65 有关so做替代词的问题

老师,您们好!

We must find ways to protect our environment.If we fail to do so,we'll live to regret it.

=We must find ways to protect our environment.If we fail to find ways to protect our environment

对于上述的so做替代词用法,我有些不结。

第一,do sodo是实义动词还是替代词的do

第二,这个例句说明了so是替代find ways to protect our environment。但是我如果将这一替代的部分放在do后面又有点说不通,因为之前看过I hope so这类so所替代的成分都是可以直接归回还原的。但是在do+so这种情况,如果要还原so的替代部分,却是要把do so这整体替换为find ways to protect our environment

请教老师,如何理解这一现象?

do so 就是替代前面的动词和宾语等,目的是避免重复,即使用中文也好理解,如:如果你这样做,就违法了。“这样做”(do so),肯定是指前面提到的事。

你说:这个例句说明了so是替代find ways to protect our environment。但是我如果将这一替代的部分放在do后面又有点说不通

你的理解不对。do so 是一个整体,=find ways to protect our environment.  你既然用了do so,就不允许你那样还原或增补,是错误的。

do so hope so,形式相似,但不完全一样。《牛津英语用法指南》因此把它们分开来解释,请看该书对do so hope so 的解释,非常清楚,也回答了你的问题:

ope so. so 是代替that 从句里重复的词。
