CHAPTER XVII

The next day, the lecture hall where the competition coaching class is located.

Wearing a plaid shirt and a slightly balding head, Gao Yunjin walked into the classroom.

Looking around, I looked at the full seats and had a satisfied expression on my face.

Gao Yunjin prefers to teach students in this pure campus environment rather than in a competition coaching institution.

Especially when those eyes full of intellectual curiosity look at themselves, it is a kind of comfort from top to bottom.

Haicheng No. 1 Middle School did not hesitate to spend a lot of money to invite itself, and Gao Yunjin understood very well what the school's purpose was.

But Gao Yunjin didn't mind handing over a satisfactory answer sheet to Haicheng No. 1 Middle School.

At the same time, on his resume, once again leave a glamorous stroke!

With more than ten years of tutoring experience, Gao Yunjin will not doubt that he will not be able to achieve the school's goals.

Gao Yunjin put a book of tutoring materials on the lectern from his briefcase and put on a megaphone.

"Okay, students, let's start class. However, before I start the lecture, I would like to apologize to the students. ”

Gao Yunjin's words confused the students.

"Yesterday, due to my negligence, there was a mistake in one of the after-class questions assigned to you. The problem of solving the 'least dividing edge' was an IMO question from last year, but I accidentally sandwiched it into the assignment I gave you. Gao Yunjin explained,

"I'm sorry for that. The difficulty coefficient of that question is too high, and it is impossible to get such a difficult question in the math league. So, everybody, just ignore that question. When you're in college, you might want to try to solve that problem. ”

"But, teacher, I seem to have solved the problem you said. Just as Gao Yunjin opened the tutorial book and was about to start lecturing, a voice sounded very abruptly in the classroom.

Looking in the direction from which the voice came, Gao Yunjin saw Bi Qi and his raised arm.

Gao Yunjin clearly remembered that this classmate's name was Bi Qi, because in a recent quiz, Bi Qi was one of the most eye-catching performers, close to the level of the first province.

"Bi Qi, what you said is true, you really solved that problem?"

Gao Yunjin's tone was filled with deep surprise, because in his opinion, with the difficulty of that question, it was normal for no one in the entire tutorial class to answer it.

And with Biqi approaching the level of the provincial line, it should be that he has no ability to challenge the IMO test questions at all.

This is the eyes of more than 100 people in the lecture hall, all focused on Bi Qi who was sitting in the front row.

It's not the first time, Bizzie knows what to do on such an occasion.

Bizzie smiled confidently, "That's nature. ”

Gao Yunjin's eyes lit up, could it be that in his hands, another mathematical genius was going to rise, "Then Bi Qi, hurry up and write your solution process on the blackboard." ”

Gao Yunjin's tone already carried a little urging in it.

Under the gaze of the audience, Bi Qi got up, walked to the podium as if no one was around, and skillfully picked up a piece of chalk.

First of all, divide the graph paper into three areas according to the figure, dyed in three colors, and the thick lines are all separating edges, and there are a total of 56 separating edges at this time. For the purposes of L≥56, the lines of the graph paper are written as A1, A2, A3 from top to bottom, ......]

Five minutes later, Bizzie stopped writing.

The blackboard is already full of formulas.

Bi Qi turned around, looked at Gao Yunjin on the side of the podium, and said with a light smile, "Teacher, is my answer correct?"

"That's right, it's completely right!" Gao Yunjin's tone was so excited that he almost couldn't help but stretch out his hand to applaud.

Smooth flow, all in one go!

For Bi Qi's answer steps, Gao Yunjin can only use these eight words to describe it.

Genius, this student is really a genius! even more genius than that!

Gao Yunjin looked at Bi Qi's gaze, as if he was looking at a peerless treasure.

Bi Qi was a little stunned by Gao Yunjin's "coveted" gaze, and subconsciously shuddered.

"Bi Qi, did you come up with this process yourself?" asked Gao Yunjin expectantly.

But Bi Qi gave an answer that made Gao Yunjin extremely disappointed, "I'm sorry, teacher, I actually asked my math teacher for the solution process of this problem." ”

Gao Yunjin's smile instantly froze on his face, "Yours, math teacher?"

"That's right, it's Teacher Gu!" Bi Qi's tone seemed to be showing off something, "I saw with my own eyes that in less than five minutes, Teacher Gu easily solved this problem." ”

"Less than ...... Five minutes?!" Gao Yunjin frowned, his gaze slightly deep.

An IMO question can definitely stump half of high school teachers.

And the other half that can be done is definitely not possible to do it in less than five minutes.

This is far from a level that a high school teacher can achieve.

You must know that even he, a gold medal lecturer who has been immersed in the Olympiad field for more than ten years, spent nearly half an hour doing this question.

In Gao Yunjin's view, this eighty percent is just an exaggerated embellishment made by Bi Qi in order to advocate his teacher.

Gao Yunjin, who was in a fluctuating mood, didn't bother to dwell on this detail.

If it weren't for the student, a high school teacher, who solved the problem, then there wouldn't be too much of a surprise.

"Bi Qi, go back. We officially started the class. ”

An hour later, the competition coaching session ended.

Physically and mentally exhausted students are stepping out of the classroom.

Gao Yunjin was packing up the lesson plan on the lectern, and the teaching director walked in against the flow of people at this time.

"Teacher Gao, how is the performance of the students, didn't make you embarrassed, did you?"

Gao Yunjin also saw the teaching director, and he shook his head, "No, no. The students are doing very well and give me a small surprise from time to time. ”

"That's right. Teacher Nagao, the students' competition ......" the dean asked the purpose of the trip.

"Director Ma, let's talk as we go. Gao Yunjin picked up his briefcase and made a gesture of invitation to the dean, "The situation is much more optimistic than I thought. I can guarantee that the number of people who can enter the provincial front line this time is at least two. ”

The dean's face was relieved.

"But Director Ma, if you can approve the plan I mentioned earlier, I am sure to double this number. Gao Yunjin continued.

"Spend half of the week's math class on competition coaching, Mr. Gao, you also know that this plan will not be agreed to at all. The dean smiled wryly.

"I don't need half of my math class every week, I just don't have a math class for a while. Gao Yunjin held up a finger.

"This ......" Dean Dean looked hesitant, as if he was really thinking about the feasibility of this plan.

"Teacher Gu!"

Behind him, there was a voice of surprise, and then Gao Yunjin entered the class and walked quickly towards a young man.

The young man looked up, just in time to meet Gao Yunjin's gaze.

"Teacher Gao, long time no see. Gu Lu smiled.

"Gu ...... Gu Lu, why are you here!" Gao Yunjin's heart stirred up.
