高中英語作文范文:互聯(lián)網(wǎng)-The Internet

時間: 若木1 分享
  The Internet
  The Intemet was first established in 1960s. At that time, the computer was both large and expensive and the networks were unable to work well. If one of the computers broke down, the whole networks would be unable to work.
  At first, the Intemet was just used by the government. By 1970s, it had been used in universities, banks and hospitals. At the beginning of 1990s, computers became both cheaper and easier to operate. Now it is very convenient to log on the Internet.
  It is said that each day tens of millions of people log on the Internet.Sending e-mails is becoming more and more popular.
  The Internet has become the most important part of people's life.
  互聯(lián)網(wǎng)
  互聯(lián)網(wǎng)建于20世紀60年代。那時,計算機又大又貴,網(wǎng)絡(luò)不能很好地運行。如萊其中一臺機器出現(xiàn)故障,整個網(wǎng)絡(luò)就不能運行。
  起初,互聯(lián)網(wǎng)只由政府使用。到20世紀70年代,計算機已經(jīng)被用于大學(xué)、銀行和醫(yī)院。在20世紀90年代初計算機價格下降,也更便于使用了。現(xiàn)在上網(wǎng)很方便。
  據(jù)說每天有成千上萬的人上網(wǎng),發(fā)電子郵件正變得越來越流行。
  互聯(lián)網(wǎng)已成為許多人生活中最重要的一部分。
