Unusual incidents are being reported across the Arctic. Inuit (因纽特人) families going off on snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea of mud. There are also reports of sea ice breaking up earlier than usual, carrying seals beyond the reach of hunters. Climate change may still be a rather abstract idea to most of us, but in the Arctic it is already having great effects-if summertime ice continues to shrink at its present rate, the Arctic Ocean could soon become almost ice-free m summer. The knock-on effects are likely to include more warming, cloudier skies, and higher sea levels. Scientists are increasingly eager to find out what"s going on in the Arctic. For the Inuit the problem is urgent. They live in unsteady balance with one of the toughest environments on earth. Climate change, whatever its causes, is a direct danger to their way of life. Nobody knows the Arctic as well as the locals, which is why they are not content simply to stand back and let outsider experts tell them what"s happening. In Canada, where the Inuit people are trying hard to guard their hard-won autonomy in the country"s newest land, Nunavut, they believe their best hope of survival in this changing environment lies in combining their ancestral knowledge with the best of modern science. This is challenge in itself. The Canadian Arctic is a vast, treeless polar desert that"s covered with snow for most of the year. Adventure into this area and you get some idea of the hardships facing anyone who calls-this home. Farming is out of the question and nature offers few pickings. Humans first settled in the Arctic a mere 4,500 years ago, surviving by taking advantage of sea fish. The environment tested them to the limits: sometimes the settlers were successful, sometimes they failed and disappeared. But around a thousand years ago, one group appeared that was uniquely well adapted to deal with the Arctic environment. These Thule people moved in from Alaska, bringing dogs, iron tools and the like. They are the ancestors of today"s Inuit people. | |

The energy crisis (危机) has made people aware of how the careless use of the earth"s energy has brought the whole world to the edge of disaster. The over-development of motor transport, with its increase of more cars, more traveling, has contributed to the near-destruction of our cities and the pollution not only of local air but also of the earth"s atmosphere. Our present situation is unlike natural disasters of the past. Worldwide energy use has brought us to a state where long-range planning is vital. What we need is not a continuation of our present serious state, which endangers the future of our country, our children, and our earth, but a movement forward in order to work rapidly and effectively on planetary problems. This country has been falling back under the continuing exposures of loss of morality and the revelation (揭 露) that lawbreaking has reached into the highest place in the land. There is a strong demand for morality to turn for the better and for some devotion that is vast enough and yet personal enough to enlist the devotion of all. In the past it has been only in a way in defense of their own country and their own benefits that people have been able to devote themselves wholeheartedly. This is the first time that we have been asked to defend ourselves and what we hold dear in cooperation with all the other people of this planet, who share with us the same endangered air and the same endangered oceans. There is a common need to reassess our present course, to change that course and to employ new methods through which the world can survive. This is a priceless opportunity. To grasp it, we need a widespread understanding of nature if the crisis we and the world are facing is no passing inconvenience, no byproduct of the ambitions of the oil-producing countries, no environmentalists" only fears, no byproduct of any present system of government. What we face is the result of the invention of the last four hundred years. What we need is a transformed life style. This new life style can flow directly from science and technology, but its acceptance depends on a sincere devotion to finding a higher quality of life for the world"s children and future generation. | |
1. Which of the following has nearly destroyed our cities? | |
[ ] | |
A. The loss of beliefs and ideas. B. More of law-breaking. C. Natural di8asters in many areas. D. The rapid growth of motors. | |
2. By comparing past problems with present ones, the author draws our attention to the _____. | |
[ ] | |
A seriousness of this crisis B. ineffectiveness of laws C. similarity of the past to the present D. hopelessness of the situation | |
3. Which of the following is used as an example to show the loss of morality? | |
[ ] | |
A. Disregard for law. B. Lack of devotion. C. Lack of understanding. D. Destruction of cities. | |
4. The author wrote the passage in order to _____. | |
[ ] | |
A. make a recommendation for a transformed life style B. limit ambitions of the people of the whole world C. demand devotion to nature and future generation D. encourage awareness of the decline of morality | |

The hole in the Earth"s ozone layer (臭氧层) has until now protected Antarctic from the worst effects of global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3℃ on average, with melting ice contributing to a global sea level increase of up to 1.4 metres. In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% mcrease in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctic, making much of the continent surface colder than usual. But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an mcrease in average air temperatures of around 30℃ and a reduction in sea ice by around a third. The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctic ice sheets, said, "The ice sheets in Antarctic are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly." Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctic has already resulted in a 10% rise in global sea level in recent decades. Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected-Antarctic may be a long way away but it is an important part of the Earth"s system," said Johnson. "It contains 90%of the world"s ice, 70% of the world"s fresh water and that is enough, if it melts completely, to raise sea levels by 63 metres." Even in aworse-case situation scientists don"t expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around l.4 metres higher by the end of the century. | |

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life. Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. "We"ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we"ve been able to record this increasing quantity of atmospheric CO2 into the ocean." Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular. "As carbon dioxide dissolves (溶解) in the water or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic." The seawater Dore and his colleagues have analyzed confirms what the theory predicts. The effect was particularly striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation. "It"s important to realize that the oceans are really becoming acidic. And it could have negative impacts on a whole variety of sea life from fish to coral. It"s potentially catastrophic." | |
