Gu Xu put away his emotions and returned his thoughts to class.
Zhang Xiaoli drew a question on the paper projected onto the screen.
Wang Xianchao came second in the exam this time and his grades improved by leaps and bounds. He must be proud of it.
This time, I did it myself! Careless!
Don't do this next time!
Gu Xu calmed down again and looked at the math problems on the blackboard.
This question was very novel and it was the first time he had seen it.
"Students, this is a question about N-dimensional space. The content is a bit out of the ordinary. N-dimensional space is not covered in high school knowledge. If you go to college and major in mathematics, you will definitely learn about it.
If the students here are admitted to the Department of Mathematics, you will learn a lot about geometry, analytic geometry, differential geometry, advanced geometry...
If you use college knowledge to solve this question, it will come out quickly, but it will be difficult to use high school knowledge.
We are competing for a limited time.
The winner is the one you can solve more questions in the limited time.
The winner takes all!
Therefore, the teacher has to talk about some university knowledge today. Everyone must pay attention. "
Gu Xu's heart tightened, this is the cruelty of competition.
Normally classes are fine.
Once it reaches such a stage of competition, the cruelty of reality becomes apparent.
I don’t know since when primary school students began to learn content from junior high school, junior high school students began to learn content from high school, and high school students began to learn content from college.
This is how you can beat your competitors.
In other words, the more you learn, the easier your chances of winning.
Gu Xu was thinking, but was interrupted by the sighs around him.
"Teacher Zhang, I even learned college knowledge by participating in the competition!"
"Teacher Zhang, is this question too difficult? Please try another one!"
"Teacher, how many questions are there that are beyond the syllabus! If you don't even have one, you're talking about it in vain!"
"Look at your attitude towards learning!" Zhang Xiaoli sternly said, "I only do it for your own good and let you learn more, but this is the attitude you have!
This kind of question can only be explained to you by a teacher like me who graduated from the mathematics department of a regular university, but you still don’t cherish it. It really pisses me off!
What do you do if you don’t want to hear what you love! Don’t influence the students who want to hear it! "
Gu Xu felt very touched by Zhang Xiaoli's words.
In a school, the teaching level of teachers is different, some are good and some are bad.
Once, he was passing by the corridor and heard a student asking the teacher a question.
What they said, he didn't know.
He saw that the teacher had finished speaking in two sentences, then turned and left.
As a result, the student who asked the question looked at the teacher's back and complained with resentment, "Is this teacher too stupid?"
There was no process for teaching the topic. When I saw that the answer was square root 2, I just wrote square root 2 to get rid of me.
If this is the case, what else do I want you to say!
Gu Xu thought and sneered.
"I started lecturing. I will listen to those who are willing to listen. I won't force anyone who doesn't want to hear!" Zhang Xiaoli continued to lecture.
Zhang Xiaoli always adheres to a non-forceful attitude in class.
For students who are willing to learn, she will not be upset even if she tells them a hundred times.
As for those who don't want to learn, her attitude has always been, if you don't want to learn, I'm too lazy to teach.
Gu Xu smiled faintly, Zhang Xiaoli has always been very unique.
He concentrated and listened carefully to the lecture...
Time always goes by quickly when you get into anything.
In his previous life, Gu Xu always felt dazed during class. Even if he roused himself, his brain was still like a mush.
If you are sick, you will feel dizzy and have no idea what the teacher is saying.
In this life, he felt more and more awake.
Not only can he understand what the teacher teaches in class, but he can also follow the teacher's thinking.
After the teacher explained it carefully, these questions were imprinted on my mind like a brand.
Zhang Xiaoli lectured on one topic for more than one class, and she didn’t even stop when get out of class was over. If you want to go to the toilet, go, if you don't want to go, keep going.
"Okay, this question is over. Does anyone understand?" Zhang Xiaoli looked at the students present, and the expressions of the students were quite confused.
Zhang Xiaoli felt that it was very difficult before she started speaking. Such questions were thankless, but for the sake of the future of her students, she still had to answer them.
Zhang Xiaoli was a little disappointed: "Let's think about it and discuss it with each other. If you don't understand, ask me again."
Jia Fanzhen asked Lan Ruosi in a low voice: "Xiao Sisi, do you understand?"
Lan Ruosi shook her head: "I don't really understand. I feel confused when it unfolds later."
Lan Ruosi subconsciously looked at Gu Xu: "Gu Xu, do you understand?"
I don’t know when it started. Whether it was the Ideal Cup or regular classes, Lan Ruosi would ask Gu Xu as soon as possible if she found a difficult question or knowledge point.
"I understand!" Gu Xu nodded, "What the teacher taught today is not difficult. I understand everything."
"Isn't it difficult?" Lan Ruosi was stunned for a moment, her voice rising, "Why do I feel it's difficult!"
Gu Xu smiled: "You think it's hard to be normal, didn't Teacher Zhang say that? This question is beyond the syllabus!"
"This question is indeed beyond the outline. However, I think the knowledge points mentioned by Teacher Zhang have also been taught in high school. They are mainly extended."
"Yes, the difficulty lies in how to extend it!" Gu Xu said affirmatively.
"Looking at you like this, you really understand. Please tell me!" Lan Ruosi was confused. She really needed someone to explain to her.
Gu Xu said in a joking tone: "Oh, the top student also wants to ask me for a lecture? The sun really rises to the west."
"I hate it!" Lan Ruosi smiled sweetly, "I'm not a saint, why can't I have questions that I don't know?"
"Okay, okay, I'll tell you until you understand!"
Gu Xu smiled silently in his heart. My daughter-in-law has always given me lectures, but she didn't expect that I would give her lectures today.
In fact, this is not difficult to understand. After all, she is only a teenager, but she has lived a lifetime.
There are many questions that you really just don’t understand at that age. When you grow up and look back, you may understand it yourself without anyone telling you.
Just like when you reach high school, it may be easy to read the questions from elementary school.
Gu Xu smiled: "Do you want me to tell you everything from beginning to end? Or if you don't understand something, I will explain it to you."
Lan Ruosi was puzzled: "I'm actually very confused too. You know, I think I understand. I feel like my thinking is not clear. I don't understand, but I can't tell you why I don't understand. Please explain it all to me!"
"Maybe your thinking is fixed somewhere. Listen to my thinking. My thinking may be better than yours. I will analyze it for you slowly!"
Wang Xianchao couldn't stand listening anymore and said coldly: "Pretend!"
Gu Xu smiled lightly: "What am I pretending to do?"
"Lan Ruosi didn't even understand..." He wanted to say, but I didn't understand either, but when the words came to his lips, he swallowed them back and continued, "You are a scumbag, but you still understand. Oh, this is not pretending!"
"First of all, I'm not a scumbag! Classmate Lan can't understand, it's because he is humble. Did you not understand, that's why you think I don't understand."
Wang Xianchao felt guilty: "Who said I didn't understand? I did!"
Gu Xu immediately asked, "Why didn't you say you understood when Teacher Zhang asked just now?"
