参考解析
解析： 第三段共三句话，第一句讲了短期记忆，第二、三句讲了长期记忆，因此本段的主题应该是对两者进行对比。
第四段先讲必须通过学习使大脑获得信息，学习策略不经常使用就要生锈。中间举了学生学习为例。最后一句话是本段结论性的话，“受教育越多的人，一生中记忆技巧就越有效，这就不足为奇了”。可见本段主题是讲学习策略与有效记忆技巧之间的关系的。
第五段讲的是老年人的记忆，其中讲到思维活跃的老人与思维不活跃的老人之间有明显差别，最后一句话仍然是结论性的，“脑力劳动可以使你的学习策略保持良好的状态，并有助于记忆力充分发挥作用”。因此，本段的主题应是“保持思维活跃的重要性”。
本段一开始就说，“健全的长期记忆的第二部分就是记忆力，即储存你所学知识的能力。”可见本段主题已很鲜明了。
第六段第一句中的“the ability to store what you have learned”就是它前面的名词“retention”的同位语，只是本题将ability换成capacity而已。
文章最后一句说“实际上，年老似乎对遗忘没有什么影响，因为遗忘的发生率年轻人与老年人是一样的”，可见本题答案应为A。
根据第二段第二句对记忆的分类法，其中very long-term memory的记忆时间是over a life time，故本题答案应为E。
根据第五段第二句及第三句，从“Giving the brain a daily workout... helps your memory to function at full capacity,”可以看出本题答案应为B。
