When we look at the sky and see a bright light moving quickly across it or coming towards the earth, we talk about seeing a “shooting star” or a “falling star”. These moving lights are not, in fact, stars at all. They are small pieces of matter from outer space, which burn up as they enter the Earth’s atmosphere. The correct name of them is meteoroids. Any pieces that make it to the Earth’s surface without completely burning up are known as meteorites. A meteor is actually the name given to the light we see when a meteoroid is burning up.
When a meteorite hits the Earth at speeds between 11 and 72 kilometers a second, it can do amazing damage. A very large meteorite could knock the earth out of its orbit. If this happened, all life on Earth would probably become extinct(灭绝). The path we follow around the Sun would change and as a result the Earth would become either much hotter or much colder. This change in temperature would affect sea levels and the amount of water in rivers. There would either be huge floods, which would cover most of the land with water, or the oceans would dry up and there would be a drought, which means a long period of time without rain. Either way, nothing could survive. If a large meteorite landed in the sea it would almost certainly cause tsunamis, which would race towards the land, destroying everything in their paths.
Although it is unlikely the Earth will be struck by a meteorite large enough to do that kind of damage, there is evidence of fairly large meteorites hitting the Earth in the past. In 1908 a large area of forest in Tunguska, Siberia was destroyed by a meteorite that came apart just before it hit the ground. The moon, however, has about three billion craters陨石坑caused by meteorites impacting影响 its surface. The reason more meteorites have reached the surface of the moon than the surface of the Earth is that the moon does not have enough atmosphere for the meteorites to burn up in. some of the meteorites that have reached the Earth’s surface have done considerable damage. Some scientists believe it was a change of climate caused by meteorites hitting the Earth that resulted in the extinction of the dinosaurs and other large prehistoric animals.
Scientists are especially interested in meteorites because they contain information about the solar system. It is widely believed by scientists that most meteorites are produced by collisions(碰撞) between asteroids (small planets). These collisions probably happened many billions of years ago. This means the physical and chemical structure of a meteorite can give scientists information about the early days of the universe.The story is about ___.

“BANG!” the door caused a reverberation (回声). It was just standing there, with Father standing on one side, and I on the other side.
We were both in great anger.“Never set foot in this house again!” stormed Father.With tears welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining rather desolately(凄凉的).I wandered aimlessly.
A young father who held a child in his arms walked past me.I felt as if I saw my childhood from another space: happy and harmonious.
But now…I don’t know whether it is because I have grown up or because dad is getting old.We differ in our ways of thinking.He always imposes his opinions and codes of behavior on me.Whenever I do something wrong, he never admits it.We are just like two people coming from two different worlds.It feels like there is an iron door between us that can never be opened.
I wandered the streets, without a destination in mind.My heart was frozen on this hot summer night.As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company.When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.
In fact, it was nothing.Perhaps, dad was throwing away some of his old stamps.Perhaps he thought they were useless.I never had the courage to tell him that I liked collecting stamps.I can’t stand his outrageous(蛮横的) words: “ I can throw you away, let alone these old papers.”
All the lights were off except father’s.
Dad was always like this.Maybe he didn’t know how to express himself.After shouting at me, he never showed any mercy or any moments of regret.After an argument he has the habit of creeping coming up quietly in my sleep and then tucking (盖好) me underneath the covers.
This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature.
The light was still on.“Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been.At last, I decided to open the door.As soon as I opened the door, tears ran down my cheeks.I suddenly realized that the iron door that I had imagined between us did not exist at all.Love – is second to none.

