这道题答案不是C吗？ increased 和more then doubled重复肯定错。排除A,B. since then明显是现在完成时的时间状语，我认为D,E不对。 E中since then把its circulation 和its advertising分开 显然不好。 讨论。 作者: ecsniffer 时间: 2004-1-5 14:41
我一看到这题错选了D。后来分析是对since作adv.的用法不甚了解造成的。 从m-v中摘了一段： since adv. 1 : from a definite past time until now 2 : before the present time : AGO 3 : after a time in the past : SUBSEQUENTLY 这里c选项中since是第3种用法，since用于现在完成时态。
