"What! elementary school knowledge?" the five students in the class were dumbfounded.

At this moment, the feeling in their hearts is as if asking a high school student to do addition, subtraction, multiplication and division in elementary school is simply overkill, killing chickens with a knife.

The corners of Yan Yeguang's mouth curled up a little.

"That's right, it's to start reviewing the knowledge from elementary school. So now Fang Nan, you recite the multiplication formula for me. ”

Fang Nan stood up with disdain. Humming in the mouth: "One by one gets one, two two gets four, three three gets nine...... Ninety-nine-eighty-one. ”

As long as you have been to school for a few years, you can memorize this multiplication formula smoothly, let alone a high school student. Fang Nan didn't have to make half a effort to recite this multiplication duke.

The curvature on the corner of Yan Yeguang's mouth became more and more obvious. He nodded: "Very good, Fang Nan, your foundation is very good, then below, I will ask you a very simple question, you must answer it for me within 5 seconds." Otherwise, you will be punished for copying the multiplication formula 100 times!"

In the end, Yan Yeguang's tone suddenly became sharp. The five students in the class clearly felt a hint of coolness.

Fang Nan scratched his head and said to Yan Yeguang: "Teacher, don't be too difficult, I won't be too difficult." ”

"It's not difficult, it's a question that a primary school student can easily answer. Okay, let me ask you, what is the sum of 35 plus 26 multiplied by 3? Answer my question in 5 seconds!" Yan Yeguang's eyes lit up in vain as he spoke, locking on Fang Nan.

"This ...... 35 plus 26 equals ...... 61, 61 times 3 equals ...... 183!" Fang Nan was busy counting in the corner, and even used his fingers during the process.

"You used, 6 seconds, to give me 100 times of the multiplication formula before school. While Fang Nan said the answer, Yan Yeguang pressed the button on his watch. Chen Luobin, you look at me, I look at you, and they all realize that this is a conspiracy prepared in advance.

Fang Nan stuck out his tongue with a disgraced face, and sat down unwillingly.

Yan Yeguang looked at the five students in the class, and said sternly: "The college entrance examination is like a battlefield, if you waste time because of a simple calculation question, then you haven't finished four-fifths of a paper, and the time for the exam will come." Then the results of this subject can also be imagined!"

After a pause, Yan Yeguang said again: "You study all day long in those repetitive exercises, and often you will feel that you don't have enough time. What is the reason for this? It is because your foundation is not solid! If a student with a solid foundation does a college entrance examination paper, he will definitely be able to give himself enough time to check the questions on the examination paper!"

As he spoke, Yan Yeguang took out a large stack of papers from his briefcase and sent them to them separately.

"These are the most effective multiplication and division addition and subtraction formulas, you memorize them, and I will ask them separately in the next class, if anyone still can't answer within the time I set. Then whoever will copy these mantras a hundred times like Fang Nan!"

My God, this guy is simply a devil! Chen Luobin glanced at Yan Yeguang, Chen Luobin did not agree with Yan Yeguang's corporal punishment measures, but Chen Luobin was quite in agreement with his teaching model. If these additions, subtraction, multiplication and division are likened to the stepping stones of a tall building, then the knowledge of high school and college is like the main body of this tall building. But if those cornerstones are not strong, one day this high-rise building will not survive the test of wind and rain and collapse.

The time of the two classes passed in a hurry. Yan Yeguang talked about some of the most basic knowledge, but none of the 5 people in the class didn't pay attention to what Yan Yeguang said because it was too superficial.

After class, Yan Yeguang lit a cigarette and stood on the podium and did not leave.

"Chen Luobin, come on. Yan Yeguang said.

"En?" Chen Luobin walked to Yan Yeguang's side with some surprise.

"Come and smoke a cigarette. Yan Yeguang handed Chen Luobin a cigarette.

Yan Yeguang's move made Yuzu and Fang Nan swallow their saliva secretly.

Chen Luobin hesitated, but still took the cigarette. He pulled out a lighter and lit it for himself.

"What happened the other day, how could you fight with people outside?" Yan Yeguang asked.

"Oh, it's nothing, that kind of thing doesn't happen in the future. Chen Luobin replied.

