This chart shows the increase of student use of computers from the year 1990 to 2000. As we can see, in 1990 the average number of hours a student spends on the computer per week is 2. In 1995, however, the number doubles and in 2000, it soars to 20 hours per week.
There are many causes for this change. For one thing, computers can do a lor of things that may be difficult for man to do, making mans work easier. So, many people turn to computers for help when they want to have their job done. For another, computers are becoming cheaper day by day. As a result, many universities install them in large numbers and many families can afford to buy one, consequently, they are always available for the students to use. But the prime reason, I think, is that with the development of society, computers are used in ahnost all walks of life. Those who are specialized in operating computers are badly needed. If a student is good at computer, chances will be greater for him to get a job.
Many problems also arise in students use of computers. One problem is that some students spend too much time sitting in front of their computers, as a result, their bealth is affected. The other problem is that some students chat or play video games for a long time on computers, wasting a lot of their precious time. So it is suggested that these students make a scientific and positive use of the computers.
