Chapter 4 Odd Functions? Even functions?

"Lu Yao, it's time to get up. www.biquge.info it's only the first day of school today, so you don't want to be late. You see, Lu Yuan is already having breakfast. The sound of An's mother urging An Luyao to get up regularly every day came from the bedroom.

When it comes to it, never get in bed.

Brush your teeth and wash your face.

"Sister, do you want me to wait for you?"

"Huh?" Hearing her younger brother An Luyuan calling her, she quickly spit out the foam in her mouth, "No need, you still take the bus to school, just get close to the first middle school and let me ride a bicycle." ”

"Then I'll go first."

"Go ahead, be careful on the road.

Coming out of the bathroom, she put on her big glasses, and ate a few mouthfuls of porridge indiscriminately, and she was ready to go.

The morning sun is not too scorching, autumn has not yet arrived, and there is still a feeling of boredom in the air. Riding on the bicycle and letting the breeze pass by his ears, An Luyao hummed a self-composed tune:

Our time is the wind passing by our ears

Actually, there was no result

The world has you passing through

Youth has never doubted

Our freedom is said by the rain in sight

Actually, there is no fault

The future is not known

May fate live up to you and me

Lalalala......

"Yo, you're in such a good mood early in the morning?" The boy's laughter sounded behind her with a wheez.

"Zuo Jue? Good morning! An Luyao didn't know why, he was like a bird breaking free from the cage, and he was indescribably happy.

"Don't look back, stay safe." Zuo Jue reminded her on the side, as if every time he met this girl, his mood would get better inexplicably. The smile on the corner of his mouth is expanding endlessly.

Short hair, cheeks with a bit of baby fat, big round eyes. Jeans, a bright yellow T-shirt, and a black mountain bike like herself, this is her.

An Luyao parked the car and locked it.

"An Luyao, do you know that I am at the table before and after you?" Zuo Jue walked towards her.

"Huh?" She was momentarily confused.

"You don't seem to care about anything."

Is it because you don't care? It turns out that you are just like that person.

"No, I just didn't pay attention, I'm sorry. Walk together? It's been a long time since I'm late, but the air is so good in the morning, let's go to class. ”

"You go first, I'...... Wait a minute. ”

"Well, I'll go first." An Luyao was a little puzzled, who are you waiting for so early?

Of course, this doubt was quickly forgotten in math class.

"Lu Yao, do you understand?" Jiang Ruili's current state is the same as An Luyao's, so much so that her gaze still stops on the blackboard.

"Students, how do you say this f(x), you can think of it as y= in junior high school, but this completely ignores the definition of mathematics, of course, I talked about odd functions, even functions, this read the book, and you can understand it yourself. Okay, let's take a look at the college entrance examination question. ”

Old man Qian, who teaches mathematics, said to himself, "Are the experimental classes of No. 1 Middle School so genius? An Luyao muttered more than once in his heart, although it was a miracle that he could enter a middle school, but the span of this class was too big, and it was a college entrance examination question as soon as it came up. She looked at the classmates around her again, okay, An Luyao comforted herself like this, there must be someone who is as stunned as me, there must be.

Yes, for example, Li Qingchen and Master Li.

Looking at the large number of questions on the workbook, Li Xiaoye looked around and saw An Luyao's booklet, which was also blank.

"This An Luyao, is it also the experimental class that I entered with **** luck?" He thought silently. At the same time, Zuo Jue had already solved the last question smoothly. Li Qingchen looked at him quietly from the side, because he had been accustomed to Zuo Jue's essence of being a scholar since he was a child.

"Zuo Jue, tell me about the following physical education class. At this speed of Old Man Qian, do you think we are all going to Tsinghua University? He whispered to Zuo Jue. You Jia and Qin Hong in the front, and Xiang Yujin in the back are all silently calculating the last question, obviously they were previewed last night, but it is still a little difficult to listen to the math teacher today, is this really the difference in high school?

An Luyao himself is not cold to mathematics, and now he can only look at the sky with two eyes, so let's watch it after class.

If there is one of the best regulations, it should be that physical education class gives students the greatest degree of freedom, although there is no special reason why they cannot be absent, but An Luyao and Li Qingchen have a very special reason.

"You read the book first and understand the basic concepts." Zuo Jue was talking to Li Qingchen, An Luyao happened to have just sent her history homework over, and she was bombarded with a bunch of math and physics problems, and she was about to take a look again in the classroom. Then, I met those two "living treasures".

"Eh, An Luyao, are you also here to read the book?" When Li Qingchen saw her, he was as excited as if he had seen the allies. Zuo Jue on the side looked at his funny appearance and laughed again.

