举一反三
Many animal and plant species have become extinct（灭绝的）and many more are in critical danger. Finding ways to protect the earth"s wildlife and conserve（保护）the natural world they inhabit（居住）is now more important than ever.
Dodo
The Dodo is a classic example of how human caused damage to the earth"s biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island"s trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681.
Rhinos
The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves（保护区）. Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers（偷猎者）.
The Giant Panda
The future of the World Wildlife Fund"s symbol is far from certain. As few as 1000 remain in the wild． The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, The panda"s distinct black and white patched coat fetches a high price on the black market and determined poachers still pose（造成）one of the most serious threats to the animals continued existence.
Whales
The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world"s oceans have been declared whale sanctuaries（保护区）, 7 out of 13 whale species remain endangered． Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions（碰撞）with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.
Tigers
The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.
小题1:It implies that _______.
| A．The Dodo lacked the ability to protect itself from other animals |
| B．Sailors to the Island of Mauritius lived mainly on the Dodo |
| C．The Dodo used to be a strong animal that liked fighting. |
| D．The Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius |
| A．The Dodo, Rhino and Giant Panda． |
| B．The Rhino, Whale and South China Tiger. |
| C．The Rhino, Panda, Whale and Tiger. |
| D．The Dodo and the Bali, Javan, and Caspian tigers. |
| A．The whale’s rich oil |
| B．The panda"s black and white patched coat |
| C．The Rhino horn and tigers’ bones and organs |
| D．The Dodo’s delicious meat |
| A．The number of South China tigers has reached crisis point. |
| B．Many animals are threatened with extinction as a result of human activity. |
| C．People hunt for the endangered animals for high profit. |
| D．The Whale is the representing mark for the World Wildlife Fund． |
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like a science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don’t age. They have now moved on to the small, non-hibernating mammals (哺乳动物) like rats.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex (复杂的). "It’s like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia．Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陈代谢) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system. There is a challenge of designing a suitable protective shelter (栖身所). Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission (使命) to Jupiter’s moon (木星的卫星) Callisto could be an opportunity to use human hibernation. The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045.
小题1:According to the article, the hibernation research ______.
| A．is just an idea | B．is always a science fiction |
| C．has already finished successfully | D．has made some progress |
| A．less sleep | B．more food | C．less energy | D．more movement |
Exploration Mission to Jupiter’s moon Callisto.
| A．will be | B．has been planned for |
| C．is certain to be | D．may be |
| A．Hibernation Study For Space Travel | B．Welcome To Our Space Travel |
| C．To Hibernate, To Live Longer | D．Welcome To The Milky Way |
A NASA satellite called QuikSCAT has discovered highways of wind over the Earth"s oceans. Scientists believe these invisible roads may explain why many nonflowering plants, such as mosses (苔) and lichens (地衣), grow where they do.
The satellite is able to send microwaves (微波) from space to the surface of the ocean. The pattern of signals that come back shows which way the winds are blowing.
Using this data, the scientists studied a group of islands in the southern hemisphere (半球), near Antarctica．Winds tend to blow anticlockwise (逆时针) in this region, but there are lots of local differences.
When the researchers compared these local patterns to botanical (植物学) data, they found that the wind had an important effect on where species of mosses, lichens, and other nonflowering plants grow.
For example, Bouvet Island and Heard Island, share 30 per cent of their moss species, 29 per cent of liverworts (叶苔), and 32 per cent of lichens — even though they are 4,430 kilometers apart. In contrast, Gough Island and Bouvet Island, separated by just 1,860 kilometers of sea, share only 16 per cent of mosses and 17 per cent of liverworts. They have no lichens in common.
Ferns (蕨类植物) and flowering plants don"t travel as well in the wind, so they don"t show the same kinds of distribution (分布) patterns.
