Zhang Bo took the Mobius ring made by Chang Kai in his hand, frowned and remained silent for a long time. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

For the current scene, Mr. Li was also caught off guard.

In fact, at the beginning of Mr. Li's fight, what he thought about was how to protect Chang Kai, if Chang Kai was bullied by Zhang Bo, he would come forward.

But where did he think that Teacher Zhang, who has always been known for his ideological work, would also have a time when he was deflated?

In this way, Mr. Li's position will not be able to continue to favor Chang Kai, so as not to add fuel to Zhang Bo's fire.

After being stunned, he pretended to scold Chang Kai, "Chang Kai, what Teacher Zhang just said is very right." As the saying goes, if you have to cross the same boat for ten years, you and Jiang Jinghao can be lucky enough to be in the same class, isn't this fate? I hope that you will be able to unite your classmates and be friendly and help each other with them in the future. Only in this way will you not be alone on the road of life in the future. ”

Chang Kai immediately stood up and said to Teacher Li sincerely, "Your criticism is right, I will reflect on myself after I go back, and strive to achieve the ...... of 'filial piety to parents and respect teachers, love to help classmates, accept criticism with an open mind, and learn to cooperate and coexist'."

Teacher Li suddenly cried and laughed, "Who asked you to memorize the "Code of Conduct for Middle School Students"? ”

Zhang Bo, who was holding the Mobius ring, didn't know how to step down at first, but it wasn't until she heard that Mr. Li was cheering for her that her face improved.

But when she listened to Chang Kai's formulaic perfunctory teacher Li, she felt that he was completely like a hanger, so she couldn't help but speak again, "Chang Kai, you are indeed a smart child, if you can focus on your studies, you will definitely get good results in the college entrance examination next year......"

Chang Kai immediately turned to Zhang Bo and bowed to her slightly, "Thank you, Teacher Zhang, I promise to study hard and make progress every day!" ”

But I heard her continue, "There are too many nonsense thoughts in your head! Actually, it's not just you, it's all of you kids! You know, the human brain is like a bottle, if you don't get rid of the dross in your brain, how can you put more really useful knowledge into it? ”

"Teacher Zhang, what you said is very right." Chang Kai nodded and bowed to her again.

"Very good, you finally realized your mistake, and I believe that you will be a good student to educate!" Zhang Bo's face finally showed a rare smile, just like Ah Q touched the little nun's face and insulted her fiercely.

For her last sentence, Chang Kai hated and hated it.

Zhang Bo is bullying himself and doesn't know this stalk?

What do you mean by "students who can educate well"?

How similar is this to the argument that "children can be educated well" during the "Wenmei" period?

Since the parents of their children who can be educated well are "sinners" who make "mistakes" and are thrown into the cowshed, what kind of people are the parents of "students who can be educated well"?

And what kind of people are the teachers of the "well-educated students"?

Is Zhang Bo mapping his parents, or is he insulting Teacher Li?

"Insult my friend, it's okay; But insult me, no! ”

Chang Kai glanced at Mr. Li, and after thinking of this sentence, he couldn't help but laugh, and soon complained secretly, "No, the correct way to say it should be like this, - you can scold me, but you can't insult my family!" ”

Teacher Li looked at the smile that flashed on his face, and couldn't help frowning again, "Chang Kai, you ......"

Zhang Bo obviously felt the smile on his face as well, and then her face sank again.

This kid is simply unreasonable!

At this moment, both sides were unreasonable, but the momentum seemed to be still on Zhang Bo's side, so she secretly suppressed her trembling hands and deliberately maintained her demeanor as a division commander.

Chang Kai turned slightly sideways, stared at Zhang Bo's face, and asked slowly, "What did Mr. Zhang mean just now, is it that the volume of each bottle is certain?" ”

Seeing that she couldn't help but nod, Chang Kai turned around again and smiled at Teacher Li, "Teacher Li, you give me another piece of paper and a pen......

He took the paper and pen from the dazed teacher Li, and bent down to scribble on the desk.

The next moment, the bell for the evening reading class rang suddenly, Chang Kai seemed to be in a no-man's land, and only the sound of him painting on the paper was left in the office.

Mr. Li looked at the geometric figures that were gradually taking shape, and he was puzzled.

Zhang Bo didn't know what Chang Kai was doing, but he slowly took out a second cigarette and lit it in a hurry.

A minute later, Chang Kai finally drew a Klein bottle and handed it to Mr. Li, "Mr. Li, look, does this bottle have no fixed volume, or even, no end?" ”

The concept of the Klein bottle, originally proposed by the German mathematician Felix Klein, has a very simple structure - a bottle has a hole at the bottom, which now extends the neck of the bottle and twists into the inside of the bottle, and then connects with the hole at the bottom.

This structure makes the bottle have no distinction between inside and outside, and a fly can fly directly from the inside of the bottle to the outside without passing through the surface.

After Mr. Li changed the angle of the paper handed over by Chang Kai, he saw that it was as he said, so he had to smile bitterly and shake his head, secretly scolding him for being "demonic" in his heart, but he didn't know what kind of comment to make, "This ......"

"Mr. Li, this is called a Klein bottle." Chang Kai explained with a smile, and after taking the paper from his hand, he turned around and walked a few steps and handed it to Zhang Bo, "Teacher Zhang, take a look, does this bottle have no fixed volume?" ”

Zhang Bo took the paper he handed over, only glanced at it, and realized that he had been slapped in the face again.

"Chang Kai, you are simply ...... It's just ......" Her face changed greatly, and after she became angry, she didn't know what words to use to condemn Chang Kai.

At this time, she suddenly had the illusion that she wanted to find a hole to drill into.

Leaving here earlier seems like a good option.

She slowly pressed the paper in her hand on the desk, quickly stood up with her strength, and picked up the folder on the desk casually.

glanced coldly at Chang Kai who was standing in front of her, and she walked out in a hurry, and when she passed by the latter, she even deliberately knocked him into a stumbling one.

It's the rhythm of running away if you don't agree with a word......

How can this work? You have to make it clear before you go, right?

"Teacher Zhang......" Although Chang Kai was deliberately bumped by her, he still couldn't help but reach out to save her.

In the next second, Zhang Bo's footsteps did stop, but Chang Kai had a bad feeling, the whole person was Spartan!

Teacher Li, who was not far away, was also stunned at this time!

At this moment, it seemed that even the air in the office was frozen.

At this moment, it seems that the whole world has become extremely quiet!
