引导主语从句的词有从属连词that,whether以及连接代词who,欧阳语创编what,which,whoever,whatever,whichever呵连接副词when,where,why,how等。

)it作形式主语的从句1. It is +adj./n.+从句例如:It is a pity/shame that…遗憾的是…2. It +vi.+从句例如:It seems that…似乎…It happened that…碰巧…3. It+be+过去分词+从句例如:It said that…据说…欧阳语创编注意:“it is necessary / natural / important / stange…+that从句”这种句型里,that所引导的主语从句中谓语动词用“should+原形”,表虚拟语气。

巧用“两个要点”,确定名词性从句的连接词

巧用“两个要点”,确定名词性从句的连接词

名词性从句的连接词(引导词)是高考英语试题考查的重点,常见的连词有that,if,whether,它们在句中不作任何成分;常见的连接代词有who,whoever, what,whatever,whose,whom,which,这些连接代词在从句中可作一定的句子成分,比如可作主语、宾语、表语或者同位语等;常见的连接副词有where,why,when, how等。

为了学习和叙述的方便,把这些词统称为“连接词”。

这些“连接词”较多,且用法复杂,导致很多学生在选用时出现了错误,但是只要巧用“两个要点”,就可以很快确定出正确的“连接词”。

要点1:语法功能根据语法功能考生能够正确分析出名词性从句中缺少什么样的成分,根据缺少的成分,再根据“连接词”具体在从句中所作的语法成分,判断出应该选用什么样的“连接词”。

who与whoever在从句中作主语,whom在从句中作宾语,whose在从句中作定语,what,whatever,which,whichever在从句中可作主语、表语、定语、宾语,where在从句中作地点状语,when 在从句中作时间状语,how在从句中作方式状语,why 在从句中作原因状语,whether,if,that在从句中不作任何句子成分。

要点2:词义辨析词义辨析就是先准确掌握各个“连接词”的意义,然后能清楚地分辨出不同的“连接词”的具体意义。

能正确地辨认出不同的“连接词”的意义,是正确确定“连接词”的必要条件。

who意为“谁”,whom意为“谁”,whoever意为“无论谁,不管什么人”,相当于anyone who,其宾格形式是whomever,whose意为“谁的”;what意为“什么”,相当于“the+名词+定语从句”,whatever意为“任何事物,无论什么”,相当于“any-thing+定语从句”;which意为“哪个,哪些”,whichever 意为“无论哪个,无论哪些”,where意为“在哪里”,when意为“什么时候”,how意为“如何,多么”,可单独使用,也可后接副词或者形容词共同起连接作用,why 意为“为什么”,whether意为“是否”,that引导名词性从句时,没有意义,在引导宾语从句时常可省略。

英语名词性从句用法大全

英语名词性从句用法大全

英语名词性从句用法大全名词性从句名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。

因此,名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。

(一)引导名词性从句的连接词1、连接代词:who, whose, whom, what, which。

有词义,在从句中担任成分,如主语、表语、宾语、或定语等。

2、连接副词:when, where, why, how。

有词义,在从句中担任成分,作状语。

3、连接词:that, whether, if, as if。

that 无词义,在从句中不担任成分,有时可省略;if (whether), as if虽有词义,但在从句中不担任成分。

名词性从句的连接词选用
名词性从句包括主语从句,表语从句,宾语从句和同位语从句引导同位语从句的词通有连词that,whether,连接副词how,when,where等。

(注:if 不能引导同位语从句。

)。

在各种考试中,其最主要的考查内容为连接词的选用。

名词性从句的连接词可细分为以下四种:(1)以that来引导从句;(2)以whether/if引导从句;(3)以特殊疑问词引导从句;(4)以关系代词/副词引导从句。

一、以that引导从句
当从句的意思已完整时,名词性从句用that引导,that在从句中不作任何句子成分,仅起连接作用。

如:
It is certain that he will do well in his new job. (主语从句)
Do you know that he has been admitted to Beijing University? (宾语从句)
My decision is that we are to start at 6 tomorrow morning. (表语从句)
The news that our team had won the game excited everybody. (同位语从句)
当用that引导从句时,需注意以下情况:
1.在主语从句中,that一般不可省略,尤其是当主语从句位于句首时,它绝对不可省略。

