Passage One Questions 21 to 25 are based on the following passage. Antarctica has actually become a kind of space station—a unique observation post for detecting important changes in the world’s environment.S1 Remote from major sources of pollution and the complex geological and ecological systems that prevail elsewhere, Antarctica makes possible scientific measurements that are often sharper and easier to interpret than those made in other parts of the world. Growing numbers of scientists therefore see Antarctica as a distant early warning sensor, where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from the United States, Switzerland, and France are pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet—a concern they believe the world at large should share. The Transantarctic Mountain, some of them more than 14,000 feet high, divide the continent into two very different regions. The part of the continent to the “east” of the mountains is a high plateau covered by an ice sheet nearly two miles thick. “West” of the mountain, the half of the continent south of the Americas is also covered by an ice sheet, but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disappeared, the western part of the continent would be reduced to a sparse cluster of island. While ice and snow are obviously central to many environmental experiments, others focus on the mysterious“dry valley”of Antarctica, valleys that contain little ice or snow even in the depths of winter. Slashed through the mountains of southern Victoria land, these valleys once held enormous glaciers that descend 9,000 feet from the polar plateau to the Ross Sea.Now the glaciers are gone
perhaps a casualty of the global warming trend during the 10,000 years since the ice age. Even the snow that falls in the dry valleys is blasted out by vicious winds that roar down from the polar plateau to the sea. Left bare are spectacular gorges, rippled fields of sand dunes, clusters of boulders(blG)sculptured fantastic shapes by 100 mile an hour winds and an aura of extraterrestrial desolation Despite the unearthly aspect of the dry valleys some scientists believe that they may carry a message of hope for the verdant(草木繁茂的) parts of the scientists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them 21. Antarctica is scientifically important in that A)it is a space station B)it is an ideal place for the investigation of glaciology C) there is the mysterious dry valley D)it can help people detect global environmental changes 22. The reason for the disappearance of glaciers in the dry valley is A)that they've desended to the ross sea B) that they' ve been blasted out by vicious winds C) the global warming trend ever since the ice age D) that they've been changed into gorges, sand dunes and boulders 23. When the author calls Antarctica "distant early warning sensor", he actually means that A)such equipment has been set up for scientific purpose B) the research groups there are like such kind of sensors C)potential global changes can be seen on Antarctica first D)Antarctica is remote from other parts of the earth 24. Which of the following statements is true according to the article A) There is a cluster of island west of the Transantartic Mountain B) Scientific research on Antarctica only centers on the ice and snow there. C)Dry valleys may be a place to dispose of our pollutants D)All the countries on earth should be concerned about the health of the West Antarctic Ice sheet 25.

The U.S. birthrate began to decline in the middle 1950’s, resulting in a smaller
ollege age population starting in the middle 1970s.S4 Something else happened in the 1970s: the price of oil increased tremendously, driving up the price of almost everything and making Americans aware that their large automobiles used a lot of gasoline. At the same time, foreign car manufacturers had beg un to produce small fuel efficient cars in large quantities for the export market Suddenly, the large, gas guzzling american cars were no longer attractive to American buyers, who began buying foreign cars by the thousands. The American automobile industry went into a recession. Thousands of automotive workers were laid off, as were thousands of people in industries indirectly connected with the auto industry. People who are laid off tend to keep what money they have for necessities like food and housing. they do not have the extra money needed to send their children to college. Their children cannot pay their own college costs, because during a recession they cannot find jobs. High unemployment means that more state funds must be used for social service-unemployment benefits and to aid dependent children, for example-than during more prosperous time It also means, that the states have fewer funds than usual, because people paying fewer taxes. Institutions of higher education depend on two major of income to keep them functioning: tuition from students and funds from the states. At the present time, there are fewer students than in the past and fewer state funds available for higher education the colleges and universities are in trouble 31. What is the main idea of this passage? A)The rising of oil price drove up the price of everythi B) There were many reasons why higher education was in trouble in the 1970′s C) Birthrate began to decline in the USa in 1950S D) High unemployment caused a lot of social problems 32.

The word rubbish could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would p energy if nothing else. The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city.

Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.

This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well
Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed then it will pass through powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers break up everything that can be broken Finally the rubbish will pass under magnets, which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage The first full scale giant recycling plants are, perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps some big cities will be forced to build their own recycling plants before long 36. The main purpose of the passage is A) to show us a future way of recycling wastes B)to tell the importance of recycling wastes C)to warn people the danger of some wastes D) to introduce a new recycling plant 37. How many stages are there in the recycling process? A)3 B)4 C)5 D)6 38. What is the main reason for big cities to build their own recycling plants? A)To deal with wastes in a better way.
