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
(E) stationary crests and troughs although they are formed by rapidly moving air, is
答案是C
千行说E的被动不是很合适 有木有能翻译一下的TAT C 和E
另外说with结构中although 用法不好这里although的用法是不符合语法结构的(manhattan):语法层面:
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.
意思层面:
We want to contrast "stationary" with "rapidly moving air", (e) doesn't present that contrast clearly.
一开始做也选了E,觉得C awkward
但看解释的话还是觉得C好 although 应该是 separate a CLAUSE (with a verb) from another CLAUSE (with a verb)非常对啊觉得,所以although 引导的句子应该属于creasts and throughs 的定从里面的
意思层面也有道理啊,要强调stationary and rapidly 的话就不能把它们单单作前置的形容词,用主系表结构作表语还是很合适的~
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."
拿掉修饰成分 其中主句是the resulting flow pattern are known as "standing waves." OK
两个逗号之间 是 with独立主格结构作伴随 这里属于with + 名词 类型的
名词是crests and troughs,而它有跟着一个定语从句that。。。。。先行词在该从句中作主语
代入还原之后是 crests and troughs remain stationary although the air that forms them is moving rapidly
这个句子OK,crests and troughs remain stationary是主句,although the air that forms them is moving rapidly是从句,although是连词,表前后意思相反,翻译是
crests and troughs是静止不动的,尽管形成它们的air运动的很快~
