2021年考博英语英汉互译复习：宇航员进行太空旅行训练

在实验室里，宇航员进行太空旅行训练。其所处的环境与太空飞行的环境相仿。他们需要花很多时间准备适应太空中发生的巨大变化。当太空船以极快的速度离开地球时，宇航员感到他们仿佛被挤压向宇宙飞船底板。此后，当他们离开引力区时，他们就无法停留在一个地方。就连吃饭、喝水等简单动作都变得非常困难。假如你在倒立或躺卧时试图喝一杯水，那么你就会对宇航员必须应付的环境略有了解。

In the laboratories where astronauts are trained for their journeys, they are subjected to conditions that resemble those of flight. It take time for them to prepare for the great changes that occur in space. When the space ship leaves the earth at tremendous speed, the astronauts feel as if they are being crushed against the spaceship floor. Later, when they leave the zone of the earth’s gravitation, they are unable to stay in one place. Simple actions, such as eating and drinking, become very difficult to perform. You may get an vague idea of what the astronauts have to deal with if you try to drink a glass of water while standing on your head or while just lying down.
