自考英語(一)復(fù)習(xí)資料第七章(2)

　　本課主要語法：被動語態(tài)

    英語動詞有主動語態(tài)和被動語態(tài)兩種，當(dāng)主語是動作的發(fā)出者，動詞用主動語態(tài)；當(dāng)主語時(shí)動作的承受者，動詞要用被動語態(tài)。只有及物動詞才有被動語態(tài)。

    1． 被動語態(tài)的構(gòu)成：

    被動語態(tài)由“be+過去分詞”構(gòu)成。
    如：I clean the window.（主動）
   The window is cleaned by me.（被動）

    根據(jù)時(shí)態(tài)的不同，被動語態(tài)中的be動詞可以有各種變化：
    時(shí)態(tài) 主動句    被動句 be 的變化
    一般現(xiàn)在時(shí) He cleans the window. The window is cleaned by him. is
    一般過去時(shí) He cleaned the window. The window was cleaned by him. was
    一般將來時(shí) He will clean the window. The window will be cleaned by him.     will be
    現(xiàn)在進(jìn)行時(shí) He is cleaning the window. The window is being cleaned by him.     is being
    過去進(jìn)行時(shí) He was cleaning the window. The window was being cleaned by him. was being
    現(xiàn)在完成時(shí) He has cleaned the window. The window has been cleaned by him. has been
    過去完成時(shí) He had cleaned the window. The window had been cleaned by him. had been
    將來完成時(shí) He will have cleaned the window. The window will have been cleaned by him. will have been

進(jìn)行時(shí)較少用被動語態(tài)。

2．一些特殊形式被動語態(tài)的構(gòu)成：

1）不定式結(jié)構(gòu)的被動語態(tài)，有以下幾種情況：

a).表示喜歡、希望、想要及與其相似意義的動詞+賓語+不定式，由不定式的被動式構(gòu)成被動語態(tài)。如：He wants someone to take photographs. 他想找個(gè)人來照些相。（主動）
He wants photographs to be taken. 他想找個(gè)人來照些相。（被動）

b) 表示命令、請求、勸告、邀請的動詞+間接賓語+不定式，可以用主要動詞的被動式構(gòu)成被動語態(tài)。如：He invited me to go.他邀請我去。（主動）
I was invited to go.我被邀請去。（被動）

但是，如果是advise/beg/order/recommend/urge+間接賓語+不定式+賓語的結(jié)構(gòu)，則可以用兩種被動語態(tài)。一種是如上述將主要動詞變成被動語態(tài)?；蛘哂谩癮dvise等動詞+that…should+被動式” 構(gòu)成被動語態(tài)

如：He urged the Council to reduce the rates.他敦請市議會減輕捐稅。（主動）
  The Council was urged to reduce the rates.市議會被敦請減輕捐稅。（被動）
  He urged that the rates should be reduced.他敦請市議會減輕捐稅。(被動)

在句子中，動詞后面直接是不定式作賓語，沒有間接賓語，所以被動語態(tài)只有一種形式，即用that …should結(jié)構(gòu)表示被動語態(tài)。

  He decided to sell the house.他決定把房子賣了。（主動）
  He decided that the house should be sold.他決定，房子必須得賣掉。（被動）

2）動名詞結(jié)構(gòu)的被動語態(tài)：

如是advise/insist/propose/recommend/suggest+動名詞+賓語結(jié)構(gòu)，通常用that…should結(jié)構(gòu)表示被動語態(tài)。
如：He recommended using bullet-proof glass.他建議用防彈玻璃。（主動）
He recommended that bullet-proof glass should be used.他建議應(yīng)該使用防彈玻璃。（被動）
其它動名詞結(jié)構(gòu)的被動語態(tài)由動名詞的被動式來表示：
如： I remember them taking me to the Zoo.我記得他們曾經(jīng)帶我去過動物園。（主動）
I remember being taken to the Zoo.我記的被帶到動物園去過。（被動）

3）含有情態(tài)動詞的被動語態(tài)：

含有情態(tài)動詞的被動語態(tài)的結(jié)構(gòu)：情態(tài)動詞+be+過去分詞。
如：You must shut these doors.你必須把這些門關(guān)上。（主動）
   These doors must be shut.這些門必須關(guān)上。（被動）
You should have told him.你本應(yīng)該告訴他。（主動）
He should have been told.本應(yīng)該告訴他才是。（被動）

4）帶有直接賓語和間接賓語的句子，變?yōu)楸粍诱Z態(tài)的時(shí)候，只把一個(gè)賓語變?yōu)橹髡Z，另外一個(gè)賓語保留在動詞后面，這種句子可以有兩個(gè)被動句。

如：His teacher gave him a book.他的老師給了他一本書。（主動）
A book was given to him by his teacher.（被動）
He was given a book by his teacher. （被動）
Someone gave her a dog.有人送給她一只狗。（主動）
A dog was given to her. （被動）
She was given a dog. （被動）

