Today, when I looked through the accumulation book, my eyes inadvertently fell on the following sentence:“ If you don't go into the water, you won't swim all your life; No, Yang fan can't go boating all his life”
今天，我翻阅积累簿时，目光无意间落在了这样一句话上：“不下水，一辈子不会游泳；不杨帆，一辈子不会撑船。”
I couldn't help thinking of the little story my mother told me before. Zhao Kuo was the son of Zhao she, a famous general in the Warring States period. He had read many military books since childhood and was full of talent, but he lacked practical combat experience. He could only write strategies on paper. But king Zhao listened to slander and replaced general Lian Po with Zhao Kuo. As a result, Zhao Kuo was shot dead by Qin soldiers with random arrows, and all 400000 soldiers led by him were killed in the pit
我不由自主地想起妈妈以前给我讲的小故事。赵括是战国名将赵奢的儿子，从小读过不少兵书，满腹才华，但缺少实战经验，只能在纸上写一写策略，可赵王听信谗言，把大将廉颇换成了赵括，结果赵括被秦兵用乱箭射死，而带领的四十万士兵全部被坑杀。
Zhao Kuo“ Talk on paper;, Only studying theory and lack of practice led to the defeat of the war, which confirms the above aphorism. Madame Curie said:“ The road needs to be taken by oneself, so that it can be wider and wider” Therefore, if you want to do a good job, you must have the courage to try. Only after many times of practice can you obtain valuable experience, so as to continuously improve the level. If you only learn but don't practice, you will only fail like Zhao Kuo in the end
赵括“纸上谈兵”，只研究理论、缺乏实践而导致战败，这印证了上面那句警句。居里夫人说过：“路要靠自己去走，才能越走越宽。”所以，想要做好一件事，必须要勇于尝试，只有多次实践之后，才能获得宝贵的经验，这样才能不断提高水平，如果只学而不练，最终只会像赵括一样走向失败。
I can't help but think of an example. Foreigners asserted that they could not find the remains of Quaternary glaciers in their compositions in China, but Li Siguang never believed it. He personally traveled mountains and rivers to look for them everywhere. Finally, he found the remains of glaciers near Datong, Shanxi Province, and found many strong evidence in Lushan Mountain, Taihang Mountain and other places, pushing over the foreigners'“ Conclusion”. This example also shows the importance of practice. If Li Siguang did not make in-depth exploration, he could not overturn the remarks of foreigners and promote the great progress of China's geological cause
我不禁也想起了一个事例。外国人断言在中国作文找不到第四纪冰川的遗迹，可李四光却始终不相信，他亲自跋山涉水到处找寻，最终在山西大同附近找到了冰川遗迹，又在庐山、太行山等地发现了许多强有力的证据，推翻了外国人的“定论”。这个例子同样说明了实践的重要性，如果李四光没有深入探索，就不能推翻外国人的言论，也不能推进我国地质事业大步前进。
Practice is really very important. We primary school students have science classes. Doing scientific experiments can make us more vividly and deeply understand scientific principles. For example, teacher Ye assigned us to go home to do the hot air experiment last semester. I made a balance model with a chopstick, two paper cups and two thin lines at home. By heating the air, I quickly understood the principle that the hot air is light and will rise. It's really“ It's easy to get what you get on paper. You must know it and practice it” Ah
实践确实非常重要。我们小学生就开设有科学课，通过做科学实验能够让我们更形象深刻地理解科学原理。比如上学期邺老师布置我们回家做热空气实验，我在家用了一根筷子、两个纸杯、两条细线做了一个平衡模型，通过加热空气很快就领悟了热空气较轻且会上升的原理，真是“纸上得来终觉浅，绝知此事要躬行”呀！
practice produces true knowledge. We should learn to practice more and have the courage to try since childhood. We believe that the door to success will eventually open to us
实践出真知，我们从小就要学会多实践、勇于尝试，相信成功的大门终向我们打开！(文/林拓航)
