Being alone in outer space can be frightening. That is one reason why astronauts on solo (单独地) space
flights were given plenty of work to keep them1 . They were also in constant communication with people
on the earth.2 , being with people from whom you cannot get away might be even harder that being alone.
This is what happens on long submarine (潜水艇) voyages. It will also happen on3space flights in the
future. Will there be special problems of adjustment under such conditions?
Scientists have studied the reactions of men to one another during long submarine voyages. They have
found that longer the voyage lasts, the more serious the problem of4is. When men are5together for
a long period, they begin to feel uneasy. Everyone has little habits of speaking and behaving that are ordinarily
acceptable. In the limited space over a long period of time, however, these little habits may become very6 .
Apparently, although no one wants to be7all the time, everyone needs some degree of privacy. When
people are enclosed together, they are in what is called a stress situation. That means that they are under an
unusual amount of 8or stress.
People who are well-adjusted are able to9stress situations better than others. That is one reason why
so much care is taken in10our astronauts. These men undergo a long period of testing and training. One
of the things tested is their behaviour under stress.
