Reborn in 2000 as a scholar

There are three teaching buildings in Qingfeng High School, except for the Shuren Building at the end of the school, which is used by cram schools; the first teaching building with a height of 6 floors is used for senior one to senior three.The original No. [-] teaching building is not only used for art specialty courses for art specialty students, but also for Olympiad classes.However, Lin Jinqi knew that after he graduated this year, due to the continuous expansion of the school's enrollment, the second teaching building with only two floors would be demolished and rebuilt into a teaching building with the same scale as the first teaching building.

Today is the first day of the Mathematics Olympiad class, Lin Jinqi and other newcomers came here with trepidation.And Lin Jinqi didn't expect that the Xueba system started the "milestone task" at this time, and the first requirement of the two milestone tasks of the Olympiad class is "becoming a regular team member", and the reward is "black technology game development engine" " and the right to use the two software "Black Technology Animation Production Factory".The system said that in order to motivate Lin Jinqi to make progress, it had done its best and said that it showed a kind smile like an old father at this time.

Lin Jinqi just chuckled and thought to himself what the hell is that "old father's kind smile"!Lin Jinqi looked at the 15 new players who were shortlisted, 10 of them were in the first year of high school, and only 5 were in the second and third year of high school.Lin Jinqi heard that this is the rule of the Olympiad class. The standard of senior one will be much lower than that of senior two and senior three. After all, senior one students have at least two years of training time, and the probability of being able to develop into talents is higher.As for the students selected in the third year of high school, the teachers generally have a stocking attitude.After all, even if they are trained, they can only participate in the national finals at most.By the time of the world finals, they had already graduated from high school, thus losing their qualifications to participate in the finals.

"Hey, this year's rookies are here? Think we were so young back then?" Just as Lin Jinqi was looking at the classroom, an abrupt voice sounded behind him.A short-haired boy in school uniform said with a naughty smile on his lips, "Remember to buy us a drink after the first remedial class is over! This is the rule. After serving us, maybe I will teach you a trick or two to solve the problem Method. Don’t talk about participating in math competitions in the future, at least ensure that you will benefit from it in the college entrance examination.”

Hearing the boy's crazy words, the girls all showed timid expressions, while the boys were either disdainful or angry, but Lin Jinqi had a calm face, as if nothing had happened.He knew too well the Olympiad classes of Qingfeng High School in the past few years, not to mention participating in the national finals, even the city preliminary rounds were beaten by Taoxi No. 7 Middle School, Donghe No. [-] Middle School, Lishan No. [-] Middle School and Shuangxing No. [-] Middle School. The number of finalists for the provincial semi-finals was even comparable to that of Double Star No. [-] Middle School, ranking No.[-] in the city's high schools, which can be said to be the lowest stage since Qingfeng High School participated in the Olympiad.If this boy is really as good as he said, the Qingfeng High School Math Olympiad class would not be defeated again and again, and would almost lose face in front of several other high schools in the same city.

The silence in the classroom was not broken until Liu Guoqing, the head of the coaching team of the Math Olympiad class, came in. He walked to the podium and said directly: "There is no special discipline in our Math Olympiad class. If you are late for more than 15 minutes, you will be considered absent; if you miss three times, you will be cleared immediately." Retire. Unless discussion is allowed, speaking in class will be regarded as a violation of discipline. One violation of discipline will deduct 10 points from the next in-class test score; Violation of discipline three times, dismissed."

After finishing these few items, Liu Guoqing looked at everyone, "The reason why you are so strict is that I hope you know that the school wants you to increase the honor, and you want to win the college entrance examination points for yourself. Anyone with a bad attitude will be punished by me." No need here. The last one, since all mathematics competitions limit the number of participants in each school, the school registration will give priority to the six selected players; Selection. As for how to become a regular player, we have a monthly selection test for the regular team members, and the top six are the regular team members. Please note that we have at least one in-class test and a regular selection test every month. If you feel that you cannot bear the pressure of such an exam, you can quit now."

Liu Guoqing waited for a few minutes, and seeing that no one asked to quit, he ordered, "Everyone find a seat and sit down. We don't have teaching materials for tutoring, but you need to bring enough pens, notebooks and draft paper. I checked, and the freshmen A few more appear to have arrived empty-handed. Now you have 10 minutes to return to your classrooms to bring what you need; more than 10 minutes and I'll be late."

As soon as Liu Guoqing finished speaking, several people in Lin Jinqi immediately ran out of the classroom to get things.Fortunately, Lin Jinqi and Liu Xing both brought their own stationery, so they found an adjacent seat and sat down.The classroom is very quiet and the atmosphere is very tense.

In less than 10 minutes, the students who had just left to pick up stationery came back panting.Seeing that everyone was already seated, Liu Guoqing wrote a question directly on the blackboard, and then said: "Give everyone 15 minutes to think about it, and then I will take a look at your problem-solving ideas. Of course, if you can finish it within 15 minutes Those who solve the problem can also signal me in advance. Don’t be shy, and don’t worry about making mistakes, we are just studying the problem, this is not an exam. Alright, the timer starts.”

