四级英语作文——电脑使用例文

As 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 computer per week. However, in 1995, the number was quadrupled, climbing up to four hours per week. In 2000, it 's astonishing that the number shot up to nineteen hours every week. This dramatic change 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 in many areas. Last but not least, prices for computers were reduced, so that more people 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. Therefore, I suggest students make reasonable use of computers.
