OG 72

The number of undergraduate degrees in engineering awarded by colleges and universities in the United
States increased by more than twice from 1978 to 1985.
(A) increased by more than twice
(B) increased more than two times
(C) more than doubled
(D) was more than doubled
(E) had more than doubled

B和D到底意思有什么不同?

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.

那句话到底是什么意思??

times has more than one meaning.  1. occasions  2. multiply of number

so, OG explains that B distorts the sentence's meaning, stating that the number of engineering degrees conferred increased on more than two distinct occasions

we will know such multi-meaning words as rare and including from the explanation of oG.

真不好意,还是不懂?/

A)说twice前不能有by，那么去掉by是否是正确呢？这是问题一。

问题二：. B distorts the sentence's meaning, stating that the number of engineering degrees conferred increased on more than two distinct occasions. ---two distinct occasions是什么意思？

问题三：(C) more than doubled---读起来很拗口，double前可以有比较副词修饰的么？

这个题目我选了B，看了答案应该是C。请大家帮忙揭开偶的疑团。。。。

个人感觉：在ＧＭＡＴ答案中，double即是动词，又简洁，因此如果有double还有其他times项，那么times 项可首先排除，选择范围可立即缩小

我觉得可以。虽然不如c简洁，但也不错呀。

谁给确定一下。
