句子里的that 如何用?
I'm sorry,my knowledge is so poor *that I can't help you right now.

翻译成以至于,that引导定于从句如果我这样造句可以吗?

He's broken his arm that he cannot go for work.that前加上so,so that是完整的以至于是不是 so...(谓语)...that ...(类似后果)... 这样?

He's so proud that everyone dislikes him

这个句子可以吗?so 后边一般加的是形容词或副词,谓语加在so前边儿
