Technological changes brought dramatic new options to Americans living in the 1990s. During this decade new forms of entertainment, commerce, research, and communication became commonplace in the U. S. The driving force behind much of this change was a( n)【C1】______ popularly known as the Internet.
The Internet was developed during the 1970s by the Department of Defense. In the case of an attack, military advisers suggested the【C2】______ of being able to operate one computer from another terminal- In the early days, the Internet was used mainly by scientists to communicate with other scientists. The Internet【C3】______ under government control until 1984.
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. Companies soon discovered that work could be done at home and【C10】______ online, so a whole new class of telecommuters began to earn a living from home offices unshaven and wearing pajamas (睡衣).
A) advantage I) maintained
B) commercial J) occupations
C) conservation K) posted
D) equipped L) remained
E) incoming M) reservations
F) innovation N) submitted
G) limited O) valuable H) local [br] 【C9】
选项
答案
O
解析
形容词辨析题。本空位于不可数名词information之前,应填入形容词作定语。由句意可知,学生足不出户就可以在网上查到学校发布的研究数据,而这些数据对他们来说肯定是有用的,因此应填入O)valuable“有价值的,珍贵的”。备选形容词中,还剩下H)local,学生在网上不可能只找到当地的信息,语义太片面,故排除。
