单选题Avalanche and Its Safety An avalanche(崩) is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are 1 the biggest dangers in the mountains for both life and property. All avalanches are caused by an over-burden of material, typically snowpack(积场), that is too massive and unstable for the slope 2 supports it. Determining the critical load, the amount of over-burden which is 3 to cause an avalanche, 4 a complex task involving the evaluation of a number of factors. Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low 5 of avalanche. Snow does not 6 significantly on steep slopes; also, snow does not 7 easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snow"s angle of rest is 8 35 and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb is: A slope that is 9 enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally, avalanche risk increases with 10 ; that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur. Due to the complexity of the subject, winter travelling in the backcountry is never 100% safe. Good avalanche safety is a continuous 11 , including route selection and examination of the snowpack, weather 12 , and human factors. Several well-known good habits can also 13 the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid 14 to. Never follow in the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are 15 or damaged. Avoid travelling below others who might trigger an avalanche.

Alderman (市议员) Sam Shropshire has introduced a well-meaning (55) to ban retailers from distributing plastic shopping bags in Maryland's capital. instead, retailers would be required to (56) bags made of recycled paper and to sell reusable bags. The city of Baltimore is (57) a similar measure. Opponents of the (58) , however, argue that paper bags are harmful, too: They cost more to make, they (59) more resources to transport, and recycling them causes more pollution than recycling plastic. The argument for depriving Annapolis residents (60) their plastic bags is far from accepted.

单选题Underground Coal Fires -- a Looming Catastrophe Coal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned. These large-scale underground blazes cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can even ignite forest fires, a panel of scientists told the annual meeting of the American Association for the Advancement of Science in Denver. The resulting release of poisonous elements like arsenic and mercury can also pollute local water sources and soils, they warned. "Coal fires are a global catastrophe," said Associate Professor Glenn Stracher of East Georgia College in Swainsboro, USA. But surprisingly few people know about them. Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not caused to disappear and under the right combinations of sunlight and oxygen, can trigger spontaneous catching fire and burning. This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. Such fires in China consume up to 200 million tones of coal per year, delegates were told. In comparison, the U.S. economy consumes about one billion tones of coal annually, said Stracher, whose analysis of the likely impact of coal fires has been accepted for publication in the International Journal of Coal Ecology. Once underway, coal fires can bum for decades, even centuries. In the process, they release large volumes of greenhouse gases, poisonous fumes and black particles into the atmosphere. The members of the panel discussed the impact these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to detect. One of the members of the panel, Assistant Professor Paul Van Dijk of the International Institute for Geo-Information Science and Earth Observation in the Netherlands, has been working with the Chinese government to detect and monitor fires in the northern regions of the country. Ultimately, the remote sensing and other techniques should allow scientists to estimate how much carbon dioxide these fires are emitting. One suggested method of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a heat-resistant grout (a thin mortar used to fill cracks and crevices), which is designed to be pumped into the coal fire to cut off the oxygen supply.

单选题What About Smoking Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn"t know for sure? That the evidence was inconclusive, the science uncertain7 That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves. There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth"s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel"s report: "Science never has all the answers. But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions." Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it"s OK to keep pouring fumes into the air until we know for sure. This is a dangerous game : by the time 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now. Fortunately, the White House is starting to pay attention. But it"s obvious that a majority of the president"s advisers still don"t take global warming seriously. Instead of a plan of action, they continue to press for more research—a classic case of "paralysis by analysis." To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research. But research alone is inadequate. If the Administration won"t take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry, is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

单选题{{B}}第二篇{{/B}} Thanksgiving Day The American Thanksgiving Day celebration goes back to 1621. In that year, a special dinner was prepared in Plymouth, Massachusetts. The people who had settled there had left England because they were forbidden to keep their religious belief. They came to the new land and faced difficulties in sailing across the ocean. The ship which carried them was called "the Mayflower". The North Atlantic was hard to travel. There were bad storms and huge waves. With the help of the Indians, they learned to live in the new land. These Puritans, as they were called, had much to be thankful for. They could enjoy religious freedom. They learned how to grow their crops in accordance with the climate and soil. Now when they selected the fourth Thursday of November for their Thanksgiving celebration, they invited their neighbors, the Indians, to join them in dinner. They also wanted to pray God for the new life. They recalled the group of 102 men, women and children who left England. They remembered those who did not liv tosee the shores of Massachusetts. They thought of the 65 day's journey which tested their strength.
