Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23.It was the third shark attack along the coast of Australia's largest city in a month.
The 15-year-old boy and his father were in the water off Avalon，on Sydney's northern beaches，around dawn when he was attacked.The city's beaches are packed with locals and tourists during the summer months.
“The father heard a scream and turned to see his son thrashing(激烈扭动)about in the water，”the police said.“Fortunately，the shark swam away and the boy was helped to the shore by his father.”
Lifesaving Club spokesman Nick Miller said，“It got him around the top of his left leg and the father came and dragged him out of water.”He said the boy was bleeding heavily when he was brought to the shore.“There was a lot of pain，as you can imagine.”The teenager was airlifted to hospital for treatment for leg injuries.
Police said the bites “cut through to the bone”，but the boy did not appear to have sustained any fractures (骨折)．He was in a stable condition now.
Several beaches were closed after the attack.Water police and lifeguards were searching for the shark，while the police hoped to identify its species by the shape of the bite marks.But they said it was too early to say what type of shark attacked the boy.“I don't even know if he saw it，”Miller said.
Many shark species live in the waters off Sydney's beaches，but attacks on humans are still relatively rare.However，there were two attacks on successive days earlier this month，one on a navy diver in Sydney harbor，not far from the famous Opera House，and the other on a surfer at the city's world-famous Bondi beach.
Fishermen say shark numbers are on the rise.There is a ban on commercial fishing in the harbor，which has increased fish stocks.Marine experts also claim environmental protection has created a cleaner environment，attracting sharks closer to the shore as they chase fish.Many shark species，including the Great White—the man-eaters made famous in Steven Spielberg's Jaws—are protected in Australian waters.The report mainly tells us ________.

School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to learn some facts or a formula by heart. It is actually quiet easy to learn a certain fact in history or a formula(公式) in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientist, such as Einstein, Newton and Galileo, didn’t get everything from school. But they were all so successful and invented so many things for men. They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.According to the passage, a good teacher should be one who is to_________.
| A．help his students to gain a good memory. |
| B．train his students’ ability to learn |
| C．teach his students everything he knows |
| D．have his students studying long hours |
If a student want to learn better, the most important thing for him to do is_______.
| A．to learn all the useful facts and formula by heart |
| B．to do everything as his teacher have said in class |
| C．to absorb (吸收) as much knowledge from his teacher as possible |
| D．to think more while he is studying |
The main reason for the success of the great scientists is that________.
| A．the teachers who had taught them were all experienced. |
| B．they used to work and study without a moment’s rest. |
| C．they had received more schooling than other people |
| D．they know how to study and worked hard |
What’s the good advice the writer gives us?
| A．We can learn better without teachers |
| B．We should do more asking and thinking while studying |
| C．We should pay enough attention to classroom |
| D．Book knowledge is little use |
Our surrounding(周围) is being polluted faster than nature and man’s present efforts can’t prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are always ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from countryside to cities, eager for the benefit of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going—and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society. Man can’t prevent the world from being polluted mainly because .
| A．many man-made materials |
| B．more cars, trucks and buses |
| C．more people and more industry |
| D．more cities |
People crowd into the cities because_________.
| A．they want very much to find well-paid jobs |
| B．they eager for the achievement of our modern society |
| C．they have become tired of their homeland |
| D．they have a strong wish to become industrial workers |
The story about the airline pilot tells us that_________.
| A．man knows where the society is going |
| B．people do not welcome the rapid development of modern society |
| C．man can do little about the problem of pollution |
| D．the writer is worried about the future of our society |
What does the writer really want to say in this passage?
| A．With the development of technology, pollution has become a serious problem. |
| B．Lower the speed of development to stop pollution. |
| C．It’s time we did something to reduce pollution. |
| D．As industry is growing fast, pollution is the natural result. |
When you want to go shopping, you’d better decide how much money you can spend on new clothes.
Think about the kind of clothes you really need. Then look for those clothes you really need. Then look for those clothes on sale.
There are labels(标签) inside all new clothes. The labels tell you how to take care of your clothes. The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash in cold water. The label on a coat may say “dry clean only”, for washing may ruin this coat. If you do as the directions(说明) on the label, you can keep your clothes looking their best for a long time.
Many clothes today must be dry cleaned. Dry cleaning is expensive. When buying new clothes, check to see if they will need to be dry cleaned. You will save money if you buy clothes that can be washed.
You can save money if you buy clothes that are well done. Well-made clothes last longer. They look good even after they have been washed many times. Clothes that cost more money are not necessarily(不一定) better made. They do not always fit better. Sometimes less expensive clothes look and fit better than more expensive clothes.The label inside the clothes tell you ．
| A．how to keep them looking their best. |
B．how to save money. |

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."
