等考点的理解。关于这些考点您可以点击下面的选项卡查看详细档案。
一般现在时的被动语态的概念:
表示的是一般现在时态和被动语态的叠合。构成:(am/is/are +done)
如:This shirt is washed once a week. 这件T恤一周洗一次。
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: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.
记忆歌诀:
宾变主,主变宾,by短语后面跟。
谓语动词变被动,be后“过分”来使用。
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。
记忆歌诀:
情态动词变动,情态加be加“过分”,原来带to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.
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:Some new computers were stolen last night.一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)
This book was published in1981.这 本书出版于1981年。
2、强调动作的承受者,而不强调动作的执行者。
例如:This book was written by him. 这本书是他写的。
Eight hours per day for sleep must be guaranteed. 每天8小时睡眠必须得到保证。
记忆歌诀:
谁做的动作不知道,说出谁做的没有必要;动作承受者需强调,被动语态运用到。
一般现在时的被动语态:
一、被动语态的结构:
主语(动作接受者)+is/am/are+动词的过去分词+(by+动作执行者)
如:Football is played in most countries in the world.
被动语态的句型总结如下:
1、肯定句:主语+be+过去分词+(by~~).
如:The boy is called Jack.
2、否定句:主语+be not+过去分词+(by~~).
如:The baby is not looked after by his father.
3、一般疑问句:Be+主语+过去分词+(by~~)?
如:Is KingLear written by Shakespeare?
4、特殊疑问句:特殊疑词+be+过去分词+(by~~)?
如:What is this kind of sweater made of?
二、被动语态的用法:
1、要表达“被…”、“受…”、“让…”、“遭…”之类的语义。
如:The teachers are well respected.
The child is well loved by people.
2、强调动作承受者。
如:He is known far and wide. 他远近闻名。
3、不知道式没有必要指出动作的执行者。
如: The room is cleaned every day. 房子每天都有人打扫。
4、为礼貌起见避免提及动作执行者。
如:I wonder if I was allowed to introduce myself? 我是否可以做自我介绍?
