If current trends continue, by the year 2010 carbon emissions in the United States will soar to a level more than one-third higher than were those in 1990, according to official projections.
(A) will soar to a level more than one-third higher than were those
(B) will soar to a level more than one-third higher than that
(C) would soar to a level more than one-third higher than it was
(D) would soar to a level more than one-third higher than those
(E) would soar to a level more than one-third higher than they were
A.复数those不能指代单数level,因此只能强制指代前句的复数主语emissions,那么,句子变成将level与emissions相比较,比较对象不对等
上述是官方解释,那么请问,A是否后面改为单数(than was it),C用了will(than it was),就都成立呀?
