13、一段第一句Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory.（研究人员已经确定，当人们动脑时，大脑中会发生化学变化，使其在注意力和记忆等认知领域更有效地发挥作用。）和第二段第一句People will be alert and receptive if they
14、are faced with information that gets them to think about things they are interested in.（当人们面对的信息能让他们思考自己感兴趣的事情时，他们会变得警觉和容易接受。），说明认识健康的人大脑在注意力和记忆等感知区域的活动更加增强，变得警觉和容易接受。因此C选项“大脑是警觉的容易接受的”正确。A选项“能记住大量信息的人”，B选项“具有高度智慧的人”，D选项“善于辨别不同声音的人”在文中均没有提及，所以A, B, D错误。2.客观细节题。由题干可以定位到文章第三段最后一句Fozard and others say
