TPO 22

先来看看阅读材料:

Ethanol fuel, made from plants such as corn and sugar cane, has been

advocated by some people as an alternative to gasoline in the United States.

However, many critics argue that ethanol is not a good replacement for gasoline

for several reasons.

译文:乙醇燃料是从玉米以下是或者甘蔗之类的植物中提取的。在美国,一些人提倡使用乙醇燃料来代替汽油。然而,很多评论家认为一些原因使得乙醇燃料不是良好的汽油替代品。

First, the increased use of ethanol fuel would not help to solve one of the

biggest environmental problems caused by gasoline use: global warming. Like

gasoline, ethanol releases carbon dioxide into the atmosphere when it is burned

for fuel, and carbon dioxide is a greenhouse gas: it helps trap heat in the

atmosphere. Thus, ethanol offers no environmental advantage over gasoline.

译文:首先,使用汽油带来的最大的问题之一是全球变暖,而对于乙醇燃料使用的增加并不能解决这个问题。同汽油一样,乙醇燃烧后向大气释放二氧化碳,而二氧化碳是温室气体。它会保持大气层内的温度。因而,相对于汽油来说,乙醇并没有环保优势。

Second, the production of significant amounts of ethanol would dramatically

reduce the amount of plants available for uses other than fuel. For example,

much of the corn now grown in the United States is used to feed farm animals

such as cows and chickens. It is estimated that if ethanol were used to satisfy

just 10 percent of the fuel needs in the United States, more than 60 percent of

the corn currently grown in the United States would have to be used to produce
