被動語態(tài)講解主動句變?yōu)楸粍泳渌裱?個步驟

1、初中被動語態(tài)語法講解主動句變?yōu)楸粍泳渌裱?個步驟：1、把原主動句中的賓語變?yōu)楸粍泳涞闹髡Z2、 把動詞變?yōu)楸粍有问郊碽e +過去分詞，并注意其人稱和數(shù)隨主語的變化, 而動詞的時態(tài)則保持不變。3、 原主動句的主語如需要則放在by后面以它的賓格形式出現(xiàn)（注代詞的 賓格），如不需要則可省略。4、其它的成分（定語、狀語）不變。（一）語態(tài)分類英語動詞有兩種語態(tài).，主動語態(tài)和被動語態(tài)。主動語態(tài)表示主語是動作的執(zhí)行 者，被動語態(tài)表示主語是動作的承受者。如：They will build a new bridge over the river.（主動）A new bridge will be built o

2、ver the river.（被動）漢語中常用“被”、“給”、“由”、“受”等詞用來表示被動，而英語用： 助動詞be +及物動詞的過去分詞構(gòu)成。（二）被動語態(tài)的時態(tài)、人稱和數(shù)的變化主要體現(xiàn)在be的變化上，其形式與系動詞 be的變化形式完全一樣。一般現(xiàn)在時： am / is / are + done一般過去時： was / were + done一般將來時：shall / will + be done一般過去將來時：should / would + be done現(xiàn)在進行時： am / is / are + being + done過去進行時： was / were + being + done

3、現(xiàn)在完成時： have / has + bee n + done過去完成時： had + bee n + done將來完成時：shall / will + have been + done過去將來完成時： should / would + have bee n + done注被動語態(tài)沒有將來進行時和過去將來進行時。(三) 常見的八種時態(tài)中的被動語態(tài)1. 一般現(xiàn)在時：(1) People grow rice in the south of the country.Rice is grown in the south of the country.(2) The school doesn'

4、t allow us to enter the chemistry lab without a teacher. We are not allowed to enter the chemistry lab without a teacher.2. 一般過去時：(1) They agreed on the building of a new car factory last month.The building of a new car factory was agreed on last month.(2) The students didn't forget his lessons

5、easily.His lessons were not easily forgotten3. 一般將來時：(1)They will send cars abroad by sea.Cars will be sent abroad by sea.(2)They will give plenty of jobs to school-leavers.Plenty of jobs will be given to school-leavers.4. 過去將來時：(1)The manager said they would complete the project by the end of the y

6、ear. The manager said the project would be completed by the end of the year.(2) The workers told me they would mend the car as soon as possible.The workers told me that the car would be mended as soon as possible.5. 現(xiàn)在進行時：(1)The radio is broadcasting English lessons.English lessons are being broadca

7、sted on the radio.(2) We are painting the rooms.The rooms are being painted.6. 過去進行時：(1)The workers were mending the road.The road was being mended.(2)This time last year we were planting trees here.Trees were being planted here this time last year.7. 現(xiàn)在完成時：(1)Someone has told me the sports meeting

8、might be put off.I have been told the sports meeting might be put off.(2)He has brought his book here.His book has been brought here.8. 過去完成時：(1)When I got to the theatre, I found they had already sold out the tickets. When I got to the theatre, I found the tickets had already been sold out.(2) The

9、whole country was very sad at the news of his death; People had considered him to be a great leader.He had been considered to be a great leader(四) 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)是由“情態(tài)動詞 + be+ 及物動詞的過去分詞”構(gòu) 成。(1)You must hand in your compositions after class.Your compositions must be handed in after class.(2)

10、He can write a great many letters with the computer.A great many letters can be written with the computer by him.(五) 被 動 語 態(tài) 的 使 用1. 當(dāng)不知道或沒有必要指出動作的執(zhí)行者時， 常用被動語態(tài)，這時往往不用 by 短 語?！?Mr. White, the cup was broken after class.”2. 突出或強調(diào)動作的承受者，如果需要說出動作的執(zhí)行者，用by 短語。These records were made by John Denver.The cup

11、 was broken by Paul.3. 當(dāng)漢語句子的主語既不是動作的執(zhí)行者，也不是動作的承受者時，這時常用in+ 名詞作狀語，而代替 by 短語。These cars were made in China.（六）主動語態(tài)變被動語態(tài)的方法（ 1） My aunt invited me to her dinner party.主語 謂語 賓語f Iwas in vited （by my aunt ） to her dinner party.主語 謂語 賓語（2） The school set up a special class to help poor readers.f A specia

