　　Nine-year-old Louis Pasteur rushed into the little house his face white.

　　“Mother!”he cried.“A mad dog has bitten my friend Henry and now they are burning him with redhot irons. It’s terrible!”

　　“Rabies(狂犬病) Louis. Burning the bites(伤口)is the only hope of stopping Henry from catching the disease.”

　　Henry did get rabies and died in great pain some days later. Louis Pasteur never forgot.“One day ” he thought “I must do something to help people like Henry.”

Sixteen years later Pasteur became a Doctor of Science. And he began making important discoveries in his special field.

　　Pasteur achieved great success in his life. But during the years of research he lost the use of his left arm and leg. Yet he worked on and on as hard as ever as he was eager to find a way for curing rabies. He never forgot his friend Henry.

　　After many dangerous experiments on mad dogs he finally found the answer. Just then a boy who had been badly bitten by a mad dog arrived at his lab. A few days after Pasteur’s treatment the boy got better. He did not catch rabies.

　　The discovery gave a new hope to people in many countries. People sent money to help build the Pasteur Institute in Paris. Today it is one of the world’s most famous centres for research.
