我是10月31日大连的,640,M50,V27
心情不平静,写得相当乱。
先说点儿感受:
感受就是分出来的那一刻,我都感觉这是纯在搞笑。
我考前五天头一次用GMATPREP,根本不熟悉界面,V到二十多题就全是乱选的,结果都是V28,650。考前一天绝对不受一点儿干扰地,用GMATPREP模了一次,里面一道见过的都没有,我还V40,750(这个分让我对实战相当有信心)。而且实战中我的V有不少JJ,怎么想也不明白,怎么可能这个分,怎么可能比我第一次用PREP胡答还低。
因此恳请高手指点!!!这是怎么回事儿呢?
当我平静一些,我想,导致我V这次这么差的一个主要原因,可能是我做V的时候太放松了吧。因为遇到的4篇RC全是JJ(下面会说到)!可能一兴奋,心理大受影响。可能除了RC对的就很少了。
而且RC中有些题和JJ题干很像,但选项略有出入。我做的时候又想JJ,又想自己做,最后……可能做得还是错的。
还有,当时做了两道全划线的SC,心里还很兴奋,心想肯定分不能低了。看来,切不可把全划线的SC的一概当成高分的表现!!!而且现在想想,那些划线长的,其实也不太难,用单复数、逻辑主语、平行就可以做出来……(不过也可能是我把题想简单了?要不分怎么这么低?真的是不知道怎么才这个分……)
JJ:
M:记得不多了,我从小到大,都不太记得考题
JJ其实可以看18号换题后的就可以了,里面能遇到不少。不要有什么负担。
说说好像没有的(因为我也没有把18号后的都看全)。
1.X和Y两城市有A(记不住了,先用字母代)和B(这个记住了,是核发电)两种发电方式。X用A发的电是Y用A发的电的3倍,而两城市用B发电的量一样。知道用X用B发的电占X总数的百分数是K,求Y用B发的电占Y总数的百分数?
(!!!加亮部分我也不确定了,反正说的是类似的数量关系,因为我最后没算出答案的数,可能是我看错了,我随便蒙了一个!!!)
选项有K、(2/3)*K什么的……
2.DS:X^2-Y^2是否为0.
(1)x+y=2x (2)x-y=0
我选了D,我记得是因为差点选了B
3.求(9.86673945739857)(10^9)/(10^3)
具体数记不住了。反正那个小数是可以当成10约算的。
很简单,大家肯定会做。选项都是10的多少次方,不迷惑人。
别的一时也想不起来了。想到会还来这里补的。不过大家对M真要有信心,看看已经整理的JJ就够了。在此感谢整理JJ对CDer!!!
另外,像两个集合各含多少元素的题一定要会做。大概就是一个班共多少人,学A语的有多少人,学B语的有多少人,什么都不学的有多少人,只学A不学B的多少,只学B不学A的多少……这种题。JJ里都有,看看一道就可以全搞定了。
个人认为数学还是简单的。
RC:
真的是晕了。4篇全是JJ,怎么分还这么低。所以,我想这个JJ的用法还真得把握好。到考场上可能最怕的就是我这样,JJ有说,但说得不细;或说得有误;或选项有真题不一致。那时候,又想自己做,又想JJ的状态其实真的不好。
1. JJ汇总里的第37篇,merger和acquisition的题,就是企业兼并分析的。
这一篇真要再感谢JJ的提供者和整理者!29日的JJ里还没有,30日的JJ就有了,我考前一天晚上看的,应该全对了吧。都是原题!(妈的,又不理解了,怎么可能得这么少的分……)
这题我就不贴了,在18号换题后的RC汇总里有,是37篇,
30日才更新的。这是GWD原题。大家好好看看
2.JJ汇总里的第21篇,拉丁文学那篇。
这篇我不多说了,因为这篇我可能有错的,所以不误导大家。JJ里的背景是没错的。大家看看,了解一下背景,做的时候我建议还是自己做一下。
千万不要记这一篇JJ里说的问题和答案,因为我记得JJ里的人说得不对。
3.JJ汇总里的第22篇,耳部肌肉的那一篇
这一篇的JJ比较全,问题、答案也好像整理得不错。值得看!
