The Importance of Computers

电脑的重要性

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.

电脑于20世纪50年代在美国被发明，此后它在工作和娱乐的许多方面已经变得非常重要。毋庸置疑，计算机在科技和商业领域非常有用。在太空领域，计算机被用来控制宇宙飞船的飞行速度和方向。在计算机的帮助下，医生们能很容易地发现疾病并能解决其他问题。例如，病人体内的微型计算机能使人的心脏正常跳动。在工厂里，由像人脑那样的电脑控制的机器人能代替人类做那些有危险的工作。计算机在商业领域中被用于下订单和取消订单。同时，计算机使工作场所更安全、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.

自从因特网出现以来，人们家里的生活也发生了变化。越来越多的人有了个人电脑，他们用电脑来玩游戏和看电影。由于有了因特网，他们能在家里购物或做生意。人们通过发送电子邮件和在线聊天的方式进行交流，代替了用纸写信的。全世界被连接起来。因特网使世界变得更小了，就像一个村。

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.

虽然计算机改善了我们的生活，但也带来许多问题。例如，如果我们在计算机前工作太久，也许就会头疼或眼睛酸涩。如果我们玩电脑游戏太多的话，那么我们就没有足够的时间学习和锻炼。此外，我们在因特网上读到的东西并非都是真实的和有益的。计算机在工作和在家庭生活中都能帮助我们，但它们必须要被正确利用。
