被動語態(tài)的用法
一、概述
英語中有兩種語態(tài)，主動和被動。
例如：Many people speak English. 謂語：speak的動作是由主語many people來執(zhí)行的。 被動語態(tài)表示主語是動作的承受者，即行為動作的對象。例如：English is spoken by many people.主語English是動詞speak的承受者。 所謂主動句就是由主動態(tài)動詞(詞組)作謂語動詞的句子，而被動句則是由被動態(tài)動詞(詞組)作謂語動詞的句子。 例如：He opened the door.他開了門。(主動句) The door was opened.門被開了。(被動句)
二、被動語態(tài)的構(gòu)成
被動語態(tài)由“助動詞be+及物動詞的過去分詞”構(gòu)成。人稱、數(shù)和時態(tài)的變化是通過be的變化表現(xiàn)出來的?，F(xiàn)以teach為例說明被動語態(tài)在各種時態(tài)中的構(gòu)成。
一般現(xiàn)在時：am/is/are+taught
一般過去時：was/were+taught
一般將來時：will/shall(be going to) be+taught
現(xiàn)在進行時：am/is/are being+taught
過去進行時：was/were being+taught
現(xiàn)在完成時：have/has been+taught
過去完成時：had been +taught
過去將來時：would(was/were going to) be+taught
三、被動語態(tài)的用法
(1)不知道或沒有必要說明動作的執(zhí)行者是誰。 例如： Some more interesting novels were stolen last year. 一些新小說去年被寫了。(沒說小說是誰寫的) This book was published in 1981.這本書出版于1981年。
(2)強調(diào)動作的承受者，而不強調(diào)動作的執(zhí)行者。 例如：the window was broken by Mike.窗戶是邁克打破的。 This book was written by him.這本書是他寫的。 Eight hours per day for sleep must be guaranteed.每天8小時睡眠必須得到保證。
四、主動語態(tài)變被動語態(tài)的方法
(1)把主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語。
(2)把謂語變成被動結(jié)構(gòu)(be+過去分詞) (根據(jù)被動語態(tài)句子里的主語的人稱和數(shù)，以及原來主動語態(tài)句子中動詞的時態(tài)來決定be的形式)。
(3)把主動語態(tài)中的主語放在介詞by之后作賓語，將主格改為賓格。例如： All the people laughed at him. He was laughed at by all people. They make the bikes in the factory. The bikes are made?by them?in the factory.
五、含有情態(tài)動詞的被動語態(tài)
含有情態(tài)動詞的主動句變成被動句時，由“情態(tài)動詞+be+過去分詞”構(gòu)成，原來帶to的情態(tài)動詞變成被動語態(tài)后“to”仍要保留。
例如： We can repair this watch in two days. This watch can be repaired in two days. You ought to take it away. It ought to be taken away. They should do it at once. It should be done at once.
