Recently, at home, my family has been in a lot of trouble; At school, my personal relationship problems were not going well. These things made me feel very depressed.

When I'm upset, I want to listen to music. But the school didn't allow us to bring our phones to school. So I bought an mp3 specifically for listening to songs. At first, I just listened to it while walking around campus, but then I gradually became addicted to listening to it and started listening to music with headphones on my bike.

When my mother found out about this, she repeatedly advised me not to listen to songs while riding a bicycle, and I knew that it was not safe to do so, but there was nowhere to complain and it was difficult to transfer the anguish in my heart, so I had to use this method to vent. So no matter what she says, I'm always in disobedience.

At school, the life of the three people together every day continues.

The academic proficiency test is coming soon, and this semester, everyone in our grade will have to take the six subjects of politics, history, geography, physics, chemistry and biology. So, starting this semester, our science students will also take liberal arts classes, and their liberal arts students will also take our science classes.

In fact, the academic proficiency test is very simple compared to our usual monthly exams and mid-term final exams. Our academic proficiency test results are not expressed by scores, but by grades. A, B, C, D, four grades, as long as there is no subject with D, we will be able to graduate smoothly by then, otherwise, we will have to retake the exam.

For our Class A students, the key is whether we can get an A in the academic proficiency test. In the future, when applying for universities, some schools may also require students to score in academic proficiency tests, some good schools may require students to get fewer than a few B's, and some universities will even require students to get A's in all subjects.

Therefore, our three Class A students are very eager to get a good score in the academic proficiency test.

For science (arts) students, the science (arts) exam is naturally not a problem, the key is whether the arts (science) exam can get A, so recently, many science (arts) students are holding the arts (science) materials every day.

I'm not nervous. Liberal arts have been my forte since junior high school. Although I didn't study liberal arts after I was divided into liberal arts and sciences in the first semester of high school, everyone said that the difficulty of this academic proficiency test was small, and now I just want to learn some liberal arts concepts roughly, isn't it very simple for me? Besides, I won't be able to go to any top universities in the future, and even if I get a B in one or two subjects, it's not a big deal. As for C, this is not considered, I believe that with my strength, I will not only take C.

So, I still do what I should do, except for the time in the liberal arts class and the evening reading the liberal arts, I still spend the rest of the time on the science, and I don't squeeze out a lot of time every day to memorize the concepts of the liberal arts and read the topics of the liberal arts, like some students.

I'm pretty relaxed, but the president is different. Ever since our entire grade had been in a state of "preparation for the Scholastic Proficiency Exam", he would come to us almost every day with a science question -

"Lin Haiyuan, when an object is moving in a curve, how do you look at the direction of its velocity at a certain point?"

Lin Haiyuan looked at it, a very basic question. He lost interest in an instant.

"Such a simple question, don't look for me, I don't have time to answer it for you." He said.

So the president had to come to me-

"Yi Yin Fei, you can teach me."

I can't bear to say no to other people's requests, and I usually say yes to what I can help. Besides, I think my relationship with the president is even better than my relationship with Lin Haiyuan, and my good friend needs my help, how can I refuse? In the past, I was always unable to occupy a place in the discussion between the president and Haewon Lin about studying, but now that I can finally help a university bully like the president in my studies, I am naturally happy to feel my own value.

As a result, answering science questions for the president every day has become my repertoire.

The president worked very hard to study science. He didn't just come to me after school to ask questions, even in gym class.

There was a physical education class, and I had nothing to do and went to the meeting point of class 6 to find the president. When I got there, I saw it, hey, the students of Class 6 were rehearsing the recitation program, they should be preparing for the New Year's Day art show. I looked into the line, but I didn't see the president. Then a voice came from behind me—

"Yi Yin Fei."

"President, you're here." The president was behind me, leaning against a tree.

"President, don't you have to rehearse?" I asked him.

"I didn't attend." He replied. I don't think he's a keen group person, so I guess it's a waste of time to participate in this kind of activity.

"Yi Yin Fei, I have a few chemistry questions for you." He said.

"You have to study all of this in gym class? You ask. ”

"What is the nature of redox reactions? Is it the rise and fall of valence? ”

"No, the essence of redox reaction is the transfer of electrons, and the characteristic of redox reaction is the rise and fall of valence."

"What are the common oxidizing agents?"

"Oxygen, this is the most classic thing you can't forget. Others such as chlorine, concentrated sulfuric acid, potassium permanganate, and nitric acid are all common oxidants. ”

"What about common reducing agents?"

"Metals like iron, aluminum, zinc, but also carbon and hydrogen."

"Is sulphur dioxide an acidic oxide?"

"yes."

"What about carbon dioxide?"

"Yes."

“......”

"Huh? President, this seems to be what we learned in the first semester of high school, right? Didn't you have a liberal arts and sciences at that time? Why don't you know all this? ”

"I'm not good at science, and for me, these things are hard to die for."

"I see." It's no wonder that I haven't heard the president's name before the division of arts and sciences, so it turns out that I was held back by science.

One day at noon, when Lin Haiyuan and the president and I walked out of the seventh class classroom, the president suddenly said that there was a chemistry problem and he wanted me to go to the sixth class to answer it for him. I agreed, so the president asked Lin Haiyuan to go with him-

"Lin Haiyuan, I'm going back to Class 6 and let Yi Yinfei teach me chemistry, you can go with me too."

"No, go by yourselves." Lin Haiyuan disagreed.

"Let's go! Come with me! ”

"Don't go! I'm going to eat. With that, Lin Haiyuan walked downstairs by himself.

"Just come with me!" The president stood at the turn of the stairs and begged Lin Haiyuan to go back to Class 6 with him, but Lin Haiyuan turned a deaf ear and left without looking back.

The poor president stood at the turn of the stairs, looking at the sixth class at the end of the corridor on the second floor, and at the figure of Lin Haiyuan leaving, looking like he couldn't make a choice.

Is it so hard to choose? It can be seen that his heart is very entangled at the moment. Is it a question of choosing chemistry, or choosing to go with Lin Haiyuan?

I stood silent, looking at him with a smile on my aunt's face, waiting for him to make this difficult choice.

Eventually, he made his choice. He turned around, walked to Class Six, and said to me, "Let's go." ”

"Hmm." I followed. I was amazed.

is so reluctant to Lin Haiyuan, even if he doesn't want to be separated from him for a day, it can be seen how much he loves Lin Haiyuan in his heart; In order to ask chemistry questions, he did not hesitate to give up the opportunity to walk with Lin Haiyuan, which can also be seen that he attaches great importance to the academic level test. Poor president, how entangled he was just now!

After answering his questions, we walked out of the school building side by side. The president chatted with me all kinds of gossip along the way, which made me feel very interesting to be with him. If he was alone with Lin Haiyuan, it would be much more embarrassing than this. It's always me working hard to find a topic, otherwise Lin Haiyuan would be silent.

I secretly felt that it would be more enjoyable to be with the president.
