在线模考-TPO2-阅读第二篇(Desert Formation)中的句子简化题-原文句子是:The extreme seriousness of desertification results from the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process.我觉得这句话的因果关系是沙漠化来源于人类的活动,原因是人的活动,结果是沙漠化,但是答案选择的是A,意思就是沙漠化在影响人的活动,这如何解释?
