第1415期:Working in space

Bored with your life? Dreaming of something different? When I feel like that I look up and wonder what life would be like 400km above my head. 厌倦了你的生活？梦见不一样的东西？当我有这种感觉时，我会抬起头，想知道在我头顶 400 公里处的生活会是什么样子。That's where the International Space Station orbits the Earth, with six astronauts living and working on board, for months at a time.那是国际空间站绕地球运行的地方，有六名宇航员在船上生活和工作，每次几个月。How do they sleep? They spend the night floating in a sleeping bag inside a small cubicle on the ceiling. 他们怎么睡觉？他们在天花板上的一个小隔间里的睡袋里过夜。American astronaut Sunita Williams explains: "It's like a little phone booth but it's pretty comfy and it doesn't matter if I turn over and sleep upside down. 美国宇航员苏尼塔·威廉姆斯解释说：“它就像一个小电话亭，但很舒服，我翻身倒睡也没关系。I don't have any sensation in my head that tells me I'm upside down."我脑子里没有任何感觉告诉我我颠倒了。”Brushing your teeth in a place where you can't have a tap or a sink can be a challenge. 在没有水龙头或水槽的地方刷牙可能是一项挑战。Can you imagine the mess that running water would make in zero gravity? 你能想象在零重力下流水会造成什么混乱吗？Canadian astronaut Chris Hadfield uses a straw to put a big blob of water from a sealed bag onto an ordinary toothbrush and adds a little toothpaste - which he has to swallow when he's done.加拿大宇航员克里斯·哈德菲尔德（Chris Hadfield）用吸管从密封袋中取出一大团水到普通牙刷上，然后加入少许牙膏——完成后他必须吞下。Daily exercise is essential. The lack of gravity makes bones more brittle and muscles lose strength – so astronauts are encouraged to work out for at least two hours a day.日常锻炼是必不可少的。缺乏重力会使骨骼更加脆弱，肌肉也会失去力量——因此鼓励宇航员每天至少锻炼两个小时。The role of astronauts in the International Space Station is to act as lab technicians for scientists back on Earth. 宇航员在国际空间站的作用是为地球上的科学家充当实验室技术员。So they spend their time maintaining their environment and performing and monitoring experiments in a confined space about the size of a Boeing 747.因此，他们将时间花在维护环境，并在波音 747 大小的密闭空间中进行和监控实验。 Almost every task is carefully planned by mission control - although most astronauts spend their first days losing stuff until they get used to sticking everything they use to the walls with Velcro, duct tape or clips.几乎每一项任务都由任务控制中心精心计划——尽管大多数宇航员在第一天会丢失东西，直到他们习惯用魔术贴、胶带或夹子将他们使用的所有东西粘在墙上。One of their most valued perks is the view from "the office", dominated by that gigantic blue ball down there, sitting in the darkness of space. 他们最看重的好处之一是“办公室”的视野，由下面那个巨大的蓝色球主宰，坐在黑暗的太空中。Wow! Absolutely breathtaking!哇！绝对令人叹为观止！词汇表International Space Station  国际空间站to orbit  环绕……轨道运行an astronaut  宇航员a sleeping bag  睡袋comfy  舒服的upside down  倒置地，颠倒过来地gravity  重力sealed  密封的essential  必不可少的brittle  容易断裂的lab technician  实验室技术人员a confined space  一个有限的空间mission control  航天地面指挥中心Velcro  尼龙搭扣duct tape  牛皮胶布perk  好处breathtaking  令人惊叹的，壮观的
