力刻行动 搞定英语
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：
-
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。 -
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？
- 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。
