　　托福综合写作范文Sample answer:

　　In the lecture, the professor refutes against the view raised in the reading that algae fuel is problematic, and he think it is very feasible.

　　Firstly, the reading holds that the planting of algae wastes farmland and usable water, which may lead to food shortage. However, the professor refutes that Algae are very adaptive and can survive anywhere. They can even grow in dirty water and unfertile land. They will not compete with the crops for the growing land.

　　Secondly, the reading claims that equipment for extracting oil from algae is expensive. But the professor disagrees with this by suggesting that the growing speed of algae is very fast, almost 20 times of that of the corn. They can be gathered every week, which means the cost can be quickly compensated.

　　Finally, in the reading passage, it indicates that algae require a large amount of carbon dioxide provided by farmer intentionally to grow. When the unused carbon dioxide is released into the atmosphere, it is detrimental to the environment. In contrast, the professor holds that carbon dioxide can be gathered from factories, which in turn tackles the problem of waste gas emission and alleviate the environmental problem.
