选项 A. genre
B. functions
C. circumstances
D. criterion
答案 B
解析 本题测试考生根据上下文对词义的判断选择能力。Genre种类；风格；functions功能，作用；circumstances情况；环境；criterion标准。 此处填入cognitive（认知的)修饰的名词，作can significantly improve（可以大幅提高)的宾语，即“正确的大脑锻炼可以提高认知的……”。本题可用排除法，将四个选项—一代入。A项genre代入指“认知的种类”，语义搭配不当，可排除；C项circumstances指的是 客观“情况”或“环境”，而主观的大脑活动不可能改变客观事实更不可能改变认知的标准，故C项和D项也不对； B项functions意为“功能，作用”，符合此处语境，表示适度的脑部锻炼可以明显提高基本认知功能。
