Ordinary people's rice bowl

Chapter 74 Returning to the Sea of ​​Questions
Tian Cheng ran out from Lao Mu's house and went straight to his own pig farm. When Lao Zhao saw Tian Cheng's arrival, it was like seeing a savior.

"Quick, our sow gave birth again!" It was a very common thing, but for Lao Zhao, he never dared to do it by himself. It was all watched by Tian Cheng himself. Every sow in the farm affects his nerves, and every sow gives birth to a piglet, and he never dares to take it lightly. It is the lifeblood of the breeding farm.

Because Tian Cheng was running very fast, as soon as he stopped, he stood there gasping for breath. He was really out of breath, and asked Lao Zhao intermittently, "Did you have a normal delivery?"

"En." Old Zhao coughed, and responded heavily.

"That's okay!" Tian Cheng put his heart in his stomach, and he was relieved when he saw the sow giving birth in the delivery room. A bunch of cubs beside the sow were suckling, and Mu Zhen was There stared curiously.

It was another litter of piglets that were bright in the dark, Tian Cheng's face showed joy, and he called out happily: "Mu Zhen, come here!"

Mu Zhen raised her head abruptly when she heard this, and followed Tian Cheng out of the delivery room.

"I came from your house just now, and your father told you to go home and not let you do it!" Tian Cheng said, took out five ten-yuan bills from his pocket, handed them to Mu Zhen, and said, "You have been here for so many days , I won’t give you any other things anymore, this 50 yuan, you can use it to buy some school supplies, it’s also a little uncle’s kindness!"

Mu Zhen didn't pick it up. He felt that his father's asking him to come was the same as mowing grass for cattle back then, but the way of punishing him was different. Besides, he didn't do any work here, so how could he accept Uncle Tiancheng's money?

"Thank you uncle, I can't ask for this money. I've lived a very happy life here, how can I ask for your money?" Mu Zhen said very sincerely.

"It has nothing to do with whether you are happy or not. If you are here to help, why don't I show my appreciation? Besides, you see that the sow has given birth again. This is a happy event. Giving you some money is also a happy gift!" As Tian Cheng said, he put the money directly into Mu Zhen's hands, and urged casually: "Take it quickly, if you don't take it, uncle will be angry!"

Seeing Tian Cheng's angry expression, Mu Zhen reluctantly took the money, and said in a low voice, "Thank you uncle!"

When Mu Zhen returned home, the sun had already slid to the top of the west mountain. Mu Yan, who was preparing dinner in the kitchen, saw her brother coming back, and said hello: "Brother, come and cook the pot for me."

Without saying a word, Mu Zhen went directly into the kitchen, picked up a large handful of firewood in front of the pot door, and stuffed it into the bottom of the pot. The fire at the bottom of the pot was immediately extinguished by the firewood, and a puff of thick smoke poured over immediately. The two of them coughed non-stop, and Mu Yan smiled and said, "Haven't you learned how to cook a pot in the pig farm?"

"I didn't go there to learn how to cook a pot. How can I learn? Besides, I went there to exercise my hands and feet, and see how I can blow it!" After speaking, one hand picked up the firewood with a fire stick, and then lay on the ground. The curtain of the pot door blew up.

Strange to say, when the embers met Mu Zhen's breath, there was a sudden "boom", and Xiongxiong burst into flames.

"It seems that I have learned it. I choked me with smoke on purpose just now!" Mu Yan, who was standing in front of the pot and holding a shovel, joked with a smile.

"How could I be willing to choke you? You are alone at home, what about their people?" Of course Mu Zhen was referring to her parents and Mu Bao.

"You don't even dare, Mu Bao went down to the ground, they should be back in a while, let's cook quickly, we are still waiting for dinner!" Mu Yan responded while turning over the pot with a shovel. dishes.

"When I came just now, Uncle Tian Cheng gave me 50 yuan and took it out!" Mu Zhen said happily.

"Why are you giving so much?" Mu Yan was a little surprised.

"That's right, I didn't expect to ask for money when I went there to help! Uncle Tian Cheng insisted on giving it to us, so we don't want to make him angry!" Mu Zhen said and put it back in her pocket.

