Back in high school, I attacked my rival

"You don't have to explain it in such detail, it's too simple, I can understand it at a glance," Jie Qingyang pointed to the information book, and beeped dissatisfied.

After he finished speaking, he felt a chill in the side.

"No, I want to say that I'm not as stupid as you think. You don't need to explain to me what a rational number is over and over again, really." He blinked and looked at He Zhixiu sincerely.

"Why do you do so many stupid things if you're not stupid?"

Jie Qingyang couldn't refute this, so he lowered his head to read the book again, "Let's say it again."

"Compulsory one

Chapter 1 is very basic, and the basic part should be done well.But seeing that you are really smart, let's skip over and talk about the function part. With slender fingers, He Zhixiu held the pen holder and randomly scratched it on the white draft paper. Several common function formulas floated on the paper.

"You talk about their definitions, properties, domains, and value ranges, draw their images, and analyze their characteristics."

Jie Qingyang pointed to the first function, and said without hesitation: "The domain of the exponential function is R, and the range of the sum is from zero to positive infinity." He also took a pen to draw a few strokes under the exponential function that He Zhixiu just wrote, "This image is in the case that a is greater than 0 and less than one. At this time, it is a decreasing function on R; when a is greater than 0, it is an increasing function on R. This function is unbounded, infinitely tends to the X axis, and Never intersect."

"I have to add a few properties of it, it passes through a fixed point (0, 1), neither odd nor even."

He Zhixiu: "So clear."

Jie Qingyang: "I have passed the compulsory one myself, otherwise my monthly exam score of 80 would not be in vain."

He Zhixiu acted like you didn't say earlier: "You can see it for yourself?"

"It's not a difficult question. If it's too difficult, I won't know it for a while, but you're right. It's important to lay the foundation. All difficult questions are inseparable from the foundation. So, Mr. He, please tell me." , from the beginning of the compulsory course, I will listen carefully." Jie Qingyang held his cheeks in both hands and tilted his head.

His words are true, He Zhixiu's voice is pleasant, his tone is slow and expresses deep concern, and the person who concentrates is the most charming.

He Zhixiu rolled his eyes, his heart softened by his cute and obedient appearance, he stretched out his hand to touch Jie Qingyang's face, "This is just like a child."

"He's just a baby."

He Zhixiu withdrew his hand, repeated "baby" in a low voice, and the corners of his mouth raised for two seconds uncontrollably, before it was fleeting, he turned serious and said, "Let's start."

"Okay, Teacher He."

The two of them stayed in the study room until around twelve o'clock to stop today's study. Jie Qingyang was not sleepy at all, and even felt that he could listen to it all night.He loves He Zhixiu's lectures so much, they are meticulous and gentle, as if lying in cotton.

But He Zhixiu's morning self-study the next day was also his last morning self-study in Nangao, and the internship period was coming to an end soon.

What's more, Jie Qingyang had to be earlier than him, and he had to do exercises.

"Mr. He, I listened to your class today. The Chinese teacher is different. The words used in the math class are so beautiful and accurate, and they explain it to me from different aspects. I suddenly understood," Jie Qingyang stretched. He raised his head and hung it on the chair, "I got it all together in one go."

He Zhixiu was tidying up the information books and drafts on the table, "Why don't you say that you are enlightened?"

"What does it mean to be enlightened?"

"It used to instill wisdom in the middle finger of Buddhism to make people fully awakened. Now it is a metaphor that I have listened to brilliant and brilliant opinions and have been greatly inspired."

"It's really a little bit." He Zhixiu got up after tidying up, "It's past twelve, go to sleep."

Mentioning this, Jie Qingyang's eyes glowed with excitement, he lost all sleepiness, and immediately went to open the door, a fluffy thing quickly passed him and wrapped around He Zhixiu's feet.

"Oh, it ignored me." Jie Qingyang died of envy, "I just took a bath with me, did you forget our happy time in a blink of an eye?"

He Zhixiu picked it up with one hand, walked over, and stuffed it into Jie Qingyang's arms, "Happiness is what I strive for."

"You want to enlighten me again." Playing with a dog, he never forgets to preach.

He Zhixiu couldn't help laughing, he didn't expect Jie Qingyang to use it so flexibly, his smile couldn't stop smiling.

"You can be deaf to me."

Jie Qingyang was teasing the dog, and when he heard this sentence, he frowned and began to study hard, "What does it mean to be deaf?"

"It used to mean that the sound is so loud that the deaf can hear it, but now it is used as a metaphor, and the words wake up the numb and confused." He Zhixiu is like a dictionary, omniscient.

Jie Qingyang was a little unhappy, and murmured: "I'm not a stupid person."

He Zhixiu was too sleepy, so he didn't answer his words, and went into the bedroom first, not forgetting to remind, "Put the dog in the cage on the right side of the living room, and cover it with a cage cloth. It's too late, don't play with the dog!"

"Yeah." Jie Qingyang went into the bedroom after following the instructions correctly.

He stood at the head of the bed, hesitating whether to sleep with He Zhixiu or each other?
