1、so可用来修饰形容词和副词,such修饰名词.

He is such an old man.

He is so old (a man).

2、对比用法:so+形容词+冠词+名词 so important an event

such+冠词+形容词+名词 such an important event

通常是区别so ...that,such...that用法.

3、名词前有表示“多、少”意思的manymuchfewlittle时,只能用so,不能用such.

There are so many flowers in our school garden.

Ihave so little money that I can't lend you any.

另:当little表示“小”时,只能用such 不能用so 修饰
