语在复合句中起名词作用的从句叫 _________(Noun Clauses)。名词从句的功能相当于名词词组, 它在复合句中能担任____________________________
__________等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。名词性从句 名词从句 主语、宾语、表语、同位语、介词宾语1. We can use a noun clause as the
subject of a sentence.
That I can pay back the help people give me makes me happy.
Whether he’ll be able to come is not yet known.
Why they have not left yet is not
clear so far.Noun clauses We can use it as a preparatory subject.
It was good news that everyone got
back safely.
2. We can use a noun clause as the
object of a verb/preposition.
I wonder if/whether that’s a good
idea.
b) I’m interested in who that tall man is. We can use it as a preparatory
object.
We all thought it good news that the
fog had finally gone.
b) The conductor has made it clear
that no buses will be running.3. We can use a noun clause as
the predicative of be.
The truth is that the fog is too
thick for the bus to run that far.
b) My question is whether Polly can find her way home.4. We can use a noun clause in
apposition to a noun.

being watched.
b) The news that he couldn’t come
made us upset.5. We use that, if/whether or a
question word to begin a noun
clause.
No one knew if/whether he lost his sight because of an accident.
She couldn’t imagine how the blind man had found her.Read the following sentences and indicate which noun cleases they are used as. 1) That the earth is round is a fact.2) Mr Black won’t believe that her son has become a thief.
3) My idea is that we should do it right now. 4) I had no idea that you were her friend.5) How he was successful is still a puzzle.6) I had no idea where he comes from.7) The question is whether it is worth doing.8) Why he did it wasn’t quite clear.SoPASAPS名词性从句考点归纳一、名词性从句的语序(1)名词性从句构成有两种a. That + 陈述句
e.g. That he is still alive is a wonder.
他还活着,真是奇迹。
b. 疑问词+句子的剩余成分
e.g. This is what we are looking for.
这就是我们所寻找的。(2) 疑问词引导的名词性从句要求使用
陈述句语序,不能用一般疑问句
语序。他是怎么成功的仍然是个谜。How he was successful is still a puzzle.
How was he successful is still a puzzle.FT你能告诉我他住在什么地方吗?Could you tell me where he lives? Could you tell me where does he live? TF二、名词性从句连接词的选用(1) that 和what 的选用that 和 what 都可引导所有的_名词从句。但是,what除起连接作用外,还在名词性从句中充当成分,可作从句的主语、宾语或表语。而that在名词性从句中_不充当任何成分,只起连接作用。1. _____ he wants is a book.
2. _____ he wants to go there is obvious.
3. The result is ____ we won the game.4. This is _____ we want to know.
5. Is _____ he told us true?WhatThatthatwhatFill in the blanks with that or what.what6. We should pay attention to _____
the teacher is saying.7. I have no doubt _____ he will come.8. I have no idea _____ he did that
afternoon.whatthatwhat(2) if 和whether 的选用 whether和 if 都可以使用的情况:
1) 引导动词的宾语从句时;
2) 在be + adj.之后时;
3) 在主语从句中,it 用作形式主语时。只能用whether的情况:
①在非正式文体中,if ... or not 也是正确的。但与or not直接连用时,只能用whether(即whether or not),而不能用if (即if or not);
②引导表语从句和同位语从句时;③引导主语从句,且位于句首时;
④引导介词后的宾语从句时;
⑤后面直接跟动词不定式时;
⑥if引起歧义时。1. I asked her __________ she had a
bike.2. ________ we will hold a party in the
open air tomorrow depends on the
weather.if / whetherWhetherFill in the blanks with if or whether.3. We’re worried about _______ he