While the two were talking, Lao Mu and Xiuhua entered the courtyard gate, and Mu Bao bounced to the kitchen with a few small fish strung together with foxtail.

"Look at the fish I caught, you can make fish soup!" Mu Bao happily said to Mu Zhen and Mu Yan.

"It's almost the same as feeding the ducks!" Mu Yan said in a slightly mocking tone.

"You think that's all there is, there are still more in our university!" Mu Bao said, pointing to Lao Mu outside the house, Mu Yan looked back, and sure enough, Lao Mu was holding several strings of such small fish in his hand, and was about to Find a water basin and put it down!
The family was busy with their own work, and quickly cleaned up the fish, fried them with oil, and then cooked a pot of delicious fish soup.

After dinner, Mu Yan and Mu Bao followed Xiuhua to the side of the road to cool off, and Lao Mu and Mu Zhen were left at home. Lao Mu took out a few exercise books that he bought from the bookstore this morning, and said to Mu Zhen: "The recent education reform , I am working on a plan, the country advocates that students should start with reading, writing, listening, speaking, and practice, and do a good job in classroom teaching. Now take this vacation, you should practice hard, otherwise you will have no time to practice after entering school!"

Mu Zhen understood that Lao Mu was going to impose the elementary school teaching on herself again. He looked at the stack of books without saying a word, even if he was [-]% dissatisfied, so what?Who made himself fail to achieve satisfactory results in this exam?Mu Zhen blamed herself silently.

"I carefully selected these books from the bookstore. You have to be proficient in them." Old Mu repeatedly emphasized that he was afraid that Mu Zhen would be lazy.

Mu Zhen took those books, and then went back to her own study next to the kitchen. He knew that Lao Mu's idea was to let him practice these exercises repeatedly without taking his eyes off the books from now on, from tonight onwards. This is the teaching reform in Lao Mu's heart.But the teaching reform is another idea in Lao Mu’s mind. He has thought more than once that education is to give full play to the subjective initiative of students, and classroom teaching is to make students the protagonist and the teacher a supporting role. How to guide students to understand what the classroom is about to say Knowledge is fundamental, and Lao Mu, who has this kind of educational thinking, always deviates from his own teaching philosophy when guiding Mu Zhen, and engages in special problem-sea tactics. In his eyes, for his son, he just needs to practice more. Practice makes perfect.

From then on, Mu Zhen never went out of the door again, and she read the exercise books bought by Lao Mu in her room every day. Whenever Lao Mu was free, she would sit down to check Mu Zhen's study situation, or choose a book. Let's test Mu Zhen in the following unit test.

In Mu Zhen's view, those questions all have similarities, and if you continue to practice deliberately, it is tantamount to doing useless work. Even so, Mu Zhen is unwilling to raise objections to Lao Mu. Nagging, worried that this would stimulate Lao Mu and arouse his anger, worrying that Lao Mu would misunderstand his study.

Mu Zhen's worries were not superfluous at all.Mu Zhen always feels that the most important thing in mathematics is the mastery of formulas and theorems. Mastering those basic formulas and theorems will lay a solid foundation, just like the foundation of a house. The formulas and theorems are the foundation, and the exercises are on it. It's as simple as building a house with bricks.

Mu Zhen has never encountered any problems, but the facts are not as he imagined. In this exercise book, there is a problem that he cannot overcome. When he checked the answer, the answer was as simple as a few words - use the method of proof by contradiction.The method of counter-evidence may have been taught by the teacher in the last month, but because of the depressing days in the later period, I couldn’t concentrate in class at all, so listening to the lecture was "to the ear", and the knowledge taught by the teacher entered from the left ear and slipped from the right ear. After leaving, there were not a few words in her mind, and the special method of proof by contradiction was not mentioned in the textbook, so Mu Zhen felt at a loss.

During lunch, Lao Mu came back. Mu Zhen took this question to Lao Mu. Yuan Bing from the department, he should have a way to solve this problem.

"I can't prove this contradictory method well either. In the afternoon, I'll ask Yuan Bing from the upper teacher's college in the neighboring village." Old Mu said without digressing.

