同样疑惑的一个问题,OG中有这样的用法:虽然选项是可以选出,但是numbers的用法不是特别明白。顶这个帖子,请教大家,对number/numbers是否有新说法? 48. The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths-- 2,500 to 3,000 feet down. (A) on account of living (B) on account of their living (C) because it lives (D) because of living (E) being they live As used in choices A, B, and D, the phrases on account of and because of are unidiomatic; because, which appears in C and E, is preferable here since because can introduce a complete subordinate clause explaining the reason why the golden crab has not been fished extensively. B and E also produce agreement errors by using the plural pronouns their and they to refer to the singular noun crab. Choice D, like A, fails to provide a noun or pronoun to perform the action of living, but even with its the phrases would be more awkward and less clear than it lives. C, which uses because and it as the singular subject of a clause, is the best choice 251. The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. . (A) extinction; its numbers are now five times greater than (B) extinction; its numbers are now five times more than (C) extinction, their numbers now fivefold what they were (D) extinction, now with fivefold the numbers they had (E) extinction, now with numbers five times greater than A, the best choice, uses a singular pronoun, its, to refer to the singular antecedent The gyrfalcon, and it properly uses the construction its numbers are now ... greater than. In B, the construction its numbers are ... more is not idiomatic: there are more birds, but not more numbers. Choices C and D use a plural pronoun, their or they, to refer to a grammatically singular antecedent, The gyrfalcon. Choices D and E wrongly use a phrase introduced by now with to modify The gyrfalcon. In both choices, the phrase confusingly seems to parallel with extinction; a new clause with a present tense verb is needed to state what the gyrfalcon's numbers are now
