690分这个让人心塞的分数。。。V最后剩下一分钟还有10道题没答，于是都是蒙的==蛋碎。。纠结要不要重考

AWA: 一个cell phone公司，生产需要使用precise，expensive metals，然而最近几年metals 的价格fluctuate dramatically，同时企业production有continued growth，于是公司建议低价大量采购，这样能够lock costs，同时保证有high profits
我的攻击点是：1）锁定了metal的成本，未必锁定所有成本，其他成本还包括人力资源、广告、设备等
2）成本低，也不代表能够high profits
3）企业无法锁定最低的价格，将来可能出现更低的，万一采矿成本变低了什么的
4）将来可能会出现其他的材料代替metal来生产，不需要metal了怎么办

1）一块边长为300的正方形地分成九块，也就是说横着切两刀，竖着切两刀。而这块地是坐北朝南的，如果我们知道左下边第一块地的南边的边长，还有西边第二块地的西边的边长，要想知道东北角上的地的边长，还需要知道哪两块地的哪条边长（注：题目就是全描述的，并没有图。。。自行脑补）
2）又是那种三个sheet的题目。。。因为最后剩下的来不及做完，于是我只记得部分内容，就是说某低从199*年开始到201*年，每年发生多少起火灾（具体x1,x2,x3,x4...），而每年的火灾分别由人为和自然发生组成（分别为A1,B1;A2，B2.....），然后问哪一年是最干旱的一年。。。
3）问说有两个东西，一个digital，一个physical，然后year 1 year 2两年分别的数量是给了折线图。。。然后问两年变化的一些问题，考试的时候看图就能明白了4）大家针对几样方案进行投票，投票结果以几星表示，每样选项，需要对两个方面进行投票，只有两样投票都达到最高，才能实施该方案，然而最后没有一个方案是达到最优的



数学
1）PS:某人有5分钱的硬币x，10分的硬币是5分硬币的2倍，20分硬币是10分的3倍（其中2倍，3倍是狗主自己编的，懂理就行），然后问这个所有5分钱的combined value 比 所有10分钱的combined value的ratio，注意是value的比值，所以要有几分乘以数量

1）公司多元化
公司的合并可以有两种方式，一种是diversification（非相关产业合并），一种是horizon（也即产业内相关产品的合并），由于horizon会导致整个industry less competitive，于是
长久以来公司的多元化都被认为是因为反垄断所造成的。而diversification并不会受到challenged，因为他们并不会威胁竞争。按照这种情况来理解，这些不受challenged的企业应当大量合并成大公司，然而，actually（考了这个actually词的作用==），大型的多元化公司并没有比小的多元化公司多
同时，反垄断在西方经济中其实就US推崇，然而其他国家也是没有大型合并公司，甚至有某国家是提倡horizon 合并的，还是没有大型合并公司
2）女权变化
随着社会从livestock 想wage labor转变，很多人都认为女性的社会地位是降低的，实则不然，因为当社会转变后，女性可以从事不同的职业，有些女性是从事teaching这种高级工作，有些是从事很low 的工作，而高级工作的女性其实地位更高了，也就是说社会转变导致了女性地位的两极分化

