【分析】本文是一篇说明文。文章介绍了人类探索太空的历史。
1.考查过去分词。句意:天文学是人类知道的最古老的科学。the oldest science是know动作的承受者,故用过去分词known作定语,表示被动。故填known。
2.考查被动语态。句意:但是人类被限制在只能用眼睛观察到的六个星球上。根据句意可知此处为被动语态, be limited by被……所限制。故填limited。
3.考查介词。句意:但是人类被限制在只能用眼睛观察到的六个星球上。用眼睛观察应用介词“with”。故填with。

8.考查连词。句意:人类的视力如此有限以至于看不到所有的星球。根据句意结合空后的形容词limited,可知此处考查结果状
