     With the growth of the Web, many people have come to view the Internet as a handy source of information. Yet there are limits to the depth of the data that can be mined from cyberspace.
     Ask a search engine that runs on your favorite Web browser to tell you where you can buy a red convertible in Miami for under $35,000. Such a car does exist. But getting the answer on line is a daunting task that often entails multiple searches.
     Now the Web’s creator, British-born Tim Berners-Lee, has set about solving such problems. The goal is to provide for the automatic exchange of any type of content between many kinds of software programs, applications and databases and, when appropriate, between people.
     He compares the online situation today with the way things were when the first Web sites were launched almost exactly a decade ago.  Before the Web created a Common programming language, accessing each database required users to learn a special set of internal rules, which could be quite arcane. Consequently, only computer mavens bothered to get Internet addresses.
     But after Berners-Lee developed the "hypertext" system of linking documents and other information with the now-familiar Web tags, his creation became the fastest-growing data gathering system in human history, reaching 30 million active domain names in 2001.
     Now, history is repeating itself. Berners-Lee has dubbed his new project "the semantic Web." While the coding concepts are complex, the idea behind them is simple enough. The semantic Web would allow programs to browse the Internet and trade data without any direct human intervention. In theory, that could turn all of cyberspace into a unified interactive computer.
     "The semantic Web represents a long-term goal to change and improve the way in which computers and users work together, as well as the way computers work with other computers," Berners-Lee told a Harvard graduate school seminar the other day. "Instead of searching for words, we search for concepts that tie things together."
     Berners-Lee and his programming team seek to provide "intelligent agents" the capacity to understand the underlying meaning -- the "semantics" -- of the information they roam through to make their searches more meaningful and efficient.
     The initial step is to create standards that allow users to add descriptive tags, or "metadata," to Web content, making it easier to pinpoint exactly what you’re looking for. Next, methods will need to be found to enable different programs to relate to metadata from various Web sites. Finally, programmers will be able to craft applications that infer vital facts from the ones they’ve been given.  And finding that convertible will be much easier.
Which of the following is true of the smarter Web, according to the author of this passage?
选项 A、The smarter web is theoretically accessible to the present web.
B、The smarter Web is to link all computers up more automatically.
C、The smarter Web is interactive in its powerful searching ability.
D、The smarter Web is more coded and more program-oriented,
答案C
解析 根据问题，应该看清新的网络的特点。具有更加强大快速的搜索功能，而且具有互动性。因而不是选项A所说能不能接近现有的网络。不是选项B那样将所有的电脑自动地机械地联接起来，而是智能地互动地将整个网络转变为像一台电脑一样：In theory，that could turn all of cyberspace into a unified interactive computer．也不是选项D所说的那样有更多的密码或者以软件程序为目的或者为导向的网络。
