注意:

a.英語動(dòng)詞中有很多既可作及物動(dòng)詞又可作不及物動(dòng)詞,如close,begin,study,leave,work,speak等.

b.不及物動(dòng)詞沒有被動(dòng)語態(tài)

附：Thepassivevoice(供教師參考，建議逐步滲透)一、語態(tài)概述二、被動(dòng)語態(tài)的構(gòu)成三、被動(dòng)語態(tài)的用法四、主動(dòng)語態(tài)變被動(dòng)語態(tài)的方法五．主動(dòng)語態(tài)的注意事項(xiàng)英語中有兩種語態(tài)：主動(dòng)語態(tài)和被動(dòng)語態(tài)。主動(dòng)語態(tài)表示主語是動(dòng)作的執(zhí)行者。巧記為：主動(dòng)、主動(dòng)、主主動(dòng)。被動(dòng)語態(tài)表示主語是動(dòng)作的承受者，即行為動(dòng)作的對象。巧記為：被動(dòng)、被動(dòng)、主被動(dòng)。一、語態(tài)概述被動(dòng)語態(tài)由“助動(dòng)詞be＋及物動(dòng)詞的過去分詞”構(gòu)成。人稱、數(shù)和時(shí)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(dòng)語態(tài)在一般現(xiàn)在時(shí)態(tài)中的構(gòu)成。二、被動(dòng)語態(tài)的構(gòu)成口訣1：被動(dòng)語態(tài)be字變，過去分詞跟后面。一般現(xiàn)在時(shí)：am／is／are＋taught1、不知道或沒有必要說明動(dòng)作的執(zhí)行者是誰。e.g.Somenewcomputerswerestolenlastnight.

一些新電腦在昨晚被盜了。(不知道電腦是誰偷的)Thisbookwaspublishedin1981.這本書出版于1981年。2、強(qiáng)調(diào)動(dòng)作的承受者，而不強(qiáng)調(diào)動(dòng)作的執(zhí)行者。e.g.Thewindowwasbroken

byMike.窗戶是邁克打破的。

Thisbookwaswritten

byhim.這本書是他寫的。三、被動(dòng)語態(tài)的用法口訣2：誰做的動(dòng)作不知道，說出誰做的沒有必要；動(dòng)作承受者需強(qiáng)調(diào)，被動(dòng)語態(tài)運(yùn)用到。1、把主動(dòng)語態(tài)的賓語變?yōu)楸粍?dòng)語態(tài)的主語。2、把謂語變成被動(dòng)結(jié)構(gòu)(be＋過去分詞)(根據(jù)被動(dòng)語態(tài)句子里的主語的人稱和數(shù)，以及原來主動(dòng)語態(tài)句子中動(dòng)詞的時(shí)態(tài)來決定be的形式)。3、把主動(dòng)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：

Allthepeople

laughed

at

him.

He

waslaughed

at

byallthepeople.四、主動(dòng)語態(tài)變被動(dòng)語態(tài)的方法口訣3：賓變主，主變賓，by短語后面跟。謂語動(dòng)詞變被動(dòng)，be后“過分”來使用。

1.不及物動(dòng)詞和詞組不用被動(dòng)語態(tài).Thatpendoesn’tbelongtoMary.2.及物動(dòng)詞詞組在被動(dòng)語態(tài)中不可丟掉的詞組中的介詞.Theblindboyshouldbetakengoodcareof.3.主動(dòng)結(jié)構(gòu)的主語變?yōu)榻樵~by的賓語,組成介詞短語,在被動(dòng)結(jié)構(gòu)中位于動(dòng)詞之后;但在動(dòng)作執(zhí)行者無須說明或不必強(qiáng)調(diào)時(shí),by短語可省略.
