【小题5】to
【小题6】however
【小题7】that
【小题8】completely
【小题9】itself
【小题10】Besides/Moreover/Furthermore. - 试题分析：文章大意：如果地球上的人口仍以当前的增长率增长的话，最终地球上将没有足够的资源供给生命生长。面对人口急剧地增长，资源日益地短缺的困境，可能的途径就是其他星球寻找空间，比如金星。
【小题1】left.考查非谓语动词，leave与resources是动宾关系，应用leave的过去分词形式left做后置定语。
【小题2】will have used.考查将来完成时。由时间状语by the middle of the 21st century可知要用将来完成时态。
【小题3】it.考查形式宾语及固定搭配。make it +adj “使…处于…状态”。
【小题4】none.考查代词及固定搭配。But表转折，到其他地方找开放空间是重要，但是目前太阳系中除了地球没有其他星球可以支持生命。 none of“没有一个”
【小题5】to.考查固定搭配。the solution to“…的解决办法”，注意to在这是介词。
【小题6】however.考查连词。前一句说没有其他星球可以支持生命，结合后文知金星上还是有供给生命的水分。故这里缺少表示转折的连词。however表转折。
【小题7】that.考查宾语从句的引导词。该句是宾语从句，其引导词为that。
【小题8】completely.考查副词。completely修饰形容词exhausted,表示地球资源完全枯竭。
【小题9】itself.考查反身代词。地球本身 Earth itself.
【小题10】Besides/Moreover/Furthermore.考查副词。.由语境知这里缺少个并列词，只有副词可单独运用，bessides,moreover,furthermore“而且，此外”，表并列关系。
