His research showed that tiny germs spread diseases, and the spread of the germs could be controlled. With this knowledge, humans were able to save many lives. Pasteur discovered a way to make milk, wine and food safe. The method, known as pasteurization(巴氏杀菌), was named after him. One day, a winemaker had bad-tasting wine and asked Pasteur for help. Pasteur found that the bad-tasting wine had some unusual germs. If he killed these germs, maybe he could keep the wine from turning terrible. After trying different ways to kill the germs, he found heating the wine seemed to work best. Later, Pasteur found out that by heating these foods and freeing them from harmful germs, they could be better kept. The heat kills the germs that spread diseases. Pasteur also helped greatly in medicine. In the summer of 1885, 9-year-old Joseph was attacked by a sick dog with rabies（狂犬病）. There was no medicine for rabies at that time. Luckily, Pasteur was studying about the germs that cause rabies. He believed that he had a medical method for rabies, but he never gave it to a person before. However, the doctor said the child was dying, so Pasteur gave Joseph daily medical help for ten days. Slowly, the child became better. This opened the way for the development of vaccinations（疫苗）. Vaccinations keep humans from contracting certain illnesses and help them stay away from many diseases. During Pasteur’s life, he touched on many problems. A simple description of his achievement doesn’t show how excellent he was. What Pasteur achieved(达到) for the scientific world makes him one of the most important scientists of all time. ( )1.
