One early problem faced by Internet users was speed. Phone lines could only transmit information at a【C4】______ rate. The development of fiber-optic (光纤) cables allowed for billions of bits of information to be received every minute. Companies like Intel developed faster microprocessors, so personal computers could process the【C5】______ signals at a more rapid rate.
In the early 1990s, the World Wide Web was developed, in large part, for【C6】______ purposes. Corporations created home pages where they could place text and graphics to sell products. Soon airline tickets, hotel【C7】______ , and even cars and homes could be purchased online. Universities【C8】______ research data on the Internet, so students could find【C9】______ information without leaving their dormitories.

【C4】
选项
答案
G
解析
形容词辨析题。本空位于冠词a和名词rate之间,因此应填入形容词修饰rate。空格所在句的前一句提到,因特网用户早期面临的一个问题是网速,也就是说早期的因特网网速很慢。本句是对前一句的进一步解释,电话线路只能以______速度传输信息。空格处应填入有“慢”含义的形容词,故答案是G)limited“有限的”。本空前冠词是a,故排除E)incoming。而除了G)limited以外的其他形容词不能修饰rate(速度),故排除。
