被動(dòng)語(yǔ)態(tài)
A.熟記結(jié)構(gòu)
被動(dòng)語(yǔ)態(tài)的結(jié)構(gòu)為“助動(dòng)詞be+及物動(dòng)詞的過(guò)去分詞(p.p)”。被動(dòng)語(yǔ)態(tài)的不同時(shí)態(tài)是通過(guò)be的時(shí)態(tài)變化來(lái)表示的,其人稱和數(shù)方面應(yīng)與主語(yǔ)保持一致。其具體變化為:
一般現(xiàn)在時(shí):am/is/are+p.p.
一般過(guò)去時(shí):was/were+p.p.
一般將來(lái)時(shí):shall /will be +p.p.
現(xiàn)在完成時(shí):have /has been +p.p.
現(xiàn)在進(jìn)行時(shí):am/is/are+being+p.p.
過(guò)去將來(lái)時(shí):should /would be +p.p.
含情態(tài)動(dòng)詞的被動(dòng)結(jié)構(gòu):情態(tài)動(dòng)詞+be+p.p.例如:
① Chinese ______ by the largest number of people.
A.speak
B.is speaking
C.speaks
D.is spoken

核心知識(shí)
B.明確用法
被動(dòng)語(yǔ)態(tài)常用于以下兩種情況:
1.不知道誰(shuí)是動(dòng)作的執(zhí)行者,或者沒(méi)有必要指出誰(shuí)是動(dòng)作的執(zhí)行者;
2.強(qiáng)調(diào)動(dòng)作的承受者。例如:
這棵樹(shù)是那個(gè)男孩弄斷的。
The tree ______ ______ by that boy.(2001四川江油)
(填was broken)
C.熟練轉(zhuǎn)換
1.將主動(dòng)語(yǔ)態(tài)變被動(dòng)語(yǔ)態(tài)的基本方法為:
①將主動(dòng)語(yǔ)態(tài)的賓語(yǔ)作被動(dòng)語(yǔ)態(tài)的主語(yǔ);
②謂語(yǔ)動(dòng)詞變?yōu)椤癰e+及物動(dòng)詞的過(guò)去分詞”,并通過(guò)be的變化來(lái)表達(dá)出不同的時(shí)態(tài);
③主動(dòng)語(yǔ)態(tài)的主語(yǔ)變?yōu)榻樵~by的賓語(yǔ),組成介詞短語(yǔ)放在被動(dòng)結(jié)構(gòu)中的謂語(yǔ)動(dòng)詞之后。(有時(shí)by短語(yǔ)可以省略)。
2.被動(dòng)語(yǔ)態(tài)的一般疑問(wèn)句是將一個(gè)助動(dòng)詞置于主語(yǔ)之前;否定句是在第一個(gè)助動(dòng)詞后加not;特殊疑問(wèn)句的語(yǔ)序?yàn)椋阂蓡?wèn)詞+一般疑問(wèn)句。例如:
① You must throw the broken pottery away at once.
The broken pottery ______ ______ ______ ______ at once.(同義句)
(填m ust be thrown away)(2002廣州)
② Where did they grow vegetables?(改為被動(dòng)語(yǔ)態(tài))
Where ______ vegetables ______ ?(2002福州)(填were;grown)
D.注意特例
將主動(dòng)語(yǔ)態(tài)變被動(dòng)語(yǔ)態(tài)應(yīng)注意幾個(gè)特殊情況:
1.含雙賓語(yǔ)的主動(dòng)結(jié)構(gòu)變?yōu)楸粍?dòng)結(jié)構(gòu)時(shí),有兩種方法:
①將間接賓語(yǔ)變?yōu)橹髡Z(yǔ),直接賓語(yǔ)保持不變;
②將直接賓語(yǔ)變?yōu)橹髡Z(yǔ),間接賓語(yǔ)用介詞to或for引導(dǎo)。例如:
① He told us a story.(變被動(dòng)語(yǔ)態(tài))
→We were told a story(by him).或:A story was told to us by him.
② Her mother gave her a new pen.(變被動(dòng)語(yǔ)態(tài))
A new pen ______ ______ ______ her by her mother.
(填was given to)(2001黔江)
2.短語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài):在變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí),要將短語(yǔ)動(dòng)詞視為一個(gè)整體,其后的介詞或副詞不能省去。例如:
① This dictionary mustn't ______ from the library.
A.take away
B.taken away
C.a(chǎn)re taken away
D.be taken away
[D](2001北京東城)
② She will take good care of the children.(變被動(dòng)語(yǔ)態(tài))
The children will ______ ______ ______ ______ ______ (by her).
(填be taken good care of)(2002鹽城)
3.含有復(fù)合賓語(yǔ)的主動(dòng)結(jié)構(gòu)變被動(dòng)結(jié)構(gòu)時(shí),通常將賓語(yǔ)變?yōu)楸粍?dòng)句的主語(yǔ),而賓語(yǔ)補(bǔ)足語(yǔ)就成為主語(yǔ)補(bǔ)足語(yǔ)。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:
Someone saw him swim in Qianling Lake yesterday.(變被動(dòng)語(yǔ)態(tài))
He ______ ______ ______ swim in Qianling Lake yesterday.
(填was seen to)(2002貴陽(yáng))
4.不定式的被動(dòng)結(jié)構(gòu):動(dòng)詞不定式的被動(dòng)語(yǔ)態(tài)為“to be +過(guò)去分詞”。例如:
The radio says a wild animal zoo is to ______ in our city.
A.be building
B.build
C.be built
D.built
[C](2002杭州市)
5.以疑問(wèn)代詞開(kāi)頭的疑問(wèn)句轉(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(wèn)代詞改為介詞by的賓語(yǔ),但仍然放在句子開(kāi)頭。例如:
Who has broken the cup?(改為被動(dòng)語(yǔ)態(tài))
→By whom has the cup been broken?
典型例題
E.注意區(qū)別
被動(dòng)語(yǔ)態(tài)和過(guò)去分詞作表語(yǔ)的區(qū)別:
1)含義不同:被動(dòng)語(yǔ)態(tài)強(qiáng)調(diào)動(dòng)作,重點(diǎn)說(shuō)明動(dòng)作由誰(shuí)完成、怎樣完成;而過(guò)去分詞作表語(yǔ)通常用來(lái)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(yǔ)態(tài))
2)用法不同:過(guò)去分詞作表語(yǔ)時(shí)可以被 so,very,too等程度副詞修飾,而被動(dòng)語(yǔ)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(yǔ)態(tài))

2.be made of由……制作(發(fā)生物理變化)
