  在美國,一些人提倡使用乙醇燃料來代替汽油。然而,很多評論家認為一些原因使得乙醇燃料不是良好的汽油 替代品。托福TPO22綜合寫作的材料就乙醇燃料是否是很好的汽油替代品進行了分析。下面是小編整理的材料和范文,歡迎閱讀!

  托福TPO22綜合寫作范文

  The reading and listening materials have a conflict of opinions about ethanol fuel. The writer believes that it is not a good alternative to gasoline, which is contradicted by the following lecture.

  Firstly, the writer claims that ethanol fuel fails to solve the environment pollution since it also releases carbon dioxide when burned. However, the speaker opposes the claim by saying that ethanol fuel is made of plants like corn, which absorbs carbon dioxide from the air as part of its nutrition. So the process of growing the plant counteracts the release of green house gas emission.

  Secondly, the writer states that the production of ethanol fuel would lead to a decline in source of food for farm animals, while the lecture views this issue from an opposite angle. According to him, ethanol fuel is made of cellulose, which is not eaten by animals. As a result, the amount of animal food won't be reduced at all.

  Third, the passage argues that ethanol fuel is less competitive than gasoline in terms of price because it is still relying on government's subsidies. By contrast, in accordance with the speaker, the reading's claim does not hold water. It will no longer be necessary for government to subsidize ethanol fuel because an increase in demand will result in an increase in production, which gives rise to a drop in its price. According to a study, if the production of ethanol fuel is three times greater than it is now, the price will drop by 40%.

  托福TPO22綜合寫作閱讀材料:

  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.

  乙醇燃料是從玉米或者甘蔗之類的植物中提取的。在美國,一些人提倡使用乙醇

  燃料來代替汽油。然而,很多評論家認為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.

  首先,使用汽油帶來的最大的問題之一是全球變暖,而對于乙醇燃料使用的增加 并不能解決這個問題。同汽油一樣,乙醇燃燒后向大氣釋放二氧化碳,而二氧化 碳是溫室氣體。它會保持大氣層內的溫度。因而,相對于汽油來說,乙醇并沒有 環保優勢。

  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 ethanol. If most of the corn were used to produce ethanol, a substantial source of food for animals would disappear.

  第二,乙醇產品的'大量增加會導致用于其他目的作物數量減少。比如,在美國很 多的玉米都是用來作動物飼料來喂養牛和雞。可以推測,如果乙醇只滿足美國對 燃料需要的 10%,那么美國就要用現在玉米產量的 60%用來制造乙醇燃料。如 果把玉米產量的大部分用來生產乙醇燃料的話,那么家畜主要的食物來源就不復 存在了。

  Third, ethanol fuel will never be able to compete with gasoline on price. Although the prices of ethanol and gasoline for the consumer are currently about the same, this is only because of the help in the form of tax subsidies given to ethanol producers by the United States government. These tax subsidies have cost the United States government over $11 billion in the past 30 years. If the United States government were to stop helping the producers in this way, the price of ethanol would increase greatly.

  第三,乙醇燃料在價格上永遠無法與汽油競爭。雖然目前對消費者來說,乙醇燃 料和汽油的相差無幾,但是只是因為美國政府以稅收補貼的形式補助乙醇燃料制 造商。這個稅收補貼在過去的三十年花掉了美國政府 110 億美元。如果美國政 府停止以這種形式幫助制造商,那么乙醇燃料的價格會大幅升高。

  托福TPO22綜合寫作聽力材料:

  Ethanol actually is a good alternative to gasoline although you just read three reasons why it is not a good alternative. Not one of these three reasons is convincing.

  雖然閱讀部分說乙醇燃料不是汽油很好的代替品,但是事實上是可以很好代替汽

  油的。閱讀部分給出的三個理由都是沒有說服力的。

  First, the increased use of ethanol will not add to global warming. It is true that when ethanol is burned, it releases carbon dioxide into the atmosphere. But as you read, ethanol was often made from plants such as corn. Well, the process of growing the plants counteracts this release of carbon dioxide. Let me explain. Every growing plant absorbs carbon dioxide from the air as a part of its nutrition. So, growing plants for ethanol production actually removes carbon dioxide from the atmosphere.

  首先,提高對乙醇燃料的使用不會導致全球變暖。誠然,燃燒乙醇燃料的時候是 會向空氣中排放二氧化碳。但是,就像在閱讀部分看到的,通常來說乙醇燃料是 由玉米之類的作物制造的。恩,這些作物生長的過程中可以抵消掉乙醇燃料燃燒 所釋放的二氧化碳的。我來解釋一下。所有作物在生長的過程中都會吸收空氣中 的二氧化碳作為養料。所以,為制造乙醇燃料而種植的作物事實上可以吸收乙醇 燃料排放到空氣中的二氧化碳。

  Second, large scale production of ethanol does not have to reduce the source of food for animals. That is because we can produce ethanol using cellulose. Cellulose is the main component of plants’ cell walls, and you find most cellulose in those parts of plants that are not eaten by animals. So, since we can produce ethanol from the plant parts that are not eaten, the amount of animals feed that is available will not be reduced.

  第二,大量生產乙醇燃料不會減少畜牧業的飼料供應。這是因為我們用纖維素制 造乙醇燃料。纖維素是植物細胞壁的主要組成成分,而且多數作物富含纖維素的 部分都是家畜不食用的。所以,鑒于我們是使用家畜不食用的部分來制造乙醇燃 料的.,那么家畜可使用的飼料不會減少。

  Third, in the future, ethanol will be able to compete with gasoline in term of price. It is true that the government subsidies make up ethanol is cheaper than it would normally be, but this support would not always be needed. Once enough people start buying ethanol, ethanol producers will increase their production of ethanol. Generally, increased production of a product leads to a drop in its price, so the price of ethanol will go down as more of it becomes available. Study shows that if ethanol production could be three times greater than it is now, the cost of producing a unit of ethanol would drop by forty percent.

  第三,在未來,乙醇燃料可以在價格上同汽油競爭的。確實,現在政府的補貼政 策使得乙醇燃料的價格比實際要低,但是這樣的補貼政策不需要一直存在。一點 有足夠多的人購買乙醇燃料,那么乙醇燃料的制造商將會更多地生產。 一般來說,對某產品的生產增多會導致價格下降,所以當乙醇燃料燃料的產量增 加之后,價格也會隨之下降。研究表明如果乙醇燃料產品的產量增加三倍, 那么每個單位乙醇燃料的價格將會下降 40%。
