(B)

        A grown-up person has ten or eleven pints (品脫) of blood inside his or her body. We can lose a pint of blood without feeling anything. But if we lose a great deal of blood,we feel weak and cold. Our faces become very white. We may die.

        This is what often happens when somebody is hurt in an accident or a soldier is hurt in a fighting. Many people used to die in this way. If they are given enough blood at once,they'll feel better. Their faces will become red again. They won't die.

        Where does this blood come from? People who are healthy give some blood so that it can be used in this way. Every three months they can go to a place where blood is collected. A special kind of needle is put into the arm. It does not hurt. The blood runs through the needle and through a rubber tube (管) into a bottle. A pint of blood is taken away. Then the person who has given the blood drinks a cup of tea or coffee. He sits for a few minutes. Then he feels quite well and goes off. Three months later he comers back and gives another pint.

        A penson who gives blood in this way feels happy. 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 decide to give blood in this way. But you can't do this until you are eighteen.
