    In the current economic downturn, many American schools are adding a new

Subject: financial literacy (理财). One program in Virginia even gets students out of

the classroom for a day to learn how far their money will go in the real world.  What

looks like a shopping mall is actually an educational field trip experience for a group of

young people.

    Finance Park is a special place where students apply what they have been taught in

class about money management.  The facility (设施) opened last year in Fairfax,

Virginia.  It is the fifteenth Finance Park built in the last decade by Junior Achievement

USA, a non-profit organization helping to prepare young people for financial success.

"Since the financial crisis (危机), the demand for Finance Parks around the country

has grown," says Ed Grenier, president of the Washington, DC chapter.

    Financial literacy has only recently become part of the regular subjects in Fairfax

County. "Some students, some teachers, some schools did it, but now it is much

more systematic," Reilly says, "and it can ensure that all students get this background

information." That is why every eighth grade student in Fairfax County will eventually

spend a day here.

    Thirteen-year-old Sam says she has learned an important life lesson. "I didn't know

how expensive everything would be." Anthony, also 13,is looking forward to telling

his parents what he learned."I'11 probably tell them I want to stay a kid a little longer

and take my time to become an adult." This isn't the end of financial studies for

Anthony and the other students here.  Virginia is one of 23 states which requires

students to take a financial education class in high school in order to graduate.
