问题     The atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E. O. Wilson, a biologist at Harvard, calls the depletion(枯竭、耗尽)of rain forest areas "the greatest extinction since the end of the age of dinosaurs(恐龙)".
    Unlike some environmental issues, rain forest depletion has fortunately received significant public and media attention. Despite the opposition to the cutting down of rain forests, the problem continues. Every year, Brazil chops down one area of forest the size of the state of Nebraska. In addition to the Amazon’s rain forests, many other forests are being cut down as well. In Indonesia, Zaire, Papua New Guinea, Malaysia, Burma, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain forests that were once great have been lost.
    According to some estimates, 50 million acres of rain forest are cut down every year. The United Nations says the figure is closer to 17 million acres. The World Wildlife Fund says that every minute, 25 to 50 acres are cut or burned to the ground.
    The world’s growing population has been a primary reason of rain forest destruction. More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would limit the destruction of the rain forests.
The word "chops down" in the second paragraph means______.

选项 A、clears
B、makes rooms for
C、destroys
D、cuts down

答案D

解析 本题问:第二节里的“chops down”的意思是——。这是一道语义题。根据上句提到:Despite the opposition to the cutting down of rain forests,the problem continues.Everyyear,Brazil chops down one area of forest…,我们可以推知这是“同义再现”——即:同一篇文章围绕一个主题,作者难免会反复使用同一个词语或同义词语,因此选D。砍例,砍伐一般不会有错。其它选项:A.清除B.为……腾出地方C.毁坏。
