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.
如果名词是可数名词的单数形式,such和so的位置不同：
such+a/an+形容词+单数名词
so+形容词+a/an+单数名词
如果名词是不可数名词或名词复数,只可用such,不能用so.:
such+形容词+不可数名词或复数名词
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.
当little表示“年纪小的”时,可用such+little+名词
