Finish this poem, then choose your favorite two sentences and tell me your understanding.

1. It's hard for you to understand what you get from the paper. You never know what you have to do.

It is emphasized that the knowledge gained from books is shallow and can only be turned into your own things through personal practice. "practicality" has at least two meanings: first, it is practical in the process of learning, and what you think, do and talk about in the process of learning is a kind of "practicality" for students. Don't we advocate "heuristic method" to arouse students' initiative in learning? It is a practical activity to let students ask questions, discuss and practice in class. Physics, chemistry, biology and other courses are almost inseparable from the "dedication" of students. Even though ancient people mainly studied literature and history, there was a problem of "dedication" in the learning process. Learning article study's poems is a kind of "dedication". Isn't there an old saying that "you can recite poems by familiarizing yourself with 300 Tang poems?" If you understand the connection between articles, you should also practice writing by yourself, otherwise, no matter how much the teacher talks, the students' articles will still be poor. The second is "practice" after acquiring knowledge. This "practice" is social practice, through which we can test learning, turn book knowledge into our own, use it for ourselves, and consolidate and deepen what we have learned.

2. Ask where the canal is so clear, because there is running water from the source.

There are two poems in Zhu's Random Thoughts on Reading, "Ask why the canal is so clear that there is flowing water at the source". The author asked: Why is this "half-acre square pond" so clear? And answer yourself: because this source of living water is constantly replenished, it is so clear.

This beautiful picture of natural scenery is refreshing. What is even more amazing is the reading method of the title and the feeling of reading this book. Suddenly, this beautiful artistic conception was sublimated and integrated with reading. It turned out that what Zhu, a great scholar, realized in praising reading, the carefree, clear and lively feeling in his mind was vividly depicted by the reflection of ponds and clouds. Why is his mind so clear? Because there is always new knowledge in books, like running water, which is constantly supplemented to him.

Zhu used these two poems to illustrate that life is the source of writing. Only by observing attentively can we find the source of living water, draw nutrition from it and be a conscientious person in life.

Everything is clear, everything is learned, and people's understanding is an article.

The couplet "Everything is learned, and people's understanding is an article" is a traditional concept of Confucianism, which expresses the side of Confucianism's entry into the WTO and is also one of the feudal moral standards. A Dream of Red Mansions expresses anti-feudal thoughts, that is, anti-feudal orthodox thoughts, so Zhi Yanzhai will rate it as "extremely vulgar".

So is the idea conveyed by this couplet good? If it was in the era of Cao Xueqin or Lu Xun, it would definitely not be good. Because when some people claim that they know the world very well and are considerate, we are either depressed about whether we can reach this level or struggling on the hunger line like Ah Q, but it's different now. Any comrade who can answer questions online can be in the same position as Ah Q, so we all think couplets are good. The fifth couplet in A Dream of Red Mansions. In other words, it is a kind of learning to reason and master the laws of facts. If handled properly, the law summed up is the article.

I remember the first time I saw this sentence, when my family of three went to my father's house and hung it in his hall. It was a couplet written by an old friend, which left a deep impression on me. I think it makes sense, and it is a kind of wisdom and realm of human beings. The father also told his daughter the meaning of this sentence. But I didn't pay attention to where this couplet came from. I didn't understand the reason until I accidentally saw it again on the Internet and checked some information. It turns out that "everything is clear and knowledgeable, that is, the article" comes from the fifth time of A Dream of Red Mansions. Cao Xueqin mounted a couplet in Wang Xifeng's "office" and savored it carefully, which is a wise saying.

This couplet is Cao Xueqin's evaluation of Wang Xifeng. She manages Jia's family affairs, both inside and outside. She can't manage the affairs of that big family without shrewd mind, smooth means, provocative personality, broad vision, rich knowledge and ability to grasp the scale of things.

The world understands "having" knowledge, and human feelings are proficient in "writing". "The spirit is everywhere, and the spirit will be flat when you learn deeply." This is a kind of knowledge and a profound understanding of society and life. I have studied hard for ten years in my life. Compared with the knowledge in the world, there are countless books, but they are only nine Niu Yi hairs. The school only taught us basic learning methods and basic education. But in this complex society, each of us is constantly learning and exploring, and constantly feeling the society and the world.

"The world is cold" embodies a kind of maturity and intelligence, and "the way of the world" highlights age and skills. In this "relational" society, Tao has ascended to heaven, but Tao has failed to help.

Once upon a time, thinking about myself, I was like a locomotive with full horsepower, just rushing forward, but rarely taking care of the complicated chores around me and losing many opportunities; However, now I often have a normal heart and a grateful heart, "let nature take its course, regardless of gains and losses" and "don't take pleasure in things, don't worry about myself". Now I prefer to experience myself, feel life and taste life.

4. Falling red is not heartless, but turning into spring mud will protect the flowers.

"Falling red is not heartless, but turning into spring mud will protect flowers more." The poet turned from expressing his feelings of parting to expressing his ambition to serve the country. On the other hand, in the words of Lu You: "Scattered into mud, crushed into dust, only the fragrance remains." Falling in love originally refers to the flowers blooming on the branches, but it is not something without feelings. Even if it turns into spring mud, it is willing to cultivate beautiful spring flowers to grow. Not for the unique fragrance, but to protect the flowers. It shows that although the poet is divorced from officialdom, he still cares about the fate of the country and never forgets his ambition to serve the country, which fully expresses the poet's strong feelings and becomes a famous sentence handed down from generation to generation.
