Q41:

The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to Southern Chile.

Columbus was the Incan highway, which, over 2,500 miles long and extending

Columbus was the Incan highway, over 2,500 miles in length, and extended

Columbus, the Incan highway, which was over 2,500 miles in length and extended

Columbus, the Incan highway, being over 2,500 miles in length, was extended

Columbus, the Incan highway was over 2,500 miles long, extending

前面是is, can, be able to不是动作性动词，好像不能伴随；　

I choose B (was...extended); Answer is E; 这个伴随状语的问题；

伴随状语总结

13. By law, a qualified physician can only prescribe medicine, protecting the public.

(A) By law, a qualified physician can only prescribe medicine, protecting the public.

(B) By law, only a qualified physician can prescribe medicine, protecting the public.

(D) In order to protect the public, by law a qualified physician only can prescribe medicine.（E）

(E) In order to protect the public, by law only a qualified physician can prescribe medicine.

541 Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging the nuclei of atoms and not splitting them apart, as in nuclear reactors.

(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactors

(B) merging the nuclei of atoms instead of splitting them apart, like nuclear reactors

(D) and merges the nuclei of atoms but does not split them apart, as is done in unclear reactors（E）

(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart

44. Using a Doppler ultrasound device, fetal heartbeats can be detected by the twelfth week of pregnancy.

(A) Using a Doppler ultrasound device, fetal heart-beats can be detected by the twelfth week of pregnancy.

(B) Fetal heartbeats can be detected by the twelfth week of pregnancy, using a Doppler ultrasound device.

(C) (In order to detect意思更合理) Detecting fetal heartbeats by the twelfth week of pregnancy, a physician can use a Doppler ultrasound device.

(D) By the twelfth week of pregnancy, fetal heartbeats can be detected using a Doppler ultrasound device by a physician.（E）

(E) Using a Doppler ultrasound device, a physician can detect fetal heartbeats by the twelfth week of pregnancy.

Choice A presents a dangling modifier. The phrase beginning the sentence has no noun that it can logically modify and hence cannot fit anywhere in the sentence and make sense. Coming first, it modifies heartbeats, the nearest free noun in the main clause; that is, choice A says that the heartbeats are using the Doppler ultrasound device. Choice B contains the same main clause and dangling modifier, now at the end. Contrary to intent, the wording in choice C suggests that physicians can use a Doppler ultrasound device after they detect fetal heartbeats. In choice D the phrase using... device should follow physician, the noun it modifies. Choice E is best.

Q41:

Columbus was the Incan highway, which, over 2,500 miles long and extending
Columbus was the Incan highway, over 2,500 miles in length, and extended
Columbus, the Incan highway, which was over 2,500 miles in length and extended
Columbus, the Incan highway, being over 2,500 miles in length, was extended
Columbus, the Incan highway was over 2,500 miles long, extending

前面是is, can, be able to不是动作性动词，好像不能伴随；

这里不是伴随，是分词短语修饰highway，可以理解为which was extending...的省略形式。

作者: weiyu 时间: 2004-6-12 18:22

LESMM;

句子, -ing; such structure may cause ambiguity. It is hard to discern whether participle phrase is used to modify the aforementioned noun or the whole sentence.

I consider that "extending" should follow the road system or highway immediately.

participle phrase seprates far from the modified noun "road system" or "highway";

To be discussed....

这个似乎是有点搞的，但是就偶做这题的思路来讲，偶没有考虑这个问题，偶看到题目是这样想的：

1.先看所有选项的最前面和最后面的几个单词的区别，这里开头都一样，就看最后的。

2. 看到extended和extending, 偶的第一反映是修饰对象是主动还是被动。－这点没什么理由，就是直觉。

3. 判定主动后，先排除B,C,D, 然后A，是显然不对的，其实在看选项以前看提干时A就否定了。

再贴一个新东方的相关判断原则供参考：

which 修饰对象的判断原则：
名词后面的长、宽、高或名词后面的called分词短语不影响定语从句修饰长、宽、高前面的
名词或者called分词短语前面的名词；定语从句跳跃修饰前面的核心名词。

LESMM:

B的extended不是被动，而是动词的过去时，是主动????

