Target text（文章正文）:

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.
