学习使用电脑Student Use of Computers
This chart shows the increase of student use of computers from the year 2014 to 2015 As we can see, in 1990 the average number of hours a student spends on the computer per week is 2. In 2016, 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.
这张图表显示了2014至2015年学生使用电脑的增加。正如我们可以看到的，在1990个小时的平均数小时，学生在计算机上的每星期是2。2016nian，然而，一些双打和2000，增长到每周20小时。
这种变化的原因有很多。一方面，电脑可以做的事情，可能难以做到的人，让人们更容易的工作。所以，许多人求助于电脑，当他们想做的工作。另一方面，电脑变得越来越便宜了。结果，许多大学都安装在大的数字，许多家庭都买得起，因此，他们总是可以供学生使用。但是最主要的原因，我认为，是随着社会的发展，计算机的使用在几乎所有阶层的生活。那些专门从事计算机操作的人是非常需要的。如果一个学生在电脑上很好的话，他会有更多的机会得到一份工作。
许多问题也出现在学生使用电脑。一个问题是，有些学生花太多的时间坐在电脑前，因此，他们的健康影响。另一个问题是，一些学生在电脑上聊天或玩电脑游戏，浪费了很多宝贵时间。因此，建议这些学生科学和积极地使用计算机。