Although Yuan Bing's family lives in Liji, which is adjacent to Xiaowangzhuang Village, the responsibility field of his family is only separated from the responsibility field of Lao Mu's family by a irrigation ditch. When he usually works, Lao Mu sits on the ground to rest. When Bing's father was around, the two would sit on the ground and chat for a while. Yuan Bing's father was an accountant in Liji Village and a capable person in the village. Lao Mu admired him very much, especially after his son was admitted to university. He was even more impressed with Yuan Bing's father.

That afternoon, Lao Mu went to the piece of land next to Yuan Bing's house. While working in the field, he turned his eyes to the direction of Liji Village from time to time. Just yesterday, he saw him and his father in the field The figure of working, why haven't they come today?As Lao Mu thought about it, he became more and more anxious waiting.

He looked up and saw that the sun had already crossed the treetops in the distance. Lao Mu felt that there was no hope for Yuan Bing and his son to arrive today. He decided to put aside his work and take his son to Liji to visit this outstanding student in the mathematics department.Thinking of this, Lao Mu no longer wanted to work in the field, but walked up from the rice field. He didn't care to wash off the mud on his feet, he just packed his things hastily, and went straight home. Hua looked at his receding back and let out a long sigh.

After returning home, without saying a word, Lao Mu pushed out his old Long March, told Mu Zhen to take the math exercise book, and went to Li Ji together.

Liji Village is not big, with about [-] people. Yuan Bing's family lived in the middle of the village, and Lao Mu found the door after a little searching.

"Big brother, what gust of wind brought you here!" Yuan Bing's father greeted Lao Mu in surprise when he saw Lao Mu who had pushed open the gate and entered the courtyard.

"It's so close, let's drop by your house, is Yuan Bing at home?" Old Mu asked.

Before Yuan Bing's father could speak, he heard Lao Mu calling his name in the house, so he got up and stood at the door to greet Lao Mu: "Uncle Mu, I'm at home!"

"It just so happens that my son has a math problem and wants to ask you for advice, so why don't we bring him to your door!" Old Mu said politely.

"Look at what you said, you are really polite, as long as you can help, you will definitely help!" Yuan Bing felt that Lao Mu said this a little flattering himself, and felt a little embarrassed.

"Take it out quickly and let your brother see it!" Old Mu said to Mu Zhen who was standing behind the bicycle.

Mu Zhen didn't speak, just took out the exercise book, and turned out the question from the folded pages.

Yuan Bing glanced at it, smiled and said: "This question is a traditional question. To put it bluntly, I don't know how to test it at all. It only exists as a proof method. This proof method is rarely used. It seems like you asked him to do this. Is it of no use?"

Hearing what Yuan Bing said, Lao Mu felt a little embarrassed, and didn't know what to say.

Lao Mu's discomfort has already attracted Yuan Bing's attention, and he felt that Lao Mu might not understand what he said, so he explained: "I'm not saying you can't do it, but doing it doesn't necessarily increase your knowledge. It's a bit difficult, I'll write it down to prove the process, let him understand it, and see if he can understand it."

Then, he took out the paper and pen from the desk drawer, and after a while, he wrote down the proof process completely, handed it to Mu Zhen, and said, "See if you can understand, there are very few such questions, and I have only been exposed to them." There are three or two, if you understand, I don't need to explain!"

Mu Zhen looked at the proof process carefully, nodded, and said that the solution is now. Seeing that Yuan Bing solved the problem so quickly, Lao Mu showed a friendly smile: "Thank you!"

"Neighbors, how can you be so polite!" Yuan Bing's father hurriedly replied.

On the way back, Lao Mu thought about Yuan Bing's words: "It's useless! Could it be that I was wrong? If I didn't encounter this kind of problem, would I still take Zhen'er to ask for a teacher? Students should practice more. That's right, he is a young man, he still doesn't know enough." Old Mu still insisted on his point of view, learning is to practice more, and there is no room for ambiguity.

Under Lao Mu's persistent persistence, Mu Zhen's life could not get rid of the shadow of the sea of ​​questions, and she still insisted on repeating the same learning every day, and felt a little bored.
