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 man's 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.
在这部分，你被允许30分钟写一个关于这个专题的学生使用计算机的组成。你应该写在下面的图表：鉴于纲要至少有120字的组成 和基地上图所示为1990年，1995年，2000年某校大学生使用计算机的情况，请描述其变化。1。请说明发生这些过程的原因（可从计算机的用途 ，价格或社会发展等方面加以说明）; 2。你认为目前大学生在计算机使用中有什么困难或问题？学生使用计算机，这图显示了学生使用的增加 计算机从1990年到2000年。正如我们可以看到，在1990年时，学生平均每周上的计算机花费是2。然而在1995年的数目增加一倍，并于2000年， 飙到每周20小时。有很多这种变化的原因。首先，计算机可以做许多事情洛尔，可能难以做到的人，使人们的工作变得更加容易。因此，许多 人转而求助于电脑当他们想有自己的工作要做。其次，电脑越来越便宜与日俱增。因此，许多大学都安装了许多人，许多家庭买得起的，因此 ，他们总是给学生使用。但首要的原因，我认为是，随着社会的发展，计算机在ahnost使用的所有阶层。那些谁在操作计算机专业急需。如果 学生在计算机好，机会就会更大让他找到一份工作。许多问题也出现在学生使用计算机。一个问题是，有些学生花太多时间在电脑前坐着，结 果，他们的bealth受到影响。另一个问题是，一些学生聊天或玩了很长时间的电脑游戏，浪费了宝贵的时间。因此，建议这些学生做的，是计 算机科学和积极利用。#p#分页标题#e#
