God of black technology

Examination is an eternal topic for students.Countless students fell into the pit of the exam one after another.

And for these students, this national competition is even more—a huge pitfall.Don't look at this teacher who doesn't seem to be aggressive, and has a cheerful look on his face.But if he really dared to do something, I'm afraid the first one who couldn't spare the student would be this kind-faced teacher.

Unzipping the sealed bag, he took the roll out of the sealed bag.Then put it on the podium, looked at the students in the audience and said, "Okay, now hand in all your books about mathematics, and hand in your draft paper. Everyone is the elite of each provincial team, and I don't want to see you here If you have any cheating, I don't think everyone wants this to happen, right?"

After speaking, the students in the entire examination room consciously handed in their own.The invigilator said with a smile, "After handing in the materials, everyone can just sit in their seats."

Back in their seats, all the students are waiting for the teacher to distribute the test papers.Then another invigilator walked in and said with a smile, "Everyone, try to relax when you do the paper later, and don't think too hard about the paper. You are all elites in the province and city. I believe this paper is not difficult." It's yours." After finishing speaking, he and the invigilator who had stood on the podium earlier handed out test papers and draft papers.

"If you have any unclear questions on the test paper, just raise your hand and ask, don't whisper, the draft paper is not enough to raise your hand. After an hour, if you think you can hand in the paper, just raise your hand."

While handing out papers, he was talking.After a while, everyone got papers and draft paper.Wang Yun glanced through the paper quickly, and found that there seemed to be no mistakes or omissions in the paper.He will rest assured to examine the question——

The first question is very simple, and Wang Yun will do it quickly!

The second question was not difficult, so Wang Yun finished it easily.

He thought that the first two questions were probably just an appetizer, so that candidates could familiarize themselves with the content of the national competition.These two questions are even simpler than the first two questions in the Yucheng final paper.

The third question, the fourth question emmmmm...why does Wang Yun always have the idea that these questions are a little too simple.Although the topic is a bit convoluted, for those who really understand mathematics, this is really - it can't be easier!

Starting from the fifth question, the difficulty increased a little.But it was just a few. Wang Yun quickly finished the fifth question and started to work on the sixth question.It turned out that the national competition was not as difficult as he had imagined. Wang Yun was doing it wholeheartedly. Even so, Wang Yun's speed in solving the questions was not slow, and it could even be said to be very fast.

After completing the first five questions, Wang Yun felt that it was necessary to re-examine the test papers for the preliminary national competition.There are six more questions in the back, that is, after the tenth question, there is an additional question.Wang Yun just glanced at it roughly, and started to work on the previous questions, without having time to examine the latter questions at all.

Now that I think about it, the following questions should not be too difficult.

Thinking about it, Wang Yun began to look at the sixth question.To his surprise, the difficulty of the sixth question was raised a level higher than that of the fifth question.It seems that the teacher who produced the paper wanted to make a fuss about the passing line.

Is it possible that the qualification to enter the semi-finals this time is the passing line?The passing line is a watershed. If you can enter the passing line, I am afraid that you will be able to get the second grade.But if you can't enter the passing line, then——it will appear particularly embarrassing.

National three consolation prize, good to go!

After completing the sixth question, Wang Yun continued to do the questions.In the whole classroom, some people were scratching their heads, some people were thinking hard.He is probably the only one who can achieve Wang Yun's smoothness.

The seventh question seems to be another hurdle, and the difficulty has increased a lot.But for Wang Yun, it was still a bit simple.Using calculus, the seventh question was directly solved.

The invigilator stands on the podium and can easily see the expressions of the students.

And what caught his attention was undoubtedly the pretty-looking high school boy sitting in the front row.From the beginning to the end, there was almost no strange expression on his face.Without even thinking about it, I just took the paper and started doing the questions.If it weren't for the fact that the questions of the national competition were kept strictly confidential, the invigilator would have suspected that Wang Yun had read the test papers before and even got the answers.

He walked to another invigilator and said, "Look at that examinee, he seems to have been working on the questions from the beginning without stopping."

Another invigilator glanced at Wang Yun, and then said, "He is the champion of the Yucheng competition, and the level of the Yucheng competition is still there. He just lost a little last year. His ability to do this proves that Yucheng is not something to mess with this time." character of."

"That's right. I see that the other students seem to have a bit of a bitter face, and he is the only one who has been writing the answers blankly. If it weren't for this set of papers, which is our first time today, I guess I would think that this guy It has something to do with the person who produced the paper, I have already read the answer."

"Those who can participate in the national competition have more or less talent. This guy is the champion of Yucheng City, that is to say, he is the strongest one in Yucheng City. I think he can do it so fast. I am not surprised at all. Yucheng used to be a major province in the competition, and its loss last year was a bad news for Yucheng. With a comeback this year, I don’t think Yucheng will easily let go of the championship position.”

"Not necessarily, right? Erhu Province is a province that produces champions almost every year. In addition, Suzhou Province and Shanghai City are very strong this year. I think Yucheng, Xuan!"

