The word or phrase that begins this sentence should establish the contrast between the size of the United States population and the activities of its citizens. Choices D and E are the only ones that establish the contrast, and only E, the best choice, expresses meaning accurately with the phrase Although accounting for. With in choice A and Despite having in choice D confusingly suggest that United States citizens somehow possess, rather than constitute, 5 percent of the world's population. Choices B and C lose the contrast between the opening phrase and the main clause, and As is unidiomatic in B. 不明白OG得这句解释,AS固然没有表达这种转折对比,但as 表作为讲,也不是不通阿(当然撇开contrast不谈) 作为世界上5%的人口,美国人。。。 |
