　　Allowances give children a chance to experience the three things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save it.

　　Saving helps children understand that costly goals require sacrifice. You have to cut costs and plan for the future. Requiting (酬劳) 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.

　　Ⅲ.阅读简答(10 min.) California called Trans Time. Trans Time freezes people after they die. Why does Trans Time freeze people? Doctors today can cure many diseases, but they cannot cure all diseases. People still get sick and die. Maybe in the future doctors will have medicine for all diseases. Some people think so. They want Trans Time to freeze their bodies after they die. Maybe 100 or 200, or 300 years later, Trans Time doctors will bring the people back to life. The doctors will cure their diseases, and the people will be alive and healthy again.

　　People often ask the scientists at the Trans Time, “How will Trans Time bring dead people back to life？” They say, hen they say “someday”， they mean years from now — maybe 100 or 200 years. How can Trans Time keep people frozen for 200 years?

　　After a person dies, workers at Trans Time cool the body with ice and chemicals. When the body is very cold, workers put the body into a capsule (密封舱). They fill the capsule with liquid nitrogen (液氮). The temperature in it is 196 degrees centigrade below zero. Every two weeks workers add more liquid nitrogen. The liquid nitrogen keeps the bodies frozen.ans Time charges $21，000 to freeze a body and $59，000 to keep a body frozen. That's $80，000 all together. It is a lot of money. But some people think that $80，000 is a fair price. It's a fair price for a chance to live again, isn't it?
