Instead, he has been told to ‎ wait another two years, until he is 18.‎ ‎ The 16-year-old boy works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David’s firm puts two new games on the home market each month.‎ But David’s biggest headache is what to do with his money. In spite of his salary, made by inventing new programs within a quite short period of time, the bonus payments and profit-sharing (奖金和分红), he cannot drive a car, get some money from a bank to buy a house, or get credit cards.‎ He lives with his parents in their house in Liverpool, where his father is a bus driver. His firm has to pay ￡‎150 a month in taxi fares to get him the five miles to work and back every day because David cannot drive.‎ David got his job with the firm a year after leaving school with six 0-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said.‎ ‎“I suppose 35,000 pounds sounds a lot but actually that’s not good enough. I hope it will come to more than that this year.” He spends some of his money on records and clothes, and gives his mother 20 pounds a week. But most of his spare time is spent working.‎ ‎“Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I know what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.”‎ David added, “I would like to earn a million and I suppose early retirement (退休) is a possibility. You never know when the market might disappear.”‎ ‎1. Why is David different from other young people of his age?‎ A. He earns a very high salary.‎ B. He has not a job.‎ C. He does not go out much.‎ D. He lives at home with his parents.‎ ‎2. David’s greatest problem is ____________.‎ A. making the banks treat him as a grown-up B. inventing computer games C. spending his salary D. learning to drive ‎ ‎3. He was hired by the firm because ____________.‎ A. he had worked in a computer shop B. he had written some computer programs C. he worked very hard D. he had learned to use computers at school ‎4. He left school after taking six 0-levels because ____________.‎ A. he did not enjoy school B. he wanted to work with computers and staying at school did not help him C. he was afraid of getting too old to start computing D. he wanted to earn a lot of money ‎5. Why does David think he might retire early?‎ A. One has to be young to write computer programs.‎ B. He wants to stop working when he is a millionaire.‎ C. He thinks computer games might not always sell so well.‎ D. He thinks his firm might go bad.‎ 第三课时 Grammar 预习导学 语法呈现 ‎1. I _____________in office and homes since the 1970s.‎ ‎2.

But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.‎ ‎ It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization.‎ ‎ Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.‎ ‎ Does all this mean environmental concerns(环境问题) have been ‎ forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. I guess people believe that the problem is taken care of, because of recycling(回收利用), said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity.‎ ‎ The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.‎ ‎31. The growing demand for paper in recent years is largely due to ____.‎ A. the rapid development of small businesses B. the opening up of new markets C. the printing of high quality copies D. the increased use of the Internet ‎32. Environmentalists believe one possible way of dealing with the paper situation is ____.‎ A. to encourage printing more quality documents B. to develop new printers using recycled paper C. to find new materials for making paper D. to plant more fast-growing trees ‎33. Hewlett-Packard Co. has decided to develop new technologies ‎ because ____.‎ A. people are concerned about the environment B. printers in many offices are working overtime C. small companies need more hard copies D. they see a growing market for printers ‎34. What would be the best title for the text?‎ A. Computers and Printers.‎ B. E-mail and the Business World.‎ C. Internet Revolution and Environment.‎ D. Modern Technology and New Markets.‎ B ‎ Your friend might be in Australia or maybe just down the road, but they are all just a few clicks away. Life has changed for millions of teenagers across the world who now make friends online. Whether you use chat room, QQ, MSN or ICQ, you are part of virtual community.‎ ‎ “I rarely talk with my parents or grandparents, but I talk a lot with my old friends on QQ,” said Fox’s Shadow, the online nickname used by a Senior 2 girl in China. “Eight percent of my classmates use QQ after school.”‎ ‎ QQ is the biggest messaging service in China. A record 4 million people use it one Saturday night in October, according to Tencent,‎ ‎ the company which developed QQ.‎ ‎ And Fox’s Shadow might well have been one of them. “I log in on Friday nights, and Saturdays or Sundays when I feel bored. I usually spend about 10 hours chatting online every week,” she said. “But I rarely talk with strangers, especially boys or men.”‎ ‎ Even though she likes chatting, she is careful about making friends with strangers online. “You don’t know who you’re talking to. You should always be careful about who you trust online.”‎ ‎ Many people would like to meet offline when they feel they have got to know someone very well. Fox’s Shadow once met one of her online friends face to face. It was a girl who was a comic fan like herself and they went to a comic show together.‎ ‎ However, not all teenagers have been so fortunate. At the beginning of this year, a 17-year-old girl in Liaoning Province was raped after meeting a friend she had found on QQ.‎ ‎ A 16-year-old Beijing boy, known online as Bart Simon, dislikes QQ users. “I used to chat on QQ, but I found that most people were talking nonsense.” he said. Now he chats online in English, using MSN. “I only chat online because I’ve got friends in Japan, the US and Singapore,” he said, “I want to learn more about foreign cultures.” But he spends little time chatting as he sees it as a waste of time and money.‎ ‎ “If you are really addicted to it sometimes you just can’t concentrate in class,” he said. “And the friends in your real life are always more important than those so-called friends you meet online.”‎ ‎35. How many messaging services have been mentioned in the passage?‎ ‎ A. 2 B. ‎3 C. 4 D. 5‎ ‎36.What’s the meaning of the phrase “log in” in the fourth paragraph?‎ ‎ A. Take off. B. Get online. ‎ ‎ C.

I’m very glad to be here today to give you a short speech about computers and our life. I hope you will like it.‎ With recent economic development, computers have become more and more important in our life. First, we can work more efficiently. Second, we can go online and get connected with our ‎ friends. Third, if we need any information, we can use the computer to look for it on the Internet. It is convenient and easy.‎ ‎ A coin has two sides, though. Computers have some bad effects as well. For example, some students have wasted a lot of valuable study time playing games. Also, people who use computers too much can become near-sighted.‎ ‎ In short, I hold the view that we should avoid the bad effects they may bring, while making good use of computers.‎
