名词性从句
1. 什么叫名词性从句?
一般来说,一个句子中的主语,宾语,表语,同位语,都是由名词或名词短语充当的。所以,当一个句子中的主语,宾语,表语,同位语是由句子充当时,他们就变成了主语从句,宾语从句,表语从句和同位语从句。
The result hasn’t been declared yet.
Who will attend the meeting hasn’t been declared yet.
He knows the result.
He knows who will win the competition.
The trouble is the hard math problem.
The trouble is that I have lost his address.
I came up with an idea that I would visit my former teacher.
I came up with an idea that surprised everyone in my class.
(同位语从句的用法为:解释说明前面某个抽象名词内容的从句。常跟同位语从句的抽象名词有 fact,news,idea, truth, hope, problem,information,belief,thought,doubt,promise,question等。)
主语从句
宾语从句
表语从句
同位语从句
定语从句
名词性从句的三类连接词:(高考重点:填选正确的连接词,一定和定语从句的关系代词和关系副词区分开)
2. 高考语法填空做题方法
先找到主句的主干(找核心---谓语动词),弄清是哪种从句,再根据意思选填引导词。
Whether you'll win the game or not doesn't matter
Whoever will attend the meeting must sign your name here.
That he is a student is true.
Whatever he wants is needed by his parents.
Which is better is clear.
What we should do next is still unknown.
How we should face the hard situation is a problem.
The trouble is that I have lost his address.
That's because he didn’t understand me
That's why he got angry with me.
It sounds as if somebody is knocking at the door.
The problem is who we can get to replace her.
That was what she did this morning.
The problem is how he did it.
主语从句
表语从句
They are talking about what they like .
I don’t know if/whether he still lives here after so many years
She asked me whose handwriting was the best in the class.
I'll just say whatever comes into my mind.
Do you know when the ancient Olympic Games began
I’ve been thinking about how we can make the newspaper more interesting
I came up with an idea that I would visit my former teacher.

He put forward the question whether they should start at once·
I have no idea whose book it is .
That is a problem which skirt I should buy.

宾语从句
同位语从句
【注意】
(1)主语从句的特殊句型(it 作形式主语)
①It is +形容词+ that...
That he will win the match is certain.= It is certain that he will win the match
②It is +名词词组(no wonder难怪, an honour荣幸, a pity可惜的事, a shame 丢脸的事, a surprise令人惊讶的事, a fact事实…)+ that...
It’s a fact that we can’t go.
It is an honour that traditional handicrafts are attracting people's eyes.
It is a pity that our team lost the game.
It is a shame that she can’t understand French.
③It is +过去分词(said据说, reported据报道说, thought认为, expected预料到, announced公布说, believed相信, etc. )+ that...
It is said that she works as an actress.
It is announced that the sports meet will be held next Tuesday
④It appears/ seems that...貌似…/ It happens that...恰巧…/ It occurred to me that...突然想到/ It turned out that...结果是…
It turned out that nobody remembered the address.
(2) 宾语从句的特殊句型
①whether 和 if 都能翻译成是否,但做题永远用whether;whether还有一个特殊结构, whether…or 是…还是
whether…or not 是否
I don't know whether he will stay here or not next time.
今年高考题:To eat one, you have to decide whether ____57____ (bite) a small hole in it first, releasing the stream and risking a spill (溢出), ____58____ to put the whole dumpling in your mouth, letting the hot soup explode on your tongue.
②当 doubt后面引导宾语从句时,如果主句是否定句时,doubt 后面的宾语从句要用 that 引导;如果主句是肯定句时,doubt 后面的宾语从句要用 whether或if来引导。
I doubt whether he can help me.
They don't doubt that he can succeed.
③当 that 引导宾语从句,而且后面又有宾语补足语时,要用 it 做形式宾语,而把 that 引导的宾语从句放到后面。常这样用的动词有 feel/think/make/ consider等。如:
I feel it easy that a student master the English language.
Schools make it a rule that students should go to school on time.
(3)同位语从句的特殊情况
①当主句的谓语较短,而同位语从句较长时,同位语从句常后置。
The story goes that William Tell killed the king with an arrow
Word came that our team had won the game.
②表示“命令、建议、要求”的名词 order,demand,suggestion 等后接同位语从句时,从句的谓语要用虚拟语气,即“should +动词原形”,should 可省略。如:
The suggestion that everyone (should) make efforts to beautify our campus is necessary.
