怎样理解名词性从句、定语从句和状语从句？

The question is when they won the game. 表语从句

When they won the game is the question. 主语从句

I have the question when they won the game. 同位语从句

I wonder when they won the game. 宾语从句

表语、主语、同位语和宾语通常由名词充当，所以表语从句、主语从句、同位语从句和宾语从句统称为名词性从句。

Do you know the time when they won the game? 定语从句

定语通常由形容词充当，所以定语从句也叫形容词从句

When they won the game, I had just finished my job. 状语从句

状语通常由副词充当，所以状语从句也叫副词性从句。

结论：从句的分类是依据其在主句中的句子成分而定的。

三类从句的引导词有所不同

定语从句引导词有：疑问代词和疑问副词（但不包括what和how）

名词性从句引导词：①所有定语从句使用的引导词；

②what和how；

③少量连词：whether/if, as if/though;

④以-ever结尾的疑问词：whatever, whenever等

状语从句引导词有：①所有连词；

②以-ever结尾的疑问词：whatever, however等

定语从句引导词数量最少，状语从句引导词最多。名词性从句引导词与定语从句引导词最接近（但范围更大），状语从句引导词与定语从句引导词差别最大。状语从句引导词与名词性从句引导词有部分交叉（以-ever结尾的疑问词）。另外，when 和where是这三类从句有可以使用的公共引导词。

引导词的理解

定语从句引导词没有自己的字面意义，只有指代意义：指代先行词，也就是说引导词意义等于先行词词义；但名词性从句和状语从句引导词不同，它们都具有自

己固定的字面意义。

Of all the books, I don’t know which is the best for me.

which引导名词性从句，意为：哪一个

Can you pick out the book which is the best for me?

which引导定语从句，指代the book

Put the book where you can find it easily.

where引导状语从句，意为：在…….地方

I know where you put the book.

where引导宾语从句，意为：在哪里

I’ve found out the shelf where you put the book. where引导定语从句，指代the shelf

但that引导名词性从句作为特例既无意义也不作句子成分，完全是“聋子的耳朵是个配佐”。

引导词的省略：一般引导词都不能省，只有极少数时候可以省略，即使可省自己造句时也最好不要省（省略形式一般看作不规范文体）。

定语从句：which/that/whom在从句中作宾语时可省，作其它成分不可省。Can you lend me the book (that/which)you are reading? 可省

Can I read the book that/which belongs to you? 不可省

名词性从句：只有that引导宾语从句时可省，其它时候和其它任何名词性从句引导词都不能省(因为它们都具有特定意义)。

I know (that) he is an honest man. 可省

That he is an honest man is well-known. 不可省，即使它既无意义也无成分状语从句：只有if引导条件状语从句时可省，但从句必须倒装。

If it should rain tomorrow, I would have to stay at home.

= Should it rain tomorrow, I would have to stay at home.

各种从句的关键之点

1、定语从句

①引导词的选择一定要“两看”：一看先行词是什么（人、物、时间、地点、原因等），二看先行词在从句中的句子成分。

即使同样的先行词，如果从句句子结构不同引导词就可能不同。引导词的误用多数原因在于没有看先行词在从句中的句子成分。

提示：判断先行词在从句中的句子成分的方法是从句结构――从句缺什么成分，先行词就作什么成分，从句结构完整（什么也不缺）先行词就作状语。

I still remember the days when I lived in the countryside.

lived是不及物动词，从句结构完整，先行词指时间作从句状语用when引导

I still remember the days which I spent in the countryside.

spent是及物动词，缺宾语，先行词虽指时间但作宾语只能用which引导

②牢记只能用that的六种情况和只能用which的两种情况（非限定定语从句和在介词后）。

③把握which、as以整句为先行词的两点用法区别：一是位置上as从句可在句首、句中、句末都可以，如同状语一样，which从句只能置于句末；二是意义上，as有“正如”之意，which没有（仅指代前面的事情）。

As we had expected, they won the game. “正如”我们的预料，他们赢了

= They, as we had expected, won the game.

= They won the game, as we had expected.

They won the game, which we hadn’t expected. 我们没有料到他们赢了

④牢记what和how不能引导定语从句，只能引导名词性从句。

That’s all that I want to say.

在代词all后I want to say作定语从句，用that引导

That’s what I want to say.

在联系动词is后I want to say作表语从句，用what引导

This is the way in which/that he worked out the problem. 定语从句不能用how引导

This is how he worked out the problem. 表语从句可以用how引导

⑤介词﹢引导词引导定语从句时，其中的介词有没有以及用哪个介词都是由先行词与从句中的某个词（主要是谓语动词或名词或形容词等）的词语搭配关系而定的。

I like the person whom the teacher mentioned.
