总的来说是够用的分数。我是数学差的文科生,居然满分,万分感谢截至昨晚的182道数学狗和半夜给我答疑的某女。今天还是在剩余0秒的时候,以电光火石的速度点击确认的最后一道题。。。我一向都是用完数学的75分钟的,不浪费。个人觉得这个月的数学比十月的简单。难度介于prepog之间,如果做完了prep数学的同学,应该不用担心数学。



Verbal我一直觉得在开飞机,没进入状态。前面十道题花了20多分钟,最后5道题只有3分钟了,所以最后5题基本上不知道题在说什么,乱点的,说不定连错。可能真的是有高分题库的说法,所以最后是30+



使劲回忆了些狗狗,希望能帮助到大家。



作文:

AI: Whether employers should prevent employees from engage in unhealthy behaviors?

AA: The following appeared in a memorandum from the Director of Human Resources to the executive officers of Company X.

Last year, we surveyed our employees on improvements needed at Company X by having them rank, in order of importance, the issues presented in a list of possible improvements. Improved communications between employees and management was consistently ranked as the issue of highest importance by the employees who responded to the survey. As you know, we have since instituted regular communications sessions conducted by high-level management, which the employees can attend on a voluntary basis. Therefore, it is likely that most employees at Company X now feel that the improvement most needed at the company has been made.”



数学:

1. 某人在一家银行存了一笔钱,利率是X percent;在另外一家银行以利率y存了相同金额的一笔钱,一年后两笔存款的利息相同,问y是多少

1)告诉本金

2X=5

B



2. 某城市有大约250,000的人口,年增长率是1%,问5年后大概人数。

选项

A 260,000  

E 300,000

我选的A



3.有个陷阱题:x<2-5y y3,问x的最大整数取值,最后三个选项是-14-13-12

我选-14



4.L, R,J,三人共享$12,000,问谁拥有的金额最大

1L<R

2J最多有$4,000

我选的C



5.第一题是1/(x-1)-1/(x+1)





确认37题的V2是正确的,我再复制一遍:

一个数字n,既可以等于三个连续正整数abc的和,a<b<c, 也可以等于三个连续正整数xyz 的积,x<y<z, n5除的余数。

条件一是a5除的余数为1

条件二是x5除的余数为1



逻辑

还有道GWD1-Q22题,但是boldface部分变换成下面这样了:

City Official:  At City Hospital, uninsured patients tend to have shorter stays and fewer procedures performed than do insured patients, even though insured patients, on average, have slightly less serious medical problems at the time of admission to the hospital than uninsured patients have.  Critics of the hospital have concluded that the uninsured patients are not receiving proper medical care.  However, this conclusion is almost certainly false.  Careful investigation has recently shown two things:  insured patients have much longer stays in the hospital than necessary, and they tend to have more procedures performed than are medically necessary.

In the city official’s argument, the two boldface portions play which of the following roles?

我当时纠结于2个选项,因为其他三个选项都说得一个粗体是conclusion

C.2个都支持结论

E.第一个支持结论,第二个粗体加强第一个粗体



我想even though表示让步,所以还是选择的C



确认42.硫化钠洗衣粉  

硫化钠(sodium sulfur)是一种洗衣粉里面的原料。传统洗衣粉里面有很多硫化钠,现在新兴的浓缩洗衣液(liquid concentrate detergent)用硫化钠比传统的少,可是最近硫化钠生产商发现浓缩洗衣液制造商购买硫化钠的量上升了,而事实上人们使用传统洗衣粉(powder detergent)却没有上升,为什么
我记得第一个选项很迷惑,差点上当,说很多人觉得传统洗衣粉环保还是洗得干净还是不伤洗衣机什么原因,开始用传统洗衣粉了(事实上最后一个话已经排除这个可能了)
我选了生产商发现增加硫化钠的使用量可以忽略另外一些昂贵的原料。



其实注意了最后问的是让解释为什么powder detergent的销量没上升,就很好选择了,同意原作者答案。





阅读

1. 基因和语言的关系

以前人们根据基因分析认为北美语言最早起源于的4wave还是group,但是研究发现,基因和语言关系不大,举例trading language(有道举例作用题)。接着说后来其实北美语言来自3group,人数是很small的,(这个small有考点)。有道主题题。



2.穷国家反常的资金流

第一段Poorer countries的资金应该是外部向内流入的流向,可是研究发现,居然是向外部流。这应该是富国才有的现象啊。针对最后一句话出了考点

第二段讲为什么穷国的资金流应该是由外向内流。无非就是穷国没钱,所以应该是别国向他们投资。

第三段记不清楚了

第四段解释为什么现实中资金流是由内往外。因为穷国信用不高,借不到钱。而穷国群众有钱了,就存起来,然后向富国invest



总之是很简单的文章,逻辑清楚,句子也不难。
