The strong ones are all here, there are more than a hundred and ten people, most of them are high school juniors, and a few are high school sophomores.

This classroom can seat more than 50 people, first to come, first to sit, and then to stand.

Tong Yuanhong presided over the meeting, she said: "From now on, the new sheep competition team will be established, and I am your head coach Tong Yuanhong." These teachers around me are members of my team, Mr. Ou Yahai, who is in charge of mechanics theory. Mr. Dong Lei is responsible for the theory of heat. Ms. Kwong Meixia is responsible for the theory of electromagnetism. Mr. Yu Zhengyuan is in charge of optical theory. Teacher Li Bin and Teacher Chen Jie were in charge of the experiment. As the head coach, I was also in charge of modern physics. My team will stay with you until at least the end of October, and at most until July next year. In the next two months or nearly a year, hopefully we can get along. ”

Tong Yuanhong said this, there was a brief pause.

The students applauded sensibly and applauded thunderously.

Tong Yuanhong gave instructions: "Don't say much, the students who are standing, please move to the competition classroom next door, and our competition intensive training will start immediately." ”

More than 100 competition players were divided into two classrooms, and each team member received a copy of "Physics Competition Guidance in the Sheep (Book B)", and the competition coaches took turns to play, and each coach spoke for 90 minutes, and then replaced the next coach.

The training mode of the competition class is similar to the teaching mode of the college entrance examination class, and the mechanics, heat, electricity, magnetism, light, and modern physics of the competition class are similar to the language, mathematics, English, physics and chemistry of the college entrance examination class. The difference is that the competition class attaches more importance to experiments, and experiments occupy 30%~40% of the training time.

The ten students of the third and third classes were all in the No. 1 classroom of the competition, at half past five in the afternoon, Tong Yuanhong finished talking about some knowledge points of modern physics as planned, she said: "I know that some students have signed up for CMO, tomorrow is the preliminary round of CMO, students who have signed up for CMO can go, students who have not signed up for CMO go to dinner, and we will continue to talk about theory at half past six." ”

The students left the competition classroom quickly and orderly, Wu Zihan was holding on to the wall, he was weak, he was staggering, he was about to die.

Lan Jie picked up Wu Zihan and slowly moved towards the school gate.

"Zihan, I feel that your breath is unstable. ”

"The training intensity of the competition class is terrifying. ”

"It's only been a day of training, Zihan, you can't bear it?"

"The same force, the force of the competition class is very different from the force of other places, the force of the competition class is stronger, more deep, and more oppressive. The same is true of heat, electricity, magnetism, light, modern physics, I ...... I can't take it anymore. ”

"Zihan, you have to attend a physics cram school outside of school, you have to be at least half a year, right?"

"To tell the truth, any coach of our sheep competition team goes to an outside training institution as a lecturer, it must be a lecturer at the level of a training institution. ”

"Can I understand that our sheep competition team is more perverted than the training institutions outside?"

"Yes, more perverted. It's perverted, but it's really exciting!"

"Zihan, is it okay for you to participate in tomorrow's CMO in your current state?"

"I knew that I could be selected for the sheep competition team, I shouldn't have signed up for CMO, and my nutrition couldn't keep up. ”

"Are you going to participate in the CMO preliminary round tomorrow?"

"Then I have to go, I have been studying in the Olympiad class outside for more than half a year, and I have paid 20,000 thousands of tuition fees, and I am sorry for the money if I don't go to the CMO. Hey, people like us, if we don't add weight outside of class, it is difficult to be selected for the sheep competition team, even if we spend money to increase the code, we may not be selected. In today's society, where money is spent but problems cannot be solved, I am afraid that there are only middle school campuses left. In our sheep, solving problems depends mainly on IQ. ”

"Zihan, why did you suddenly become so pessimistic?"

"I paid more than 30,000 yuan in the physics cram school outside and studied for more than half a year, but this time I only scored more than 130 points in the preliminary competition. Brother Jie, you don't seem to have reported to an extracurricular class, right?"

"I can't help it, my family is poor. ”

"Vomit...... Vomit!"

"Zihan, you are working too hard, learn to vomit!

......

On the morning of September 14th, Lan Jie came to the Yueshan District Test Center again, he was the first time to participate in the CMO, and he couldn't help but be a little curious and a little apprehensive.

The test papers for the CMO preliminary round were sent down, and Lan Jie took a quick look.

There are no multiple-choice questions in this exam paper, only fill-in-the-blank questions and answer questions, a total of 15 questions, 150 marks.

When doing math papers, you are not afraid of many topics, but you are afraid of fewer topics.

Fifteen questions are neither more nor less, operation.

Lan Jie operated, and he found that his father's bet accuracy was very low.

To be exact, Mr. Lan's accuracy is 0%.

The number of palindromes is indeed quite interesting, but the teachers who ask questions don't come up with this type of question at all.

The red and blue balls, which were loved by the math teachers in Sheep Middle School, were also missing.

Obviously, the CMO's teacher is a different system of people, and this group of people has a different way of thinking.

The most difficult part of this paper is not the last question, but the penultimate answer question.

There is a 300×300 white grid table, just ask: how many squares can be blackened at least, so that any three black squares do not form an L-shape, but as long as any white grid is dyed black, there will be an L-shape composed of three black squares. (13 minutes)

'This ...... It's a hard staining problem!'

When Lan Jie took a quick look at the test paper, he felt that the question of this staining problem was difficult to solve.

Calm down and ponder, it's really difficult!

The dyeing problem is a bit of a permutation and probability, but it is different from permutations and probability.

In mathematics, the dyeing problem is singled out in a school of its own.

Dealing with dyeing problems does not necessarily require the respondent to have advanced mathematical knowledge, it tests the ability of the respondent, including the ability to analyze the problem, solve the problem, and be flexible.

Because of the special properties of staining problems, staining problems are commonly found on IQ tests.

Lan Jinhui believes that the problem of dyeing is pediatric, and he never explains the problem of dyeing to Lan Jie.

Han Daxian does not think that staining problems are pediatric, but he rarely explains staining problems.

After all, dyeing is ultimately a question of IQ.

Students with high IQ can solve the dyeing problem without being taught by a teacher.

Students with average IQ can't be taught.

'I'...... I'm stuck!'

Rangier was sweating, he didn't care how many points he could get for the other fourteen questions, he only cared about this staining problem.

It doesn't matter if you win the CMO award or not, the most important thing is that IQ can't be insulted!

'What I'm most proud of is my IQ!'

'I have to get all 13 points!'

"Second math sister, hurry up and tell me how to do this problem!"

'Second sister?'"

'What about people?'

'Play disappear at the moment of moment!'

'Oh, woman. ’
