英语从句（英语兔学习笔记）

主语+谓语+宾语
主语+系动词+表语

1.名词从句

主语从句

The fact is obvious.

the fact是主语，如果我们将主语换成一个从句，那么这个句子就变成主语从句.

主语从句是以引导词开头的。

That the rabbit ate a carrot is obvious.
Whether the rabbit ate a carrot is obvious.
where the rabbit ate a carrot is obvious.

当主语从句太长的时候，比如下面的句子。我们通常将这个句子转化为形式主语引导的句子。

That the hungry rabbit had already eaten a carrot for dinner this evening is obvious.

It is obvious that the hungry rabbit had already eaten a carrot for dinner this evening.

宾语从句

I saw that the rabbit ate a carrot.
I saw whether the rabbit ate a carrot.
I saw who the rabbit ate a carrot.

表语从句

The problem is that the rabbit is hungry.
The reason is that there is no more rabbit.

同位语从句

My teacher, papa rebbit,likes rabbits.
The fact that the rabbit ate a carrot did not suprised me.
I have no idea who ate a carrot.

宾语补语从句

you can call me papa rabbit.

me 是宾语，papa rabbit 是宾语补足语。如果我们将宾语补足语换成从句，就变成了宾语补足从句。

you can call me what you like.

2.形容词从句(定语从句，关系从句）

修饰名词，翻译为…的

由先行词，关系词，定语组成。

先行词：要修饰的词

关系词：that,who,which,whose等，当that与which可以互换时，我们可以判断，先行词是否唯一的，如果是唯一的，用that，如果不是唯一的，用which。

关系副词：关系词没有词性。

关系代词：关系词指代先行词。

定语：充当形容词的成分，去修饰先行词。

兔子在吃一根胡萝卜

The rabbit is eating a carrot.

兔子在吃一根我买来的胡萝卜

The rabbit is eating a carrot that I bought.
