2019年高中英语Unit3Computers单元小结教案（含解析）新人教版.docx

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.

Study author Brent Coker said, “Surfing the Internet at times helps increase an employees attention.”“People need to relax for a bit to get back their attention，” Coker said on the universitys website. “Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a days work, and as a result, increases productivity (生产效率)，” he said.According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software to block their employees from watching videos, using social networking sites or shopping online，” said Coker. “Thats not always a good idea.”However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.语篇解读：一项研究表明，员工上班时间适度使用网络可以提高生产效率。1What does the University of Melbourne study mainly show?APeople who surf the Internet are good employees.BNot everyone surfs the Internet for fun during office hours.CThe Internet is becoming more and more important in peoples life.

The market only _1_ (accept) cash, but after I put together some food, I realized I _2_ (leave) my wallet at home. While figuring out this _3_ (confuse) situation at the cashier, I heard the man behind me said, “Let me pay for you.” _4_ (hear) that, I was shocked.

He thanked me and saw me off with wet eyes.I had done this in small ways before, but this facetoface _10_ (kind) was the most moving experience Ive ever had.语篇解读：作者在市场买菜忘记带钱包，一个好心人帮他付了款，作者决定把这次善举传递下去。1accepts这里讲的是一般情况，所以用一般现在时态。2had left忘在家里是发生在realized之前的动作，故用过去完成时态。3confusing此处修饰situation，用形容词作其定语。4HearingI与hear之间是主动关系，故用现在分词。5to finddecide to do sth.意为“决定做某事”。6However根据句意可知，此处表示转折关系，故用however。7sincerely修饰谓语动词thanked应用sincere的副词形式。8but作者取了钱回去准备找那个男人，却发现他已经离开了。两句之间表示转折关系，故用but。9for作者告诉那个无家可归的人，那20美元是给他的。for在这里意为“为了”。10kindness根据语境可知，此处指这样面对面的善举是作者经历过的最感动的事情。.短文改错Nowadays iPads have become popular, educational and fun tool for both teachers and students.
