题目中不是说了吗“Develop a comprehensive ten-year plan complete withcosts, payloads, and flight schedules to maintain the ISS”,那你就从costs,payloads和flight schedules来分别讨论嘛。。。。然后下面还给了“Some interesting facts possibly worthy of your consideration”,你自己再结合看看嘛。。。。主要还是自己查资料了,自己建模型,然后看看自己的模型效果怎么样了。。。。不要期待着别人把现成的东西给你,那是不可能也是没意思的,是不是?...