"But no matter what, it's really good to feel that there are so many talents." The invigilator said lightly, "Especially most of the candidates will join our Beijing University."

After the two invigilators looked at each other and smiled, they didn't continue talking.

After finishing the seventh question, Wang Yun has already started working on the eighth question.In the examination room at this time, the fastest candidates, except for Wang Yun, were still thinking about how to do the sixth question.

The students below could be seen clearly from the podium, so naturally the invigilator had no intention of going on.

The original place of the exam was the preparatory class of Peking University, not the lecture hall.In addition, the invigilator still has some basic trust in this group of students. After all, these students are elites.Cheating on this kind of exam is not worth it for them, and they will be ridiculed, why bother!

After finishing the eighth question, Wang Yun directly started to do the ninth question.

This is an algebra problem, and the question is a bit convoluted, but it's okay for Wang Yun.After reviewing the questions, he kept gesticulating on the draft paper and wrote...

After all, the invigilator could not resist his curiosity, stepped off the podium, and stood beside Wang Yun.Looking at Wang Yun's test paper, he kept nodding his head——

Let's not talk about other things first, let's just say that the surface of this paper is clean and tidy. Although the writing is not very beautiful, it is enough.When correcting the test paper, any teacher will not grade it after seeing such a hand-pleasing test paper, and must read it carefully several times.If the correcting teacher can be patient and read it a few more times, maybe there will be some points that should not be deducted and will not be deducted.

With his hands folded in front of his chest, the invigilator looked at the steps of Wang Yun's answer.

perfect!Very good, both the steps of the solution and the answer are correct.

It seems that the champion of Yucheng still has a few brushes, not embroidered pillows.After finishing the ninth question, Wang Yun didn't realize that there was another person beside him, and he had even stood there for a long time.He started to look at the tenth question, which might be too difficult for other candidates, or even a bit beyond the outline.

This is a number theory problem, the invigilator thought in his heart, I don't believe you can even do number theory.

After Wang Yun looked at the topic again, he raised his eyebrows.Slowly calculating on the draft paper, the invigilator frowned, pursed his lips and did not speak.

His draft paper was a little messy, probably only he could understand it.The invigilator looked at it for a long time and didn't understand it. When Wang Yun put all the formulas on the draft paper on the answer sheet, the invigilator was stunned.

Fog Grass!Are the current high school students going against the sky?Complex variable integral method, this guy solves this problem with complex variable integral method of number theory?Is this still a high school student?

After writing this question, Wang Yun shook his hands and continued with the last question, which is the additional question.

This additional question is not number theory, but calculus, and Wang Yun's eyes light up slightly.This problem should be solved using Laplace's theorem.

After finishing the draft, Wang Yun directly wrote down all the steps on the answer sheet.

"???" The proctor's face was full of question marks. This level, not to mention the graduate students of Peking University, can almost beat most of the undergraduates of the School of Mathematics at Peking University, right?

You tell me this guy is a high school student?I really believed in your evil!

Laplace's theorem is a partial differential equation, but its application in calculus is not necessarily as much as in physics.If you calculate according to the usual differential, you probably won't be able to solve this problem so easily.Let me go, this student... is really scary.

The invigilator walked back to the podium, another invigilator nodded at him, and said with a smile, "How's the result of watching the battle?"

"Mom, this is not a high school student, it's like beating an undergraduate student." The invigilator himself is not very old, and he said slightly, "The last question, he solved it with Laplace's theorem. Damn it , this guy must know a lot about fluid mechanics."

"..." What kind of feeling does it feel to have a person who is good at physics out of nowhere in a good math competition?

As we all know, people who are good at mathematics are not necessarily good at physics, but if you change careers to study physics, there is a high probability that you can succeed in your studies.But people who are good at physics will not necessarily change their careers to study mathematics.

"Teacher, can you hand in the test?" Wang Yun raised his hand, and the invigilator nodded expressionlessly, "After checking your name, city, school and test number, you can leave the test room."

Wang Yun turned his head and looked at the required information on the test paper again. After finding that there were no mistakes, he packed his things and walked out of the examination room.

Mom, what kind of god is this, you left the examination room in an hour?Many candidates who were still scratching their heads watched Wang Yun leave the examination room with dull eyes.The invigilator coughed lightly and said, "Everyone, stop paying attention to others. The exam is over in one hour. If you have time to care about others, why don't you finish the paper yourself first."

The invigilator's words really reminded many candidates.

They were all caught up in, what the hell, this guy is such a cowhide, he's really a god, and he couldn't extricate himself from the emotion of leaving the exam room so quickly.If it wasn't for what the invigilator said, they probably wouldn't know how long they would have been in a daze.

Thinking of this, the group of students began to look bitterly at the paper on the table.

Why can other people do it so fast, but they find this paper so difficult?Is the gap between people really that big?