我还是觉得都做对了啊。妈的……那分怎么那么低?难道我真除了RC别的没对几个?
4.JJ汇总里的第30篇,Jupiter的卫星的
这篇的JJ不全,只能当背景,做还要自己做。
这是我的第一篇。感觉做得不好,而且现在回忆,也只回忆原JJ有的那些内容,再加上才得这么点儿分……不误导大家了吧。
……
5.怪了。
只有4篇阅读,还是可能有5篇……我怎么还回忆起一篇?我真的记得是今天上午做过的啊。
可能解释只有两个:1.这篇和卫星那篇是一个,我弄错了。2.纯是幻觉,把以前的题当成今天做的了(但不可能记得这么清楚吧)……
这太恐怖了吧……
不管了,先说出来吧。版主和NN要查查以前的JJ啊,看我到底是怎么的了……
是关于流星还是流星雨(反正是个的和流星有关的东西,我也不知道是不是流星雨),讨论的是其成因。
介绍了解释流星雨形成的理论。说流星雨是像个管子,中间是空的。
又说还有种理论说是越到中间密度越大,正好相反。
后面说了些现象。
其中有问到,两种理论都认同哪一点,还有题问到流星雨经过地球时候会有什么现象(这一问文中有说)
RC遇到那么多JJ,怎么V也做得不好???
还TMD回忆成了五篇RC,我晕……真不知道是怎么回事。
CR没有遇到JJ。
CR我真不敢回忆了,大家看到了我的记忆力了吧,我回忆CR你们敢看吗?确定地想到了再来补充吧。
AA:
95. The following appeared as part of an article in the business section of a local newspaper.
“Hippocrene Plumbing Supply recently opened a wholesale outlet in the location once occupied by the Cumquat Café Restaurant. Hippocrene has apparently been quite successful there because it is planning to open a large outlet in a nearby city. But the Cumquat Café, one year after moving to its new location, has seen its volume of business drop somewhat from the previous year’s. Clearly, the former site is a better business location, and the Cumquat Café has made a mistake in moving to its new address.”

这个AWA应该没错。
总之:
我是TMD晕了,现在什么都不明白了。没给大家提供好JJ
抖胆提几点建议:
1.RC的JJ,要记只记那些版本很全的,或是OG、GWD的原题。那些版本不全的,只能看看当背景,考试还要自己做。(我回忆的RC你更别记了……)
2.MATH的JJ汇总就够了。不用有负担。
3.全划线的SC可不是高分题的标致!别太早兴奋!
4.遇到再多的JJ也别兴奋!别向我这样……
另外还要再次地诚挚地向整理JJ的几位致谢! 真的是用了这些JJ,才知道这几位CDer的贡献! 大家都要好好感谢他们!!!
另外还要再次地诚挚地向整理JJ的几位致谢!
真的是用了这些JJ,才知道这几位CDer的贡献!
大家都要好好感谢他们!!!
NN们能不能过来解释一下啊:
我这个RC回忆得是怎么回事儿?
RC绝对不要看JJ,自己做!能做多少是多少,能看多少是多少~
真得多谢楼主了,我马上就要考了,现在看了这么多JJ弄得整个人都好像很轻松那样想着考试就靠JJ吧,你这一提醒还真把我吓着了。。。我做GWD时遇到见过的题都会直接点答案过去了,看来还真不能这样~~!
总之谢谢楼主提醒了,祝顺利!
謝謝樓主,繼續加油!
(樓主很幽默的說)
看来我不得不过来冒个脸了。
首先,感谢你回忆了5篇RC JJ。
然后,感谢你写了这么多以后提醒不要用你的JJ(当时一滴汗啊。。)
再次,我厚脸皮接受你的感谢。
哈哈哈……
咱继续加油!我二战都失败了呢,怕啥,明年再来!
