Probably because of the exam, the two self-study classes passed quickly, and the physics teacher announced the end of class after collecting the test papers, and Gu Yuan stretched lazily in his seat.

"Brother Yuan, have you written the last question?" Li Haotian leaned in and asked, "Forget it, you must write it," without waiting for Gu Yuan to answer, Li Haotian continued, and Gu Yuan had no choice but to smile politely.

"Brother Yuan, I need you to preach and solve my doubts now, and tell me the solution to the last question! If I don't understand this question, I won't be able to sleep well tonight," Li Haotian looked at Gu Yuan with a look of anticipation.

Hearing that Li Haotian was discussing the last question of physics with Gu Yuan, Su Xiaoqing and Chi Yu also turned around and looked at Gu Yuan together.

Seeing that the three of them were looking at him, Gu Yuan smiled and said: "This question is actually not very complicated, the essence is to test our mastery of force analysis, as long as we can draw the force analysis diagram correctly, this question is very simple......"

"Okay, Brother Yuan, let's get straight to the point!" Li Haotian muttered in a low voice, Gu Yuan ignored Li Haotian and continued to talk about the topic step by step according to his own ideas, analyzing the force on the paper as he spoke.

As he spoke, there were more and more classmates around Gu Yuan, and Gu Yuan was completely surrounded, and everyone was listening carefully to Gu Yuan's ideas for solving problems, and they didn't even hear the bell ringing in class.

When the head teacher Ye Wenjun walked into the classroom, after seeing this scene, he smiled and did not speak, and silently withdrew from the class, until Gu Yuan finished talking about this question, and the students returned to their seats with the harvest, Ye Wenjun returned to the classroom belatedly.

"Brother Yuan, your solution idea is fantastic, now I know what I did wrong, I can sleep well," Li Haotian said in a low voice, "It's not good, I'm using my brain a little too much, I need to take a break." ”

As he spoke, Li Haotian took out a copy of "Story Club" from the drawer and read it with relish, Gu Yuan was helpless about it, he shook his head with a smile, Ye Wenjun sat on the podium, and the students below were quietly studying, except for Li Haotian who was reading "idle books".

Gu Yuan looked at the scratch paper that he had written full of ideas for solving the problem, took out a clean piece of paper, and continued to study the question he just talked about, although he had already explained it very thoroughly, but Gu Yuan still did not give up, and wanted to see if there was a more understandable method.

The last self-study class passed like this, and when the school bell rang, Gu Yuan also put down the pen in his hand, exhaled lightly, looked at another piece of scratch paper full of solution ideas, and smiled with satisfaction.

"Brother Yuan, haven't you already talked about this question once? Why did you write the problem-solving process again? Li Haotian also saw the manuscript paper full of ideas for solving the problem in Gu Yuan's hand, and asked puzzledly.

"Deepen your impression," Gu Yuan said with a smile, and carefully sorted out the piece of paper, "Why aren't you ready to go back?" I usually see you running fast after school, huh? Seeing that Li Haotian was indifferent to school, Gu Yuan asked more.

"Wait a while, I'll talk about it after I've finished reading this story," while speaking, Li Haotian glanced at the door of the classroom from time to time, Gu Yuan was not surprised by this, and packed up his things.

After a while, seeing Su Xiaoqing getting up and preparing to leave, Li Haotian immediately glanced at the door of the classroom, and sure enough, he saw the familiar person, and then immediately packed up his things and got up to leave.

"Brother Yuan, you haven't packed your things yet? I see you've been tidying up for a long time, let's go! Let's go! Before leaving, Li Haotian invited Gu Yuan to go with him.

"You go first! I still have some things that haven't been packed up," Gu Yuan replied as he sorted out the test papers and books on his desk, in fact, his seat was tidy enough.

"Can't you clean it up tomorrow? I'm really convinced of you, then I won't wait for you to come and leave first," Li Haotian walked out of the classroom quickly after speaking, catching up with the two people in front of him.

Because the time of the last train in summer was slightly extended, Chi Yu still sat quietly in her seat, digesting the physics question that Gu Yuan talked about just now, although Gu Yuan had already explained it in great detail, but she still didn't understand some things, after all, physics was too bad.

After nearly ten minutes, there was basically no one in the classroom, Chi Yu slowly got up to pack up her things and prepare to leave, when she turned around, she found that Gu Yuan was still fiddling in her seat, and couldn't help laughing: "You haven't cleaned up for such a long time?" I thought you were gone! ”

"I cleaned it up right away, the seats were too messy, and I didn't usually clean up much, so this time I was in place at one time and cleaned up thoroughly," Gu Yuan scratched his head and said with a smile, in fact, he cleaned up his seat after Li Haotian left, and even Li Haotian's seat was simply cleaned up.

Chi Yu waited for Gu Yuan for a while, and then the two walked out of the campus side by side.

As soon as I arrived at the bus stop, a car came, and the two got on the bus one after the other, Chi Yu was in front and Gu Yuan was behind, and after sitting on the seat, Chi Yu took the lead and said:

"I haven't drunk the milk you bought today! But the taste is pretty good. ”

"Really? Then I have to taste it next time," Gu Yuan said with a smile, reached into his pocket with his right hand, took out a piece of paper full of writing, and handed it to Chi Yu.

