帮我分析这样的英语句型
A wealthy matron is so proud of a valuable antique vase that she decides to have her bedroom painted the same color as the vase.这句我知道是什么意思,但that是什么意思,如何理解这样的句型,什么时候可以用that引出从句?用that与直接用and的区别在哪里?

答案

“so...that...”句型的意思是“如此/这么……以致于……”,常引导结果状语从句
and是并列词,连接并列句
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：
1.he is so young that she can't look after herself.
2.The boy ran so fast that I couldn't catch him.
3.He was so angry that he couldn't say a word.
