OG SC 251 旧题新问

米米时代007

OG251. 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.
看了解释DE也不明白为什么with后不能修饰主语The gyfalcon--the numbers are possessed by "The gyrfalcon", aren't they?

d/e都是 absolute phrase:
..., with + noun + noun modifier
我记得Ron说过，这里逗号后面、with前面，不能加任何东西（这题加了now），必须with跟在逗号后面。

这话不对吧.....numbers怎么会是复数呢（我看5个选项都是，只好忽略....），应该是 its number is ...

btw:哪里的题目？OG没有251，只到140

听说是OG10里的吧，是08prep SC1解释里的，是the numbers表示数量这个整体，the number就表示有多少个数，我记得manhattan里也有the numbers这个用法的。关于独立主格，硬套语法点不知道对不对，但就其解释来讲我不能接受。这道题在07prep里也有，具体忘了哪个了，120题以后的一道。

那你看这个吧

这道题的讨论，有3页

the number of
见Manhattan p.41

发现Stacey (Manhattan instructor)也说这题numbers不对

the number表示数字    
The number of students is 50
The numbers of the students in those three classes are 50, 51, 52, respectively.  

第一个例子只有一个数字：50
第二个例子有3个数字，分别是3个班的人数，所以才是复数。

一般我们说"the number of sth."都是单数，因为数字只有一个，所以Stacey会说不存在"the numbers of"。但我上面举的第二个例子太特殊，举了3个数字，所以是numbers。

这题，但说its number，必然是"its number"而不是"its numbers"，因为number只有一个，例如这个鸟的数量是1000只，那么这个number就是指1000这一个数。

除非这题说，"its numbers in different regions"，这样对于每一个region都存在一个number，有多个number，才能用numbers

另一个问题是with后那一串为什么不能修饰the g..?

babybearmm

那个链接里面,ron说的意思是: ", now with ..." 那个now没有修饰对象
我们知道now是副词，需要修饰动词，假如说把now去掉，逗号后面的成分是 with+noun+noun modifier
根本不存在动词，所以now在逗号后面没有修饰对象。

另一个问题是with后那一串为什么不能修饰the g..?
