求问so that的用法？

二零一八

知道so that有表目的的用法， 但是comma+so that是怎么使用的啊，因为认为so that只能表目的而差点选错了下面这道题
In many of the world’s regions, increasing pressure on water resources has resulted both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward.
Aboth from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward
Bboth from expanding development or changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern
Cfrom expanding development, changes in climate, and also from pollution, so that the future supply in some of the more arid areas is a matter of concern going forward
Dfrom expanding development, changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern
Efrom expansion of development, changes in climate, and from pollution, so that supplies in some of the more arid areas are a future concern


答案选D，但是有没有人告诉我这里的so that是什么用法呢

你是认真的吗

这里实质上不是comma+so that的用法，这里逗号的出现只是起分隔作用，from引导了三个并列的对象，用逗号分隔会使句子整个结构变得更清晰。

我们可以尝试把后两个对象删去试下，句子就变为：

In many of the world’s regions, increasing pressure on water resources has resulted from expanding development so that future supplies in some of the more arid areas are a concern

这样的结构应该就是楼主熟悉的结构了
