Jan Tchamani, an English teacher in Birmingham, UK, suddenly developed a serious illness and had to quit her job. At age 50, she found herself out of work and stuck at home with only her computer to keep her company. After a while, she discovered that surfing the Internet could help her feel less lonely and bored. She could listen to music, watch films, play games, and explore the world. She also joined an online group wh ere she could talk about her problems and get support and advice from others. She realised that one of the greatest benefits of the Internet was its ability to remove the distance that usually exists between people.英国伯明翰的一位英语教师简•夏曼尼突然得了重病，因此不得不辞职。

Unit 3 WHO AM I?Over time I have been changed quite a lot. I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearlytwo hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could “think” logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my “artificial intelligence”. In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a “universal machine”to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large asa room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC(personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn’t believe it! But I was always so lonely standing there by myself, until in the early 1960sthey gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.Since the 1970s many new applications have been found for me. I have become very importantin communication, finance and trade. I have also been put into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sentto explore the Moon and Mars. Anyhow, my goal is to provide humans with a life of high quality. Iam now truly filled with happiness that I am a devoted friend and helper of the human race!ANDY-THE ANDROIDI’m part of an android football team. About once a year we are allowed to get together to play a game of football. I’m as big as a human. In fact, I look like one too. On the football team I’m a striker so I have to be able to run very fast. My computer chips help me to move and think like a human. For example, I have learned to signal to my teammates in computer language to give methe ball when I am open and have a good shot for a goal.My first football competition was in Nagoya, Japan several years ago. Last year our team wentto Seattle, Washington in the USA. We won second place. Personally, I think the team that wonfirst place cheated. They had developed a new type of program just before the competition. So we need to encourage our programmer to improve our intelligence too. We are determined to create an even better system. In a way our programmer is like our coach. She programs us with all the possible moves she has seen while watching human games. Then she prepares reliable moves to use if a new situation arises. In this way I can make up new moves using my “artificial intelligence”. I would really like to play against a human team, for I have been programmed to act just like them. After all, with the help of my electronic brain which never forgets anything, usingmy intelligence is what I’m all about!。

必修3 unit1Festivals and celebrationsFestivals and celebrations of all kinds have been held everywhere since ancient times.Most ancient festivals would celebrate the end of cold weather,planting in spring and harvest in autumn.Sometimes celebrate would be held after hunters had caught animals.At that time people would starve if food was difficult to find,especially during the cold winter months.Today’s festivals have many origins ,some religious,some seasonal, and some for special people or events.Festivals of the DeadSome festivals are held to honour the dead or to satisfy the ancestors,who might return either to help or to do harm.For the Japanese festival.Obon,people should go to clean graves and light incense in memory of their ancestors.They also light lamps and play music because they think that this will lead the ancestors back to earth.In Mexico,people celebrate the Day of the Dead in early November.On this important feast day,people eat food in the shape of skulls and cakes with”bones”on them.T hey offer food,flowers and gifts to the dead.The Western holiday Halloween also had its origin in old beliefs about the return of the spirits of dead people. It is now a childr en’s festival,when they can dress up and to to their neighbours’ homes to ask for sweets.If the neighbours do not give any sweets,the children might play a trick on them.Festivals to Honour PeopleFestivals can also be held to honour famous people .The Dragon Boat Festival in China honours the famous ancient poet, Qu Yuan.In the USA Columbus Day is in memory of the arrival of Christopher Columbus in New World.India has a national festival on October 2 to honour Mohandas Gandhi,the leader who helped gain India’s independence from Britain.Harvest FestivalsHarvest and Thanksgiving festivals can be very happy events.People are grateful because their food is gathered for the winter and the agricultural work is over.In European countries,people will usually decorate churches and town halls with flowers and fruit,and will get together to have meals.Some people might win awards for their farm produce,like the biggest watermelon or the most handsome rooster.China and Japan have mid-autumn festivals,when people admire the moon and in China,enjoy mooncakes.Spring FestivalsThe most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring.At the Spring Festival in China,people eat dumplings,fish and meat and may give children lucky money in red paper.There are dragon dances and carnivals,and families celebrate the Lunar New Year together.Some Western countries have very exciting carnivals,which take place forty days before Easter,usually in February.These carnivals might include parades,dancing in the streets day and night,loud music and colourful clothing of all kinds.Easter is an important religious and social festival for Christians around the world.It celebrates the return of Jesus from the dead and the coming of spring and new life.Japan’s Cherry Blossom Festival happens a little later.The country, covered with cherry tree flowers, looks as thought it is covered with pink snow.People love to get together to eat , drink and have fun with each other.Festivals let us enjoy life,be proud of our customs and forget our work for a little while。

Unit 3 THE INTERNETSTRONGER TOGETHER: HOW WE HAVE BEEN CHANGED BY THE INTERNETMuch has been written about the wonders of the World Wide Web. There are countless articles telling us how the Internet has made our life more convenient. We no longer have to wait in line or carry cash around when we go shopping. We can get the most updated information from large databases. We can download software, documents, and images whenever we need them. But the Internet has done much more for people than simply make life more convenient. People’s lives have been changed by online communities and social networks.Jan Tchamani, an English teacher in Birmingham, UK, suddenlydeveloped a serious illness and had to quit her job. At age 50. she found herself out of work and stuck at home with only her computer to keep her company. After a while, she discovered that surfing the Internet could help her feel less lonely and bored. She could listen to music, watch films, play games, and explore the world. She also joined an online group where she could talk about her problems and get support and advice from others. She realised that one of the greatest benefits of the Internet was its ability to remove the distance that actually exists between people.She was so inspired by the people she met online that she decided to start an IT club to teacher older people how to use computers and the Internet. She and her friends now organise events and collect money for private teachers. Many people have been helped by the club. A 59-year-old man learnt how to apply for work online and found a great job. Now that he works and can take care of himself, his daughter has time to study atuniversity. A 61-year-old woman who was living alone has started a small online company together with two friends. She no longer feels lonely, and her company has become quite successful.Jan has started taking online classes to learn more about how to use the Internet to make society better. She believes that it is highly important to bridge the digital divide and make sure that everyone has access to the Internet and knows how to use technology. Her next goal is to start a charity website to raise money for children in poor countries.Jan’s life has been greatly improved by the Internet. “when you go through tough times, you meet others who are facing similar challenges.” Jan says. “Thinking about other people’s situation inspired me to offer help.”Reading and writingToday I thought I’d blog about a question that has been asked many times-how do you stay safe online and avoid bad experiences on the Internet? I’m not an expert, but many years as a blogger have taught me a thing or two.First of all, there’s the golden rule of the Internet: if you see orread something that makes you feel uncomfortable, leave the site immediately. Don’t post comments or click on anything. Second, protect you privacy. Don’t give out your address or phone number. Someone might use the information to steal your identity. Identity theft is a common and serious problem. Third, be polite. Being online is no excuse for being rude, and you don’t want to become a target for a troll or cyberbully. A troll is a person who posts comments or questions in order to stir up trouble online. Trolls often use several false names so that they can stay on a site. A cyberbully uses the Internet to be mean to others. Like a troll, a cyberbully will also write something mean but it is usually directed at particular people. He or she may also post embarrassing photos and information about these people. However, the more polite you are, the less likely it is you will be attacked.Have you had any bad experiences online, or do you have some good advice for staying safe? Post your comments below!。
