什么叫名词性从句？

主语从句
subject clause
宾语从句
名词性从句 noun clause
object clause
表语从句
predicative clause

appositive clause
由 that 引导: 1. That we shall be late is certain. That the earth is round is known to 2. _____________________ all. That you(地球是圆的 missed the) chance 3. ________________________ is a pity.
(你错过了这次机会)
that 无意义, 后接一个完整的句子 . that 不可省
考点一:主语从句后置!
为了避免主语冗长,句子头重脚轻,经常用it作形式主语, 主语从句放在后面作真正的主语. 例:
That we shall be late is certain. -- It’s certain that we shall be late. 1. That the earth is round is known to all.
The novel tells that the truth always takes the side of the majority of people. I can’t explain why he behaves like that.
How he finished doing that is not important. Where we will go hasn’t been decided yet.
I’m not sure whether you would like it or not. She felt very surprised that I finished it all by myself. I have no idea where he is. Please tell us the truth how many people were drowned in the flood.
• It doesn’t matter if/whether he is a foreigner. • It is a question whether he is willing to come. • It is unknown how she has reduced her weight in such a short time.
It 的用法： （形式主语）
It’ possible/important/necessary/clear… that……
很可能/重要的是…/必要的是…/很清楚…
It’s said/ reported… that..据说/据报道…
It’s been announced/declared that..已经通知/宣布 … It seems/appears/happens.. that…显然、明显、 碰巧..
b. if/whether + 陈述句 No one knew if/whether he lost his sight because of an accident.
c. 疑问词+句子的剩余成分 This is what we are looking for.

That he will succeed is certain . 2) Whether he will go there is not known . 3) What he said is not true . 4) Where he hid the money is to be found out . 5) Whoever comes is welcome. 6) It’s certain that he will succeed . 7) How we can help the twins will be discussed at the meeting. 8) When they’ll start the project has not been decided yet.
