如何珍惜学习时光作文【一】
时间，他是人们生命中的匆匆过客，往往在我们不知不觉中，他便悄然而去，不留下一丝痕迹。人们常常在他逝去后，才渐渐发觉，留给自己的时间已经所剩无几。也正是如此，才有了古人一声叹息：少壮不努力，老大徒伤悲。
怎样才能留住这个来也匆匆，去也匆匆的“朋友”呢？榜样的力量是巨大的。
爱因斯坦即使是在做家务时也从不虚度时间，而是挤时间来思考。有一次，他推着一部婴儿车在伯尔尼的马路上散步。他迈着沉重的步子，每走十几步就站住，从上衣口袋里拿出铅笔和纸片，写下几行数字和公式，低头看一看甜睡的儿子，抬头看一下钟楼上的大钟，又向前走去……
事实告诉我们，只要我们愿意，时间是可以支配的。就像鲁迅先生说的一样：时间就像海绵里的水，只要愿挤，总还是有的。
而能否把握时间，做时间的主人往往决定着一个人一生的命运。陶渊明说过：盛年不重来，一日难再晨。及时当勉励，岁月不待人。人生短短数十秋，想要在如此短的时间内，取得成功，登上人生的顶峰，谈何容易。也正因为如此，珍惜时间就显得异常得重要。每个成功人士的背后往往有一段珍惜时间的故事。
奥地利著名作家莫扎特，连理发时也在考虑乐曲创作，常常情不自禁地停止理发，记下他构思出的新乐曲。他说：“谁和我一样用功，就会和我一样成功。”
莫扎特说得不无道理，也许我们和他一样用功，不一定会象他一样的成功，不一定能达到他所能达到的高度。但至少我们努力了，至少我们达到了我们所能达到的最高处。我们就能够站在人生的顶端对人们说：我尽力了，我并没有浪费命运留给我的一点一滴的时间。
但丁说过：一个人愈知道时间的价值，愈感觉失时的痛苦。而世界上有太多太多的人不知道时间的价值了。或许在嬉戏玩闹的十个人中，有九个人知道：一寸光阴一寸金，寸金难买寸光阴。但他们却不一定懂得这句话的真实意义。倘若他们懂得，会如此快乐吗？
无论时间有多么的紧张，只要我们愿意，他会源源不断的到来。
珍惜时间，就是珍惜生命。充分利用命运给我们的每一分，每一秒。不要成为时间的奴隶，做时间的主人。到那时，让这一个匆匆过客，永伴你我左右。
如何珍惜学习时光作文【二】
仔细回想那些烟雨蒙蒙的已逝时光，曾经面对清碧泻绿的小径，问花开花落为谁？可惜那些十分精彩却不懂得珍惜的日子已不再来。也明知这个世界不是什么都好，它既有团圆，也有离别；既有翠绿，也有苍凉，更有人生旅途中的许多无奈。然而，感受时光对自己的重要，渴望生命创造辉煌的信念始终没有放弃。一个人拥有一次生命极不容易，活着就该潇潇洒洒，充分享受生命带给你的阳光。
回想过去那些星星点灯的夏夜，多少次收拾起凌乱的思绪，收藏起咸湿的情感，放飞痛苦和忧伤，紧紧把握心灵的金丝线，昂首挺胸去迎接黎明曙光的心情。走出了内心的荒芜，没有了浮躁与娇饰，成熟的心智增添了份量，帅气的风采从微笑中透出，睿智的心驰骋于浩瀚长空。
跋涉人生的时光里，曾经有过徘徊和低迷的日子，为了不经意的情感与世事损伤大脑，为不能给自己丁点快乐而失意。有过许许多多的遗憾，也有过许许多多的机缘。当面对这些时，总觉得未来的日子很长也很美，总会有喜悦与欢乐，然而这一切都随时光的流逝淡淡远去。
伫立时光的岸头，可以尽情舒展自己的心绪，所有的激情都会潇潇洒洒同你而舞。你可以任轻风吹拂你疲惫的身心；任凄楚婉约的笛声长空自横；任时光流逝写下岁月的沧桑。眺望人生旅途的每个驿站，你会深感一种启明星的照耀，你会心甘情愿地为之深情祝福。拥有珍惜时光与默默体验人生智慧的宽阔心境，就会知道生命永远蕴含于活泼的时光之中；就会懂得人生不一定全是波澜壮阔，而平淡无奇才是真，也就会真正明白人生最该珍惜的是宝贵的时光。故而从感叹中觉醒，再不能得过且过，把有限的生命赋于你生活的时光是最为重要的，时刻用激情浇溉心灵，充实人生的脚步，才不枉人生宝贵的时光。
属于人的时光就像四季的枯荣与轮回一样，是一次自然的流程，我们无法抗拒。体验过去的匆匆岁月，不管是苍老的心，还是活泼的心，我们都应该心存一份感激，应该倍加珍爱人生，珍惜时光。没有经历时光的隧道，又怎么能跋涉人生之旅？我的朋友，迈开坚实而沉稳的步伐，脚踏实地地奔向远方吧！
珍惜时光，就是珍惜人生。

如何珍惜学习时光作文【四】
劝君莫惜金缕衣，劝君惜取少年时;一寸光阴一寸金，寸金难买寸光阴……时间对每个人来说都是很珍贵的，我们要珍惜时间。
人生短暂，珍惜时间就是珍惜生命，只有在短暂的人生中，多做一些有意义事才能更好的体现人生的价值，所以珍惜时间，对于实现人生价值有重要的意义。
我们常常说要珍惜时间，可是时间就是那么多，到底该怎么珍惜时间呢?
首先，珍惜时间就应该提高办事效率，办事效率提高了，就会节省大量的时间。就拿我自己来举例吧，以前我背课文总是花上一两小时，，一边背课文，一边看电视或听音乐，觉得自己一心可以二用，美的不得了。可是现在上了初三，学习时间越来越紧张，作业越来越多，再背课文用上一两个小时，那做作业就得熬夜了。于是我就压缩背课文的时间，专心致志的背下来，不到半个小时就能完成，我才发现原来我的学习效率是那么低。长此以往，我得浪费多少时间呀!
其次，珍惜时间就要合理地利用时间，能更好得利用琐碎时间。鲁迅说：“时间就像海绵里的`水，只要挤总会有的。”“哪有什么天才，我不过是把别人喝咖啡的时间都用在
你想实现人生价值吧，那就珍惜时间吧!
