1218晚场,回报CD~

潜水很久,从CD获益良多,虽然希望在GMAT成绩上能有所突破,但是非常无奈,三次尝试皆以710告终,无语...

本人脑子不好，考完记住不多，仅有的贡献出来。

AWA:

The following appeared in a presentation by the chief production manager of a machine parts manufacturing company at a management meeting:

“Our factory in Cookville is our most advanced and efficient. It is capable of producing ten drill bits for each dollar of production costs, whereas none of our other factories can produce more than seven drill bits per dollar of production costs. Therefore, we can reduce our overall drill bit production costs by devoting the Cookville factory entirely to drill bit production. Since reducing the production costs of individual machine parts is the only way to achieve our larger goal of reducing our overall production costs, dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.”

AI:

“Too many people think only about getting results. The key to success, however, is to focus on the specific task at hand and not to worry about results.”

语法
            

1. Far from doing…, XX…这个应该是考逻辑主语，选项中以人名开头的有两个，不确定答案

1. 海豚的声纳定位系统 JJ比较全，由于剩了没几分钟，没时间看了

2. 年轻的pulsar 和老的pulsar, 有个问Crab pulsar的特点；还有个问题到1%为了说明什么？

3. 维他命D, JJ非常全

4. Pioneer product and Pioneer market的重要性 JJ也很全，问了一道结构题

逻辑

1. 动物感染那个，不过A换了说法，说在动物园的人会从事多种职业

People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. Based on this sample, experts conclude that among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent but substantially more.

Which of the following, if true, provides the strongest grounds for the experts’ conclusion?支持

A.    A zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.  T

B.    A zoo employee is more likely than a person in the general population to keep one or more animal pets

C.    The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small.

D.    Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than exposure to many of the animals kept in zoos.   

E.     Zoo employees seldom wear protective gear when they handle animals in their care.

2. 要降低短期成本，降低员工的工资或减少工作小时数比开除他们来的好，因为裁员对任在岗的员工有负面影响，降低他们的生产力，好像是问评价吧，是说是不是减少工作小时也会影响士气     

3. 研究表明人们在回忆广告的时候，如果会比较容易记得广告的claim（理解为结论），而不容易记住广告的context。所以人们碰到相似的claim就会觉得是true，问能推出什么：

选的是人们不容易发现那些被证伪了的广告结论。

4. 有马可波罗来华那题

其它实在想不起来了，抱歉…

数学，重复一下JJ中出现的吧，记性实在不好

4个不相同的且大于２的整数的product is less than 500，then what is the possible greatest number among them? （8）

半圆里面套一个大正方形，旁边再套一个小正方形，问小正方形面积，圆半径是2根号5 （4）

一个部门，去年有部分人去参加某个活动，今年又要选一个去参加，问选到的人是上年参加活动的人的概率

(1)去年有百分之15的人参加

(2)这个部门有45人

JJ答案是A

240件衣服，问green且non-woolen的几件？

(1)green且woolen的件数

(2)non-green且non-woolen的件数

E

58. Monday Mary walking on a road for a certain mile at a average speed of 6miles/hour，Tuesday she trains on the road for a certain mile by bicycle at the speed of 15miles/hour. If in Tuesday the time Mary spent on the road is 16 minutes more than that on Monday, and the journey on Tuesday was 10 miles more than that of Monday. How many minutes did Mary spent on the road on Monday?

JJ主人说：“后面那个数不记得了
            反正也是简单运算”，注意单位换算

59. d是大于1的整数，1/d的百分位是3，千分位是7，问d-1/d的百分位是好多？

6

77. 8!/2!能够被2的N次方整除,问N最大值

我倾向于把上面的两个数字按照阶乘的定义展开..于是剩下8*7*6*5*4*3其中有2^6,于是N最大是6

97. 从40到50里（inclusive)的数，问这个数是几？

(1)被3除余2

(2)被4除余3

两个合起来看，47

考的是个变体，
        条件一在题目里，然后给的（1）说这个说是个奇数

111.10个小孩捐了28件衣服，每个人都捐了，range为2，问以下哪几个可能是捐了3件衣服的小孩人数？

I．0

II．5

III．9

I和III

150.
            N^35個位數是7 問N是甚麼的倍數?

是个变体，问N可能是以下哪个数，选个位是7的

156.
            X+Y=1, X^2+Y^2=3, 问XY最小等于几？

A. -3

B. -1

C. 0

D. 1

E. 3

我算了一个确定值-1

186.
            P是大于 t 的六个连续整数的和，n 是大于 t+6的六个连续整数的和，问N=？

鸡精主人说使用n表示的，那么p=6t+(1+2+3+4+5+6),n=6t+(7+8+9+10+11+12),表示一下就好

我的答案中是这样的：N=P+36

187.
            数集S 是负整数，consists of factors of 16, 数集T是负整数 consists of factor of 8, x belongs to S, y belongs toT，问the least possible vaule of x-y

同155题
            -15

188.
            ABC三个人，A做100个东西50小时，B做100个要60小时，C做100个要100小时，现在要做1000个，同时做要多少时间

214

208.
            8x+4y+5z=3，x,y,z均為正數，然后問x的值
                

(1)4y是整數

(2)5z是整數

要想x是正，那么8x就要正，那么3-4y-5z就要是正。而yz本身是正加上4y5z是整数，那么只能是4y=1，5z=1。于是x就是1/8

其它的：

27^x=1/81^y,用y表示x

问三角形的最大边

（1）给了一个角好像是50度

（2）给了另一个角是92度

我选的B

AB不等于0，问A/B的绝对值是不是=A/B

（1）AB的绝对值=AB

（2）A的绝对值/B的绝对值=A/B的绝对值

一个人2000年7月1日存了一笔钱，复利5%，按季算，问当时存了多少

（2）2001年7月1的利息大于一个数

JJ基本上给出了所有比较难的题，其它的都OK

从CD获取了很多，无以回报，仅能尽己微薄之力，祝所有CDer取得理想的成绩，申请顺利！！！

最新机经啊，哈哈

我已经在新世纪酒店了，这里有CMCC WLAN
