Xueba, I beg you to go and escort him quickly!

"Broken! The mentality has completely collapsed!"

"In my examination room, there were cries one after another..."

Crash to the extreme!

"Too helpless!"

"Oh no, it's despair! Despair is extreme!"

He Junfei's eyes stared straight, and he was in a daze.

"What's the matter? What's the matter with you, classmate?"

"Everyone says it's difficult! So don't burden yourself too much!"

"We all find it difficult!"

"If you can't help it, just cry!"

Some classmates persuaded.

"If you find it difficult alone, it's okay, but if everyone finds it difficult, it's all the same..."

He Junfei, "No, no, you don't understand!"

"Why don't we understand?"

Everyone looked sideways and looked over.

He Junfei frowned, with a look of helplessness on his face, "Can you really understand the despair you felt when you were asked by your neighbor and broke down and wanted to cry?"

My neighbor...?

Everyone was puzzled, "You said your neighbor is a university professor? Is it a teacher from one of those prestigious schools?"

He Junfei, "No! He's not a professor, he's just like us! They're both high school sophomores!"

They are all sophomores!

Sophomore!

student!

As soon as these keywords came out, the car became instantly quiet.

Even the two teachers leading the team twitched their eyes, "Student He Junfei, what do you mean...?"

There are more than a dozen cities in this province!

Every city has students to participate in the competition!

They can't understand the things in their own city, let alone understand other cities.

Xu Heng is currently quite famous in the city, but outside the city, few people know about it.

"???"

He Junfei took a deep breath, "You heard me right! My neighbor is the same age as me, but he is not a candidate for this Mathematical Olympiad, he is the winner!"

"It's the classmate of the classmate sitting next to me, and the same table."

Yang Kaixuan was also extremely serious at this time, "His name is Xu Heng... Maybe you don't know this person, but he got full marks in all subjects in two exams, and was invited by the country to participate in the ancient poetry revision meeting..."

Xu Heng?

Everyone looked at each other.

"This name is somewhat familiar..."

"I remembered! Is he the judge of the poetry competition? That person is also a high school student! It is said that he is from our province!"

Yang Kaixuan nodded, "That's right! It's him! It's him!"

"At the beginning, he should have come to participate in this competition, but he refused. However, Peking University came and thought that the professor of the Department of Mathematics invited him away half a month ago!"

"At that time, it was said that he was invited to join the test paper team to produce test papers for this exam!"

Many students panicked, "Wait a minute! There seem to be many loopholes in what you said!"

"What is a full score in all subjects? Is it a full score in mathematics? Or is it a full score...?"

Yang Kaixuan and He Junfei seriously emphasized, "All subjects! All subjects are full marks!"

Yang Kaixuan also said, "His perfect score is because there are only so many scores in the test paper!"

"Besides, he handed in every test in advance!"

"He is the number one in the city for the mid-term entrance exam! His composition has been circulated wildly on the Internet, you should have seen it? That classical Chinese composition!"

"Classical Chinese text translated and annotated by Professor Wu Liubai of Jingyun University!"

"Later, Professor Wu Liubai also came to our school several times to look for him!"

Jingyun University is the best university in the province!

Everyone here knows it.

The two teachers also heard about Wu Liubai.

"It's just... such an excellent student, such an excellent student in literature, how could he have something to do with mathematics."

Yang Kaixuan, "Didn't I just say that? He has full marks in all subjects, and he doesn't favor subjects!"

"Oh, I'm sorry, I didn't say the reason why he refused to participate in the competition... The reason why Xu Heng didn't come to participate in this competition is because he thought it was too simple..."

too!simple!one!!

"Impossible! How is this possible! How can there be such a person!"

"If there is, your school and the city will not try to get him to participate in the competition?"

Yang Kaixuan, "I'm not sure about that! But he is indeed different from ordinary people like us!"

Everyone, "!!!"

Those of us who can participate in the Olympiad are ordinary people?

Dissatisfied!

You guys don't speak right!

Yang Kaixuan, "He never listens in class, but he knows all the questions I ask, and he can give different ideas for solving them."

"Stop talking! There are too many incredible things about him! I can't finish it in a while!"

The students are getting more and more depressed!

The exam has made them very speechless and uncomfortable!

Now here comes another person who is so awesome!

And this person is also the one who passed the exam!

Depend on! ! !

"No matter how you say it, you can't verify it! Anyway, he didn't come to participate in the competition!"

· · · · · · · · · · · · · · · · · · · · · · · · · · ·????????????????

Yang Kaixuan, "You...!"

"I think it shouldn't be difficult for you to ask him a question! Why don't you ask me?"

Yang Kaixuan's forehead was throbbing with veins, "You are humiliating yourself!"

There are also materials and notes brought by Yang Kaixuan in the car.

He took it out and opened a page at random.

"Look! Just this question!"

topic:

定义在R上的函数f（x）满足f（1）=2，且对任意的x∈R，都有f（x）＜1/2，则不等式f（log2x）＞（log2x+3）/2，的解集为多少？

Seeing this question, the classmate laughed.

He handed the question to the other students, and everyone smiled and shook their heads.

Yang Kaixuan, "Xu Heng can give the answer within 1 minute, can you?"

"Xu Heng's problem-solving ideas, I can guarantee that you have never seen it before!"

"If you don't believe me, you can ask the two teachers to change the value of the question type. I will answer according to Xu Heng's method. I must be much faster than you!"

Yang Kaixuan's absolute belief and admiration for Xu Heng!

"Is it that difficult for some people to admit that other students are excellent?"

Yang Kaixuan slammed the ground loudly, and the corner of the student's eyes twitched, "Compare!"

The teacher looks at the questions, makes changes on the basis of them, and presents the questions in front of everyone.

"If you are interested, everyone will give it a try!"

"Paper and pen, everyone has it anyway!"

Some people have already started to answer the question, and some people are so confused that they don't even bother to read this question.

The dissatisfied classmate gritted his teeth and disdained Yang Kaixuan even more.

1 minutes……

2 minutes……

He's still digging his head in.

......................................

Yang Kaixuan, "Teacher, do the math, is the answer 0<x<4?"

One of the two teachers is also counting!

After correcting the question, he also began to answer the question.

Unexpectedly, Yang Kaixuan had already given the answer.

"This... you wait! You wait a moment! Please wait a moment!"

It took the teacher more than a minute before he raised his head. He had a look of disbelief, "Hiss... yes! That's the answer!"

And the dissatisfied classmate hasn't figured it out yet!

In fact, when Yang Kaixuan reported the answer, his mentality had already collapsed!

Depend on! ! !

The corners of his eyes twitched violently, and the veins on his forehead twitched violently.

The teacher looked at Yang Kaixuan, "Student Yang, can you share your problem-solving process?"

Yang Kaixuan spoke with a loud voice.

"This question can lead to g(x)=..."

concise!

understand!

Many people understand!

One of the teachers' eyes lit up and he patted his thigh.

"Absolutely!"

Yang Kaixuan, "I learned all this from Xu Heng!"

"Oh, if you still don't believe me, you can take a look at pages 7 to 11 of my notes! I think teachers should be familiar with that question!"

"This is the final question of the college entrance examination in a certain province many years ago! The average score of 30 candidates!"

This question is very famous in the mathematics circle!

"There are several solutions to the answer alone, and I sorted it out based on what Xu Heng said!"

"So far, there are only complicated and complicated standard answers on the Internet!"

"After all, the question is simply incomprehensible, and no one is willing to solve this question! Teachers don't know how to talk about the question!"
