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.
主要想问A/B的区别, 解释里面说B用more, 表示鸟儿有更多种群, 而非更多鸟, 而实际上原句的意思是鸟儿的数量增多,而非种群增多, 我想问more 表示种群增多,而greater表示数量增多呢?
