Question

12．在整个冬季由于天冷他停止了锻炼，以至于他的体重增加了3公斤．
During the whole winter，hestopped doing exercise so that he put on weight by 3kilograms because of the cold weather．

Answer 1

分析 stopped doing exercise so that he put on weight．

解答 答案：stopped doing exercise so that he put on weight．这里是说过去的事情用一般过去时，表示停止做某事用stop doing sth，stop的过去式是stopped，故stopped doing exercise，以至于用so that引导的结果状语从句，体重增加用put on weight，put过去式还是put，故答案是stopped doing exercise so that he put on weight．

点评 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；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.\x0dHe 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．
