To realize the value of one month：Ask a mother who has given birth to a premature baby.To realize the value of one week：Ask an editor of a weekly newspaper.To realize the value of one hour：Ask the lovers who are waiting
2、 to meet.To realize the value of one minute：Ask a person who has missed the train， bus or plane.To realize the value of one second：Ask a person who has survived an accident. To realize the value of one millisecond：Ask the person who has won a silver medal in the Olympics.Time waits for no one.Treasure every moment you have.要想知道一年的价值，那就去问期末考试不及格的学生。要想知道一个月的价值，那就去问生了早产儿的母亲。要想知道一周的价值，那就去问周报的编辑。要想知道一小时的价值，那就去问等待见面的恋人。要想知道一分钟的价值，那就去问误了火车、汽车或者飞机的人。要想知道一秒钟的价值，那就去问大难不死的人。要想知道一毫秒的价值，那就去问奥运会获得银牌的人。时间不等人，你拥有的每一刻都要珍惜。
