If you do not use your arms or your legs for some time, they 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 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 chances to become strong.
If a friend says that his arms and legs are weak, we know that it is not his own fault (错误) . But if he says that he has a poor memory, many of us think 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 and they have to remember things; they cannot write them down in a little 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

如果你长不时常活动手和腿脚，它们就会变得虚弱；你又开始活动的时候，它们会慢慢恢复强壮，这每个人都知道。然而很多人似乎并不知道我们的记忆力也是如此变化的。
当有人说他记忆力很好时，实际上他在练习记忆从而保持良好的记忆力。当另外一些人人说他记忆力不好时，事实上他没有足够的机会让他的记忆力变得良好。
如果一个朋友说他的手和腿脚不够强壮，我们知道这不是他的错；但是如果他说他的记忆力不好，大部分人都认为这就是他的错了。
你曾经遇到过这样的人吗？他们不能读不能写，但是有很好的记忆力。就是因为他们不能读写只能记忆，需要记忆很多日期，名字，歌曲和故事；所以他们的记忆力一直活跃。
所以如果你想拥有良好的记忆力，向他们学习：练习记忆.
