A grown-up(成年)person has ten or eleven pints(品脱)of blood(血液)inside his or her body．We can lose a pint of blood without feeling anything, but if we lose too much blood, we feel weak and cold．Our faces become pale(苍白)．We may die．This is what often happens when somebody is hurt in an accident, or a soldier is hurt in a war．Many people used to die in this way．But today they can be taken to hospital and given more blood．Almost at once they feel better．Their faces are no longer pale．They do not die．
Where does this blood come from?People who are healthy may donate blood(献血)to a blood to a blood bank so that it can be used to save people’s lives．When they go to donate blood, a special kind of needle(针)is put into the arm．It does not hurt．The blood runs through the needle and through a rubber tube(橡胶管)into a bottle or a bag．A pint of blood is taken this way．The person who has given blood drinks a cup of tea or coffee and rests for a few minutes．Then he feels quite well．And he may give his blood this way three months later．
A person who gives blood feels happy, because he knows that his blood will be used to save someone’s life．Perhaps one day he himself will need blood．
When you are older, you may give blood, too．But you can not do this until you are eighteen．

Good health is very important．Everyone should do all he can to stay healthy．Being in good health means having both body and mind in good order, free from illness and pain．
Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should．Food does many things for our bodies．It gives what we need for keeping good health．It gives us energy for work and play．No food gives everything we need．We should eat foods of different kinds．Having enough to eat is not the same as having the right food．
The water we drink helps wash away wastes formed inside our bodies．It also puts back the water we lose when we perspire(流汗)．Our bodies are actually more than half water．We must drink enough to replace what we lose．
We feel better and look better when we are clean．A bath every one or two days is a good rule for most of us．Brushing our teeth is important part of keeping clean．
Sleep is the best kind of rest．Growing children need more sleep than grown-ups．Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲劳)．
It has been useful to work for good health．Millions of years ago, people live only 20 years．Now people can live about 70 years．It has gone up 20 years just since the beginning of the present century．
