GRACE ：小教室现在好象就你在哦！帮我讲一下OG 的Q205吧 1我想不明白ETS 说的D和E 的ALTHOUGH从句的错误-Choice E uses the correct verb form, is, but it incorrectly introduces a dependent adverbial although clause into a prepositional phrase (with crests...). Choice D also makes this error. Such dependent clauses can only occur in the predicates of full clauses. 2：菜鸟手册说的我也不太明白：介词短语中用了一个从句错，although这样的从句只能用在有主句的句子中-必须有主句谓语动词。 但正确答案中也有个ALTHOUGH从句在WITH 短语中啊！ 3：菜鸟中的：sth that remains plus a.这种形式的定语从句是不能简化的;系动词的话就可以简化，注意这个简洁的陷阱。 是什么意思啊？？ 谢谢了！连菜鸟的都不明白！我该做一个菜鸟的菜鸟的小鸟篇了！ 205. The peaks of a mountain range, acting like rocks in a streambed, produce ripples（波纹） 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 |
