敬爱的老师们，同学们：大家早上好!今天我们演讲的主题是努力学习，只争朝夕。
年轻是搏击风浪的航船，昂扬潇洒。知识是青春航船的动力，永不衰竭。处在花季中的我们，应该抓紧时间，持之以恒，努力学习，只争朝夕。
为理想而努力，为将来而奋斗，先辈们为我们做出了榜样。
因为努力，安徒生从一个鞋匠的儿子成为童话王子;因为努力，罗曼.罗兰二十年的心血凝结成《约翰.克里斯多夫》;因为努力，巴尔扎克给人类留下了宝贵的文学遗产《人间喜剧》;还是由于努力，爱迪生才有一千多项伟大的科学发明;爱因斯坦才得以创立震惊世界的相对论;先贤古哲才给我们留下悬梁刺股、凿壁偷光、囊萤映雪的千古美谈。
爱因斯坦曾经说过："在天才和勤奋之间，我毫不迟疑地选择勤奋";卡莱尔更是激励我们："天才就是无止境的刻苦勤奋的能力"。长江后浪推前浪，就是我们的雄心;强中自有强中手，这是我们的豪情。让处于学习阶段的我们，像爱迪生、巴尔扎克那样刻苦努力、不懈追求，只有这样，我们才能在学习的道路上将一点一滴的知识积累，才能在人生的旅途中将一方一寸的风景珍藏;只有这样，我们才能实现自己的理想，让生命放射出灿烂耀眼的光芒。
然而，奋发进取并不能只是一朝一夕，要持之以恒，贵在"当下"。
中国共产党创始人李大钊曾说过："我以为世界上最宝贵的是“今”，最容易丧失的也是“今”。正是因为它最容易丧失，所以更觉得它宝贵。"是啊，昨天已经过去，明天尚未到来，我们所能做的只有把握今天。
着名教育家班杰明曾接到一个青年人的求教电话，并约好了见面的时间和地点。待那个青年人如约而至时，眼前的景象却令他颇感意外，大教育家的房间里竟然乱七八糟，狼藉一片。没等青年人开口，班杰明就招呼道："你看我这房间，太不整洁了，请你在门外等一分钟，我收拾一下你再进来吧。"说着，他就关上了门。一分钟后，班杰明又打开了房门，并热情地把青年人让进客厅。这时，青年人的眼前展现出另一番景象--房间内的一切已变得井然有序。可是，没等青年人把问题讲出来，班杰明就非常客气地说："好吧，你可以走了。"青年人一下子愣住了，既尴尬又非常遗憾地说："可是，我，我还没向您请教呢。""这些，难道还不够吗?"班杰明一边扫视着自己的房间，一边微笑地说，"你进来已有一分钟了。""一分钟?一分钟，"青年人若有所思地说，"噢，我懂了，您让我明白了一分钟的时间可以做许多事情，也可以改变许多事情的深刻道理。"向班杰明道谢后，青年人开心地走了。
故事讲完了，很简单，却很耐人寻味。正像故事里所说的那样"一分钟里，我们可以丢掉很多事，一分钟里，我们也可以完成很多事。"一分钟看起来并不起眼，可是我们的人生就是这样由一个个一分钟组成，现在的一分钟很快就会成为过去，将来的一分钟也很快就会变成现在。所以同学们，珍惜时间，就必须从珍惜你的每一分钟做起，从现在做起。只有把握好你生命的每一分钟，你才能踏上成功之路，攀上理想之巅。到达成功的彼岸。
"早岁哪知世事艰"，由于我们的生活环境过于舒适，有些同学走向了生活的误区：抛开学习，恣意攀比，沉迷幻想，徘徊不前。孰不知世界上最快又最慢，最长又最短，最平凡而又最珍贵，最易忽视又最易令人后悔的是时间。古今中外，凡是为人类做出杰出贡献的人，都是从把握今天起步的。

"By! I've finally passed the English level secondary examination!" When Iheard the exciting news, I could not help but cheer up! For I am a grade fourstudents, through the level of junior middle school second grade exam, is hownot easy! Recall several months of efforts and painstaking effort, can not helpbut shed tears of delight.
Remember a few months ago, my mother tenderly stroked my head, kindly said:"Vivian ah, this time everyone in preparation for the level of English leveltest. However, mother believe that as long as you work hard, you are now level 2is also no problem, if passed the level 2 and so on key middle school of time,you will be more than others a 'pass'. Do you have confidence?" Looked at hismom looking forward to the eyes of the eyes and trust, I gently nodded.
Since then, all of my spare time to actively preparing for the exam Englishlevel 2.
For the first time in public English test level 2 training courses, Iactively raise your hand to speak in class, the teacher praised me know really alot. Home can be a problem, I will betray oneself. Sixty way choice, thinkingalong while, finally finished only guessing. The next day to listen to theteacher announced the answer, 60 choice was wrong two way. A failure is not letme lose confidence, on the contrary, I saw the hard way, take my spirit. Fromthen on, every time I class carefully take down the content of the teacher. Ifthere are any don't understand the question, I asked my father when I came back,until we understand.
