谢谢斑竹！！！

菜鸟弱弱地问个问题，OG不是总共只有138道题目吗？怎么会有251呀？？

AlienX

OG10有250+題

本人不是啥大侠，但是对比较有一点点心得，这里看似容易排除A和B，　因为从表面上来看when这个从句形式没有比较对象，但是注意five times前后比较的都是the number of the gryfalcon。由于前后的主语同类而且谓语都是be动词，所以可以省略。补全了应该是its numbers are now five times greater than the numbers were when...

OG11原来说的是紫本verbal...

Agreement + Structure

The original sentence contains no errors．Each alternative introduces an error or changes the meaning of the original sentence．The semicolon correctly connects the closely related ideas in the two independent clauses．The gyrfalcon is the antecedent for its in the second phrase．

A  Correct．The original sentence correctly uses a singular pronoun，its，to refer to the singular antecedent gyrfalcon，and it properly uses the construction its numbers are．．．greater than．

B  The use of more instead of greater inappropriately implies there are now more numbers，rather than more gyrfalcons．

C  The pronoun their is plural and incorrect since the antecedent gyrfalcon is singular．

D  The pronoun they is plural and incorrect since the antecedent gyrfalcon is singular；comma usage introduces a confusing phrase seeming to modify extinction．

E  Comma usage introduces a confusing phrase seeming to modify extinction．

The correct answer is A．

个人意见： 我觉得 E中的 (E) now with numbers five times greater than（when the use of DDT was sharply restricted in the early 1970’s.）结构应该是独立主格结构： with+n.(numbers)+adj 短语（five times greater than...）,表示伴随状语。伴随状语有自己的独立主语，（这里是numbers）,独立主格有自己的修饰对象（独立主格是非限定成分，一般以主句的某一部分作为逻辑主语）。 而伴随状语是描述被修饰对象的方式、原因、结果或者伴随状态。

http://baike.baidu.com/view/190765.htm （觉得蛮详细的介绍）

而OG11的解释是with型的独立主格的修饰对象不清晰，有修饰extinction的歧义，但是逻辑上应该修饰的是主句主语。把句子主干抽出来看：

The gyrfalcon has survived a close brush with extinction，now with numbers five times greater than（when the use of DDT was sharply restricted in the early 1970’s.）主句中有两个名词，所以with型独立主格的修饰不明晰。（我觉得OG11的这个解释挺牵强的）

ps：a brush with sth （牛津高阶）

when you experience something, or almost experience something, especially something unpleasant

when you experience something, or almost experience something, especially something unpleasant

when you experience something, or almost experience something, especially something unpleasant

再来个例子：OG10-113:

113. Visitors to the park have often looked up into the leafy canopy and saw monkeys sleeping on the branches. whose arms and legs hang like socks on a clothesline.

(A)saw monkeys sleeping on the branches, whose arms and legs hang

(B)
      saw monkeys sleeping on the branches, whose arms and legs were hanging

(C)
      saw monkeys sleeping on the branches, with arms and legs hanging

(D)seen monkeys sleeping on the branches, with arms and legs hanging

(E)
      seen monkeys sleeping on the branches, whose arms and legs have hung

正确答案D带回到原文： Visitors to the park have often looked up into the

leafy canopy and seen monkeys sleeping on the branches, with arms and

legs hanging like socks on a clothesline.

with语法上是可以修饰这三个名词中的任何一个的，而且按照常理应该是修饰主句主语visitors，但是逻辑上只能修饰monkeys。

网上找到个句子：He stared at his friend with his mouth wide open．with his mouth wide open修饰对象不清晰： 是he还是his friend. (没有前后文提醒his friend的性别)。 但是如果这句话变成He stared at his friends with his mouth wide open．那就没有修饰歧义了。

所以我觉得独立主格的修饰对象是根据逻辑含义的合理性，还有和其他答案表达的有效性来选择出来的。OG251不选D E我觉得是把原文的两个并列含义的句子改成一个主句，一个从句的结构，表达的重心改变了。
