课文翻译：空间站的生活在太空生活是每个想成为宇航员的人的梦想。我在空间站的六个月已经结束了，这是一次充满挑战但奇妙的冒险。我敢保证你很想知道太空中的日常生活是什么样子，以及它与地球上的生活有什么不同——低重力肯定会使平常的事情变得不同寻常!从睡觉的那刻起，我们就能明显感受到在太空生活的奇妙。由于太空中近乎没有重力，我们必须把自己固定住，才不会四处飘浮。我们通常睡在独立的睡眠区，更像是大的橱柜，或者睡在固定在墙上或者天花板上的睡袋里。尝试背部没有压力入睡是奇怪的，但我们不再为这些特别的床而烦恼了。在约八小时的睡眠后，我们开始了一天的工作。日常工作占用了一天里大部分时间，要求很高，但它们也会非常有意义。我们的主要任务是进行科学研究。我们需要评估低重力对动植物的影响。诸如老鼠、鱼、蚊子等生物也被送到了空间站!在低重力环境下，我们可以通过显微镜更多地了解细胞和微生物的变化。除了做这些生物实验，我们还开展其他研究领域的实验。我一直在做一个实验，可以定位并追踪地球上大片区域的闪电。希望这个实验能使人们进一步了解地球气候，并更好地做好雷电防护。空间站里发生那么多事情，需要大量的维护，所以我们经常检查空间站的支撑系统，并做一些清洁工作。当我们需要在空间站外面执行任务时，例如测试新设备、监测科学实验或修理空间站，就会产生最具挑战性的工作。在这种情况下，是时候来场太空行走了。首先，我们穿上太空服，它们可以让我们在太空中呼吸，保护我们免受寒冷和辐射的伤害。然后我们走出空间站，有时执行任务要连续好几个小时，向下可以看到美丽的地球。尽管地球上的景色美妙绝伦，但太空行走并不像你们可能想象的那么激动人心。这可能是最危险的工作，因为有电击之类的潜在风险。这就是为什么(我们)要仔细规划好每次的太空行走。考虑到低重力环境，太空中的饮食也大不相同。大多数食物都是脱水或冻干的。吃到新鲜的食物是一种奢侈，因为水果和蔬菜等新鲜农产品只能每隔几个月从地球运到空间站。盐和胡椒粉仅以液体的形式存在，这样它们就不会飘来飘去，堵塞通气管。但是，液体在太空中不容易控制。我们必须用塑料细管
