Chapter 40 National Set Test and Extra Points
"Brother Chuan, is the training intensity at Wu Jing also so high?"
In the cafeteria, the round-faced Lu Tianrui asked curiously while picking up the 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. He could easily solve every difficult question after consolidating it in the afternoon.
Xu Chuan said with a smile: "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's just enough to 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 basic things.
However, this method of explanation is extremely suitable for him.
And in his opinion, this training method is actually quite good.
For these contestants who can enter the National Jiji, the basic things have already been learned, but it does not mean that these basic things do not need to be learned again.
On the contrary, the more basic the knowledge, the more important it is.
Just as all mathematics evolves from 1+1=2, so do the basic formulas and knowledge. They are the beams and roads of complex mathematical problems.
All mathematical problems are solved by deriving changes step by step.
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.
You shouldn't ask this pervert!
After dinner, it was so-called testing time.
One test paper, three questions, two hours, the paper will be collected on time when the time is up. The content of the test paper is the knowledge points explained today.
The score on this test paper will be one of the keys to whether a National Ji member can join the national team.
Not all students can endure the high-intensity training, especially those who are entering the national competition for the first time.
Early the next morning, another student collapsed with a high fever of 38.9 degrees and was rushed to the hospital with severe fluids.
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.
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 compete with the national team.
Seeing all this, Xu Chuan sighed. Those who engage in scientific research must still have a good body.
Let’s start running from three kilometers to five kilometers in the morning tomorrow.
The first day is about geometry, the second day is about functions, and the third day is about functions again.
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. The style is completely different from the first and second days.
Both the geometry professor on the first day and the function 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.
But what he talked about was not the basics, but the transformation between the difficult function application solution and the relationship between Dirichlet functions.
This left many trainees confused for a while.
Especially the senior high school students who had already joined the training team last year, they were even more confused and didn't understand what the routine was this year.
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.
But today's course is very strange, in-depth knowledge of the Dirichlet function in college high school mathematics.
It is true that the Dirichlet function is a content in high school, but it is not studied in depth in high school.
Only after you study advanced mathematics in college will the Dirichlet function be taken seriously. In previous years, IMO competition questions generally did not test this area.
Not only the explanations during the day, but also the test questions in the evening were particularly interesting.
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 will not be included in the total test score of the National Comprehensive Study Group. However, those who can complete these three math questions within fifteen minutes will receive an extra five points, and those who can complete these three questions within half an hour will receive an additional five points." Students who answer the question will receive an additional three points.”
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.
You must know that the total score of the test paper every night is only fifteen points, and 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.
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.
Today’s course was not originally part of the national training. Most of the knowledge and topics explained were dismantled from the previous information warfare decryption of encrypted messages. The purpose was to train and select students with talents in this area, focusing on nourish.
Guoji's training was extended for ten days for this reason.
Among this group of students, the one he looked forward to the most was Xu Chuan.
I don’t know how this player who got perfect scores in last year’s CMO will perform.
In the classroom, Xu Chuan has already received tonight's test questions.
The three questions are all transformation functions of the Dirichlet function, which are quite difficult.
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 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.
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.
There is a time limit after all.
But it was not difficult for him to solve these three big questions in fifteen minutes, and it didn't even take ten minutes.
