So that 和such that有什么区别？就是后面加的词性有什么区别？
区别有以下几点：
（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。 后面不加，一般在前面加，详细分析如下：so that引导目的状语从句时，表示“以便；为了”，从句中常使用can /could /may /might /will /would /should等情态动词或助动词；引导结果状语从句时，从句中一般不用can和may等词，在so that前可以用逗号，意思是“因此，所以，以致”。如：
He got up very early so that he could catch the train．他起得很早以便能赶上火车。（目的状语从句）
He raised his voice，so that everyone heard him．他提高了声音，结果大家都听见了。（结果状语从句）
（3）so．．．that意为“如此……以致”，只能引导结果状语从句，意为“如此……以致于”，其中so后面跟形容词、副词或由few，little，a little，many，much修饰的名词。例如：
He ran so quickly that I couldn't catch up with him．他跑得太快，我赶不上他。
The box costs so little that I can afford it.这个箱子很便宜，我买得起。
so…that与such…that
so…that用于以下四个句型：
so+形容词/副词+that…
so+形容词+a/an+单数可数名词+that…
so+ many(多) / few(少) +复数可数名词+that…
so+ much(多) /little(少) +不可数名词+that…
This teacher is so kind that we all like him. 这个老师非常和谒，我们都喜欢他。
He ran so quickly that we all couldn’t catch up with him. 他跑得很快，我们都追不上他。 This is so interesting a book that we all enjoy reading it. 这本书非常有趣，我们都喜欢看。 He has so many books that I can’t count them. 他有很多书，我数也数不清。
There was so much food that we couldn’t eat it all. 食物太多了，我们吃不完。
I have so little money that I cannot afford a car. 我的钱太少，买不起车。
注：若little表示“小”时，要用such。如：
He is such a little boy that he can’t lift the box. 他是这么小的小小孩，提不到那个箱子。
2. such…that…用于以下三个句型：
such+ a/an+形容词+单数可数名词+that…
such+形容词+复数可数名词+that…
such+形容词+不可数名词+that…
This is such an interesting book that we all enjoy reading it. 这本书非常有趣，我们都喜欢看。
They are such interesting books that we all enjoy reading them. 这些书很有趣，我们都喜欢看。
