Take a look at the label(标签) on almost any bottle of milk and you may see the word PASTEURIZED. What does that mean? Let’s find out by meeting Louis Pasteur.

Louis Pasteur was born in 1822 in a little town in France. As he grew up, he loved to paint. He loved to look at the world around him. When he went to college in Paris, he showed interest in looking through a microscope. A microscope makes things look a lot bigger; it lets you see things you can’t see just with your eyes. Looking through a microscope, Pasteur found a living world in a drop of water. He saw and drew pictures of the small living things -- he called them “microbes” or “germs”-- that crowded in a drop of water.

One day a winemaker came into the lab, hoping that someone could help him with his problem. “Sometimes my wine tastes delicious, but sometimes terrible,” he said to Pasteur. “Can you help me find out why?”

Pasteur put some drops of the wine under the microscope. He noticed that the terrible wine had some unusual germs. If he killed these germs, maybe he could keep the wine from turning terrible. He tried with different ways to kill the germs. In the end he found heating (加热) the wine seemed to work best. The winemaker tried it, and every bottle of wine tasted good.

Pasteur’s idea worked for other people, too. When farmers heated milk, it didn’t turn bad so quickly. When breweries heated beer, it tasted better. People called it “pasteurization” ---heating a liquid to kill bad germs. Aren’t you glad that the milk you drink has been pasteurized?

Dear Mary,

Many students around the world have the same problems as you. Here is some advice to help you deal with the street. Good luck!
