People often underestimate the effect exercise can have on mental acuity.
是否是 have an effect on...的倒装句?
答
不是倒装句.此句完整的应该是People often underestimate the effect（that/which） exercise can have on mental acuity.这是一个定语从句,the effect 是定语从句先行词,在从句中做have的宾语,所以引导词that 或者w...People often underestimate the effect（that/which exercise can have on mental acuity.）这里的have on作何解？have an effect on 是固定搭配，意思是 对... 有影响、有作用
