和“that‖连用时，意思为”如此…以至于…‖，但句型结构不同。1. so + 形容词/副词+ that + 从句，如：
This story is so interesting that I want to read it again. He spoke so quickly that I couldn?t follow him. 2. so+形容词+(a/an)+单数名词
She is so lovely a girl that everyone loves her. 3. so +many（few）+复数n. +that…
so +much（little）+不可数n. +that…如：
There were so many people that we could hardly move on.4、such+a/an+形容词+单数可数名词+that+从句，如：She is such a lovely girl that everyone loves her.
It is such an interesting story that I want to read it again. 5. such+复数可数名词/不可数名词+that+从句，如：
They are such delicious cakes that I want to eat another two. It is such sweet milk that we all want to drink it.
so 和such后跟单数可数名词时，可以换用，同样“so…that…‖与“such…that…‖也可以进行同义句改写。
如：This book is so interesting that I have read it three times. =This is such an interesting book that I have read it three times.
It was so hot a day that nobody wanted to do anything. =It was such a hot day that nobody wanted to do anything.3. so与that可以直接构成词组“so that‖，引导目的和结果状语从句，表示“以便、以致”的意思。如：
He worked hard so that he could pass the exams. 为了能通过考试，他学习很认真。（但such没有这种用法）
