问题 Everyone who travels in space suffers from feelings of motion sickness initially.
The passage mainly describes the psychological health risks during the voyage to Mars.

选项 A、Y
B、N
C、NG

答案B

解析 文章首句提出motion sickness的问题,接着讲了身体其他方面的情况,直到第八段才涉及psycho logical health的问题,下面又谈身体的问题,因此文章主题是讲健康问题,心理健康只是其中的一小甜分。
