But there are two problems. First, it does not always work. Sometimes people die when they ( 2 ) 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 ( 3 ) give A-group blood to A-group people and B-group blood to B-group people. If a person has O-group blood and the doctor could give his 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 cannot find a person in time. At first they find they can keep the blood in bottles for fifteen to twenty days. They do this by ( 4 ) it very cold. They find how to keep it longer in the end.
One day, when you grow up, you may decide to give blood to a “blood bank”. In this way, you may stop ( 5 ) dying. Or perhaps one day you may become ill and need some blood with the same kind.

解析
血液十分重要,这一点人们是一直知道的。有一段时期,一些人甚至为了强壮而喝血。当医生了解血液是如何在人体中运行时,他们用各种办法给需要的人输血。 他们把血液从一个人身上移到另一个需要的人体内。这叫做”输血”。血液从健康人的手臂流淌到病人的手臂。 但有两个问题,首先,输血不一定成功。有些人输血后就死了。后来,医生发现认得血液是不同的。有四种——O,A,B 和 AB 型。我们都拥有四种中的一种血型。他们还发现任何血都 可以输给 AB 型血的人。但他们发现,A 型必须输 A 型,B 型必须输 B 型。我是 O 型血所以医 生告诉我我的血可以安全地输给任何血型的人。还有一个问题。为了输对血,医生必须查出这个人的正确血型。有时不能及时找到输血 者。如果他们能把血液保存至需要的时候,那就能保证有能配对的血型了。刚开始,他们发现他 们能把血液保存进瓶子里长达 15 至 20 天。那是在冷冻的情况下。接着他们研究出能保存更长久 的办法。最后,找到了能保存很久很久的办法。我们把存钱的地方叫做“银行”。把存血液的地方叫做“血库”。有一天,当你长大了, 你会决定给血库捐血。这样,你就可以挽救一个人的生命。或者也许有一天你生病了,你可能需 要输血治疗。血库就会给你提供血液。
