* Such作形容词，意思是"如此的""这样的"，修饰各种名词。

Such这样的。如It is such bad weather.天气如此恶劣。

Such常和as搭配，表示一种类别。如We enjoy such a voice as hers.我们喜欢象她那样的嗓子。

Such常和表示结果的that从句搭配，表示"如此....以至于..."如

It was such a hot day that we all had to stay at home.

Such...that...和so...that...都可用来引出一个结果状语从句。由于such是形容词，所以that从句前有一个受such修饰的名词；而so 是副词，用以修饰形容词或副词，因此that从句前一般不出现名词。如

They are such kind-hearted teachers that people in the village all respect them.

The exam was so difficult that many students failed to pass it.

such+形容词+不可数名词或复数名词

c) 如果被修饰的不可数名词被much, little, 或复数名词被many, few等表示量的形容词修饰时，用so，不用such.

d) 当little表示"年纪小的"时，可用such+little+名词

There were such little children that they couldn't clean the room.