作者: kingsoft 时间: 2004-6-12 20:40

我选E：weiyu斑竹说的be就不能伴随的理论我没听说，

weiyu斑竹的意思是因为主句动作是be，无法伴随动作。但是我印象中应该是可以的。逻辑主语一致就行

weiyu斑竹举的例子里，我觉得主要错误不在于无法伴随，而在于伴随了导致句子意思错

B选项意思错：The greatest road system（是 the Incan highway），（长度超过2,500 miles ）这个部分是作为was后的平行项，还是作为修饰语？？，（并且延伸。。。）前后部分意思上不构成并列

weiyu : 1 形容词短语前有逗号作定语逻辑主语默认为主句主语.

2 两个相同修饰部分之间有连词and不用逗号隔开

前面是is, can, be able to不是动作性动词，好像不能伴随 ? ? 没听过.

可能是我理解的过于绝对了。但是当时看到过一个帖子。只有动作才能导致伴随（动作或结果），而be, can, be able to通常都表示一种状态。以为这样对伴随是个有效的判断。看来不是。请指正。

作者: tianwan 时间: 2004-6-12 23:45

1，目的状语不行，不能说，in order to, sth/sb is. 但是伴随是可以的。

2，The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to Southern Chile.

B.Columbus was the Incan highway, over 2,500 miles in length, and extended

硬伤：was错，必须用is，这是个客观现实。

软伤：over 2,500 miles in length可作状语或定语；而且这个was的作用范围会到extended，会有歧义。虽然was是系动词，从语法上不会被理解成助动词，但是这种was+表语 and ved的结构是个不好的结构。

作者: juan 时间: 2004-6-13 01:59

我好象没听说过is,can后面不能伴随状语的说法.weiyu 举的那些伴随状语的例子,如kingsoft说的,确实是因为其他原因导致不能伴随,而不是因为前面有is,can之类的导致不能伴随.

Q41:
The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to Southern Chile.
A.Columbus was the Incan highway, which, over 2,500 miles long and extending
B.Columbus was the Incan highway, over 2,500 miles in length, and extended
C.Columbus, the Incan highway, which was over 2,500 miles in length and extended
D.Columbus, the Incan highway, being over 2,500 miles in length, was extended
E.Columbus, the Incan highway was over 2,500 miles long, extending
我觉得这道题里,extending...是伴随状语,说明前面提到的over 2500 miles long. 而highway ..exending...没有逻辑错误,就象fungus...extending...也是对的.

1. Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

(A) extending

(B) extends

(D) it extended（A）

(E) is extending

而我觉得如果说B选项错是因为was时态的话,那么正确选项E中也是用was呀.

我觉得选E不选B就是因为E用了伴随状语,更好的说明over 2500miles long是怎么个long的...结构更好.而且B的句子结构 Columbus was the Incan highway, over 2,500 miles in length, and extended 可能让人理解成:the Incan highway extended only in the past ----就象fungus那道题OG解释为什么不用extended一样.

请指教.

(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactors

I don't think E is the best answer. I feel C might be a better answer. Discussions?

这道题首先有个概念：neuclear fusion和neuclear reactor是两个完全相反的动作。那么C的错误就很明显了，C意味着两个动作相同，都是做A而不是做B。

作者: robertchu 时间: 2004-6-13 04:55
有道理。可是，
为什么不能认为C中的 "as nuclear reactors do" 是non-restrictive clause 修饰 "splitting them apart" 呢？

作者: robertchu 时间: 2004-6-13 05:22
仔细想了一下，说C中的 "as nuclear reactors do" 是non-restrictive clause 修饰 "splitting them“的确有些牵强，不符合GMAT风格，虽说日常有人这样讲。

作者: 爱维的天 时间: 2004-12-2 11:42

我觉得这题应该选﹙B﹚啦!

