The lecturer contends that prescribed burns prevent larger forest fires. This directly contradicts the reading passage’s claim that there are more disadvantages than advantages.
First, in spite of the concerns some people have, only a few animals die from the burns; there is enough time for animals to escape. Moreover, the professor cites the example of Yellowstone National Park, where animals have no difficulties finding new habitats because of the park's huge size. This refutes the reading passage’s claim that forest animals die from prescribed burns and that even if they manage to survive, they have a hard time because of the competition for food in their new territory.
On top of that, the lecturer says there has been a misunderstanding about the environmental damage of prescribed burns. It is true that prescribed burns produce smoke; however, the amount of smoke is much less than the amount of smoke generated during major forest fires. This rebuts the reading passage’s claim that since many prescribed burns take several days, smoke coming from the burning causes air pollution. Finally, prescribed burns are deliberately carried out. The forest officials put a lot of thought and efforts into the burns before they intentionally set a forest on fire; accordingly, it is less feasible that the forest officials would conduct the burns if conditions are not suitable. This contradicts the idea mentioned in the reading passage that prescribed burns can change into major forest fires by spreading unexpectedly.

Do you agree or disagree: the most effective way for governments to encourage energy conservation is to increase the price of gasoline and electricity?
范文：(不同意)
In such a scientific-technologically developed society, energy has played an indispensable and dominant role in aspects of life, whatever in personal living or corporate expansion. However, with the rapid decline in the amount of the energy or recourse resulting from increasing demand as well as overly exploitation, it is imperative that government take measures to conserve the energy available. For example, increasing the cost of gasoline and electricity will admittedly control the use of both for a majority will not purchase or waste them as before, but it is not the only way due to some potential drawbacks in the long run.
For one thing, it will create a path for some commercial producers to make profits from the price-raising illegally when they are keen on the sole material benefits instead of the initial motive of the government. Energy, whose consumption has accounted for a big proportion in the national revenue, is always a hot issue in many profit-oriented companies. For instance, some gasoline companies will expand their exploitation area for larger inventories, from which they can get greater profits once the price of the products are increased. They will also force their employees to work excessively with disregard to safety. Doing so can not only conserve the energy as planned, but also bring some negative influenced on the social life.
For another, the increase in the energy may cause a financial burden for those relying on the resource, individually or corporately. If the strategy is carried out, some companies will face great difficulty in affording the energy, and consequently they cannot continue their production without resource provision. Neither can some families in some poverty-stricken areas. One of my relatives, living in a less developed village, is striving to save the money on the electricity or gas. Suffering from the pressure of tuition of his children, he has to try to live an economical life. Thus the increase in the price of electricity will inevitably become an obstacle in such occasions.
In conclusion, in spite of the possible effectiveness in the energy conservation, the cost rising will lead to some illegal cases or financial burdens to some poor ones at the same time. If there are some more complementary alternatives, such as to enhance the public awareness to conserve the energy actively, the goal of the government will be fulfilled in a balanced way.
