Paragraph 1 is marked with ►
本题根据题干找到高亮部分：This recent increase in fires has resulted partly from climate change (the recent trend toward hot, dry summers) and partly from human activities, for complicated reasons that foresters came increasingly to understand about 30 years ago but whose relative importance is still debated. 本句大意是：最近森林火灾的增长一部分是气候变化(夏天变得更干更热)和人类活动的原因，虽然这些复杂原因谁更重要还在争论中。选项D是本句的同义转述。选项A说人类活动导致气候变化，错误;选项B说森林学家还在争辩气候变化算不算一个导致森林大火的原因，错误，只是在争辩谁更重要;选项C说在夏天的森林大火增多，本句没有具体说到在哪个季节森林大火多，错误。选择D。