12、l class to help poor readers was set up in the school.1. 把主動語態(tài)的賓語變成被動語態(tài)的主語。2. 把主動語態(tài)的謂語變成被動語態(tài)的be + 過去分詞，時態(tài)要與原句保持一致。3. 把主動語態(tài)的主語變?yōu)榻樵~ by 的賓語，放在被動語態(tài)里謂語動詞之后， by 短 語可以省略。如果原句主語是地點名詞，在被動語態(tài)中用 in + 地點名詞作狀語。（七）語態(tài)轉(zhuǎn)換時所注意的問題1. 把主動語態(tài)變?yōu)楸粍诱Z態(tài)時，其謂語動詞的時態(tài)要與原句時態(tài)保持一致，其 謂語動詞的數(shù)要與新主語保持一致。We have bought a new computer.A new c

13、omputer has been bought. （正確）A new computer have been bought. （錯誤）2. 含有雙賓語的主動句變被動句時，可分別將其中的一個賓語變?yōu)橹髡Z，另一 個不動，一般變間接賓語為主語時比較多。My uncle gave me a present on my birthday.I was given a present on my birthday.如果把直接賓語 （指物 ）改為主語，則在間接賓語 （指人）前加適當(dāng)?shù)慕樵~，如 上句還可以說：A present was given to me yesterday.注意：1.一般在下列動詞后，常在間

14、接賓語前用介詞to,如：bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。（1） The book was showed to the class.(2) My bike was lent to her.2.一般在下列動詞后，間接賓語前用介詞for, 如：build, buy, cook, cut, choose, do, fetch, find, fix, get, keep, make, order, paint, play, sing 等。(1) A new skirt

15、was made for me.(2) The meat was cooked for us.(3) Some country music was played for us.3. 由動詞 + 介詞或副詞構(gòu)成的短語動詞，要把它們作為整體看，即把它們看成 一個及物動詞，介詞或副詞不可拆開或漏掉。這類動詞有： 不及物動詞 + 介詞，如 : agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about 等。The patient is being operated on.The proble

16、m is solved. It needn't be talked about.及物動詞 + 副詞：如： bring about, carry out, find out, give up, hand in, make out, pass on, point out, put away, put off, think over, turn down, work out, turn out 等。 His request was turned down.The sports meet will be put off because of the bad weather4. 帶復(fù)合賓語 (賓

17、語 + 賓補 )的動詞改為被動語態(tài)時， 一般把主動結(jié)構(gòu)中的賓語改 為主語，而賓語補足語保留在謂語動詞后面。如：(1) We always keep the classroom clean.f The classroom is always kept clea n.(2) She told us to follow her instructions. f We were told to follow her instructions.注意：在 see, watch, hear, notice, listen to, look at, make, fee等動詞后作賓語補足 語的動詞不定式都不帶to

18、,但改成被動語態(tài)后都帶to,這時不定式為主語補足 語，也就是說不定式作主語補足語不存在省略 to 的問題。We often hear him play the guitar. f He is often heard to play the guitar.5.當(dāng)主動句的主語是nobody, no one等含有否定意義的不定代詞時，被動句中 將其變?yōu)?anybody, 作 by 的賓語,并將謂語動詞變?yōu)榉穸ǖ谋粍诱Z態(tài)。如：Nobody can answer this question.誤：The questio n can be an swered by no body.正： The questi

19、on can not be answered by anybody.6. 當(dāng)否定句中的賓語是 anything, anybody, anyone等不定代詞時，在被動句中 應(yīng)將其分別變?yōu)閚othing, nobody, no on作主語，并將謂語動詞變?yōu)榭隙ǖ谋粍?語態(tài)。如：They haven't done anything to make the river clean.誤： Anything hasn't been done to make the river clean.正： Nothing has been done to make the river clean.7.

20、 以who為主語開頭的疑問句，變被動時，用by whom放在句首：Who wrote the story?誤： Who was the story written?正： By whom was the story written?8. 有些動詞既是及物又是不及物，當(dāng)它們和well, badly, easily等副詞連用時，表示主語內(nèi)在品質(zhì)或性能， 是不及物動詞， 用主動表示被動， 這時 不用被動語態(tài) ， 常見的有： write, read, clean, sell, wash, cook等。如：(1)The cloth washes easily. 這布很好洗。(2)The new produ

21、ct sells well. 這新產(chǎn)品很暢銷。對比：The books sell well. (主動句 )The books were sold out. 被( 動句 )The meat didn't cook well. (主動句 )The meat was cooked for a long time. 被( 動句 )9. 下列情況主動句 不能改為被動句 ：第一，感官系動詞 一般用主動形式表示被動意義， 如： feel， look, seem, taste, sound, remain 等。(1) Do you like the material? Yes, it feels ve

22、ry soft.誤： It is felt very soft.(2) The food tastes delicious.誤： The food is tasted delicious.(3) The pop music sounds beautiful.誤：The pop music is sounded beautiful.第二，謂語是及物動詞 leave, en ter, reach, suit, have, ben efit, lack, ow等。如：He entered the room and got his book.誤： The room was entered and his book was got.She had her hand burned.誤： Her hand was had burned.第三，一些不及物動詞短語沒有被動語態(tài)，如： take place, break out, belong to, lose heart, consist of, add up t等。如：The fire broke out in the capital building.誤： The fire was brok
