A和C应该是第一眼排除的因为是the company单数嘛(确定性规则要第一使用，别使用那种抹零两可的规则）
第二眼看到的区别是from to 没什么都一样
第三眼看到的是D和E拉，大家看选什么呢，明显E拉因为which就是修饰market了，
事实上，新东方讲的什么跳跃修饰是有问题的，非限定性定语从句是完全是可以跳跃修饰的，因为他不限定修饰对象必须跟在which的前面，而限定性定语从句是不能条约修饰的，所以问题不在修饰上
在哪里？？在increase in上，D中的选项increase事实上是做不及物的，请问做不及物的话，company怎么能increase????只能rate 或者share 才能increase吧！！！
大家看这个in在这里很明显是考点，因为在5个选项里increase既有做及物的又有做不及物的，我说拉，差异就是考点，D用不及物从本质上来说，是逻辑意思不对了！

这到题我要红笔标出来
请问commodities什么意思？日用品
aluminum是什么？铝吧
metal是什么？金属吧！！
我看了大家的讨论气死了
工业用品和日用品是两个范畴吧！！请问连范畴都不一样，怎么来such as啊，怎么来举例啊1！！！！！！！！！我们说fruit such as apples, oranges and banans都是要后面是属于前面的范畴才举例吧！！
这里就是like a, b....的形式（新东方说的对，AB要一类东西，这个规律我想大家都知道吧！）
就是说正如铝和其他金属的市场一样，日用品的市场仍然也很坚挺
在ETS看来这是最简单的题目了

偶选A
BDEunlike 的用法不对
C的话which指代前面整个情况不能这样用的，其实其他选项有cicumstance就是告诉你要选他了，which是肯定不能指代整个句子的，（这里是说没有法律限制这个情况导致了鱼的过度捕杀）OG上和补充材料上无数的题目证明了这一点！
另外有人说没见A中AS的用法
请注意如果一定要弄清楚LIKE和AS用法
AS和LIKE都可以表示象什么什么一样正如什么什么的意思
区别是AS连接句子
LIKE连接名词
我坚持选A

谢谢gigi！！！偶要花时间好好研读一下。
先消消气 (菠萝是没有啦，偶知道苹果你应该也喜欢的说)
下面偶要撞抢口啦！
关于as作比较的用法，一般来说是As A do, B do. 正如A如何如何，B如何如何。
但是这里的是：As A do, B do not...，即前后是相反的。是否可以这样用？实在是看到的例子很少，不懂的说。
像like就比较简单，可以用unlike表不同。谢谢！

楼主：我改一下标题便于存查，不要介意哈。
对了，今天下午天暴热
所以发贴讲话口气可能有那么一点点点的不谦虚
请大家多多见谅
偶不是故意的
实在是天气真TMD又热又闷
在看到你们讨论所以急脾气就上来了
大家多多见谅
偶说的东西大家只能做参考
提供一些思路吧
gigi, 这里B选项的时态不对，还是很迷惑：
困惑1，相信权威：TOEFL阅读中有这样一个句子：
Over 99 percent of all species (that ever existed) have become extinct
困惑2， 偶的理解：
B的时态表达使逻辑更清晰。这里appeared并不是说某个时间点一下子出现。而是强调一个先后顺序。即living creatures先出现，然后从出现这个时间点开始到现在的一段时间内逐渐灭绝了。即一定是先出现后灭绝。
Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
LES，您太客气了，受之有愧！
gigi NN提供的思路，还是应该再讨论细致，明确一下的好。
所以，有不明白的跟贴或到相应的贴子里问问。
呵呵,gigiNN 我先声明,我可不是抬杠的说!大家讨论讨论嘛
非限定性定语从句是完全是可以跳跃修饰的，因为他不限定修饰对象必须跟在which的前面，而限定性定语从句是不能条约修饰的，所以问题不在修饰上
gigi可能是打字时打错了, 我看到的应该是限定性定语从句可以跳跃修饰才对,而且一般来说采用的是A of B that的形式,A和B一个是单数一个是复数,然后用that后面的动词是否是单数来判断定语从句修饰的是A还是B,跳跃修饰A的现象可以合理存在.可恨的是一时没找到现成的例子, 显得不够eloquent,不过搜索weiyu GG很在行,也许我们可以问问他能否短时间找到
关于commodity, 大家可能一直有个误区,认为它是日用品,可实际上,这个词的第一个意思是商品,第二个意思是农产品或矿产品
另外看看E: the market for recycled commodities, like the commodities of aluminum and other metals, remains... 如果like在这里表相似, 那么无论如何market都不能象(like)commodities的. 如果要说后一个commodities修饰前一个commodities而不是market, 连着两个commodities是不是有点重复而且冗余,为什么不说like those of aluminum and...另外是不是把逗号去掉才好? go and buy me some fruits like apples and oranges; 更何况,我觉得这里应该是例举的意思,用such as 更为合理,而且也是ets 的关于like和such as的考点
marie:非限定也可以像你说的那样跳跃的。如： 复数 of 单数， which are....
据我观察，以前凡是讨论跳跃的贴子最后都没有得出最后的结论，只要一讨论跳跃就会死得很惨~~~
无语……
偶是这个意思啊？marie，难道不对吗？我觉得E也是这样的意思啊？

