天空一号与神八第一次对接时间.要具体点,

D

1.The astronauts could do lmost anything when they lived in the Tiangong-1.
2.It was in London that the 30th Olympic Games was been held.(这是一个明显的考查强调句型的句子)
3.There was a time when he was obsessed with comeputer games.
4.That was the first time for him to stand on the stage of CCTV.句型 that was the first time for sb to do sth.
5.I found that it was impossible for me to express what he wanted to say. found是短暂性动词,一般不用完成时,其次“做……是不可能的”是句型“it is/was impossible for sb to do sth”

11月02号23点左右开始变轨 实际23点08分开始 现在神八在圣地亚哥 将会在陕西甘肃上空进行首次对接 预计在23点半进行交汇对接

设神舟八号的周期为T2

T2=（r2XT1X根号下r2/r1 ）/r1

有很多原因 主观来讲 要探索外星 客观呢 应该是资源枯竭

运动状态是相对静止
