让我们先来看一下本单元的几个句子:
In order to survive, Chuck develops a friendship with an unusual friend-a volleyball he calls Wilson. 为了求生,查克交了一个不同寻常的朋友-- 一个被他叫作威尔逊的排球。
... who is always so busy that he has little time for his friends. 他总是很忙,以至于几乎没有时间交朋友。
这两句中,in order to +动词原形引导目的状语。so as to +动词原形,to+动词原形都可以引导目的状语。
