Chapter 40 National Collection Test and Extra Points
Chapter 40 National Assembly Test and Extra Points
"Brother Chuan, are the training intensity at Wu Jing also so high?"
In the cafeteria, the round-faced Lu Tianrui asked curiously while picking up some food.
He had been observing all day today, but he found that Xu Chuan didn't look strange at all. It was as if such an intense training session didn't exist at all. After consolidating in the afternoon, he could easily solve every difficult question.
Xu Chuan laughed and said: "The intensity of the Wu Jing National Games is not as high as that here. There are often experiments done there, so there is more time to rest."
"Then why do I feel that nothing is wrong with you? Isn't this intensity enough?"
Lu Tianrui licked his lips and asked.
"It's okay. It doesn't feel very difficult. It can just consolidate some basic knowledge."
Xu Chuan replied that although the intensity of today's training camp was high, the geometry knowledge explained was not very advanced, but rather some basic things.
However, this method of explanation is extremely suitable for him.
You shouldn't ask this pervert!
As soon as these words came out, the classroom became a little noisy, and everyone was gearing up to meet the challenge!
Five extra points!
This is very important for the members of the training team.
On the podium, Zhang Weiping distributed the test papers in his hands and continued:
"There is no time limit for tonight's test, and the test scores are not included in the total test score of the National Congress. However, those who can complete these three math questions within fifteen minutes will receive an additional five-point reward, and those who can complete these three math questions within half an hour will receive an additional five points."
Students who answered the question will receive an additional three points."
But what he talked about was not the basics, but the transformation between the difficult function application solution and the relationship between Dirichlet functions.
I don’t know how this player who got perfect scores in last year’s CMO will perform.
It is true that the Dirichlet function is a content in high school, but it is not studied in depth in high school.
The score on this test paper will be one of the keys to whether a National Group member can join the national team.
Especially the senior high school students who had already joined the training team last year, they are even more confused and don't understand what the routine is this year.
Not only the explanations during the day, but also the test questions in the evening were particularly interesting.
Among this group of students, the one he looked forward to the most was Xu Chuan.
After distributing the test papers, Academician Zhang Weiping held a thermos cup and sipped tea while looking nervously and expectantly at the students doing the questions in the classroom.
Let’s start running from three kilometers to five kilometers in the morning tomorrow.
The doctor said that he had a febrile convulsion caused by excessive stress and mental exertion, and that he needed to rest for at least a week.
Normally, the function part should start from the basics, advance from the basics, and consolidate high school knowledge points. This was the case last year.
In the classroom, Xu Chuan has already received tonight's test questions.
You must know that the total score of the test paper every night is only fifteen points. The difficulty of the questions is quite high. Not everyone can get full marks every day. Maybe with these five points more, they can join the national team.
All mathematical problems are solved by deriving changes step by step.
To put it simply, the brain, the CPU, cannot handle the overload operation for a long time and directly shuts down.
After a week's rest, it can be said that this student has no chance to participate in the national team.
This left many trainees confused for a while.
Just as all mathematics evolves from 1+1=2, so do those basic formulas and knowledge. They are the beams and roads of complex mathematical problems.
The three questions are all transformation functions of the Dirichlet function, which are quite difficult.
Both the geometry professor on the first day and the functions teacher on the second day wanted to finish reading the book in one day, but on the third day, Academician Zhang's lecture was slow and slow, neither fast nor slow.
Seeing all this, Xu Chuan sighed. Those who engage in scientific research must still have a good body.
Guoji's training was extended for ten days for this reason.
But today's course is very strange. It goes deep into the knowledge of Dirichlet function in college high school mathematics.
The style is completely different from the first and second days.
Only after you have studied advanced mathematics in college will the Dirichlet function be taken seriously. In previous years, IMO competition questions generally did not test this area.
The first question is combined with the composite function to find the number of roots; the second question is combined with the conic section to verify the light reflection point; the third question is combined with the sequence to find
"This question is quite interesting, but the bonus points may not be so easy to get."
Xu Chuan looked at the questions in his hand with great interest. Although the three questions were of different categories, they seemed to be taken from a certain big question, because some of the values in the questions were not modified.
Hearing this answer, the corner of Lu Tianrui's mouth twitched. He looked at Xu Chuan with a resentful look and then buried his head in eating. He didn't want to talk anymore and was hit again.
After dinner, it's so-called test time.
Not all students can endure the high-intensity training, especially those who enter the National System for the first time.
One test paper, three questions, two hours, and the papers will be collected on time when the time is up. The content of the test paper is the knowledge points explained today.
And in his opinion, this training method is actually quite good.
Early the next morning, another student collapsed with a fever of 38.9 degrees and was rushed to the hospital with severe fluids.
The main lecturer on the morning of the third day was Academician Zhang Weiping, a director of the Mathematics Society. An academician of the Academy of Sciences came to give a lecture to a group of high school students. It must be said that IMO is still very valued in China.
For these contestants who can enter the National System, the basic things have already been learned, but it does not mean that these basic things do not need to be learned again.
The first day is about geometry, the second day is about functions, and the third day is about functions again.
Today’s course was not originally part of the national training program. Most of the knowledge and topics explained were dismantled from the previous information warfare decryption of encrypted messages. The purpose is to train and select students with talents in this area, focusing on
nourish.
On the contrary, the more basic the knowledge, the higher its importance.
Judging from the difficulty of the questions, most of the students from Guoji can do it, but if they want to get the bonus points, maybe only a few can do it.
After all, there is a time limit.
But it was not difficult for him to solve these three big questions in fifteen minutes, and it didn't even take ten minutes.
