The lecturer talks about the opposite states of the ethanol fuel willbe a good replacement for traditional gasoline, and he gives demonstration to (你的意思是“给出证明”?是你自己发明的么?感觉没见过这样表达的,建议用“provide sufficient evidence”或者省去)argue against the three part of the passage.
First, ethanol fuel will product large volume of carbon dioxide to the atmosphere. It is a big problem to over(over可以这样搭配的么?) environment. But we must realize that when the plants are growing, the plantsneed carbon dioxide to take photosynthesis. It will reduce the gas of burning ethanol fuel in the future.
Second, animal's food and the material to produce the ethanol fuel are not much relevant. Because we can use some parts of plants that are not eaten by animals to produce the fuel. And it would not influence the source of food for animals.
Third, at beginning, to make the ethanol fuel cheaper may need the government subsidize. But it won't be a long term. The increase of production will lead the price of ethanol fuel to drop. Research show that the price will drop probably by forty percent. 不错不错,结构清晰,语句挺流畅的。 不过缺点很明显啊,你还没有了解综合写作的要求。 我觉得,你没有明确指出哪些是阅读的观点、哪些是讲座的观点。我对综合写作的理解是:阅读观点+讲座观点+讲座细节+阐明讲座与阅读观点的关系(抵触?or 同意?)。此外,要多用从句什么的,你文章句式太简单了,就算阐明了上述几点,不能得高分的。 建议你先看看几篇TPO范文再动笔,继续努力吧!
