so that引导结果状语从句和目的状语从句有什么区别？

Answer 1

So that既可以引导目的状语从句，又可以引导结果状语从句，区别是：1）so that引导的目的状语从句中常会有情态动词can,could,may,might,will,would等，而so that引导的结果状语从句中一般没有情态动词；2）So that引导的目的状语从句之前不用逗号，而so that引导的结果状语从句与主句之间往往有逗号相隔开（即略作停顿）。请比较： He worked hard at his lessons so that he could gain high grades in the exams.他努力学习功课，争取考试能获得好成绩。 He worked hard at his lessons, so that he gained high grades in the exams.他努力学习，结果考试获得了好成绩。