看了前面的讨论，好象没有提到(B)和(D)的主语在那儿

很明显的

﹙B﹚的主语应该是” The greatest road system”，而verb应该是was，它最大的问题应该是..was.. and ved，这个结构不能被接受，但这应该是 EFFECTIVENESS和CORRECTIVENESS的问题，只能说”不好”，不能说”不对”

但

(D)的主语应该是the Incan highway，重点来了，那前面那一大串” The greatest road system built in the Americas prior to the arrival of Christopher Columbus,”，就都变成主语的同位语了，问题就出在这，ETS会把强调的重点择在前面，而同位语放在后面，而且(D)的结构会造成同位语的混乱。

故这题应该选﹙B﹚

请大家给点意见

Q41:

Columbus was the Incan highway, which, over 2,500 miles long and extending
Columbus was the Incan highway, over 2,500 miles in length, and extended
Columbus, the Incan highway, which was over 2,500 miles in length and extended
Columbus, the Incan highway, being over 2,500 miles in length, was extended
Columbus, the Incan highway was over 2,500 miles long, extending

I think the right answer is B

"built" is past perfect (guo qu fen ci) not past simple(yi ban guo qu shi), because roas system can not built it for it self.

The greatest road system was the Incan highway, over 2,500 miles in length, and extended

C,D,E are wrong, except above mentioned it put the very important information of the name of the road in to a nondifining clause

B的逻辑有严重问题：

简化后为：The greatest road system was the Incan highway

这个在OG里面多次说过逻辑是不对的。比如，可以说“李登辉是狗”。但是你能说“狗是李登辉”吗？

如果可以这样说，估计全世界的狗都要出来造反了，除了李登辉家的。

作者: autumn_leaves 时间: 2005-4-8 23:54

怎么弄到最后变B了？？？无法理解，逻辑错误太明显

语法上的歧异：

首先B句子结构可以被理解为三个成分并列，was Incan, was over and was extended

也可以被理解后面两个成分是状语，修饰前面主句

意思上的歧异：

这个更要命，同上面兄弟说的，后面两个东东意思上明显是修饰前面这个存在的东东，把他放到一起并列。。。

意思上太抱歉了吧

OG 56

Architects and stonemasons, huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport.

(A) huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport

(B) without the benefits of animal transport or the wheel, huge palace and temple clusters were built by the Maya

(C) the Maya built huge palace and temple clusters without the benefit of animal transport or the wheel

(D) there were built, without the benefit of the wheel or animal transport, huge palace and temple clusters by the Maya

(E) were the Maya who, without the benefit of the wheel or animal transport, built huge palace and temple clusters

A, B, and D illogically suggest that the palace and temple clusters were architects and stonemasons. For the modification to be logical. Architects and stonemasons must immediately precede the Maya, the noun phrase it is meant to modify. A, B, and D also use the passive verb form were built, which produces unnecessary awkwardness and wordiness. E is awkwardly phrased and produces a sentence fragment, because the appositive noun phrase Architects and stonemasons cannot serve as the subject of were the Maya. C, the best answer, places the Maya immediately after its modifier and uses the active verb form built.

作者: IceOnMe 时间: 2005-4-25 20:02

C的错误是不是在于the road system 后面没有谓语动词而造成 sentence fragement?

The greatest road system built in the Americas prior to the arrival of Christopher Columbus, the Incan highway, which was over 2,500 miles in length and extended from northern Ecuador through Peru to Southern Chile.

同意上面的看法。

在E中，the Incan highway 作为句子的主语，前面的一长窜名词只能看成是the Incan highway 的同位语了，但是有头重脚轻的感觉。另外，我还发现了E的一个问题，就是the Incan highway was over 2,500 miles long的谓语用的是was，但是the Incan highway的长度应该是客观事实吧，不会造的时候是2,500mile，而后来就变化了，我觉得用is 比较合理。

我选B。

我觉得这道题里,extending...是伴随状语,说明前面提到的over 2500 miles long. 而highway ..exending...没有逻辑错误,就象fungus...extending...也是对的.

(A) extending

(B) extends

(D) it extended（A）

(E) is extending

而我觉得如果说B选项错是因为was时态的话,那么正确选项E中也是用was呀.

