弱问OG72！

HoneyMilk

(A) increased by more than twice

(B) increased more than two times

(C) more than doubled

(D) was more than doubled（C）

(E) had more than doubled

原文increaseed by，不是增加了2倍、变成3倍的意思吗？

为什么选二倍多。。。

Answer to Question 72
Choice A is faulty because an adverb such as twice cannot function as an object of the preposition by. B distorts the sentence's meaning, stating that the number of engineering degrees conferred increased on more than two distinct occasions. D's passive verb was ... doubled suggests without warrant that some unnamed agent increased the number of engineering degrees. The past perfect tense in E, had... doubled, is inappropriate unless the increase in engineering degrees is specifically being viewed as having occurred further back in the past than some subsequent event. Choice C is best.

感觉这道题主要有两个考点：1， 时态；2，表“增长”的正确表达。

时态基本搞清楚了，但对后者看了答案仍有不解哦。。根据解释，是不是可以认为如果把a改成：increased by more than 200% 就是可以接受的答案了？

lz的疑问请nn解答哈，我也觉得c选项没有充分保证与题意的一致

如果其他答案有严重错误时，也可以选与原题逻辑意思不完全一致的选项，做题不能绝对化。
