Section C

The Importance of Computers

電腦的重要性

Since computers were invented in the USA in the 1950s, they have become very important in many areas of work and leisure. There is no doubt that computers are very useful in technology and business. In space, computers have been used to control the speed and direction of a spaceship. With the help of computers, doctors can find diseases easily and solve other problems. For example, tiny computers which are inside patients’ bodies can keep their hearts beating normally. In factories, robots are controlled by computers that are like human brains. They can do work that is dangerous to humans. In business, computers are used to place and cancel orders. They are also making the workplace safer and better.

電腦于20世紀(jì)50年代在美國(guó)被發(fā)明，此后它在工作和娛樂(lè)的許多方面已經(jīng)變得非常重要。毋庸置疑，計(jì)算機(jī)在科技和商業(yè)領(lǐng)域非常有用。在太空領(lǐng)域，計(jì)算機(jī)被用來(lái)控制宇宙飛船的飛行速度和方向。在計(jì)算機(jī)的幫助下，醫(yī)生們能很容易地發(fā)現(xiàn)疾病并能解決其他問(wèn)題。例如，病人體內(nèi)的微型計(jì)算機(jī)能使人的心臟正常跳動(dòng)。在工廠里，由像人腦那樣的電腦控制的機(jī)器人能代替人類(lèi)做那些有危險(xiǎn)的工作。計(jì)算機(jī)在商業(yè)領(lǐng)域中被用于下訂單和取消訂單。同時(shí)，計(jì)算機(jī)使工作場(chǎng)所更安全、更好。

Since the Internet came into being, people’s lives at home have been changed, too. More and more people have personal computers that are used to play games and watch movies. Thanks to the Internet, people can do shopping and do business at home. Instead of writing letters on paper, people communicate by sending e-mails and chatting online. The whole world is connected. The Internet is making the world smaller, like a village.

自從因特網(wǎng)出現(xiàn)以來(lái)，人們家里的生活也發(fā)生了變化。越來(lái)越多的人有了個(gè)人電腦，他們用電腦來(lái)玩游戲和看電影。由于有了因特網(wǎng)，他們能在家里購(gòu)物或做生意。人們通過(guò)發(fā)送電子郵件和在線聊天的方式進(jìn)行交流，代替了用紙寫(xiě)信的。全世界被連接起來(lái)。因特網(wǎng)使世界變得更小了，就像一個(gè)村。

Computers have improved our lives, but they have brought problems, too. For instance, if we work on computers too long, we may get headaches or sore eyes. If we play computer games too much, we won’t have enough time to study or exercise. Besides, not everything we read on the Internet is true or good for us. Computers help us at work and at home, but they must be used properly.

雖然計(jì)算機(jī)改善了我們的生活，但也帶來(lái)許多問(wèn)題。例如，如果我們?cè)谟?jì)算機(jī)前工作太久，也許就會(huì)頭疼或眼睛酸澀。如果我們玩電腦游戲太多的話，那么我們就沒(méi)有足夠的時(shí)間學(xué)習(xí)和鍛煉。此外，我們?cè)谝蛱鼐W(wǎng)上讀到的東西并非都是真實(shí)的和有益的。計(jì)算機(jī)在工作和在家庭生活中都能幫助我們，但它們必須要被正確利用。
