文档简介
1、被动语态被动语态的构成被动语态由 “助动词 be及物动词的过去分词 ”构成。人称、数和时态的变化是 通过 be的变化表现出来的。 现以 teach为例说明被动语态在各种时态中的构成。 一般现在时: am is are taught 一般过去时: waswere taught 一般将来时: will shall be taught 现在进行时: am isare beingtaught 过去进行时: have has beentaught 现在完成时: have has beentaught注意:区分被动语态与 “be过+ 去分词 ”结构 be+过去分词 ”并不一定都是被动语态,有时是系表结构。
2、被动语态 ,动作的 对象是主语;当 “b e+过去分词 ”表示主语所处的状态时为系表结构, be是连系动 词。 be后面的过去分词是表语,相当于形容词。其区分办法如下:1, 如果强调动作或句中有介词 by 引导出动作的执行者,该句一般为被动 语态。The glass is broken.系( 表结构 )The glass was broken by the boy.被 ( 动语态 )2 ,如果句中有地点、频率或时间状语时,一般为被动语态The magazine is published in Shangha。i. ( 被动语态 ) The door is locked. (系表结构 )The
3、door has already/just been locked.被 ( 动语态 )The shop is opened. 系( 表结构 )The shop is opened at 8 a.m. everyday被. ( 动语态 )3 ,被动语态除用于一般时态和完成时态外,还可以用于其他各种时态, 而系表结构中的系动词 be 只有一般时态和完成时态。三、被动语态的用法1 不知道或没有必要说明动作的执行者是谁。 Some new computers were stolen last night. This book was published in 1981.2 强调动作的承受者,而不强调动
4、作的执行者。This book was written by him.Eight hours per day for sleep must be guaranteed.四、主动语态变被动语态的方法1 把主动语态的宾语变为被动语态的主语。2 把谓语变成被动结构 (be过去分词 ) ,根据被动语态句子里的主语的人称 和数,以及原来主 动语态句子中动词的时态来决定 be 的形式。3 把主动语态中的主语放在介词 by 之后作宾语,将主格改为宾格。 All the people laughed at him.= He was laughed at by all people.They make the
5、bikes in the factory.= The bikes are made bythemin the factory.五、含有情态动词的被动语态含有情态动词的主动句变成被动句时,由 “情态动词 be过去分词 ”构成,原 来带 to 的情态动词变成被动语态后 “to仍”要保留。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 onc
