Running like the wind, roaring (咆哮) like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China.
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.
The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950's, there were over 4000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species.
Sixtysix of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves.
“Breeding has damaged the quality of the species”, said Pei Enle, deputy director of the Shanghai Zoo.
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.
“South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”, said Lu Jun, office director of the National Wildlife Research and Development Center. “We tried in Fujian Province, but it was not successful as there was not a complete ecochain(生物链) and there was a lack of space.”
The tigers should return to China in 2007 when the reservations in Fujian are ready.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
| A．Because it has lost its natural instincts. |
| B．Because there is not a complete ecochain. |
| C．Because there is no space for it. |
| D．Because uncontrolled hunting has destroyed its natural living conditions. |
How is the programme of sending several tigers to South Africa getting on?
| A．Its effect still remains to be seen. |
| B．Two tigers can already compete with their wild cousins. |
| C．Some of the tigers are already on the road to recovering their natural skills. |
| D．The tigers should be able to recover their instincts completely by 2007. |
By saying “but they are nothing like their wild cousins”, the writer means that________.
| A．they are no longer feared by other wild animals |
| B．they don't know how to hunt or kill |
| C．a complete change has resulted in the species because of breeding |
| D．to reintroduce them into the wild has become an urgent task |
What is the purpose of sending young tigers to South Africa?
| A．To help the tigers recover their ability to live in the wild. |
| B．To provide them with a better environment. |
| C．To get the tigers to go on a tour. |
| D．To find a complete ecochain for them. |
Most people agree that the direct, assertive(过分自信的) American personality is a virtue, but it sometimes surprises foreigners. In many cultures, respect for older people or those in positions of authority keeps others from expressing their true feelings. But in the U.S, children often argue with their parents, students may disagree with their teachers, and citizens may express opposition to the actions of the government. If the soup has a fly in it or the meat is too tough to chew, the diner can complain to the waiter, if the boss makes a mistake, an employee will politely point it out.
Some straight talk about the American character must include the admission that Americans have their faults. The extremely competitive nature of Americans is probably their worst fault. Of course, competition isn’t always bad. As a matter of fact, it promotes excellence by encouraging individuals and businesses to try to do their best. But the desire to get ahead of others sometimes causes people to do things that are unkind and even dishonest. Also, Americans admire what is practical, fast, efficient, and fresh. Sometimes they fail to understand and appreciate practices that have greater respect for more traditional, leisurely ways of doing things. On the other hand, people from other cultures may dislike the practical, challenging American lifestyle.
Despite culture differences, most foreigners give Americans credit for their virtues. Americans are generally viewed as friendly, adaptable, energetic, and kindhearted. Most newcomers to the U.S. like Americans, and the feeling is usually mutual. Perhaps the greatest American virtue is a deep interest in new ideas and new people. In a nation of immigrants, the foreigner does not remain an outsider for long.
In order to show the respect for older people,. .
| A．people from some other cultures will always express their true feeling |
| B．people from some other cultures may sometimes hide their true feeling |
| C．Americans always show their true feelings |
| D．Americans usually argue with them |
Why is the extremely competitive nature considered as one of American faults?
| A．Because people from other cultures fear competition. |
| B．Because only American people own it. |
| C．Because it will make people forget leisure. |
| D．Because it may sometimes urge people to do something bad. |
It can be inferred from the passage that . .
| A．American people are more critical of everything than people from other cultures |
| B．the author believes that American character has more faults than virtues |
| C．the author admires American virtues as they are viewed as competitive and anti traditional |
| D．it is difficult for newcomers to get on with Americans |
The passage mainly talks about . .
| A．American virtues | B．American characters | C．American faults | D．American lifestyles |
Almost 55,000 people who have had a major impact on British society are profiled in a new 60-volume book that has taken 12 years to compile.
It has cost more than ￡25million and taken 10,000 writers to update the Oxford Dictionary of National Biography.
Murder victims Stephen Lawrence and James Bulger are among those joining the likes of Queen Victoria and Gandhi.
The new version of the dictionary, which was founded in 1882, costs ￡7,500 and takes up 12 feet of shelf space.
Projects director Robert Faber said Stephen Lawrence was included because his death triggered "dramatic developments in British policing and social policy".
Women make up 10% of the entries - double the previous share - and include Queen Elizabeth I, Dusty Springfield, Linda McCartney and Virginia Woolf, whose father compiled the first edition.
Alongside the famous names are lesser known individuals such as the inventor of snooker, army reservist(预备役军人)Neville Chamberlain.
Stephen Lawrence and James Bulger were both included because of the "overwhelming soul-searching(真挚的自我反省、深思)and examination of education and social policy" which followed their deaths.
Mr Faber said: "These are not just people who were killed but people who had an impact. Jill Dando is there as much for her career but also because her death became a public event.
"So many of these people have seized the public imagination and have contributed to public debate." How much does a volume of the new version cost on average?
| A．More than ￡25million. | B．More than ￡400, 000. |
| C．￡7, 500. | D．￡125. |
How many women are profiled in the New Oxford Dictionary of National Biography?
| A．About 5. | B．About 55. | C．About 550. | D．About 5500. |
It can be inferred that Jill Dando _____.
| A．died in a case of murder which drew the public much attention |
| B．isn’t included in the Oxford Dictionary of National Biography |
| C．is the director of the Oxford Dictionary of National Biography |
| D．is included in the Oxford Dictionary of National Biography only for her death |
_____ are collected in the Oxford Dictionary of National Biography.
| A．Those who were murdered in history | B．Those who have shaped Britain |
| C．Those who are famous all over the world | D．Those who live in Britain |
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!When the star begins to die ______.

Perhaps the most astonishing theory to come out of kinetics, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed．In other words, we learn our looks; we are not born with them.
A baby has generally unformed facial features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around family and friends. This helps explain why the people of some regions of the United States look so much alike. New Englanders or Southerners have certain common facial characteristics that cannot be explained by genetics (遗传学) “The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after permanent (永久的) teeth are set. For many, this can be well into adolescence (青春期). A husband and wife together for a long time often come to look somewhat alike. We learn our looks from those around us. This is perhaps why in a single country there are areas where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many Southerners find cities such as New York cold and unfriendly, Partly because people on Madison Avenue smile less than people on Peach Tree Street in Atlanta, Georgia．People in densely (稠密地) populated urban areas also tend to smile and greet each other in public less than people in rural areas and small towns. Ray Birdwhistell believes that physical appearance ______.
| A．has little to do with culture | B．can be influenced by culture |
| C．is decided by culture | D．varies from place to place |
Ray Birdwhistell can tell what region of the United States a person is from by ______.
| A．how much he or she laughs | B．how he or she raises his or her eyebrows |
| C．what he or she likes best | D．the way he or she talks |
People who live _____ are more friendly according to the passage.
| A．in densely populated areas | B．in the country |
| C．in New York City | D．in the North |
This passage might have been taken out of a book dealing with ______.
| A．physics | B．health | C．chemistry | D．none of the above |
