Three generations of love in Lanxi Town

Chapter 124 112: "Teacher, I think Ouyang Jun did nothing wrong."

The first class in the morning started.

The science teacher's surname is Lu, he is straight and fat, so he is nicknamed "Fat Old Lu".At this moment, he walked in swaggeringly, his plump body almost hanging on the door frame.

Lao Lu wrote down yesterday's homework questions on the podium, and his voice was like a bell: "Everyone has done their homework, who is going to rush to answer this question?"

Ouyang Jun couldn't wait to raise his hand.

"Teacher, the answer is a=2m/s2"

"Write down the process on the blackboard." Lao Lu handed over a piece of chalk.

Ouyang Jun took the chalk from the teacher and began to write step by step.The handwriting on the blackboard was very neat, but when the chalk was returned to Lao Lu, Ouyang Jun saw the regret in his eyes.

"Teacher, I..."

"It's okay, please go back. Does anyone see what he did wrong?" This last sentence is naturally asked to the whole class.

A short classmate wearing glasses stood up, "Ms. Lu, I know."

"Then tell me."

"Student Ouyang didn't add the words 'according to Newton's second law' before F=umg, so the calculation was wrong."

Lao Lu nodded in satisfaction, "That's right, student Ouyang must not be sloppy."

"Teacher, I don't think Ouyang Jun did anything wrong." Li Qingning retorted suddenly.

Lao Lu frowned, "When circular motion in a vertical plane uses Newton's second law, it must be marked. If it is not marked, it is wrong. Listen carefully."

Since it is impolite to sit and talk to the teacher, Li Qingning stood up, "Teacher, have you not considered that he may not be using Newton's second law?"

Lao Lu became a little curious now, and said: "If you can tell why Ouyang Jun's answer is right, I can choose you to be another class representative, and there happens to be one missing!"

Ouyang Jun looked at Li Qingning suspiciously, even he didn't understand why she was so serious about a wrong question.

Sensing Ouyang Jun's gaze, Li Qingning winked at him quietly: Trust me.

Then, she looked directly at the teacher and said loudly: "The ambiguity lies in the "F" in the process - if "F" means friction, then Ouyang Jun's answer is undoubtedly wrong; but in his answer "F" "It means gravity, and the process actually uses the kinetic energy theorem and the law of conservation of mechanical energy, so it doesn't have to be marked. Therefore, I think his answer can't be faulted."

Lao Lu looked at the blackboard, pondered for more than half a minute, finally showed a smile on his face, and praised: "Yes, we can do this. I will do what I say. Would you like to be a class representative?"

"Thank you teacher." Li Qingning nodded and sat back in her seat.

"Wow! Sister Qingning, you are amazing! You even refuted the teacher!" When eating at noon, Ouyang Jun couldn't restrain the admiration in his heart. "

"No, this question is just a coincidence." Li Qingning stuck out her tongue and asked.

"That's amazing!" Ouyang Jun was full of praise.

"Amazing?" Li Qingning smiled, "Then I am also the representative of the science class now, and you will listen to me about the science class in the future. I will tell you to go east and you can't go west."

"Why?" Ouyang Jun protested.

"Hmm... You said you would marry me in the morning during self-study! You want to be my future husband, why don't you treat me better now?" Li Qingning teased.

As soon as these words came out, Li Qingning blushed—it was broken, Tu Qiong realized that this was purely true!
Ouyang Jun was stunned for a moment, "Forget it, if you marry me in the future, I'll take care of the class representative."

"What the hell." Li Qingning prevaricated.

In the afternoon, Chen Zhenhua probably finally remembered that he was the head teacher of Class [-], so he walked into the classroom and taught two math lessons.

I don't know why, but I obviously didn't feel how serious Chen Zhenhua's lecture was, but everyone listened with great interest and benefited a lot.

The two classes passed quickly, and the assigned homework was just finished in the self-study period. Before the students recovered, the school bell rang.

In two days, most of the students got to know each other well, and Ouyang Jun also made two friends.But for some reason, Ouyang Jun always felt that there was something missing when playing with them, and it was more interesting to play with Li Qingning.

Outside the window, rows of fiery red maple trees dance with the autumn wind, and the swaying leaves make a "rustling" sound.Ticadas hide among the leaves, seizing their last moments to play a natural movement for the blue sky above their heads.

"It's so beautiful, but it's a pity I wasn't born in autumn." Li Qingning was deeply attracted by Qiu Jing, and she sighed unconsciously.

"The leaves are falling, the vegetation is dilapidated, what's there to see in autumn?" Ouyang Jun didn't understand.

"Then which season do you like?" Li Qingning looked away from the window and looked at Ouyang Jun.

"Of course it's spring. When spring returns to the earth, everything is revived, and everything is full of vigor and vitality!" Ouyang Jun carried her schoolbag and signaled that she could go by herself.

Li Qingning smiled, "That's the season I was born in."
