[讨论]OG251 NOW WITH

richard_zhang

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（A）

(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.

解释中对D和E now with 的解释是什么意思啊?

rhod

D, E里的with短语, 容易被认为和with extinction并列平行.

A选项的its numbers是指带gyrfalcon，也可以指代an Arctic bird，并且也不存在任何逻辑问题，不是存在歧义了吗？？？？

its 指代gyrfalcon, an Arctic bird 只是gyrfalcon同位语(你也可以把它看做是插入语).

为什么it只能指代主语，不能指代同位语呢？代词指代中有这样的规则吗？

我在大全上找到了一个题，大家看看

According to Interstudy, a nonprofit organization that studies health maintenance organizations (HMO’s), they estimate that, in comparison to last year, when only 36 percent of the nation’s 607 HMO’s was profitable, this year 73 percent will be.

(A) they estimate that, in comparison to last year, when only 36 percent of the nation’s 607 HMO’s was profitable, this year 73 percent will be

(B) compared to only 36 percent of the nation’s 607 HMO’s being profitable last year, they estimate 73 percent would be this year

(C) only 36 percent of the nation’s 607 HMO’s were profitable last year; it estimates that this year 73 percent will be

(D) it estimates 73 percent of the nation’s 607 HMO’s would be profitable this year; last year that was only 36 percent

(E) only 36 percent of the nation’s 607 HMO’s last year were profitable, whereas they estimate it this year to be 73 percent

这道题正确答案是C,IT就是指代的同位语a nonprofit organization

我认为,这里it是指代Interstudy, 而不是 a nonprofit organization.

giantbaby

仔细分析了下句意，it确实是指代Interstudy,看来在“n.+同位语;it”这种情况下ets认为指代n.是没有歧义的！

谢谢潜龙勿用！

C选项中的it是形式主语吧，指代后面的从句