真诚感谢上面各位的祝愿!也祝你们有好的成绩!!!
大家提的建议,我都记下了,我已经报了12月12日的考试,坚决二战了。
我真的考前一天还GMATPREP得了750呢(大家也知道啊,做模考时有时间限制,也不可能去作弊,那里的题我还都没见过;如果说与实战不一样,我觉得最主要的还是心态不一样……),真没想到怎么实战会差100多分……所以绝对要二战!
关于JJ,大家真的是可以利用,但不能全依赖啊……
再次感谢大家,大家一起加油!!!
哎,哥们儿,你说得没错!感谢!!!
我看了,果然是这一篇!
我就帖一下啦:)这是从OG10WORD版里粘的。
A meteor stream is composed of dust particles that have been ejected from a parent comet at a variety of velocities. These particles follow the same orbit as the parent comet, but due to their differeing velocities they slowly gain on or fall behind the disintegrating comet until a shroud of dust surrounds the entire cometary orbit.
Astronomers have hypothesized that a meteor stream should broaden with time as the dust particles’ individual orbits are perturbed by planetary gravitational fields. A recent computer-modeling experimetn tested this hypothesis by tracking the influence of planetary gravitation over a projected 5,000-year period on the positions of a group of hypothetical dust particles. In the model, the particles were randomly distributed throughout a computer simulation of the orbit of an actual meteor stream, the Geminid. The researcher found, as expected,
that the computer-model stream broadened with time. Coventional theories, however, predicted that the distribution of particles would be increaingly dense toward the center of a meteor stream. Surpringly, the computer-model meteor stream gradually came to resemble a thick-walled, hollow pipe.
Whenever the Earth passes through a meteor stream, a meteor shower occurs. Moving at a little over 1,500,000 miles per day around its orbit, the Earth would take, on average, just over a day to cross the hollow, computer-model Geminid stream if the stream were 5,000 years old. Two brief periods of peak meteor activity during the shower would be observed, one as the Earth entered the thick-walled “pipe” and one as it exited.
There is no reason why the Earth should always pass through the stream’s exact center, so the time interval between the two bursts of activity would vary from one year to the next.
Has the predicted twin-peaked activity been observed for the actual yearly GEminid meteor shower? The Geminid data between 1970 and 1979 show just such a bifurcation, a secondary burst of meteor activity being clearly visible at an average of 19 hourse (1,200,000 miles) after the first burst. The time intervals between the bursts suggest the actual Geminid stream is about 3,000 years old.
80. The primary focus of the passage is on which of the following?
(A) Comparing two scientific theories and contrasting the predictions that each would make concerning a natural phenomenon
(B) Describing a new theoretical model and noting that it explains the nature of observations made of a particular natural phenomenon

(B) Meteor streams grow as dust particles are attracted by the gravitational fields of comets.
(C) Meteor streams are composed of dust particles derived from comets.
(D) Comets may be composed of several kinds of materials, while meteor streams consitst only of large dust particles.

(C) explore the nature of a particularly interesting meteor stream
(D) test the hypothesis that meteor streams become broader as they age
(E) show that a computer model could help in explaining actual astronomical data
83. It can be inferred from the passage that which of the following would most probably be observed during the Earth’s passage through a meteor stream if the conventional theories mentioned in line 18 were
(A) Meteor activity would gradually increase to a single, intense peak, and then gradually decline.
(B) Meteor activity would be steady throughout the period of the meteor shower.
(C) Meteor activity would rise to a peak at the beginning and at the end of the meteor shower.
(D) Random bursts of very high meteor activity would be interspersed with periods of very little activity.
(E) In years in which the Earth passed through only the outer areas of a meteor stream, meteor activity would be absent.
84. According to the passage, why do the dust particles in a meteor stream eventually surround a comet’s orginla orbit?
(A) They are ejected by the comet at differing velocities.
