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.

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。

请问:A中哪里可以看出接受的是两种不同的信息,一个是静止一个是运动?

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.

有参照物才知道自己的运动，失重状态，参照物和自己都不动，所以感觉不倒自己的移动

A：有参照物和没参照物的比较，前者更能感觉到移动
