If you do not use your arms or your legs for some time, they become weak; when you start using again, they slowly become strong again. Everybody knows this, and nobody would think of questioning the fact. ____小题1:____ When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously or unconsciously. When someone else says that his memory is poor, he really means that he does not give it enough opportunity to become strong. ____小题2:____ One of them exercises his arms and legs by playing tennis, while the other sits in a chair or a motor car all day.
If a friend complains that his arms are weak, we know that it is his own fault. ____小题3:____, many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is just as much his own fault as if it was his arms or legs that were weak. Not all of us can become extremely strong or extremely clever; but all of us can, if we have ordinary bodies and brains, improve our strength and our memory by the same means––practice.

C.But if he tells us that he has a poor memory

E. When someone else says that he is poor in the health
F. Why is this?
