1 . Look closely at your hands. Are they clean? It doesn’t matter how many times you wash your hands, microbes (微生物) still stay on them. But don’t worry. Most microbes don’t harm (伤害) you.

In a scientific magazine, a scientist, Noah introduces (介绍) the new use of the microbes on our hands: to catch the criminal (罪犯). Everyone has his own microbes on the hands. That is to say, if you and your best friend were able to see all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend’s hands.

When you work on a computer, you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don’t leave your fingerprints behind, your microbes may give you away.

Noah says, “You can only clean a fingerprint, but you can’t do that to the microbes by wiping (擦除) it off.” He says that scientists have a lot more work to do before the microbe is really used to find criminals.
