Student Use of Computers
Students tend to use computers more and more nowadays. Reading this chart, we can find that the average number of hours a student spends on the computer per week has increased sharply. In 1990, it had less than 2 hours, and in 1995, it increased to almost 4 hours, and in 2000, the number soared① to 20 hours.
Obviously computers are becoming more and more popular. There are several reasons for this. First, computers facilitate② us in more aspects of life. Also, the fast development of the Internet enlarges our demands for using computers. We can easily contact with friends in remote③ places through the Internet. Besides, the prices of computers are getting lower and lower, which enables more students to purchase them.
However, there still exist some problems, such as, poor quality, out-of-date④ designs and so on. And how to balance the time between using computers and studying is also a serious problem.
Anyhow⑤, we will benefit a lot from computers as long as we use them properly.
【注释】
①soar: 飞涨，暴涨
②facilitate: 使……变得随意马虎；促进……
③remote: 迢遥的；远方的
④out-of-date: 过期的
⑤anyhow：不管若何；总之
【点评】
这是一篇根据中文提要展开的图表式解释文。这种题型在近几年的大学英语四级考试中常常涌现。
本文首先依照提示哀求对已给出的数据进行剖析得出：1990年到2000年学平生均每周花在打算机上的韶光呈飞速上升趋势，然后剖析该征象形成的缘故原由是电脑方便了我们的生活，功能快捷、便于联系，及价格下跌。末了指出存在的一些问题。同时告诫学生要处理好利用打算机和课程学习的关系。
本文笔墨朴实，构造严密，措辞简洁流畅。
