1.Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you.     Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to indentify the criminal.      Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare 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 Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使无菌) a surface just by wiping it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.

4.This Thursday, across the US, kids are skipping school and going to work with their parents. They’ll be making copies, sending faxes(传真)and sweeping floors. This is because April 28 is Take Our Sons and Daughters to Work Day all over the US. This holiday shows kids what it means to be a grown-up in the working world.I still remember when this day started, I was very happy. Not only did I have the chance to miss school, but I also got to sit in my dad’s taxi all day long and we would go to a restaurant for lunch.But after only 20 minutes of driving around the city. I was very bored. I couldn’t read my book in the car as I would get carsick and my dad didn’t like to turn on the radio. I got hot and uncomfortable. people wouldn’t get into his taxi because they thought he already had a passenger: me―so nothing happened. It seemed years before we went out for lunch. I actually started to miss school.While the point of the day is to give kids a chance to experience real-life jobs and give them an idea of the possibilities for their futures, I got something completely different from the day. I learned to appreciate(重视) school. Where else do you get to play with your friends, do science experiments, read great books and write stories all in one day?Just as you’ll have to learn to love your job later in life, learn to love school now. If you don’t already, try spending the day at work with your dad.