大牛姐姐。 偶有一点小小问题，不要笑我没水平。
我选b来着 然后您说e 我就想e 后来我觉得e和b都对了
这里请给具体解释一下b为什么不对行不？我认为 一些过去出现过的动物中的９９％ 到现在已经灭绝了 好像对的吧。当时就是觉得bde时态对，去掉d ，e 没见过不敢选所以选了个倒装，感觉 ets很喜欢到装的 偶是这个意思啊？marie，难道不对吗？我觉得E也是这样的意思啊？
living creatures that appeared on Earth， appeared是出现过，暗指现在已经没有了。而have appeared 是指过去出现,到现在（至少有些）还存在。
同感只要一讨论跳跃就会死得很惨~~~
只要一碰上跳跃我就会死得很惨~~~Sigh
到底什么可以跳，什么不可以跳。总的感觉ETS总是对的，我总是错的。
象its share of the $21 billion book market in the country, which ranges

if "commodities" and "aluminum and other metels"可比（同一类）是不是D对？
living creatures that appeared on Earth， appeared是出现过，暗指现在已经没有了。而have appeared 是指过去出现,到现在（至少有些）还存在。
先别怪偶！只是想举个直观点的例子：
You were born in 1980. 是出生过，暗指现在已经×××？
还是偶们要说：
You have been born... ?
一般过去时指：
1. 在确定的过去时间里所发生的动作或存在的状态。
2. 表示在过去一段时间内，经常性或习惯性的动作

2. 表示在过去一段时间内，经常性或习惯性的动作
哈哈，被mm发现了。
偶也想到了，但是觉得对于一般过去时所表达的含义应该没有问题的吧？
偶的意思是：不能说一般过去时含有“出现过，暗指现在已经没有了”这层含义。
如：That skyscraper was built last year. 不会认为这幢楼今年就不存在了吧？
哦？好像有点意思的说！让偶想想！谢谢！
狗狗，这里的born当然是verb!
关于是adj. 的用法，请看下面longman上的所有解释：

someone who has a strong natural ability to lead, play music etc
the skill of a born actor
2. born loser
someone who always seems to have bad things happen to them
3.in all your born days
old-fashioned used to express surprise or annoyance at something that you have never heard about before
In all her born days she had never heard anything like it.

if "commodities" and "aluminum and other metels"可比（同一类）是不是D对？
如果你这样说
把句子抽象出来的话
其实就是
market, such as aluminum and other metels
后者不是前者的一个类别，这题应该不是举例的，
举例前后必须是包含与被包含的关系
在补充材料上有道题目
allergires such as to milk
这里补出to的原因就是因为allergires不包含mile,不能直接说allergries such as milk。
其实ＴＯ前面还省略了an allergry
至于你们讨论的时态问题

1. born leader/musician/teacher etc
someone who has a strong natural ability to lead, play music etc

3.in all your born days
old-fashioned used to express surprise or annoyance at something that you have never heard about before

这里我讲是ADJ, 是参考下面的:
http://dictionary.cambridge.org
born (BEGIN TO EXIST) [Show phonetics]
adjective
1 be born When a person or animal is born, they come out of their mother's body and start to exist:
She was born in 1950.
We saw a lamb being born.
Diana was born into an aristocratic family.
Ann was born and brought up in Ealing.
2 having started life in a particular way:
The toll of babies born with AIDS is rising.
Stevie Wonder was born blind.
以前我也认为born是被动式而已, 但看了字典才晓得这里表状态.....
。看看longman的关于born 作为verb的解释：这题我也选B, 我对(D)(E)的排除是appear 和vanish两者都用完成式, 未能体现两动作一前一后......相关题目可参考LZM第三篇R-3或是XDF-S6-10

Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
呵呵.....我说的就是dreadpower版主的意思....可能我表述不当.....
就说说have appeared跟have vanished这两个时态,
因为原文的逻辑意思是出现在地球的五百种生物已经消失了,
所以我认为appear发生在vanish之前, 如果都用现在完成式, 能表达一前一后的关念吗?!
我不敢认同....因为现在完成式有表达从过去到现在的意境.....
拿我说的例子来看:
Some buildings that were destroyed and heavily damaged in the earthquake last year were constructed in violation of the city’s building code.
(A) Some buildings that were destroyed and heavily damaged in the earthquake last year were
拿(A)来看, 两个都用过去简单式, 也是分辩不出一前一后的概念
B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
谢谢楼上两位的解释！
但是还有一个问题，反对方（选E的朋友们）说 five hundred million different species 前面必须加the，原因是后面有 that 定语从句做修饰，特指a particular group。请问你们怎么看这一点？谢谢！

The choice must be C。agree with opeman.气死了,这个帖子发了三遍都没成功!!!
偶觉得这里面还有个that作为限定性定语从句修饰species的问题
如果是99% of ## species that appeared on earth感觉是出现在地球上的##种物种里的99%现在已经灭亡了,言下之意: 出现在地球上的物种不止这##种
而99% of the ## species that appeared on earth加了个the,就明白表明出现过的物种是##个,其中99%....
大家可以参考某人解放奴隶那题
Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
A. Five hundred million different species of living creatures have appeared on Earth,nearly 99 percent of them vanishing.
B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
1，the不可少：
the 500,000,000 different species of living creatures that have appeared on Earth, 就是这500,000,000种。
500,000,000 different species of living creatures that have appeared on Earth，没有the，就变成了曾出现在地球的许多种类中的500,000,000种。
所以，没有the，这个99%的内容就不知道是什么了，到底是什么的99%呢？a，假定曾出现在地球1,000,000,000种，这500,000,000种是其中的哪500,000,000种呢？b，你可以假定1billion种，他可以假定2b种，到底应该总共曾出现多少种呢？至少作者不应该留下这个疑问的，变成让读者猜猜猜，急死偶们没商量。所以这个the是很关键的。
2，have appeared是可以的，而appeared看起来有些不爽。
一般过去时表示确定的过去时间，现在完成时表示不确定的过去时间，但本题没有时间状语，所以不用这一点判断。
一般过去时与现在的情况没有联系，现在完成时与现在的情况有联系。从本题的意思上看，应该是有联系，到现在为止的500，000，000种。所以一般过去时是错的。答案应该是E。
偶的理解是：如果说用that...来限制species的话，那就是说曾经在地球上出现过的物种....，言在之意没有出现过的物种...., 请问没有出现过的这种说法有没有意义呢？
要说slave这题，请看跟所讨论的B选项结构类似的是C选项，而ETS却偏偏没有具体讲有没有the的问题。B,D与A选项主要的区别不是有没有the，而是more than的位置不同，造成意思不同！
154. In 1791 Robert Carter III, one of the wealthiest plantation owners in Virginia, stunned his family, friends, and neighbors by filing a deed of emancipation, setting free the more than 500 slaves who were legally considered his property.
(A) setting free the more than 500 slaves who were legally considered
(B) setting free more than the 500 slaves legally considered as
(C) and set free more than 500 slaves, who were legally considered as
(D) and set free more than the 500 slaves who were legally considered（A）
(E) and he set free the more than 500 slaves who were legally considered as
This sentence requires that the participial phrase setting free... connect to the gerund construction by filing a deed...; it was the filing of a deed that made possible the setting free.... Choices A and B establish this connection, but only A, the best choice, completes the participial phrase appropriately. In choices B and D the misconstructed phrases set[ting] free more than the 500 slaves... mistakenly suggest that Carter set free slaves that were not his own. Choices C and D distort meaning by paralleling stunned and set free, as though these were two separate and independent actions. E begins a second independent clause, which—though grammatically acceptable—again distorts the meaning. In choices B, C, and E, considered as is unidiomatic.
一般过去时表示确定的过去时间，现在完成时表示不确定的过去时间，但本题没有时间状语，所以不用这一点判断。
我查了一下文法书:
Simple Past: the simple past indicates that an activity or situation begun and ended at a particular time in the past.
Present perfect:the present prefect expresses the idea that something happened ( or never happened) before now, at an unspecified time in the past. The exact time it happened is not important.
If there is a specific mention of time, the simple past is used.
ex: They have moved into a new apartment.
ex: They moved into a new apartment last month.
所以(E)的答案会更好, 因为现在完成式可指动作发生在过去不确定的时间....
PS:补充一点, 我刚讲的是现在完成式的另一种用法, 而我们所常用现在完成式是"从过去到现在的动作"
狗狗，你也投向大N们了？
dreadpower，再来看看呀！

