BThree years ago, five parrots were set free in a wild place of Arizona, thousands of miles from the Channel Islands in Jersey where they had been looked after by zookeepers. No evolutionary strategies informed them how to behave in this new landscape of mountainous pine forest unoccupied by their kind for 50 years. To the researchers’ surprise, they failed to make contact with a group of wild parrots imported from Mexico and set free at the same time. Within 24 hours the reintroducing ended in failure, and the poor birds were back in cages, on their way to the safety of the Arizona reintroduction programme.Ever since then, the programme has enjoyed great success, mainly because the birds now being set free are Mexican birds illegally caught in the wild, confiscated (没收) on arrival north of the border, and raised by their parents in the safety of the programme. The experience shows how little we know about the behaviour and psychology(心理) of parrots, as Peter Bennett, a bird researcher, points out: “Reintroducing species of high intelligence like parrots is a lot more difficult. People like parrots, always treating them as nothing more than pets or valuable ‘collectables’.”Now that many species of parrot are in immediate danger of dying out, biologists are working together to study the natural history and the behaviour of this family of birds. Last year was an important turning point: conservationists founded the World Parrot Trust, based at Hayle in Cornwall, to support research into both wild and caged birds.Research on parrots is vital for two reasons. First, as the Arizona programme showed, when reintroducing parrots to the wild, we need to be aware of what the birds must know if they are to survive in their natural home. We also need to learn more about the needs of parrots kept as pets, particularly as the Trust’s campaign does not attempt to discourage the practice, but rather urges people who buy parrots as pets to choose birds raised by humans.55. What do we know about the area where the five parrots were reintroduced?A. Its landscape is new to parrots pf their kind.B. It used to be home to parrots of their kind.C. It is close to where they had been kept.D. Pine trees were planted to attract birds.

IV. Reading Comprehension (60 points)Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.Passage OneWild and farm birds often get a flu virus. Yet they usually are able to carry the virus without getting sick.In 1997 six people in Hong Kong died of a different kind of bird flu virus. It is called the h-five-n-one virus. The Hong Kong government quickly ordered the killing of all farm birds there. That stopped the spread of h-five-n-one to people in Hong Kong.Yet the virus bad already spread to other parts of Asia. It was found in 16 countries between 2003 and 2006.The h-five-n-one virus first appeared in Africa. This raised many concerns about the spread of the disease. Scientists do not know exactly how bird flu came to Africa. At first, they thought wild birds were to blame. Now, officials with the U. N. Food and Agriculture Organization believe the main cause is trade in farm birds.The bird flu virus is found in the waste and liquids of infected birds. The virus spreads when healthy birds or people touch sick birds or nay infected (被感染了的) part of sick birds. Right now, the virus is not spreading among person to person. But the virus could change and start spreading among people. Health officials believe that it is even more possible now that bird flu has spread in Africa, and that is why international organizations are working so hard to stop its spread.The best way to stop the spread of bird flu is to kill all the chickens in an area where bird flu has been discovered. More than 145 000 chickens have been killed in Nigeria since bird fin was first found one year ago.36. The passage focuses on ______.A. wild and farm birdsB. a fin virusC. bird fluD. infected birds

Why Buy Shade-Grown Coffee?When people argue about whether coffee is good for health,they're usually thinking of the health of the coffee drinker. Is it good for your heart?Does it increase blood pressure?Does it help you concentrate?However,coffee affects the health of the human population in other ways, too.Traditionally,coffee bushes were planted under the canopy（树冠）of taller indigenous（土生土长的）trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.At first,this increases production because more coffee bushes can be plan- ted if there aren't any trees.With increased production come increased profits.Unfortunately,deforesting for coffee production immediately decreases local wildlife habitat Native birds nest and hide from predators（捕食者）in the tall trees and migrating birds rest there.Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesti- cides kill insects that eat coffee plant,but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well,and can even enter the water that people will eventually drink.Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade.We can support these farmers by buying coffee with such labels as“shade grown” and“bird friendly.”Sure,these varieties might cost a little more.But we're paying for the health of the birds,the land,ourselves,and the planet. I think it's worth it. What does increased production of full-sun coffee bring about?A: More insects.B:Better quality coffee.C:Larger farms.D:Higher profits.

Operation MigrationIf you look up at the sky in the early fall in the northern part of North America,you may see groups of birds.These birds are flying south to places where they can find food and warmth for the winter.They are migrating（迁徙）.The young birds usually learn to migrate from their parents.They follow their parents south.In one unusual case,however,the young birds are following something very different.These birds are young whooping cranes,and they are following an airplane!The whooping crane is the largest bird that is native to North America.These birds al-most disappeared in the 1800s.By 1941,there were only about 20 cranes alive.In the 1970s, people were worried that these creatures were in danger of disappearing completely.As a result,the United States indentified whooping cranes as an endangered species that they needed to protect.Some researchers tried to help.They began to breed whooping cranes in special parks to increase the number of birds.This plan was successful.There were a lot of new baby birds.As the birds became older,the researchers wanted to return them to nature.However,there was a problem:These young birds did not know how to migrate.They needed human help.In 2001,some people had a creative idea.They formed an organization called Operation Migration.This group decided to use very light airplanes,instead of birds,to lead the young whooping cranes on their first trip south.They painted each airplane to look like a whooping crane.Even the pilots wore special clothing to make them look like cranes.The cranes began to trust the airplanes,and the plan worked.Today,planes still lead birds across approximately 1,200 miles(1,931 kilometers), from the United States-Canadian border to the Gulf of Mexico.They leave the birds at differ-ent sites.If a trip is successful,the birds can travel on their own in the future.Then,when these birds become parents,they will teach their young to migrate.The people of Operation Migration think this is the only way to maintain the whooping crane population.Operation Migration works with several other organizations and government institutes.Together,they assist hundreds of cranes each year.However,some experts predict that soon,this won't be necessary.Thanks to Operation Migration and its partners,the crane population will continue to migrate.Hopefully,they won't need human help any more.The distance covered by the young whooping cranes on their trip south is______.A:120 milesB:1,931 milesC:1,200 milesD:2,000 miles

问答题Practice 7 When people argue about whether coffee is good for health, they're usually thinking of the health of the coffee drinker. Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too. Traditionally, coffee bushes were planted under the canopy (树冠) of taller indigenous (土生土长的) trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits. Unfortunately, deforesting for coffee production immediately decreases local-wildlife habitat. Native birds nest and hide from predators (捕食者) in the tall trees and migrating birds rest there. Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink. Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade grown" and "bird friendly." Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it's worth it.

单选题Prolonged and unseasonable frosts produce frost rings in deciduous trees, which grow in moderate climates. Frost rings do not appear in any of the fossilized deciduous trees that have been found in Antarctica. Hence, it is unlikely that such frosts occurred in Antarctica at the time the fossilized trees lived. Which of the following is an assumption on which the argument depends?A
There are fossilized nondeciduous trees from Antarctica that bear frost rings.B
Deciduous trees are more likely to bear frost rings than are other tree varieties.C
The process of fossilization does not completely obscure frost rings in deciduous trees.D
Present-day deciduous trees are more sensitive to changes in temperature than were the deciduous trees of ancient Antarctica.E
Prolonged and unseasonable frosts that might have occurred in Antarctica when the now-fossilized trees were still living did not always produce frost rings in deciduous trees.
