72. The
number of undergraduate degrees in engineering awarded by colleges and
universities in the
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.
我比较笨，为什么还是看不太明白og中解释，这more than twice, more than two times more than dobuled到底有什么区别呢？多谢牛牛指点：）
不是 more than和这几个词搭配的错，是其他错误。
by twice, twice是副词，无法做介词by的宾语
two times,有两次的歧义，two occasions.
more than doubled, doubled是动词。正确。
