单选题Home Fibre Plans Survive Downturn The latest figures on superfast broadband delivered by fibre to the home(FTTH) shows 18% growth over the last survey compiled in late 2008. The continued growth suggests that the global economic downturn has not hit plans to build a fibre infrastructure. Sweden tops the list of nations rolling out the technology, with 10.9% of its broadband customers using fibre. Karel Helsen, president of Europe's Fibre-To-The-Home Council, said the growth matched predictions that were revised when the credit crunch started to make itself felt. By 2012, the FISH Council expects that 13 million people across 35 European nations will have their broadband delivered by fibre. Such services would start at speeds of 100 megabits per second(mbps), said Mr. Helsen. Around Europe more than 233 projects were underway to lay the fibre that would connect homes or buildings to the net, said Mr. Helsen. Many of those, he said, were being operated by local governments or smaller net firms. They were interested in FTTH because of the economic and social benefits it brought, said Mr. Helsen. The low delay in data transfer in high-speed fibre networks made possible novel uses of broadband, he said. "No delay is very important," he said," specifically if you talk about applications that are time dependent such as personal communications, conference calls or video calls where delays cause a lot of interference. "While early FTTH services were concentrated in cities, said Mr. Helsen, many more were reaching out to rural areas for e—health and e—learning projects. Separate studies show that all FTTH infrastructure carl have a direct impact on local economic output, said Mr. Helsen. The UK, France and Germany have yet to break into the list of top ten FTTH nations.

单选题Money and Love Paul had long promised to marry Clara. But at thirty-three he met and married Alice. Clara was driven mad. Paul was taken to court. The judge ordered him to pay Clara $600 because of the broken promise. Paul had to borrow the money from a moneylender. He agreed to pay back $5 a month—for twenty years. His wages at the time were $16 a month. Paul and Alice were poor but not unhappy. They had little enough food, certainly, even before the children began to arrive. Each month Paul paid $5 to the moneylender. He worked hard, never taking a holiday. In time, there were seven mouths to feed. Illness was always with them. It grew serious when the oldest child was eight. The years of hunger weakened the family, because each month Paul paid $5. The details of the sickness were ugly, but the result was this: After twelve years of family life, Paul was alone in the world. He lived alone, except for memories. Work was not now a god for him. it was a pain-killer. Each month he paid, and in time the twenty years ended. From that moment his wages were his own. One day, it was a holiday—he went to the seaside. He sat down on a seat by the sea. A middle-aged woman came and sat down near him. They recognized each other at once. The woman said, "The $600 has been in the bank since the day it was paid to me. It is now $6,000, and I have kept it for you. Will you let me share it with you?" "No," said Paul, gently. "Each thousand is a lost life in a desert between us. It can never bring any happiness."

单选题Avalanche (雪崩) and Its Safety An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are (51) the biggest dangers in the mountains for both life and property. All avalanches are caused by an overburden of material, typically snowpack (积雪场), that is too massive and unstable for the slope (52) supports it. Determining the critical load, the amount of over-burden which is (53) to cause an avalanche, (54) 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 (55) of avalanche. Snow does not (56) significantly on steep slopes; also, snow does not (57) easily on fiat slopes. Human-triggered (激发) avalanches have the greatest incidence (发生率) when the snow's angle of rest is (58) 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 (经验法则) is: A slope that is (59) 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 (60) ; 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 (人烟稀少的地区) is never 100% safe. Good avalanche safety is a continuous (61) , including route selection and examination to the snowpack, weather (62) , and human factors. Several well-known good habits can also (63) the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid (64) 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 (65) or damaged. Avoid traveling below others who might trigger an avalanche.