"Do you want to be together, Lu Yao? With this kid, let's go over the parity function and the physical acceleration. ”

"That's right, Zuo Daxia is a real student." Li Qingchen vowed to sell his good brother.

"Actually, I can see for myself. Moreover, Su Qing has taught me a lot after class. "An Luyao always feels that it is not a good thing to trouble others.

"Su Qing, that guy will teach others homework?" Li Qingchen chattered again.

"It's okay, Lu Yao, let's take a look, if not, you can discuss it." Zuo Jue still ignored Li Qingchen.

"Then, I'll bother you."

"Come on, let's look at this question first."

"Hmm."

"Okay."

The two men replied in unison.

Odd Functions, Even Functions, Acceleration...... Some different elements are mixed in the feast of youth, like gifts from the years that follow, and simply do not take away any memories.

Large recess in the afternoon.

"Lu Yao, why didn't you go to physical education class today?" Su Qing took her arm and asked her leisurely.

"I'm looking at acceleration in the classroom, I'm not as smart as you, and I want to thank Zuo Jue." An Luyao turned around and gave Zuo Jue a big smile.

"It's okay, anyway, teaching one is also teaching, and two is also teaching. And ......" he said this, turning his gaze to Li Qingchen, who was "fighting to the death" with the chemical operation.

"Qingchen, this child, is probably hopeless." Zuo Jue covered his face.

"What do you mean I'm hopeless? Isn't it just math and physics? Zuo Jue, if you do this again, I won't make you breakfast! "He's also a temperamental person. Anything can question him, only the question of IQ, he refused, especially in front of Su Qing, looking at the two so-called "fat small" in front of him, Li Qingchen was really thinking, these two people were born to be other people's children who let their parents say! Zuo Jue is okay, after all, his home is not close, especially Su Qing.

"Look at the people, Su Qing took the first place again."

"Look at Su Qing's essay contest and it's the first prize again."

……

And now, Su Qing was looking at him with a sly expression.

"Okay, okay, my little Qingchen, can't I be wrong?" Zuo Jue put his arms around him, for the sake of breakfast - endure.

Zuo Jue's breakfast since elementary school has always been contracted by Li Qingchen because of that irresponsible woman. However, in the words of Zuo's father, he and Zuo's mother divorced by agreement, and there was no quarrel between them. Zuo Jue remembered that when the woman left, she was smiling, she touched his head and said lightly: "Zuo Jue will listen to his father in the future." Then, she ran to her scientific research career. At that time, he didn't know what the woman meant by this, but he felt that today's mother was not as cold as usual, and replied stupidly, "I will be obedient, Mom." "There were some things, things that only adults could understand, that he couldn't understand when he was only five years old. Later, in school, I met Li Qingchen, the boy who said that he would contract his breakfast when he was a student.

Therefore, although Zuo Jue is a day student, lunch and dinner are always eaten in school. Due to the ban on self-study in the middle of the night, no one dares to violate the ban that all students must participate in.

"I didn't expect Xiang Yujin to play basketball so well, it's a pity that you didn't watch it." As soon as You Jia came in, she hugged An Luyao.

"yes, yes, I'm stunned!" The girl named Qin Hong echoed, "Feints, dribbling, shooting outside the three-point line, it's amazing!" She gestured as she spoke, still immersed in the shock that Xiang Yujin brought to them.

"Really? Then I'll go with you next time. An Luyao gave You Jia a hug back.

"Xiang Yujin?" Su Qing accosted on the side, "Well, it's normal, his mother and my mother are good friends, wasn't the provincial team recruiting people some time ago?" I heard her mother say that if it weren't for Xiang Yujin's lack of interest and said that she would be inspired to take the Tsinghua exam, maybe he would be a member of it now. ”

"Su Qing, you know again." Li Qingchen stopped the fierce battle with the "chemical operation" and was skeptical of her.

"Of course I know, I'll tell you Qingchen, I also know that someone is still wetting the bed at the age of ten, and his confession to the little girl was rejected, and he is crying over there, and there is still ......"

"You're enough, aren't you? Su Qing, don't think that if you are my junior high school tablemate, I won't dare to do anything to you. Really, Master, Master wants to go out! ”

Seeing that everyone laughed and burst into tears, except for An Luyao, who just looked at him a little coldly, like the expression of the first meeting. Li Qingchen felt that his face was a little unbearable, and he ran out as soon as he slipped away.

"Is he usually so shy?" An Luyao asked Zuo Jue.

Shy, the word...... Well, I can't bear to hurt Qingchen anymore.

"yes, it's just a lot of talk." He looked her in the eye and replied softly.

An Lu Yao smiled at him, such a smile was never forgotten when Zuo Jue left City C.

This kind of gossip will naturally have a lot in the years to come. They are also a group of clear children with a bright future and an infinite future.
