All over the world, libraries have begun the Herculean(巨大的) task of making faithful digital copies of the books, images and recordings that preserve the intellectual effort of mankind. For armchair scholars, the work promises to bring such a wealth of information to desktop that the present Internet may not match.
Librarians see three clear benefits to going digital. First, it helps them preserve rare and fragile objects without refusing the demands of those who wish to study them. The British Library, for example, holds the only medieval manuscript(手稿)of Beowulf in London. Only qualified scholars were allowed to see it until Kevin S. Kiernan of the University of Kentucky scanned the Manuscript with three different light sources and put the images up on the Internet for anyone to use.
A second benefit is convenience. Once books are changed to digital form, readers can find them in seconds rather than minutes. Several people can read the same book or view the same picture at the same time. Clerks are spared the chore of reshelving. And libraries could use the Internet to lend their collections to those who are unable to visit in person.
The third advantage of electronic copies is that they occupy millimeters of space on a magnetic disk rather than meters on a shelf. The cost of library buildings is increasingly high. The University of California at Berkeley recently spent $ 46 million on an underground addition to house 1.5 million books----an average cost of $30 per volume. The price of disk storage, on the contrary, has fallen to about $ 2 per 300-page publication and continues to drop.
What is the message in the first paragraph?

A.More people can read precious books.
B.The Internet provides more information.
C.Libraries are making efforts to preserve books.
D.Libraries are making digital copy of books.

Which words in the second paragraph help you to identify the supporting points?

A.three, First, for example B.benefits, manuscript, scholars
C.helps, holds, scanned D.clear, qualified, different

Which of the following is mentioned in the text as benefits of going digital?

A.Fewer staff will be required in libraries.
B.Libraries will be able to move underground.
C.Borrowers need not go to the library building.
D.Old manuscripts can be moved more easily.

How is the text organized?

A.Opinion – Description B.Message – Explanation
C.Main idea – Comparison D.Introduction – Conclusion

Winter is dangerous because it’s so difficult to know what is going to happen and accidents take place so easily. Fog can be waiting to meet you over the top of a hill. Ice might be hiding under the melting (融化) snow, waiting ahead to send you off the road. The car coming to you may suddenly slip(滑) across the road.
Rule No.1 for driving on icy roads is to drive smoothly (平稳地). Sudden movements can make a car very difficult to control. So every time you either start or stop your car, increase or reduce your speed, you must be as gentle and slow as possible. Suppose you are driving with a full cup of hot coffee on the seat next to you. Drive so that you wouldn’t spill (溅) it.
Rule No.2 is to pay attention to what might happen. The more ice there is, the further down the road you have to look. Test how long it takes to gently stop your car. Remember that you may be driving more quickly than you think. Generally, allow twice of your usual stopping distance when the road is wet, three times this distance on snow than usual, and even more on ice. Try to stay in control of your car at all time and you will not get into trouble.

A farmer had a cow.
A farmer had a cow. He took very good care of this cow and one day when it was ill, he was very worried. He telephoned the vet.
“What’s the problem?” The vet asked him when he arrived.
“My cow’s ill,” the farmer said. “I don’t know what's the matter with her. She’s lying down and won’t eat. She’s making a strange noise.”
The vet looked over the cow. "She’s certainly ill," he said, "and she needs to take some very strong medicine."
He took a bottle out of his box, put two pills into his hand and said, "Give her these. The pills should make her better."
“How should I give them to her?” the farmer asked.
The vet gave him a tube (管子)and said, "Put this tube in her mouth, then put the pills in the tube and blow(吹). That’ll make it."
The next day the vet came to the farm again. The farmer was sitting outside his house and looked more worried.
“How’s your cow?” the vet asked.

For better eyesight, doctors advise limiting the hours of screen time and encourage having enough eye resting time.
However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia(近视). An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.
The research team found that the prevalence(流行)of myopia among children in Sydney was lower than children in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore.
Indoor and outdoor sports activities both make the eyes focus on more distant objects, which prevents the eyes from changing shape. But outdoor activities may better help avoid myopia than indoor sports activities.
Jane Gwiazda, who does research in sight problems, says: “Natural light is good for eye growth. And extra vitamin D from the sun might contribute to eye growth.”
Many doctors suggest that every child get its first eye test done when he/she is about two and half years old, and even if his/her sight seems perfect.
It is necessary for myopic children to wear glasses to prevent headaches, trouble reading or injuries. It is also important that schools invite doctors to test their students’ eyes.
If that is not possible, school teachers should at least encourage parents and children to have regular eye examinations and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors.
What’s the aim of the study by the Australian research team ?

A.To find the reasons for myopia.
B.To find the ways to treat myopia.
C.To prove the bad effects of myopia.
D.To prove the prevalence of myopia.

Why are there fewer children with myopia in Sydney than in Singapore ?

A.Because Sydney children watch less TV.
B.Because Sydney children have more eye resting time.
C.Because Sydney children use computers less.
D.Because Sydney children do more outdoor sports.

What conclusion can we draw from the passage ?

A.Sydney children don’t study hard.
B.Singapore children do few exercises.
C.Outdoor activities do more good to eyes.
D.Room light does harm to children’s eyes.

Which of the following statements is TRUE ?

A.Children should have eye tests as soon as they reach school age.
B.Doing outdoor activities with no glasses is good for myopia children.
C.Focusing on distant objects can help the eyes keep their original shape.
D.Children should limit their time in the sun in order to protect their eyes.

For the most part, you are probably only exposed to the music that is played on your favorite radio stations and TV shows, music Web sites, or the music that your friends and family members enjoy. While you probably know a lot about your favorite type of music, it can be a rewarding experience to enlarge your horizons(眼界), discovering artists and types of music that you’re not familiar with. Who knows, you might discover you like certain types of music you never even considered.
Have you ever wondered about the history and influences of your favorite types of music ? For example, did you know that rock ‘n’ roll originated(起源)from the blues, and that the blues began as a form of musical expression for African Americans during slavery(奴隶制度)?Did you know that most hip-hop is heavily influenced by early rhythm blues and jazz ?
There are many fun ways to learn about different musical styles and their historical roots. For example, if you like hip-hop, listen to some of your favorite CDs and take note of the samples the performers used to create the songs. There is a possibility that the artist used parts of older songs to create the music. You can go to the library or online to learn more about the artists and listen to more of their music by checking out CDs from the library or downloading songs online for a small fee.
You can learn so much about culture and history just by paying attention to different types of music and what is being expressed in the songs. There are so many different styles of music to learn about, and you owe(欠)it to yourself to make an effort to listen to and learn about them.