请指教.

这道题目我还是倾向于B:

Juan举了OG里的一个例子很好，但是我觉得OG那道题目用extending,因为the fungus “is” 是现在还客观存在，extending表示这个动作一直持续到现在。
反观这41题，所有选项用的都是was,说明这个highway是过去存在，现在不存在的，所以再用extending表持续到现在似乎就不恰当了。所以还是选B比E更精准，逻辑上意思更舒服一点感觉

作者: violetleaf 时间: 2005-10-7 17:53

支持B, E 要表达的意思不对啊

作者: xylograph 时间: 2005-10-18 15:54

也更同意B

用“李登辉和狗”来解释是说不通的吧。因为李登辉是个体，狗是范围，个体包含于范围中所以才不能前后颠倒，说成“狗是李登辉”。而这道题里，the greatest road system是单一的，the Incan highway也是单一的，两个不存在包含的关系，只是等价的关系，可以前后颠倒着说的呀。

作者: zhoujian 时间: 2005-12-15 15:40

倒。载在这题上啦

模考的时候我选了E,结果review的时候选了B

首先说说我的理由，楼上有人说B用was逻辑错，我觉得这个是没理由的，因为在哥伦布到美洲，之前“曾经”最大的那个公路系统，现在已经不存在了，倒是很符合用过去式的逻辑

另外有人说XX人是狗倒过来说狗是XX人，这个例子用在这里不合适。因为这里有用了the greatest road system,特指曾经最大的那个公路系统，特指最大的这一个，而不是泛指，所以逻辑上没错。

有人说road system不能做extend的主语，这里extended是一个过去式啊，和was平行，有什么不可以？

下面这个例句来自longman,说明road system完全可以做extend的主语。

The River Nile extends as far south as Lake Victoria.

至于E,其实我毛病也没看出来，但觉得E有改变句子重心结构的嫌疑，因为原句重心是强调XX是XX,而E变成强调这条路的长度了。前面那个同位语也太长了，感觉重心明显不对。

所以还是认为B比较好。

希望大家能来反驳我的观点，请指教！

因为B中的was紧跟哥伦布，所以会有修饰哥伦布之嫌，而E避免了这个问题，所以E比B好一些，哪位能解释一下C不好在哪里？是没有主句吗？谢谢！

作者: fuyun 时间: 2005-12-26 00:05

B. Columbus was the Incan highway, over 2,500 miles in length, and extended

除了逻辑意思不对，over 2,500 miles in length 修饰有歧义吧，到底是修饰the greatest road system, 还是 the Incan highway？

作者: wzparete 时间: 2006-2-16 13:16

这里涉及时态问题：B，extended要用extends就对，表示客观存在用一般现在时。

E对，前半句是同位结构，extending短语修饰主句主语。

作者: 麦麦麦 时间: 2006-2-16 13:50

但E里面不是也用了was过去时吗?

作者: huhulala 时间: 2006-6-25 09:28

我觉得根本就没有什么extend要用现在时的问题，看一下所有选项，前面都是was，后面的都是extended,除了extending。也就是说这个句子在说一个过去的事情，估计现在这个greatest road system都不在了。所以不需要讨论时态问题。

再来b的问题，这里was and extended是平行的，over 2500 miles作为状语，放在was and extended中间勇逗号隔开，会产生歧义的，是修饰前面的分句was还是后面的分句extended？虽然好像都可以。

最后，e的extending最伴随状语，是用来说明怎么个in length法，是这个road的特征，本来也不代表任何时态。不过说实话，我真分不清分词（现在分词，过去分词）做定语还是状语的情况。

比如

Many financial experts believe that policy makers at the Federal Reserve, now viewing the economy as balanced between moderate growth and low inflation, are almost certain to leave interest rates unchanged for the foreseeable future.

