资源描述
Unit 3 ComputersIn a way computers can be considered a technological revolution. Because they have “artificial intelligence”, they can simplify difficult sums, “think” logically and solve any difficult mathematical problem. With the development of the network, computers have become very important in communication, finance and trade, and people all over the world can share their knowledge with others through the World Wide Web. Nowadays boys and girls use their mobile phones to surf the Internet. In order to explore the moon and Mars, computers have already been put into space rockets. In a word, computers can nearly deal with most problems in life. With the help of computers, the goal of human race will be turned into reality.However, just as a saying goes, “Every coin has two sides.” Personally, if you dont use computers properly, something uncomfortable will happen. For example, computer games programmed by operators are so wonderful that a lot of young people love them very much. They even play the games day and night without going to school. As a result, they failed in their lessons. Sometimes if you download something, viruses which can make your computer break down will arise.Anyhow, if you have a computer, your life will be filled with happiness.在某种程度上电脑可以被看作是一次技术革命。因为电脑有“人工智能”,因此它们能够简化复杂的算数题,逻辑“思考”,解决任何数学难题。随着网络的发展,电脑已经在通讯、金融和贸易方面变得非常重要。世界各地的人们可以通过万维网与其他人分享他们的知识。如今少男少女们用移动手机上网冲浪。为了探索月球和火星,已经在太空火箭上安装上了电脑。总之,电脑几乎能够处理生活中的大部分难题。在电脑的帮助下,人类的目标将会变成现实。然而,正如一句谚语所说的:凡事都有利弊。我个人认为,如果你使用电脑不恰当,不如意的事情就会发生。例如,由电脑操作员编程的电脑游戏是那样奇妙,以至于很多年轻人非常喜欢它们。他们甚至日日夜夜地玩电脑游戏,不去上学。结果,他们荒废了学业。有时如果你下载一些东西,能够导致电脑瘫痪的病毒就会出现。不管怎样,如果你有一台电脑,你的生活就会充满幸福。加餐练(一)完形阅读组合练.完形填空In the middle of town lived an old man.
