参考：Students under the flag speech - cherish today someone say: people's life has three days: yesterday, today and tomorrow, and the three components of the life trilogy. But I said, by the life of people today is composed of numerous will cherish today, because of the people, neither yesterday, nor for meditating tomorrow. Optimistic person, like the description of the future, The pessimist, always worried about what will happen tomorrow. But life connotation is only today, life is precious, it is by a second time accumulation, cherish today is to cherish life, waste today is wasted life.
Yesterday is only, can't stay. If you yesterday, made a little proud achievement exclusiveness, or because the wrong doing a thing, then you will never frown sank into the mire yesterday. At the same time, today you can from your smug or slip away in the frown. Everyone will take "today" this bus to a post, tomorrow, one day a scenery, while tomorrow, we should seize today, so you will be waiting with fruit is tomorrow.
We should not seek what yesterday, also should not to ask what tomorrow, the most important is how to treat today. In the limited time to study hard, to today's every minute, with today's efforts to compensate the gap, to realize yesterday and tomorrow's lofty ideal.
We ended up again after examination, although the large, but haven't announced results in students face, or laughter or sorrow, have already shown without involuntary discharge of urine. However, the examination has ended, and has become the history, became the things I cannot change, may be thwarted, may fail, but not always, "how can we see the rainbow." Failure is not fearful, the defeat. The sailor told our voyage "rain this pain, wipe tears, don't ask, at least we have dreams." Our youth is warm, our goal is to clear
Clever people, check yesterday, today, tomorrow to plan, Foolish man, yesterday, today, dejection dream tomorrow. A valuable life should be: take yesterday, today, the surplus plentiful full of hope tomorrow.
Students, let's cherish today, cherish every minute!
翻译：中学生国旗下演讲稿--珍惜今天 有人说：人的一生有三天：昨天、今天和明天，这三天组成了人生的三步曲。但我说，人的一生只是由无数的今天构成的，因为不会珍惜今天的人，既不会感怀昨天，也不会憧憬明天。 乐观的人，喜欢描述明的美好前景；悲观的人，总担心明天会发生什么不测。但生命的内涵只在于今天，生命是宝贵的，它是由一分一秒的时间堆积而成的，珍惜今天就是珍惜生命，荒废了今天就是荒废了生命。
昨天已是过眼云烟，再也无法挽留。如果在昨天，你为取得了一点骄人的成绩而沾沾自喜，或是因为做错了一件事情而愁眉不展，那么你就永远陷进了昨天的泥潭里。同时，你今天的时间也会从你的沾沾自喜或愁眉不展中悄悄流逝。每个人都会乘坐“今天”这班车驶向明天，一天一个驿站，一天一处风景，趁着明天还未到来，我们就应抓住今天，这样等待着你的才会是果实累累的明天。
我们不应该在昨天寻觅什么，也不应该向明天祈求什么，最重要的是怎样对待今天。在这有限的时间里努力学习，抓紧今天的分分秒秒，用今天的努力去弥补昨天的空隙，去实现明天的崇高理想。
我们结束了一次又一次的大型的考试之后，虽然结果还未揭晓，但在同学们的脸上，或喜或忧，早已展露无遗。但是，考试已经结束，已经成为历史，成为了不能改变的事情，也许会受挫，也许会失败，但是，“不经历风雨怎么见彩虹。”失败并不可怕，可怕的是认输。远航的水手告诉我们“风雨中，这点痛算什么，擦干泪，不要问，至少我们还有梦。”我们的青春是炽烈的，我们的目标是明确的
聪明的人，检查昨天，抓紧今天，规划明天；愚蠢的人，悲叹昨天，挥霍今天，梦幻明天。一个有价值的人生应该是：无怨无悔的昨天，丰硕盈实的今天，充满希望的明天。
同学们，让我们共同珍惜今天，珍惜现在的分分秒秒吧！
