<h4>Chapter 108: Competition Questions</h4>


    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 popr 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 timees. Maybe I’ll let you guys read a paragraph each before I decide.”


    “Alright, it’s almost time for ss. 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 exining 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 calcted the result in her mind.


    “You can only use this form in a vacuum. You had forgotten that the conditions changed in the second half of the experiment.”


    “So if you only use this form, it’s certainly not right. You should solve this question in two steps. First, calcte the conditions before the air enters, then the conditions after the air enters. Then, deduce another form.”


    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 exnation, Sun Qi nodded.


    “That’s right. When you do the questions, don’t just apply the forms. You have to think carefully about the circumstances when you can use these forms. Many of the questions in the physicspetition cannot be solved by applying forms directly. Instead, you have to use these forms flexibly.”


    Cheng Xiao retracted her gaze, then pretended to be surprised.


    “Sister, when did you be 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 thest ce 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 ss.”


    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 ss.


    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 thepetition questions. Why would the physics teacher of ss 10 teach this kind of thing in physics ss?


    He shook his head in disappointment.


    Judging from Cheng Ling’s attitude just now, it seemed that she did not n to participate in the selection.


    Before Cheng Ling returned to ss, 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 ss was thenguage teacher. This teacher had always been biased against Cheng Ling. He felt that Cheng Ling always did not listen to the ss and did notplete her homework properly.


    Seeing that Cheng Ling waste today, she took the opportunity to give Cheng Ling a good scolding.


    “What’s going on? It’s only the first few sses and you’re alreadyte?”


    “The third year of high school is the most important time. Cheng Ling, you have to change yourzy and irresponsible attitude towards learning. Otherwise, what will you do in the future?”


    Cheng Ling stood at the door of the ssroom. The sunlight shone in from behind her. Her face could not be seen clearly, but it blurred her outline.