Perhaps it is because new players are entering the class today, so this question is not very difficult.At least for Lin Jinqi, it took about 5 minutes to think about a solution.But Lin Jinqi didn't raise his hand to signal, because he felt that this idea was a bit too complicated.The beauty of mathematics is that she can use the simplest and most direct method to find the answer. That kind of complicated and cumbersome problem-solving thinking is simply tarnishing the beauty of the goddess of mathematics.So Lin Jinqi thought for a while, and finally found another way of solving the problem that he thought was easier.

At this moment, someone raised his hand.Teacher Liu didn't seem surprised that the boy would raise his hand, so he handed him the chalk, "Yu Yahuang, come and write down your idea of ​​solving the problem, and let's see how it goes."

This boy named Yu Yahuang was a sophomore in high school. He was thin and tall, with a pale complexion, and he felt weak when the school uniform was hanging on him.He adjusted his glasses, and then wrote his problem-solving process on the blackboard.Lin Jinqi looked at it, and it was the first plan he thought of.Yu Yahuang took some time to write the problem-solving process on the blackboard. Teacher Liu glanced at it for a while, nodded and said, "It's not bad. It's not bad to be able to solve the problem in such a short time. According to your strength, Orsay It is no problem to enter the first prize in the provincial semi-finals. But you have to know that only the special prize is eligible to participate in the national finals, keep working hard!"

After encouraging Yu Yahuang, Teacher Liu looked at the other students, "What about the rest of you? I won't force you, but you have to understand that if you don't solve this problem within 15 minutes, you will basically skip the rematch." This is your end."

"Ms. Liu, I heard that there is a freshman with a perfect score in the mathematics selection test of the Olympiad class. Why don't you ask him to talk about his problem-solving ideas." What's the difference between full marks and us."

"Yang Wenzhuo, why don't you come up and talk about your problem-solving ideas?" Liu Guoqing looked at the student coldly, "I warn you, don't think that you are a little clever and do whatever you want in the class. No one who can come to this class Stupid, if you mess up again, even if you ask your father to intercede again, I will kick you out!"

Under Teacher Liu's warning, although Yang Wenzhuo was not convinced, he didn't say anything more.But Teacher Liu looked at Lin Jinqi, "Lin Jinqi, is there any difference between your problem-solving ideas and Yu Yahuang's? If so, please come up and write about your problem-solving ideas, and let's compare and see if there are any advantages."

Lin Jinqi also went to the blackboard, took the chalk from Teacher Liu, and wrote his own problem-solving steps next to Yu Yahuang's.Lin Jinqi's problem-solving steps were obviously much more refined than Yu Yahuang's, but not all the students present understood it, and even Liu Guoqing himself was a little surprised.

After reading it, he said: "It's a wonderful problem-solving process! But I'm curious how you came up with this problem-solving idea? The process is not important, the idea is the key. For many math problems, as long as you think of , it is only a matter of time before it is solved. If the thinking is wrong, it is easy to do a lot of useless work.”

"I also thought of the previous set of problem-solving ideas, but I think this set of methods is too cumbersome." Lin Jinqi did not hide that he knew Yu Yahuang's problem-solving methods for a long time. He mentioned several problems he used in solving problems. formulas and theories.Although most of them come from high school knowledge points, there are still a few knowledge points from college mathematics.In particular, one of the key formulas is only learned at the university level. Without the help of this formula, it is difficult to deduce this problem-solving process.

"Isn't it just to use college mathematics to cheat! What kind of problem-solving method is this?" Yang Wenzhuo said mockingly.

"Yang Wenzhuo, I think you don't plan to stay in the Olympiad class anymore? Go out if you don't want to study!" Liu Guoqing pointed to the back door, "Don't disturb other students. If you don't want to study, just tell me, I will Immediately disqualify you."

After saying this, Liu Guoqing looked at Lin Jinqi and said, "Strictly speaking, the Mathematical Olympiad does not prohibit the use of knowledge points that have been exposed to at the university or higher education level. However, since this competition is for high school students, Therefore, both the proposition group and the marking group still recommend using high school knowledge points to answer. But this is not all university knowledge points. If middle school students who are interested in mathematics also have the opportunity and ability to get in touch with and learn. Okay, everyone Let’s look at Lin Jinqi’s problem-solving ideas, and compare Yu Yahuang’s problem-solving ideas, and experience their different views on the same problem.”

The training of the mathematics olympiad class is basically based on problem solving, and then interspersed with the teachers' combing and connection of knowledge points, and then explaining how to think about the answer ideas of some key points.This kind of heuristic education is tantamount to listening to the heavenly scriptures for ordinary middle school students, but for the Olympians who are qualified to sit here, this kind of education method opens up the shackles of their imagination.

After the Olympiad class training, Yang Wenzhuo blocked Lin Jinqi and threatened: "Let me tell you, don't think that you are a top student. In my eyes, you are not as good as a piece of shit. Believe it or not, I made you I can't stay in this school!"

Lin Jinqi didn't intend to show his sharpness at first, but he is not the kind of person who will hide when others come to him.Seeing that there was no one around, he directly grabbed Yang Wenzhuo's collar, lifted him up and said, "Try it! Isn't it because of having a good father? No one is afraid of anyone!"
