If a person loses a lot of blood, he will bee ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong! When doctors understand how blood moves inside the body, they try ways of giving blood to people who need it. They take blood from healthy people and give it to people who need it. This is called a ―blood transfusion‖. The blood goes from the arm of the healthy person into the arm of the sick person. But there are two problems. First, it does not always work. Sometimes people die when they have a blood transfusion. Also we do not all have the same kind of blood. There are four groups – O, A, B and AB.

To give blood of the right kind, doctors have to find a person of the right blood group. Often they cannot find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. By making the blood very cold, doctors find they can keep it for a very long time. In the end they find a way of keeping blood for a very long time. We call a place where we keep money a ―bank‖. We call a place where we keep blood a ―blood bank‖. One day, when you grow up, you may decide to give blood to a ―blood bank‖. In this way you may stop someone from dying. Or perhaps, one day, you may bee ill, and you may need blood. The ―blood bank‖ will give it to you. ( ) 52. People may die if they_______________. A. lose a lot of blood B. cut their skin C. drink others’ blood D. get blood from healthy people ( ) 53.
