"Smart, I have pen and paper here, you can do the calculations yourself first!" Teacher Song opened the bag, took out the pen and paper and put them on the table.

Chen Yu started to make pretentious calculations, scratching his head and head from time to time, as if he had a new problem.

Teacher Song was not in a hurry, drinking lemon tea while watching.

After a few minutes, Chen Yu smiled, returned the pen and paper to Teacher Song, and stared at her, his eyes full of curiosity.

The handwriting on the paper is very beautiful, just like the printed regular script, which is pleasing to the eye.

"The coefficient of friction is correct."

"Then how to tell whether it has wheels?"

Teacher Song said with a smile: "This involves not only basic knowledge, but also understanding and analytical skills. As a language, we all know that Chinese, English, and physics are not rigorous. This characteristic is also caused by our tendency to argue...

..."

The explanation was very detailed and in place. Chen Yu was watching and listening, mainly to prevent the other party from asking sudden questions.

"The friction coefficient of 0.05 is relatively small, compared with the data in the reference materials, so there should be wheels, which is rolling friction."

"Teacher, I understand, you are so awesome!"

"Then tell me, other than this, why do you believe it is a wheel?" Teacher Song has the mentality of taking a test.

Chen Yu can no longer hide his clumsiness, because teachers like smart students.

"The horizontal speed of the object when it leaves the table is greater than 0, which means that the friction force experienced by the object is smaller before, so the friction coefficient is further less than 0.05, which confirms that it has wheels."

"That's it!" Teacher Song showed a happy smile, spending so long time talking was not in vain.

"I finally know why Qiao Yingzi is a top student. At least half of your credit is in it."

There is nothing wrong with what Chen Yu said. Whether she is coaching her daughter to study or forcing her daughter to study, her grades will always be improved. Whether it will affect her mental health is another matter.

"You kid has learned how to flatter me!" Teacher Song's tone was a bit reproachful, but her eyes turned into crescents when she smiled, much like Qiao Yingzi.

No matter what age women are, they like to be duplicitous. It is important to be able to distinguish correctly, otherwise they will be a straight man.

"It's unfair. I'm telling the truth. Qiao Yingzi ranks first in the grade every time she takes exams, and Huang Zhitao ranks second every time. Why do you think that is?"

"Why?" Teacher Song's smile continues.

"Their grades are almost the same. Huang Zhitao's parents can't provide guidance, but Qiao Yingzi can suppress her every time. Who dares to say that it's not due to you?"

"Keke, you make it sound as if Yingzi and I are bullying Huang Zhitao!"

"That's not what I meant. The school requires parents to help us study. It's just that you try harder than other parents, which makes me a little jealous."

"Hahaha, the word envy, jealousy and hate is so funny when you say it like that!"

"Haha!" Chen Yu smiled shyly and wanted to say in his heart, Yingzi, hold on.

No wonder the girl is so flat. The main reason is that she is under too much pressure to study. Then again, a flat girl can better bear the effects of force. If she is not in good shape, she cannot blame Qiao Yingzi, but Teacher Song.

"Classmate Ji Yangyang, eat slowly, I have to go back!"

"Teacher, won't you sit down for a while?"

"It's time to go back and cook!" Teacher Song stood up with her bag in hand, moving very neatly.

Chen Yu quickly stood up and said, "Goodbye, teacher!"

Qiao Yingzi, who was watching on the sidelines, quickly ran out of the shopping mall, met her mother at the entrance of the shopping mall, and then stopped a taxi while chatting and laughing.

"Taozi, come in quickly!"

Chen Yu's loud voice attracted the attention of people around him, and Huang Zhitao walked into the restaurant bravely.

"Sit down quickly, I'll help you order whatever you want to eat!"

"No, I'm not hungry."

Chen Yu shouted again: "I want blueberry-flavored pop-pop, cheese tart, spicy French fries, and macaroni."

Huang Zhitao wished she could get under the table because her classmate's behavior seriously affected other guests.

The staff in the store quickly ran over and said: "To order food in our store, you need to go to the ordering counter yourself."

"I just didn't want to go, so I called you!"

"Sorry, we don't provide this service."

"Then I'll keep shouting, please do as you please!"

If you are not frivolous when you are young, then you are still a young person. You will have to wait until you enter the society to talk about the rules, and then set them up for the employees.

"Ji Yangyang, I'll order it myself."

"No!" Chen Yu grabbed Huang Zhitao and his tone was non-negotiable.

These shabby restaurants want to make money but don’t want to hire waiters. If it hadn’t been for Teacher Song’s idea, I wouldn’t have come in.

"You are making trouble unreasonably!"

"Hey, I need to argue with you about this. Why is it so unreasonable to come here to dine and ask you to provide services?" Chen Yu's voice was as loud as ever.

"I already told you, the store does not provide this service!"

Huang Zhitao looked worried. Classmate Ji Yangyang was so domineering and unreasonable.

"Xiao Li, you go and do your work first!" A woman walked over quickly, "Handsome guy, if you have any questions, tell me, I am the store manager here."

A casual white shirt and drapey wide-leg pants show off your figure. Curly hair and light makeup add to your appearance. The store manager is pretty.

"Sit down and talk!" Chen Yu sat down first, holding Huang Zhitao's little hand and refusing to let go. This was to give her courage, a very warm-hearted behavior.

The school belle’s face was red, her little head buried in her arms, and she didn’t dare to look at anyone.

"Thank you!" The female store manager sat next to Huang Zhitao.

"I just want you to order a meal. Why am I being unreasonable? Please give me an explanation!"

Solving problems is naturally done face to face, looking at each other to show respect, which is also the most basic courtesy.

"You have already ordered food, so you should know our rules."

"My parents ordered this. I didn't know it when I came in. There was no sign at the door telling customers that ordering service was not provided!"
