根据下列文章,请回答题。Saving MoneyWhere you save your money often depends on what you are saving for. If you are saving to buy a CD．(光盘) or to go to a concert, then probably you would keep your money somewhere in your room.If you are saving for a big purchase like a mountain bike or a school trip, where would "you save your money?
One place to save money is the bank. Putting your money in a savings account will help your money earn more money. If you put your money in a piggy bank (猪形储蓄罐), one year later you'll still have the same amount of money you put in. if you put your money in a savings account, one year later, you'll have more money than you put in. Why?
When you keep your money in a bank, your money earns interest. Interest is an amount of money a bank pays you to use your money. The bank uses your money (and the money of other people, too) to loan money to people and businesses.
The bank will send you a statement several times a year. A bank statement tells you how much money you have in your account. It also tells you how much interest you have earned. If you leave your money in the bank, you can watch it grow!
Another way you can save money is to buy a certificate of deposit or CD. If you have some money that you don't need to use for a long time, this is a good way to make your money grow.
