There are two interesting news items in the paper a few years ago. One was about a man who received a bill from the telephone company for $999,999—for three months！The other was about a man who received $2,000 for doing nothing.The connection between the two news items is simple：computers—the best invention of the twentieth century. The telephone bill came from a computer which made a big mistake：the man’s bill was only $23.36.The other item was not so interesting. A man walked into the unguarded computer room of a large packaged food company and expertly programmed the computer to pay him $2,000 a month for raw meat which he “supplied” to the company. Of course he never sent the meat，but he certainly received the money. The computer wrote out a bill，and even “signed (署名) it. It was only a random(随便的) check that uncovered the trick. It could be happening in thousands of other companies all over the world.Computers are not the magic workers that some people say they are. They make mistakes，they are sometimes slower than human beings and they are easily fooled. The US used to conscript(征兵) people with the help of a computer. The army sent out a card，which had to be filled in and sent back. It was easy to avoid being called up (应征入伍) simply by spreading candle -wax on the card. The computer couldn’t read the card，and did nothing with it.It’s in our everyday life that computers cause many problems. Let’s get back to using people instead of computers，before a mistake that we can’t put right. 11．In the first paragraph we know ________.A．the paper is telling a lieB．the first sentence is the topic sentenceC．the two news items made people surprisedD．if a man did nothing at all for the telephone company，he would still get $2,000 12．The man was given $2,000 because ________.A．the computer made a big mistakeB．he worked very hardC．he programmed the computer to pay him so much for raw meatD．his work was very difficult to do and the pay was certainly high13．The main idea of the second paragraph is ________.A．computers are magic workersB．computers can do anything as manC．computers can write out a bill and even “sign” itD．computers sometimes also make big mistakes14．The writer’s main idea is that ________.A．we’d better use people instead of computers in our everyday lifeB．we should not use computers because they always make mistakesC．computers are widely used in our everyday lifeD．if we want to work fast，don’t use computersBWhen the recent research was analyzed (分析), it was found that a lot of people wanted free pictures or free music from the Web. If it couldn't be free, then theywanted it “new” or at least at a low p rice. It seems that 70 percent of people aged 16 to 24 download music online but only 1 in 40 tracks are bought legally.Thus, some companies are planning to give all of their music away for free. The music will be totally free except that you will have to pay with your time by watching advertisements. This will be perfect for those who have lots of time but little money.The Web has encouraged a belief (信念) that things can be free, or at least very cheap. It seems that everyone is looking for a good deal on the Web. The desire for free objects is part of the nature of the Web because the Web is about self­service and self­service is all about being free, cheap, fast and convenient(方便的). It's interesting how words change their meaning. Stealing has now become file (文档) sharing, but it's not really stealing, is it?Free is a funny word. We all know that very little is really for free. If we go searching on the Web for free music, we know —or should know —that there are risks involved. However, it doesn't matter. We still want free things, or at least the sense that we're getting a real bargain and that at a minimum(最小量) we're saving time.What can be the worst experience on the Web? A site that charges us high prices and wastes our time.15．What is the best title for the text?A. The Nature of the WebB. The Web and the Culture of “Free”C. Stealing andD. What Does the Word “Free” Mean16．Why do some companies “sell” their music for free?A. Their music is not popular and is out of date.B. Most people have lots of time but little money.C. Their music can't be sold new or for a low price.D. They can earn money from the advertisements added in the music.17．Which of the following can best describe the belief of the Web?A. Bad behavior.B. Stealing.C. Music sharing.D. For fun.CElizabeth Freeman was born in about 1742 to African American parents who wereslaves. At the age of six months she was acquired, along with her sister, by John Ashley, a wealthy Massachusetts slaveholders. She became kno wn as “Mumbet” or “Mum Bett.”For nearly 30 years Mumbet served the Ashley family. One day, Ashley’s wife tried to hit Mumbet’s sister with a stick. Mumbet protectedher sister and took the blow instead. Angry, she left the house and refused to come back. When the Ashleys tried to make her return, Mumbet turned to a lawyer, Theodore Sedgewick.

She refused and instead went to work for Segdewick. Mumbet died in 1829, but her spirit lived on in her family for many years. One of her great-grandchildren was W.E.B. Du Bois, one of the founder of the NAACP, and an important writer and spokesperson for African American civil rights.Mumbet’s tombstone still stands in the Massachusetts cemetery where she was buried. It reads, in part, “She was born a slave and remained a slave for nearly thirty years.
