In the beautiful time between classes, in the corridor of the teaching building, students gather in twos and threes, and what is swaying is the light of the sun and the shadow of the camphor trees.

Dai Yujue was speechless. With his grades, it would be difficult for him to get into college, let alone a prestigious school.

After Xu Lingchu spoke angrily, he didn't have much to say to Dai Yujue. After speaking, he turned around and left. After saying this, he said goodbye with a cool and decisive manner.

Before leaving, she glanced at Li Xuan and Zhou Tian and smiled slowly and silently. For some reason, Li Xuan saw the provocation.

To be honest, her smiling eyes are quite beautiful, her clear and sharp eyes have a strong energy in them.

Li Xuan felt that some people may be born with certain beautiful qualities that others cannot learn, just like her smile at this moment, just like Li Xuan spends more time looking in the mirror after taking a shower. To put it simply,

If you are beautiful, others will pay more attention to you, and you will be rewarded by God.

Zhou Tian touched Li Xuan with his arm and said, "How is it? Is the real person okay?"

Li Xuan admitted, "It's okay."

Looks better in person than in photos.

But it has nothing to do with him.

Li Xuan has not thought about falling in love yet, nor does he want to get involved in the fights among high school students. The gags are interesting, but they can only be used as entertainment.

…

…

After explaining the test paper and ranking by year, that's it for the monthly exam this time. Campus life is so colorful. In addition to being worried about top students, students quickly forget about the exam.

The only remaining meaning of the monthly exam is probably to allow students to get on the right track in high school life and to encourage them to work hard and strive for success.

The days passed silently.

Because of Li Xuan's outstanding performance in the monthly exam, not only Zhao Dongming paid attention to Li Xuan, but also the teachers of other science subjects, especially Li Xuan's performance in class.

Li Xuan is not the type who listens completely carefully in class. For example, in physics class, better students take the textbook and listen carefully. However, Li Xuan is completely different. He will read reference books that summarize and even take the "Five-Year College Entrance Exam Three-Year Simulation"

》Brush up the questions.

It doesn't look like a freshman in high school, but like a senior in high school reviewing.

However, when the teachers got emotional about this and actually checked Li Xuan's learning progress, Li Xuan was shocked. It seemed that not only mathematics, but also Li Xuan's science subjects such as physics and chemistry were ahead of schedule, and he was able to successfully complete the college entrance examination papers.

extent.

Needless to say, there is no need to talk about English and Chinese. Li Xuan has been reading similar extracurricular books in class, saying that it is to expand his reading capacity.

This made it impossible for teachers of other subjects to treat Li Xuan with common sense, and could only let Li Xuan act randomly.

In the office, Li Xuan's teachers came to Zhao Dongming and talked about Li Xuan very much.

Li Xuan's performance was talked about by them.

"Teacher Zhao, you may not believe it, but Li Xuan has already studied high school chemistry by himself. It's not that he is not serious in class, he is just doing his own thing seriously instead of listening to my class."

"Who taught Li Xuan's physics? Why could he do the physics college entrance examination papers when I asked him to do it? I even found out that he did well on the science comprehensive examination papers for the college entrance examination?"

"As Li Xuan's biology teacher, I was very helpless. Li Xuan always didn't listen carefully in class. I was still angry at the time. But when he gave me the exercise book he was going to write this semester and wrote it all at once, he asked me if he could do it in the future.

When I don't have to check his homework, I have no choice."

"This is a bit amazing, isn't it? Why should I go to high school for three years? I can just take the college entrance examination next year."

Listening to other teachers' complaints one after another, Zhao Dongming became more and more convinced that Li Xuan had a superior IQ. Otherwise, how could he have become so famous? He obviously did so poorly in the high school entrance examination, but he got the highest score in science in his year when he entered high school.

There is an exercise book for each subject, and Li Xuan finished them all in more than a month. Not to mention how fast Li Xuan writes the questions, even if he writes fast, it will definitely take a lot of time, but Li Xuan completed it.

It can be seen that Li Xuan is not only smart, but also works as hard as anyone else these days.

In his opinion, Li Xuan was born to compete, and he even considered suspending classes so that Li Xuan could concentrate on the competition.

