From the first use of the rochet to carry satellites 这篇阅读理解的答案
从首次运用火箭运载卫星进入太空到太空站的设立,人类在太空研究中做出了巨大的努力.目前为止,已获得了许多项的成功,但我们面前仍面临许多的其他任务,要求我们不能一直不前,要不断进步.
国际太空站的设立是我们在太空探索中所采取的非常重要的一步.不但起到一定的帮助作用而且也是必要的存在.它为我们许多长久性的实验提供了一个适当的太空环境,也是地球和宇宙观察的一个基地.也是未来探索月球和火星的基地.总之,如果我们想进一步探索太空,首要的事 就是建立太空站.
由于太空站的建立耗资巨大,所以单个国家很难完成.美国似乎唯一一个可以靠一国之力建立太空站的国家,并且应经进行尝试,但结果并不十分成功.所以它结合了多个国家之力共同建立太空站.虽然仍然很昂贵,但相对于个人之力,已经很便宜.这确实是一项需要所有人共同付出的任务,同时也是共同受益的活动.
但即使这样,资金的筹集仍然是一个大问题.对于美国来说,似乎需要花钱的地方太多.虽然是世界上最富有的国家,但美国每年的债务也很多.它需要在金融方面做一定的筹备,尽力在所有这样的问题中获取一定的平衡.
