标题: OG 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.

OG的解释:Choices D and E wrongly use a phrase introduced by now with to modify The gyrfalcon. 能不能得出对介词短语修饰的一点原则:

1,前面没逗号,修饰的是前面的名词
2,如果前面有逗号,修饰的是主语,如OG251

这点我一直有疑问,请大家帮助。谢谢。

joywzy mm,要注意看choices D and E....后面的话:In both choices, the phrase....是说now with...看上去与with extinction 平行,引起混淆
作者: joywzy    时间: 2003-11-26 11:17
我明了D和E是错的。可是我想问的是根据OG对D和E错误的解释,是不是可以认为介词短语(WITH),如果有逗号,修饰的是主语。

如果没法判断,介词短语(WITH),如果有逗号,修饰的是什么呢?这一点我一直不明白。谢谢。
作者: bigcamel    时间: 2003-11-26 11:30
我没有说清楚。 看og解释“choices D and E wrongly use..."的后面的一句话“In both choices, the phrase....“是说now with...看上去与with extinction 平行,引起混淆。
既然ets认为“ , now with..."可能被(错误地)认为与“with extinction"平行,那么就不能认为介词短语前面有逗号,锈蚀的一定是主语
作者: joywzy    时间: 2003-11-26 11:48
是这样啊,我明白了。谢谢bigcamel

那选项A里its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's.是numbers和什么做比较呢?我觉得这里than when用得好像不idiomatic哦,大侠还能帮我解答一下吗?谢谢了!


作者: dxwei2008    时间: 2004-4-5 22:51
With在逗号后面的用法一般在GMAT语法中是用来跳跃修饰的。一般我们大家都知道,定语从句是不可以进行条约修饰的,但是with短语是没有限制。下面这个例子是with用法的一个说明。
答案没有使用任何定语从句,因为从句要修饰的对象monkey相隔太远,所以使用了with结构。请体会!

1.       Visitors to the park have oftenlooked 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(D)

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

D

now 和 when ...比较
作者: mnwo    时间: 2004-7-13 10:54

是不是than 后省略it is


than做准关系代词?


作者: ztlbox    时间: 2004-7-28 22:19

对than后面的比较也有疑问,省略的是they were吗?哪位大侠能讲讲关于比较后面省略的原则,印象中比较后面省略的情况比较少见,多数是成分不全,要求补全的情况。

还有关于numbers, 为什么不是number呢?numbers 不是许多大量的意思吗,能用five times 修饰吗?

I have the same question as 2045977 and ztlbox.

Any one else could help?

Than 可以做代词 如as一样, 所以后面省略了are its numbers.

why here use "numbers" instead of "number", can we say " number is five times more than"?
作者: zikzik    时间: 2004-8-20 21:55

为什么用its numbers 而不用their numbers. its numbers看上去半单半复,感觉很是别扭?


作者: agk99    时间: 2004-8-22 12:04
我想是因為,原題主詞是The gyrfalcon,所以後面才接its number
作者: chasemba    时间: 2004-10-28 22:34

当用于sth's numbers 表示数量的概念.

当用于 the number of ... 表示一个数. 可以体会一下.

以下是引用horsefish在2004-8-13 1:00:00的发言:

为什么不是省略的语序为than its numbers are  而是把are放在前面?类似的顺序还有OG224:Inuits here were isolated from european longer than were Inuit there.


作者: 我爱欧洲    时间: 2005-6-8 22:34
刚才看了OG224LES的解释:

GMAT比较结构中,倒装不是重点,即不会考只有倒装的区别。倒装结构主要有两个用途:

1.强度要修饰的部分,即将要强调的部分前提。

2.平衡句子结构,即若正常语序造成头重脚轻的话,需要倒装。


RHOD的解释:


比较句里面多用倒装,我觉得这主要是因为比较句里面有省略。如果主语和系动词或主动词之后有省略,那么就是用倒装。


倒装与否不是关键,基本上还是看是否有歧义。


作者: wkw5336280    时间: 2006-7-31 13:55

我还有一个疑问,比较的话不是要比较对象对等吗??

为什么A中那个than后面没有出现those指代numbers???

作者: dormousedzc    时间: 2007-12-1 16:04

1.我选择E.  以为能回避开its numbers这种看上去心慌慌的表达方式.  结果两次都栽了.

现在回过头来看, 虽然its numbers是有些奇怪,但是在their缺乏指代的情况下,its numbers就很可能是正确的选项,没有必要再进一步回避了,否则单复数这个考点就白考了.     NN看这种考试思路可行么?

2.有人摘录OG10对E.选项的解释,说逗号后面的with numbers与前面的with extinction会形成平行结构.所以不正确,对此我是这样理解的,请NN指正:

鉴于a close brush with(该词组通常带有敌意或警告性的接触)extinction 意思是"一度面临绝种"的意思,那么后半句(a close brush) now with numbers five times greater than的意思就成了"一度曾面临数量是1970年代5倍的局面".-------数量大幅度增长显然是好事,不应该含有敌意或警告的意思,所以一定不能用now with...,而必须另起炉灶,构建完全独立的一套句子结构.    所以A.对.

