【推荐3】Before the discovery of DNA information in the 1980s, fingerprint(指纹) science was the easiest way to solve serious crimes. It’s believed that each one of us has our own fingerprints. But did you know that our fingerprints could show a lot about us?
According to the expert, fingerprints can show lifestyle and environment, eating habits, possible medical problems and even the job of a person.
So how can we work all this out from just a simple fingerprint?
Well, a fingerprint is formed when a finger touches a surface. Most fingerprints can’t be seen to the eye and require a chemical development process in order to make them shown.
Besides, its use could be much wider. For example, it may be helpful in the future to doctors treating their patients. A fingerprint exam may also tell a doctor whether a patient is properly taking medicine. In the treatment of some of the most serious illnesses, taking proper medicine is important.
In the future, finger print science can be used by the police and help doctors keep us in the best possible health.

【推荐1】Every week, Brad’s parents gave him some pocket money. They didn’t give him the money as a gift, though. Brad actually earned it. Each day, Brad took out the trash and cleared the table after dinner. He fed the family dog and took him for walks. For all of this work, Brad earned $12 each week. The problem was, the money Brad earned seemed to be spent out just as quickly as he earned it. His dad said that money seemed to “burn a hole in his pocket”. Brad spent his money on video games more than anything else. He never seemed to have enough money.
Dad suggested Brad creating a budget (预算) to set aside money each week for certain expenses. “You spend only as much as your budget allows. That way, you are sure to have money for the different things you want.”
That night, the family made a list of the different types of things that Brad would be able to spend money on. The list included the type such as food, clothing, and entertainment. And they said a budget should also set aside a percentage of earnings as savings so that he would be able to buy something expensive in the future. “It can also be your rainy day fund,” said his mom. Brad gave her a puzzled look. “A rainy day fund is there to help out in an emergency (紧急情况),” she explained. And at last they said it was also important to set aside a little money to help others.
From that day on, Brad always seemed to have enough money to do the things he wanted. The first year, he set aside $104, and he chose to give the money to the town’s animal shelter. Giving money to help those in need made Brad feel good. He also used some of his savings to buy a cool new video game console. That made him feel good, too.

C.By doing some housework. | D.By making a good budget. |
A.Be difficult to earn. | B.Disappear (消失) quickly. |
