

被動(dòng)語態(tài)和過去分詞作表語的區(qū)別：

(1) 含義不同：被動(dòng)語態(tài)強(qiáng)調(diào)動(dòng)作，重點(diǎn)說明動(dòng)作由誰完成.怎樣完成;而過去分詞作表語通常用來描寫情景，敘述人或事物的特征及所處的狀態(tài)。試比較：

The window is broken.

窗子破了。(系表結(jié)構(gòu))

The window is broken by him.

窗子被他打破了。(被動(dòng)語態(tài))

(2) 用法不同：過去分詞作表語時(shí)可以被 so，very，too等程度副詞修飾，而被動(dòng)語態(tài)則不能用so，very，too修飾，而需用much，very much，so much，too much修飾。試比較：

He was very interested in science.

他對(duì)科學(xué)有極大興趣。(系表結(jié)構(gòu))

I was so much surprised at the scene that I didn't know what to do.

我被那種場(chǎng)面搞得大吃一驚，不知所措。(被動(dòng)語態(tài))
