A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.
Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

The pupils of the remote Beau-Roc primary school in Haiti are chanting (singing the same words again and again).One of them plays a guitar made from an empty oil tin.Their headmistress, Emile Jean-Noel, is one of the few women school headteachers in the country.
Today, over 70% of Haitian population live without proper food, water, schools, or housing. To reduce the hunger that prevents learning and to encourage parents to send their children to school, meals are provided by the World Food Programme.
"We are so cut off that we have many difficulties," comments Emile, adding that finding chalk, school books and other materials is practically impossible.Emile tries to encourage people around her to make use of available resources.Her efforts are bearing fruit.One of her successes was convincing local women to contribute to their children' s schooling and increase their income by selling embroidery(刺绣) and other handicrafts.
Recent political instability(不稳定)has meant that the country has not invested (投资) in education for ten years.Only 44% of children go to school and less than half of them finish primary school. Less than a third of these children go on to secondary school.In rural areas it is not rare to find 17 and 18 year olds in primary school- Beau-Roc has only 4 teachers for 260 pupils.Emile works constantly to improve her pupils' environment.Under her direction, a local worker is now constructing a store house for the food delivered regularly by the WFP.
Not only is Emile' s salary small, but she receives it irregularly.For her, transport is a real headache.She lives five kilometers away and has to take the tap tap, a privately-owned bus, costing more than she can afford.
"The decision to be a rural teacher in Haiti should not be taken lightly" , Emile comments. "With all the sacrifices and risks it requires, only
those who are really cut out for teaching
should do it." However, Emile loves her job."I always feel at home with the children and, because the parents understand what I'm doing, I try to give my best."

We are all busy talking about and using the Internet, but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.
At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers had become cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient.
Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.

Snow-melting Agent
A heavy snow can kill pests and this means a good harvest next year.This will bring as well as trouble to urbanites.
On Nov.16,2003,a cold air current brought a heavy snow to Beijing.To prevent traffic jams,related government departments mobilized people to clear off snow on streets.
One of the most effective ways to clear off snow on roads is to scatter snow-melting agent on the roads.The major component of the snow-melting agent is salt.The snow-melting agent can make snow stop from freezing,make it easier to clear off the road,and allow traffic to flow smoothly.But it also brings about some hidden dangers.In the spring of 2003,over 300 000 trees in Beijing urban districts died.After analyzing soil around these trees,experts discovered that the salt content of these soils was 392 times higher than normal.Where did the excessive salt come from?After investigating,forestry experts found that when clearing snow in the winter,people usually heap snow containing snow-melting agent at trees’ roots,and that when the snow melts,this agent penetrates the soil and increases its salt content.The snow-melting agent indirectly killed the trees.
Statistics show that during a heavy snow in 2002,over 1000 tons of snow-melting agent was scatterred on streets in Beijing.Snow water containing a large amount of snow-melting agent got into the soil through sewers.
In addition,salt in the snow-melting agent can expedite the corrosion of steel bars in concrete buildings and cause the concrete to crack and peel,shortening the life of roads.
Scientists and government officials are required to solve traffic problems caused by heavy snows as soon as possible and at the same time try to reduce the negative effects of the snow-melting agent.This is a difficult problem placed before them.Related authorities have framed some local criteria to regulate the production and use of snow-melting agents.
Now,more harmless snow-melting agents are being developed.Now that even snow-melting agents that meet today’s criteria must still be used carefully,we have to rely more on our manpower and machines to clear off snow.
This year,in addition to using snow-melting agents,Beijing will use a large number of snow vehicles to clear snow on roads.In more places,citizens are mobilized to clear snow with their hands.This may be a test of a city’s civilization level.

Teresa was born in Yugoslavia on August 27,1910. Her parents were Albanians(阿尔巴尼亚人) and member of the Roman Catholic Church. When she was seven years old, her father was murdered. She decided not to be filled with hate because of this tragedy(悲剧). Instead, she would seek a life of love. This ambition led her to Ireland where she became a nun(修女) at the age of eighteen.
After only one year of training, she was sent to India to teach in a school called Loretto House, where the students were mostly from rich Indian families. After 15 years there, she left her duties as a teacher to “follow Christ into the slums(贫民窟).” Her heart led her away from the rich to the needs of the poor. She was then 36 years old.
Teresa no longer was affiliated(隶属) with the Irish nuns who sent her to Loreto House but worked independently. However, her work was recognised by the Pope in Rome for she still was a nun. He allowed her to set up her own group, which was called the Missionaries of Charity(仁爱传教修女会).
She no longer dressed as a nun in the European or Irish tradition. Instead, she put on a sari, the local dress of the Indian people. At first, people were sceptical(怀疑的) about her motives. Soon, they realised she was really interested in loving poor people, even those who were dying and had no chance of survival.
Soon, other Indian people began to spare time to help Mother Teresa. She had taught everyone that the poor and dying people need love most of all.
In 1979, she won the Nobel Peace Prize.
