Seeing that everyone's faces were very weird, Guo Zhuocheng said again: "Let's use ten minutes to make a simple game now, and I will make everyone believe that my mathematical knowledge is very good." Now, you sue me, which of you has the best math score? Please do your best to come up with as many math problems as you can for me, whether it's in the book or whatever you think of yourself. If I don't finish a question for more than three minutes, I'm lost. Who's coming? ”

Everyone, you, me, you, all have disbelief in their eyes. After a while, everyone scrambled to nominate the person they thought was good at math∽ The girl squirmed for a while, and then she opened a book and read it out of a question that she couldn't do.

She was reading a solid geometry, which is the maximum radius of an inscribed circle in a polyhedron. Because it involved graphics, she couldn't describe the graphics clearly for a while, so Guo Zhuocheng had to walk over, glanced at it a few times, and then walked to the blackboard and drew the figure with her bare hands, adding an auxiliary line casually.

He said: "The answer to this problem is that 4.5 ♀ is a relatively ordinary problem of finding the extreme value of a quadratic function☆ The key is how to make auxiliary lines and how to establish this mathematical expression. Both smart people and ordinary people will draw this auxiliary line as I do now. However, if you don't have a full imagination, this auxiliary line will not help you much, but will lead you to a dead end, and you will have to spend a lot of time proving that the line below is equal to the line on the right.

However, the conditions to prove their equivalence are far from sufficient. What to do? The smartest people, like me, will make another auxiliary line perpendicular to it, through the vertex of guò. Did you find anything in this right-angled plane? Forty-five degree angles, students, what does it mean that there is an acute angle in a right triangle that is forty-five degrees? This means that the two right-angled sides are equal! ”

The girl who asked the question had starry eyes and said distractedly, "Wow, do that? Why didn't I think of that? ”

Because she has been tortured by this question for a long time, she is naturally the first to react. Although the other students did not fully understand Guo Zhuocheng's words, after listening to her exclamation, they knew that Guo Zhuocheng was right this time: My God, I came up with an idea after a few glances, and I calculated the answer, which is really good.

Guo Zhuocheng was not proud of this, he only felt that these young students were very pitiful, and they had been delayed for so many years of study, "When he was in high school, this kind of topic could only be regarded as an ordinary topic, and it was impossible to climb the hall of elegance as a difficult problem for teachers."

He said: "Actually, the person who came up with this question is playing this little clever, can you think of this auxiliary line?" If he learns that you are surprised now, he will be secretly happy. ”

"Hehe......" all the students laughed.

Guo Shucheng asked again: "If there is anyone who has a problem that he can't do, let's give another one." ”

One of the students raised his hand and said, "Old ......, I don't know how to do analytic geometry here." ”

Guo Zhuocheng smiled: "It's very easy, if you do a question, you will recognize half of it, and the 'teacher' will shout out an 'old' word, if I make this question, you will really call me 'teacher'." By the way, my surname is Guo, and my name is Guo Zhuocheng, so that you don't know how to shout later. Or do you have to do a question to shout the word 'Mr. Guo', right? ”

Everyone burst into laughter, and one student shouted, "I'll call you Teacher Guo now." Hello, Mr. Guo. I love listening to your lessons! ”

Guo Shucheng smiled: "Calm down, calm down first, what if the question I did just now happened to be done yesterday?" Then you've been deceived by me. After completing this question, it's not too late to take refuge when you think clearly. ”

"Haha...... interesting!"

"Hehe...... this kind of teacher is good."

"Hee-hee...... this little teacher is so interesting."

Guo Zhuocheng walked over the problem for a few moments, then walked to the blackboard, drew the figure first, and said: "The answer to this question is: the orbit of point p is a spherical ♀ surface with a radius of one-half r at the center of the circle of point a, and the difficulty of the problem is the translation of the coordinates and the setting of the analytical equation of the parabola. ”

Then, he explained the solution ideas and calculated the relevant equations step by step on the blackboard.

The simple explanation, the witty language style, and the speed of solving the problem made the students drunk one by one, and everyone listened very carefully.

After finishing the difficult problems raised by the four students, the students basically recognized Guo Zhuocheng's status as a teacher, although they still felt a little strange in their hearts.

Next, Guo Zhuocheng officially began to teach trigonometric functions, except for his lecture, none of the students spoke small. When he stopped, the classroom was silent, startling the teachers who passed by, and they all looked in through the bowls in the windows.

They just can't overlap a teenager with a high school teacher; It is impossible to overlap the person who just threw a student out, but now is serious about teaching; It is not possible to think of students who used to be in class and are now listening very carefully as people in the same class.

