问题     Some historian say that the most important contribution of Dwight Eisenhower’s presidency (总统任期) in the 1950s was the U.S. interstate highway system.

In 1983 the National Science Foundation (NSF), whose mission is to promote science, took over.
    This new NSF network【C9】________more and more institutional users, many of which had their own internal networks. For example, most universities that joined the NSF network had intra-campus computer networks. The NSF network then became a connector for thousands of other networks. As a backbone system that interconnects networks, internet was a name that fit.
    So we can see that the Internet is the wired infrastructure (基础设施) on which web messages move. It began as a military communication system, which expanded into a government-funded【C10】________research network.
    Today, the Internet is a user-financed system tying intuitions of many sorts together into an "information superhighway."

选项
答案 G
解析 名词辨义题。根据空格前的government-funded和空格后的research network可判断，此处应填入一个形容词或名词。原文第一段提到了信息高速公路如今将图书馆、公司、政府机构和个人连接起来，也就是为这些单位和个人所使用。后文中讲到了互联网的起源和发展过程。此处空格所在的段落是对互联网发展历程的总结，故填入civilian(平民)符合此处语境，凸显了因特网起初只是为军队所用，后来拓展成为民用的过程。故选G。
