Chapter 57 Excellent or Show?



Chapter 57 Excellent or Show?

Today's main class, only Xu Shaowen's Chinese class, is continuing to teach him the essence of answering questions.

For other subjects, as soon as class started, the teacher handed out the test papers for last night's mixed exam.

It was only one night after the test papers of the big mixed exam, all the grades were completed.

The first thing Chen Zhou received was mathematics, and he scored 94 points.

Because the number of questions is reduced, mathematics is a paper with a full score of 100.

The same is true for comprehensive science, the full score is only 200 points, 80 points for physics, 70 points for chemistry, and 50 points for biology.

Looking at this bright 94, Chen Zhou thought to himself, does this count as being excellent?
After all, in terms of score value, it also exceeded 90% of the full score.

Of course, he was just thinking about it, and he still knew it in his heart.

For an incomplete math test paper, it is impossible for the system to count him as achieving a small goal.

Chen Zhou turned the test paper to the end, looking at the final function question solved with advanced mathematics knowledge.

Wang Xuehui gave 14 points, out of [-] points, no deductions.

The corners of Chen Zhou's mouth curled up a bit, a little proudly.

Zhang Yifan noticed Chen Zhou's appearance, followed his gaze, and said strangely in his heart: "Isn't it just the last question that has been solved? As for it? This question is not difficult."

However, when Zhang Yifan carefully looked at the answer written by Chen Zhou in the last question, a series of question marks appeared in his mind: "What is this? Lagrange's mean value theorem? Who is Lagrange? How did he Can you do this? Is that right?"

On the podium, Wang Xuehui began to explain the topic, Zhang Yifan had to temporarily suppress his doubts and focus on listening.

When the get out of class was over, he immediately asked Chen Zhou, "Chen Zhou, what are you writing? What is this Lagrangian theorem? What is it? Can you do this?"

Chen Zhou was slightly taken aback, and glanced at him.

Just as he was thinking about how to explain it, Li Xiang heard Zhang Yifan's voice, turned around and asked, "Yifan, what are you talking about? What Lagrangian? Who used this theorem?"

Zhang Yifan pointed to Chen Zhou's test paper.

Li Xiang took Chen Zhou's paper and searched back and forth.

"The last question."

"Oh." Turning to the last question, Li Xiang became more and more surprised.

After finishing reading, he raised his head and looked at Chen Zhou, the admiration in his eyes became stronger.

"Why are you looking at me like that?" Chen Zhou felt goosebumps all over his body.

"Brother Chen, you are amazing!" Li Xiang continued excitedly, "I only knew that you were very good in Chinese and English before, but I didn't expect that, Brother Chen, you are also so good in math!"

Zhang Yifan was shocked by Li Xiang's exaggerated expression and tone, and couldn't help asking: "No, Li Xiang, what happened to Chen Zhou? What do you mean?"

At this time, Chen Haining also turned his head and looked at it curiously.

Li Xiang picked up Chen Zhou's test paper, put it in front of Zhang Yifan, pointed to the "Lagrangian median value theorem" written by Chen Zhou and the corresponding formula, and explained: "This theorem can only be learned after going to college. Mathematics knowledge. Generally, high school students don’t know it at all, let alone use it in solving problems. Moreover, if you use advanced mathematics knowledge to solve high school mathematics problems, you must ensure your proficiency in relevant knowledge, and you must not make mistakes at all. , otherwise there is no point."

"Fuck?!" After Zhang Yifan listened, he looked at Chen Zhou, then at Li Xiang, and asked, "Li Xiang, how do you know this?"

"I know this theorem as well, but I don't dare to use it, I'm not familiar with it, and I'm afraid of being wrong." After Li Xiang finished speaking, he took a deep look at Chen Zhou, his eyes full of admiration.

Zhang Yifan and Chen Haining looked at each other, and Chen Haining asked again: "No, according to what you said, this is not something we can understand at all, where did you learn it from?"

