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?

Air pollutionPeople and air pollution are often in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major kind of air pollution is the gas from cars. Statistics(统计资料) show that 93 percent of all auto trips are within cities.Another major kind of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the county.On the average, we throw away more rubbish than the year before. The burning of rubbish makes air pollution even worse. Many major industries are also responsible for the dirty air in the around cities. The fumes(烟)from iron, steel, chemical, and petrol production add particles(微粒)to the air.The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode(腐蚀). In some of the larger cities, these fumes endanger the lives of human beings by contributing to lung diseases and causing early death.26. The key point of the passage is that().A. the cause of air pollution is peopleB. the causes and the effects of air pollution are both found in citiesC. the effects of air pollution range from headaches to death27.

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.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
