2．When you do not use your arms or your legs for some time，they will become weak．When you start using them again，they slowly become strong again．Everybody knows that．Yet many people do not seem to know that memory （记忆 ） works in the same way．
When someone says that he has a good memory，he really means that he keeps his memory in practice by using it．When someone else says that his memory is poor，he really means that he does not give it enough chance to become strong．
If a friend says that his arms and legs are weak，we know that it is his own fault （过错）．But if he tells us that he has a poor memory，many of us think that his parents may be blamed （责备 ），and few of us know that it is just his own fault．Have you ever found that some people can't read or write but usually they have better memories？This is because they cannot read or write but they have to remember things，they cannot write them down in a small notebook．They have to remember days，names，songs and stories，so their memory is being exercised the whole time．
So if you want to have a good memory，learn from the people：practice remembering things in a way as other people do．

解答 48C 细节理解题．根据短文第一段的意思可知，作者用胳膊或腿给我们做类比，如果我们不经常的使用他们，他们就会变弱；当你又重新使用他们的时候，他们又会变得强壮．我们的记忆力也是一样的．由此可知，如果我们不使用我们的记忆力，我们就不会有好的记忆力．故选：C．
49A 细节理解题．根据短文第一段中When you do not use your arms or your legs for some time，they will become weak．When you start using them again，they slowly become strong again可知，当我们一段时间不用我们的胳膊或腿的时候，他们就会变弱．当你重新使用他们的时候，他们又会慢慢地变强．故选A．
50B 推理判断题．根据memory （记忆 ） works in the same way．可排除A；根据This is because they cannot read or write but they have to remember things，they cannot write them down in a small notebook．可排除C；根据When someone says that he has a good memory，he really means that he keeps his memory in practice by using it．可排除D；根据When someone else says that his memory is poor，he really means that he does not give it enough chance to become strong．可知B是正确的．故选：B．
51D 细节理解题．根据短文中But if he tells us that he has a poor memory，many of us think that his parents may be blamed （责备 ），and few of us know that it is just his own fault．可知，如果你的朋友告诉你他的记忆力不好，我们很少有人会知道这其实是他自己的错．故选：D．
52A 主旨大意题．这篇短文中作者想要告诉我们，我们的记忆力就像我们的胳膊和腿一样，需要经常使用，给它足够的练习，这样我们才能有好的记忆力．作者还告诉了我们应该怎样提高我们的记忆力．故A选项怎样有好的记忆力最符合文意．故选：A．
