With only 5 percent of the world's population,United States citizens consume 28 percent of its nonrenewable resources, drive more than one-third 0f its automobiles, and use 21 times more water per capita than Europeans do.

答案A。 对于C和D答案OG给的解释是 C Although typically introduces a subordinate clause, which has a subject and a verb, but here there is no subject and sighted is not a complete verb. D Although usually introduces a subordinate clause, but there is no subject of the clause and having been sighted is not a complete verb phrase.

不对啊..........句意明显就不是这个意思。
反正关于although这个问题只在论坛上看到过一个模棱两可的解释T-T:
C- Although typically introduces a subordinate clause
D- Although usually introduces a subordinate clause
其实OG没有否认although后存在句子省略的情况,但解释太略,很多话没说清。我一般重点看解释考点那段话。
牛津高阶:

1 Although and (even) though can be used at the beginning of a sentence or a clause with a verb. *although和(even) though均可用於句首或从句之首, 与动词连用.

2 However can be used to give a similar meaning, but must begin a new sentence *however也可用以表达相同的意思, 但必须用於另起一句的句首: We all tried our best. However, we lost the game. 我们都已尽了最大的力量. 但我们还是输了.
3 Though and however can come at the end of a sentence *though和however可用於句尾: We all tried our best. We lost the game, though/however. 我们都已尽了最大的力量. 不过我们还是输了.

难道是第4条的意思>_>........
●although省略的情况:although放于句首,主语与主句一致,后面是系动词be+形容词,则主语和系动词可以省略。如:Although young, he plays basketball well.
但比如这道题Although accounting for only 5 percent of the world's population, United States citizens consume 28 percent of its nonrenewable resources, drive more than one-third of its automobiles, and use 21 times more water per capita than Europeans do.
