12月16号一战730 (M50 V38), 微量JJ

CD是个好地方, 我从中得到了很多有用的信息, 多谢CD 和众CDer了!!

分数不算高, 但对我要申请的学校肯定够用了,所以不会去2战啦.

有些刚想起来的机经我发到后面的帖子了,就不在贴回本帖啦.

AA: 说一个地方的三种business: theater, pizza 和golf club获得了成功,增长很多. 于是公司计划在另外一个地方展开同样的三种business. 并且为了公司利益最大化, 决定对那些参与了两种business activities的人在参与第三种时给予折扣, 因为这样能吸引到更多的客户.

AI: An art exhibition or public performance should be cancelled if there is any objection in the community.

数学:

1. DS题. 问m^n < n^m?

a) m < n

b) n<=2m

我选的是A [补充--这个答案貌似错了, 多谢勇敢做梦MM提醒.呵呵.]

申明: 我的答案不一定正确, 大家参考而已. 呵呵.

2. 一家商店买入桌子和椅子, 桌子50块一张,椅子5块一把. gross profit是每张桌子的买入价的30%, 每张椅子买入价的50%. 商店卖光了所有买入的桌椅, 最后gross profit总和是$550. 问total revenue是多少? 我选的是$2050那个选项.

Verbal:

思绪凌乱中..等整理好了再来更新..

祝所有即将考试的的兄弟姐妹好运!!

补充:

Verbal 阅读, 4篇都在机经里见过.

1. boater

第一段讲某地(一个湖吧)N年前供游客租用的船较少, 近年增加了很多, 而且同时私人购船也增多了, 因为有减税政策. 所以一般预期来这里的游客会觉得地方变拥挤了.　但事实相反,　去那里的游客不觉得the place becoming crowded. 于是作者推测,　大约是由于changes in norms, preference of the visitors.

第二段描述这样的change. 说船变多了,很多人以前没来过,现在想来了 (即菜鸟). 菜鸟们考虑的都是安全阿,谨慎之类的. 有时候乐意去人多的地方,以便出了事好求救.

有一道题问第二段的作用. 我选的是elaborated the explaination provided in previous pagragraph.

2. 罗斯福

这个已有的机经很详细了,  对我帮助巨大. 当时已经超时pace了, 看到这篇文章立刻心定了, pace赶上来了.

有一道题好像问斯大林的特点, 我选的是他在晚上工作那个.

还有一道问: this article most strongly suggested which of the following?

A) 那个美国元帅在罗斯福手下工作得很郁闷

B) 斯大林和希特勒都具军事才能

C) 国家制度影响领袖风格

D) 

E)

我选C) (这里的ABCDE是我乱拍的, 不是原题顺序)

3. 果酱题

有一道题: which of the following, if true, will call into question of the arguement of the author

我选的是在那个六个果酱选一个的group里, 有这个group里的人很喜欢的一个牌子. 而在面对24种果酱的group里,不存在这样的牌子.

4 伽利略和水泵

主题题: 我选的traced how two scientists attempted to explain a particular phenomenon by experiments.

CR题:

有一道以前遇过的原题, 讲人被一种deer的tick上带的细菌传染得病. 这种病菌来自一种white mice. 我这题瞎做的,选哪个记不清了, 极有可能也选错了. 大家可以找找原题.

[补充]上面这道CR就是这个, 一模一样

Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected whitefooted mice. However, certain other species on which the larvae feed do not harbor the bacterium. Therefore, if the population of these other species were increased, the number
of ticks acquiring the bacterium? and hence the number of people contracting Lyme disease—would likely decline.
Which of the following, if true, most strengthens the argument?
A. Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
B. There are no known cases of a human’s contracting Lyme disease through contact with white-footed mice.
C. A deer tick feeds only once while in the larval stage.
D. A single host animal can be the source of bacteria for many tick larvae.
E. None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans.

是呀! 看来我这道错了...难怪记忆深刻.

再申明一下, 我给的答案是我选的, 很可能出错. 仅供大家参考阿!

这题谁见过没？

找到了.呵呵, google就是强大. 一模一样的原题. 这题我肯定选错了, 现在都忘了选了什么. 是我pace乱掉的时候做的.

这题cr:

ans:c

想起了一道数学:

1. 10个children捐了28件衣服. 捐了不同数目衣服的children数目集合的range是2. 问下列那个可能是捐了3件衣服的children数目:

I) 0

II) 5

III)9

我记得选得是I) and III).

另外一道DS:

一车行卖车, 卖出的sedan, suv(姑且认为是SUV),以及van的数目比例是4:5:7. 问车行卖了多少van?

a) 10<sedan和van的数目之和<20

b) sedan的数目<10

我选的A
