下午场少量几经

 

 

 

79²
   等于多少，我选
   80²-80-79

 

 

 

原题有图，有个4边形ABCD，DA=AB=BC=10，A角90度，B角135度，求面积，选项为
   50，40，100，50√2，50（1+√2），能分成2个直角3角形，简单

 

 

 

有XY plane上已知2点（-1，0），（5，0），问
  点Q（X，7）为多少使组成等边3角形

 

 

 

DS题，学英/法/西三门语言，共49个学生，学法的26人，西或西和法都学的37个，两个选项1 都不学的有xx（具体数字忘了），2 学西和英的有多少，问能否求出光学西文的。

貌似不行，俺们选了E

 

 

 

其他的都基本是重复的几经了。有DS题，关于2天生产625件，500件以内如何计价，500件以上如何计价的，第2个选项改成每天都不低于140，不影响结果，还是B

 

 

 

AA：某汽车制造公司的HR说据研究表明非盈利性机构的员工的生产效率比较高，因为他们知道自己的工作对社会有贡献，被motivated了，所以他们公司也应该大量捐钱，才能激励员工，提高生产效率，进而提高效益。

AI 员工是否应将私生活和工作场所分得越开越好

 

 

 

RC

第一题

P1 IT行业，开始时硬件的发展缓慢限制了行业发展，到1980-1985年，硬件大发展，价格下降，因计算机utilization上升，销量上升，总利润和销售上升
  （有题），P2 90年后硬件过度发展，但utilization到顶了，销售额下降，利润下降。P3 提出观点，计算机公司应弥补技术和应用之间的gap （有题）
   P4 举了2个公司做例子，I弥补了gap，II技术先进
  （有题），市场份额却小，因为软件只能应用于自己生产的电脑，I却能广泛应用。II要改进应用

 

 

 

第二题

黑洞无法观测到，因此需要用其他可见的物体的变化来判断。接下去主要讨论观察到的现象到底是A cluster of Stars的重力造成的，还是黑洞造成的，举了2个例子

 

 

 

第三题

服务业在东南亚国家的发展及和第一第二产业的关系

 

 

 

几经先到这，其他的想起来再补

再说些复习的心得吧 （都是老调重弹，俺们老了，太罗嗦，请大家包涵！） V41 M50 /750

1。知己知彼百战不殆

用模考知己，用CD几经知彼，知己：一定要分析自己的弱项，针对性的提高，知彼，一定要反复感觉ETS的出题思路和考点，不一定要题海战术，俺们除了模考软件做了4次，OG看了一遍之外，其他的都是看了2眼就放弃了的。俺们的感觉是不管是SC/CR还是RC，关键先是看懂题意，领悟美国佬的逻辑！即使是SC，句子的逻辑点还是高于语法点! 今天就碰上SC一题2个选项都没什么语法错误，关键选择还是是逻辑意思是否正确。故而复习语法的时候不要拘泥语法，还是要从句子的整体意思选择合适的语法。当心太注重细节反而忽略整体！

2。休息是为了走更长的路

我是周三下午考的，从上周六开始到昨天，连续4天，俺们每天睡到自然醒，因为自己是夜猫子，只有晚上复得进，且考试时间为下午，故而放弃早上的时间。CDer，请注意身体，注意休息！合理膳食，哈哈。。。。。。

3。心态很重要

因为我要参加的是公司赞助online mba 项目，分数要求不高，故而我对自己要求也不高，T我只要80，G 650，结果都超额完成任务。 考试时保持平静的心态很难，但是很重要。偶尔迷信下会有很大帮助哦！我考试开始前祷告了下，请各路神仙，包括古今中外的，都帮忙下。即使过路神仙没帮上忙，祷告也有助于我集中精神，平复心情。出门前还查了星座网站，发现今天的幸运色是白色，故而除了牛仔裤外，其他服饰配件一律白色！幸运色果然幸运！上次考T的时候也是穿着幸运色去的，呵呵！

