①Memory is the ability to remember things. A good memory can help us do better in school,such as language learning. Here are some secrets about memory.
②In fact,if the things have strong connections with our feelings in our mind,we can remember them longer. As a result,we remember them much better.
③It'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(曲线). According to him,memory is lost the most quickly at the beginning of learning. That means going over what we learnt can help us to remember well.
④A 15-year-old sometimes forgets things,but that doesn't mean his or her memory is getting worse. Our memory is the best at 25 years old. At that point,we can remember up to 200 pieces of information in a second. But after this age,the brain starts to get smaller. By middle age,our memory is much worse than when we were young.

46题：定位原文第④段“Our memory is the best at 25 years old.”，A选项“没人有好记忆”无依据；B选项“25岁后脑变大”与原文“after this age,the brain starts to get smaller”矛盾；D选项“学习结束时记忆丢失最快”与原文“memory is lost the most quickly at the beginning of learning”矛盾，故选C。
47题：定位原文第④段“At that point,we can remember up to 200 pieces of information in a second.”，直接对应选项B。
48题：原文第①段点明“Here are some secrets about memory.”，后续段落均围绕记忆的秘密展开，故主旨为记忆的秘密，选B。
49题：原文结构为“总-分”：①段总述记忆的秘密，②③④段分述不同的记忆相关内容，对应选项D的结构，故选D。
