Chapter 9 Broken Horn and Standing Compass

Approaching the end of class, Zhou Duan keenly saw the bodies of several boys about to move.

But the sitting position is still not too deformed.

Everyone is no longer a freshman in high school, and was caught by the teacher on the spot when class was about to end in those years...... The one who caught it is ripe.

At such times, the entrances and exits of the school building must be full of teachers who are ready to catch the students who are charging back to the dormitory.

"Zero, Zero, ......" sounded with a series of vibrato, and it was obvious that everyone was forcibly suppressing a sense of relaxation.

Those who study hard are still immersed in the sea of questions.

Zhou Duan was worried about the bathroom in the bedroom, but when he saw Yang Xuan's turned body and some red eyes, he still sat down very honestly.

Of course, it's not because the other party is pretty...... It's weird.

The main thing is the test paper on the other party's mobile phone that has been changed to a little wrinkled.

"School Committee, ask a question." Yang Xuan's voice is not very soft, it is a bit bright and high-pitched.

Zhou Duan nodded, ignoring Qiao Jing's physics test paper held in the air.

"I used the method taught by the teacher to calculate this question, but I just can't calculate it." Yang Juan turned back to his seat and took the physics book, and pointed to a sample problem on the book with his white fingers.

As he spoke, tears began to flow from his eyes again.

"Don't worry, I'll take a look first." Zhou Duan took the test paper.

As for tears, it's normal to have a temporary disappointment in this kind of high-pressure study, and it's okay to get in the past, so the problem is still on this topic.

In the eyes of the current Zhou Duan, it is a very simple vacuum electromagnetic comprehensive problem.

"There is no gravity in a vacuum," seems to be talking to himself, and finding out the knowledge points obtained by the other party first must be a good way to communicate, and it is also summarized by Zhou Duan before.

"You have this, the internal force is decaying, you use the orthogonal decomposition method, and the force that needs orthogonal decomposition is gravity...... Both. ”

Sure enough, Yang Juan's tears had stopped, and he listened carefully to Zhou Duan's lecture with Qiao Jing.

"Here," Zhou Duan pretended to look at seriously, pointing to a kinetic energy formula, "the equation you wrote is the relationship between the reduced potential energy and the kinetic energy, but there is no gravity in your inference. ”

Don't give the other person time to react at this time.

"It's too careless, this should be the relationship between kinetic energy and total energy loss, the potential energy equation in the book is established on the condition that the device is placed on a flat surface, and the hidden condition of this sentence is the presence of gravity."

In the end, Zhou Duan made a serious summary: "You will do it, remember to review the question carefully next time." ”

Seeing that the "livestock" in his bedroom were gone, Zhou Duan was not in a hurry, took Qiao Jing's test paper, and returned Yang Juan's to her by the way.

"You try it first."

Yang Juan nodded.

"You won't." Zhou Duan looked at Qiao Jing's 73-point test paper, thinking about whether he could go back today before the doorbell was finished.

"Here, the third question of the fill-in-the-blank question, I wrote the unit." Qiao Jing pointed.

Zhou Duan took a look: "emmmm, have you ever thought about it, maybe it's not because of the unit?" ”

Qiao Jing was stunned: "I thought about it, so didn't I come to ask you?" ”

Zhou Duan: What you said makes sense.

Life still has to go on, helping Qiao Jing solve four questions in a row, stuck at the end of the closed door Ling and running to the dormitory building.

…………

The dormitories for the boys of Class 5 are all on the third and fourth floors, and Zhou Duan lives in 404.

As soon as he entered the door, the aura of the big man who had disappeared for a week returned.

"Ha, head of the dormitory, don't blame us, the washing machine is broken." Tong An, who is not tall (160) and has high emotional intelligence.

"The sea poured in today?" Looking at the water level at the door that almost crossed the threshold, Zhou Duan glanced at Zhou Ziheng, who was looking in the mirror.

Zhou Ziheng is known as the first handsome guy in Class 5.

"Brother Heng." Tong An smiled at Zhou Duan and retreated to the edge of Zhou Ziheng's bed, "Don't pretend, something happened to you." ”

Zhou Ziheng got up angrily: "If you don't say it's okay, it's okay." ”

In the eyes of Tong An and several other dormitory members, Zhou Ziheng touched the hairstyle that was frantically tentative on the edge of violating discipline.

"Bedroom chief, if you have something to say, I'll say it first, it's the bedroom next door that splashed me first."

"Who splashed whom?" At this time, a Zhang Jun wearing only underwear walked in.

Zhang Jun looks a little sorry for his name and has a bit of a flamboyant personality, but he is very active in the class.

"Lao Heng said that someone splashed him with water, is that these?"

"He's lying!" Zhang Jun put down the basin and pointed at Zhang Ziheng, "I saw Brother Heng's hand moving first." ”

"Zhang Jun, don't talk nonsense!" Zhang Ziheng came over and grabbed Zhang Jun.

"Look, head of the dormitory, Brother Heng's heart is empty, he wants to kill people and kill his mouth, the head of the dormitory, save me!"

Ignoring Zhang Jun's demon, Zhou Duan just asked casually, and looked at Jiang Cheng, who was lying on the bed, his hair was almost blocking his eyes, and He Runjiang, who was minus his toenails at the head of the bed.

"What about Yan Ziyang?" Zhou Duan looked at the lower bunk that had not been touched.

"He came back before you and is now bathing inside." Zhang Ziheng picked up the mirror again.

