考题 Many people believe the glare from snow causes snow blindness.Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of "snow light". The United States Army has now determined that the glare from snow does not cause snow-blindness in troops in a snow-covered country.Rather, a mans eyes frequently find nothing to focus on in a broad expanse of a snow-covered area.So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at.Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscle aches.Nature balances this annoyance by producing more and more liquid which covers the eyeballs.The liquid covers the eyeballs in increasing quantity until vision blurs.And the result is total,even though temporary,snowblindness. Experiments led the Army to a simple method of overcoming this problem.Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape.Even the scouts themselves throw lightweight, dark-colored objects ahead on which they too can focus. The men following can then see something.Their gaze is arrested.Their eyes focus on a bush and having found something to see, stop searching through the snow- blanketed landscape.By focusing their attention on one object at a time, the man can cross the snow withoutbecoming hopelessly snowblind or lost.In this way the problem of crossing a solid white area is overcome.The eyeballs become sore and the eye muscles ache because______.A.tears cover the eyeballsB.the eyes are annoyed by blinding sunlightC.the eyes are annoyed by blinding snowD.there is nothing to focus on

考题 [A] snow [B] earth [C] room [D] ice

The United States Army has now determined that glare from snow does not cause snow- blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing,hour after hour, the eyes never stop searching and the eyeballs become sore and the eye musclesache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs, then is observed, and the result is total, even though temporary, snow-blindness.

考题 共用题干 New research from NASA scientists suggests emissions of black soot after the way sunlight re- flects off snow.According to a computer simulation,black soot may be responsible for 25 percent of observed global warming over the past century. Soot in the higher latitudes(维度)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.Soot 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 increase,as the soot becomes more con-centrated on the snow surface.“This provides a positive feedback,as glaciers and ice sheets melt, they tend to get even dirtier.”said Dr. James Hansen,a researcher at NASA's Goddard Institute for Space Studies,New York.Hansen found soot's effect on snow albedo(反照率),which may be contributing to trends to-ward early springs in the Northern Hemisphere,such as thinning Arctic sea ice and melting glac-iers permafrost. Soot also is believed to play a role in changes in the atmosphere above the oceans and land.“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 absorp-tion of solar energy is especially effective in warming the world's climate.“ This forcing is unusual-ly effective,causing twice as much global warming as a carbon-dioxide forcing of the same magni-tude.”Hansen noted.Hansen 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 the century.The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes. These observations were coherent with the researchers' climate model situations,which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight. What is the main cause of climate warming during the past century?A: Soot.B: Snow.C: Greenhouse gases.D:.Wind.

考题 单选题Passage1 Questions 1 to 5 are based on the following passage. It's interesting that the arrival of snow has the effect on people in different countries.(76) For some countries it is an important happening to celebrate each year, while for others a catastrophe (灾害) or even a wonder. But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year.Britain is one of them, for which the arrival of snow quite simply creates problems.Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way.Normal communications are affected as well: telephone calls become difficult and the post immediately takes more time than usual.And almost within hours there are also certain shortages-bread, vegetables and other things-not because all these things can no longer be produced or sent to shops,but mainly because people are frightened and go out and store up with food and so on...just for fear that something bad should happen. But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don't have such problems.It is simply because there is not enough planning and preparation.We need money to buy equipment to deal with snow and ice.To keep the roads clear, for example,requires snow-ploughs (扫雪机) and machines to spread salt.(77) The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on.3 After a few hours' snowing there are often some shortages of food because______.A shops have closed downB people buy as much as they canC farmers can produce no moreD people eat more vegetables
