More than thirty years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can “jump,” as pearls moving mysteriously from one necklace to another.
(A) as pearls moving mysteriously from one necklace to another
(B) like pearls moving mysteriously from one necklace to another
(C) as pearls do that move mysteriously from one necklace to others
(D) like pearls do that move mysteriously from one necklace to others(B)
(E) as do pearls that move mysteriously from one necklace to some other one Choice B, the best answer, correctly and idiomatically uses the preposition like to introduce a comparison that is expressed, in a prepositional phrase. In A, as is used unidiomatically; in comparison, as is properly employed as a conjunction introducing a subordinate clause. Choices C, D, and E are all faulty because the verb do suggests that the migrating pearls are presented as a real phenomenon, not as a figurative illustration. 请教这句话是否表示虚拟的意思?为什么这里不可以用as ...do....的形式,好像在大全只有这题是like sth doing的用法。Also, in D, like is used ungrammatically to introduce a subordinate clause (pearls do...); and in E, the phrase some other one, substituted for another, is awkward and wordy. |
