If you don’t use your arms or legs for some time，they become weak．When you start using them again，they will slowly become strong again．Everybody knows that．But many people do not know that the use of our 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．But when someone says that his memory is poor，it is because he does not give it enough chance(机会)to become good．

   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 are to be blamed，and only few of them know that it is his own fault．

   Some people who can’t read or write sometimes have better memories．Because they can’t read or write，they always have to make their memories work，This is to remember the days，names，songs，and stories in their mind．

   So if you want to have a good memory．please practice it．

    If you do not use your arms or 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 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 are to blame，and few of us know that it is just his own fault．Have you ever round 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 down in a little notebook．They have to remember days，names，songs and stories，so their memory is the whole time being exercised．So if you want to have a good memory，learn from the people：Practice remembering．
