     Imagine there is a bank that opens an account (账户 ) for you each morning with $86,400. Every evening

the bank deletes (删除) all the money that remains (剩下,余留).

      Each of us has such a bank. Its name is Time. Every morning, it gives you 86,400 seconds. Every night

your unused seconds disappear.

     If you fail to use the time in your account, the loss is yours. There is no going back. So what will you do

with the account of your time?

      Take out every second, of course! The clock is running. Make the most of today.

      To realize the value of ONE YEAR, ask a student who failed a grade.

      To realize the value of ONE WEEK, ask the editor of a weekly newspaper.

      To realize the value of ONE HOUR, ask the lovers who are waiting to meet.

      To realize the value of ONE MINUTE, ask a person who missed the train.

      To realize the value of ONE SECOND, ask a person who just avoided (避免,消除) an accident.

      Treasure (珍爱,珍惜) every moment that you have! And treasure it more because you shared it with

someone special. Remember, time and tide wait for no man.
