Nathan Bonilla-Warford is an optometrist(验光师)in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.
Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.
He says another part of the problem is that people blink(眨眼)less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”
Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.
Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage(伤害)to the eyes.” he says.

Music tells us who we are. Because music is an expression of the beings who create it, it shows their thinking and values, as well as the social environment it came from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions. Music expresses our character and values. It gives us identity(身份,特性)as a society.
Music provides a kind of perception(感知)that cannot be acquired any other way. Science can explain how the sun rises and sets. The arts can express the emotive(情感的)meaning of the same thing. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.
The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other. They are the language through which we express our fears, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children an important way of expressing themselves such as music, we take away from them the meanings that music expresses.
Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebration, the value of peace and love.
So music education is far more necessary than people seem to realize.
小题1:What can we learn from Paragraph 1?
A.Students regard music as a way of entertainment. |
B.Students disagree with their parents on education. |
C.Students take music as an important subject. |
D.Students prefer the arts to science. |
A.compare it with rock music |
B.show music identifies a society |
C.introduce American musical traditions |
D.prove music influences people’s lifestyles |
A.explain the world in different ways |
B.explain different facts of the world |
C.express people’s feelings in different ways |
D.explain what it means to be human differently |
A.Music education is worth more attention. |
B.Music should be of top education priority. |
C.Music is really a good communication tool. |
D.Music education makes students more imaginative. |
Heavy schoolbags have been a serious 44 for a long time. But the e-schoolbag will 45 . An e-schoolbag is 46 lighter than a usual schoolbag. Perhaps, the e-schoolbag should be 47 an e-textbook. It is a small computer for students. It is as 48 as a usual book, 49 it can still have all the things for study, such as textbooks, exercise books and so on which can be made 50 chips(芯片) like stamps. The students can read the text page by page on the screen, take notes, or even send e-mails to their teachers. They only need to 51 the right chip into the e-schoolbag. Then they can use it.
Some people say 52 e-textbooks can be easily broken, while others say it is not good for eyes. But only time will tell.

When we cut down the rainforests, we destroy these forest people, too. In 1900, there were 1,000,000 forest people in the Amazon forest. In 1980, there were only 200,000.
The Yanomami live along the rivers of the rainforest in the north of Brazil. They have lived in the rainforest for about 10,000 years and they use more than 2,000 different plants for food and for medicine. But in 1988, someone found gold in their forest, and suddenly 45,000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases came to the forest with the strangers.
The Yanomami people tried to save their forest, because it was their home. But the people who wanted gold were stronger.
Many forest people try to save their forests. Chico Mendes was famous in Brazil because he wanted to keep the forest for his people. “I want the Amazon forest to help all of us-forest people Brazil, and all the Earth,” he said. A few months later, in December 1988, people who wanted to cut down the forest killed Chico Mendes.
In Borneo, people were cutting down the forest of the Penan people to sell the wood. The Penan people tried to save their rainforest. They made blockades across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time.
In Panama, the Kuna people saved their forest. They made a forest park which tourists pay to visit.
The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts(坚果) which grow on the forest trees.
小题1:The number of the people living in the Amazon forest in 1980 was _______ of that in1900.
A.half | B.one-third | C.two-fifths | D.one-fifth |
A.pick fruits and kill animals to eat |
B.use plants for food and medicine |
C.have lived there for about ten thousand years |
D.made the roads and the airports |
A.carry away the gold conveniently |
B.make people there live a better life |
C.stop spreading the new diseases |
D.develop the tourism(旅游业) there |
A.包围 | B.障碍 | C.街区 | D.通道 |
A.we need wood to build houses, so we have to cut down trees |
B.the rainforest people have done something to protect their home |
C.to humans, gold is more important than trees |
D.we mustn’t cut down any trees or kill any animals |
They were first 42 on 1980s in China, but the selling was not very good. Today, thanks 43 improvements on battery quality, the electric bikes sell well. There are now more than 100 electric bicycle producers in China and 26 million such bicycles were produced in 2011. Japan is another large 44 of such bicycles in the world with a total production reaching 381,721in 2010.
45 China is one of the largest producers of electric bicycles in the world, the 46 of its producers with mass production (大批量生产) is actually small.
Electric bicycles are still 47 in China. Time is needed for people to become familiar with them and accept them. Each bike’s price of between 2,000 yuan (US $318) and 3,000 yuan (US $477) is still 48 for ordinary citizens (民众). Although such bikes are quick, safe and 49 to operate, their batteries still have shortcomings (不足). They weigh more than 10 kilograms; their service life is 50 two years and they 51 400 yuan each.
There were more than 450 million bikes in China in 2006. If just one percent of all these bikes are replaced by electric 52 , the market will be very large. And 53 the battery is further improved and the price is 54 , many of us will not be able to keep back from 55 the latest electric bikes

A student who thinks cheating is the only way to pass a test 45 to talk with the teacher and his or her parents so they can find some better ways together. Talking about these problems and 46 them out will help feel better than cheating.
If a student gets 47 cheating, the teacher may give a “zero” on the test, send him or her to the head teacher’s office, and call his or her parents. Worse than the bad grade may be the feeling of having disappointed those people, 48 parents and teachers. A parent may worry that you are not an 49 person and a teacher might watch you more 50 the next time you’re taking a test.
There are plenty of reasons why a kid shouldn’t cheat, but some students have already cheated. If that’s you, it’s 51 too late to stop cheating. Cheating can become a habit, but a student is always able to act better and make better 52 . It might help to talk the problem over with a parent, teacher, or friend.
