As the saying goes: practice makes true knowledge.

It's true. No matter how rich a person's knowledge is, he knows astronomy above and geography below. If he lacks practice, he can only wait and die, and can't do great things.

We are no strangers to the battle of Changping in history. It is a great tragedy that Zhao's 400,000 troops were buried alive by Qin. The reason is just that Zhao Kuo, an armchair strategist, left regrets in history. If Zhao Wang is good at employing people and replaces Zhao Kuo with Lian Po, I think history will be rewritten. This is a lesson of blood, we should always keep it in mind and always tell ourselves to be good at practice.

Crossing the long river of history, let's go back to the present.

Isn't the captain's son a good example in the material? Of course, sailing needs technology, which can be said to be the most important, but once it is divorced from practice, it can only end up like the captain's son. It's pathetic. If the captain has a little sense, he will teach his son the skills of sailing, and at the same time, he will practice at sea, so that he can exercise his courage and skills in sailing in the rough sea. I think his son will be like him, perhaps stronger than him, and become the second king of navigation after him.

Sailing is like this, so is learning?

A person only knows how to learn, but keeps learning without thinking. No matter how much he learns, he will never achieve great things. In study, we should study hard. When I say study hard, I don't mean that you should keep studying and not relax. You only have a firm grasp of knowledge, and you can't use it without practical ability.

Throughout the ages, no successful person has been practiced. Edison made thousands of experiments to invent the light bulb; In order to get the relationship between magnetism and electricity, didn't Faraday get it from practice again and again? Wait, of course, their grades are very good and they have made contributions to the scientific cause.

Recently, I read a passage in a magazine: Every time I take part in the Olympic Games of China Student Union Examination, the winners are all from China; The United States will create every meaningful invention, most of which will come from Americans. I think once China and the United States complement each other, they will certainly achieve greater success.

Finally, I want to say, let's use knowledge to drive, support practice and advance for our ideals.
