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 definitelywanted 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 beencarried 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。
