Irradiating Food
Irradiating fruits, vegetables, pork and chicken to kill insects and bacteria has been approved by the Food and Drug Administration over the past decade or so. Irradiation of other meats, such as beef and lamb, is being reviewed. Federal approval does not require that industry adopt the process, and few food processors presently offer irradiated products.
Market studies have shown that many consumers are afraid that eating irradiated foods may cause cancer, despite scientific studies that prove the safety of treated foods. Some people argue that more severe government inspection, higher food-safety standards, and more careful-preparation practices by consumers are all that is needed to ensure that food is safe. Consequently, companies currently see no need to spend millions of dollars outfitting processing plants with the equipment necessary for a process that very few shoppers are in favor of.
All supermarkets that sell irradiated food must label the food either directly on the packaging, or, in the case of bulk items like fruits and vegetables, by placing a sign nearby. There is no requirement for the labeling of irradiated food served by chain restaurants or hospitals that buy directly from distributors, nor any regulations for products that contain irradiated ingredients.
Presently, the FDA allows food to be treated with three types of radiation -- gamma rays, high-energy electrons, and X rays -- and sets limits on doses, depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it. Different types of food, because of their molecular compositions, may require different doses of radiation.
1. According to the passage, killing insects and bacteria present in foods by irradiating is not completely approved by the US government.
A. Right B. Wrong C. Not mentioned
2. There are quite a number of food processors which are interested in producing irritated foods.
A. Right B. Wrong C. Not mentioned
3. Some consumers are doubtful of the safety of irradiated foods and suggest a more severe government inspection be taken.
A. Right B. Wrong C. Not mentioned
4. Some companies foresee the promising future of setting up food processing factories, although they do not see the need now.
A. Right B. Wrong C. Not mentioned
5. It is required that labels placed on irradiated food or nearby bulk items such as vegetables and fruits should indicate irradiated ingredients.
A. Right B. Wrong C. Not mentioned
6. Restaurants can serve irradiated food bought directly from distributors without labeling it.
A. Right B. Wrong C. Not mentioned
7. The passage tells us that FDA approves irradiating food to some extent but irradiated food is not widely accepted.
A. Right B. Wrong C. Not mentioned

Soot and Snow：a Hot Combination
l New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow．According to a computer simulation，black soot may be responsible for 25 percent of observed global warming over the past century．
2 Soot in the higher latitudes 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．
3 Soot in areas with snow and ice may play all important role in climate change．Als0，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，NewYork．
4 Hansen found soot’s effect on snow albedo(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．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 forcing of the same magnitude，”Hansen noted．
6 Hansen cautioned．a(chǎn)lthough 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 f10r也e rest of this century．
7 The researchers found that observed warming in the Northern Hemisphere was 1arge 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．
