请问在 TPO 32L 第三个 Lecture 有题是问
what does the professor imply when he mentions an Olympic whitewater
kayaking competition?
请问我听原句相关的是这两句
Alough I should mention that by 1966, the water in one of the rivers flowing
through the basin was clean enough that it was the site of the Olympic
whitewater kayaking competition.
And that river is still used now for recreation
请问这样怎么推论到正确答案
That a successful reclamation of the Copper Basin may be possible
请版上练习过的高手解惑了
谢谢！