Zhou Duan walked to the bathroom with his clothes, and sure enough, he heard the sound of water.

…………

"Dormitory Master!" Zhou Duan's clothed hand was startled by the loud voice.

When I came out, Jiang Cheng was facing Zhou Ziheng and Zhang Jun who were twisting under the window, but his head was noisy in the bathroom.

Yan Ziyang stood on the balcony to blow the wind, the dormitory could not bring a hair dryer, generally everyone took a shower before evening self-study, only Saturday was reluctant to waste time.

"What's wrong?" Put away your clothes and wait for Aunt Xu to arrive.

Looking at the two of them who are not just joking together, Zhou Duan used to have one in one hand.

Jumping over ninety lives is more than just data.

"What's going on?"

Both of them have a bit of a reminiscence, but they are also stubborn.

Finally, Zhou Duan realized that he might have wronged Zhang Ziheng just now, and it was indeed the water that was poured in the bedroom opposite.

Married Zhang Jun, this kid is not a big deal to watch the excitement.

Zhang Ziheng later theorized with Zhang Jun, Zhang Jun's temper was muddy, and the two of them theorized from the reason to the momentum, and then the fist.

"......" Zhou Duan looked at Zhang Jun who was also drunk, and the whole bedroom was unreliable for this kid.

But now the two just can't let go, and between the boys, it's almost the same for one night.

There were still six minutes to go out, and Zhou Duan and Yan Ziyang also blew their hair on the balcony for a while, and then went to bed.

…………

"Didi Woo~~" The elegant ghost screaming tenor blast sound seemed to hit the heart of the person, making Zhou Duan a carp straight.

He Runjiang, who was in the lower bunk, covered his head with a quilt and complained: "I ×××, the school is crazy, can't I change the bell?" ”

Zhou Duan had already folded the quilt: "Change the bell?" Do you think Lao Li's broken horn is low, or is Principal Wen's charging horn too small? ”

He Runjiang, who was in the nest, shivered and didn't speak.

It took five minutes to wash, and the total time to walk out of the dormitory door was controlled within eleven minutes.

I looked at the time: five fifty-one.

At general speed, folding quilts can be faster, and going down stairs can be done in two steps.

In the assembly field in front of the teaching building, the top student with the data memory is already there.

Zhou Duan used the second pillar on the left side of the hall as the standard to find the position of his class's morning running phalanx.

The second person to arrive in Class 5 was a girl named Song Fangfang.

Zhou Duan can safely say that the girls present at this point are all pure makeup.

6:05 is the morning jog, usually the boys arrive at the latest around 59, and the girls get 6:03.

There is no doubt that these times are all data from the teacher's research in a certain limit state.

As for lying in bed, as long as you don't get up...... Zhou Duan looked through the lobby of the teaching building at a huge vine more than ten meters long that resembled a trumpet flower in front of the dormitory building.

Each intersection of the vine has something like a silver bell growing over it.

There is no sound at all on the back of the bell, as for the front......

There has never been a record of a student lying in bed to illustrate whether it is enough?

The morning jog is to run two laps around the school from the assembly field, which is about half an hour.

The calculation of time is about the same as that of the Common Era, except for some cosmic peaks and valleys, most of which refer to artificial stars of uniform specifications.

As time passed, the team began to be complete, and at six o'clock, the familiar figure in Zhou Duan's memory arrived.

Needless to say, Lao Cheng stood on the second floor, earlier than Zhou Duan, but in front of each team were half a meter tall with a pair of glasses at the top...... Compasses.

appeared...... The compass of the experimental class teacher!

Zhou Duan wailed in his heart.

The metal end pierces people, the wooden end heals, and the process is walked down, and there is no bending over in class all day long.

As long as the phalanx is more than the two feet stretched out by the standing compass, you will not be able to avoid this package.

And it's a horizontal row.

What concept, don't be too united.

The potential is forced out, and many students complain to the Education Bureau, and the result is.

Ganges Middle School has borrowed Lizheng Compass, and Guduan Middle School has borrowed a broken sound speaker.

The two bigwigs were completely famous by the former seniors, resulting in many competitions for the students of River Valley Middle School being targeted by other schools.

Do you have to shout slogans for morning runs, don't shout or have a low voice?

Broken Speaker: Come, I'll teach you, open your mouth......

A lot of students are complaining, and then every year more and more transfer students from other planets are coming.

At the end of the morning run, the loudspeaker and the compass stood in the assembly area with the students.

The standing compass in front of each phalanx slowly came together, and then coincided like a phantom.

In the end, there was only one upright compass at the scene, closed the two ends, and the body shrunk to the size of a little thumb and flew into the hands of Wu Zhiming, the head teacher of the experimental class.

As for the broken horn, it put away the blooming bell and turned it smaller, and went into the flower bed on the side.

Leave a neat row of students ready for the day.

…………

On the way back to the classroom, Zhou Duan cast a compassionate look at the six students in Class 6 with everyone.

Yes, those are the six students who have been punished by the standing compass, don't stand too stiffly.

"It's immoral, but I still want to laugh." Pan Yiping was wearing a school uniform jacket, and it was already a little cold this morning.

"Don't be nervous, this Friday is the National Day, the day to celebrate the establishment of the human kingdom and the right to vote in the neutral camp, didn't you find that the teachers are stricter in discipline than before, and there are leaders who came to see our phalanx that day." Tong An on the side is well-informed.
