Whichofthefollowingisthemainpointofthetext?
[A]ThedevelopmentoftheInternet.
[B]Thepossibilityofspaceresearch.
[C]Universalinformationsuperhighway.
[D]ThetechnologicaladvancesoftheMarsmission.
正确答案:C本题考查文章主旨。本文主要介绍了星际因特网的创建,[C]项是对文章首句中taketheinformationsuperhighwaytoouterspace的改写,是全文论述的中心内容。[A]项在文章最后一段出现,是为了更好地说明星际因特网的发展。文章没有提到太空研究的可能性问题,[B]项错误。文章第九段提到,星际因特网是为未来火星探险技术进步奠定基础,这也是在说明星际因特网的重要作用,而不是纯粹论述火星探险的技术进步,所以[D]项不正确。
