范文1Student Use of ComputersThere has been a tremendous growth in the student use of computers since 1990. The past 12 years has witnessed a sharp increase in the hours students spend on computer per week from 3.6 to 12.To account for this phenomenon, people have come up with various reasons listed below. To begin with, computers can help us accomplish many tasks, including both work and study. We used to do homework on paper while now we could just finish it with computer and e-mail to teachers. What’s more, computers are getting increasingly cheaper and more college students can afford it.Disadvantages also accompany with the wide use of computers. Many college students may be addicted to playing computer games and neglect their study. We should strike a balance between using computer and study itself.Student Use of ComputerSince1990, there has been tremendous growth in the use of computers by students. While in 1990, the average number of hours a student spent on the computer was about one hour per week, this number grew to nearly four hours per week by 1995, and to approximately 20 hours per week by the year 2000.This significant growth in the use of computers by students in the 1990’s can be attributed to several factors,including widespread usage, lower prices, and technological and social developments. Nowadays, computers are widely used by students for word processing, book keeping, multimedia presentations, and access to the Internet for both research and communications. Additionally, since 1990, due to competition and technological advances, computer hardware and software prices, as well as Internet usage charges have dropped significantly. Finally, technological developments and changes in social habits in the 1990’s have played a major role in this tremendous growth in the use of com puters. Today’s society relies heavily on computers for immediate access to the news and for entertainment, including, listening to music, watching movies and sport events, and playing computer games.While computers are of great assistance to the students, and therefore, are indispensable tools, they also pose some challenges. The biggest challenge that many students face is discipline in the use of this powerful device. That is, students need to have the discipline of not allowing themselves to be lured by the entertaining aspects of this wonderful tool—aspects that can result in addiction to computer games or viewing of undesirable material on the Internet. That is to say, students need to use this powerful tool with great wisdom!范文3Student Use of ComputersAs can be seen from the chart, in 1990, the use of computers was not popular yet, with the university student spending merely an average of one hour on the computer per week. However, in 1995, the number of hours was quadrupled, climbing up to four hours per week. In 2000, after a lapse of only five years, it was astonishing to find that the number shot up to nineteen hours every week.This dramatic change in the average number of hours the student spent on the computer per week took place chiefly for three reasons. In the first place, as the society developed, national economy became prosperous, bringing about the popularity of computers. In the second place, the use of computers went far beyond typing words, making them indispensable not only to secretaries but also to people engaged in other areas. Last but not least, prices for computers were reduced, so much so that common people with a modest income could afford them.It is true that students have benefited from spending more and more time on the computer, but problems have also arisen. Some students indulge themselves in computer games, refusing to concentrate on their studies, while many other students’ health has been damaged as a result of too much exposure to computers.Student Use of ComputersThis 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 lot 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 almost 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 health 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.范文5Student Use of ComputersThe chart shows the average number of hours a student spends on the computer per week. It can be seen from the chart that in 1990 the average number of hours a student spent on computers was around 2 hours per week. Five years later in 1995, the number was almost 4 hours a week. By the year 2000 as many as 18 hours were used every week.A number of reasons could be given for the tremendous increase in the use of computers. The practical value of computers has been gradually recognized. At first, a computer was nothing more than an expensive typewriter. Later people found it could process pictures, music, sound as well as words. The latest development of web has made computers necessary to those who hope to obtain 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 of their own seem to be spending too much time playing computer games, which is a waste of computers.Changes in China’s Legal Holidays2.请说明发生这些变化的原因3.得出结论Changes in China’s Legal HolidaysIt can be seen from the chart that great changes have took place in china’s legal holidays between 1999 and 2008. Especially, some Chinese traditional festivals come into the family of legal holidays. (Why are there such great changes during the past nine years?)In my opinion, three possible reasons contribute to it. First of all, with the “holiday economy” coming into vogue, huge flows of population bring extreme pressure to traffic and lodging, which also causes much trouble to us common people. Thus, “golden weeks” must be adjusted. Secondly, traditional cultures and folk-custom of our nation should be highlighted. Traditional festivals must be respected and carried forward. (For example, the Dragon Boat Festival has a history of more than two thousand years and many Chinese conventions are included here.) Therefore, it is reasonable to accept some traditional festivals as legal holidays. Finally, to add some legal holidays embodies the consideration of our government. It helps to construct a harmonious country.In a word, changes in china’s legal holidays are a rational improvement and great progress. On the one hand, it can spread the spirit of our Chinese nation and enhance Chinese culture. On the other hand, the public interest is protected.。
