        help我們都知道是幫助的意思,可是你知道help的被動(dòng)語(yǔ)態(tài)to需要還原嗎?下面是學(xué)習(xí)啦小編為你整理的help被動(dòng)語(yǔ)態(tài)的相關(guān)資料,希望大家喜歡!

        help的被動(dòng)語(yǔ)態(tài)

        help的被動(dòng)語(yǔ)態(tài)to需要還原

        例句:I help my mother do the housework

        因?yàn)橹鲃?dòng)態(tài)里只是省略了TO的動(dòng)詞不定時(shí)。被動(dòng)態(tài)要還原。

        my mother is helped by me to do the housework.

        類(lèi)似的還有see sb .do sth. sb. is seen to do sth.

        help

        vt.& vi.幫助; 有助于, 有利于;

        vt.治療; 避免; 招待(客人); 給…盛(飯、菜)

        n.幫助; 助手; 補(bǔ)救辦法; 有用

        vi.(在餐桌旁)招待,侍應(yīng),作仆人(或店員、服務(wù)員等);

        int.[呼救語(yǔ)]救命!;

        被動(dòng)語(yǔ)態(tài)的用法

        1、不知道或沒(méi)有必要指出誰(shuí)是動(dòng)作的執(zhí)行者時(shí)。

        The bridge was built last year.這座橋是去年建造的。

        He was elected chairman.他被選為主席。

        2、 當(dāng)更加強(qiáng)調(diào)動(dòng)作的承受者時(shí)。此時(shí)動(dòng)作的執(zhí)行者由by引導(dǎo)置于謂語(yǔ)動(dòng)詞之后,不需要時(shí)可以省略。

        The room hasn't been cleaned yet.房間還沒(méi)有打掃。

        The tiger was killed by him.老虎被他殺死了。

        3、當(dāng)動(dòng)作的執(zhí)行者不是人時(shí),多用被動(dòng)語(yǔ)態(tài)。如:

        The window was blown by wind.窗戶(hù)被風(fēng)吹開(kāi)了。

        The whole village has been washed away by the flood.整個(gè)村莊都被洪水沖走了。

        4、表示客觀的說(shuō)明常用"It is + 過(guò)去分詞."句型。

        It is said that Lucy has gone abroad.據(jù)說(shuō)露茜已經(jīng)出國(guó)了。

        It is believed that he is a spy. (=He is believed to be a spy.)大家相信他是個(gè)間諜。

        其它常見(jiàn)的"It is + 過(guò)去分詞+ that"句型還有

        It is reported that…據(jù)報(bào)道

        It is said that…據(jù)說(shuō)

        It is believed that…大家相信

        It is suggested that…有人建議

        被動(dòng)語(yǔ)態(tài)的構(gòu)成

        被動(dòng)語(yǔ)態(tài)由“助動(dòng)詞be+及物動(dòng)詞的過(guò)去分詞”構(gòu)成。人稱(chēng)、數(shù)和時(shí)態(tài)的變化是通過(guò)be的變化表現(xiàn)出來(lái)的?,F(xiàn)以teach為例說(shuō)明被動(dòng)語(yǔ)態(tài)在各種時(shí)態(tài)中的構(gòu)成。

        一般現(xiàn)在時(shí):am/is/are+taught

        一般過(guò)去時(shí):was/were+taught

        一般將來(lái)時(shí):will/shall(be going to) be+taught

        現(xiàn)在進(jìn)行時(shí):am/is/are being+taught

        過(guò)去進(jìn)行時(shí):was/were being+taught

        現(xiàn)在完成時(shí):have/has been+taught

        過(guò)去完成時(shí):had been +taught

        過(guò)去將來(lái)時(shí):would(was/were going to) be+taught
