In all the world’s cultures, people sing, play instruments, and celebrate with music. It plays such an important role in our lives that all fields focus on its study, including one looking at the biology of music. Experts find that because of the way our brains process music, learning to play an instrument or just listening to music can have a wide range of benefits.
Music education has received a lot of attention. Learning to play an instrument can help children improve math, science, and language skills. One study in Canada tracked children’s IQ scores for nine months, discovering that children who studied music had the biggest test score improvements. The secret may lie in the way reading music and playing notes use several areas of the brain, increasing our ability to learn school subjects. For example, reading notes improves spatial(空间的) reasoning skills, which are helpful in solving math problems like fractions(分数).
Music is also used for medical purposes, such as the treatment of diseases which affect memories. The secret lies in the way the brain processes music. One area near the forehead, the medical prefrontal cortex, connects music with memories stored in two other areas: the amygdale and hippocampus. That’s why an old song can remind you of something that happened years ago. For patients suffering from diseases like Alzheimer’s, listening to music can help unlock buried memories by strengthening musical pathways to memories.
With the evidence of music’s benefits, it’s no wonder some countries make music study a part of their education system. People are recognizing that more than just a form of entertainment, music is also great for the brain.Scientists are studying music because .

Imagine you're at a party full of strangers. You're nervous. Who are these people? How do you start a conversation? Fortunately, you've get a thing that sends out energy at tiny chips in everyone's name tag (标签). The chips send back name, job, hobbies, and the time available for meeting - whatever. Making new friends becomes simple.
This hasn't quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet's skin, even under your own skin. Passive RFID tags have no energy source - batteries because they do not need it. The energy comes from the reader, a scanning device (装置), that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient's medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person ) section and pays for the bill with the wave of an arm.
Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could he put every where and send information in smart network that would make ordinary life simpler.
RFID tags are a small part of this phenomenon. "The world is going to he a loosely coupled set of individual small devices, connected wirelessly." Predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers, Accompanied by how many biscuits.
When Marconi invented radio, he thought it would be used for ship - to - shore communication, not for pop music. Who knows how RFID and related technologies will be used in the future. Here's a wild guess: Not for buying milk.

Over the last 70 years, researchers have been studying happy and unhappy people and finally found out ten factors that make a difference. Our feelings of well-being at any moment are determined to a certain degree by genes. However, of all the factors, wealth and age are the top two.
Money can buy a degree of happiness. But once you can afford to feed, clothe and house yourself, each extra dollar makes less and less difference.
Researchers find that, on average, wealthier people are happier. But the link between money and happiness is complex. In the past half-century, average income has sharply increased in developed countries, yet happiness levels have remained almost the same. Once your basic needs are met, money only seems to increase happiness if you have more than your friends, neighbors and colleagues.
"Dollars buy status, and status makes people feel better," conclude some experts, which helps explain why people who can seek status in other ways－scientists or actors, for example－may happily accept relatively poorly-paid jobs.
In a research, Professor Alex Michalos found that the people whose desire－not just for money, but for friends, family, job, health－rose furthest beyond what they already had, tended to be less happy than those who felt a smaller gap(差距). Indeed, the size of the gap predicted happiness about five times better than income alone. "The gap measures just blow away the only measures of income." Says Michalos.
Another factor that has to do with happiness is age. Old age may not be so bad. "Given all the problems of aging, how could the elderly be more satisfied?" asks Professor Laura Carstensen.
In one survey, Carstensen interviewed 184 people between the ages of 18 and 94, and asked them to fill out an emotions questionnaire. She found that old people reported positive emotions just as often as young people, but negative emotions much less often.
Why are old people happier? Some scientists suggest older people may expect life to be harder and learn to live with it, or they're more realistic about their goals, only setting ones that they know they can achieve. But Carstensen thinks that with times running out, older people have learned to focus on things that make them happy and let go of those that don't.
"People realize not only what they have, but also that what they have cannot last forever," she says. "A goodbye kiss to a husband or wife at the age of 85, for example, may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20."

