Chen Zhou's words stunned Wang Xuehui.

I thought this was a very thoughtful student, but I didn't expect the idea to be so distinct, no, with a distinct personality.

Wang Xuehui didn't know what to say for a while, it was the first time he had been teaching for so many years.

"Teacher, is there anything else?" Chen Zhou planned to go back to the classroom to study on his own.

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

Seeing this, Chen Zhou did not stay any longer.

When Chen Zhou walked to the door of the office, Wang Xuehui's voice came: "Chen Zhou, the teacher agrees with your point of view, and 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 who was sitting behind a neat desk with a meticulous hairstyle, and said softly, "Thank you, teacher." ”

By the time Chen Zhou returned to the classroom, the first period of evening self-study had already passed halfway.

Physics teacher Wang Chengkang was passionately explaining Newton's first law on the podium, and Chen Zhou shouted three reports before he heard it.

"Come back to your seat, I'm talking energetically. Wang Chengkang waved his hand quickly, signaling Chen Zhou to come in quickly.

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

"Don't laugh, let's move on. ”

Wang Chengkang stopped the commotion in the class, and planned to continue the passionate explanation just now, but after a pause, he said, "Where did I just go?"

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 mentioned that Newton's first law applies to any object, whether it is solid, liquid, or gas. Xu Hongliang, the representative of the physics class, got up and answered Wang Chengkang's question.

"Oh yes, let's move on. Wang Chengkang turned around and took chalk and wrote on the blackboard: Force is the reason for changing the motion of an object, and force is not the reason for maintaining the motion of an object.

This sentence is also an understanding of Newton's first law. It's like a still pebble, if you kick it, it will fly. Hey, the stone changes from rest to motion. As for the second half of the sentence, it involves the inertia of the first law, that is..."

In Chen Zhou's view, physics teacher Wang Chengkang is a very interesting teacher, he can be passionate on the podium, and he can also show an embarrassed face because he forgets words, but he will not be angry with students, which has become his way of enlivening the classroom atmosphere.

Using easy-to-understand language to explain the refined theorem clearly, Chen Zhou admired it very much.

This is probably the charm of the teacher.

In the remaining 30 minutes of the first evening self-study, Chen Zhou heard the bell after class before he could experience enough.

I was a little reluctant to say to Mr. Wang Chengkang in my heart: "Goodbye, teacher." ”

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

"You Teacher Wu are not feeling well, so you will adjust it with me for self-study this evening, so you can study on your own. After Wang Xuehui finished speaking, he pulled the chair and sat on the podium.

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

But he couldn't disobey the will of the head teacher Wang Xuehui, so he had to put away the English exercise book and take out the math handouts.

Evening self-study in natural sciences such as mathematics and science is not only busy for students, but also for teachers.

It's the time of day when the teacher asks questions.

Chen Zhou also encountered a problem that he couldn't know.

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

Wang Xuehui took the review materials handed over by Chen Zhou, but he didn't rush to read the questions, but looked at Chen Zhou and whispered: "The teacher supports your idea and told them, but their language group and school magazine editors are still arguing, and I'm not sure if it can be done." ”

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

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

The stem is: let the focus of the parabola C:X²=2py(p>0) be F, the alignment is l, A∈C, and it is known that the circle F with F as the center and FA as the radius intersects at two points B and D.

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

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

Wang Xuehui thought for a while, first checked the process of solving on scratch paper, and then went back to explain to Chen Zhou: "This question is actually related to two small questions, and they are both solved according to symmetry. Chen Zhou, you see, from symmetry, we can set A as (X0, X0²/2p), where X0>0, then F..."

"And then from A, B with respect to the point F symmetry, 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 the straight line m and the straight line n and the parabola C, do you understand?"

Chen Zhou took the scratch paper and read it again along the problem-solving process before nodding.

Seeing this, Wang Xuehui said again: "You see how interesting this mathematics is, the set of functions and vectors, which is not much more interesting than that language?

Wang Xuehui didn't finish speaking, took out the vibrating mobile phone and looked at it, and immediately got up and walked outside the classroom to answer the phone.

Chen Zhou waited for a while, and saw that Wang Xuehui was still on the phone, so he packed up the materials and scratch paper, returned to his seat and continued to brush the questions.

What he didn't know was that after Wang Xuehui answered the phone, he didn't even have time to go back to the classroom to pack his things, so he rushed to the conference room.

"This kind of student has already come to repeat, so he should study in peace, how can he still talk about love in his composition?"

"I think the essay should still look at the essay itself, not with colored glasses. ”

"I think it's right, the student just writes about love in his essay, didn't Mr. Wang also talk to the student, he didn't fall in love. It can be seen that this essay only represents his opinion on love. ”

"What's the opinion? Nathanli, the first beauty in Moscow? I think he's talking nonsense. ”

......

Wang Xuehui heard the sound of quarreling 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 his glasses back on, and saw this old-fashioned man who was called by a phone call from himself.

Li Dabiao said directly: "There is still a quarrel inside, Chen Zhou from your class has given them an excuse." ”

Wang Xuehui glanced at the conference room and said, "Just quarrel, there will be a result." It's best to be able to get a result out of our argument. ”

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

"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 make the noise.

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

Not long after, footsteps rang out.

Wang Xuehui looked at the direction of the footsteps puzzled, who else could be here?

The footsteps came from far and near, and when Wang Xuehui saw the person coming clearly, 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 go talk to them. Rest assured, this essay can be published in the school magazine. ”

After Principal Zhu finished speaking, he took one person with him to cross Wang Xuehui and Li Dabiao and enter the conference room.
