Ⅲ.阅读理解
A
When 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 they wanted it “new” or at least at a low price. 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 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 self－service is all about being free, cheap, fast and convenient. It's interesting how words change their meaning. Stealing has now become file 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 we're saving time.
What can be the worst experience on the Web? A site that charges us high prices and wastes our time.
1．What is the best title for the text?
A. The Nature of the Web
B. The Web and the Culture of “ Free”
C. Stealing and File Sharing
D. What Does the Word “ Free” Mean
答案与解析 B 依据第三段中“The Web has encouraged a belief that things can be free, or at least very cheap. ”网络上始终鼓舞一种东西是可以免费的观念，或者至少是格外廉价的。B项正确。
2．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A. Their music is not popular and is out of date.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.
答案与解析 D 依据其次段中的“The music will be totally free except that you will have to pay with your time by watching advertisements.”音乐将是完全免费的，除了你不得不占用时间观看广告来支付。由此可知公司可以通过加在音乐中的广告来挣钱。D项正确。
3．Which of the following can best describe the belief of the Web?
A. Risky behaviour. B. Stealing.
C. File sharing. D. For fun.
答案与解析 C 依据第三段中“Stealing has now become file sharing”“偷”已经变成了文件共享。C项正确。
B
A young woman sits down at the piano. She has long brown hair and a friendly face. And then she begins to sing. Her beautiful voice attracts everyone in the room. This is Norah Jones, awardwinning singer and songwriter.
Norah Jones was born on March 30, 1979, in New York City. She was the daughter of the legendary Ravi Shankar, a very famous guitar player. Her earliest musical influence came from her mother's CD collection. She began in church choirs (唱诗班) at the age of five and took piano lessons two years later.
For two years following her graduation from high school, she studied at the North Texas University majoring jazz piano. She didn't like law or literature like her other friends. In one summer holiday, she decided to take a trip to New York City. There she saw many musicians and songwriters. She was too eager to become one of them that she decided to stay and start her own career. At first, she took a job as a waitress but soon she joined in a band and became the leader vocals, and of course, played the piano. Later she signed with Blue Note Records Company. Through years of hard work, she finally succeeded in music and became famous for her beautiful songs.
