[转帖]2006.01.05-刚考得几经 想到一道数学题(1月8日),(1月9号)再加几道数学题


刚刚考得(北美),现在的题目变化真的很大,而且草稿纸时塑料的,另外阅读没有行号,考得不好,但是还是发机井把:

issue:

Responsibility of preserving the natural environment ultimately belongs to individual person, not to goverment

aa:

In P district, A theatre, B Pizza and C golf club have had increase their sales last year. So the Capital Idea want to invest to three business theatre, E Pizza ,F Golf Club. It want to give the discount to the custormers who already patronize two of three business. He argue such discount will maximize the sales.

数学的题目很怪,我时间刚刚好够,记得有一提是这样样的

t-5-9-7-8

e-f-2- -1

6-3-3

3-0

3

the structure is right, not the figure.Every figure is equal to the nearest two figure in the line above with the right one sbustracted from the left( 每个数字等于靠他最近的上一个行左边的数字减去右边的数字),题目很长,我看了半天才看出来。

还有一体是这样的:

There is one survey testing 60 people who taste the three different flavor icecream : V(allina), C(hocolate) and S(trawberry). All the people do the survey and rank them , there are no situation that two flavor rank equally, 3/5 of people rank V worst. 1/10 of them( 我觉得这里还是60 rank v ahead of C ,1/3 of them rank v ahead of s, ? how many people rank v first?

还有一体问 median (图标题)

number of people donation

10 $100,000

10 $50,000

70 $10,000

60 $25,000

50 $5,00

还有几道题也挺烦得。我平常作都是提前15分钟,今天居然刚好够。

语文朝郁闷:第一体就没把握,看了足有两分钟,记得

有一题 选项有.... the child emotions---- , v....

,b not only of those that are good., but also those that are bad,

d regardless of good or bad,

阅读没有行号,虽然有highlight,但是 很少,所以细节体不好对应:

black people:

第一段,。。的作用不仅在于提高工资,还在于产生了一个黑人中产阶级。(有题)

one person doen not concertrate on the " Great Immigration" but on pro(一个单词)(有题,时间对应),before the first world war(1914), .....1914-1925(Great Immigration), Great Depression(193), ...even , the first laid off is such blacck people , after world war II , 大批黑人涌入(有题)

women:

四种观点:两段有转折,

第一段首先是说最早的观点女性 怎么怎么depression(有题), ,另一派则热中于找出一些以前不被重视的方面(有题)(转折,时间上妇女的贡献还是男人的)

第二段应该是讲另一些学者超出了public 的范畴(有题),而是 看他们在家庭的作用。

还有一片超短,我一开始以为是逻辑了

some economists think incease of the save rate will do good for the economy beacuse the save will benefit the invest the company did, but 后面说不一定 ,因为储蓄增加了, 说明购买力减小了,从而导致企业的产品没有人买, 会造成失业, 反而会影响经济

我的阅读不习惯造成了我时间的不够,我的逻辑是放在 最后一起出的(连续7题,8题?,),时间不够了,所以乱选了,所以造成我的失败,本来我感觉阅读还可以,另外我的感觉 好像sc的风格有些变化,好像以前没有涉及到这些考点,有一题刚想起来

。。。。。 the power ......

a to destroy

b of destroying

c to be destroied

我在a b 中难以选择,最后选了B

还有一体逻辑,有一种药 , 它的目的是eliminate some virus, even in the test there are no signal of such virus, it still say the medicine have the effect., since___

d It cost twice time to have the result

e some minor signal can't be tested in the current situation, 我选了E

还有一体,有一种要有什么么作用,现在的方法可以用比原来更简便的方法测出原来有病的,问criticism

我选 A 在这种新方法下可能会造成没病的给争端成有病的了

最后希望有人能告诉我,如果最后5个都选错(因为最后时间不够,而且稳定不下来了, 逻辑体酶一体都很长, 我说了一开始我把一片阅读当成是逻辑了,大家可以想像 逻辑有多长), 会造成多大 的影响,我正在郁闷呢,不知道要不要再次重考 (我 GWD 末的时候最后错4-8个,但是现在好像题目一点都不一样了,风格变了, 时间不够的现象以前没有出现过,现在怎么克服呢?希望大牛或斑竹能够告诉我,也不枉我第一个吃螃蟹,为大家带来几经。

又想到一道数学题(1月8日)

the function h(n) is defined to be product of
all the integers from 2 to 8, inclusive.
h=2^n * 3^m * 5^k * 7^l ? n+m+k+l=?

My solution:

H=2* 3 *(2^2) * 5*(2*3) *7 * (2^3)

so, k=l=1, n=1+2+1+3=7, m=1+1=2,

so,n+m+k+l=11.

This question is a little bit like the one in New prepgmat. In the exam there are some qestions like these, I spend 1 minutes on that. Now the speed is very important.

一月九日


再加两道数学题:

1. One person have quarters coins twice as many as dime coins, he also have half many five cents coins as dime coins, ? the total money of quarters /total money of five cents

2 One person come from A (approximiatedly New York) to B(Chicago) and back from a different way. (下面有点就不清了,不过反映的思路应该是对的)The average speed from A to B is 30 kilometers/ hour. What is the everage speed of total route?

(1) When he comes back, the average speed is 2/3 of the speed he come forth.

(2) the route he comes forth is 1/5 longer than that of he comes back of the total route.

另外还有四道超简单的题:一道是:

(3)一根棒子的长度和重量成正比,如果2/5那截中4公斤,剩下的那截比它重多少?(题目比较长,我简化了)

(4)长方形ABCD的面积和三角形AED的面积之比?(E在BC上)

(5)In the xy plane, the diameter of one circle is 4 (the center of this circle is at (0,0)), one line is perpendicular to the circle at (-sqrt(2), sqrt(2)) (注意,这儿就是“根号2 ”,我不知怎么打 ,原体没有这个问题, what is the slope of this line?

A -1

b 1

c 2

d-2

e sqrt(2)

注意千万别选成截距了,答案 b

(6)A, B是圆上两点,O是直线AB上一点, C是原上另一点,? O 是圆心马?(我的最后一题)

条件(1) A0=0B

条件 (2)OB=OC

我选的是C

最后希望大家要细心,还有就是速度一定要快。




答案:1. 20/1 2. C
