参考答案
正确答案：A
解析：Listen again to part of the talk. Then answer the question.
"In the past, before we understood the role that fire plays in the natural life cycle of our forests, our goal was to prevent or contain all forest fires. For almost ninety years, our land management agencies tried to eliminate fires. In many cases, we protected the trees, but at the expense of the forest community."
What does the instructor mean by this statement:
"In many cases, we protected the trees, but at the expense of the forest community."
The instructor means that fire prevention has actually damaged the forest ecosystem. The previous forest policy was to eliminate forest fires. Preventing fires saved trees but at the expense of the forest community because periodic fires are natural and benefit the forest as a whole. (2.4)
