C.analyze the difference between different age groups in the loss of memory
D.reveal the decrease in mental ability of the young adults as well as the older adults请帮忙给出正确答案和分析,谢谢!

参考答案

正确答案:D
解析:本题为主旨题。要确定本文的目的是什么。选项A.introduce effective ways to improve memory虽然在文章中有所提及,但并不是本文的主要目的;选项B.emphasize the importance of exercising the brain意为“强调锻炼大脑的重要性”,虽然文章提到对大脑的锻炼,但并没有用较大篇幅强调其重要性;选项C.analyze the difference between different age groups in the loss of memory意为“分析不同年龄组在记忆减退方面的差异”,而此文目的并非在此,因此不正确。文章主要说明了“年轻人从20多岁开始记忆力就会逐步减退”这一主题。因此选项D.reveal the decrease in mental ability of the young adults well as the older adult才是本文的主题。