Pretoria, South Africa – Hundreds of swimmers play in the water along a South Africa beach. Suddenly a huge shark appears off shore and heads for the bathers. Before it can get close to the swimmers, the shark, for some mysterious reason, starts swimming parallel to the beach. Then it turns away from the shore and heads out to sea, leaving the swimmers untouched.
Such a scene will soon become common along shark-in-fasted (鲨鱼成群的) shores. An electrical engineer from the University of Pretoria has developed an electrical system that repels (击退) sharks by controlling their movements. Confused by this action, the sharks end up turning away from the beach.
In this unusual shark-repellent method, an insulated (绝缘的) cable is buried on the bottom of the sea around a beach where people swim. When an electric current is sent through the cable, an electric field is produced in the water above the cable.
When shark swims into the electric field, nerve cells just below the shark' s skin will sense the field. The electricity produces a reflex (反射作用) action in the shark' s muscles, causing the dangerous animal to swim parallel to the cable. Confused by increasing loss of control of its muscles, the shark suddenly changes its direction and heads seaward, away from the electric field.
In a test of the invisible new shark-repellent system, a cable was placed around a beach in St. Lucia, an island around the beach a long time ago to keep sharks away from swimmers, and a net was left in place during the experiment.
When the electric field was left on for more than a year and a half, no sharks were found in the net. However, when the power was turned off,89 sharks ended up in the net.
Using the electric-wall method instead of net to protect bathers would avoid the needless death of many sharks, said biologists. Currently, thousands of sharks die each year when they become trapped in protective nets that surround holiday resorts in Africa and Australia. About 10 to 15 humans are killed by sharks annually.
1.Why doesn' t the shark attack the swimmers according to the passage?
A.Because there are so many swimmers in the water.
B.Because the shark isn’t so hungry as to eat the swimmers.
C.Because of some mysterious power from the heaven.
D.Because there is an invisible electric field confusing the shark.
2.An electrical engineer from the University of Pretoria has developed __ .
A.a protective net
B.a new shark-repellent system
C.the electric field
D.an insulated cable
3.An electric field is produced in the water above the cable .
A.only when a shark swims into the electric field
B.only when an insulated cable is buried on the bottom of the sea around a beach where people swim
C.only when an electric current is sent through the cable
D.only when the sharks are trapped in protective nets
4.Which of the following is NOT TRUE according to the passage?
A.Protective nets had been fixed earlier than the new shark-repellent system.
B.The new shark – repellent system will probably replace the protective nets.
C.Thousands of sharks have died each year since this new system was put into use.
D.Using the electric-wall instead of nets would avoid the needless death of many sharks.

Coca Cola is an American icon – and sometimes seen as a symbol of the country’s economic right. But one of the world’s famous companies will play a different role during the 2008 Olympic Games: promoting Oriental (东方的) culture to the world.
The man who is in charge of the project couldn’t be more suited for the job. The American has lived in the country for about 15 years, speaks fluent Chinese, and considers Beijing his hometown. David Brooks, vice-president and general manager of the Olympics Project Group of Coca Cola China, who has lived in the country for more than a decade, said: "We are working very hard to create a lot of special different kinds of items that are very Oriental in character and have a strong Oriental identity. "There is a lot of curiosity around the world about the country and about Oriental culture. So, we think we also have a role and opportunity to show people so many things."
Coca Cola has launched its logo(标识) with the Beijing Games, featuring kites and lucky clouds, traditional elements in the Oriental culture. Brooks considers it a good start. "We are doing a lot of similar programs, and in the next 570 days or so, as we count down to the Games, you will see more examples with strong Oriental spirit and identity."
He certainly has a sense of history. "The Olympic spirit, which is an ancient spirit from over 2,000 years ago, is alive. It still lives through the Olympic Games in the idea of balancing the body and mind, and doing the best," said Brooks, who has been to three Games. "It's like a big family celebrating together. I think all the members of my team and I feel it is a special honor to be involved in the Games."

Making an advertisement for television often costs more than a movie. For example, a two – hour movie costs $6 million to make. A TV commercial can cost more than $6 000 a second. And that does not include cost of paying for air time. Which is more valuable, the program or the ad? In terms of money – and making money is what television is all about – the commercial is by far the more important.
Research, market testing, talent, time and money —— all come together to make us want to buy a product. No matter how bad we think a commercial is, it works. The sales of Charm went up once the ads began. TV commercials actually buy their way into our head. We, in turn, buy the product.
And the ads work because so much time and attention are given to them. Here are some rules of commercial ad making. If you want to get the low middle – class buyer, make sure the announcer has a though, manly voice. Put some people in the ad who work with their hands. If you want to sell to upper – class audience, make sure that the house, the furniture, and the hair style are the types that the group identifies(认同)with. If you want the buyer feel superior to the character selling the product, then make that person so stupid or silly that everyone will feel great about himself or herself.
We laugh at commercials. We don’t think we pay that much attention to them. But evidence shows we are kidding ourselves. The making of a commercial that costs so much money is not kid stuff. It’s big, big business. And it’s telling us what to think , what we need, and what to buy. To put simply, the TV commercial is a form of brainwashing.

Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers.
Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, there were inquiries into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however, the new rules came too late to protect the people who died or two became seriously ill.
Today many governments have special departments which protect customers and workers. In the U.S., for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work, and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness, but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.
