问题 Choose TWO letters, A-E
What TWO problems does the report focus on?
A air pollution
B soil erosion
C overgrazing
D forest exploitation
E water pollution

选项

答案B

解析 原文中说“I am personally very interested in soil erosion,so I knew that I definitely wanted to focus some of the report on this area”,因此报告要研究的有soil erosion,选B。定位至第二处“but the impacts of forest exploitation are far more devastating and very little research has been carried out on this subject,so I decided that this should also form some focus for the report”,可知forest exploitation(森林开采)方面的研究也将成为报告中的一个关注点,故选D。