A. Reserve, now viewing the economy as balanced between moderate growth and low inflation, are

B. Reserve, now viewing the economy to be balanced between that of moderate growth and low inflation and are

C. Reserve who, now viewing the economy as balanced between moderate growth and low inflation, are

D. Reserve, who now view the economy to be balanced between that of moderate growth and low inflation, will be (A)

E. Reserve, which now views the economy to be balanced between moderate growth and low inflation, is

说viewing做定语修饰policy makers好像也行，说它做状语修饰are certain也行吧？我真搞不清楚了。做题的时候一般就排除法，最后混淆选项就靠语感，，，

The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, over 2,500 miles in length, and extended
from northern Ecuador through Peru to Southern Chile.

我本来也是选B，后来仔细看了题目后发现B不妥，over 2,500 miles in length,是插入语，extended和was是并列的，主语是greatest road system ，所以是错的。

楼上的照你说的为什么不对呀？最greast的公路系统是Incan Highway，它长多少，延伸到~~~~~~~~~

所以既然greatest road system 就是Incan Highway, 不管Over~~是修饰greatest road system, 还是修饰Incan Highway,不都是一个逻辑意思吗，所以不会造成歧义呀？

作者: michaelyun 时间: 2006-8-15 20:49
C,D,E是不是句子的重心发生了转移？对于句子重心的问题，是否应该忠于A？

作者: peter777 时间: 2006-10-18 20:44

B的逻辑有严重问题：简化后为：The greatest road system was the Incan highway这个在OG里面多次说过逻辑是不对的。比如，可以说“李登辉是狗”。但是你能说“狗是李登辉”吗？"

强烈同意，这个语法题太扣了

作者: 高宝拉 时间: 2007-2-7 12:13
嗯～～还是E更好一些。。。。

作者: LOUI1121 时间: 2007-2-11 14:45

请问,把HIGHWAY说成THE GREATEST ROAD SYSTEM有什么逻辑错误.

李登辉是狗的例子虽然不是很贴切,但是作为中国人我还是要顶!

ROAD SYSTEM就是公路系统呀,HIGHWAY就是由公路们拼起来的,当然可以称之为SYSTEM.其实这只是次要的, B对的真正原因是因为逻辑正确! 如果逻辑改变, 语法上再正确, 也是错!

支持E。

作者: jesdy 时间: 2007-7-7 13:33

可不可以这么理解

B Columbus was the Incan highway, over 2,500 miles in length, and extended

b选项里 over 2,500 miles in length 既可以修饰前面一句话the greatest...was the Incan highway，又可以修饰后面一句话and extended。。。

og里经常有这样的解释，一个分词短语或插入语放在中间既可以修饰前面的，又可以修饰后面的，就造成了歧义。

我认为这道题排除ＢＣＤ的最简单的办法就是：大家注意：in length　是　long 的故意复杂化阿 ets肯定是倾向于更加简单的long的表达方式的阿

Ｂ到底逻辑上有什么错误啊？

作者: wsdoll 时间: 2007-8-19 07:26
这道题选E吧？怎么这么多gwd有争论的。烦没有官方答案的题。

作者: janezh 时间: 2007-10-9 13:42
如果E对，则the Incan highway was over 2,500 miles long 是主句，The greatest road system built in the Americas prior to the arrival of Christopher Columbus, 和 extending from northern Ecuador through Peru to Southern Chile.是从属部分，做什么成分？各修饰什么？请NN帮忙解释一下，看了众多的XDJM的想法，还是不能说服我选E，我认为B对。 B的逻辑意思完整，在从语法上不能确定的时候，我还是选择逻辑意思完整的吧。

A. Columbus was the Incan highway, which, over 2,500 miles long and extending

B. Columbus was the Incan highway, over 2,500 miles in length, and extended

C. Columbus, the Incan highway, which was over 2,500 miles in length and extended

D. Columbus, the Incan highway, being over 2,500 miles in length, was extended

E. Columbus, the Incan highway was over 2,500 miles long, extending

E我没有看懂啊，这句子是通的？the Incan highway was over 2,500 miles long是Christopher Columbus的同位语？不然的话，第一个分句和第二个分局怎么之间怎么会没有连接词？...

