【分析】这是一道英语补全短文题，解题时需先把握文章主旨（太空垃圾的危害及解决办法），再结合上下文的转折关系、指代关系、语义递进逻辑来匹配句子。第1空前文提到能看到星星和月亮，后文转折引出太空垃圾，需选转折句；第2空前文介绍太空碎片数量，后文说明其危害，需选解释碎片危险原因的句子；第3空前文提及碎片对宇航员的危险，后文说“太可怕了”，需选程度更深的危险表述；第4空前文问解决办法，后文说某做法不可能，需选对应做法的问句；第5空前文列举解决方法，后文说期望，需选总结方法作用的句子。
【解析】1. 第1空：前文说能看到星星和月亮，后文转折引出太空垃圾，A选项“但我们看不到的是太空中的垃圾碎片”符合转折逻辑，故选A。2. 第2空：前文介绍太空碎片数量，后文说它们能撞击卫星，F选项“这些碎片非常危险，因为它们移动得太快”解释了危险的原因，衔接上下文，故选F。3. 第3空：前文提到碎片对宇航员危险，后文说“太可怕了”，E选项“未来，一块太空垃圾甚至可能从天空落到地球并击中人类”进一步说明危险，程度加深，符合语境，故选E。4. 第4空：前文问该怎么办，后文说“那似乎不可能，因为它们对人类很重要”，C选项“我们能停止向太空发射卫星或火箭吗？”是对问题的回应，且后文的“they”指代发射卫星/火箭，故选C。5. 第5空：前文列举了清理太空垃圾的方法，后文说希望各国重视，B选项“这些方法将有助于解决这个问题”承接前文的方法，衔接后文的期望，故选B。
