神剑魔刀 国语

Bob took down my telephone number so as（in order）not to forget it.

2）作结果状语
不定式作结果状语大多数时候表示出人意料的、令人不快的或让人失望的结果，常在不定式前加only。如：
We came home after our holiday only to find our house clean and tidy.
我们度假回来却发现屋子干干净净。
They went hurriedly into the classroom only to find that the class had begun.
