帮我改一篇托福综合写作吧 The author of the passage argues that the ethanol fuel is not a good replacement of fossil fuel. In the listening material, however, the professor shows a completely different view that ethanol fuel is an ideal alternation. The professor casts doubt on the idea of the writer from three aspects. In the first place, the lecturer disagrees with the first point in the article, that using ethanol fuel can not solve global warming. The lecturer insists that ethanol fuel can reduce the amount of carbon dioxide released and, in turn, solve the global warming problem. It is true that burning ethanol fuel can also release carbon dioxide, but when plants grow, for example corns, they remove carbon dioxide from atmosphere. The process of absorbing and releasing can counteract change of the carbon dioxide in the atmosphere. Hence, this is the first part where the listening contradicts the reading. In the second place, the author believes that manufacturing ethanol fuel will take up resources of animals' food. The professor, in contrast, presents a contradictory opinion that producing ethanol fuel does not use resources of animals. The raw material of ethanol fuel is abundant in the seed walls, which are not eaten by any animals. This is another aspect showing that the listening material objects to the point in the reading passage. In the last place, the third point in the reading material is that the price of ethanol fuel without government subsidies is high. The speaker directly challenges it by presenting a confliction point that the price will be lowered if the production scale increases. The professor elaborates that the ethanol fuel will no long need the help of government because when production goes up, the prices will decline. Also, a research says that when the production becomes three times higher, the price would be forty percent lower. Again, the contents displayed in the reading passage are entirely rejected by the professor.
