答案
Space Gym Physical fitness is an important part of being an astronaut. / Astronauts must be healthy enough to perform tasks while in space, / such as taking a space walk to repair an external piece of equipment. / In space, muscles, including the heart, can lose strength and endurance / as they don’t have to interact with gravity. / Astronauts use athletic equipment modified for this special environment to maintain their physical fitness. / For example, a special running machine is used to increase their endurance, / so they can work for longer periods of time without getting tired. / They also pull against vacuum cylinders, / which lack air, to create resistance and work their muscles. / And they ride an unusual stationary bicycle to help improve the health of their hearts. / Astronauts have to strap in to this bicycle, / because a lack of gravity prevents them from sitting down and staying put. / Special shoes also snap into its pedals / to make sure astronauts don’t just float away. /
解析
太空健身房
成为一名宇航员,身体健康是一个重要条件。宇航员必须足够健康才能在太空中执行任务。在太空里,包括心脏在内的肌肉会失去力量和耐力。宇航员使用专为这种特殊环境改良过的运动器材来维持其身体的健康状态。例如,一种特制的跑步机就可以用来帮助增加宇航员的耐力。他们也会拉真空筒,使肌肉得到锻炼。
