古往今来，“时间”对人来说是个最难捉摸的东西。世上每人每天都有着等量的时间——24小时。并且大家 也都一样，只能占有“今天”。一点不假，昨日之日不可留，一去不复返了。而明天，也许要使人们期待着 永远也盼不来。这就是说，每个活着的人就只能掌握“今天”——只能掌握此时此刻。
Time is one of the greatest riddles of the age. Everyone in the world has the same amount of it—24hours each day. We are all alike, too, in only having today. Yes, yesterday is gone, tomorrow may never come—so every living person has today, this hour, this minute at his disposal.