(B) Their orbits are uncontrolled by planetary gravitational fields.
(C) They become part of the meteor stream at different times.
(D) Their velocity slows over time.
(E) Their ejection velocity is slower than that of the comet.
85. The passage suggests that which of the following is a prediction concerning meteor streams that can be derived from both the conventional theories mentioned in line 18 and the new computer-derived theory?
(A) Dust particles in a meteor stream will usually be distributed evenly throughout any cross section of the steam.
(B) The orbits of most meteor streams should cross the orbit of the Earth at some point and give rise to a meteor shower.
(C) Over time the distribution of dust in a meteor stream will usually become denser at the outside edges of the stream than at the center.
(D) Meteor showers caused by older by older meteor streams should be, on average, longer in duration than those caused by very young meteor streams.
(E) The individual dust particles in older meteor streams should be, on average, smaller than those that compose younger meteor streams.
86. It can be inferred from the last paragraph of the passage that which of the following must be true of the Earth as it orbits the Sun?
(A) Most meteor streams it encounters are more than 2,000 years old.
(B) When passing through a meteor stream, it usually passes near to the stream’s center.
(C) It crosses the Geminid meteor stream once every year.
(D) It usually takes over a day to cross the actual Geminid meteor stream.

(E) The computer-model Geminid meteor stream provides an accurate representation of the development of the actual Geminid stream.
-------------------
80.
This question asks you to identify the primary focus of the passage.
The best answer is B. The author describes the new theoretical model in the first paragraph; in the
final paragraph the author states that the data obtained from actual observations, which are
discussed in the second and third paragraphs, is consistent with the new theoretical model.
Choice A is not correct; the computer model confirmed the astronomers’ hypothesis that meteor
streams broaden with time, and although the model yielded an unexpected result, the passage does
not contrast the predictions yielded by competing theories. Choice C and D are not correct because
the passage makes no reference to further areas for research, and only a single phenomenon is
described in the passage. And choice E is not correct because it reverses the order of events. The
model yielded a prediction that was subsequently confirmed by observational data, the model was
not constructed to explain the data.
81.
This question asks you to identify an accurate statement about meteor streams. Choice C, the best
answer, restates information about the composition of meteor streams from the first sentence of
the passage.
Choice A is not correct. The passage discusses the influence of planetary gravitation on meteor
streams but says nothing about its influence on the orbits of comets. According to the passage, it is
planetary gravitation, not the gravitational fields of comets, that causes meteor streams to increase
in size, so choice B is not correct. And choice D and E are not correct answers because the passage
says nothing about the composition of comets or the role that meteor streams play in their further
disintegration.
82.
This question asks what the author says about the purpose of the research described in the first
paragraph.
The best answer is D. According to the author, the purpose of the computer-modeling experiment
was to test the hypothesis that meteor streams broaden with time.
Choice A is not correct; although the observational data described in the last paragraph allowed
scientists to estimate the age of the Geminid stream, this data was analyzed to confirm a surprising
prediction made by the computer model. This analysis was not part of the original experiment.
Choice B is also incorrect. Although the experiment yielded a surprising prediction about a
particular feature of meteor streams, the purpose of the experiment was to determine whether
meteor streams broaden with time, not to identify the various structural features of meteor streams.
Choice C is not correct because the experiment was undertaken to test a general hypothesis about
meteor streams. It was not undertaken to explore the nature of any particular meteor stream, and
328
the passage never suggests that the actual meteor streams used in the computer model was
“particularly interesting.”
Choice E is not correct. Although the computer model did confirm the astronomers’ hypothesis,
the purpose of the experiment was not to show that such models are useful.
83.
