Most animals have little connection with animals of different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership ( 伙伴关系 ) which does good to both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals ( 珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are ever prevented from lighting so that they cannot live normally, the corals will die.1、Some birds like to sit on a sheep because ( ).A、they can eat its parasitesB、 they depend on the sheep for existenceC、 they enjoy traveling with the sheepD、 they find the position most comfortable2、The underlined word "they" in the last sentence of the first paragraph refers to ( ).A、birds and parasitesB、birds and sheepC、parasites and sheepD、sheep, birds and parasites3、What does the second paragraph mainly discuss?

共用题干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.If operation Migration is successful,whooping cranes will______.A:learn to migrate on their ownB:follow airplanes south every yearC:live in Canada all year roundD:be unable to fly back

问答题Wild Birds Treated as Bird-flu Carriers Avian influenza, also known as bird-flu, is dominating headlines in some parts of the world. The first cases of the deadly HSN1 swain of the virus have been confirmed in Europe and there have been new outbreaks in Asia. Bird-flu is here to stay, according to the World Health Organization, and countries are revising their procedures on how to prevent, or at the very least delay, a human pandemic. In areas where the virus has already been confirmed, like Romania, most efforts focus on trying to keep domestic birds away from wild local birds like swans, and migrating birds like geese. In the wetlands of the Danube delta thousands of hens, ducks and geese have already been slaughtered. Some ornithologists plead that we’d better not demonize the wild birds. Bird flu began among poultry in south-east Asia, almost certainly because of the way people treat domestic birds, cramped together in small cages. They infected the wild birds, which are now bringing the virus to Europe and Africa. Poultry are catching it, and sooner or later, so will humans. It’s coming full circles. So don’t blame the birds. Blame human cruelty. On a lake in Mined, not far from the delta capital Tulcea, two pigmy cormorants,10 domestic ducks, egrets, black-headed gulls, and swans, lots of swans. Sleeping. They shouldn’t be sleeping now. It’s the middle of the day! Perhaps they’re sick. Swans have borne the brunt of the bird-flu outbreak here so far. They were weak anyway, because of the floods which have struck Romania this Spring and Summer. Swans thrive in water not much deeper than one metre. They plunge their long necks under water to feed. With water levels unusually high, the swans have take refuge this year in fish farms, where many shallow, man-made pools offer rich pickings. But other birds, domestic and wild, gather there too-and such concentrations of birds, experts say, create a perfect environment for spreading disease. In the second confirmed bird-flu cluster in the delta,137 swans have died, on a fish farm in the village of Maliue. In the third cluster, near the Ukrainian border,15 swans have died so far. The number may not be huge, but this is undoubtedly the tip of the avian influenza iceberg. Bird-flu is already present in Romania’s neighbors, Ukraine, Moldova, and Bulgaria. White-fronted geese can travel 500 kilometers in a single day! Scientists should concentrate on a vaccine to prevent the virus in birds, and not put all their efforts into the human version. According to experts from the World Health Organization, the virus will remain for a long time in the region. More cases of bird-flu will be discovered, And each time, a major quarantine operation will have to be launched. To kill poultry, to closely observe those who have come into contact with sick birds, and seal off the area. People throughout this wetland region will just have to learn a new way of life. And so will their hens and ducks and geese. Like the tale of the Sultan’s gold coin, no one can say how this story will end.
