學(xué)生如何使用計(jì)算機(jī)范文
1． 上圖所示為1990年(每周使用電腦不到2小時(shí))、1995年(每周4小時(shí))、2000年(每周20個(gè)小時(shí))某校大學(xué)生使用計(jì)算機(jī)的情況，請(qǐng)描述其變化。
2． 請(qǐng)說(shuō)明發(fā)生這些變化的原因（可從計(jì)算機(jī)的用途、價(jià)格或社會(huì)發(fā)展等方面加以說(shuō)明）。
3． 你認(rèn)為目前大學(xué)生在計(jì)算機(jī)使用中有什么困難或問(wèn)題。
這是一篇圖表附提綱式作文，1991年6月的四、六級(jí)考試曾經(jīng)使用過(guò)此種命題方式，是四、六級(jí)考試歷史上第二次使用這種命題方式，雖然考生對(duì)此題型不太適應(yīng)，但卻代表了未來(lái)四、六級(jí)作文命題的發(fā)展方向。第一段，利用圖表（只在此段中描述圖表）描述使用計(jì)算機(jī)的情況，突出在使用計(jì)算機(jī)小時(shí)數(shù)上的變化。第二段，指出造成這種變化的三個(gè)主要原因：首先，社會(huì)的發(fā)展帶來(lái)了經(jīng)濟(jì)的繁榮；其次，計(jì)算機(jī)在各個(gè)領(lǐng)域的廣泛應(yīng)用；最后，通過(guò)調(diào)整價(jià)格，普通百姓也能買(mǎi)得起計(jì)算機(jī)了。第三段，計(jì)算機(jī)在為學(xué)生帶來(lái)益處的同時(shí)也造成了一些問(wèn)題：首先，由于在計(jì)算機(jī)上花的時(shí)間太多而荒廢了學(xué)業(yè)；其次，學(xué)生的身心健康受到了一定程度的傷害。
參考范文：
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 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， XXX 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。
