ethanol不是gasoline的好替代品。

1、并不会改善global warming

2、减少植物

3、价格没有优势，虽然现在便宜，但是是因为政府补贴。一旦停止补贴就贵

听力

文章中ethanol不好的理由都不convincing，也就是说ethanol实际上是gasoline的好替代品

1、可以改善global warming。它并不会像文章说的增加二氧化碳。它虽然也产生二氧化碳，但是正如文章说的，它可以由corn这样的植物生产，而植物本身absorb二氧化碳carbon dioxide，总而减少空气中二氧化碳。

2、可以由动物们不吃的植物产生

3、ethanol如果有现在的三倍的生产量，价格可以减少40%。

范文

The professor in the lecture definitely believes that ethanol is a good alternative of the gasoline. His view point is definitely opposite to the statements made in the reading passage. Actually, he finds the statements made by the reading passage unconvincing.

On one hand, the professor points out that burning ethanol will not add to global warming as the statement mentioned in the reading passage. Although burning ethanol will release carbon dioxide into the atmosphere, the growing process will counteract the effort by absorbing carbon dioxide in the air. Therefore, the professor finds the first statement in the reading passage unconvincing.

On the other hand, the professor indicates that producing ethanol will not reduce the amount of food for animals. In fact, the professor says we can produce ethanol by using cellule, which will not be eaten by animals. Therefore, the amount of plants for other use will not decrease as the reading passage mentions.

What’s more, the professor counters that ethanol will compete with gasoline in terms of price. The professor indicates that the continuing support for ethanol will make the production of ethanol increase, and thus the price of ethanol will decrease in the future. Under this circumstance, the third statement made by the reading passage is unconvincing.