Almost every child is scared of something, from monsters in the cupboard to dogs in the park. But the fact that such fears are common and normal doesn’t mean they can be taken lightly. Kids experience fears and phobias(恐惧症) much more strongly than adults. And the influence of the fear can be physical as well as psychological(心理的). It can build up so they almost seem scared of everything－a kind of childhood anxiety. Dr. Creswell says: “Your child may always seem to expect the worst to happen and lack confidence in his or her ability to deal with any challenge.” So don’t make the same old mistake of treating them as if they’re silly for being a “scaredy cat”. Handling the fears is essential.
Children can be born nervous and, if you have such a baby, you’ll tend to prevent them from getting worried. So if they fear dogs, you’ll keep them away from dogs, but in fact that can just confirm to the child that dogs are scary. What is worse, keeping your child away from what they fear can turn that feeling into a phobia. Instead, you should encourage them to get in touch with the thing they fear, in a safe and supportive environment. Dr. Andy Field, a researcher of childhood fears, says: “You shouldn’t force, for example, a dog anxious child to go up to a dog. But you can approach it yourself, show them there is nothing to be afraid of, stroke(抚摸) it, and talk about the dog being friendly. Once your child dares to stroke a dog－one that’s good with children, of course－then you should encourage them to carry on until they feel calmer, and reward them for ‘being brave’.”Children’s fears are usually taken lightly because __________.
| A．they will not develop into phobias |
| B．their influence is psychological |
| C．they exist widely in the world |
| D．they will disappear gradually |
If we fail to help children to overcome fears, they will ___________.
| A．make the same old mistake |
| B．overcome them by themselves |
| C．experience the worst of things |
| D．grow up lacking self confidence |
According to Dr. Andy Field, if a child is afraid of a cat, parents should __________.
| A．tell the child not to be afraid of it |
| B．show the child how to approach it |
| C．keep the child away from it |
| D．ask the child to stroke it |
How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?
In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.
Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces, They are taller, to reach higher branches. They have shorter tusks（象牙）, and most importantly, longer trunks to dig for water in riverbeds.
Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families. They drink only every 3 –4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders – they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Young elephants may even eat the dung（粪便）of the female leader of a group when facing food shortage.
During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine（尿液）to make them muddy!
As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.The underlined part in Paragraph 2 means “”.
| A．remains in the African countries |
| B．drinks 120 liters of water a day |
| C．manages to live in desert areas |
| D．eats 150 kilograms of food daily |
Desert elephants are called careful feeders because they _________.
| A．rarely ruin trees |
| B．drink only every 3-4 days |
| C．search for food in large groups |
| D．protect food sources for their young |

Karen, grown up in a very traditional family in the western United States, maintained high moral（道德的）standards throughout her youth. In 1984, at the age of 23, she married Bill. They
were blessed with two children, a boy and a girl.
By 1991 their love had deepened, and they were happy. Later that year, Bill developed a white spot on his tongue. He visited a doctor.
One day shortly after that, Bill called Karen to sit beside him. He said with tears in his eyes that he loved her and wanted to live forever with her. The doctor suspected that he had been infected with HIV, the virus that leads to AIDS.
The family was tested, Bill and Karen's results were positive. Bill had become infected before he met Karen then he passed the virus on to Karen. The children's results were negative. Within three years. Bill was dead, "I don't know how to express what it is like to watch the once handsome man you love and intend to live with forever dying slowly. I cried many nights. He died three months short of ten years of our marriage," says Karen. Though a doctor told Karen that she would soon follow her husband into death, she is still alive. The infection has progressed to the early stages of AIDS.
Karen is hut one of about 30 million people now living with HIV/AIDS, a figure larger than the combined populations of Australia. Ireland and Paraguay. According to one UN report, Africa has 21 million of these victims. By the turn of the century that number could reach 40 million and the disease will bring on the greatest disaster in human history. Of the world's sexually active adults aged 15 to 49. 1 in 100 has already been infected with HIV. Of these, only 1 in 10 realizes that he or she is infected. In some parts of Africa, 25 percent of the adults are infected.
Since the beginning of the spread of AIDS in1981, about 11.7 million people have died of it. It is roughly calculated that in 1997 alone, about 2.3 million people died of it. Nevertheless, there are fresh reasons for optimism in the battle against AIDS. During the past few years, there has been a drop in new AIDS cases in wealthy nations. In addition, promising drugs hold out hope of better health and longer life.
