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？

偶也不懂,哪个nn解释一下啊

这个,怎么没有人解释下~~~

C的谓语是double，double可以作动词也可以作形容词；

double本身就可以是形容词

more than连在一起可以作为一个副词，当然可以修饰动词，注意，这里的more than不是分开的，是连在一起的。D的DOUBLE是一不及物V.所以沒有被動
