(1)“so+adj./adv.+that” ， “so+adj.(+a/an)+n.+that”；
(2)“such(+a/an)(+adj.)+n.+that” 。

如果结果状语从句的主语与主句的主语相同，可用so(adj/adv)as to取代该结果状语从句，注意体会以下例句：

天气恶劣，以致难以拍出来好照片。
He was so kind as to phone for a taxi for the patient 。

How could you be so stupid as to believe him?
你怎么这么笨，竟相信了他的话？
在结果状语从句主从句主语一致的情况下，可省去从句主语，从句谓语变非谓语。这时，前面的so...就要换一个形式来陈述。so是中性程度副词，如果从句是肯定句，那么so就要换为enough 。如果从句是否定句，那么so就要换成too 。要注意的是：enough只能在所修饰词的后面。例：
He is so old that he can go to school alone 。省略式为：He is old enough to go to school alone 。
