第31题：AccordingtoCerf,thepurposetodesigninterplanetaryinternetisto_____.
［A］sendreal-timesciencedata
［B］communicatewithastr onauts
［C］layfoundationforfuturetechnologicaladvances
［D］commercializethetechnology
正确答案：C本题考查事实细节。［C］项是对倒数第三段的改写，layfoundationfor与preparemankindfor同义。［A］项在文章第三段首句提到，［B］项在第五段提到，但都是设计和建立星际因特网可能带来的好处，不是设计目的。［D］项在文章最后一段提到，是在说明建立星际因特网的可能性，不是设计目的。
