主動語態(tài)與被動語態(tài)初中英語知識點(diǎn)歸納
語態(tài)表示主語和謂語的關(guān)系。語態(tài)有兩種:主動語態(tài)和被動語態(tài)。如果主語是動作的執(zhí)行者,或者是說動作是由主語完成的,要用主動語態(tài),如:We speak Chinese in China.在中國我們說漢語;如果主語是動作的承受者,或者是說動作不是由主語而是由其他人完成的,則用被動語態(tài),如:Chinese is spoken by us in China.在中國漢語被我們說。
一、主動語態(tài)改成被動語態(tài)方法把主動語態(tài)改為被動語態(tài)非常簡單,可以遵循以下幾個步驟:
1. 將主動語態(tài)的賓語作被動語態(tài)的主語;
2. 謂語動詞變?yōu)閎e+及物動詞的過去分詞,并通過be的變化來表達(dá)出不同的時態(tài);
3主動語態(tài)的主語變?yōu)榻樵~by的賓語,組成介詞短語放在被動結(jié)構(gòu)中的謂語動詞之后。(有時by的短語可以省略);
例:Bruce writes a letter every week. A letter is written by Bruce every week.
二、被動語態(tài)的用法:
1. 一般現(xiàn)在時的被動語態(tài)構(gòu)成:is / am / are + 及物動詞的過去分詞 Our classroom is cleaned everyday.
2. 一般過去時的被動語態(tài)構(gòu)成:was / were + 及物動詞的過去分詞 A new shop was built last year.
3. 現(xiàn)在完成時的被動語態(tài)構(gòu)成:has / have + been + 及物動詞的過去分詞 This book has been translated into many languages.
語態(tài)復(fù)習(xí)
語態(tài)(voice)
作為一個語法范疇,是表示主語和動詞之間的主動或被動關(guān)系的動詞行式。英語動詞有兩種語態(tài):主動語態(tài)(active voice)和被動語態(tài)(passive voice)。當(dāng)主語為動作執(zhí)行者即施動者時,動詞用主動態(tài);如果主語是動作的承受者即受動者時,動詞便用被動態(tài)。例如:
(1) john helped peter.
(2) peter was helped by john.
句(1) helped是主動態(tài);句(2)was helped是被動態(tài),可見主動態(tài)是無標(biāo)記的,而被動態(tài)是有標(biāo)記的。
構(gòu)成
被動語態(tài)由助動詞be的時態(tài)之一和及物動詞的過去分詞構(gòu)成。被動語態(tài)可用于各種時態(tài),其時態(tài)變化通過助動詞be的不同形式來體現(xiàn)。如:一般現(xiàn)在時的被動態(tài)構(gòu)成形式為助動詞am/is/are + 過去分詞;而一般過去時的被動態(tài)構(gòu)成形式為was/were + 過去分詞。本冊要掌握的被動語態(tài)形式有:
一般現(xiàn)在時:am/is/are + 過去分詞
e.g. football is played all over the world.
i’m often asked to do this work.
我常常被派做這項工作。
一般過去時:was/were +過去分詞
e.g. the terracotta warriors were found in 1974 near xi’an.
they were discovered by workers in a field outside the city.
when was the building completed?
這座大樓什么時候建成的?
一般將來時:will (shall) + be +過去分詞
be going to + be + 過去分詞
e.g. the result of the exam will be known soon.
they are going to be given a difficult test.
一般過去將來時:should(would) be+過去分詞
e.g. the teacher said the results would be published soon.
he told me that the film would be shown the next week.
現(xiàn)在進(jìn)行時:am/is/are + being +過去分詞
e.g. the new airport is being built by a foreign company.

the song is being sung by the girls now.
過去進(jìn)行時:was/were being+過去分詞
e.g. the song was being sung by the girls when i got there.
the student was being criticized when i went into the
teacher’s office.
將來完成時:will have been+過去分詞
e.g. by the end of next term XX english words will
have been learned.
the building will have been built by next year.
現(xiàn)在完成時:has/have + bee n +過去分詞

過去完成時:had been+過去分詞

過去將來完成時:would have been+過去分詞
e.g. he said many words would have been learned by XX.
they promised that ten books would have been published
by the next month.
情態(tài)動詞:情態(tài)動詞 + be + 過去分詞
e.g. this road must be mended.
the machine parts may be needed in our work.
工作中可能需要這些機(jī)器零部件。
動詞不定式:to be + 過去分詞

主要用法
被動態(tài)常用于下列幾種場合:
1.當(dāng)不知道或不必提出動作的執(zhí)行者時(這時都不帶由by引起的短語);
printing was introduced into europe from china.
印刷術(shù)是從中國引入歐洲的。
the airplane was made in u.s.

2. 動作的承受者是談話的中心(這時可帶有由by引起的短語);
the song was composed by a student.

thousands of rivers are polluted in the country.
3. 出于禮貌措詞等原因而不愿說出動作執(zhí)行者是誰。
you are requested to get here in time.
請您準(zhǔn)時來這兒。
帶行為主體的被動態(tài)
行為主體就是動作的執(zhí)行者,即執(zhí)行動詞所表達(dá)的動作的人或物。在被動句中,往往不提及行為主體;但當(dāng)強(qiáng)調(diào)動作的執(zhí)行者時,可用介詞by引出行為( by +主體行為主體),置于被動態(tài)句的末尾,說明是什么人或物應(yīng)對有關(guān)事件負(fù)責(zé)。
e.g. the village was destroyed by a bomb.
這個村莊毀于炸彈。
the painting is very valuable. it was painted by van gogh.
這幅畫很值錢,它是梵高畫的。
其它用法補(bǔ)充

據(jù)報導(dǎo)所有乘客在那次飛機(jī)墜毀中遇難。
it is agreed that we will have two weeks holiday this year.
2. 用于通告標(biāo)題廣告等的被動態(tài)往往省去助動詞be。
e.g. no chinese spoken here.
shoes repaired.
famous painting stolen. 名畫被盜。
