8月1日,XM之战

本来8月1号就考完了。可是电脑坏了~~~只好等到今天再回馈CDer们~

备战期间CD给了我莫大的帮助,所以过了两天,我还是得上来发点JJ,否则我心里过意不去。在这里谢谢所有辛苦整理JJ的大牛小牛们!!!

还有,CD是让我觉得很人情味的地方,有那么多无私帮助别人的人。真心希望这种精神会一直传达下去,愿所有的人都能实现梦想,愿善者生存。

回到考试话题,从大牛小牛的理论角度来说,本人考得不好,610,M50V23。不过由于本人申请的国家对GMAT成绩并不是特别的严格,当当参考,所以610勉强算心满意足的目标了。真心恳请所有论坛上的牛牛们不要拍我~~

言归正传~

AWA

本人遇到了最普遍的那两题:

1、最好的老师是那些希望学生挑战传统观点的老师还是那些鼓励学生接受传统观点的老师

2、就是一间公司拓展业务开了一家貌似是修理的店之后销售额上升10%,于是他们就在计划里面打算要再开一家衣服店,杂货店,发展一站式服务,并说这样让他们在该区域的所有竞争对手中能够占有很大的优势。(不保证翻译全对哦,不过差不多就是这个意思了,理解下小妹的水平哈)

math:看见HANG13的呼唤了,所以特意浏览了一下JJ,看看有没有我要发布的JJ。很激动地发现,让我当头一棒的那个第一题,JJ没有。(终于有个为CDer们贡献的机会了)

题目是这样的,从A点到C点,可以有很多种走法,距离如图所示,如果不走回头路,A点到C点的距离,下列哪个是不可能的()(图我上传在附件里了。)

A 4x

B 4X+1

C 4X+2

D 4X+4

E 4X+5

PS.由于记忆的残缺性,确切的图我想不起来了,不过差不多跟我画的是一个类型,就是AC之间可以直达也可以吃饱撑着绕路走。而每段路的距离数据也是我编的(原谅我吧,实在记不得)。不过不影响这类题型的做法。答案的选项ABCDE是考试的真实选项了。当时看到这第一题我就愣住了,题目很绕不说,图也很纠结,不过后来静下心来分析也不过如此。最后的答案我选E。方法就是一条一条地找A点到C点的所有的路,共四条,然后把它们各自的距离算出来。如果GMAC没有换数据和图案,我确定是E

其他的题目,并且我还有印象的,伟大的JJ整理者们都已经悉数给出答案了。包括让我费解了3分多钟的JJ297题,我至今没弄明白这题到底想考我什么。

M考试部分给我的最大印象就是,差不多机经上面都能遇见一半左右,有很多的DS题类似于321题这种的,大家要严加防范

321 DS,a^2-b是不是大于0

1a-b大于0

2b大于0

E

V部分

看了一下阅读机经上没有我考过的一题,不过很惭愧很惭愧,这道题目好像是我的第四篇,我没有太多的时间去理解了,所以可能帮不了大家什么了。这篇挺长的,有一屏半。大意是讲科学家对于BLUE GRASS这种植物有个猜测或者假设,他们有春天生也有秋天生。然后他们的生长情况跟他们周边环境是不是拥挤有关系,太拥挤了当然不行,一定的拥挤程度可以促进生长。第二段就讲科学家做实验来验证猜测,还有春天生的和秋天生的两种品种的比较试验。(应该是这样吧~水平有限~时间有限~大家看看大概就好,到场上心里有个底,遇见了也不慌。)

题目我记得有一道是对整个第二段部分的高亮,问这部分起的是什么作用。我选的大概就是用实验证明他们的猜测啊什么什么的。(大家运用自己英明的判断力再自行理解吧!)

