Chen Fang had just joined Yuya First High School not long ago. She did not recognize many of her students.
“Your name is Gu Nan, right?”
“Yes.”
Gu Nan was popular among the teachers. He was a good student who was reputable in both virtue and art.
Seeing that he was good-looking and good at his study, Chen Fang nodded.
“Yes, I can consider. But Ding Yu is also a suitable candidate. Cheng Ling, what do you think? After all, he is your partner.”
“Well… Teacher, you decide.”
“Then Gu Nan, let’s wait for a while. I’ll inform you when the time comes. Maybe I’ll let you guys read a paragraph each before I decide.”
“Alright, it’s almost time for class. You guys can go back first.”
At this time, Gu Nan remembered the physics question that he hadn’t finished asking. He walked to Sun Qi’s side again, and Cheng Xiao followed suit.
“Teacher, you haven’t finished explaining this question…”
Cheng Ling folded the paper and put it in the pocket of her school uniform. She walked to the office door without looking away.
“Cheng Ling!”
Cheng Ling, who hadn’t reached the office door, was stopped again.
She turned around and saw Sun Qi waving at her.
Gu Nan and Cheng Xiao were standing beside Sun Qi’s desk.
She had no choice but to go back.
“Teacher, what’s the matter?”
“There’s a physics question here. Come and take a look.”
“Me?” Cheng Ling raised her voice.
“Yes, it’s you. Come and see if there are any mistakes.”
Sun Qi handed the physics exercise book to Cheng Ling. Cheng Ling took it and read the question carefully, then calculated the result in her mind.
“You can only use this formula in a vacuum. You had forgotten that the conditions changed in the second half of the experiment.”
“So if you only use this formula, it’s certainly not right. You should solve this question in two steps. First, calculate the conditions before the air enters, then the conditions after the air enters. Then, deduce another formula.”
Cheng Ling said while pointing at some specific conditions on the question with the tip of her right index finger.
Gu Nan listened very carefully and soon realized the problem.
“Oh, so that’s how it is.”
Cheng Xiao, who was standing at the side, was standing behind Gu Nan at this time. Her eyes were full of resentment toward Cheng Ling. She didn’t listen at all. She was only thinking in her heart that why Cheng Ling was always the one doing all the good things now?
Could she understand physics?
After listening to Cheng Ling’s explanation, Sun Qi nodded.
“That’s right. When you do the questions, don’t just apply the formulas. You have to think carefully about the circumstances when you can use these formulas. Many of the questions in the physics competition cannot be solved by applying formulas directly. Instead, you have to use these formulas flexibly.”
Cheng Xiao retracted her gaze, then pretended to be surprised.
“Sister, when did you become so good at physics? As your sister, I don’t even know.”
Gu Nan also looked at Cheng Ling, waiting for her answer. He didn’t expect Cheng Ling to be so good not only in English but also in physics!
But why had she been in the last place for the past two years?
Cheng Ling put the exercise book back on the table and looked at Cheng Xiao, not avoiding her eyes.
“You’re overthinking it. The teacher just happened to teach this question in our class.”
Cheng Xiao smiled. She didn’t know whether to believe it or not.
Anyway, Cheng Ling didn’t care about the attitude of others.
She nodded to Sun Qi and then went back to class.
Gu Nan and Cheng Xiao understood the physics problem now and left the office one after another.
Sun Qi was tidying up the desk in the office. He knew that what Cheng Ling said just now was not the truth.
This kind of question had reached the standard of the competition questions. Why would the physics teacher of class 10 teach this kind of thing in physics class?
He shook his head in disappointment.
Judging from Cheng Ling’s attitude just now, it seemed that she did not plan to participate in the selection.
Before Cheng Ling returned to class, the bell had already rung. She could only enter through the front door.
She knocked on the door and greeted the teacher.
The one who was currently in class was the language teacher. This teacher had always been biased against Cheng Ling. He felt that Cheng Ling always did not listen to the class and did not complete her homework properly.
Seeing that Cheng Ling was late today, she took the opportunity to give Cheng Ling a good scolding.
“What’s going on? It’s only the first few classes and you’re already late?”
“The third year of high school is the most important time. Cheng Ling, you have to change your lazy and irresponsible attitude towards learning. Otherwise, what will you do in the future?”
Cheng Ling stood at the door of the classroom. The sunlight shone in from behind her. Her face could not be seen clearly, but it blurred her outline.
