考点:
1.伴随状语:doing引导伴随状语或者目的状语
2.前后句关系平行一致
3.不可数名词,抽象名词不可用many形容
4.AlienX: "of XXX(年份)"在OG/Prep上常出现, 所以of previous year没问题
5.注意这个题的含义 (http://forum.Topway.com/GMAT_SC/thread-376052-1-1.html ):
不是说:今年的人数(total number)在增长以后,是去年增长人数(increase of the previous year)的两倍。
而是说:今年的增长(increase)是去年(increase)的两倍。
aeoluseros: 这里的double是"make twice as great"的意思,也就是使increase/growth两倍. (Explanation from LDOCE: “To become twice as big or twice as much or to make something twice as big or twice as much”)
AlienX: 我觉得doubling the increase of the previous year=使1990年的increase在the increase of(更多外语考试资讯尽在http://waiyu.kaoshibaike.com) the previous year的基础上倍增.
来看另外一个非常像的句子:
P1#242: Retail sales rose 8/10 of 1 percent in August, intensifying expectations that personal spending in the July-September quarter would more than double the 1.4 percent growth rate in personal spending for the previous quarter.
同理, personal spending in the July-September quarter would more than double the 1.4 percent growth rate in personal spending for the previous quarter=personal spending in the July-September quarter的growth rate在the 1.4 percent growth rate in personal spending for the previous quarter的基础上倍增.
6.Double和twice都可以直接作为predeterminer(如C,D,E选项),而doubling中的double是作为及物动词(如A,B选项).
