二.本周知识总结与归纳
(一)被动语态
被动语态概述
英语的语态是通过动词形式的变化表现出来的。英语中有两种语态:主动语态和被动语态。
主动语态表示主语是动作的执行者。
例如:manypeople speakchinese.
谓语:speak的动作是由主语manypeople来执行的。
被动语态表示主语是动作的承受者,即行为动作的对象。例如:chineseisspokenbymanypeople.
主语english是动词speak的承受者。
1、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speak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+spoken
一般过去时:was/were+spoken
一般将来时:will/shallbe+spoken
现在进行时:am/is/arebeing+spoken
过去进行时:was/werebeing+spoken[
现在完成时:have/hasbeen+spoken
过去完成时:hadbeen+spoken
2、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。
例如:somenewcomputerswerestolenlastnight.一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)
thisbridgewasfoundedin1981.这座桥竣工于1981年。
(2)强调动作的承受者,而不强调动作的执行者。
例如:theglasswasbrokenbymike.玻璃杯是迈克打破的。
thisbookwaswrittenbyhim.这本书是他写的。
yourhomeworkmustbefinishedontime.你们的家庭作业必须及时完成。
3、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。例如:
allthepeoplelaughedathim.
hewaslaughedatbyallpeople.
theymakethebikesinthefactory.
thebikesaremadebytheminthefactory.
hecutdownatree.
atreewascutdownbyhim.