作者: latinjazz 时间: 2008-6-13 15:37

这提我一开始选C

没选B是因为the greatest road system was the Incan highway,over 2,500...

highway逗点之后没有代辞或Ving, Ved的结构, 照前文也不能构成插入句, 因此不选

但看了看C的which好像有指称上的问题

作者: hoopdon 时间: 2008-6-30 04:50
B 的问题应该是 and extended.... 的语法作用有歧异

过去分词在句尾优先就近做定语，修饰名词，这种情况下extended...和over 2500...并列修饰 incan highway

同时，由于exteded前边有个and，又可以理解为和was the Incan highway并列，是主句的一部分，而over 2500...是插入语。

因此这个extended的作用无法确定

我觉得是这个样子的～～

作者: dingxiang 时间: 2008-7-18 17:04

GWD6-Q41:

B. Columbus was the Incan highway, over 2,500 miles in length, and extended -->B的问题请见OG11－104：典型的从语法上如何筛选分词还是谓语动词的例子。简单的说就是，

and前后同一主语, 前后动作并列, 则S+V1 and V2 ~~中间无逗号, V1V2 共享一个主语
and后面有逗号, 则S+V1, and 代词 +V2 ~~V1V2 前面均有主语

所以这里 extend d的主语仍然是system ，所以and前面不能有逗号

E. Columbus, the Incan highway was over 2,500 miles long, extending 同位语，GMAT偏爱的形式，在加上分词extending作伴随状语，语法上逻辑上都没有不妥。

作者: yifeir 时间: 2008-7-31 17:22

以下是引用autumn_leaves在2005-4-8 23:54:00的发言：

怎么弄到最后变B了？？？无法理解，逻辑错误太明显

语法上的歧异：

首先B句子结构可以被理解为三个成分并列，was Incan, was over and was extended

也可以被理解后面两个成分是状语，修饰前面主句

意思上的歧异：

这个更要命，同上面兄弟说的，后面两个东东意思上明显是修饰前面这个存在的东东，把他放到一起并列。。。

意思上太抱歉了吧

解释的好！最简单的最明白。呵呵。多谢

作者: helenzane 时间: 2008-10-27 00:44

我能问个别的么？看到A，我想问，比如“***，which,***”这种结构怎么理解？

另外，我还见过比如“***which,***，###”这样怎么理解？

作者: wwzzxx 时间: 2008-12-2 03:28
回楼上的，你所指的which从句是非限定性从句，11版og sc部分开头就是对此的详细解释。

此题必选E

作者: balabaladou7 时间: 2009-3-12 14:13

这题的讨论思路好怪~

新PREP已确定答案：E

下面是我的分析：

The greatest road system…the Incan highway was over…, extending from…to…

A. which多余或者说which后面不是个分句。

B. extended被动形式错，句意变成了highway被延伸了，实际上延伸是highway主动发出的动作。and extended变成MingLiU","serif"; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">和was the Incan highwayMingLiU","serif"; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">平行，改变了句子的意思。

C. in length不如long简洁，extended被动错。整个句子没有谓语。

D. being使用wordy，in length不如long简洁，was extended变成MingLiU","serif"; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">和was the Incan highwayMingLiU","serif"; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">平行，改变了句子的意思，且被动使用不当。

E.
正确。Extending做状语修饰主句。

请指教！

作者: lupisces 时间: 2009-4-20 00:18

这里extend虽然可以看成主动，（与前面的was highway分开）但是中间的插入语导致这个逻辑意思上不好

was the Incan highway, over 2,500 miles in length, and extended

tianwan的解释最好

不是被动吧，这里的extended只是过去式而已

C的and extended能否看成which extended。。。。？

E实在是看不懂，太复杂了，。。。。

作者: sabrina324 时间: 2010-3-19 17:37
我个人认为；这里是考同位语的用法，同位语是GMAT优选结构
The greatest road system（ built in the Americas prior to the arrival of Christopher Columbus ）, the Incan highway was over 2,500 miles long, extending from northern Ecuador through Peru to Southern Chile.

作者: kkjj2222 时间: 2010-8-31 01:29
同位语可以放在句首么？
