such..that和so..that的区别和用法
such…that…与so…that…都可以用来引导结果状语从句,意为“如此……以致……”.
（1）such是形容词,它所修饰的名词可以是可数名词,也可以是不可数名词；名词前面可以带形容词,也可以不带.如果其后是单数可数名词,前面需加不定冠词a或an.因此,such…that…的句型结构可分为以下三种：
①such+a（n）（+adj.）+单数可数名词+that从句.如：
She is such a good teacher that all of us love and respect her.她是一位很好的老师,我们都敬爱她.
Table tennis is such an interesting game that people all over the world play it.乒乓球是一项很有趣的运动,以致全世界的人都参加这项运动.
②such（+adj.）+复数可数名词+that从句.如：
They are such interesting books that I want to read them once more.这些书非常有趣,我想再读一遍.
③such（adj.）+不可数名词+that从句.如：
It was such bad weather that I had to stay at home.天气太坏,以致我不得不呆在家里.
（2）so是副词,与形容词或副词连用,其结构是：so+adj.（adv.）+that从句.如：
He ran so fast that I couldn’t catch up with him.他跑得那么快,我赶不上他.
I am so sleepy that I can hardly keep my eyes open.我太瞌睡了,眼睛几乎睁不开了.
注意：①当名词前面有many,much,few,little等表示数量多少的限定词时,应该用so,而不能用such.如：、
There were so many people in the street watching the fire that firefighters could not get close to the building.街上围观大火的人太多了,消防队员无法靠近大楼.
②当单数名词前有形容词时,既可用so,也可用such,但不定冠词的位置却有所不同.如：
This is such an important meeting that you should attend it.（=This is so important a meeting that you should attend it.）这是一次很重要的会议,你一定要参加.
