Not many years ago, some American farmers began to complain about hawks(鹰). The hawks were killing chickens. The farmers did not know what to do. They went to the government officials and asked for help.
The officials said, “ We’ll pay you for each hawk you kill.” The farmers began to kill the hawks. Many hawks were killed, but the farmers now had another problem. The field mice were growing in number and they were eating up the farmers’ corn. Hawks eat not only chickens but also field mice. They eat more field mice than chickens. But if the farmers had known that, they would not have upset(打乱) the balance of nature. In one part of the USA, there are deer which eat a kind of wild rose. The deer are eaten by mountain lions. The number of deer, mountain lions, and wild rose does not change much if people stay away from them. If there are too many deer, mountain lions will increase rapidly in number and kill many deer. If there are too many mountain lions, there will be fewer deer and there will be more roses.
It is always necessary for us to keep the balance of nature. The government once killed almost all the mountain lions to protect the deer. Soon there were so many deer that they ate up all the wild roses. Then they began to eat the green leaves of young trees which were important to the farmers.
So the farmers protected their trees from the deer. The deer had nothing to eat, and many of them died.
The government learned a valuable lesson from nature.
44. What had happened after the hawks were killed?
A. People wouldn’t worry about their chickens.
B. The number of the field mice became too large.
C. The number of the field mice became small.
D. The field mice were eating up the farmers’ corn.
45. Why did American people have to protect their trees?
A. Because the mountain lions destroyed the trees.
B. Because there were so many deer that they began to eat the green leaves.
C. Because they wanted the trees to grow well.
D. Because the trees are more important than the deer.
46. What can we learn from the article?
A. We must keep the balance of nature.
B. We must not kill any animals.
C. we must feed the hawks with our corn to keep the balance of nature.
D. Both A and B.
June 26, 2000 — the Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遗传的) map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长) human life. But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.
For the last few years, the genetic advances in the developing field of biotechnologyhave provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic codehave opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlockin
g the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses. Why did the scientists work hard at mapping the human genome?
| A．Because the human genome can destroy many illnesses. |
| B．Because the human genome's completion can help them get rid of many diseases. |
| C．Because they wanted to be better known than others. |
| D．Because the human genome can provide a lot of chances of work. |
Which country studied the genes most rapidly in the world?
| A．Japan. | B．Germany. | C．The United States. | D．China. |
Which of the following is NOT true?
| A．If the genes can be found, scientists can study many new ways to cure illnesses. |
| B．The scientists have made great progress in connecting the genes with the cancers. |
| C．Many medical companies show great interest in drawing the human genome map. |
| D．The United States began the Genes Study early in the 19th century. |
Th
e author suggests that the Human Genome Project can cause _______.
| A．the policy makers to feel very worried and careful |
| B．the scientists to work harder |

Breathe, wave and smile.Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.
It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement(graduation ceremony).
Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.
Our principal, Mr Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).
Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”
Then came the core(the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.
To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.
A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage. What’s the article mainly about?
| A．An American high school’s graduation ceremony. |
| B．The opening ceremony of a sports meeting. |
| C．A presentation of college diplomas. |
| D．A US college’s farewell party. |
Which of the following statements about the author is FALSE?
| A．She was one of the graduates. |
| B．She was a foreign exchange student. |
| C．She was excited to receive her diploma. |
| D．She felt it great to be at the ceremony. |
The right order of the following events is______.
a.Diplomas were presented to graduates. b.Students gave farewell speeches.
c.The US national anthem was played. d.The principal gave a short, warm speech.
e.Seniors went into the stadium.
| A．b,c,a,d,e | B．c,d,b,e,a | C．d,b,e,a,c | D．e,d,c,b,a |

The number of speakers of English in Shakespeare’s time is estimated(估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.
In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.
The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, tech
nology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West. What would be the best title for this passage?
| A．The Difficulties of Learning English |
| B．International Communications |
| C．The Standard Varieties of English |
| D．English as a World Language |
Which of the following statements is NOT true?

| D．People learn English for a variety of reasons. |
According to the passage, what is the main reason for the widespread use of English?
| A．It was popular during Shakespeare’s time. |
| B．It is used in former British colonies. |
| C．It serves the needs of its native speakers. |

Trees should only be pruned (修剪) when there is a good and clear reason for doing so and, fortunately, the number of such reasons is small. Pruning involves the cutting away of overgrown and unwanted branches, and the
inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.
Firstly, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseased or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.
One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but it is a wound that will heal. Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce harm to the trees which have been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually done without interference from the leaves and also it is very unlikely that the cuts will bleed. If this does happen, it is, of course, impossible to paint them properly.
