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
  • 主语从句

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?


主语从句的概念:

如果一个句子在复合句中充当一个主语,那么这个句子就是主语从句。主语从句通常由从属连词that,whether,if和连接代词what,who,whichwhatever,whoever以及连接副词how,when,where,why等词引导。that在句中无词义,只起连接作用。


主语从句用法:

1、主语从句的引导词:
主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导:
如:That he is still alive is a wonder. 他还活着,真是奇迹。
        When we arrive doesn't matter. 什么时候到没有关系。
        What we need is money. 我们需要的是钱。
        What I want to know is this. 我想知道的就是这一点。
        Whether they would support us was a problem. 他们是否会支持我们还是一个问题。

2、主语从句与形式主语it:
有时为了考虑句子平衡,通常在主语从句处使用形式主语it,而将真正的主语从句移至句末。这分三种情况:
(1)对于以连词that引导的主语从句,通常用形式主语代主语从句:
如:It's a pity that he didn't come. 很遗憾他没来。
(2)对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从句:
如:Whether they would support us was a problem. 他们是否会支持我们还是一个问题。  
        It was a problem whether they would support us. 他们是否会支持我们还是一个问题。
(3)对关系代词型what引导的主语从句,通常不用形式主语,总是主语从句放在句首:
如:What we need is money. 我们需要的是钱。
        What I want to know is this. 我想知道的就是这一点。
(4)如果句子是疑问句,则必须用带形式主语it的结构:
如:Is it true that he is the girl's father? 他是那女孩的父亲,是真的吗?
        How is it that you are late again? 你怎么又迟到了?

3、连词that的省略问题:
引导主语从句的连词that有时可省,有时不能省,其原则是:
若that引导的主语从句直接位于句首,则that不能省略;
若that引导的主语从句位于句末,而在句首使用了形式主语it,则that则可以省略:
如:That you didn't go to the talk was a pity. 很遗憾你没去听报告。(that不可省)
        It was a pity(that) you didn't go to the talk. 很遗憾你没去听报告。(that可省)


主语从句应注意的几个问题:

1、that引导的主语从句既可放在句首,也可放在句尾,但在下列情况下that从句不可提前。
(1)在It is said/reported...that结构中:
如:It is reported that a bank was robbed yesterday.
(2)在Ithappened/occurred...结构中:
Ithappenedthattheteacherwasnotintheofficethatday.
(3)含主语从句的复合句是疑问句时:
如:Is it ture that you will give up the job?
2、下面这种情况常用it作形式主语。在It doesn't matter+what/whatever…结构中。
如:It doesn't matter what you say.
3、由what引导的主语从句谓语动词单复数问题 what引导的主语从句一般按单数对待,但是,在实际使用中究竟按单数还是按复数对取决于其成分的含义。
如:What we need is more time.
        What were left behind were five empty bottles.
