Where you save your money often depends on what you are saving for. If youare saving to buy a book or to go to a concert, then you would probably keepyour money somewhere in your room. If you are saving for a big purchase like awashing machine or a car, where would you save your money?One place to save money is the bank. If you put your money in a piggy bank (猪形蓄罐),one year later you'll still have the same amount of money as you putin. If you put your money in a savings account, one year later you'll have moremoney than you put in. Why?When you keep your money in a bank, your money earns interest. Interestis an amount of money a bank pays you to use your money. The bank usesyour money (and the money of other people, too) to lend to its customers andbusinesses. It will send you a statement several times a year. A bank statement tellsyou how much money you have in your account and how much interest you haveearned. If you leave your money in the bank, you can watch it grow!Another way you can save money is to get a certificate of deposit (CD). If youhave some money that you don't need to use for a long time, this is a good wayto make your money grow. You can get a CD at a bank. You agree not to use themoney for a certain period of time. That period might be from six months to fiveyears. You can't touch your money during that time. If you do, you must pay a penalty (罚款),or fee.
