阅读理解。     When you cut your skin, you bleed (流血). If a person loses a lot of blood (血), he will become ill and
may die. Blood is very important. People have known that. At one time, some people even drank blood
to make them strong!
     When doctors understand how blood goes around inside the body, they try ways of giving blood to
people who need it. They take blood from the healthy people and give it to people who need it. This is
called "blood transfusion". The blood goes from the arm of the sick person.
     But there are two problems. First, it does not always work. Sometimes people die when they have
blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four
groups - O, A, B and AB. We all have blood of one of these groups. They also find that they can give any
kind of blood to people of group AB. But they find that they must give A group blood to A group people
and B group blood to B group people. I have O group blood and the doctor told me that I could give
blood to anyone else safely.
     There is another problem. To give blood of the right kind, doctors have to find a person of the right
blood group. Often they can not 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. At first they find they can keep it in bottles for
fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. 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 become ill. You may need blood. The "blood
bank" will give it to you.1. From the passage, we learn that sometimes people die when they have blood transfusions because they _____.    A. are unhealthy people
    B. have lost a lot of blood
    C. are not given the right kind of blood
    D. are AB group people2. Which of the following is true?    A. Doctors can give any kind of blood to the writer.
    B. The writer can give blood to B group people.
    C. The writer has never had a blood transfusion.
    D. The writer has the same kind of blood as his father.3. People set up the "blood bank" so that they can _____.    A. give the right kind of blood to the people who need it in time.
    B. keep different groups of blood as much as possible.
     C. make it easier to sell or buy blood
     D. keep blood for more than twenty hundred years4. From the last paragraph (段落) of the passage, we learn that _____.    A. the writer thinks it"s good to give blood to a "blood bank"
    B. we may become ill if we give blood to a "blood bank"
    C. many people died because they lost a lot of blood
    D. blood is more important than money5. The writer doesn"t talk about _____ in the passage.    A. how important blood is to us
    B. the four groups of blood
    C. where the blood bank is
    D. what " blood transfusion" is
