问题 The" wired cities" in the United States were not constructed, ______.
In Para. 3, the concept of "wired cities" is revived because ______.

选项 A、personal computers become easily available to more people
B、the Internet has found extensive applications
C、the number of online consumers and companies is on the rise
D、e-malls have replaced letters as the dominant message of communication

答案A

解析 由题干的Para.3,the concept of "wired cities" is revived定位到原文第三段第一句First. computers, have become more powerful, cheaper, smaller, easier to use(although they still have a long way to go on this front )and more widely distributed, especially within businesses and especially in the US.推断题。此题涉及的是“电缆城市”概念复苏(revive)的原因,文中谈到了两点,一是个人电脑的普及 (第三段),二是Internet的发展及广泛运用(第四、五段)。A)在第三段第一句提到,因此正确。[避错]第四、五段提到了Internet的应用,如academic network,surfing,cyber-commerce等,因此B)不符合题意;最后一段最后一句"the e-mail population reached ’critical mass’ in about the mid-1990s"表明使用电子邮件的人达到了极大的数量,可知C)也不符合题意;也不能依此得出D)“电子邮件取代信件成为主要的信息交流方式”的结论,因此D)不是其中的原因,故也不正确。
