     Most American students have to say goodbye to fancy (高档的) fruits these days, In school restaurants across the country, cheaper fruits like apples and oranges have taken their place.

     "People are afraid to spend now," said Linda Morrow, who owns a shoe and handbag store. "They

don't know what the future will bring. "  During the financial crisis  (金融危机), several of the country's

biggest banks have been forced to sell or close. This has made lots of Americans afraid to buy expensive

things.

     The crisis began last year. Experts (专家) think it was because US banks lend money too easily.

Last year a lot of people and companies, who borrowed money, found themselves unable to pay it back.

This left the banks, as well as the people who put their money in the banks, without money. Since the

banks borrowed money between themselves and even across borders (国界) , the whole world was in

trouble.

     This month the US government agreed on a $700 bullions plan to try to save the financial market.

But no one is sure whether it will help or not. Last week presidents from 20countries promised to work

together to find a way out of the money trouble.
