1.视力障碍的人
People with a certain eye disorder are virtually unable to see in moderatelybright light, which seems to them unbearably intense, since the cells of theirretinas are overwhelmed by moderately bright light. These people do, however,show normal sensitivity to most components of dim light. Their retinal cellsare also not excessively sensitive to red components of moderately brightlight.
The information above best supports which of the following hypotheses aboutpeople with the disorder described, if they have no other serious visualproblems?
A.In all moderately dim light in which people without the disorder can readlarge print, people with the disorder cannot read such print.
B.In an otherwise darkened concert hall, these people will see a dimlyiluminated red exit sign more clearly than small dim white lights that mark theaisles.
C.These people typically see more acutely at night and in dim light than domost people who do not have the disorder.
D.Eyeglasses that are transparent to red components of light but filter outother components of light help these people see in moderately bright light.
E.These people perceive colors other than red in the same way as do most peoplewho do not have the disorder.
F:有眼疾的人不能在普通亮光下看到东西,因为他们的视网膜细胞被这种光overwhelmed。然而这些人在昏暗灯光下又能显示出正常的视觉灵敏度。他们的视网膜细胞在面对亮光的红色成分时不会特别敏感。 C:? Q:问结论 思路:根据文意 选项:A,昏暗灯光下都能看见;B,黑暗环境视力正常;C,只是这样的症状,不能反推人家夜间视力好就是有眼疾;D,眼睛只给红色光透过,过滤其他颜色确实可以帮助他们在普通亮光下看清东西,对;E,只是说对红光不会过度敏感,又没说是不是跟人家的光感知机制一样;
2.大雾和飞机
一个机场总是被大雾笼罩,arrival 的 delay 是 10%,departure 的 delay 是 20%,但是结论是这个机场到底是不是大雾 delay 是一个 myth,选 support
A. 有的时候有 frog,但是飞机照常起飞
B. 超过半数的飞机是往来于某个城市的,这个城市的延误率特别高
C. 着陆好像更 easy了
F:机场被大雾缭绕 P:到达的延误率时10%,出发的延误率是20% C:机场是不是因为大雾延误是一个谜 Q:问支持结论 选项:A,偶尔不具有一般性;B,往来于某个城市跟雾没有关系;C,大雾环境下着陆更容易,解释了到达的延误率为什么比出发的延误率低,所以能判断出机场是不是因为雾天延误了,对;
3.养猫还是狗
In United states-today,有1/3 的人家里至少有只猫,有1/3 的家里至少有只狗,但是统计数据表明有 half of united states families have neither dog nor cat, even anyother pets. 问解释。
F:美国有1/3的人家里有只猫,1/3的人家里有只狗 C:统计数据表明一般的美国家庭没有猫也没有狗甚至没有其他宠物 Q:问解释 思路:有些人家里又有猫又有狗;统计数据有问题 方向:喜欢宠物的家庭一般养猫又养狗;部分美国人在接受调查时没有如实回答 |
