选项
答案 The graph shows the average number of hours a student spends on the computer per week. It can be seen from the graph that in 1990 the average number was around one hour per week and five years later in 1995 ,the number was almost 4 hours a week. By the year 2000 as many as 20 hours were used every week. A number of reasons could be given for the tremendous increase in the use of computers. Nowadays, a computer was nothing more than an expensive typewriter. It could process pictures, music, sound as well as words. The latest development of web has made computers so necessary to those who hope to get information more quickly. And college students are among those who are eager to learn and to learn fast. While computers are getting faster and smaller, their prices are coming down ,which means they are more affordable to college students. Computers are powerful and convenient. Yet, considering the increasing number of college students, more computers need to be installed at the college computer centers. On the other hand, students who can use computers at their own will seem to be spending too many hours playing computer games, which is a waste of computers.
