Passage1（课内同源：巴斯德与巴氏消毒法）

　　In today's English class, Ms Liu tells the class a story about milk. Long ago, people did not know how to keep milk fresh for long. Many children became ill after they drank it. “A French scientist found the answer,” Ms Liu says. “His name was Louis Pasteur.”

　　Pasteur found small living things in milk. These germs made people ill. He heated the milk and then cooled it quickly. Most of the germs were killed in this way, and the milk stayed fresh for longer. This way of cleaning food was named after him, and today people call it pasteurization.
