The fable of Pony Crossing the River and the case of Yuan Longping taking graduate students illust

"Pony Crossing the River" is a classic fable about a pony who wants to cross a river, but does not know the depth of the river and whether it can be crossed. It asks the squirrel and the cow, but both animals have different answers, causing the pony to be unable to decide. Eventually, the pony decides to try it on his own and walks across the river step by step, discovering that the river is not as deep or shallow as the squirrel and the old cow say.

This story is a good example of the truth that "practice makes sense".

This fable can be linked to the example of Yuan Longping taking graduate students. Yuan Longping is a well-known agricultural scientist who has dedicated himself to the study of hybrid rice to solve the problems of a growing population and food shortages. Some of his graduate students are just starting out in this field and may have some basic understanding of how rice is hybridized and grown, but lack hands-on experience.

Yuan Longping knows that true knowledge and skills come from practice. Therefore, he led the graduate students to go to the rice fields and learn through hands-on practice. They conducted various experiments, such as the selection, planting, and fertilization of hybrid rice, and continuously adjusted and optimized them according to the actual results.

In this way, graduate students not only learn practical skills that are not available in books, but also gain a deeper understanding of rice growth and yield.

This example also illustrates the truth of "practice makes true knowledge". Only through practice can we truly understand the essence and laws of things and master real knowledge and skills. Compared with pure theoretical learning, practice can provide a more intuitive and vivid learning experience, making knowledge easier to understand and remember.

For scientific research and innovation, practice is an indispensable link, and only through repeated experiments and explorations can real results and innovation be achieved.

To sum up, the fable of "Pony Crossing the River" and the example of Yuan Longping taking graduate students well reflect the principle of "practice brings true knowledge". In our life and learning, we should also pay attention to the importance of practice, and have the courage to try and explore, so as to gain real knowledge and skills.

Practice is the only criterion for testing truth.

Answer B: This question examines practice. There is no difficulty, just a reproduction of the basics. The practice of filial piety and true knowledge is to carry the ant to say that practice is the basis of understanding, and b is in line with the topic.

b. This question examines practice. There is no difficulty, just a reproduction of the basics. Practice produces true knowledge, which means that practice is the basis of understanding, and B conforms to the topic.
