If you ask me what is the most precious, I would say that it’s time. Time is something once lost, you could never have again. Therefore, we should cherish it and spend it in meaningful things. However, many people do too many meaningless things to kill their time, such as playing computer, watching TV, or gossiping. When you do these things, the time has long been unwittingly flowed away. In my opinion, the best way to make full use of time is planning your time rationally and sticking the plan firmly. Spending more time on something significant not only will make your life fulfilling, but also will give you a sense of accomplishment. Instead, killing your time with meaningless things would bring you depression even despair. Remember that those who abandon time will be also abandoned by time.
时光永是流逝，不知不觉我们已身处最令人羡慕的年龄——17-18岁，正是我们将青春的光芒，毫无保留地，充满活力的释放出来的，人生中最黄金的年龄。因为这时正是由少年变为青年，由孩子变成大人的临界点，我们有着比孩子们多一点的成熟与思想，又有着成年人多一点的童稚和调皮，有如此的性格优势，我们难道不该珍惜青春，珍惜这似水般流走的日子吗？
但有些同学却不懂得珍惜青春，他们成天把“好累啊，我不想活了”挂在嘴边，成天对天感叹“时间怎么过得这么慢啊！”
现如今，校园里的打架斗殴，自杀事件已屡见不鲜，足以见出同学们是多么轻视生命。
当“一天要二十四个小时做什么啊，十二个小时就够了，八个小时睡觉，四个小时吃饭，这不是很好吗？”之类的话在校园里传开并被奉为经典时，是不是可以说明学生的时间观出现了很大的问题？
难道你不觉得这是很可怕的事情吗？处在黄金年代的年龄，本应活力四射的我们居然觉得生命无趣，时间太长。
“浪费时间等于谋财害命”。千千万万的人因虚度年华而最终悔恨，到头来只能“白了少年头，空悲切。”现在的我们却还未体会到这些，待到体会到时，已经晚了，逝去的时光再也不会回返。为了不致将来后悔，现在请珍惜时间吧！
珍惜时间就是珍惜生命，青春在生命中有那么几年，却只有一次，丢掉了就不会再拥有。
时光永是流逝，我觉得不管我们想什么，做什么，都应该对得起眼前如花似锦的青春，都不该浪费每分每秒不分昼夜喧哗流过的时间。让我们珍惜青春，共同期待：明天会更好！
燕子去了，有再来的时候；花儿谢了，有再开的时候；树木枯了，有再青的时候；可时间却如滚滚长江东逝水，奔流到海不复回。时间是何等重要，所以我们要珍惜时间。
时间是人类的财富，是全部财富，正如时间是国家的财富一样，因为任何财富都是时间和行动化合的结果……居里夫人说过：“我只惋惜一件事，日子太短，过得太快。一个人从来看不出做了什么，只能看出来该做什么。”倘若给居里夫人更多的时间，她会创造出世上更灿烂的辉煌，为人类创造出更多的财富。
时间就是生命，珍惜时间就是爱护自己的生命，因为时间是组成生命的材料，生命是以时间为单位的，放弃时间的人，时间也会放弃他。记得二次世界大战期间，发生了时间与生命有关的一件事。在美国与德国交战时，美国要派100名战士到德国后方，他们要学会德语，限他们40天学会，学会的人去，学不会的人也是要去的。如果学不会，德国人就会发现他们是 “美国鬼子”，那岂不是白白送死？所以，40天之内，100人都学会了德语。
时间是乌黑秀发中的几根白发，是生日蛋糕上逐渐增多的蜡烛，是无法挽留却又一次次重复的春秋与冬夏。时间催促沧桑的巨变，时间扬起未来的风帆，时间是生命的黄金海岸，时间是获取成功的基石，时间是人类的生命航船。
珍惜时间吧！莫等闲，白了少年头，空悲切！
Good morning, everybody!
In this world, there is one thing that is very fair to everybody, whether you are a male or female, young or old, rich or poor. Does anybody know what it is called?
Right. It is time. The topic I am going to present to you today is called “ Treasure Every Minute”.
To realize the value of ONE YEAR, ask a student who failed a grade.
To realize the value of ONE MONTH, ask a mother who gave birth to a premature baby.
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 an accident.
To realize the value of ONE MILLISECOND, ask the person who won a silver medal in the Olympics.
Treasure every moment that you have! And treasure it more because you shared it with someone special, special enough to spend your time with.
And remember that time waits for no one. Yesterday is history. Tomorrow is a mystery. Today is a gift. That's why it's called the present!! The clock is running. Make the most of today.
Good luck, everybody!

中文
时间就是生命，鲁迅先生说：“浪费自己的时间等于慢性自杀，浪费别人的时间等于谋财害命。”这就说明了珍惜时间的重要性。
时间对于学者来讲：“一寸光阴一寸金，寸金难买寸光阴。”学者只有珍惜时间才能创造自己的价值，为人类的文明发展，开拓新的知识天地。科技才能进一步发展，为祖国腾飞奉献自己的才华。反之，不珍惜时间，碌碌无为的过日子，明日复明日，不但毁了自己的前程，还给国家带来经济上的损失。
时间对于军事学家来讲，珍惜时间就是胜利。红军要飞渡金沙江，夜以继日地行军，其目的就是争取时间，夺取胜利。可见珍惜时间是多么重要，这关系着祖国的生死存亡。
时间对于经济学者就是金钱，就是效率。随着改革开放的大潮，时间越来越被人们重视，往日工作散怠，做一天和尚撞一天钟，吃大锅饭的现象越来越少，呈现在眼前的是抓紧时间创造效益，创造财富。
珍惜时间就是珍惜生命，生命对于每个人都很重要，我们每个人都应好好地珍惜时间，创造自己的生命价值。
