【重點難點提示】
一、重點是：(1)
1 .被動語態(tài)的構(gòu)成：
助動詞be + 及物動詞的過去分詞。
助動詞be有人稱、數(shù)和時態(tài)的變化。
(1)一般現(xiàn)在時的被動語態(tài)：
am(is ,are) + 動詞過去分詞
Rice is grown in China .中國出產(chǎn)大米。
(2)一般過去時的被動語態(tài)：
Was(were) + 動詞過去分詞
These photos were taken last year .這些照片是去年照的。
(3)含有情態(tài)動詞的被動語態(tài)：
情態(tài)動詞 + be + 動詞過去分詞
This car can be mended in an hour .這輛小汽車一小時就能修好。
2 .主動語態(tài)變被動語態(tài)的方法：
(1)把主動語態(tài)的賓語優(yōu)先變?yōu)楸粍诱Z態(tài)的主語。
(2)把主動語態(tài)的謂語動詞變?yōu)楸粍咏Y(jié)構(gòu)。但時態(tài)應(yīng)保持一致，但人稱和數(shù)的形式取決于被動語態(tài)的主語。
(3)把主動結(jié)構(gòu)的主語變?yōu)榻樵~by的賓語，組成介詞短語，有時可以省略。
二、難點是：(1)被動語態(tài)的用法(即何時用被動語態(tài))。(2)主動語態(tài)變被動語態(tài)的方法(怎樣變)。
三、考點是：(1)一般現(xiàn)在時的被動語態(tài)。(2)一般過去時的被動語態(tài)。(3)含有情態(tài)動詞的被動語態(tài)。(4)將主動語態(tài)的句子變?yōu)楸粍诱Z態(tài)。有關(guān)動詞的語態(tài)在歷年各地中功課中約占3分左右。
【經(jīng)典范例引路】
例1 I think Ezhou-Huanggang Bridge up in 2003 .
A .builds B .is built C .can build D .can be built
(2001年黃岡市中功課)
簡析：此題是考查含有情態(tài)動詞的被動語態(tài)。根據(jù)賓語從句中主語Ezhou-Huanggang Bridge與謂語build up之間的關(guān)系，可以看出主語是動詞短語build up的承受者，要用被動語態(tài)。且根據(jù)說話人的語氣，只是一種推斷，表示有可能，因此要用情態(tài)動詞can。故答案為D。
例2 Do you know bananas in Hainan ?
A .grows B .is grown C .grew D .are grown
(2001年甘肅省中功課)
簡析：此題是考查一般現(xiàn)在時的被動語態(tài)。根據(jù)句意此句所填部分應(yīng)用一般現(xiàn)在時，并且根據(jù)賓語從句中主語bananas與謂語動詞grow之間的關(guān)系，可以看出主語bananas是謂語動詞grow的承受者，因此要用被動語態(tài)。且賓語從句的主語bananas為復(fù)數(shù)。故答案為D。
例3 No one knows how the huge rocks and without our modern machines eight hundred years ago .
A .are cut ,moved B .were cut ,move
C .are cut ,moving D .were cut ,moved
(2001年廣州市中功課)
簡析：此題是考查一般過去時的被動語態(tài)。在賓語從句中有表示過去的時間狀語eight hundred years ago，表明賓語從句中的謂語動詞要用一般過去時。根據(jù)主語the huge rocks與謂語動詞cut和move之間的關(guān)系，表明主語是謂語動詞的承受者，謂語動詞要用被動語態(tài)，且cut和move為并列謂語，后一個謂語應(yīng)省去助動詞be。且主語the huge rocks為復(fù)數(shù)。故答案為D。
例4 Li Lei mended the bike .(改為同義句)
The bike by Li Lei .
(2001年遼寧省中功課)
簡析：此題是考查將一般過去時主動語態(tài)的句子變?yōu)楸粍诱Z態(tài)。原句是主動語態(tài)，謂語動詞為一般過去時，被動句中的主語是第三人稱單數(shù)the bike，其答案應(yīng)為was mended。
例5 Ken is often heard to apologize to his teacher .(改為主動語態(tài))
We often Ken to his teacher .
(2001年深圳市中功課)
簡析：此題是考查一般現(xiàn)在時被動語態(tài)的句子變?yōu)橹鲃诱Z態(tài)。被動句是一般現(xiàn)在時的被動語態(tài)，主動句中的主語是先進(jìn)人稱復(fù)數(shù)，謂語動詞要用動詞原形。并且動詞hear在被動結(jié)構(gòu)中后面要接帶to的動詞不定式，但它在主動結(jié)構(gòu)中常接不帶to的動詞不定式。故答案為hear ,apologize。
