What is potential energy, what is kinetic energy, and how is potential energy converted into kinetic energy?

She understands all these words individually, but how can they be so complicated together?

Shi Jing only felt that these things were more difficult than the obscure rules she had memorized, and after listening to a class, she didn't understand anything.

Shen Silent has been holding his head in a daze in this class, and he has nothing to do, he observes the small table next to him, and his face has been full of entanglements since the beginning of class, doubting life, etc., these vivid little expressions he can see clearly, and he can't help but smile in his heart.

"What, I don't understand the lesson?" Shen Silent turned the pen lazily, and his slender fingers turned quickly, bringing out afterimages.

Shi Jing looked at the time, there were still five minutes to go to class, she said with a bitter face, "I can understand what the teacher says, but I don't know what it means when it is connected, I haven't learned anything after one class." ”

"Stupid." Shen Silent pursed his lips and said casually, "The old man in physics is too complicated, I'll tell you when the class is over, this kind of simple knowledge is actually not difficult at all." ”

"Okay, then I'll copy the notes first, and you can tell me after class." Shi Jing smiled shallowly, and the unhappiness on his face disappeared instantly.

The five minutes passed quickly, and the physics teacher coughed twice and took out a large stack of test papers, "The class representative will send these test papers, three for each person, and hand them in to me tomorrow morning before the self-study class." ”

Shi Jing was stunned when she got the test papers in her hand, she was dizzy with the dense test questions, she lay on the table with a sad face, and three test papers were assigned in the second class in the afternoon, and when she got home in the evening, she didn't dare to imagine how much homework would accumulate.

As far as she knows, the sophomore students are not the hardest, and when they reach the third year of high school, they will know what hell on earth is.

Senior high school students have to start studying non-stop every day as soon as they wake up, from early morning to late at night, they can't sleep enough every day, and they can't finish their homework.

Even so, they have to make time for cram school, and if they are not careful, they will be overtaken by other hard-working classmates, and everyone is eager to break the time into three parts.

The sea of books is endless, and the current hard work and efforts are exchanged for a better future, and they are willing to eat.

As soon as she got out of class, she obediently took the textbook and asked Shen Silent for advice, and she marked out a large number of knowledge points, "This, and this, I don't understand it very well." ”

The corners of his mouth twitched speechlessly, a class lasted forty-five minutes, and his little table mate seemed to be trying to listen to the lecture, but in fact, he didn't learn anything, everything had to be re-taught.

Shen Silence's voice is particularly good, with the unique clarity of his youth, he writes and draws in books, and the steps explained are extremely detailed, and the original complex principles have become particularly simple and easy to understand in him, Shi Jing suddenly realized, "Wow, I understand, is this the case." ”

Shen Silent paused, he had never lectured to others, this was the first time he tutored others, he didn't have a score in his heart about whether he was good or bad, seeing Shi Jing's clear look, his eyebrows were dyed with a smile, "Are you sure you will?" Come and do these questions, and I'll check for you later. ”

Shi Jing calculated those formulas, and quickly answered one question after another.

Shen Silent watched from the side, occasionally pointing out a few words, he found that this rumored first to last in the grade was actually very smart, and she could draw inferences from each other with a few words, and if she studied hard, her grades would definitely not be bad.

The classmates in the class couldn't control their eyes and looked here, "Shen Silence, he actually took the initiative to teach people to learn, is it that I opened it in the wrong way today, otherwise how could I hallucinate." ”

"You read that right, the big guy is just making up for Liang Xia, don't say it, these two look very eye-catching, just be together."

Yu Xiaoyun said softly, with a shy smile on her face, "You talk quietly, don't disturb Liang Xia's study." ”

A mischievous boy sneered, "Okay, since it's the little cutie Xiaoyun who speaks, then we won't speak." ”

Yu Xiaoyun blushed shyly, "You guys, don't joke around, I'm not a cutie." ”

Over there, Shi Jing's writing speed slowed down significantly, and it took several minutes to write one.

Shen Silent knocked on the table, "What do you think, so obsessed?" ”

Shi Jing blinked, "I'm wondering why you don't understand so much if you don't listen to the lecture?" ”

"Do you believe me when I say I sleep and listen to lectures?"

Shi Jing shook his head, "I don't believe it, you must have gone home and secretly made up for the class." ”

"Cut, just this kind of pediatric course, you can use your brain, and I still need to make up for it?" Shen Silent snorted softly, and he was extremely conceited when he said this.

Shi Jing had to take it, Shen Jing was very smart, and he didn't have a hard time learning anything, if he studied dim sum, the first place would be his, and then the pressure on his classmates would be even greater.

Shi Jing dropped the last stroke, she checked it first, and after confirming that there was no problem, she handed the paper to Shen Si, "I'm done, you can help me read it." ”

Shen Shi only glanced at it, and then gave an affirmative answer, "Yes, all right." ”

Shi Jing's expression was very excited, as if she had received some great compliment, her smile was very bright, "You taught me well, thank you, my little tablemate." ”

Shen Silence's heart throbbed, the girl in front of him smiled like a flower, and her delicate face seemed to coincide with another beautiful face, which was obviously a completely different appearance, but he felt a long-lost sense of familiarity from it, which made him very nostalgic.

Soon it was time to get out of school in the afternoon, the school provided a dormitory, and students who were far away from home could choose to live in the school, and the original owner had a single apartment nearby, which was particularly beautifully decorated, and he had been living there.

Shi Jing harvested twelve test papers on the first day of school, all of which were homework tonight, and she also had to recite two texts and copy ten ancient poems, she now wanted to cry without tears, she was a thousand-year-old person, but she didn't expect to be stumped by a small school.

Shi Jing swore that she had never thought that being a student would be so difficult, and it would be more difficult than any other world she had ever had.

She sat in her seat for a long time without moving a step, her heart turning a thousand times, thinking about how to create an opportunity to be alone with Shen Lone.

Before she could come up with a solution, Shen Silent took the lead in speaking, "Where do you live and how do you plan to go back?" ”

Shi Jing's eyes lit up, she reported an address, and said in a soft voice, "Dijing Villa, it's far away from here, can you send me?" ”

Shen Silent once again moved one step ahead of his brain, he picked up Shi Jing's schoolbag and strode out, "Let's go, just drop by." ”

Shi Jing's fart kept up, and he didn't forget to take the bottle of orange soda, and drank a sip of the fragrance of oranges in his mouth, which was cool and thirst-quenching.

Qiao Yushu sat lazily in place, not dissatisfied with what he had been left behind.