Especially the student sitting behind Wang Yun, he has mixed feelings now.Mom also, the god-man in front, the handwriting on the answer sheet is neat, and all the questions have been written.And he kept looking at the divine man in front of him, without even stopping to think, and kept writing formulas and steps on the paper.

"..." Why did he meet such a god-man, why did this god-man hang and beat high school students?Wouldn't it be better if you go directly to Beijing University?Why do you still come to hang and beat mortals, will it make you happy? ,

Walking out of the examination room, Teacher Lin was still waiting outside.Seeing Wang Yun walk out of the examination room for the first time, he asked with a smile, "Isn't that a big problem?"

Wang Yun nodded slightly, "There should be no problem. For me, these questions are not too difficult."

"What is the additional question?"

"The application of calculus is actually quite simple. You only need to be familiar with calculus, and it is not too difficult to solve it."

Teacher Lin patted Wang Yun on the shoulder, and said with a smile, "Looking at your appearance, I know you should be fine."

After a while, Yuan Chengde walked out of the examination room.

"How is it?" Teacher Lin then asked Yuan Chengde about his experience in the exam. Yuan Chengde smiled and said, "The test papers for the preliminary round are not too difficult. I guess there will be a highlight in the rematch."

"Looking at you, this year is almost stable." Teacher Lin smiled happily, "At least it's not like last year, when everyone was wiped out and only got the third grade."

"Mr. Lin, so you are worried about this matter." Wang Yun said dumbfoundedly, "There shouldn't be any problem."

"Well, not to mention the third grade, I am very confident that I can get the first grade." Yuan Chengde patted his chest and said as if to assure, "Mr. Lin, don't worry, we will not let you down. .”

Teacher Lin said with a smile, "Be careful yourself, don't capsize in the gutter. Tonight, the guild will enter the semi-final score line, and the results will be released around nine o'clock. After logging in to the official website of the competition and entering your test number, will you be able to see the results?" Everyone's grades. The grades are the same as our Yucheng's grade distribution rules, from top to bottom, all the way to the lowest score."

"Look at the gap between yourself and other provinces and cities." Teacher Lin wanted to teach Yuan Chengde a lesson early in the morning. Self-confidence is a good thing.But excessive self-confidence is not necessarily a good thing, so Teacher Lin wants to beat Yuan Chengde.In fact, Wang Yun has always given Mr. Lin the feeling that this student has no sense of his own position, while Yuan Chengde is sometimes overconfident.

The third person to come out was Luo Zhendong. He glanced at Wang Yun and walked towards the teacher who led the team in Shanghai.

Teacher Lin was stunned for a moment, thinking that when the student came out just now, he gave Wang Yun a very strange look.It can even be said that he was a little astonished. He looked at Wang Yun and said, "Do you know that student?"

"Teacher, you are talking about Luo Zhendong." Wang Yun thought for a while and said, "He is the champion of Shanghai, but his mind is not so clear."

Yuan Chengde nodded in cooperation, it is true that Luo Zhendong's mind seems to be very unclear.

Teacher Lin didn't care about this matter. After a while, candidates walked out of the examination room one after another.The front is still full of confidence, the more the back comes out, the more dejected.When Rong Lei came out, it was almost time to hand in the paper.Wang Yun patted Rong Lei's shoulder, but did not speak.Silently comforting Rong Lei, Rong Lei took a breath and said, "I'm going, the national test paper is too difficult. I don't know whether the calculations are correct or wrong for so many questions. I always feel that I Probably only able to get the National Three."

"It's not that serious." Yuan Chengde comforted, "There are still many people who can't even finish the test. If you can finish it, you are already very good."

At this time, no one was thinking about the answer.Who knows the answer, isn't this looking for death?Before everyone came out just now, Wang Yun and Yuan Chengde had checked the answers, that is, there were some differences in the additional questions, and the other questions could be matched.

"It's terrible, it's terrible!" Wang Qiuyang said, covering his face, "I failed the exam this time, so I probably won't be able to enter the semi-finals."

"I'm going, Wang Shen, don't scare me, you won't be able to enter the semi-finals, then I--" Liu Yang said dumbfoundedly, "Without this, the national competition this time is even more difficult than last year, It’s too difficult, it’s too difficult for me. Why are you so unlucky, this year’s competition paper in Yucheng is much more difficult than in previous years, and the national competition paper is also difficult but not weak, alas, I feel that I am too unlucky.”

"Stop talking, I just want to be quiet now." The time for handing in the papers has come, and all the students walked out of the examination room.After Mr. Lin gathered all the team members, he explained to Wang Yun and Yuan Chengde what he had just explained.

Many students returned to their dormitories with complicated expressions, as if they were waiting for the verdict of fate.

Wang Qiuyang was inactive all day, lying in the dormitory like a salted fish, not speaking.Even when eating, he, who is usually the most active, lay on the bed and stared at the floor, which gave Wang Yun a big jump.

"I said, Wang Qiuyang, do you really not eat?"

Wang Qiuyang shook his head and said, "Why do you want to eat?"
