不分开的话是这样： so... that...句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj. / adv. + that从句。例如： he is so young that she can't look after herself.
在“such... that...”句型中，such修饰名词，意思也是“如此……以致于……”但当名词前有many、much、(a) few、(a) little等词修饰时，句子中要用“so...that...”而不能用“such...that...”。例如： He has so much money that he can buy what he wanted.
so与that也可连起来写，即变成：... so that ...(以便 / 为了……)，引导目的状语从句。例如：
1. I got up early so that I could catch the early bus.
2. Please open the window so that we can breathe fresh air.
就这些，有什么问题还可以问我！
追问分开写是什么从句？
追答同学，你好！
分开写不是什么从句他是一种固定句型：主语+谓语+so+adj. / adv. + that，表示××怎么样以至于××，that 后引导一个结果状语从句。
