He Called It Penicillin（他命名它为青霉素）
Alexander Fleming was born on a farm in Scotland in the year 1881.When he was thirteen he went to live with his brother, who was a doctor in London.For five years he worked in a shipping office,but he did not stop studying.In 1902,his uncle left him a little money,and that made it possible for Fleming to become a student at the medical school of St Mary's Hospital, a part of London University.
One of the famous doctors who taught the students at Stmary's at that time was Sir Almor Wright,a bacteriologist.He had done a great deal of the most useful research into the work of blood in protecting the body against bacteria.Fleming learnt from him.
During the First World War, Fleming worked as an army doctor in France.He saw large numbers of soldiers die of their wounds because the wounds made it possible for bacteria to work and multiply（繁衍） so quickly that the blood could not deal with them.
After that war Fleming specialised in（专研） bacteriology,and in 1924 he himself became the professor of
bacteriology,and in Hospital.He continued the research for which St Mary's was famous.In particular he was looking for substances which would directly attack harmful bacteria without doing any harm to the body.
In 1928 he was studying the bacteria which caused painful skin disease.In order to find out how to deal with these germs he was growing them on small paltes.One day he noticed a small area of blue-green mould(霉菌) on one of the plates.It would be necessary to grow the bacteria again.He put the mould under his microscope.It was a very common mould.But the microscope showed Fleming something else:the bacteria all round the mould were dead.
(To be continued)
