1．动词不定式作状语
(1)动词不定式作状语表示目的。有时为了强调目的状语，可以在不定式之前加上in order或so as，即构成in order to do sth.和so as to do sth.结构。in order to do sth.可以位于句首，so as to do sth.则不能。
(2)动词不定式作状语表示结果。一是常用于too ...to ..., enough to do结构中表示自然而然的结果；二是表示意料之外的结果，其前面经常加only，位于句末。
(3)动词不定式作状语表示原因。经常位于表示感情的形容词如happy, excited, pleased, surprised, curious等后面。
