科目： 來(lái)源：2010-2011學(xué)年度濟(jì)寧市鄒城縣九年級(jí)模擬考試 題型：

Many hospitals have blood banks．In these banks, blood of all types is stored．When blood is needed, it is taken from the bank．Healthy people then give blood to the bank to replace (取代) the blood that is used．Blood can be kept in the fridge for about three weeks with a kind of chemical．

When people lose much of their blood because of operation or accident, they may need transfusions (輸血)．Some people may need transfusions because of illness．Sometimes only a part of the blood is used for transfusions．Plasma (血漿), the liquid part of the blood, may be given alone．Transfusions of plasma are often given when people have been badly burned．

When a person gets a transfusion, he gets blood of the same type as his．Or there maybe a bad reaction (反應(yīng))．To make it safer, before a transfusion is given, the blood to be used must be tested with the blood of the person who is to receive it．This testing is called cross matching of the blood．

Oswald Robertson, an American doctor, was the first one to give transfusions．He used blood that had been stored for some time to help wounded soldiers in 1918 in World War I．
