以下是引用blackblue在2007-11-6 10:35:00的发言：9. Astronauts who experience weightlessness frequently get motion sickness. The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. The astronauts’ experience is best explained by the hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness. Which one of the following, if true, provides the strongest additional support for the hypothesis above? A. During rough voyages ship passengers in cabins providing a view of the water are less likely to get motion sickness than are passengers in cabins providing no view. B. Many people who are experienced airplane passengers occasionally get motion sickness. C. Some automobile passengers whose inner ears indicate that they are moving and who have a clear view of the objects they are passing get motion sickness. D. People who have aisle seats in trains or airplanes are as likely to get motion sickness as are people who have window seats. E. Some astronauts do not get motion sickness even after being in orbit for several days. 这道逻辑题太晕了：答案A。不太明白The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. 想说什么意思。也不明白答案A跟它什么关系  这个是费费的题吧 答案：A 思路：搭桥法，建立A与B的联系。仔细读题可知：这种运动性疾病是由于大脑接受了不同的矛盾的信息。有两个信息源：一个来自内耳（静止），一个来自眼睛（运动）。 选项中只有A,C,D涉及这样两个信息源。 A指出接受两种不同的信息较容易获得运动性疾病比起获得两种一致的信息。C：虽有两种信息，但两者是一致的（都是运动的）。 C, D：指出接受两种一致的信息较容易获得运动性疾病比起获得两种不同的信息。与题目的例子相反。所以只有A是正确选项。
astrounaut see move,ear motionless 船舱内passenger see motionless,ear move刚好反的，原文中是对静止的感知，应用中是运动的感知 |
