Gu Xu put away his emotions and returned to class with his thoughts.

Zhang Xiaoli drew the question on the paper projected on the screen.

Wang Xianchao took the second exam this time, and his results improved by leaps and bounds, and he must be proud.

This time, it's my own! Careless!

Not next time!

Gu Xu slowed down again and looked at the math problems on the blackboard.

This question is very new, and it is the first time he has seen it.

"Students, this is a question of N-dimensional space. The content is a bit overclass, and the N-dimensional space is not in high school knowledge, and if you go to college, if you study mathematics, you will definitely read it.

If you are admitted to the Department of Mathematics, you will learn a lot about geometry, analytic geometry, differential geometry, advanced geometry......

If you use university knowledge to solve this problem, it will come out quickly, but it is difficult to use high school knowledge.

We're here to compete, and the time to compete is limited.

If you can do more questions in a limited time, you will be the winner.

The winner takes all!

Therefore, the teacher has to talk about some university knowledge today, and everyone must pay attention to it. ”

Gu Xu's heart tightened, this is the cruelty of competition.

Classes are usually fine.

As soon as such a competitive link arrives, the cruelty of reality is highlighted.

I don't know when I started to learn the content of junior high school in elementary school, I started to learn the content of high school in junior high school, and I learned the content of university in high school.

That's how you can beat your competitors.

In other words, the more you learn, the easier your chances of winning.

Gu Xu was thinking about it, but was interrupted by the sighs around him.

"Teacher Zhang, I have even learned university knowledge by participating in the competition!"

"Teacher Zhang, will this question be too difficult, you can change it!"

"Teacher, how many questions are there like this! If you don't have one, you're not talking in vain! ”

"Look at your learning attitude!" Zhang Xiaoli said sharply, "My heart is for your good, let you learn more, you just have this attitude!"

This kind of question, just a teacher like me who graduated from the mathematics department of a regular university has this level to tell you, you still don't cherish it, it's really angry to me!

What do you love if you don't want to hear it! Don't disturb the students who want to listen! ”

For Zhang Xiaoli's words, Gu Xu was very touched in his heart.

In a school, the teaching level of teachers is different, some are good and some are bad.

Once, as he walked through the hallway, he heard a student asking the teacher a question.

What they said, he didn't know.

He saw that the teacher had finished his sentence, and then turned to leave.

As a result, the student in question looked at the teacher's back and complained with resentment, is this teacher too second!

There is no process for the topic, and when I see that the answer is root number 2, I directly write a root number 2 to perfunctory me.

If that's the case, what else do I want you to say!

Gu Xu thought and sneered.

"I start lecturing, I listen to what I want to hear, and I don't force what I don't want to listen!" Zhang Xiaoli continued to lecture.

Zhang Xiaoli has always adhered to the attitude of not forcing in class.

For students who are willing to learn, she will not be upset even if she tells him a hundred times.

And for those who don't want to learn, her attitude has always been, you don't want to learn, and I don't bother to teach.

Gu Xu smiled lightly, Zhang Xiaoli has always been very individual.

He paid attention and listened attentively......

Time flies when anything is put into the state.

In his previous life, Gu Xu always felt confused, even if he mentioned his spirit, his brain was still like paste.

If you get sick, the whole person will be dizzy, and the teacher won't know anything.

In this life, he feels more and more sober.

He can not only understand the content of the teacher's class, but also follow the teacher's train of thought.

After the teacher explained them carefully, these questions were imprinted in my mind like an imprint.

On one question, Zhang Xiaoli gave more than one lecture, and she didn't stop when she got out of class in the middle. If you want to go to the toilet, go to the toilet, and if you don't want to go, go on.

"Okay, this question is finished, does anyone understand?" Zhang Xiaoli looked at the students present, and the students' expressions were quite confused.

Zhang Xiaoli felt that it was difficult before she spoke, and such a question was thankless, but for the sake of the future of the students, she still had to talk about it.

Zhang Xiaoli was a little disappointed: "Let's think about it, discuss it with each other, and ask me if you don't understand." ”

Jia Fanzhen asked Lan Ruosi in a low voice: "Xiao Sisi, do you understand?" ”

Lan Ruosi shook his head: "I don't understand, I feel very 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 an ideal cup or a regular class, Lan Ruosi would ask Gu Xu as soon as he felt that there were difficult topics or knowledge points.

"Understood!" Gu Xu nodded, "The content of the teacher's class today is not difficult, I understand everything." ”

"Isn't it difficult?" Lan Ruosi was stunned for a moment, and her voice rose, "How do I feel difficult!" ”

Gu Xu smiled: "You think it's normal, didn't Teacher Zhang say it?" This question is out of the box! ”

"This question is really out of the syllabus, but I think the knowledge points that Mr. Zhang said were also talked about in high school, mainly because they are extended."

"Yes, the difficulty is how to extend!" Gu Xu said with certainty.

"Look at you like this, you really understand. Tell me about it! Lan Ruosi was puzzled, she really needed someone to talk to her.

Gu Xu said in a joking tone: "Ouch, Xueba also wants to talk to me?" The sun is really coming out in the west. ”

"Nasty!" Lan Ruosi smiled, "I'm not a saint, why can't I have a question!" ”

"Okay, I'll tell you until you understand!"

Gu Xu smiled silently in his heart, it has always been my little daughter-in-law who has given me a lecture, but I didn't expect that I would give her a lecture today.

In fact, it is not difficult to understand that she is only a teenager after all, and she is a person who has lived a lifetime.

There are a lot of topics that you really don't understand at that age. Come back when you're older, maybe you don't need anyone to tell you, and you'll understand.

It's like, when you reach high school, it might be easy to look at the topics in elementary school.

Gu Xu smiled: "Do you need me to explain it all from beginning to end, or if you don't understand something, I'll tell you something." ”

Lan Ruosi was puzzled: "I'm actually very confused, I want to understand, I feel that my thinking is not clear, I can't say that I don't understand, but I can't say that I don't understand." Tell me all about it! ”

"Maybe your thinking is fixed somewhere, you listen to my thinking, my thinking may be better than yours, I'll analyze it for you slowly!"

Wang Xianchao couldn't listen to it anymore, and said coldly: "Pretend!" ”

Gu Xu smiled lightly: "What am I pretending?" ”

"Lan Ruosi didn't understand...... he wanted to say, but I didn't understand either, but when the words came to his mouth, he still swallowed the sentence back and continued, "You are a scumbag, and you still understand, this is not pretending to be anything!" ”

"First of all, I'm not a scumbag! Lan didn't understand, he was humble. You don't understand, that's why you think I don't understand. ”

Wang Xianchao was a little weak-hearted: "Who said I didn't understand, I understood!" ”

Gu Xu immediately asked: "Then when Teacher Zhang asked just now, why didn't you say that you understood!" ”
