People at work ___43___ (routine) think of creative ways to solve problems. Maybe you have a ___44___ (trick) question to answer! Here are three techniques for you. This technique involves taking ___45___ (relate) ideas and finding links between them. First, think about the problem. Then find an image, for example, a candle. Write down all the ideas ___46___ (associate) with candles. The next stage is to relate the ideas to the problem. So imagine you want to buy a friend an___47___ (origin) present; you could buy him tickets to a match or take him out for the night. Imagine that normal limitations don't exist. Think about the new___48 ___ (possible). If your goal is to learn to ski, you can now practice ___49___ (ski) every day of your life. Now adapt this to reality.

Soot（烟灰）and Snow: a Hot Combination①New research from NASA scientists suggests emissions（释放）of black soot alter the way sunlight reflects off snow. According to a computer simulation（模拟），black soot may be responsible for 25 percent of observed global warming over the past century.②Soot in the higher latitudes（纬度）of the Earth，where ice is more common，absorbs more of the sun's energy and warmth than an icy，white background. Dark-colored black carbon，or soot，absorbs sunlight，while lighter colored ice reflects sunlight.③Soot in areas with snow and ice may play an important role in climate change. Also，if snow and ice covered areas begin melting，the warming effect increases，as the soot becomes more concentrated on the snow surface. “This provides a positive feedback，as glaciers and ice sheet smelt，they tend to get even dirtier，" said Dr. James Hansen，a researcher at NASA's Goddard Institute for Space Studies，New York.④Hansen found soot’s effect on snow albedo（反照率）（solar energy reflected back to space），which may be contributing to trends toward early springs in the Northern Hemisphere，such as thinning Arctic sea ice，melting glaciers and permafrost（永冻层）.Soot also is believed to play a role in changes in the atmosphere above the oceans and land.⑤”Black carbon reduces the amount of energy reflected by snow back into space，thus heating the snow surface more than if there were no black carbon，"Hansen said. Soot’s increased absorption of solar energy is especially effective in warming the world's climate. “This forcing is unusually effective，causing twice as much global warming as a carbon-dioxide（二氧化物）forcing of the same magnitude（量，大小），”Hansen noted.⑥Hansen cautioned , although the role of soot in altering global climate is substantial , it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century. Such gases are expected to be the largest climate forcing for the rest of this century.⑦The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes. These observations were consistent with the researchers ' climate model simulations, which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight.【第16题】Paragraph①____.A.Soot' s Role in Climate Changes Above Oceans and Land;B.Observations of Warming in the Northern Hemisphere;C.Explanation of Increased Warming Effect Caused by Soot;D.Black Soot in Snow and Icy Areas Leading to Climate Change;E.Black Soot Contributing to Global W arming;F.Greenhouse Gases as the Main Factor of Global Warming
