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.

What do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportu­nity to make money.
Eight students from No 2 Secondary School Attached to East China Normal Uni­versity started a virtual company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction a week a­go. The company, which has recruited around 20 student staff members, has earned over 2000 yuan in the past three months.
"We donated part of the money to a poor school in the countryside of Anhui Province. It's great to realize our ideal of ‘spreading love and culture with seeds’ after many tests and lots of hard work," said Senior 2 Shi Chen, CEO of the compa­ny.
Just like any other company, Shi's didn't develop smoothly. Shi and her young colleagues used to sell fresh flowers and old books, and later found seeds might be something that their company could engage in. They bought seeds of various plants and flowers at low prices from a local farm and sold them in schools or on streets. The creative students also made accessories and pictures with different seeds.
With little business knowledge, the students had to learn new skills as the lead­ers of different departments, such as public relations (PR), sales and marketing. They persuaded a joint Sino-French company near their school to give them training in business management. They also asked some local businessmen to act as their consul­tants.
"They helped us overcome our shyness. We also learned quite a lot of business theory. I found communication skills and teamwork are very important for my job," said Senior 1 Qian Yifei.
The 16-year-old was elected as PR manager thanks to her talent for speaking. She is also in charge of after sales service, dealing with complaints and providing suggestions.
As the head of the company, CEO Shi has a lot more to think about. First of all, she has to learn how to make her colleagues work efficiently as the company only opens at weekends due to all their studies. So she established a system to evaluate every one's performance, in terms of punctuality, efficiency, profits knowledge and so on.
"It makes the company more formal," she said.
59. What is the purpose of opening the company?
A. To earn money for their education fees.
B. To spread love and culture with seeds.
C. To see whether they can open a company.
D. To collect money to open a Hope School.
60. At a campus auction a week ago, they ________ .
A. sold 28 green plants with different flowers
B. sold 28 seeds pasted with different pictures
C. sold 28 pictures pasted with different seeds
D. sold 28 flowers pasted with different pictures
61. According to Qian Yifei, what matters most in dealing with public relations?
A. Communication skills and teamwork.
B. Creative and critical thinking.
C. Educational background.
D. Business theories.
62. What does the word "it" (in the last paragraph) refer to?
A. Selling seeds.
B. To have a person as CEO.
C. Every colleague’s performance.
D. To make her colleagues work efficiently.

B. The company is over-night successful.
C. The company gets a lot of help from others.
D. The company sells old books and fresh flowers.

“Mum, what does it mean when someone tells you that they have a skeleton (骨骼) in the closet (衣橱)?” Jessica asked. “A skeleton in the closet?” her mother paused thoughtfully. “Well, it's something that you would rather not have anyone else know about. For example, if in the past, someone in Dad's family had been arrested for stealing a horse, it would be 'a skeleton in his family's closet'. He really wouldn't want any neighbor to know about it.”
“Why pick on my family?” Jessica's father said with anger. “Your family history isn't so good, you know. Wasn't your great-great-grandfather a prisoner who was transported to Australia for his crimes?”“Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.”“Gosh, sorry I asked. I think I understand now,” Jessica cut in before things grew worse.
After dinner, the house was very quiet. Jessica's parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica's closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor. Jessica's mother sank in a faint (晕倒), waking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
“What happened? Where am I?” she asked. “You just destroyed the school's skeleton, Mum,” explained Jessica. “I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad.” Jessica looked in amazement as her parents began to laugh madly. “They're both crazy,” she thought.

We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people think that craft no longer exists.
One of the ways these people wrongly support their view is by pointing to 100-year-old homes which are still solid, and arguing that it is the craftsmanship that is responsible for their durability. “Homes in those days were well-built,” they say. No doubt these homes were well-built, but what these people have done is mix up the quality of material used in the house with the quality of the craftsmanship.
Homes today could be built to last just as long as those old homes if people were willing or able to pay the price. For example, most people can no longer afford solid oak stairways, although they were once fairly common in older homes. Nor can they afford the high labor cost of employing a carpenter to build the stairway. Yet if someone can pay the high cost, there are still plenty of carpenters around able to make those stairways. And not only would these carpenters know how to build them, they would probably do a better job than carpenters of old.
One thing the modern carpenter has which enables him to do a better job is much more advanced tools. Such tools as laser beams and powerplanes help them lay out a house better and make more precision cuts on the wood. Also, it is not uncommon say more to find carpenters with college degrees and carpenters with a solid knowledge of mathematics, which would enable them to deal with more difficult house designs.
The problem of modern quality, then, really boils down to the problem of material, for the modern carpenter is just as able to produce craftsmanship as the carpenter of fifty years ago, but only if given proper material.
【小题1】 Compared to the carpenters in the past, modern carpenters are           .

A.more successfulB.more learned
C.more imaginativeD.more hardworking
【小题2】 What does the underlined work “they” (paragraph 2) refer to?
A.Carpenters who are fond of oak stairways.
B.Carpenters who have college degrees.
C.People who think highly of carpenters of old.
D.People who think that modern material is of low quality.
【小题3】What does the third paragraph mainly discuss?
A.People in the past preferred to use oak to build stairways.
B.It is now expensive to employ a carpenter.
C.Modern houses last as long as the old ones.
D.Good carpenters still exist in modern times.
【小题4】 What would be the best title for the text?
A.Is Craft Dead?B.Craft, Back to Life?
C.History of CraftsmanshipD.Carpenters Today and Yesterday
