pictures of the small living things – he called them ―microbes‖ or ―germs‖ (细菌) – that crowded in a drop of water. Because of Pasteur’s patient ways, he was able to make many observations (观察) about germs.

One day a winemaker came into the lab, hoping that someone could help him with his problem. ―Sometimes my wine tastes delicious, but sometimes it turns sour,‖ 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 sour wine had some unusual germs. If he killed these germs, maybe he could keep the wine from turning sour. He experimented with different ways to kill the germs. In the end he found heating 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 sour so quickly. When breweries(啤酒师) heated beer(啤酒), it tasted better. People called the process (过程) ―pasteurization‖ – heating a liquid(液体) to kill bad germs. Aren’t you glad that the milk you drink has been pasteurized?

Looking you in the eye

Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.

The eye-recognition(眼睛识别) programme is already being tested in shops and banks in the USA, Britain, Spain and Italy. Soon, this technology will take the place of all other ways of finding out who people are.

However scientists are working on other systems(系统). Machines will soon be able to