Yan Yeguang glanced at Chen Luobin and said, "You don't have anything to do, I'm also a young man." How can a young man be called a young man if he is not vigorous? But think about it, if you are injured, the person who hurt you will come out after squatting for a few years. And if you end up with a lifelong disability, what will you do in the future? Don't be rash, think more about yourself and your family, if those hooligans come to you again, you tell me, I'll settle them!"

Yan Yeguang said this, how could Chen Luobin not know? But what happened that day really happened for a reason, and he Chen Luobin would not make a move unless he had to.

However, what Yan Yeguang said was quite touching to Chen Luobin, Chen Luobin nodded and said, "Teacher, don't worry, I won't have any problems in the future." ”

"Well, that's fine. ”

While they were talking, a low old man walked in the doorway. The old man had unkempt gray hair and was dressed in old clothes that had been washed a little white. His eyes were cloudy, and he looked only a little better than the beggars on the street.

When Yan Yeguang saw this old man, he quickly threw away the cigarette butt in his hand. He bowed to the old man and said, "Teacher, you're here." ”

The old man put his hands behind his back, with a leisurely expression, as if he didn't hear Yan Yeguang's words, and walked straight to the podium. I found a bench and sat down.

Chen Luobin found that Yan Yeguang's head was sweating. Yan Yeguang said to the five students in the class: "This is Teacher Liu Songquan Liu, who will teach you Chinese in the future." Mr. Liu was my homeroom teacher in high school, and his literary skills are very profound, and I hope you will gain something in your future study and life. ”

After speaking, Yan Yeguang bowed to the old man again: "Teacher, I'm leaving." ”

"Yes. The old man snorted coldly, and his voice was like that of a eunuch in the palace.

Yan Yeguang hurriedly wiped the sweat on his head, and hurriedly left as if he had met a bad star.

Everyone looked at this strange old man a little strangely, and they all wanted to find some clues from him, but this old man was dressed in cloth and dirty, and it was really impossible to hook him up with his mentor.

The bell rings. The old man's eyes, which had been slightly closed, suddenly opened. It scared them a lot.

"Class~~" The old man stood up lazily, and the two words that came out of his mouth seemed to be weak. Everyone is speculating whether this old man is about to be buried in the ground?

"You stand up and recite a song of Li Bai's "Silent Night Thoughts" for me. The old man trembled and raised his arm and pointed at Chen Luobin.

Chen Luobin stood up, cleared his throat and said: "The bright moonlight in front of the bed, suspected to be frost on the ground, raise your head to look at the bright moon, and bow your head to think of your hometown." ”

"Yes, it's a good back. Let me ask you, why does Li Bai miss his hometown?" the old man looked at Chen Luobin and said.

"Because...... From the bright moon, it can be seen that when Li Bai wrote this poem, it was the Mid-Autumn Festival, when the moon was full, and the Mid-Autumn Festival is a traditional Chinese festival that represents reunion. And Li Bai was alone, seeing the bright moon in the sky, and hearing how many people were reunited together, and only after comparing his own situation did he feel homesick. ”

After Chen Luobin finished speaking in one breath, he couldn't help but feel complacent, he shouldn't be able to find anything wrong with his words. But when he raised his eyes to look at the old man, the old man's gloomy face made him feel uneasy.

"You're right, but if the question is 10 out of 10, I can only give you 5 points!"

"What?" Chen Luobin was a little confused, did this old man deliberately make things difficult for me? Chen Luobin thought so.

"Surely you want to know why? Okay, I'll tell you. Li Bai's poem embodies more than just homesickness. Since he misses his family when he is young, why should he stay in the field? He is free and can go home early to reunite with his family? His poem "Silent Night Thoughts" actually reflects his unwillingness and loss of his current situation, and his lament that at that time, traitorous officials were in power and loyal and good people were unwilling. At the time of the full moon, other families gathered together, but they were the only talented people who were for their careers, but they were still unknown and lonely. If you think about it in a different way, how can such a simple five-character poem be famous for centuries and famous for thousands of years? If you are blindly thinking about your family, this poem will not have such a far-reaching impact. ”

The old man said a series of things, and seemed to be a little excited.

The five students in the class listened to the old man's words and were all thoughtful. The perception of the bad old man in front of him has also changed.
