[转帖]1/8 JJ 加教训

我是1/8考的,700出头,M比较好,V比平常差了点,为什么会差,请看一下教训。如果你是第一次考Gmat, 请注意一下,不要犯我这种低级错误。。。

作文做完休息了一会儿我就进去了,估计是不到10分钟的,后来数学休息的时候我就想多休息,休息一会。考试人员是告诉我出来时间的,不过我心里总是想当然她们应该会提醒一下的,结果,进去后,她在电脑上输入密码的时候告诉我已经休息超时一分半了,于是我的V是从73:30开始往下做的。。。本来一分半也就是一道题的时间,不过当时对自己的心态真的是影响很大,前十题我是在无比郁闷和着急的状态下完成的,可想而知不会好到哪里去,而前十道题目的关键不说大家也是清楚的。所以,请要考试的朋友注意了:工作人员是不会提醒休息超时的,请一定算好提前量,不要犯我这种猪头错误!

另外,考试最后受到了一点影响,最后5题的时候,我左边的哥们咳得厉害,可能是感冒了,我后来感觉脑袋里只剩下了咳嗽声和自己的心跳,完全看不进题目,嘿,那位老兄,如果你看到这个帖子,可知我当时多想踹你一脚!当然,这个可不能怪他,谁能控制自己的咳嗽呢。不过有句话还是想说,如果哪位朋友咳的厉害去考试,可否让工作人员帮你调整一个离别人比较远的位置,里面有10台电脑呢,我想这样的话,对你没有影响,但同考的朋友会感谢你!

ok,进入正题,JJ:

1. AA

The following appeared as part of a plan proposed by an executive of the Easy Credit Company to the president:
“The Easy Credit Company would gain an advantage over competing credit card services if we were to donate a
portion of the proceeds from the use of our cards to a well-known environmental organization in exchange for the use
of its symbol or logo on our card. Since a recent poll shows that a large percentage of the public is concerned about
environmental issues, this policy would attract new customers, increase use among existing customers, and enable
us to charge interest rates that are higher than the lowest ones available.”
Discuss how well reasoned . . . etc.

2. AI

“As technologies and the demand for certain services change, many workers will lose their jobs. The responsibility for
those people to adjust to such change should belong to the individual worker, not to government or to business.”
Discuss the extent to which you agree or disagree with the opinion stated above. Support your position with specific
reasons and/or examples drawn from your reading, your observations, or your own experience.

Math:

1.DS: x,y正整数,问P^xy个位是不是1?

1)P^x 个位是1

2)P^y 个位是1

我选D

2. software 共有y种,computer game software 占15%(数字不确切), computer game software 中educational computer software占20%(数字不确切),问edu com software 占多少。

把两个比例乘一下就可以,注意把分数化成真分数才能对上答案,好像是6/25,不确定。。

3. list:S1, S2,...Sn, 问哪个条件list至少有一个是奇数?

1)忘了

2)ns等于多少来着,反正记住可以推出n,s乘积是奇数,那至少有一个是奇数的

刚想起来,2)list 的sum是奇数

4. 一条直线L1过(0, 7) (数字不确定,反正在y正半轴),还过一个点,在X负半轴,L2和它相交吗?

1) 给一个L2方程, 是可以推出相交的,好像是y=(-3/5)x+6

2) L2 的斜率是-3/5

这道题应该是D

5. 圆形和正方形面积相等,问周长比是多少?圆/正方形

即:(Pai)R^2=a^2

求2(pai)R/4a, 代入可得解

6. 有一道关于方差的DS题,问最大的数会是多少。题目记不得了,不过提醒大家把标准方差的公式背一下,看到了这题的话不要被吓倒,把公式列出来,average用一个字母代,最后可以得到一个结果是(s1-A)^2+(s2-A)^2+...+(sn-A)^2=0,于是可得sn是多少,题目会告诉s1为10。

想起来了,题目是问sn是多少?

1)s1=10

2)standard deviation=0

7. 有道题目很怪,我估计是测试的题目:[x]为x的大于等于x的最小整数,问下面哪个选项符合[x]=0?是must be true

选项有A.x=0, 另外四个是不等式,bcd很好排除,e是-1<x<=0,我感觉A和E都是成立的,但因为是must be true, 而e成立的话a必然成立,所以想了半天还是选了A

8. 后面有道题,某个人每个月take home 的money 20%用在什么上面了,剩下中的30%用在了B上面,他take home 了2000元,问有多少钱用在B上面

我做出来是480

最后的一题是:x^2+2x-5=y^2-5y+7 (数字皆不确定,不过这是二元二次方程),问以下关于Y哪个选项must be true?

A. y is not negative number

B. y is even number

c.

具体选项无法回忆,但是最后可推出x(x+1)=y^2-6,所以Y必然是even number

如果时间来不及的话,就选even那个选项,因为我数学满分,所以还是比较有把握的。

另外一道DS题,在刚开始的时候出现,是比较简单的。

问以下x的值是多少?

1) x^2+x-6=0 (可能是这个方程,最终能得出x=2 or x=-3)

2) x^4=16

选C

SC 遇到一题:

Marconi’s conception of the radio was as a substitute for the telephone, a tool for private conversation; instead, it is precisely the opposite, a tool for communicating with a large, public audience.c

 

 

 

  1. Marconi’s conception of the radio was as a substitute for the telephone, a tool for private conversation; instead, it is

  2. Marconi conceived of the radio as a substitute for the telephone, a tool for private conversation, but which is

  3. Marconi conceived of the radio as a tool for private conversation that could substitute for the telephone; instead, it has become

  4. Marconi conceived of the radio to be a tool for private conversation, a substitute for the telephone, which has become

  5. Marconi conceived of the radio to be a substitute for the telephone, a tool for private conversation, other than what it is,

verbal部分我做的不太好,记性实在是差,所以就不写自己不确定的了,以免误导群众
