总是感叹时间过得太快，纯真的童年时光还历历在目，转眼间却已成为一个十四五岁的小伙子。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。但人生不能只由伤怀组成，我们应该微笑。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。

　　珍惜亲情，它让我们的生命之湖漾起美丽的涟漪。早已熟悉了母亲关怀的问候和父亲沉默的眼神。但只因熟悉，却忘记了在母亲为自己盛饭时说一声谢谢，忘记在父亲抚摸自己的头时有一丝感动，甚至愚蠢地认为这是他们应该做的。直到那天，母亲在夕阳余晖中散开头发，我看到几丝苍白的银丝在绯红的晚风中飞扬，不禁泪流满面。在我看来爷爷奶奶的老是可以接受的，而父母的老却是难以接受的，因为他们曾经如此年轻和美丽。翻着老照片，看着那些风华正茂的笑容，我告诉自己，要珍惜这份亲情，这样才不至于在失去时太难过。

　　珍惜青春，它让我们的生命之歌传到遥远的地方。我们之所以幸福，是因为我们已懂事，但还不用为家庭操心，我们有许多真挚的朋友，我们拥有灿烂的青春。虽然现在的学习生活看起来有些单调，但我却不愿拘泥与此。我喜欢在父母出门时偷偷看场球赛，并为之兴奋或遗憾；我喜欢和朋友们酣畅地聊天，聊过去，现在和遥远的未来；我喜欢在星光的照耀下独自回家，仿佛我就是黑夜的游侠；我喜欢在星期天呼呼地大睡，尽情地享受那份慵懒。我喜欢这种活力和激情的感觉，我想好好珍惜这青春岁月，这人生中最美好的时光。

The Importance of Time
Someone says "Time is money". But I think time is much more important than money. Because money is
spent,we can get it back. However, when time is gone, it'll never come back again.That's why we mustn't
waste time.
But there are still a lot of people who don't know the importance of time. They waste their time playing
games, getting on line and something else. They don't know wasting time means wasting part of their own
lives.
We often say: "How time flies!" So even a second is very important sometimes. We must make full of
time to do anything useful. And in a word, we must save time, and we shouldn't leave today's work tilltomorrow.