This question asks you to make an inference about what would most probably be observed during
the Earth’s passage through a meteor stream if the conventional theories mentioned in the passage
were correct. According to line 18-20, the conventional theories predicted that the meteor stream
would be most dense at the center. The computer model, one the other hand, predicted that a
meteor stream would come to resemble a thick-walled, hollow pipe (lines 21-22). The passage
states that, if the computer model were correct, two peak periods of meteor activity would be
observed as the Earth passed through the walls of the “pipe” (lines 28-31). According to lines
36-38, observational data confirmed the prediction of the computer model. If, on the other hand,
the conventional theories were correct, it can be inferred that a bifurcation of meteor activity
would not be observed; instead, it can be inferred that scientists would expect to observe a single
peak of meteor activity as the Earth passed through the dense center of the stream. Choice A
identifies this single peak of activity as the most likely observation if the conventional theories
were correct.
Choice B and D are not correct because they describe meteor activity that is either steady or
erratic, neither of which is consistent with the conventional theories. Choice C describes meteor
activity more in line with the bifurcation predicted by the computer model, rather than the single
peak of activity that the conventional theories would suggest. Choice E is incorrect because the
passage says that meteor showers occur whenever the Earth passes through a meteor stream; it
cannot be inferred that either theory would predict otherwise.
84.
This question asks for the reason given in the passage for a characteristic feature of meteor
streams. According to lines 1-7, the dust particles in a meteor stream eventually surround a
comet’s original orbit because of the different velocities at which they are ejected, as stated in
choice A, the best answer.
Choice B is directly contradicted by information in the passage (lines 8-10). The other answer
choices re incorrect because the passage does not say that the dust particles become part of the
meteor stream at different times, or that their velocity slows over time, or that their ejection
velocity is slower than that of the comet.
85.
This question asks you to identify a prediction that can be derived from both the conventional
theories about meteor streams and the new computer-derived model. You must base your answer
on information that is suggested by, but not expressly stated in, the passage.
According to lines 7-8 of the passage, the conventional theories hypothesized that meteor streams
should broaden with time, and the computer simulation confirmed this hypothesis. The passage
also suggests that the time it takes for the Earth to cross a meteor stream (and, by implication, the
duration of the resulting meteor shower) is directly related to the breadth of the stream (lines
23-28). From these pieces of information, which are supported by both the conventional theories
329
and the new computer-derived theory, it can be inferred that on average the meteor showers
caused by older (and therefore broader) meteor streams would be longer in duration than those
caused by very young (and therefore narrower) meteor streams, as stated in D, the best answer.
Choice A is incorrect because it contradicts the predictions of both the conventional theories (that
the particles will be most dense at the center of the stream) and the computer model (that the
stream will resemble a thick-walled, hollow pipe). Choice C is also incorrect because it is
inconsistent with the conventional theories that suggested the distribution of dust in a meteor
stream is denser at the center. And choices B and E are incorrect because the theories discussed in
the passage do not suggest anything about the likelihood that the Earth’s orbit will cross that of
any particular meteor stream, nor do they suggest anything about the size of the dust particles that
compose meteor streams.
86.
This question asks you to draw an inference from information in the last paragraph of the passage.
The best answer is C. According to the passage, the Geminid meteor shower occurs yearly;
because meteor showers occur whenever the Earth passes through a meteor stream, one can infer
that the Earth crosses the Geminid stream once every year.
Choice A is incorrect because the passage provides no information from which to generalize about
the age of meteor streams. Choice B, which is directly contradicted by lines 31-32, is also
incorrect. Choice D is incorrect. In lines 25-28, the passage says that the Earth would take just
over a day to cross the stream if the stream were 5,000 years old. However, in lines 38-42 the
passage states that in fact an average of only 19 houses elapsed between the time that the Earth
entered the stream until the time that it exited, leading researchers to conclude that the stream is
only about 3,000 years old. Choice E is incorrect because the passage says only that planetary
gravitational fields perturb the orbits of dust particles in a meteor stream; it does not say that the
effect of the Earth’s gravitation is greater than that of other planets.
87.
This question asks you to identify an assumption underlying the last sentence of the passage. In
this sentence, the author of the passage draws a conclusion about the age of the Geminid stream.
