Wang Bo said, pushing the questions over, these are a few physics competition questions assigned by the physics teacher yesterday.

Chen Chu took it and glanced at it,

Topic 1:

Two cylindrical containers with the same cross-section: the right container is H high: the upper end is closed: the upper end of the left container is a piston that slides frictionlessly inside the container......

Chen Chu quickly reviewed the questions, thought for more than ten seconds, and answered the questions quickly.

Solution: Set ......

Write quickly, write out the formula, and the process of solving the problem is smooth.

Wang Bo couldn't take his eyes off the side, and his mouth gradually widened.

Chen Chu finally put down the pen and pushed the question back, "Do you understand?" ”

Wang Bo nodded vigorously!

"Will that be done?"

Wang Bo hesitated and shook his head.

Chen Chu shook his head, took the topic, and explained carefully.

Wang Bo listened carefully, nodded again and again, and a sudden look gradually appeared on his face.

The situation of the two attracted the attention of some people.

Although it is morning self-study, there is no teacher on the podium.

Someone in the front row has been listening, nodding from time to time, listening to it has a feeling of itching through the boots, but it is not enjoyable.

He turned around and sat facing Chen Chu, listening intently.

The people around him gradually gathered some people like him, and they listened attentively.

After finishing a question, Chen Chu asked, "Will you do it now?" ”

Wang Bo nodded vigorously! "It's going to happen!"

There were already four or five people standing next to him, and they also said, "I will too!" ”

"I kind of understood, but there were some places in front of me that I didn't hear and missed it."

After Wang Bo spoke, someone finally couldn't help it, and brought a scroll to cover Wang Bo's title.

"Classmate, I can't do the last physics competition question, can you show it?"

"yes, the last question is too difficult, and I won't do it!"

"I won't, it's too difficult."

"Hey, haven't you always been number one in physics? Neither will you? ”

"It's too hard to ......"

“…… Oh. ”

"What are you? Will you do it? Oh oh oh! ”

Chen Chu picked up this copied test paper with rough layout, looked at it, and reviewed the questions.

Chen Chu fumbled with his hand while looking at it, "Hey, where is my pen?" ”

Someone hurriedly handed over a pen, "Classmates, classmates, use mine, gold pen, easy to use." ”

Chen Chu glanced at it and wrote a few words on the scratch paper, yes, smooth and smooth, and the metal nib felt a little 'soft' to use.

"Thank you." , Chen Chu thanked him.

Then solve the problem on paper, and explain while solving the problem.

The people around me listened attentively, and the self-study was over early if they were not paying attention.

…

At the end of the morning self-study, the math teacher arrived at the classroom ten minutes early.

When I came to the door of the classroom, I was shocked.

Because Chen Chu was standing on the podium, the blackboard was densely packed with formulas and steps.

At this time, Chen Chu was talking about a math problem.

The math teacher slowed his steps, made a shushing gesture to some of his classmates who noticed him, and sat down in the empty seats under the stage, watching quietly.

The teacher looked at the formulas and solution ideas on the blackboard, and gradually opened his mouth wide......

The idea that I never imagined, the way to solve the problem with the sword, ah, this, this...... What a ghost.

“…… Key Messages...... Make a list of the formulas...... Substitution......

Do you understand? Chen Chu turned around, dropped the chalk, and supported the podium with both hands.

"Understood!"

"Understood."

"Well, I don't understand."

Chen Chu scratched his chin and picked up the chalk again, "Okay, let's talk about it again." ”

"Students who understand, I will write a question of the same type, you can do it to deepen your impression."

Chen Chu didn't notice that there was someone sitting in his new seat, so he glanced over and basically didn't know him.

They were all new faces, and a teacher had come in, and he hadn't noticed.

Chen Chu picked up the chalk and wrote a question on the blackboard.

Then, move on.

The class bell rang suddenly!

Chen Chu dropped the chalk, picked up the blackboard eraser and quickly wiped the blackboard clean.

The math teacher in the audience was too late to stop it, and he had already wiped some.

"Chen Chu! Wait a minute! He hurriedly spoke.

Chen Chu was taken aback, this is obviously not the voice of the student, is it the teacher?

Chen Chu glanced at the door of the classroom, no one?

The classroom burst into laughter, and all the students laughed.

Someone reminded, "Chen Chu, the teacher is in your seat!" ”

Chen Chu looked for his seat and found his new teacher in his new seat.

If he hadn't had a good memory, he might have forgotten his new seat.

Chen Chu smiled awkwardly, "Hello teacher!" Come, the location is back for you! ”

This teacher was known to Chen Chu.

He was also present last week when the college entrance examination papers were being done in the office of the head of the school office, and he was still the teacher in charge of marking the math papers.

The math teacher stood up and waved his hand, "You keep talking, it's good." ”

Chen Chu was stunned for a moment, "Teacher, but I'm a student?"

It's not appropriate, right? ”

Teacher, this is your job!

The math teacher waved his hand, "If there is anything inappropriate, you can tell me, and if there is anything wrong, I will correct it." ”

Chen Chu's mouth opened, and in the end he could only say, "Okay......"

He turned around and wiped the blackboard clean and moved on to the next question.

At first, the math teacher looked very seriously, thinking that he could correct Chen Chu's mistakes.

But the more he looked at it later, the more he doubted himself, and there was not a single mistake in the topic that Chen Chu said.

And the way to solve the problem is easy to use, the idea is novel and ingenious, although the idea is a little unexpected, but it is very easy to use.

Well, very, very easy to use.

This can be seen by looking at the expressions of those students who suddenly realized.

In the past, when he lectured on the topic, these students were not so receptive to new knowledge.

The math teacher gradually became ignorant and began to doubt his teaching ability.

Isn't your own teaching method as good as that of a student?

No, it's not just a gap in teaching methods, but also a gap in the way problems are solved.

The math teacher silently bowed his head and wrote down Chen Chu's way of solving the problem on his lesson plan.

Copy it up, copy it up, if you can't use it this time, you will definitely be able to use it next time!

This way of solving the problem is so easy to use!

～

Finally got out of class, and Chen Chu's throat was a little hoarse.

He had been hinting at the new math teacher with his eyes, hoping that he would grasp his high expectations and give him his megaphone.

Unfortunately, the math teacher didn't understand his eager gaze at all.

He thought that Chen Chu was asking him about the right or wrong of his topic!

Nodding his head all the time, yes, you're right, great!

Chen Chu: "......"

What are you nodding, give me the megaphone, my voice is hoarse.

In the end, the math teacher didn't understand Chen Chu's meaning after all, and gave him the megaphone.

But Chen Chu didn't need it anymore because class was over.

Chen Chu immediately put down the chalk, and in the puzzled eyes of the math teacher, he trotted in front of him, and picked up the water cup on his table.

Spring water, quench your thirst.

Chen Chu, who drank the cow, suddenly made the math teacher understand something.

Feeling a little guilty, he patted Chen Chu on the shoulder and walked quickly.

Chen Chu sighed, fortunately, the effect of the spring water was very strong, and the hoarseness of his voice was all healed.

～

Time flies.

In the next two days, Chen Chu did all about learning and learning (touching the fish).

The most devastating thing is that there are no weekends in the third year of high school......

Yes, there are no weekends in the third year of high school, and there is still a month before the college entrance examination.

The entire senior year of high school was sprinting wildly.
