从句是指用于复合句中担当某个句子成分的主谓结构。虽说从句自身的句子结构是完整的， 但是它不能视为独立的句子，因为它离开了主语就无法独立、完整地表达意思。

按其所能表达的意义而言,它相当于一个词或是一个词组.
如：

1. Because they talk at home while the television is on , many people think they can talk at movies as well .
   （状语从句）许多人在家里是边看电视边谈话，所以他们认为在电影院也可以如此。

2. Whether he comes or not doesn't make any difference to me .
   （主语从句） 他来与不来对我都一样。

3)There is disagreement among economists about what money is and how money is measured.
（宾语从句）什么是货币以及怎样计量货币经济学家之间存有分歧。

4） China is not what it used to be .
（表语从句）中国不是它过去的样子了。

5） Is there any proof that the food of plant differs from that of animals ?
（同位语从句）有没有什么证据说明植物性食品不同于动物性食品？

6. Taxes consist of money that people pay to support their government .

（定语从句） 税款是人们支持政府而交的钱。

如果将上面的复合句中所有的从句都独立出来，那将是这样的：

1） Because they talk at home while the
television is on.

2） Whether he comes or not .

3） What money is and how money is
measured.
4） What it used to be .

5That the food of plant differs from that of animals

6） That people pay to support their government .

我们很容易看出，上面的所有这些句子既不是陈述句、疑问句，也不是祁使句，更不是感叹句。

也就是说，它们不是独立的句子；也只有在附属于主句后才能获得意义。