55555,图片点击可在新窗口打开查看 我在做这题时,根本不知道a brush with的意思,  必定,肯定,一定会追求平行对称, 所以也必定,肯定,一定会错. 只能感叹一句:母语TMD就是有优势呀!图片点击可在新窗口打开查看

现在OG11中的解释说:E. Comma usage introduces a confusing phrase seeming to modify extinction.   新的解释到是让我糊涂了,with...结构什么时候可以修饰前面的宾语了?    不是一向都优先修饰主语么,怎么现在挑错都如此自然,和谐?

这日子没法过了.   S.O.S

关于OG11的解释,同问!


作者: 卖菜熊    时间: 2008-2-1 15:57

是啊,OG11的解释很奇怪,比OG10说两个WITH短语可能构成平行更难理解。希望有NN路过指教!!

作者: ywgre    时间: 2008-6-7 23:13
谢谢dormousedzc关于D、E错误的解释,有些理解了,,,不过,说是可以构成平行也不太正确吧,不需要and来连接吗,所以关于平行是可以排除的,,不知理解对不对,是不是有now就不需and了
作者: sky85    时间: 2008-7-22 20:34
我也不明白OG-11的解释. A跟E到底怎么比较得到呢? 我看到说定语从句尽量就近指代, 而介宾短语可以跳跃修饰前面主语阿, 为什么这里修饰distinction呢? 从逻辑上判断, 也不可能修饰extinction阿. 请NN们指正~
作者: aeoluseros    时间: 2008-8-16 07:46

这道题目。。。我对OG10和楼上各位所说的OG11(没在OG11里看到这个题啊,是第几题啊?)关于E选项的解释都不理解。。。

OG10:

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.

如ywgre所说:说是可以构成平行也不太正确吧,不需要and来连接吗,所以关于平行是可以排除的,,不知理解对不对,是不是有now就不需and了

OG11:没在OG11里看到这个题啊,是第几题啊?

dormousedzc所说:with...结构什么时候可以修饰前面的宾语了? 不是一向都优先修饰主语么,怎么现在挑错都如此自然,和谐?

而且我还再加一点点疑问:

OG10里:Choices D and E wrongly use a phrase introduced by now with to modify The gyrfalcon.这句话什么意思啊?now with怎么就不能修饰gyrfalcon了?the gyrfalcon with the numbers这个说法很对啊?


作者: aeoluseros    时间: 2008-8-16 07:59

OG11原来说的是紫本verbal...

Agreement + Structure

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

A  CorrectThe original sentence correctly uses a singular pronounitsto refer to the singular antecedent gyrfalconand it properly uses the construction its numbers are...greater than

B  The use of more instead of greater inappropriately implies there are now more numbersrather 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 singularcomma 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

这里的解释就清楚多了...momo啊momo...


作者: woshino1    时间: 2008-10-7 06:23
试着解释一下:根据白勇的语法:分号连接的是两个分句,所以,A中的its指的是主语gyrfalcon;而逗号连接的要么是插入语要么是介词短语进行修饰,如E项now前面是逗号,后面的介词短语进行修饰,如果按照就近原则的话,now就有可能修饰extinction.

期待进一步讨论。

aeoluseros斑斑,你看11对DE的解释,我不明白啊?

E  Comma usage introduces a confusing phrase seeming to modify extinction

with...结构什么时候可以修饰前面的宾语了? 不是一向都优先修饰主语么。我一直的认为是with没有逗号修饰前面的名词或者做状语修饰主句主语都可以,所以有歧义的。但with前 面有逗号基本都是做状语,或者是独立主格结构的。这里怎么会也可以修饰前面呢??我觉得10的解释还比较好懂,11的就完全不明白啊?:

请斑斑指点!!!


作者: aeoluseros    时间: 2008-11-28 19:56
前面是完成时,所以with结构是不会表示伴随状语的(with做伴随状语和独立主格是需要与前面的谓语动词同时发生)...所以只能做定语修饰前面的extinction.
作者: sharon213    时间: 2008-11-28 20:01

可是“,with”我在og中看几乎所有都是做状语的啊,没见过做定语的


作者: sharon213    时间: 2008-11-28 20:04
还有就是og10上说的到底是修饰extinction还是和他平行呢??平行难道不要加and直接有now就可以么?
作者: aeoluseros    时间: 2008-11-28 22:07

with引导的介词短语始终是有做定语的功能的,只是放在逗号再加with这样子表达并不好,不如去掉逗号或改为定语从句,在GMAT里面貌似是错误的。

如果now是连接性副词那么那样的平行是可以的...可是我没有查到now可以做连接性副词,只有查到then可以。不过两者很相似,有理由相信,now可以连接两个并列成分。

OG10和11的解释应该都是对的,也就是同时存在两种歧义。


作者: sharon213    时间: 2008-11-29 23:07

谢谢斑斑,那是不是就是有逗号的with放在句尾也可以做定语修饰前面的名词的?

就是这样SVO,with。。。这样with也是可以修饰O的?只是这样不好,不如分词和定从来的直接?是这样理解的么?

作者: lixieyunan    时间: 2009-3-16 23:23
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...

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。
