TPO22修改
The lecturer and the reading passage hold opposite opinion(貌似opinions吧) toward whether or not the ethanol fuel is the good replacement for gasoline. The lecturer illustrate(小错误哦illustrates) the benefit of ethanol fuel in three aspects.
First, the reading mentions that burning ethanol will create carbon dioxide, accelerating the global warming. However, the lecturer diffuses the point by saying that using ethanol will not add to global warming, because the process of producing ethanol, growing the plants, can absorb carbon dioxide.(这句话不通,我知道你要说植物成长过程会吸收CO2,但你前面的the process of producing ethanol会吸收CO2? 属逻辑不当) In return, carbon dioxide will be decreased if people use ethanol as the replacement of gasoline.
Second, the reading passage points that the amount of food for farm animals will be sacrificed to the large production of ethanol, while the lecturer opposes the point as nonsense. He says that ethanol is produced largely by the part of the plant named cell walls, which is inedible for farm animals. Given to this reason, the amount of food for farm animals will not diminished.(此段写得很流畅,不错!)
Third, the reading passage indicates that the price of ethanol is too high so that(so that后面可以直接接残句? 后面应该为完整句子吧.建议加个主语在后面) unable to compete with gasoline. Nevertheless, the lecturer rejects that although it is true the tax policy brings advantages to ethanol use, this protection action would not always be needed because with the large production of ethanol, the marginal cost (呵呵,边际成本这次用的很好,不错~)will go down. Related research indicates(建议加that) if the production of ethanol goes up to 4 times as what it is now, the price will plummet forty percent off.(plummet off词组很不错)
换词恰当,除了小小粗心,整体不错,看得出基础扎实.继续加油~~~ 很棒唷! |
