问题 Which of the following statements is NOT true according to the passage?
What is the meaning of "......the PSAs offer a virtual presence for ground crews and scientists, ...... " (Paragraph 1) ?
选项 A、With the help of PSAs, the ground crews and scientists can present in real time in the spacecraft.
B、With the help of PSAs, the ground crews and scientists can control the spacecraft as if they were there.
C、With the help of PSAs, the ground crews and scientists cannot in real time present in the spacecraft.
D、With the help of PSAs, the ground crews and scientists cannot advise the astronauts to deal with different situations.
答案B
解析 关键理解virtual的意思。这里virtual表示“实际的”，意思就是利用PSAs上的视频道话功能，地面工作人员和科学家就能实时“实地”地去执行各项工作。因此他们不是真正地上了太空船船或太空空间站，而是借助PSAs而模拟实境地去处理事情，故答案只选B。
