名词性从句讲解公开课

什么叫名词性从句？
• 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
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
同位语从句
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.

• 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.

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.
