Memory is the ability to remember things. A good memory can help us do better in school, such as language learning. A few people are born with amazing memories, but most people need to improve their memories by practising. Here are some secrets about memories.
We can still remember things that happened in our childhood, but not those last week. In fact, if the things have strong connections with our feelings in our mind, we can remember them longer. When things happen for the first time, children often have strong feelings. Also, parents tell us the interesting or funny stories from our childhood again and again. As a result, we remember them much better.
It's natural for common people to forget the new words which they learnt yesterday. Hermann Ebbinghaus wrote a book called Memory and showed a famous forgetting curve. According to him, the quickest loss of memory happens during the first two days after learning. That means going over what we've learnt during this time can help us remember the information.
A 15-year-old sometimes forgets things, but that doesn't mean his or her memory is getting worse. Our memory gets the top at the age of 25. At that point, we can remember over 12,000 pieces of information in a minute. But after this age, the brain starts to get smaller. By middle age, our memory is much worse than when we were young.

【分析】
本题为科普类阅读理解题，需结合原文内容逐一分析各小题：
1. 第5题：定位原文第二段关于童年记忆的描述，提取关键信息，判断对应选项；
2. 第6题：根据原文中艾宾浩斯遗忘曲线的特点（遗忘先快后慢），匹配对应图像；
3. 第7题：定位最后一段内容，逐一核对选项与原文表述是否一致；
4. 第8题：梳理各段落主旨，划分文章结构。
【解析】
5. 原文第二段提到“if the things have strong connections with our feelings in our mind... children often have strong feelings... parents tell us the interesting or funny stories from our childhood again and again”，对应b（有强烈感受）和d（多次听到），故选B。
6. 原文第三段指出艾宾浩斯遗忘曲线的特点是“the quickest loss of memory happens during the first two days after learning”，即遗忘先快后慢，观察图像：A为匀速下降，B为上升，C为先快后慢的曲线，D为后期快速下降，符合的是C，故选C。
7. 最后一段明确“Our memory gets the top at the age of 25”，对应A选项；B选项与原文“By middle age, our memory is much worse than when we were young”矛盾；C选项“only”表述绝对，原文未说明唯一原因；D选项是25岁能记12000条信息，并非孩子，故选A。
8. 段落主旨：①段引出记忆话题；②段讲童年记忆好的原因；③段讲艾宾浩斯遗忘曲线；④段讲记忆随年龄的变化，结构为①/②③④，故选D。
