　　What is blood? Blood is a thick, red fluid which carries oxygen, water and
food to all parts of the body. It keeps the body at the right temperature (温度) and
protects it from disease.
　　If you lose a lot of blood, you need new blood. You can receive new blood
from other people. This is called a blood transfusion (输送).
　　People can donate (捐献) blood at a Red Cross Blood Bank. People who
give blood are called blood donors (捐献者). Some people sell their blood but
many others donate it.
　　Donating blood doesn’t hurt you and it doesn’t take long. First a nurse take a
drop of blood from your finger and tests it. She does this to make sure that your
blood is healthy. Then you lie down on a bed and another nurse checks your
blood pressure (血压). After that the nurse puts a needle into a vein in your arm.
The needle is attached to a tube. The blood flows through the tube into a plastic
bag. After about 10 minutes, when the bag is full, the nurse takes the needle out of
your arm. You stay on the bed and rest for a few minutes. Finally you go into
another room and have something to eat.
　　For a healthy person, donating blood is not harmful or painful. But the
blood he or she donates may save someone's life.
