托福归纳写作阅览资料： Ethanol fuel, made from plants such as cornand sugar cane, has been advocated by some people as an alternative to gasolinein the United States. However, many critics argue that ethanol is not a goodreplacement for gasoline for several reasons.
乙醇燃料是从玉米或者甘蔗之类的植物中获取的。在美国，一些人发起运用乙醇燃料来代替汽油。然而，许多评论家以为一些缘由使得乙醇燃料不是杰出的汽油代替品。 First, the increased use of ethanol fuelwould not help to solve one of the biggest environmental problems caused bygasoline use: global warming. Like gasoline, ethanol releases carbon dioxide intothe atmosphere when it is burned for fuel, and carbon dioxide is a greenhousegas: it helps trap heat in the atmosphere. Thus, ethanol offers noenvironmental advantage over gasoline.
首要，运用汽油带来的最大的疑问之一是全球变暖，而关于乙醇燃料运用的添加并不能处理这个疑问。同汽油一样，乙醇焚烧后向大气开释二氧化碳，而二氧化碳是温室气体。它会坚持大气层内的温度。因此，相关于汽油来说，乙醇并没有环保优势。 Second, the production of significantamounts of ethanol would dramatically reduce the amount of plants available foruses other than fuel. For example, much of the corn now grown in the United Statesis used to feed farm animals such as cows and chickens. It is estimated that ifethanol were used to satisfy just 10 percent of the fuel needs in the UnitedStates, more than 60 percent of the corn currently grown in the United Stateswould have to be used to produce ethanol. If most of the corn were used toproduce ethanol, a substantial source of food for animals would disappear.
第二，乙醇商品的很多添加会致使用于别的意图作物数量减少。比方，在美国许多的玉米都是用来作动物饲料来喂养牛和鸡。能够推测，假如乙醇只满意美国对燃料需求的10%，那么美国就要用如今玉米产值的60%用来制作乙醇燃料。假如把玉米产值的大多数用来出产乙醇燃料的话，那么牲畜首要的食物来历就不复存在了。 Third, ethanol fuel will never be able tocompete with gasoline on price. Although the prices of ethanol and gasoline forthe consumer are currentlyabout the same, this is only because of the help inthe form of tax subsidies given to ethanol producers by the United Statesgovernment. These tax subsidies have cost the United States government over $11billion in the past 30 years. If the United States government were to stophelping the producers in this way, the price of ethanol would increase greatly.
第三，乙醇燃料燃料在报价上永远无法与汽油竞赛。虽然当前对消费者来说，乙醇燃料和汽油的相差无几，可是只是因为美国政府以税收补助的方式补助乙醇燃料制作商。这个税收补助在过去的三十年花掉了美国政府110亿美元。假如美国政府中止以这种方式协助制作商，那么乙醇燃料的报价会大幅增加。 托福归纳写作阅览有些需求获取的观念是： - Main point: 乙醇燃料无法代替汽油 - Sub point 1: 焚烧乙醇燃料会排放二氧化碳，形成全球变暖 - Sub point 2: 制作乙醇燃料致使畜牧业缺少饲料 - Sub point 3: 乙醇报价过高，依靠政府补助 最后，托福代报名预祝大家考试顺利
