名词性从句

一.主语从句：由引导词引导，在复合句中作主语

引导词：   连词   that  whether(只引导不担当)

         连接代词  who  whoever(anyone who)  what(all that/the thing that) whatever  which  whichever（即引导又担当，主 宾 表）

          连接副词   why   when  where   how（即引导又担当，状）

It is very important that everybody should obey the laws.

What he said at the meeting is important.( All that he said is important.)

Whoever leaves the office should turn off the light.(Anyone who leaves the office should …)

When the meeting will be held has not been decided.(It has not been decided when …)

二.表语从句：由引导词引导，在复合句中作表语（在be 动词后）

引导词：同上

That is what we should do.

三.宾语从句：由引导词引导，在复合句中作宾语（动词、介词后）

引导词：同上 （只在连词栏加一 if）

动宾：I doubted if he can speak English.

I think it necessary that we should learn a foreign language.

They want to know what he said.

介宾：It depends on whether the weather looks good.

      特殊情况（介词后一般不用that 宾从，但 but  besides  except  in 后可以）

      I could say nothing but that I was sorry.

时态一致：主句过去时，从句要用相应过去时

He said that he had ever read the book.

四.同位语从句：由引导词引导，在复合句中作同位语（修饰同位名词）

    引导词：连词  that  whether(只引导不担当)

同位名词：fact  idea  faith  question 等抽象名词

The idea that we invited him yesterday is wise.(与定从的区别)

The question whether we will go to the park hasn’t been settled.

五. 注意事项

1.that只有引导宾从时可省

He said( that )he had ever read the book.

If 只能引导宾从.whether 能引导所有名从

The question is if he can come.

介词后只能用 whether 表是否不能用if

It depends on whether the weather looks good.

2.所有名从都是陈述语序
