The peaks of a mountain range, acting like rocks in a streambed, produce ripples in the air flowing over them; the resulting flow pattern, with crests and troughs that remain stationary although the air that forms them is moving rapidly, are known as "standing waves".

D. Stationary crests and troughs although the air that forms them is moving rapidly, are
E. Stationary crests and troughs although they are formed by rapidly moving air, is
答案选C,我当时在C,E之间徘徊很久,不是很理解为什么说E选项里although状语从句不能修饰介词短语。有没有牛牛来帮我解释一下!!谢谢大家啦!!!!
although这里的用法是不正确的,以下来自DUKE版主的千行中的摘要(借花献佛),
“incorrect use of 'although' in the subordinate clause: 'although' has to separate a CLAUSE (with a verb) from another CLAUSE (with a verb). 'Stationary crests and troughs' doesn't have a verb.”(所以我猜想这题在OG13被删除就是因为although用法不正确)
后面是我自己的见解,给LZ做个参考,而且C和E的意思也相差太远,表现如下:
1)stationary crests and thoughs 表示crests and thoughs 的本质是stationary,而Crests and troughs that remain stationary 是强调这一时刻它们保持静止,并没有说stationary是Crests and troughs 本身的性质
2)更重要的是,although里面强调的是动作is forming,翻译出来就是组成它们(Crests and troughs)的空气正在迅速移动,而D是它们形成于迅速移动的空气,C的语义和原句A差别太大,因此排除E
