上来直接把狗主给虐了。狗主得了5分，大大超出我的意外。虽然5分没有什么好骄傲的，但是它第二题就给我来了外星图，在它上面花了我太多太多的时间，以至于到了后来时间根本不够了，然而我还剩5道题。只能赶紧全部点C，但是点到倒数第二道时系统因为时间到自动把我踢出了。就是这样我还有5分，服了自己。证明自己对那个外星图的推断是对的。这个梗请看图片。

1. 一个公司找出80个员工来参与survey，其中75人回复了。service的内容是对于跟环境污染的态度有关的，后面是表格注明每个选项点选的人数。一个人可以点选多于一个选项。后面的问题是有关其中具体选项的参与人员与参加人数的一些比较。记得要读清题目选择是用 80/75做总人数做题，这两个数字是不一样的。
2. 第二题，虐我致深，

JOHN take 了一个program A，然后下面有三个图，分别是他每个阶段take 时的得分等情况。然后后面的页面有很多人一起的图表，每人来一个，然后问这些人哪些是take 了program A 的。图标很奇怪，并没有告诉那些线条是干什么用的。于是我花费了很长的时间研究......
我把每个人的图表跟JOHN 的对比，完全一样的是YES，不一样的是NO,

这道题应该做错了，我还没搞懂这些图表的含义。

图表请看图：

逻辑：
1，因为一个地区的牛（忘记是什么肉了，用牛代替）特别多，所以它的价格下跌。然而给牛喂得饲料变得很少，所以牛肉应该会价格上涨。事实并非如此，牛肉还是下跌的，为什么？
2. 事实证明，看电视少的人会更Happey, 为了让人更 happier, 现在要实行政策来降低人们看电视时间。the most volunary fact to the critisim 是哪项？
3. 试验：给病人用止疼药的时候换成假的，问的时候，所有被用了假药的都说疼痛减轻了。那是因为当他们以为他们是在用止疼药是，潜意识引起的。当 secretely 把药换成另一种，（这种药能抑制止疼药发挥作用）的时候，病人却说疼。为什么？选项里面有一项是：当他们知道那是抑制止疼药的药物时，心理作用会觉得疼。我一看就秒选了，当意识到错误来不及了，叙述中说到了 secretely，所以那些病人是不知道的。

1.蛇，2 恐龙的牙齿，都是前面JJ有过的。
有一个之前没看到的：当物价过高时，政府会通过一项目，enlarge size，这样的企业大规模生产东西来调控价格。但是政府除了参与这种还有别的方案，就是自己购入和放出商品。当物价太低时购入，使得市场流通小，价格上调。价格高反之，企业比较喜欢这种。他们东西既能卖出，价格又好。

请问IR 第一题是这个么？

还有一个比较复杂的题，应该是有两个选项卡。
第一个选项卡就是两段文字：第一段就是介绍有个组织有80个成员，然后他们都是因为bla,bla,bla,bla这四个原因加入进来。但其实咧，这个组织只跟其中一个原因有关，那就是水资源的保护（反正就是跟水有关）。然后应该是还提到了调查了这些成员几个问题。第二段就是讲了这个组织有两个mission：一个就是recycle，组织的75%的资源都用在recycle；另外一个就是培训成员什么的。。
第二个选项卡就是调查的结果，有两个表格。第一个表格的列就是三个问题ABC的，行就是组织mission/模块的名称：A问题是组织每个模块有几个人参加，B问题是对于每个模块，有多少人觉得是重要的，C问题是对于每个模块，有多少觉得组织应该最为重视。（BC问题可能没记得清，但大概就是这样。。）第二个表格有三行DEF，具体不太记得了。。因为没怎么考到。。（备注：我不记得D是第一个表格，还是第二个表格去了。。）
然后题目主要就是if yes的那种：
**问ABC问题中，哪个问题有至少有一个人是多选：就是利用80个成员，然后表格数字横向相加，超过80的就选它。我选的A
**问ABCDEF中，除了哪个的结果，其他的都表示组织成员认为recycle重要：我用的排除法，选的是B

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
