    Saving Money

    Where 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'II 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.
    You can buy a CD at a bank.You agree not to use the money for a certain period of
    time.That period might be from six months to five years.You can't touch your money
    during that time.If you do,you must pay a penalty,or fee.

    The word"touch"in paragraph 7 could be best replaced by
    A:deposit.
    B:lend.
    C:use.
    D:cash.

    答案:C

    during that time.If you do,you must pay a penalty,or fee.
    Since the bank is using your money for that time period,it will pay you interest.You
    will earn more interest with a CD than in a savings account.Can you guess why?It's
    because you promise to leave your money in the bank for a certain period of time.Banks
    pay different rates of interest.So,you may want to compare rates in newspaper ads before
    buying a CD.

    The word"touch" in paragraph 7 could be best replaced by
    A:"deposit".
    B:"work".
    C:"use".
