173/DQ549.  Once an apolitical confrontation of the world’s best athletes, the Summer Olympics have been increasingly politicized in recent years as the superpowers have denied many of the best athletes’ access to competition.

(A) been increasingly politicized

(B) been increasing politicization逻辑搭配不对

(C) been of increasing politicization逻辑搭配不对

(D) politicized, increasingly,（A）要用被动

(E) increased politicization逻辑搭配不对/要用被动

答案没有问题

  Once an apolitical confrontation of the world’s best athletes这里的once 是什么意思 作什么用啊

在朗文中作连词/介词 用在这里都不对

谢谢

副词，一次，修饰apolitical

世界上最优秀运动员一次不关心政治的面对面。

Once: in the past, at a time that is not stated 这里的意思是一度，曾经。

奥运会曾经是世界上最优秀运动员之间非政治的对抗，但是最近几年被迅速的政治化了blah blah...

谢谢rhod/leeon  明白了

看来我的阅读还不行啊