Chi Yu took it with a puzzled look on his face, and looked at it fixedly, isn't this the process of solving the physics problem? And it was different from the method that Gu Yuan had explained in the classroom before.

"It's okay to be idle, I thought of a simpler idea in the last class, so I wanted to give you a reference," Gu Yuan said with a smile.

Hearing this, Chi Yu immediately looked at it seriously, indeed, it was better to understand than the method that Gu Yuan talked about before, Chi Yu smiled and said thank you and continued to read it, and if there were some things he didn't understand, he asked generously, and Gu Yuan told her very patiently.

The bus arrived at Gu Yuan's community, Gu Yuan reluctantly got off, the car restarted, Chi Yu looked at Gu Yuan's figure outside the car, and looked down at the paper in his hand, a smile unconsciously appeared on his face, with Gu Yuan's help, she had completely mastered this type of question.

After returning home, Chi Yu still took out a notebook as always, wrote today's date, and then began to record, when he stopped writing and stopped writing, he carefully sandwiched the paper that Gu Yuan wrote full of the problem-solving process in the notebook, and then washed and went to sleep with a smile.

The next day, the atmosphere on campus was obviously different, the whole campus was quiet, and the leaders of the first and second years of high school patrolled the campus to avoid the first and second year students from making big noises.

Because there is still a week to go before the college entrance examination, in order to ensure the quality of the rest of the third year of high school, the school has canceled the morning exercise and early reading, this week the students of the third year of high school do not have to get up early, just go to class at 8 o'clock in the morning and read early.

At about half past six in the morning, the classroom of the eighth class of high school was already full, and since there was no longer morning reading, all the students were quietly studying on their seats, but there were also some students discussing the problem in a whisper, Ye Wenjun just came to see it and left.

"Hey, Brother Yuan, don't you say that the treatment of the third year of high school these days is quite good," Li Haotian said in a very small voice.

"What? Are you envious? Gu Yuan asked with a smile.

"I can't say envy, I just have some expectations, I hope that time will pass faster," Li Haotian looked at the empty senior high school teaching building, his face full of yearning.

"Otherwise, if you apply for skipping a grade, you will be able to take the college entrance examination in a week," Gu Yuan joked.

"Brother Yuan, you think too highly of me! Isn't it in vain that I'm going to take the college entrance examination? Li Haotian said with a smile.

At this time, Su Xiaoqing suddenly turned around, startling Li Haotian, thinking that her voice had disturbed her, so she hurriedly shut up and pretended to study seriously.

"Gu Yuan, you can help me take a look at this question," as he spoke, Su Xiaoqing handed the math problem in his hand to Gu Yuan, Gu Yuan took it and looked at it seriously, seeing that Su Xiaoqing was not here to blame, Li Haotian exhaled with relief.

Then, Chi Yu also turned his head, glanced at Gu Yuan, who was giving Su Xiaoqing a lecture, and then looked at Li Haotian.

"What? Did what I said just now also affect you, if so, I would like to sincerely apologize to you here," Seeing that Chi Yu was also looking at himself, Li Haotian said embarrassedly.

"No, I just want to ask you for a favor, you can help me look at this physics problem," Chi Yu said with a smile.

"Oh, that's right! No problem, of course no problem, if you ask me, you are asking the right person, not me speaking wildly! Although I don't have the strength of Brother Yuan'er's 'pervert', I still have the strength to lose it," Li Haotian took the exercise in Chi Yu's hand with a smile, and after thinking for a while, he talked to Chi Yu.

With the broadcast of the radio in the classroom, it was time for breakfast, and the first-year high school students all walked towards the canteen softly, not daring to make too much noise, Gu Yuan and Li Haotian met Zhang Wu on the way to eat, and the three of them chatted quietly while walking towards the canteen.

When the three of them had breakfast, the senior high school students also walked into the classroom one after another, and after returning to the class, Gu Yuan was surprised to find that there was an extra bottle of milk on his seat at some point, Gu Yuan picked up the milk and smiled, and immediately guessed who sent it.

At this time, Chi Yu also walked into the classroom with a bottle of milk exactly the same as the one on Gu Yuan's desk, Gu Yuan said with a smile:

"Thank you for the milk, I said you don't have to pay me back so soon!"

"Huh?" Chi Yu was stunned for a moment, and continued to speak: "You may have misunderstood, this is the milk I am going to return to you," as he spoke, Chi Yu raised the milk in his hand.

"Huh? Didn't you send it? So who else? Could it be Li Haotian? That's not right! I'm back with him! Now it was Gu Yuan's turn to have questions on his face.

"Gu Yuan, I know who it is," a boy sitting behind Gu Yuan said with a smile.

"Who?" Gu Yuan looked at the boy and asked impatiently, but the boy just gestured to Su Xiaoqing's seat with his eyes.

"You mean......" Gu Yuan also looked at Su Xiaoqing's empty seat, and the boy nodded again.

Chi Yu also smiled and handed the milk in his hand to Gu Yuan, and returned to his seat and sat down.
