名牌学校分层周周测系列答案【题目】
Many Americans concerned about air pollution are demanding cleaner and cheaper supplies of energy. The demand has resulted in increased research about ethanol fuel. Ethanol is an alcohol that can be mixed with gas. It burns up most of the pollutants in gas. It replaced some of the chemicals that are known to cause cancer.
Some experts say that in the future ethanol will replace some of the oil imported into America. Today ethanol is less than one percent of the total American fuel supply. The head of the National Corn Growers Association, Kieve Hars, says ethanol will provide twenty five percent of the fuel supply by 2010. The organization is involved in the production of ethanol because it can be made from corn.
One company in American Midwest says it is starting to produce ethanol because of demands from people and from the government. The Congress approved the Clean Air Act in 1990. The company says this means the market for ethanol will expand. The company is a major producer of corn starch (淀粉) that can be used to make ethanol.
At Texas University, Professor Mark Holzapple produces ethanol from materials found in solid waste. He has developed a way to turn materials like paper into simple sugar. He then uses yeast (酵母) to turn the sugar into ethanol. Professor Holzappple says two hundred liters of ethanol fuel can be produced from one ton of solid waste.
A professor at the University of Arkansas, John Geddie, is exploring another way to make ethanol. He is using acids on paper material. He says a large factory could produce ethanol from waste paper about the same cost of that of gasoline.
Environmentalists support the use of ethanol because it turns waste into a useful product. Professor Holzapple says law makers in industrial nations need to support the development of this renewable fuel of the future.