This conclusion is based on two pieces of information. The first is the length of time the Earth
would take to cross the computer-model Geminid stream if the stream were 5,000 years old (lines
24-28). The second is the actual elapsed time between the two peaks of meteor activity predicted
by the computer model (lines 36-40). In concluding from this information that the Geminid stream
is actually only 3,000 years old, the author is assuming the accuracy of the computer model, as
stated in E, the best answer.
Choice A is incorrect because the passage says that the time the Earth takes to cross the stream
would vary from year to year (lines 32-34) and that 19 hours was the average time, not the exact
time, observed from 1970 to 1979 (lines 36-40). Choices B and C are incorrect because the
passage does not suggest anything about the current state of the comet associated with the
Geminid stream or about the expected longevity of the stream. Choices D is incorrect because the
computer model is said to confirm the broadening predicted by the conventional theories; the fact
that the model projected the positions of the particles in the stream over a 5,000-year period does
not suggest that researchers expected the stream to be older (and therefore broader) than it turned
out to be.

感谢这位哥们儿!
这个在置顶帖里应该有吧。
我记得我看到里面是说,会把五年内的考试成绩都寄过去。不知道有没有错。
不过我想,这没什么关系,我们好好考就行了。
好好复习,越考越好,让老外看到我们的上升趋势可能也没什么不好。
况且,GMAT又不是唯一一个考查标准。你的学术水平、推荐信、工作经历什么的我感觉可能都比GMAT重要吧。
但话又说回来了,如果是不好好复习,考得成绩都不好,又波动比较大,那就不太好了……
是吗?哦……
不过,我那天做GMATPREP得750那次,V是前三题没错,4到6题连错三道。但分数也还可以啊……
也许是我实战时候,整体都做得很不好吧。
嗨……可是压根没有感觉啊。还见了两道SC全划线……以为分肯定不低了……
MMD搞笑……
謝謝樓主,繼續加油!
(樓主很幽默的說)
还幽默哩……
我边写都边泪血……
XD,你真的粉幽默,尤其看见你的头像,实在忍俊不禁!(哎哟,一不小心成了没有同理心的坏人——人家伤心着流下血泪了啦,偶还在笑,自动罚跪,楼主不要伤心)
然后,请问XD,到底这个OG的“第5篇”是你的幻觉还是真的考了呀?(心想是幻觉吧)
看来我不得不过来冒个脸了。
首先,感谢你回忆了5篇RC JJ。
然后,感谢你写了这么多以后提醒不要用你的JJ(当时一滴汗啊。。)
再次,我厚脸皮接受你的感谢。
哈哈哈……
咱继续加油!我二战都失败了呢,怕啥,明年再来!
MM整理JJ工作辛苦造福后人,些许感谢当之无愧。
我们都加油啦!!!
P.S.Evonne这名字挺有不错,不过我只记得《珍珠港》里女主角名字叫这个,还有许慧欣名字叫这个,不知道有没有联系……:)
我们也在犹豫是否要报12号的考试呢,如果抱了,到时候会再次碰到了。
那天有个男的一直在隔壁等着,就是我了。
我看到了那天的8个人全部考试成绩,都不太好,最高才690,可惜MATH分数还不高,好像47还是49,再高点就过700了,真遗憾。
和大外那个监考老师,白胖男的,挺好说话的,聊了一会,才知道他是我妻子的学弟,所以我可以他的监控计算机上看你们考试。 :) 赫赫。

咦?“那天有个男的一直在隔壁等着,就是我了。”什么意思哈?考试的怎么还一直在隔壁等?
我只记得那天有个男生是父母陪着来的,因为他好像受了伤,还拄着拐。
呵呵,反正我报了12月12号的了,到时候见。我1.6米左右一个小男生:)
加油吧
我的水平不高,受益匪浅啊
现在我终于知道了,所谓的第五篇RC实际就是OG的原文,那是我在考前一天做PREP时遇到的!
汗!!!
耽误了大家这么久!!!
巨汗!!!
