This is what I read an essay along the lines. After reading, I got no small revelation. Just imagine, not a small crocodile Should the courage to try to find another way out, then it can not escape the bad luck of the pond were killed; while the other crocodiles, if they are not complacent, the courage to try, then why would they end up drying up the body of the sad death of end! This shows how important the spirit of courage to try!
Throughout ancient and modern, where Youcheng, who invariably have the courage to try to spirit. Light bulb inventor Thomas Edison in order to find a suitable material for the filament, actually carried out indomitable Rao 8000 several attempts. Initially, he found a 1600 kinds of heat-resistant material, repeated testing of nearly 2,000 times, and found that only platinum is more suitable, but the platinum more valuable than gold, which means that the experiment fails. Faced with this failure, the average person will choose to give up, but he did not, but continues to try to discover the ideal from the plant filament material, has also tried more than 6000 kinds of plants.
Through continuous attempts, Edison finally obtained a great success, has brought to mankind, \"light.\" This \"light\" is light, not so much the electric light, might as well say that the spirit of courage to try to light. In fact, we think it will as long as the thin surprised to discover that he has made a number of achievements in 1000, went so far as no other one is not constantly trying to crystallization. \"An attempt to have a harvest,\" says his words right way out of the secret of his success. Also developed the Nobel detonators found lightning laws Lomonosov, the first aircraft of the Wright brothers flew up into the sky ... ... they have obtained one by one amazing achievement, another of which one must not attempt to spend the fruit of it? Write here, I wonder: In the worship of great men, we should not worship the great figures of the courage to try to create the spirit?
Not only in science need this kind of spirit, we are learning and life, do not they also need the courage to attempt such a spirit? In learning and life, we should try to raise their hands to speak, trying to challenge textbooks, trying to explore co-operation with fellow students, but also try to understand others, concern for others ... ... in the continuing attempts, our intelligence will be increased ; in constant attempts, our capacity will be enhanced; in constant attempts, our humanity will be sublimated. Continue to try, we will be climbing one after another intellectual heights.
My friends, the courage to try to bar! It is almost all the achievements of birth po.
在烈日下，一群饥渴的鳄鱼陷身于水源快要断绝的池塘中。面对这种情形，只有一只小鳄鱼起身离开了池塘，它尝试着去寻找新的生存的绿洲。塘中之水愈来愈少，最强壮的鳄鱼开始不断地吞噬身边的同类，苟且幸存的鳄鱼看来是难逃被吞食的命运，然而却不见有鳄鱼离开。池塘似乎完全干涸了，惟一的大鳄鱼也耐不住饥渴而死去了。然而，那只勇敢的小鳄鱼呢，它经过多天的跋涉，幸运的它竟然没死在半途中，而是在干旱的大地上，找到了一处水草丰美的绿洲。
这是我读的一篇短文的大致内容。读后，我获得了不小的启示。试想，如若不是小鳄鱼勇于尝试，寻求另一条生路，那它也难逃丧生池塘的厄运；而其它的鳄鱼，如果它们不安于现状，勇于尝试，那么它们又怎会落得身死干塘的可悲结局！由此可见，勇于尝试的精神多么重要！

纵观古今，凡有成者，他们无不具有勇于尝试的精神。灯泡的发明者爱迪生为了找到一种合适的材料作灯丝，竟不屈不饶地进行了8000多次尝试。试验初期，他找了1600种耐热材料，反复试验了近2000次，结果发现只有白金较为合适，但白金比黄金还贵重些，这就是说实验失败了。面对这样的失败，一般的人肯定会选择放弃，然而他没有，而是继续尝试着从植物中发掘理想的灯丝材料，先后又尝试了6000多种植物。
通过不断的尝试，爱迪生最终获得了巨大的成功，给人类带来了“光明”。这“光明”之光，与其说是电之光，还不如说是勇于尝试的精神之光。其实，我们只要细细想想就会惊奇地发现，他所取得的一千多项成果中，竟没有哪一项不是不断尝试的结晶。 “一次尝试，就有一次收获”，他的这句话正道出了他的成功的秘诀。还有研制出雷管的诺贝尔、发现了雷电规律的罗蒙诺索夫、第一次架飞机飞上了天空的莱特兄弟……他们所取得的一个个惊人的成就，又有哪一个不是尝试之花结出的硕果呢？写到这里，我在想：在崇拜伟大人物的同时，我们是不是更应该崇拜造就伟大人物的勇于尝试的精神呢？
不仅在科学上需要这种精神，我们在学习和生活中不也同样需要这种勇于尝试的精神吗？在学习和生活中，我们应尝试着举手发言，尝试着向课本质疑，尝试着与同学合作探讨，还应尝试着理解别人、关心别人……在不断的尝试中，我们的智慧将得到增长；在不断的尝试中，我们的能力将得到提升；在不断的尝试中，我们的人性将得到升华。不断的尝试，我们将攀上一个又一个智慧的高峰。
朋友们，勇于尝试吧！它几乎是一切成就的催生婆。