你做的是不是这篇：
In terrestrial environments, gravity places special demands on the cardiovascular systems of animals. Gravitational pressure can cause blood to pool in the lower regions of the body, making it difficult to circulate blood to critical organs such as the brain. Terrestrial snakes, in particular, exhibit adaptations that aid in circulating blood against the
force of gravity.
The problem confronting terrestrial snakes is best illustrated by what happens to sea snakes when removed from their supportive medium. Because the vertical pressure gradients within the blood vessels are counteracted by similar pressure gradients in the surrounding water, the distribution of blood throughout the body of sea snakes remains about the same regardless of their orientation in space,provided they remain in the ocean. When removed from the water and tilted at various angles with the head up, however, blood pressure at their midpoint drops significantly, and at brain level falls to zero.
That many terrestrial snakes in similar spatial orientations do not experience this kind of circulatory failure suggests that certain adaptations enable them to regulate blood pressure more effectively in those orientations.
One such adaptation is the closer proximity of the terrestrial snake's heart to its head, which helps to ensure circulation to the brain, regardless of the snake’s orientation in space. The heart of sea snakes can be located near the middle of the body, a position that minimizes the work entailed in circulating blood to both extremities. In arboreal snakes, however, which dwell in trees and often assume a vertical posture, the average distance from the heart to the head can be as little as 15 percent of overall body length. Such a location requires that blood circulated to the tail of the snake travel a greater distance back to the heart, a problem solved by another adaptation. When climbing, arboreal snakes often pause momentarily to wiggle their bodies, causing waves of muscle contraction that advance from the lower torso to the head. By compressing the veins and forcing blood forward, these contractions apparently improve the flow of venous blood returning to the heart.
The passage provides information in support of which of the following
assertions?
(A) The disadvantages of an adaptation to a particular feature of an environment
often outweigh the advantages of such an adaptation.
(B) An organism's reaction to being placed in an environment to which it is not well adapted can sometimes illustrate the problems that have been solved by the adaptations of organisms indigenous to that environment.
(C) The effectiveness of an organism's adaptation to a particular feature of its environment can only be evaluated by examining the effectiveness with which organisms of other species have adapted to a similar feature of a different environment.
(D) Organisms of the same species that inhabit strikingly different environments will often adapt in remarkably similar ways to the few features of those environments that are common.
(E) Different species of organisms living in the same environment will seldom adapt to features of that environment in the same way.
Answer: B
According to the passage, one reason that the distribution of blood in the sea
snake changes little while the creature remains in the ocean is that
(A) the heart of the sea snake tends to be located near the center of its body
(B) pressure gradients in the water surrounding the sea snake counter the effects of vertical pressure gradients within its blood vessels
(C) the sea snake assumes a vertical posture less frequently than do the terrestrial and the arboreal snake
(D) the sea snake often relies on waves of muscle contractions to help move blood from the torso to the head
(E) the force of pressure gradients in the water surrounding the sea snake exceeds that of vertical pressure gradients within its circulatory system
Answer: B
It can be inferred from the passage that which of the following is true of
species of terrestrial snakes that often need to assume a vertical posture?
(A) They are more likely to be susceptible to circulatory failure in vertical
postures than are sea snakes.
(B) Their hearts are less likely to be located at the midpoint of their bodies than is the case with sea snakes.
(C) They cannot counteract the pooling of blood in lower regions of their bodies as effectively as sea snakes can.
(D) The blood pressure at their midpoint decreases significantly when they are tilted with their heads up.
(E) They are unable to rely on muscle contractions to move venous blood from the lower torso to the head.
Answer: B
The author describes the behavior of the circulatory system of sea snakes
when they are removed from the ocean (see lines 17-20) primarily in order to
(A) illustrate what would occur in the circulatory system of terrestrial snakes without adaptations that enable them to regulate their blood pressure in vertical orientations
(B) explain why arboreal snakes in vertical orientations must rely on muscle contractions to restore blood pressure to the brain
(C) illustrate the effects of circulatory failure on the behavior of arboreal snakes
(D) illustrate the superiority of the circulatory system of the terrestrial snake to that of the sea snake
(E) explain how changes in spatial orientation can adversely affect the circulatory system of snakes with hearts located in relatively close proximity to their heads
Answer: A
It can be inferred from the passage that which of the following is a true
statement about sea snakes?
(A) They frequently rely on waves of muscle contractions from the lower torso to the head to supplement the work of the heart.
(B) They can not effectively regulate their blood pressure when placed in sea water and tilted at an angle with the head pointed downward.
(C) They are more likely to have a heart located in close proximity to their heads than are arboreal snakes.
(D) They become acutely vulnerable to the effects of gravitational pressure on their circulatory system when they are placed in a terrestrial environment.
(E) Their cardiovascular system is not as complicated as that of arboreal snakes.
Answer: D
The author suggests that which of the following is a disadvantage that results
from the location of a snake's heart in close proximity to its head?
(A) A decrease in the efficiency with which the snake regulates the flow of blood to the brain
(B) A decrease in the number of orientations in space that a snake can assume without loss of blood flow to the brain
(C) A decrease in blood pressure at the snake's mid point when it is tilted at various angles with its head up
(D) An increase in the tendency of blood to pool at the snake's head when the snake is tilted at various angles with its head down
(E) An increase in the amount of effort required to distribute blood to and from the snake's tail
Answer: E
The primary purpose of the third paragraph is to
(A) introduce a topic that is not discussed earlier in the passage
(B) describe a more efficient method of achieving an effect discussed in the previous paragraph
(C) draw a conclusion based on information elaborated in the previous paragraph
(D) discuss two specific examples of phenomena mentioned at the end of the previous paragraph
(E) introduce evidence that undermines a view reported earlier in the passage
Answer: D
In the passage,the author is primarily concerned with doing which of the
following?
(A) Explaining adaptations that enable the terrestrial snake to cope with the effects of gravitational pressure on its circulatory system
(B) Comparing the circulatory system of the sea snake with that of the terrestrial snake
(C) Explaining why the circulatory system of the terrestrial snake is different from that of the sea snake
(D) Pointing out features of the terrestrial snake's cardiovascular system that make it superior to that of the sea snake
(E) Explaining how the sea snake is able to neutralize the effects of gravitational pressure on its circulatory system
Answer: A

DS：数字A除以6余数是多少：
(1)A除以12的余数和3的余数相同
(2)数字A除以4余2

12的余数和3的余数相同，说明A=12P+1 or A=12P+2，所以余数可以是1or2 （1）不充分，(2)不充分，可以有多个余数，但是说明A必是偶数，所以1+2 充分。
