When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become 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 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（输血）". 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 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 may become ill. You may need blood. The "blood bank" will give it to you.

Does eating a good breakfast improve school study? More than 1,000 students in the city of Lawrence took part in an experiment (试验) a year ago, and the answer is YES. In the experiment, students with breakfast got high scores in their tests than those without breakfast. Among those with breakfast, fewer were late for school and much fewer missed their school. “By eating breakfast, you feel active in your morning study and keep good health,” says Amy Sampson, a famous doctor. He did the experiment for a year.

Making mistakes
It’s good to make mistakes．And here’s why．
First of a11．mistakes are a clear sign that you are trying new things．It’s always good to try new things because when you’re trying new things you are growing．If you never try anything new,how can you improve and develop?The simple answer is,“You can’t.”
Another good thing about mistakes is this：When you are making mistakes，you are learning．Consider this：Edison failed 1 0,000 times— before he perfected the light bulb．When he was asked how it felt to fail that many times，he replied that he hadn’t failed 1 0,000 times，but rather had learned 10,000 things that didn’t work．
Finally,when you make a mistake，you are much closer to success．Why?Because every time you make a mistake，you are one step closer to success．But it doesn’t mean that you can make mistakes without thinking．Instead，when you try something new,you have to think it over，so that you can keep away from some unnecessary mistakes．
There is an old saying that goes．“If you are not making mistakes．you are not trying hard enough.’’ So go forward and make mistakes．And learn．And grow．And succeed．
【小题1】According to the passage，when you are making a mistake，that means             ．
