名词性从句讲练
一、名词性从句的定义、种类及引导词。
在句子中起名词作用的句子叫名词性从句 (Noun Clauses)。 名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词性从句又可分为主语从句、宾语从句、表语从句和同位语从句。名词性从句的引导词有连接词(5个):that、if/whether(是否),as though和 as if. 连接代词(9个):what, whatever, who, whoever, whom, whomever, whose, which, whichever. 连接副词(7个):when, where, how, why, whenever, wherever, however.
1、主语从句:作句子主语的从句叫主语从句。主语从句通常由从属连词that,whether和连接代词what,who,which,whatever,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,不能省略;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。
That she will do well in her exam is certain. 她将考得好是肯定的。
What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
Where the English evening will be held has not yet been announced.
英语晚会将在哪里举行还没有宣布。
2、宾语从句:作句子宾语的从句叫宾语从句。通常由从属连词that,whether, if和连接代词what who,which,whatever,whoever以及连接副词how,when,where,why等词引导。
He told us that he felt better.
I doubt whether he will succeed.
She wondered what he had done.
Tom wanted to know where the meeting would be held.
3、表语从句:作句子表语的从句叫表语从句。引导表语从句的连词与引导主语从句的连词大致一样,表语从句位于连系动词后,有时用as if引导。其基本结构为:
主语 + 系动词(be/seem/remain/look/appear,etc)+表语从句。
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
4、同位语从句
作句子同位语的从句叫同位语从句,同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导,不能省略。可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
注意:当主语是reason时,表语从句要用that引导而不是because。
The reason why he was late was that he missed the train by one minute this morning.
(活学活用)请说出下面句子中画线部分的连接词和该从句在句子中充当的成分。
1、Oliver believes that with a million pound bank note a man could survive a month in London. ( Unit 3 ,Book3)
2、I wonder if you’d mind us asking a few questions ( Unit 3, Book3)
3、The earth became so violent that it was not clear whether the shape would last or not.
( Unit 4, Book3)
4、What is even more important is that as the earth cooled down, water began to appear on its surface. ( Unit 4, Book3)
5、The fact is that I earned my passage by working as an unpaid hand. ( Unit 3, Book3)
6、The thought that they could cross the whole continent was exciting. ( Unit 5, Book3)
7、His eyes stare at what is left of the brother’s dinner on table. ( Unit 3, Book3)
二、考点荟萃
考点1、主语从句常用it作形式主语,而把主语从句置于句末。常用句型如下:
(1)It + be + 名词(an honor, a good thing, a pity, no surprise,no wonder,etc.) + that从句 It is a pity that you didn’t go to see the film.
(2)It + be + 形容词(natural,true,obvious,god,wonderful,likely,possible,certain,etc.) + that从句
It is certain that she will do well in her exam
(3)It + be +动词的过去分词(believed,said,reported,thought,expected,arranged,etc.) + that从句 It is said that he has arrived in Beijing.
(4)It + seem/happen/appear等不及物动词 + that 从句
It happened that she was out that day.
(例题)___ is a fact that English is being accepted as an international language. (NMET 1995)
A. There B. This C. That D. It
答案D。当名词从句在句中作主语时,为避免句子头重脚轻,常用it作形式主语置于句首,而将真正的主语从句放在句尾。此时it只起先行引导作用,本身无实义。此句也可以改写为:That English is being accepted as an international language is a fact.
考点2、it 在宾语从句中的运用:
1)动词 + it + 宾补(形容词、过去分词或名词) + that 结构
I think it important that we should keep calm.
He’s made it clear that he won’t agree to the plan.
We find it necessary that we practise English daily.
I heard it said that she had gone abroad.
She made it a duty that she takes care of her sick mother.
2)介词 /动词+ it + that的特殊结构(it 作引导词)
You may depend on it that they’ll support you.
I take it that you don’t agree with me.
You can count on it that he is very smart.
I shall see to it that he is taken good care of
(例题)
考点3、名词性从句中what与 that的区别
that引导的名词性从句表事实,在从句中不充当句子成分;what引导的名词性从句表疑问,在句中充当主语、宾语或表语。
I want to know what you are going to do tomorrow.
I know that you’re better now.
(例题)—I think it is going to be a big problem.
—Yes, it could be.
