名词性从句的分类 教案

I don't know that he will give us a gift.
I don't know what he will give us.
3)比较which & what
which有范围；what无范围
All these pencil boxes are beautiful. I don't know which I should buy.
I don't know which lane the driver will turn into.
I don't know what I should buy.
What he will give you as your birthday gift is still a secret.
4)比较有无ever
有ever泛指所有；无ever有明确的指代对象
Whoever breaks the law must be punished.
I don't know who will be our new manager.
 
第三节  名词性从句的其他要点
1)主语从句中it作形式主语
主语从句中为了避免句子“头重脚轻”，常用it作形式主语。如:
It is still a question whether she will come or not.
It is strange that you should like him.
It is still unknown which team will win the match:000b5t8 4OY
2)表语从句中The reason why... is that
The reason why...is that+表语从句
The reason why he was late was that he missed the train this morning.
3)宾语从句中的否定迁移
当宾语从句的主句主语为第一人称，谓语动词为think, believe, imagine, suppose 等(且时态为一般现在时)，则若宾语从句为否定句，要将否定迁移至主句
We don't think you are here.
I don't believe he will do so.
4)同位语从句与定语从句的区别
从意义看,同位语从句是对名词的补充说明；而定语从句是对名词加以修饰和限定
It is a fact that she has done her best.同位语从句
It is a fact that you can't deny.定语从句
从语法看,同位语从句的连词that 在从句中不充当成分，不能省略:定语从句的连词that在从句中充当成分，且作宾语/表语时可以省略
The news that our team has won the game is really encouraging. 同位语从句
The news(that) he told me is really encouraging. 定语从句
5)名词性从句的虚拟
当名词性从句的主句部分出现表示建议、命令、要求的词(advise, suggest, insist, propose, request, require, demand, command, order)时，从句部分的谓语动词要用should do, should可以省略。
It is advised that young people(should) practice their handwriting
The proposal is that students (should) spend at least three hours on after-class activities every week.
I insist that she(should) do her work alone.
The suggestion came from the chairperson that the rule(should) be adopted.
