有劳各位xdjm,OG 72题
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.fficeffice" />
(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
OG上解释的D是什么意思: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. 并且如果C是正确的,句子的谓语是什么?
