205. 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.”
(A) crests and troughs that remain stationary although the air that forms them is moving rapidly, are (B) crests and troughs that remain stationary although they are formed by rapidly moving air, are (C) crests and troughs that remain stationary although the air that forms them is moving rapidly, is (D) stationary crests and troughs although the air that forms them is moving rapidly, are(C) (E) stationary crests and troughs although they are formed by rapidly moving air, is 首先, 文法中, Although所引導的Adv-CL是用來修飾Main-CL的,所以我們會看到Although+S+V, S+V.的結構. ANS(D)及(E)中although的位置使得Adv-CL修飾Main-CL: the resulting flow pattern is known as "standing waves".(不能修飾分號前的句子,因為分號前後句意上比較沒有關聯). 然後如果把Adv-CL搬到Main-CL的前面,變成以下: Although the air that forms them is moving rapidly, the resulting flow pattern, with stationary crests and troughs, is known as "standing waves". 雖然Adv-CL跟Main-CL主詞不一定要一樣,但這樣句子會不會唸起來很怪呢? them是指誰? 是the resulting flow pattern還是crests and troughs,因此則造成句意awkward 所以ANS(C)用了that remain stationary讓although引導的Adv-CL有明確的修飾對象!
