人教版初中英語語法-被動語態(tài)

中考語法精講——被動語態(tài)

我吃了一個蘋果，那現(xiàn)在蘋果怎樣了？蘋果被…蘋果被我吃了。正如漢語中的被字句，英語中的“被字句”我們稱之為被動語態(tài)。

英語中有兩種語態(tài)：主動語態(tài)和被動語態(tài)。一：英語的謂語動詞有兩種語態(tài)WespeakEnglish.主語謂語賓語主動語態(tài)主動語態(tài)表示主語是動作的執(zhí)行者。謂語speak的動作是由主語we執(zhí)行的，即主語是是謂語動詞所表示動作的執(zhí)行者。兩種語態(tài)Englishisspokenbymanypeople.主語謂語賓語被動語態(tài)主語English是謂語動詞speak所表示的動作的承受者。被動語態(tài)表示主語是動作的承受者。Wecleanourclassroomeveryday.我們每天打掃教室。

主動語態(tài)Ourclassroomiscleanedeveryday.我們的教室每天被打掃。

被動語態(tài)英語的語態(tài)是通過動詞形式的變化表現(xiàn)出來的。二、被動語態(tài)的基本構(gòu)成：

be+動詞的過去分詞（be+done)be隨著人稱，時態(tài)和數(shù)的變化而變化

1）.一般現(xiàn)在時

am/is/are+done

Wecleantheclassroomeveryday.Theclassroomiscleanedbyuseveryday.Heputonacoat.Acoatwasputonbyhim.

2）.一般過去時

was/were+doneHemadethekite.Thekitewasmadebyhim.3）.一般將來時

shall/will/begoingto+bedone

Theywillplanttreestomorrow.TreeswillbeplantedbythemtomorrowHeisgoingtowritealettertohismother.Aletterisgoingtobewrittentohismotherbyhim.4）.現(xiàn)在完成時

has/have+beendoneJimhasfinishedthework.TheworkhasbeenfinishedbyJim.

5）.含有情態(tài)動詞的被動語態(tài)can/may/must/should+bedoneIcanfindhim.Hecanbefoundbyme.三、被動語態(tài)的用法1.不知道動作的執(zhí)行者是誰。Thewindoewasbrokenlastnight.RiceisgrowninthesouthofChina.Manytreesshouldbeplantedeveryyear.每年都應(yīng)該種更多的樹。2.強(qiáng)調(diào)或突出動作的承受者，而不強(qiáng)調(diào)動作的執(zhí)行者。世界上越來越多的人說漢語。Chineseisspokenbymoreandmorepeopleintheworld.3.動作不是由人發(fā)出的。許多房屋被沖走了。Manyhouseswerewashedawaybytheflood.四、主動語態(tài)變被動語態(tài)的方法WespeakEnglish.主語謂語賓語Englishisspokenbyus.主語謂語賓語賓變主,主變賓,前加by主動語態(tài)被動語態(tài)