—I wonder ______ we can do about it. (北京 2002春季)
A、if B、how C、what D、that
答案C。本题考察名词性从句的连接词的用法。wonder后面应跟宾语从句,而从句中的谓语动词do是及物动词,可见从句缺少一个代替宾语的成分,我们可以用排除法排除不作成分的if和that,再排除引导方式状语的how,答案是C,句子的意思是“我们能就此做些什么”。
考点4、名词性从句的语序应用陈述语序:主语+谓语
(例题)He asked ____ for a violin.(NMET1992)
A. did I pay how much B. I paid how much C. how much did I pay D. how much I paid
答案:D。名词性从句应用陈述语序。
考点5、宾语从句的时态呼应
当主句动词是现在时,从句根据自身的句子情况,而使用不同时态。当主句动词是过去
(could/ would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时,过去完成时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用一般现在时态。
I know (that) he will study English next year. (从句用一般将来时)
I know he has studied English since 1998. (从句用现在完成时)
The teacher told us that Tom had left us for America.(从句用过去完成时)
(例题)The teacher told us that the earth round the sun.
A. goes B. went C. is going D. had gone
答案:A. 当从句表示的是客观真理,科学原理,自然现象,则从句仍用一般现在时态。
考点6、that 不可省略的情况
1) 由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个或以后几个分句前的that不能省略。
2) 作介词but、except、in等的宾语时不可省。
3) 在主+谓+it(形式宾语)+宾补+that从句(真正宾语) 的句型中不省略。
4) that引导的同位语从句、表语从句和主语从句。
We must make it clear that we mean what we say.
He has told me(that)he will go to Shanghai tomorrow.
We must never think (that) we are good in everything and that others are good in nothing.
I know nothing about him except that he is from the north.
(例题) made them happy.
A. Their son had passed the entrance exam B. That their son had passed the entrance exam
C. What their son had passed the entrance exam D. Why their son had passed the entrance exam
答案:B. 该题考查的是名词性从句的引导词,主语从句意思完整,因此用that。that引导的主语从句时,that 不能省略。
考点7、同位语从句和定语从句的区别:
that作为关系代词,可以引导定语从句,在定语从句中充当主语、宾语,在从句中作宾语时可以省略; that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
I had no idea that you were here.(that引导同位语从句,不能省略)
Have you got the idea(that)this book gives you of life in ancient Greece?
(that引导定语从句,作give的直接宾语,可以省略)
考点8、只用whether的情况,不用if 的情况:
1)在动词不定式之前 I can’t decide whether to stay here .
2)在whether …or not 的固定搭配中 I want to know whether it’s good news or not .
3)在介词后,只能用whether。 His father is worried about whether he lose his work .
4)同位语从句、表语从句;主语从句位于句首及宾语从句放在句首表示强调时
They are investigating the question whether the man is trustworthy(同位语)
Whether the plan is feasible remains to be proved. (主语从句位于句首)
The point is whether we should lend him the money. (表语)
Whether this is true or not, I really don’t know. (宾语从句放在句首表示强调)
(活学活用)用Whether or if填空:
1. The question is ____ people will buy it.
2. ________ it is true remains a question.
3. She doubts ___ she will be successful .
4. The question ________ it is right or wrong depends on situation.
5. We don’t know _________ or not she was ready.
6. She hasn’t decided ________ to go.
7. It all depends on _________ they will support us.
考点9、疑问词+ever和no matter+疑问词的区别:
1)疑问词+ever(无论…..)可以引导名词性从句和让步状语从句。
Whoever breaks the rule must be punished. (名词性从句,作主语)
Whoever breaks the rule , he must be punished (让步状语从句,作状语)
= No matter who breaks the rule, he must be punished
2)no matter+疑问词只能引导让步状语从句
No matter who breaks the rule, he must be punished.
(例题)Sarah hopes to become a friend of ______shares her interests. (Shanghai1995)
A. anyone B. whomever C. whoever D. no matter who
答案为C。本题句子的意思是:Sarah希望跟自己有共同爱好的人交朋友。疑问词+ever引导的名词性从句与no matter+疑问词引导的从句的区别是:前者既可以引导名词性从句也可以引导让步状语从句;后者只能引导让步状语从句。首先排除A和D,从句中需要的是主语,所以whomever也不行。
考点10、宾语从句中的虚拟语气、否定前移
1)在demand、order、suggest、decide、insist, desire, request, command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。
I insist that she (should) do her work alone. 我坚持要她自己工作。
2)宾语从句的否定前移。think, believe, imagine, suppose等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式,即将从句中的否定形式移到主句中。
We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so, will he 我相信他不会这样做,是吗?
(例题)I don’t think a warm winter always has a negative influence on our life, ?
A. doesn’t it B. don’t I C. hasn’t it D. has it
答案为D.I/We think, believe, imagine, suppose等结构引导的宾语从句时,反意疑问句疑问部分与宾语从句一致,而宾语从句又否定前移,因此答案为D。