如:
That our team had won the game was good news to us.
2.在宾语从句中,that可省略。

但当句中有两个并列的宾语从句时,引导第二个宾语从句的that不可省略。

如:
Everybody knows (that) the earth goes round the sun.
Everyone knew what happened and that she was worried.
3.当句子是以it作形式宾语时,引导宾语从句的that不可省略。

如:
He has made it clear that he will not give in.
4.that一般不能引导介词的宾语从句,偶尔可在except, but, besides和in(在于…;在…方面)的后面引导宾语从句,that不可省略。

如:
Your homework is quite good except that you have made two small mistakes.
The reason lies in that she works harder than the others do.
He differed from other people in that he always looked farther ahead in his work.
在其它介词后面需要用that引导宾语从句时,必须用it作形式宾语。

如:
You may depend on it that I shall always help you.
5.在表语从句和同位语从句中,that不可省略。

如:
My advice is that you must give up smoking right now.
The fact that he is a thief shocked all of us.
二、以whether/if引导从句
引导名词性从句的whether/if意为“是否”。

在使用时,要注意两者存在以下区别。

1.在主语从句中,whether既可引导位于句首的主语从句,也可引导用it作形式主语的主语从句,而if只能引导以it作形式主语的主语从句。

如:
Whether the work can be completed on time is doubtful.
It is doubtful whether/if the work can be completed on time.
2.在宾语从句中,当其后紧跟or not时,只能用whether,不能用if。

如:
I don’t care whether/if he comes or not.
I don’t care whether or not he comes.
3.在介词后面的宾语从句中,只能用whether,不能用if。

如:
It all depends on whether they will come back.
4.在表语从句和同位语从句中,只能用whether,不能用if。

如:
The problem is whether the money will be enough.
I have no idea whether the money will be enough.
三、以特殊疑问词引导从句
英语中所有用来构成特殊疑问句的特殊疑问词均可以用来引导名词性从句,其选择取决于从句句意的需要。

如:
It remained unknown who(谁)let out the news.
I don’t know what(什么)I was thinking of.
The problem is where(哪里)we should stay.
My question how(怎样)I shall get in touch with him has not been answered.
选择特殊疑问词需注意的情况:
1.要注意特殊疑问词在从句中所担当的句子成分:疑问代词可作主语、宾语和表语,而疑问副词(where, when, why, how)只能作状语。

如:
I can’t imagine who did it. (作主语)
I can’t imagine how he did it. (作状语)
2.Who在从句中既能作主语,也能作宾语,而whom只能作宾语。

如:
It hasn’t been decided who will manage the company.
They haven’t decided whom they should help.
四、以关系词引导从句
用关系词引导的名词性从句又可称作名词性关系从句,因为它实际上是先行词与在其后的定语从句的结合。

引导这种名词性从句的关系词有:what(=the thing that), whoever(=anyone who), whichever(=anyone/anything that), where(=the place where), when(=the time when)等。

如:What they need is a good rest.
I can judge by what I know of him.
Whoever did this job must be rewarded.
Whichever he likes will be given to him.
We shall not forget when the meeting will be held.
She walked up to where he stood.
用关系词引导名词性从句时需要注意wh-ever与no matter wh-的区别。

Wh-ever既可引导名词性从句,又可引导让步状语从句;而no matter wh-只能引导让步状语从句。

如:Whatever I said, he wouldn’t listen to me. (=No matter what I said, he wouldn’t listen to me.)(引导让步状语从句)
He would believe whatever I said. (引导宾语从句)
Whichever/No matter which you choose, the others will be offended.
Take whichever you like. 这里句中的whichever在不能用no matter what替换
最后,关于名词性从句的连接词要指出的是,根据句意,引导表语从句的还可以是as if/as though, because, as。

如:
It looks/seems as if it’s going to rain.
It was because I got up late.
Things were not as they seemed to be.
但是,当reason作主句的主语时,引导表语从句只能用that,如:
The reason for my absence was that I was ill.。
