Look closely at ,your hands-are they clean? It doesn't matter how many times you was  your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive.
Now,  scientists say the microbes that live on our hands could be used in a surprising way: fighting crime.
When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal.  But according to a recent study, investigators could even use microbes to help break a criminal case.
Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint.
The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find.  And policemen use forensics such as studying fingerprints to identify the criminal.
"Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists.
"You can't sterilize(为……杀菌) a surface just by wiping it off. "
His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards.
But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful. 
Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool.

For many people – especially those juggling (兼顾) family and work at the same time --- it can be difficult to stick with a college degree. Kathy Bitzthum thought many times about dropping out of her accounting program at Iowa State University: She had two children and a job at Electronic Technology Corp. She’d only enrolled in the first place because her boss would offer her a promotion if she took a few accounting courses.
Because she only had enough time to take one class at a time, it took her seven years to complete the courses her boss asked her to take on. She received the promotion as her boss promised and wasn’t planning to continue a degree. But a request from her father, who was dying of cancer, made her think twice. He said to her, “Kathy, why don’t you just keep going and get your degree?”
Before he passed away, he made her promise that she would finish it. And he made her a promise in turn. Vitzthum’s parents had agreed to give each of their children a valuable gift when they graduated from college, and Vitzthum was obsessed with an antique she’d come across and knew that she couldn’t afford. After she promised to graduate from college, her parents bought her the antique. Her father told her, “I’m not going to be around when you graduate, so I’ll give this to you now. But it doesn’t _________ until you graduate from college.”
Since then, Vitzthum has looked at that antique every day and remembered the promise she had made to her father. Despite a hectic life as a wife, mother and full-time employee, she’s taken one course every semester for the last 19 years. And finally, at the age of 48, she graduated with a bachelor’s degree in accounting --- and she was excited to accept full ownership (所有权) of the antique that she’d borrowed for more than a decade.

Hilary Smith belonged to a good family. But by the age of twenty, he had spent all the money the good old family had. He then had some trouble with the bank and was put in prison. He escaped from the prison and ran to Australia without delay.

Hilary did not like Australia and Australia did not like Hilary. What he could do seemed to be one of two things: die or work. The thought of neither of these gave him any pleasure. Then he remembered that he was not alone in the world. He possessed an aunt.

She was his father’s only sister, but his father used to say she brought no glory to the family. Hilary, of course, tried to discover what she had done. It seemed that she had failed to marry a nobleman. Instead, she had chosen a husband who was connected with trade. Of course as soon as she became “Mrs Parks”, her brother considered her dead. Later on, Mr. Parks died and left her a lot of money; but that did not bring her back to life in her brother’s opinion.

Hilary discovered his aunt’s address. Fortunately she remained faithful and honest to him even after she fell ill. So Hilary’s star shone again. When he was feeling honest, he could talk attractively. He frequently visited his aunt’s house; and soon he was living comfortably in the building which the profits of trade had provided.

One thing was soon clear: his aunt was seriously ill, and nothing could cure her illness. Hilary was very worried. Fate had found a home for him, and was now going to throw him out of it. There was only one thing that could save him: her will.

“Will?” she said, “yes, I have made one. That was when I was a girl and had not much money. I left all my money to some religious people.”

“Didn’t you make another will when you were married?” Hilary asked.

His aunt shook her head. “No,” she said in a low voice, “There was no need. When I finally had a lot of money I found I had no relations.”

On the next day he went to the public library and examined a book of law. It told him what he already believed. When a woman is married, an earlier will loses its value. A new will must be made. If no new will is made, the money goes to the nearest relation. Hilary knew that he was his aunt’s only relation. His future was safe.

After a few months had passed, Hilary’s problems became serious. He badly needed money. He had expensive tastes, and owed a lot of money to shopkeepers. They trusted him because his aunt was rich; but the debt was terrible.

Unfortunately his aunt did not want to discuss money matters at all. In the end they had a quarrel about the small amount of ten pounds. Hilary was now very angry. He began to wonder about a new problem. Was it kind to want his aunt to live any longer? Was it not better for her to die now? While he was considering what to do, his aunt told him that she was going to send for her lawyer. So she was going to make a new will. Hilary thought she might leave all her money to someone else. Soon he reached a clear decision.He must do a great kindness to the poor old woman.

One night when the old servant who had been nursing his aunt went off, he doubled the amount of some medicine. The total amount was too great and it could just put her to sleep forever.

“Thank you,” his aunt took the glass from his hand with a grateful look. “I want, more than anything, to sleep, and never to wake up again. Is that what you wish, Hilary? I have given you your chance. Don’t blame me if I have some doubts about what you intended to do. Sick people get these ideas, you know. One thing I ought to explain to you. Mr. Parks never married me. He already had a wife and couldn’t marry again. That made your foolish father very angry with me… Well, if I am alive tomorrow I shall make another will in your favor. If I die tonight, you’ll get nothing… No, Hilary, don’t try to take the glass away. If you do that, I shall know; and I don’t want to know. Good night, Hilary.”

Then, very carefully, she raised the glass to her mouth and drank.
