Xueba starts with change

Chapter 23 This essay can be published in the school journal

Chen Zhou's remarks stunned Wang Xuehui.

I thought this was a very thoughtful student, but I didn't expect such a clear idea, no, with a distinct personality.

Wang Xuehui didn't know what to say for a while. It was the first time he had taught for so many years.

"Teacher, is there anything else?" Chen Zhou planned to go back to the classroom for self-study.

Wang Xuehui looked at Chen Zhou and wanted to say something, but he didn't say it. He waved his hand and motioned Chen Zhou to go back to his self-study first.

Seeing this, Chen Zhou no longer stopped.

When Chen Zhou walked to the door of the office, Wang Xuehui's voice came over: "Chen Zhou, the teacher agrees with your point of view, I will go to help you fight for it, but I can't guarantee it."

Chen Zhou turned around, looked at the old-fashioned teacher with meticulous hairstyle sitting behind a neat desk, and said softly, "Thank you, teacher."

When Chen Zhou returned to the classroom, it was halfway through the first period of the evening self-study.

Physics teacher Wang Chengkang was explaining Newton's first law passionately on the podium. Chen Zhou called the report three times before he heard it.

"Go back to your seat, that's what you're saying." Wang Chengkang waved his hands quickly, motioning Chen Zhou to come in quickly.

Under the podium, the students laughed when they heard Teacher Wang's words.

"Don't laugh, let's continue."

Wang Chengkang stopped the noise in the class and planned to continue the passionate explanation just now. After a pause, he said, "Where did I just say?"

There was another burst of laughter.

Wang Chengkang was a little embarrassed, but he didn't get angry, and called the physics class representative.

"Mr. Wang, I just said that Newton's first law applies to any object, whether solid, liquid, or gas." Xu Hongliang, the representative of the physics class, got up and answered Wang Chengkang's question.

"Oh yes, then let's talk about it." Wang Chengkang turned and took chalk and wrote on the blackboard: force is the reason for changing the state of motion of an object, force is not the reason for maintaining the state of motion of an object.

"This sentence is also an understanding of Newton's first law. It's like a static stone. When you kick it, it will fly. Hey, the stone will change from static to moving. As for the second half of the sentence, it involves to the inertia of the first law, that is to say"

In Chen Zhou's opinion, Wang Chengkang, a physics teacher, is a very interesting teacher. He can be passionate on the podium, and he can show embarrassed faces because he forgets his words, but he will not get angry with the students. The way he enlivens the classroom atmosphere.

Chen Zhou was very impressed by explaining the refined theorems clearly in plain language.

This is probably the charm of the teacher.

In the remaining 30 minutes of the first evening self-study, Chen Zhou heard the bell for the end of get out of class before he had experienced enough.

With some reluctance, I said to Teacher Wang Chengkang in my heart: "Goodbye, teacher."

The second part of the evening self-study was in English, but it was not Mr. Wu Mei who appeared, but Wang Xuehui, the head teacher of the class.

"You, Mr. Wu, are not feeling well. You will adjust your self-study session with me this evening. Let's study on your own." After Wang Xuehui finished speaking, he pulled up his chair and sat on the podium.

Many students under the podium were reluctant for a while, they missed the charming Teacher Wu.

However, he could not go against the will of the head teacher Wang Xuehui, so he had to collect the English exercises and take out the mathematics lecture notes.

In the evening self-study of natural sciences such as mathematics and science, not only students are busy, but teachers are also busy.

This is the time of day to catch teachers asking questions.

Chen Zhou also encountered a problem that he did not know.

After thinking for a while, but still having no idea, Chen Zhou got up and walked to the podium to ask for advice.

Wang Xuehui took the review materials handed over by Chen Zhou, and did not rush to read the question, but looked at Chen Zhou and said in a low voice: "The teacher supports your idea and also told them, but their language team and school magazine editor are still there. Noisy, I'm not sure if it will work or not."

