In the morning, Ren Xiaosu was reading in the library, while An Yuqian was sitting at the door of the library, leaning on a chair and falling asleep.
If the sun shines on An Yuqian's face from outside the door, An Yuqian will put a book on his face to block the light.
Every morning when Ren Xiaosu came, he would consciously give An Yuqian ten yuan, and An Yuqian didn't need to call Ren Xiaosu to remind him. He always yawned and waited at the door at 8:30 every morning.
Gradually, An Yuqian felt uncomfortable being like this. He used to play mahjong all night and then take a good sleep at home in the morning.
After the person named Ren Xiaosu came, he could only sleep on a chair in the library!
Is it possible to sleep in a chair as comfortably as in a bed?
While there was no one in the library, An Yuqian made a point of observing what book Ren Xiaosu was reading. He almost died from laughter. It turned out to be the first-year high school mathematics, physics, and chemistry textbooks!
Ren Xiaosu persisted in coming to the library for so many days, which finally made An Yuqian look at him with admiration. An Yuqian thought that there was finally a studious person in the library, but what he saw was the textbook for the first year of high school. .
Looking at Ren Xiaosu’s age, he must be in his senior year of high school, right? Co-author is a poor student who started tutoring from scratch?
An Yuqian counted on his fingers and found that there were only three months left before the college entrance examination. Is it too late to tutor for the first year of high school?
Although An Yuqian was strolling beside him, Ren Xiaosu didn't even raise his head to look at him.
An Yuqian couldn't help it anymore: "It's a little late for you to make up classes now, the college entrance examination is only three months away!"
Ren Xiaosu raised his head and looked at him: "I will not take the college entrance examination. "
"If you don't take the college entrance examination, then why are you studying high school mathematics and physics?" An Yuqian was shocked: "You will go to the factory after graduation. What's the use of learning this stuff?"
< p> "Every knowledge is useful, and the knowledge you learn belongs to you," Ren Xiaosu said calmly.An Yuqian shrugged his shoulders and turned away: "Don't forget to do it before breakfast every day. If it weren't for you, I wouldn't have had breakfast at all. This extra expense is because of you..."
"I know," Ren Xiaosu said.
However, An Yuqian suddenly discovered that besides Ren Xiaosu, there were actually a group of students who suddenly came to read books in the afternoon.
There were more than twenty male and female classmates in total, and they sat in the library all afternoon, for several days.
You must know that although there were people reading books in the afternoon in the past, they were not so frequent and stable, and the number was not so neat. This group of students... were actually sitting next to Ren Xiaosu in an organized and disciplined manner.
After An Yuqian woke up in the afternoon and took a closer look, he found that Wang Yuchi and others were reading books related to mechanical manufacturing, which had already exceeded the high school syllabus.
When the library was closing, Wang Yuchi suddenly said to Ren Xiaosu: "Monitor, it's time to close the door and go home?"
An Yuqian immediatelyHe was stunned. This young man who gave him breakfast money every day was actually the monitor of this group of students? Ordinary students learn things beyond the syllabus, but the class monitor teaches himself in the first year of high school?
This is all a mess...
Ren Xiaosu raised his head and glanced at the sky: "You guys go back first, I'll watch for a while."
"Hey, An Yuqian couldn't sit still: "It's time for me to get off work, you know!"
"Here you are 50!" Ren Xiaosu said without raising his head.
An Yuqian was unhappy: "That won't work either. I should go play mahjong. Maybe I can make it back tonight!"
Ren Xiaosu remained silent. Put the book back on the shelf, turn around and leave.
The first thing Ren Xiaosu said when he saw An Yuqian the next morning was: "Have you copied the book?"
"Why are you such a talkative kid?" An Yuqian said He had a toothache: "Is this something you should ask?"
"Then it's a loss," Ren Xiaosu patted An Yu's first ten dollars and said, "Let's go have breakfast."
An Yuqian held ten dollars in his hand and felt insulted...
In the afternoon, when Wang Yuchi and the others came again, An Yuqian suddenly sat across from him. Ren Xiaosu looked up at him in surprise: "Something's wrong ?"
An Yuqian said: "You are mainly studying mechanical manufacturing, but the book you are reading is wrong!"
Ren Xiaosu frowned and glanced at Wang Yuchi and others. The book in a person's hand: "How should I read it?"
Without a teacher's guidance, they can only fumble forward like holding a stone to cross a river, and their progress is extremely slow.
Although Jiang Wu is a teacher, Jiang Wu is a Chinese teacher...
At this time, An Yuqian said: "For 500 yuan, I will tell you what to see!"
As soon as he finished speaking, Ren Xiaosu threw five hundred yuan over. Wang Yuchi whispered from the side: "Squad leader, why do I feel that he is a liar?"
Ren Xiaosu shook his head: "Liars are not I won’t even have money for breakfast.”
An Yuqian almost cursed, implying that he was not even qualified to be a liar!
An Yuqian sneered and said: "If you want to learn mechanics systematically, don't try to imitate others' running before you can walk. You must first learn mathematics and physics!"
Ren Xiaosu He leaned back in his chair and listened silently, while Wang Yuchi and others had already begun to open their notebooks and prepare to take notes.
"I suggest that you first read "Mathematical Analysis" written by Chen Jixiu as an introduction, and then linear algebra is a must, which you have not learned enough in high school courses."
"Don't read "Public Things"," An Yuqian threw a book on the table: "Just read this Feynman lecture notes."
"Practical analysis...forget it, this first No need to look at it."
"As for mathematical physics methods, just look at Wang Dexin. What everyone talks about are basically real variable functions, special functions, mathematical equations and the like, there is no big difference."< /p>
"Retong, you want to see it."
"You should also read about electrodynamics."
An Yuqian kept talking for half an hour. Ren Xiaosu felt that it would take several years to learn this. As a result, An Yuqian was talking about it at this time and said: "This is just the beginning. If you want to really get involved in sophisticated mechanical manufacturing, you are still far away!"
Ren Xiaosu understood, together This guy is just here to show off his quick words...
But Ren Xiaosu also suddenly realized that this An Yuqian was not an ordinary person. Even if he was a liar, he probably wouldn't carry so much just to earn 500 yuan. Things, the key is that no one can teach him to memorize them.
Ren Xiaosu looked at An Yuqian and said, "Come teach them, and I'll pay you 500 per class."
An Yuqian's eyes lit up, but he immediately became reserved: " My time is precious..."
"400."
"Hey, why is it getting less and less!"
"300."
"I teach! 500! Not a penny less!"
Ren Xiaosu then laughed: "If you don't teach well, I won't pay."
"Can I teach you?" An Yuqian's eyes widened: "I, An Yuqian...forget it, even if I tell you, you don't understand!"
It's just that An Yuqian suddenly I feel that the young man in front of me may be more complicated than I imagined. Who among the ordinary students would pay 500 yuan for a class?
