2.My dad gave me the binoculars so that we can see the birds better.(教材P19)

我爸爸给了我双筒望远镜以便我们看鸟能看得更清楚一些。

【句式解读】句中so that引导的从句在句中作目的状语，作用上相当于“in order that＋从句”。

【用法总结】

(1)so that引导目的状语从句时相当于in order that＋从句，从句中常用could，might等情态动词，该结构可以改写为so as to do sth或in order to do sth。

①My father began to study computer in his sixties so that/in order that he might keep up with times.＝ My father began to study computer in his sixties so as to/in order to keep up with times.

我爸爸在六十多岁时开始学习电脑以便跟上时代。

(2)so that也可引导结果状语从句，一般不与could，might等情态动词连用。

②She hadn’t planned her time well so that she didn’t finish her work on time.

她没有计划好她的时间，因此她没有按时完成她的工作。

[巩固内化]同义句转换

→We went to the airport _________________________________ Professor Yang there.

②I study hard so that I may not fail in the exam.