Only Principal Shu, who had been worried about this, sighed softly and said in his heart: "Everything about this kid is unexpected." ”

His gaze was a little worried towards the school gate. There, the student who was thrown out by Guo Shucheng was whispering something to a few people, and there was a young man in the group who made him extremely annoyed - Yin Gui: "What bad things are these guys thinking?" ”

The answer was soon revealed.

As soon as the bell rang for the end of class, those guys rushed over and stopped at the door of the classroom.

Principal Shu hurriedly stopped them and asked, "What are you going to do?" This is the school, you have to get out right away! ”

A shirtless young man grabbed Principal Shu to the side and said, "Get out!" It's none of your business here, we're looking for that little turtle cub. Lao Tzu has endured it for a long time, if you don't leave, don't blame us for being polite! ”

Where did Principal Shu dare to leave, he still stopped and shouted to his nephew: "Yin Gui, you go back to Lao Tzu!" ”

Yin Gui was a little weak-hearted, but he still stubbornly said: "He offended us, we can't just leave, right?" ”

Principal Shu said angrily: "Why did he offend you? You...... Don't you know who he is? I tell you, if you dare to touch a single hair of him, I will tell you not to eat and walk around! Get back! ”

The shirtless young man sneered: "Isn't it the son of the secretary of the county party committee?" Which onion is he? Principal Shu, I tell you good news, Guo Zhiyan is stepping down! He won't be able to jump for a few days, if you don't want to go to jail, draw a line with him right away! ”

Principal Shu, like the others, stared at the bare-chested young man with disbelief, his eyes flickering uncertainly.

The shirtless young man said proudly, "You really don't know yet? His affairs are all in the "Yigong Daily". The first is to sympathize with the cover-ups and use the state's money to curry favor with the rightists. Second, he encouraged the peasants to engage in the 'three self and one package' and the 'four freedoms' in an attempt to restore the road. Tell me, how could he have such a big guts? Isn't it because someone helped him and supported him? And are you stinky nine the ones who support him? You guys are so good to his pups, you must have received some benefit from the surname Guo, right? ”

Several older teachers were so frightened that their faces turned white, and they were so frightened that they retreated one by one→ for fear that others would think that he and Guo Zhiyan were people in the same trench, for fear of being dragged out to fight in the streets.

"What bullshit are you putting here! My dad is sympathetic to the rightists, and he wants to eliminate the peasants to keep more land for themselves, did he make a mistake? What level of organization is it forbidden? Guo Zhuocheng happened to come out of the classroom and asked loudly.

The shirtless young man was overjoyed and hurriedly asked: "Boy, your father sued you that he sympathized with the rightists and that he supported the peasants in dividing the land?" ”

Guo Zhuocheng knew that this guy wanted to grasp the handle in his words, and he was naturally happy to pass these "handles" to the other party through the mouths of these guys, so he pretended to be a child and said: "Yes, I have heard my father say many times at home that the rightist comrades are very pitiful and wronged, and we should help them more, although our country is in difficulty now, but no matter how difficult it is, they can't be bitter There is nothing wrong with the people dividing the fields, so that they can order a variety of dishes and a variety of cash crops, which is also a good thing." Could it be that my dad did not do these things right? ”

The shirtless man and the student who was thrown out of the classroom by Guo Zhuocheng glanced at each other, and their eyes were full of surprise.

The bare arm hurriedly said, "Yes, yes, no...... I mean, you're right, you tell your father about it, it shows that you are a good classmate with a high level of consciousness. By the way, what else did your dad say? ”

Principal Shu next to him was anxious, and hurriedly said, "Okay, okay, everyone disperse, let's go to class later." ”

The shirtless man glared at Principal Shu and said, "The surname is Shu, you don't want to live, do you?" You are not worthy of being a people's teacher, not only sympathize with the rightists, but also dislike the poor and love the rich, and say that a good son-in-law will not want it if he says he doesn't want it. Get lost! ”

Principal Shu had been criticized by students before, and now he still has palpitations when he thinks about it, and he wants to speak for Guo Zhuocheng again, but he doesn't dare to say it, and he said in his heart: Guo Zhuocheng, this kid used to be so smart and so clever, how did he become so stupid today? Knowing that people are here to grab the handle and find faults, how can you follow their words and say what your father said privately at home? Didn't you hurt your father?

Guo Zhuocheng seemed to be really stupid, and said: "My dad said a lot. ”

The bare shoulders pretended to be kind, and asked with a smile, "For example?" The excited gaze showed how eager and excited he was: the handle, so easy to get hold of.
