英语怎样判断so后面的从句是用that还是as阿?

判断的标准应是根据句子的意思.
so...(that) + 从句 是状语从句,翻译成 如此……以致于…
例如：You are walking so fast that I cannot catch up with you.
so...(as)=as...as 也可跟状语,翻译成 像.一样
例如：You are walking so (as) fast as I am.
Your brother is so (as) tall as you.
这句 you are so clever as everyone likes 是什麽意思呢?as 改成that 更通一些.另外,即使这样,其中的as.也应是状语.