其它几篇阅读好像都是机经上面看到的,包括一篇全球变暖的SANDER学者反对前任观点提出的的南北半球各自变暖的原因啊什么的,一篇美国人和英国人的测量误差。还有一篇。原谅我吧,我还是记不起来了

阅读的感觉来说,不知道是不是进了低分题库的原因哦,反正我觉得有机经上的内容,熟记下来基本的框架和表述,上场之后,熟悉题目快很多,而且做题的时候很多障碍,比如说难解的单词啊什么的也会自动消除的。更重要的是,心里很有底很有底。

保佑所有辛苦的机经整理者能够万事如意。你们是好人啊~阿门~~

语法来说,我自己的感觉,也可能是进了低分题库的原因,有很多的平行结构题,还好,我其他不行,平行结构练得还是可以的,所以感觉语法做的比较轻松。具体题目想不起来了,只能表达下自己的感受。对了,现今的语法机经里面有几道被我碰上了,很幸运很感激~

逻辑来说吧,机经很有用,帮了一些忙。

有一道题目吧,说APE这种动物,濒临与某种疾病的危害,这种疾病据说是跟人接触传染上的,于是就有学者提出要建立什么人类止步区啊保护区啊什么的,反正就是隔绝人类与APE的接触。问削弱

有几个选项,我印象中的答案是,APE如果没有与人类接触就无法形成某某疾病的免疫系统,更容易引起死亡(充分由于自己成绩的不自信。大家看看就好,不要背我的答案)

还有一道,就是美国公司为员工提供了很多运动健身保健项目,好象是因为美国政府没有这方面的资金对国民进行补助。而加拿大政府有对国民设立一些促进大家健身的基金之类的,于是加拿大公司没有美国公司那样做的动机(这题的题干记忆很模糊,还是等其他战友继续补充吧)

好像差不多就是这些了,我能想到的为大家尽的绵薄之力也就只能到此为止了。各位还没考试的战友们,继续加油~~!!为了我们共同的梦想。

最后最后再次再次谢谢,隆重感谢,所有为大家整理机经的好心人们~好心会有好报的~~

好了,我的心愿已了,闪人~大家如果需要我的帮助的话,尽管留言哈~

一篇美国人和英国人的测量误差

请LZ确认是这篇原文么?

Every scientist knows about measurement bias, the systematic errors that can creep into data. A simplistic example would be a metal ruler that gives inaccurate readings when it expands in warmer temperatures.

Avoiding measurement bias can be impossible. Nobody’s perfect, after all, and neither is equipment. What’s important is recognizing bias and taking it into account when working with the data.

But it is not always easy to detect bias. A case in point is being reported in Nature, where researchers have uncovered measurement bias in six-decades-old data on global surface temperatures. The problem arises from how British and American ships measured the temperature of surface water.

David W. J. Thompson of Colorado State University and colleagues analyzed global mean surface temperatures from the 1880s to the present, tweaking the data to remove the effects of El Niño and other “weather noise,” as Dr. Thompson described it. They discovered a sudden drop of 0.5 degree Fahrenheit in 1945, but just in data collected at sea, not on land — a hint that the drop might have something to do with the measurements.

At that time, British and American ships did much of the logging of sea temperatures worldwide. On British ships, crews measured the temperature of seawater collected in a bucket水桶. But since about 1939, most American ships had switched to measuring the temperature of seawater as it was drawn through an intake pipe for use as an engine coolant冷冻剂,冷却液,散热剂. Because of heat from the engine room, American measurements were generally higher.

After looking more closely at the data, Dr. Thompson said, they realized what had happened. Most of the wartime战时 data came from American ships, with just 20 percent of the readings from British ones. But starting in August 1945, there was an abrupt switch. Nearly half the readings came from British ships. Because those readings are generally colder, Dr. Thompson said, that accounts for the sudden temperature drop.

Now that the bias has been recognized, climate researchers will need to take it into account in their models and simulations. But Dr. Thompson said the long-term trend, toward higher temperatures, would not be affected.

非常感谢LZ!

能回忆起题目么?试着回忆一下,谢啦!

我印象中关于measurement bias 的题目有一题就是关于美国和英国的测量误差的产生原因,下列不是的有哪些。这题比较有印象,没印象的应该就是一些比较常见的主旨题啊,结构题啊。反正我记得这篇我仗着有机经(我那时候还仅仅只是中文的缩略回忆版),就大概浏览了一些,把跟自己印象不一样的地方确认一下,然后就做题了,这样做我印象中做的还是比较顺的一篇阅读,更不用说还有机经的原文了。把全文理解通了就没问题了。

原文是在哪找的呀。。~  还有其他和rc JJ类似的文章吗。。