下面要发表感言了，米兴趣的请退场，谢谢！

在接过unofficial report的时候，俺们的感觉就像是接到了小金人，最想的就是说谢谢，谢谢CD，没有这里，我根本不可能完成这个不可能的任务。考G我只有2周的复习时间，其间还出国1周，考T更是只有10天的上班时间而且还出了2天差。俺们这种离开学校10年之久的老菜鸟，突然被公司逼着来考试，米有CD怎么办啊。

最后，祝大家都能考出理想的成绩！

       第二个阅读是这个不？

黑洞存在的研究

Astronomers theorize that a black

       hole forms when a massive object

       shrinks catastrophically under its own

Line gravity, leaving only a gravitational

  (5)field so strong that nothing escapes it.

Astronomers must infer the existence

of black holes, which are invisible,

from their gravitational influence on

the visible bodies surrounding them.

 (10)For example, observations indicate

that gas clouds in galaxy M87 are

whirling unusually fast about the gal-

axy’s center.  Most astronomers

believe that the large concentration

 (15)of mass at the galaxy’s center is a

black hole whose gravity is causing

the gas to whirl.  A few skeptics have

argued that the concentration of mass

necessary to explain the speed of the

 (20)whirling gas is not necessarily a black

        hole:  the concentration in M87 might

        be a cluster of a billion or so dim stars.

  The same hypothesis might have

been applied to the galaxy NGC 4258,

 (25)but the notion of such a cluster’s

existing in NGC 4258 was severely

undermined when astronomers mea-

sured the speed of a ring of dust and

gas rotating close to the galaxy’s

 (30)center.  From its speed, they calcu-

lated that the core’s density is more

than 40 times the density estimated

       for any other galaxy.  If the center of

NGC 4258 were a star cluster, the

 (35)stars would be so closely spaced

that collisions between individual

stars would have long ago torn the

cluster apart.

 

--------------------------------------------------------------------------------

Q10:

The skeptics mentioned in the first paragraph would be most likely to agree with the astronomers mentioned in line 13 about which of the following statements concerning the galaxy M87?

1. The speed of the gas whirling around the center of M87 is caused by a dense object that is not a black hole.
2. The concentration of mass at the center of M87 is probably a large cluster of dim stars.
3. The presence of a black hole at the center of M87 is the most likely explanation for the speed of the gas whirling about the galaxy’s core.
4. The speed of the gas whirling around the center of M87 is caused by a large concentration of mass at the core of M87.

5. The gravitational influence of a star cluster would not be strong enough to account for the speed of the gas whirling around the core of M87.

 

--------------------------------------------------------------------------------

Q11:

The passage asserts which of the following about the existence of black holes?

             

1. Astronomers first speculated about the existence of black holes when they observed gas whirling around the center of a particular galaxy.
2. Evidence used to argue for the existence of black holes is indirect, coming from their presumed effects on other astronomical bodies.

3. Recent observations of certain astronomical bodies have offered proof.
4. A considerable body of evidence suggests the existence of black holes, even though their behavior is not completely consistent with the laws of physics.
5. Many astronomers are skeptical about certain recent evidence that has been used to argue for the existence of black holes.

--------------------------------------------------------------------------------

Q12:

Which of the following, if true, would most clearly undermine the possible explanation for the whirling gas in M87 that is mentioned in the last sentence of the first paragraph?

             

1. The stars in a star cluster at the center of M87 could exert a strong gravitational force without tearing the cluster apart.
2. A cluster of stars at the center would preclude the existence of certain other astronomical phenomena that have been observed at the center of M87.
3. The stars within many existing galaxies, such as NGC 4258, are more closely spaced than are the stars within the core of M87.
4. Only one other galaxy has been observed to contain gas clouds whirling about its center as they do about the core of M87.
5. The gravitational force of a cluster of a billion or so dim stars would be sufficient to cause a whirling ring of gas and dust to collect around the center of a galaxy.

没错，就是5楼的这篇黑洞，不过题目有两个Q10/12一样，另一个好像不一样
