Looking at the dead fish face of the head teacher, I really couldn't feel better, but fortunately, Li Jiajia was in front of me. Li Jiajia's hand has been removed from the gauze, and there is an obvious mark on the back of the hand, but the swelling is no longer visible to the naked eye.

"Are you okay with your hands?"

"It's okay, just write a little slower."

"That's good."

Li Jiajia didn't look back, so I didn't bother her. I started my own review, in fact, I really wanted to review with Li Jiajia, but she didn't take the initiative to ask me and I was embarrassed to look for her. I took out the chemistry book and reviewed it, although I have some prejudices about the head teacher, but my own learning is the first priority, and I still have this reason.

"By the way, what are you homeroom teachers teaching?" Li Jiajia suddenly turned her head and asked me.

"Chemistry!"

Li Jiajia turned around again with a sigh and changed the book, but I didn't see what it was. The atmosphere of evening self-study is not so tense, and it is even a little lively. And the head teacher kept his head down, ignoring the situation in the classroom. My classmates were all discussing it, and I was silently reading the book by myself, not even wanting to look up.

"How do you balance this equation?"

After waiting for so long, I finally waited for Li Jiajia to turn around, and my slightly depressed mood was liberated. Looking at the equation in front of her, it was relatively simple, and she wrote the answer directly.

"How?"

"First observe the change in valency, and then conserve the ............ according to the gain and loss of electrons"

Li Jiajia didn't seem to understand, and the little glasses looked at me and said, "I don't understand." ”

"Let's look at the valence first, you see that on the left it is a positive valence, and on the right it has become negative, is the valence reduced..............." I drew it for her while talking, Li Jiajia kept "um" on the side.

After I finished speaking, Li Jiajia looked at the workbook thoughtfully, and then supported her chin with her hand, but she forgot that her injury was not healed.

"Ahh

I couldn't help but laugh, and the voice was not small. The eyes of my classmates all looked at me, and it made me feel like I was committing a crime, and I didn't dare to look at them, so I just lowered my head and hid.

"Don't laugh, well... It hurts to death. ”

"Don't laugh, don't laugh."

"Huang Haiyu, if you don't learn yourself, don't influence others." I really don't want to bird him. He doesn't care if other people are so loud, why do they have a soft spot for me? I really don't understand why he is so prejudiced against me.

"Why do your homeroom teachers have such a big opinion of you?"

"How do I know? Maybe menopause has arrived. ”

"Yes, there are always a few days in a month."

"Why does this sound so awkward, what do you mean?" This was indeed a bit difficult to understand, but our homeroom teacher was a man, so he leaned over and asked. Li Jiajia's face turned red all of a sudden, and she quickly changed the topic: "Don't talk about him, tell me about it again." ”

Seeing her blushing, in fact, my heartbeat also accelerated, after all, it was the first time I had discussed this kind of topic in front of a girl. Li Jiajia diverted the topic, and I borrowed the slope to get off the donkey.

I thought that the teacher on duty would always be the homeroom teacher, but when I returned to the classroom, I saw their homeroom teacher. Now I'm happy, the eyesore is finally gone.

"What exam room are you in?"

"Four."

"Such a coincidence? I'm also in room four. ”

What a surprise it was!

"What seat are you?" I'm twelve. ”

"I'm on the twenty-one, it seems a little far."

I didn't hear what she said behind me, only a twenty-one. My mind was frantically calculating, but at this time my brain didn't seem to be very good, so I picked up a pen and drew it on paper.

Li Jiajia came over and asked me curiously, "What do you paint?" I didn't answer her and continued to paint.

"Great, you sit next to me."

"Really? Then I won't, and you'll have to tell me. ”

"Absolutely."

Of course, I agreed to this kind of good thing without hesitation, and the three days of exams were in the same classroom, and they sat side by side, and they were also together in the evening self-study.

Changing a teacher is actually much different from him, it's all the same decoration, what should everyone do or what they do, completely ignoring the existence of the teacher.