兩種被動語態(tài)中，第二種形式比第一種形式更為常用，即應(yīng)該把間接賓語變?yōu)楸粍诱Z態(tài)的主語。

5）含有復(fù)合賓語的主動句變?yōu)楸粍泳鋾r(shí)，將賓語變?yōu)橹髡Z，賓補(bǔ)仍保留在動詞之后，成為主補(bǔ)。

如：We call him Xiao Wang.我們叫他小王。（主動）
He was called Xiao Wang.他被叫小王。（被動）
We asked the teacher to explain the sentence again.我們要求老師把這個(gè)句子再解釋一次。（主動）
The teacher was asked to explain the sentence again.老師被要求把這個(gè)句子再解釋一次。（被動）
注：make, hear, watch, see, feel, let, have等動詞在主動語態(tài)中，其后作賓補(bǔ)的不定式一般不帶to，但當(dāng)用于被動句時(shí)，后面作賓補(bǔ)的不定式必須帶有to。
如：She saw a man go into the room.她看見一個(gè)男人走進(jìn)屋里。（主動）
   A man was seen to go into the room.一個(gè)男人被看到走進(jìn)屋里去了。（被動）
   His mother made him do his homework again.他媽媽讓他把作業(yè)重寫一次。（主動）
   He was made to do his homework again by his mother.他被媽媽要求把作業(yè)重寫一次。（被動）

6）動詞短語的被動語態(tài)

動詞+介詞

如：They have talked about this matter recently.他們近來一直在談?wù)撨@件事情。（主動）
This matter has been talked about recently.這件事情近來一直被談?wù)撝＃ū粍樱?/P>

動詞+副詞

如：They put off the sports meeting.他們把運(yùn)動會推遲了。（主動）
The sports meeting was put off.運(yùn)動會被推遲了。（被動）

7)get+過去分詞構(gòu)成的被動語態(tài)

get+過去分詞也可以構(gòu)成被動語態(tài)，用這種結(jié)構(gòu)的句子側(cè)重于動作的結(jié)果而不是動作本身。
如：The man got hurt on his way home.那個(gè)男子在回家的路上受傷了。
    Mary is going to get married.瑪麗準(zhǔn)備結(jié)婚。

3．被動語態(tài)的用法：

1）動作的施動者很明顯，沒有必要提到時(shí)：
如：The rubbish hasn’t been collected.垃圾沒有清走。
Your hand will be X-rayed.你的手要照X片。

2）不知道、不確切知道或忘記了誰是施動者。
如：The minister was murdered.部長被謀殺了。
You will be met at the station.有人會到車站去接你。

3）使用被動語態(tài)可以避免說出別扭的句子。
如：When he arrived home a detective arrested him.他回到家時(shí)，一名偵探逮捕了他。（主動）

此句最好表示為：

When he arrived home he was arrested by a detective.他回到家里就被一名偵探逮捕了。（被動）變?yōu)楸粍雍螅梢员苊飧膿Q主語。

4) 主動句中主語是不定代詞one，通常可以表示為被動語態(tài)。
如：One sees this sort of advertisement everywhere.這樣的廣告到處可見。（主動）
   This sort of advertisement is seen everywhere. 這樣的廣告到處可見。（被動）

5）當(dāng)動作的實(shí)施者即主動句中的主語是泛指人們時(shí)：這樣的動詞有：assume, believe, claim, consider, estimate, find, know, report, say, think等，通?？梢员硎緸楸粍诱Z態(tài)。
如：People believe him to be honest.人們相信他是誠實(shí)的。
    He is believed to be honest.相信他是誠實(shí)的。

6）新聞報(bào)道，書刊介紹等文體中，突出描述的客觀性。
如：Three people have so far been killed in the storms sweeping across the north of England and Southern Scotland.在席卷英格蘭北部和蘇格蘭南部的暴風(fēng)雨中，三人喪生。

4．被動語態(tài)與系表結(jié)構(gòu)的區(qū)別：

英語中有些“be+過去分詞”的形式可以表示被動語態(tài)也可以作系表結(jié)構(gòu)。如果表示一個(gè)動作，則是被動語態(tài)；如果表示狀態(tài)，則是系表結(jié)構(gòu)。表示被動時(shí)，常伴有by短語；表示狀態(tài)時(shí)多用其他介詞短語（in, at, with等）

如：The novel is well written.這個(gè)小說寫得很好。（系表結(jié)構(gòu)）
The novel is written by a woman.這個(gè)小說是一位婦女寫的。（被動）
The man was offended. 那個(gè)人很生氣。（系表結(jié)構(gòu)）
The man was offended by the woman.那個(gè)男人被那個(gè)女人激怒了。（被動）

5．主動形式表被動含義：

當(dāng)句子中出現(xiàn)easy , hard , difficult 等詞修飾時(shí)，我們用主動形式表達(dá)被動
如 I found the poem hard to understand .
2001年第25小題：
They found the lecture hard --------
A to be understood B to understand C for understanding D to have been understood
答案是B

第二部分：鞏固練習(xí)
