such与so的区别与用法
such与so的意思都是“如此,这样”.但两者用法根本不同,与what和how引导的感叹句相类似.
1、such后面主要是修饰名词.即：such＋a/an＋adj.＋n.或a/an＋such＋adj.＋n..如果名词是不可数名词或复数名词,则不可以用不定冠词a或an.如：
①He has such a beautiful bike.We all go to see it.
②It's a such fine day.We al want to go to fly a kite.
2、so后面只能跟形容词或副词.即：和so＋adj.或adv.不过,so后面也可以跟名词,但该名词必须是单数可数名词.用法为：so+形容词+a或an+单数可数名词.如：
①The tiger is so big.And the cat is so small.
②She is so lovely a girl.
3、它们后面还可以与that从句连用.即：such…that和so…that意思是“如此……以至……”.如：
①She is such a clever girl that she can make much progress in math exam.
②His brother is so young that he can't go to school.
注：当名词前的形容词为表示数目的词时,such必须换成so.如：
①There are so many people that we can't go past.
②I ate so much food that I didn't want to go any farther.
注意这一句话：Smith has made so much progress that we are all surprised ..
进步是不可数名词,因此用much（修饰不可数名词）.many修饰可数名词.
so是副词,只能修饰形容词或副词.只有so能与much连用.一般来说,so many 和so much可以成为固定的词组
PS：上面竟然有人说progress是可数名词.