呵呵....我是在追求真理, 可不是批斗大会吧!!
再说我的症结点是时态, 既然完成式可以代表过去动作发生在不确定时间, 句型又是ETS最爱, 干吗不选?!
Hi,
I'm pretty sure that D is the correct answer.
First, "commodity market" in the sentence refers to raw material market, such as the New York Merchandise Exchange, on which options of all kinds of raw materials,such as aluminum, gold, silver, are traded. So, obviously “such as” is better than “like”.
Second, the clause “such as aluminum and other metals” is a non-restrictive clause modifying commodities, so commas are needed here to separate the non-restrictive clause from the main idea – “the market of commodities remains strong”.
Discussions welcome!
By merging its two publishing divisions, the company will increase their share of the country's $21 billion book market form 6 percent to 10 percent,a market ranging from obscure textbooks to mass-market paperbooks.
A. their share of the country's $21 billion book market form 6 percent to 10 percent,a market ranging
B. from 6 percent to 10 percent its share of the $21 billion book market in the country, which ranges
C. to 10 percent from 6 percent in their share of the $21 billion book market in the country, a market ranging
D. in its share, from 6 percent to 10 percent, of the $21 billion book market in the country, which ranges
E. to 10 percent from 6 percent its share of the country's $21 billion book market, which ranges
B is correct. First, it’s the market share of the company that’s discussed, obviously “its share” should be used. So out A, C. D is out because it’s awkard. B is better than E because “from ... to ...” is idiomatic, but “to...from...” is not. The “which” in B is modifying “book market in the country” – and it’s acceptable.
There are no legal limits, as there are for cod and haddock, on the size of the monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.
A. There are no legal limits, as there are for cod and haddock, on the size of the monkfish that can be caught, a circumstance that contributes to their depletion through overfishing
B. There are no legal limits on the size of monkfish that can be caught, unlike cod or haddock, a circumstance that contributes to depleting them because they are being overfished.
C. There are legal limits on the size of cod and haddock that can be caught, but not for monkfish, which contributes to its depletion through overfishing.
D. Unlike cod and haddock, there are no legal size limits on catching monkfish, which contributes to its depletion by being overfished.
E. Unlike catching cod and haddock, there are no legal size limits on catching monkfish, contributing to their depletion because they are overfished.
C is correct. First, the paragraph is discussing monkfish’s depletion, so “its depletion” should be used. Out A, B (them) E. In D, “Unlink ..., there are ...” and “being overfished” are both problematic. So, C stands. C is not perfect though, “which” in C refers to “no limits for monkfish”. This is a little different from the typical usage of "which" in GMAT. But this usage is OK in general English, and in any case it’s a lesser sin than the other choices.
B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
I choose E. Here “five hundred million different species” is a definite noun phrase, so article “the” must be used in front of it. Therefore B is out. In addition, “appeared” in B implies that all the species are all gone now, which is not true. So E is a better choice.
The ninetheenth-century chemist Humphry Davypresented the results of his early expreiments in his "Essay on Heat andLight", a critique of all chemistry since Robert Boyle as well as avision of a new chemistry that Davy hoped to found.
A is correct. E is out because it sounds like H.D. was also critiquing “his own envisioing”. Similarly, D is out because it sounds like HD was also critiquing “a vision of ...” (his own vision). A is correct because “a critique” and “a vision” is perfectly parallel. In B, “a critique” and “his envisioining”, and in C, “a critique” and “envisioning” are not parallel.
great!

这道题Ｇｉｇｉ女侠说ｍｅｔａｌ不是commodity。这么讲不好。小弟不才，蹭过MBA的宏观经济课和国际市场的课。商学的定义是，只要可以大量进行transaction,熟语非耐用品，具备fast moving consumer goods特点的商品都可以称作commodity。 课上一个ＮＹＵ的教授举例子的时候，甚至举到了钻石作为commodity的一种，因为de beer把其产业化，而且消费者也经常换首饰和报废首饰。这样的话，Ｄ应该是很好的选项。 Ｄ的ｒｅｍａｉｎ有没有ｓ阿，如果有的话，Ｄ比Ｃ好的
和尚鱼的题我突然看见Ａ里面的ｔｈｅｉｒ．．．．为哈阿。。。 这么说只有Ｃ了，可是Ｃ里面的ｗｈｉｃｈ很完蛋阿
我想吐了
其实金属期货交易里，commodities指均质金属的,选项C在这点上是没有问题的。
在LONGMAN Dictionary of Contemporary English里，
commodity:
1.a product that is bought and sold
2.a useful quality or thing
也许在国内的字典里忽略了1这样的解释，直接变成了“日用品”。
