Time is lacking beginning and end, and each person's life is limited, a person's time is limited. If a person's life has come to an end, so he has the time will soon come to an end.
In the universe of 1 000000000 universes, the greatest, the most fair, most selfless time living in the most common and most valuable or time. Spring summer autumn and winter, year after year. Poplar blight, green again when the flowers withered, but there is a time of blooming. However, the life of a person only once. " Flowers are re-opened, no-one juvenile ", time also is such, step by step, section by section, never stop, " the Yellow River water to the sky, back to the sea ", transient.
Therefore, we should cherish and your time. The ancients said, " the night lights even days, is the widespread study. Black do not know as early as hard, white the first study to regret later ", it is telling us : life is limited, must treat time as gold, do not take precious is time wasted, but while youth time to learn more knowledge, in their own the rest of one's life for a big catch. The ancients did so, do we not as good as the ancients?
珍惜時間
時間是無始無終的，而每個人的生命卻是有限的，屬於壹個人的時間也是有限的．如果壹個人的生命走到了盡頭，那麽他所擁有的時間也即將宣告結束。
大千世界中，最偉大、最公正、最無私的是時間生活中最平凡又最珍貴的還是時間。春夏秋冬，年復壹年。楊樹枯了，有再青的時候百花謝了，有再開的時候。然而，壹個人的生命卻只有壹次。“花有重開日，人無再少年”，時間亦是如此，壹步壹步，壹節壹節，永不停留，如若“黃河之水天上來，奔流到海不復回”，稍縱即逝。
因此，我們應珍惜屬與自己的時間。古人說的“三更燈火五更天，正是男兒讀書時。黑發不知勤學早，白首方悔讀書遲”，正是告戒我們：生命有限，必須惜時如金，切莫把寶貴是光陰虛擲，而要趁著青春的大好時光多學點知識，在自己的有生之年裏爭取趕壹反大事業。古人尚且如此，難道我們還不如古人嗎?