"Thank you, teacher." Chen Zhou said sincerely, after all, there are not many head teachers who can be like this for their students.

Wang Xuehui smiled and didn't speak anymore, but looked down at the question asked by Chen Zhou.

The title stem is: Let the focus of the parabola C:X=2py (p>0) be F, the directrix be l, A∈C, it is known that the circle F with F as the center and FA as the radius intersects l at B and D. point.

Then there are two small questions. Question (1) has been solved by Chen Zhou, and question (2) remains.

Question (2) is if three points A, B, and F are on the same straight line m, the straight line n is parallel to m, and n and C have only one common point, find the ratio of the distance from the origin of the coordinates to m, n.

Wang Xuehui thought for a while, first checked the solution process on the scratch paper, and then went back to explain to Chen Zhou: "This question is actually two small questions that are related, and they are both solved based on symmetry. You see, from the symmetry, we can set A to be (X0, X0/2p), where X0>0, then F”

"By A and B being symmetrical about point F, we can get."

"So, the ratio of the distance from the coordinate origin to m, n is √3p/2: √3p/6=3. The main thing is how to use symmetry to find the tangent point of straight line m and straight line n and straight line n and parabola C, understand Yet?"

Chen Zhou took the scratch paper, followed the problem-solving process again, and nodded.

Seeing this, Wang Xuehui said again: "Look at how interesting this mathematics is, the set of functions and vector sets, which one is not more interesting than that language? In the future."

Before Wang Xuehui finished speaking, he took out his vibrating mobile phone and looked at it. He immediately got up and walked outside the classroom to answer the phone.

Chen Zhou waited for a while, and seeing that Wang Xuehui was still on the phone, he packed up the materials and scratch paper, and went back to his seat to continue writing questions.

What he didn't know was that after Wang Xuehui answered the phone, he rushed to the conference room before returning to the classroom to pack up.

"This kind of student has already come to repeat the study, so he should study peacefully. How can he still talk about love in the composition?"

"I think the composition should still look at the article itself, instead of wearing colored glasses."

"I think it's also right. The student only wrote about love in the composition. Didn't Mr. Wang also talk to the student? He was not in love. It can be seen that this composition only represents his opinion on love."

"What opinion? Natalie, the most beautiful woman in Moscow? I think he's just joking."

Wang Xuehui heard the quarrel in the conference room when he was far away, and couldn't help frowning: "It seems that Chen Zhou's composition is just a fuse."

When Wang Xuehui approached the conference room, he saw his old partner at the door, who was wiping his black-rimmed glasses.

Li Dabiao heard the footsteps, put on his glasses again, and saw this old-fashioned man who was called by himself.

Li Dabiao said directly: "It's still noisy inside, and Chen Zhou from your class gave them an excuse."

Wang Xuehui glanced at the conference room and said, "Just quarrel, there will always be a result. It is the best to be able to quarrel with us."

"However, what I didn't expect was that you, old-fashioned, actually stood with me this time." Li Dapin thought that Wang Xuehui should be the most old-fashioned person, just like his desk and hairstyle, neat and meticulous, but Unexpectedly, he would support the publication of Chen Zhou's composition in the school journal.

"Chen Zhou is my student." Wang Xuehui said, and was about to push open the door of the conference room and go in to help the noise.

"Don't worry." Li Dabiao grabbed him and motioned him to wait, as no one else arrived.

Not long after, footsteps sounded.

Wang Xuehui looked at the direction of the footsteps in confusion, who else would come here?

The footsteps came from far to near. When Wang Xuehui saw the person coming, he couldn't figure it out anyway, how could he come?

It was none other than Zhu Ming, the current principal of Maochang High School.

"Let's go, I'll talk to them. Don't worry, this essay can be published in the school journal."

After Principal Zhu finished speaking, he took the person following him, passed Wang Xuehui and Li Dabiao, and entered the conference room.