Li Xiang thought for a while and asked, "Does IMO know? Have you ever understood?"

Zhang Yifan and Chen Haining shook their heads.

Li Xiang asked again, "Then the National High School Mathematics Competition and the Chinese Mathematics Olympiad, do you know?"

The two nodded: "But what does this have to do with advanced mathematics?"

Chen Zhou also looked at Li Xiang with great interest, waiting for his explanation.

After all, Chen Zhou didn't know what the connection was.

Li Xiang continued: "The National High School Mathematics Competition is a relatively high-level mathematics competition in China's high school mathematics discipline. You can understand that it has a higher status than the mathematics competition organized by our own province in Anhui Province."

"Then, about 400 students who have achieved excellent results in this national competition will be eligible to participate in the Chinese Mathematical Olympiad organized by the Chinese Mathematical Society, also known as the CMO."

"Then, about 60 students with excellent results in the CMO can enter the national training team. After the selection of the training team, 6 top performers will enter the Chinese national team to participate in the International Mathematical Olympiad, that is, IMO."

Chen Haining couldn't help but interrupted: "It sounds very powerful, but what does this have to do with that theorem?"

"Don't worry." Li Xiang glanced at him and continued, "Why do I say this IMO, because the knowledge of advanced mathematics, which ordinary high school students are not exposed to, is very common knowledge among IMO contestants. They For the competition, I don’t know how many theorems of advanced mathematics I have learned in advance. The Lagrange median theorem used by Brother Chen is the knowledge that these contestants must master.”

"Anyway, except for the IMO players, I haven't seen a few who can fully use these theorems. Even if other people understand, they are not proficient in using them. Like me, they are half-baked. So, do you understand?"

After finishing speaking, Li Xiang looked at Chen Zhou with hot eyes.

Chen Haining and Zhang Yifan were a little slower, and then blurted out "Fuck!"

Dare to love, this is a contestant participating in the international competition?

Chen Zhou looked at the eyes of several people, he really didn't expect Li Xiang to say this, IMO players are highly regarded
After thinking for a while, Chen Zhou said: "Don't look at me like that, I really haven't participated in this IMO. These...I said I taught myself, do you believe me?"

Seeing the doubtful eyes of the three, Chen Zhou said again: "Uh, think about it, if I were an IMO player, would I still come here?"

This sentence reminded the three of them, and when they were about to question Chen Zhou again, the class bell rang.

The three had no choice but to give up temporarily and prepare for class.

Chen Zhou heard Chen Haining talking to Li Xiang in a low voice again.

"Li Xiang, is this IMO really that strong?"

Li Xiang: "If you still don't understand, you can go back tonight and look up the gold content of IMO."

Chen Haining asked again: "Then you are also an IMO player?"

"No, I am" Li Xiang paused before saying, "Preliminary contestant"

"Oh, that's okay. You and I are the same as Yifan." Chen Haining asked again, "Then tell me, is Brother Chen really an IMO player? But it doesn't look like that."

Li Xiang replied: "Is this important? Do you think it matters whether he is an IMO player if he can learn these theorems of advanced mathematics and use them proficiently?"

"Besides, why did I say to use this formula to solve the problem? If you make a mistake, you will lose a point. In fact, this is the protection of ordinary students in the college entrance examination. Not everyone has access to this knowledge. For the sake of fairness, we have to restrict You can’t use it indiscriminately. If you want to use it, you have to master it proficiently, otherwise you have to do the questions honestly. You have to know that mastering it proficiently and making no mistakes is much more difficult than learning this theorem..." Li Xiang said this, and then He turned his head and glanced at Chen Zhou.

Chen Haining was taken aback for a moment, and then suddenly realized: "That's right. It seems that Brother Chen has completely left us behind. I used to think that Brother Chen was only good at Chinese, but later I found out that his English is also very good. Unexpectedly, his mathematics It is better than Chinese and English, and it goes directly to the higher mathematics of the university."

Chen Zhou: "."
