OG-95:The peaks of a mountain range, acting like rocks ina streamed,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 know as "standing waves"
(C).crests and troughs that remain stationary although the air that forms them is moving rapidly,is
(E).stationary crests and troughs although they are formed by rapidly moving air,is
although的存在是为了表达转折的含义,从句意上看是stationary和moving rapidly的转折对比 先看正确选项,连接的是that remain stationary 和the air is moving rapidly,结构、含义上都非常对称。 再看正确选项E里面although连接的却是crests and troughs和they are formed by rapidly moving air,可以发现crests and troughts与它们怎么形成的无法形成一个"转折"。能形成转折的是crests and troughts的stationary和air的moving rapidly.
