衡水金卷 2026届高二年级5月份学情调研英语答案

28.B【解析】推理判断题。根据第三段“Theymeasured mood and depression before and after eachclass using the Geriatric Depression Scale (GDS)(年抑郁量表)and conducted regular MRI scans.”可知，研究人员使用老年抑郁量表(GDS)在每节课前后测量情绪和抑郁，并定期进行MRI扫描。由此可推知，研究人员是通过前后对比来进行研究的。故选B。29.A【解析】细节理解题。根据第四段“We showedthat SCG's BOLD blood oxygen level dependentsignal decreases while dancing,which means the SCGwas not functioning as fast as it would if you haddepression”可知，SCG的BOLD信号下降，意味着大脑中与抑郁相关区域的异常活动减弱，也就说明患者的抑郁情绪得到缓解。故选A。
