参考答案：B
| Many people have two accounts in a bank, A savings account and a checking account. When people deposit money in a savings account, it earns interest. They can withdraw their savings at any time, unless it is a special notice account. A special notice account earns higher interest, but you must give the bank 90 days notice before withdrawing money from it. People use checking accounts for convenience. They deposit some money and write checks when they want to pay bills. This way they do not have to send cash through the mail. They do not have to carry a lot of cash with them, for they can write a check instead. At the end of the month, the bank returns the checks they have written and have been cashed. The bank also sends a statement of all the checks used. That way people have a record of how much money they have spent that month. |
People using savings accounts can withdraw their savings whenever they like.
