高中珍惜时间作文800字【一】
世界上最快而又最慢，最长而又最短，最平凡而又最真贵，最易被忽视而又最令人后悔的就是时间。今天，我读了《珍惜时间》这篇课文后，心情久久不能平静，文章中鲁迅先生珍惜时间学习，把毕生的精力献给革命的精神深深地打动了我的心。
鲁迅到了晚年，对于时间抓得更紧。不管斗争多么紧张，环境多么恶劣，身体多么不好，他仍是争分夺秒，如饥似渴地学习，夜以继日地忘我工作。病重得时候，他就想病好了要做什么事，病稍微好一点，他就动手做起来。他在逝世的前不久，生着病，体温很高，体重已经减轻到不足八十斤，可他仍然紧张地写作和翻译文章。甚至在逝世的前三天，还给别人翻译的一本苏联小说集写了一篇序言，在逝世得前一天还记了日记，鲁迅一直战斗到他离开我们的那天，从来没有浪费过一点儿时间。
和鲁迅先生一比，我就差了十万八千里。鲁迅先生对时间是那么珍惜，而我却不懂得珍惜时间，任凭宝贵的时间白白在眼前流逝。比如在双休日里，我知道早晨不用起早，所以都是太阳出得老高才懒洋洋地起床，就是起来了也不想写作业，心想时间还早着呢，于是就出去玩了。因此，每个双休日我都是星期天下午才匆匆忙忙地赶作业，完成的质量可想而知了。
每次吃饭的时候，妈妈总说我耽误时间，因为我总是一边吃一边看电视，一点一点地吃，吃一顿饭，就要耽误一个多小时。现在想想，如果把节约的时间用来看书，还能学到许多知识呢。
古人言：“勿谓今日不学有来日，勿谓今年不学有来年。”学了这篇文章后，我一定要像珍惜自己的生命一样地珍惜时间。

For thousands of years， animals have trodden a slow path， their spirits together with the body。 But our human being\'s transportation is too fast。 The body moves but the soul is left behind。 We try to free ourselves in convenience， but we only imprison the soul。 Since we invented how to count hours， we do everything to short the time， short the deadline。 But the time saved can\'t be shorten。 Nowadays， we spend lots of time staying in front of a TV just changing the channels， while we have no time to talk with a good friend or play with our family。 We have plenty of time to search old news on the internet， while we hardly think about our life。 In the end， the only thing apparent is our loneliness。
Take your time， please。 Try to follow the natural steps and have your own clock。 Try to share your time with everybody you love， share your mind， your happiness and sadness。 Try to read the world we live in， do not only catch a quick glimpse at the society。
Someday， when we know how to spend every second in our life， we can then live our own life。

高中珍惜时间作文800字【四】
“明日复明日，明日何其多，我生待明日，万事成蹉跎”这是《明日歌》仅仅这短短的几句话，给了我深刻的印象。现在生活的条件优越起来，我们就应该珍惜时间，珍惜这每一分，每一秒。
“今天，不就是短短的一天吗，我明天再学习不可以吗?”我也有过这样的想法，也曾经这么做过。当我读过《明日歌》时，我才发现我错了，为什么要把今天可以完成的事情放到明天呢?很快，到了明天，还有明天，明天就变成了今天，而每个今天之后，又有无穷无尽的明天，大好的光阴、就被浪费了，到了以后，就会有了“少壮不努力，老大徒伤悲”的叹息。
勤奋，有志的人，深深懂得时间就是生命，甚至比生命还宝贵。他们从不把今天可以完成的事情留到明天去做的。美国作家富兰克林曾经说过：“你热爱生命吗?那么请别浪费时间，因为时间是组成生命的材料。”伟大的发明家爱迪生从小就珍惜时间，经常利用在车上卖报的时间来做实验，累了，就在旁边躺一会儿。渴了，就喝口水，饿了，就吃块面包。牛顿，居里夫人，爱因斯坦……哪个名人不是如此?他们从不停留在昨天，更不空空等待明天。他们利用今天，完成他们想要干的事情。
短短的《明日歌》是一个座右铭，它一直提醒我要把握今天，决不让时间白白流失。从现在开始，不要让时间白白流失!

时间就是生命，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。
我感叹时间过得太快，纯真的童年时光还历历在目，转眼间却已成为一个十岁的小姑娘了。有时看着白发苍苍的爷爷奶奶，会感怀自己哪一天也会垂垂老去。正因为人生短暂，我们才更应珍惜每一个美好的瞬间和每一丝真诚的感动。
有一次，让我的感触很深。当时有考试临近，同学们都在拼命地复习着，而我却在悠然自得地玩耍，一边看着同学们努力地复习着，一边想：唉!用得着这么用功吗，不就是一次普通的考试嘛，难不成考试前这么看看就能拿个一百分。等到考试时，同学们都齐刷刷地拿起笔来写，可是我却坐在那里拿着笔为一道题一个劲地发呆。因为之前我根本就没有复习，所以对于我而言，这道似曾相似的题越看越糊涂。再看看别的同学，有的在冥思苦想，有的还在不停地写着，终于在最后的时候，我也是硬着头皮勉强做了一些。由于是刚考完试，同学们仍然在兴致勃勃地讨论着，看着他们一副欢呼雀跃的样子，我的心就如刀割。想想每当我想要认真复习时，心就不安分地动起来，往往都是半途而废的把时间都浪费掉。
现在我明白了，人的一生很短暂，时间也不会很多，但有的人却能很出色，因为他们把握了时间。有的.人荒废光阴，时间就会变得很漫长，莎士比亚说过：“抛弃时间的人，时间也会抛弃他”的确，正是这个道理吧。所以我们必须珍惜我们现在的时间，就是在珍惜我们的生命。
