标题: OG72:

OG72:

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

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.

解释里划线的这句话是什么意思啊?

D's passive verb was ... doubled suggests without warrant that some unnamed agent increased the number of engineering degrees.

意思就是D里用was..doubled的被动语态，就暗示着必须有一个句子中没有提及的agent使得engineering degree的数量增加，这个是没有正当理由的(without warrant)..

b为什么错呀，没看明白，nn没给解释一下

b 说的是two times 是指“两次“，而twice 是指“两倍”（虽然twice也有两次的意思但是这里是指倍数），改变了句子的意思，所以错！