How could Zhao Dongming not like such a conscious and smart student?

Zhao Dongming often called Li Xuan to the office and tutored Xiaozao alone. High school mathematics was already difficult for Li Xuan, and he spent most of his time discussing the content of the competition with Li Xuan.

Not a professor, but a discussion.

Mathematics competition questions are very technical and have nothing to do with the amount of knowledge. Even if he has studied advanced mathematics, he can only be blind when he encounters very technical questions. Sometimes Li Xuan can give very clever answers to the answers that he cannot think of.

explanation.

Competition questions are like this. They don't do the questions often, and their problem-solving skills are not even as good as those of students. A mathematics teacher like him, who is not well-known in the country, plays more of a guidance and supervision role. Zhao Dongming still has some doubts about this.

These days, a document came from above, which was about the registration notice for the Chaoyang Cup National Mathematics Competition. After Zhao Dongming received the document, he called Li Xuan to the office as soon as possible.

Looking at Li Xuan who was confused, Zhao Dongming explained: "Li Xuan, there is a registration for the Chaoyang Cup National Mathematics Competition recently. According to the exam syllabus, it is mainly for sophomores in high school. However, I carefully studied the difficulty of the test papers in previous years.

, I feel that you have hope of getting a ranking, so the teacher will help you register first. There are still a few months left for the first test, so you should prepare well when you go back."

Li Xuan was stunned for a moment and nodded, "Okay, but Teacher Zhao, will I be the only one to participate in the first year of high school?"

"No, I plan to let all the students in the mathematics competition group participate, just as a practice and to feel the competition atmosphere in advance. But I feel that you and Liang Zhihui are the only two who are likely to win the prize. Among them, you are the most promising, so I will tell you first.

Say something to you."

Zhao Dongming has always had great expectations for Li Xuan.

This time the Chaoyang Cup is mainly open to high school sophomores. All senior high school students can participate. Only students from the competition group in the first year of high school will sign up. To get the ranking, you must have mastered the mathematics knowledge points of the first semester of high school and sophomore year. In the competition group of senior high school students,

There are still some people who do not meet this requirement.

Li Xuan understood, "Teacher, I will work hard."

Zhao Dongming admired Li Xuan sincerely, "Li Xuan, teacher, it seems that you have been specializing in plane geometry recently?"

Li Xuan took out his notebook and usually communicated with Zhao Dongming when he had questions. "Teacher Zhao, I mainly wrote test questions related to Menelaus's theorem and Ceva's theorem this week. I feel that I have gained a lot. These are my notes."

Menelaus's theorem and Ceva's theorem are commonly used theorems in ordinary geometry tests, and are powerful tools for proving collinearity and common points.

Li Xuan specially prepares a notebook to record the exercises he has done, for fear that he will forget his mistakes. Li Xuan has principles. It is not a matter of lack of knowledge. He must do the exercises by himself without looking at the answers.

Learning plane geometry will make people realize that mathematics is beautiful, or in other words, Euclidean geometry is beautiful. What can no longer be proved are the basic axioms, and then theorems are derived from the axioms, which initially demonstrates the logic of the establishment of the modern scientific building.

Zhao Dongming opened Li Xuan's notebook, lowered his head, and read for a while, "Circular Power Theorem, Radical Axis Theorem, Ptolemy's Theorem, Stewart's Theorem, Simson's Theorem, Esmodel's Theorem, Triangle Five Centers

The nature of...the test questions are divided into categories. Li Xuan, you summarized it very well."

There is only one person in the entire mathematics competition group who is as serious as Li Xuan.

Zhao Dongming was satisfied, with a smile on his face, "You don't need to remember too many theorems, and you don't need to memorize them specially. You need to analyze your ideas more. This Chaoyang Cup Mathematics Competition is naturally not as important and difficult as the high school national mathematics competition, such as plane geometry.

You won’t be tested too much on some of the content. Your focus this month may be on the relationship between sequence and function, the conversion of half-angle formulas of trigonometric functions, and the basics of sequence solid geometry. The teacher has found simulation questions for you from previous years. You can do some of them first.
