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" 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
其它三个选项都有明显错误，在这里就不列举了 答案是C 我选的是E 解释说E中的被动awkward和unclear 我的疑问是，C中的 that remain stationary跟E比应该是wordy和awkward啊。E的被动我也考虑过，虽然被动，但是E中的stationary crests and troughs 却比C用得好。很无语的是题目的解释总是习惯性的忽略正确答案中的那些瑕疵。。我认为C和E都有缺点，也都有对方所不具备的优点。不知道应该怎么做。。我做语法时经常会遇到这种情况。几个选项都有瑕疵但也都有用得好的地方，这道题就是个好例子。一旦遇到这样的题我就会纠结很久最后选择一个我认为更好的。。这样往往最后正确率不高。。不知道大家有没有遇到这种情况呢？有什么好办法吗？是我不扎实？
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.
