【简明语法】7.7 不定式作状语

（单词翻译:单击）

1）目的状语　
To… only to (仅仅为了),　in order¹ to,　so as² to,　so(such)… as to… (如此……以便……)
　　He ran³ so fast as to catch the first bus.　他飞快地跑以便赶上第一班车。
　　I come here only to say good-bye to you.　我来仅仅是向你告别。

2）作结果状语，表事先没有预料到的，要放在句子后面。

　　He searched⁵ the room only to find nothing.

典型例题
　The chair looks rather⁶ hard, but in fact⁷ it is very comfortable⁸ to ___.　
　A. sit　 B. sit on　 C. be seat⁹　 D. be sat¹⁰ on
答案：B.　如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。