小题1:This story is about _____.
| A．the discovery of wind highways | B．how wind travels |
| C．how wind affects different plants | D．one function of the wind |
| A．signal | B．pattern | C．information | D．research |
| A．Bouvet Island, Heard Island and Gough Island are all in the southern hemisphere. |
| B．Winds in the researched area blow anti-clockwise. |
| C．The scientists shouldn"t base this research on how winds affect where ferns grow. |
| D．Without the discovery of QuikSCAT, the research wouldn"t have made sense. |
Since the earth"s creation millions of years ago, the ecosystem has worked as an interdependent system relatively undisturbed by outside forces. But recently, especially since the Industrial Revolution, human beings have begun to disturb the balance of nature. Natural resources have been severely depleted (消耗) (forests have been destroyed, fertile land worn away, water polluted, and minerals used up), and the life-support system of air, water, and land has been poisoned by a variety of waste products and chemicals.
The degree of these problems was noted in a report by the U.N. Developing Council on Environmental Quality. This report predicted that if present trends continue, the world will be more crowded and polluted and less stable ecologically and politically than the world we live in now.
The twin problems of resource shortages and pollution are caused by three social forces. First, the tremendous increase in population growth constantly increases the demand for food, energy, and other products. As the current population continues to increase, the stress on an already overburdened environment will be increased．A second source of the problem is the concentration of people in urban areas, where the ecosystem simply cannot absorb their waste products. Finally, environmental problems are worsened as more and more nations move toward modem development: an increased reliance on modern technology. As these nations become more technological, they will consume more energy, deplete more natural resources, and create more waste products than the biosphere can absorb.
小题1:The life-support system is composed of _____.
| A．air, water and land | B．the earth, the sun and energy |
| C．food, land and energy | D．food, energy and the sun |
| A．change energy from the sun into food for humans |
| B．depends on the sun for enough supplies of air, water and land |
| C．exists in the surface layer of the earth and the surrounding atmosphere |
| D．is a complex but independent system |
| A．natural forces | B．human activities | C．social movements | D．political changes |
| A．the effects of Industrial Revolution on human beings |
| B．the importance of life-support system to human beings |
| C．the significance of balance of nature |
| D．the destruction of life-support system and its causes |
The team has just finished a second year of work on the 1,020-mile highway. "The road is the greatest single footprint of activity we"ve seen in the Antarctic (南极洲)," said Alan Hemmings, an Australian environmentalist.
The highway will provide a new way for supplies to be trekked (拉, 搬) across the earth on tractor-pulled sleds (雪橇). This method will use a lot less fuel than an aircraft, the current (当前的) way that scientists and supplies reach the Amundsen-Scott Base, a U.S. research station in the South Pole. The highway will also allow for equipment that is too big for planes to carry to be brought to Antarctica．Even with these benefits, there is one disadvantage—a round trip on the road will be 30 days, compared to a few hours by plane.
Making this 20-foot-wide road isn"t easy, and it takes a lot of time. The crew (工作队) has been working on the road for two summers, when it"s warmer and easier to work with the ice. It probably won"t be completed until 2006.
Crevasses (裂缝), or cracks, in the land often make the construction difficult. Crevasses are kind of like pot holes that form when surface ice is stretched．This can be very dangerous, especially when the crevasses are hidden under a layer (层) of snow and can"t be seen.
"Last year it took us three months to go three miles across a crevasse field, full of dangerous, hidden crevasses," said the project"s manager, John Wright. Each year, more crevasses appear and they have to be filled with snow and ice so the road is safe for travel. The road will also be lined with green flags so travelers know where the safe surface is.
小题1: It will probably take ______ years to complete the ice highway.
| A．2 | B．4 | C．6 | D．8 |
| A．giving supplies to the research station in the South Pole |
| B．taking scientists to the South Pole |
| C．taking travelers to a tour of Antarctic |
| D．bringing huge equipment to Antarctic |
Pole?
| A．30. | B．34. | C．68. | D．88. |
| A．Other crevasses won’t appear if a crevasse has been filled. |
| B．Many new crevasses will form after a crevasse has been filled. |
| C．Travelers can drive their sleds on the ice highway freely. |
| D．There will be less danger if the crevasses are covered by snow. |
