Hearing Xu You's question, Hu Zheng came back to his senses.
"Well... don't rub it yet, continue writing later."
Now that Xu You has written so much, Hu Zheng also wants to temporarily change the teaching method.
Why don't you let Xu You explain this question.
"Everyone stop writing first, and look up at the blackboard. Xu You, just tell everyone about your process."
Hu Zheng simply sat in Xu You's place and vacated the podium for Xu You.
It can not only exercise the students, but also take a rest, which can be regarded as killing two birds with one stone.
It was also rare for everyone to encounter such a scene, and they all raised their heads and looked at Xu You with a smile.
After getting along with Xu You for so long, everyone basically no longer regards Xu You as a competitor.
For a person who is far stronger than himself, he can only look up and pay his respects.
Xu You didn't have any experience in giving lectures on the podium, so he had no choice but to bite the bullet and start explaining.
"For the focal point p, the distance difference between the fixed points po and pm is one-half wavelength. Let the distance from p to the center of the small hole be r0. According to the half-wave band method..."
When Xu You talked about the topic, he didn't have the teaching skills of a professional teacher.
Not only did he fail to make eye contact with the students, but he even accidentally blocked the content on the blackboard when his back was facing the students.
But it doesn't affect everyone's ability to understand Xu You's thoughts.
In this level of classroom, professional ability is far more important than teaching skills.
"It sounds like there is no problem, and it should be the correct answer."
"These steps are indeed wrong in my analysis. The p0' point is actually not a cancellation point, but a strengthening point."
"Did Xu You do this question before? It's done too smoothly."
After finishing the previous part, Xu You was finally able to erase the previous part and complete the last part of the process.
After finishing the whole question, Xu You looked at Hu Zheng who was under the podium.
"Well, Xu You, you did a good job, and you can get full marks. But in the future, I will try my best to calculate. Although I did it right this time, I may not be able to see it with my eyes next time." Hu Zheng also knew that this time, I really have nothing to say to Xu You.
Just a few days ago, Hu Zheng also said that no one present here has the ability to enter the National Conference.
If possible, Hu Zheng really wanted to take this sentence back.
But in front of the students, Hu Zheng couldn't lose face, and insisted on giving Xu You advice in the tone of a teacher.
"Well, teacher, I see."
Xu You walked down the ladder, which was considered to have given Hu Zheng enough face and did not embarrass Hu Zheng.
The students saw it and didn't say anything.
In my heart, I couldn't restrain myself from discussing this matter with my companions.
After class, seeing that Hu Zheng was still in the classroom, everyone didn't dare to speak loudly.
Instead, he took out his mobile phone and started a group in the "Ningjiang Wujing Squad".
[Huang Qingzhong: You God is awesome! Teacher Hu made me speechless. If you do this a few more times, Youshen will replace Mr. Hu]
[Wei Lan: Who would have imagined that within a few days of the training camp, the team members would start giving lectures to the coach. Do you think Mr. Hu can solve this problem without writing? ]
[Dong Ming: You God, have you done this question before? Say you did it, let us feel better]
[Hu Shucheng: I guarantee with my vast experience in brushing questions that this question is definitely a new question. Hey, there is really no comparison between people.]
[Qu Tianxu: What nonsense, Xu You is a god, and we are human beings. How can man compare with God? ]
Xu You felt the constant vibration of his mobile phone and started to check the news.
After finding out that it was a bunch of meaningless flooding news, Xu You was a little disappointed.
I wanted to learn something from this group.
It turned out to be good, and it was all pointless flattery.
When the group was first established, everyone could really discuss and study in the group.
But within a few days, the atmosphere in the group gradually changed.
It's obviously a study group, but apart from study, they can talk about almost everything.
Disappointed, Xu You opened the group message settings and clicked the "Do Not Disturb Messages" button.
In an instant, the phone finally quieted down.
"Xu You, why don't you express your thoughts?"
Seeing that Xu You didn't speak, Hu Shucheng asked jokingly.
"What are you talking about? Let's discuss who in the class has the highest 3-methyl content in the gut?"
Hu Shucheng waved his hands quickly when he heard the words.
"No, no, no, study is the most important thing."
...
A few days later, the provincial team trials for the Ningjiang Provincial Mathematical Competition will begin.
Xu You applied to Hu Zheng for half a day off to take the exam.
In fact, Hu Zheng refused at first.
After all, at this time, the focus should be on things.
But I heard that Xu You's mathematics competition also got the eighth place in the provincial one.
Hu Zheng really had no reason to refuse.
Hu Zheng also knows that there will indeed be a very small number of children who have the strength to enter the national training team in both physical and mathematical competitions.
I can't kill a child's precious opportunity just because of a little self-interest.
The location of the math competition is located in the Math Academy of Ningjiang University.
The distance between Ningjiang University and Shengcheng University is not too far. After Xu Youda got up in the morning, he took a taxi directly to go there.
Xu You is fairly familiar with Ningjiang University.
Because Xu You's father, Xu Zhou, worked at Ningjiang University.
When he was young, Xu You would often come to Ningjiang University to play, or to Xuzhou's laboratory.
"Shuyuan 403... found."
Coming to the door of the classroom, Xu You explained his purpose and showed his ID card.
Amidst the surprised eyes, Xu You found his seat and sat down.
Everyone had never seen Xu You before, and was a little surprised by Xu You's sudden appearance.
How could there be a student who didn't even participate in the training camp and came directly to take the selection test?
But at this time, no one dared to ask this question.
The teachers in charge of the math competition knew a little about Xu You's situation.
"This is the kid who got eighth in the provincial first exam and hasn't participated in the training camp yet?"
"Yes, it's him, Xu You. He is the first in the province's physical competition and the eighth in the mathematics competition. This kid is really not easy. "
I heard that Mathematics is just his sub-item. He didn't study much, so he took the eighth place in the province. If he studies Mathematics with all his strength, is it okay?" "I guess he should have no problem getting into the provincial team." .Fortunately, the time for the national finals of Mathematics and Wujing is staggered, and when he finishes the national finals of Wujing, he should be able to go all out for the national competition."
At 8 o'clock, the selection test officially began.
Like Wujing, the provincial team selection examination of Ningjiang Provincial Mathematical Competition also adopts the standards and difficulty of the national finals.
However, in the normal math competition, there will be two days of exams, with Math 1 and Math 2 respectively.
In order to save time, this trial only takes one subject of mathematics.
It can be regarded as slightly reducing the difficulty of investigation.
Although there are 4 and a half hours of answering time.
But the whole set of test papers only had three questions.
You can imagine how difficult each of these questions will be.
"Fortunately, I hugged the Buddha's feet temporarily last night, otherwise I'm afraid I wouldn't be able to solve a real question."
Xu You couldn't help but feel a little scared after browsing the questions roughly.
