Well, obviously its because we have mirror neurons (神经元) in our brains.Put simply, the presence of mirror neurons suggests that every time we see someone else do something, our brains model after it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions，they also tell us that there is a biological basis for the way we understand other people.Mirror neurons can undoubtedly be found all over our brains，but especially in the areas which relate to our ability to use languages，and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: “The hand took hold of the ball”), the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball). Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning (行使职责). However, it is not yet known exactly how these discoveries might help find treatments for social disorders.Research into mirror neurons seems to provide us with ever more information about how humans behave, communicate and spend time together. Indeed, it may turn out to be nearly the same important thing for neuroscience as what Einsteins theory of relativity (相对论) was for physics. And the next time you have the strong feeling to cough in the cinema when someone else does well, perhaps youll understand why.48.

The purpose is to let children learn from experiences at an age when financial (财务的) mistakes are not very costly.How much money that parents give to their children to spend as they wish is quite different from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.In any case, parents should make clear what, if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget (预算). Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget requires a choice between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics.Many people who have written on the subject of allowances say it is not a good idea to pay your children for work around the home. These jobs are a normal part of family life. Paying children to do other work around the house, however, can be useful. It can even provide an understanding of how a business works. Allowances give children a chance to experience the three things they do with money. They can share it in the form of gifts or giving a good cause. They can spend it by buying things they want. Or they can save it.Saving helps children understand that costly goals sometimes need to give up something. You have to cut costs and plan for the future. Requiring children to save part of their allowances can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A saving account (账户) is an excellent way to learn about the power of compound interest (复利息).Compounding works by paying interest. So, for example, one dollar invested at two percent interest for two years will get two percent of one dollar and two cents, and so on. That may not seem like a lot, but over time it adds up.52.
