我学会了珍惜时间的作文400字【一】
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。
我学会了珍惜时间的作文400字【二】
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。

Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting, playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time.
