The Protagonist’s Halo

Before the semi-finals, Mr. Wu took a few students who entered the semi-finals and soaked in the laboratory for several days.

When Cheng Yin was doing the experiment the first day, Mr. Wu and another teacher from the laboratory watched the whole process.

"You are too good as a student, even the average teacher can't match her level."

Teacher Wu nodded approvingly, but after the teacher left, he pulled Cheng Yin and said, "You did a good job. As long as your mentality does not collapse in the rematch, the experiment is stable, and I have nothing to guide you. , I asked the lab teacher for a key. Whenever you have time to do the experiment, you can come by yourself, and he will recognize you. But after you leave the lab, if you see Xu Junmeng and the others, if you ask about your experiment How about it, you just say it's okay."

He sighed, "The rematch is coming soon, so you still don't want to beat their test mentality."

Xiao Han: "..." Is it so serious? Are current students mentally fragile?

Well, Teacher Wu has spoken so sincerely, Xiao Han nodded anyway.

After the experimental course, the sound is separated from the others.

When I ran into Meng Mi by chance, the primary school girl asked silly Baitian, "Senior sister, why didn't you do the experiment with us? It's good for everyone to discuss with each other occasionally."

Remembering what Mr. Wu said, Xiao Han said sincerely, "I prefer to do experiments quietly by myself."

Meng Mi really believed it too, "So that's how it is."

…

The semi-finals are coming as scheduled. The theoretical part of the semi-finals will be unified by the National Competition Committee, with a full score of 160. The top 60 students in the theoretical examination will enter the experimental examination.

After sending the students into the examination room, the teachers all came to the lounge.

The leading teacher of another middle school said, "Your student named Cheng Yin won't be handing in papers in advance this time."

It is also a full score. Because Cheng Yin finished writing and handing in the paper less than half the time in advance, he was able to reproduce all the questions and answers after he came out. It can be said that he has gained a lot of fame.

The teacher was a bit resentful. He had three students in the same examination room as Cheng Yin. They learned that Cheng Yin had handed in the papers in less than an hour, which caused their mentality to take the exams and their scores were unsightly. They can only fight again next year.

Teacher Wu smiled and said, "It depends on how she is doing. I think Cheng Yin, a student, is still very calm and proper, and won't do anything uncertain."

What's wrong with handing in papers in advance? It's still full marks.

I don't know if it's because of the student Cheng Yin, that Teacher Wu also felt that he was floating a little bit.

"It seems that you have high hopes for your student, so I wish you a good grade in advance." The teacher who was stunned was broken in his heart, and I don't believe it. This time the theory plus experiment, Cheng The sound can also get full marks.

Most of the unqualified students were screened out in the preliminaries, and those who can make it to the semi-finals, which one is not the best student in the middle school, the province’s elite students in physics, it can be said that the worst student is also a student. I heard that the quality of the students in this competition is quite good, and there are several talented people in other cities. It is not easy to stand out among them. I think that this teacher has no intention of resenting Cheng Yin, and I start to nervously. I squeezed a sweat for my students.

In comparison, the students in the examination room didn't have the time to be nervous at all, and were stunned by the questions on the test paper as soon as they came up.

You told me that this is the difficulty of the physics contest semi-finals? Are you bullying me?

Nearly one-third of the people in an examination room have experience in competitions, high schools and even junior high schools have participated in sports competitions, but looking at the overbearing large-scale finale of this rematch test paper standard, they feel the simple difficulty of the finals.

More examinees get the papers and try to calm down and do the questions, but as the amount of calculation for each question becomes larger and larger, the difficulty of thinking becomes more and more difficult, and there is a feeling of being played by the teacher. .

The first question is a hot topic. The thinking is not difficult but the calculation is relatively large. There is also a small amount of approximation. If the strength is not enough, the students will be prone to fatigue in the middle and late stages of the calculation, which can be said to be a distraction.

Starting from the second question, the difficulty of thinking of three consecutive questions has subverted common sense, and people can't help but take a breath.

The fifth question and the sixth question test sensors and optoelectronic models. They are relatively novel, but they all test the ability to build models and the physical level.

Xiao Han thought about it, modeling ability is very important, after all, a large number of physics competition problems have modeling. It is that ordinary high school students have no access to this level at all.

The seventh and eighth questions are about the expansion of the vector field. The movement of the particles under the action of the Lorentz force and the linear restoring force made Xiao Han feel very familiar, because it was mentioned in the competition training, and was evaluated as'so difficult to speak. What's the use?','I can't take the test anyway,''has always been used to pretend to be a showman'.

Probably because there are too many people talking about it, the person who asked the question simply showed it off. Didn’t you say that you can’t take the test? Then I will test you.

Although Xiao Han didn't feel nervous at all after reading the whole paper, he still felt the malice from the person who wrote the question.

After reviewing the subject, Xiao Han began to write, relying on the memory of the palace, Xiao Han did the first question very easily.

Although the calculation amount of the second one is not as good as the former, it combines the reflection coefficient, the background radiation of Weibo and the heat conduction investigation, and it just plays a big trick, making even students who are very familiar with these three important knowledge points easy to make mistakes. Because it also involves some calculus.

The third question and the fourth question are similar, with surprising brains and challenging cognition.

The other students almost cried in their hearts.

Twenty minutes have passed quietly, and for Xiao Han, who had done a complete paper in less than an hour in the preliminaries before, also slowed down.

The fifth and sixth questions require high modeling skills. They need keen insight and the ability to analyze photos in combination with conditions. Xiao Han, who has a memory palace, is not embarrassed by this at all. Keeping a sober and calm state, expand Brainstorming.

The pen did not stop, and wrote a piece of answer speculation on the draft paper.

Seeing that not long before the exam started, there was an invigilator who came down and walked around.

I accidentally took a look at the exam questions and took a deep breath. Is this year's physics semi-finals of this level?

The examination room was difficult to speak, and was afraid of disturbing the candidates' thinking. The two invigilators exchanged their eyes and understood in an instant. This year's rematch test questions are extremely difficult, and they are about to reach the final level. Then the two teachers showed sympathy to the candidates who were in deep contemplation.

Xiao Han seems to stand out from the crowd, because among the candidates who are struggling with super-difficult physics problems and whose mentality is on the line of collapse, she looks like the kind of problem-solving is very relaxed and happy, and there is no'work hard' at all. The look, only fun.

Where is the genius seedling.

…

In the rest room, half of the exam time has passed, but within an hour and a half, none of the candidates turned in their papers in advance. This is different from the preliminaries. The students who can’t do it simply hand in the papers and leave. Everyone who can go to the semifinals It is not easy for students to compete. They put a lot of effort and sweat behind their backs, so no matter how difficult the problem is, they will sit until the last minute.

Teacher Wu was also a little nervous. Cheng Yin's experiment part was done at such a high level. It would be a shame if he couldn't enter the experiment exam because of his insufficient grades in the theory part. Although there is still a chance to continue to participate in material competition in the senior year, there are too many variables after all.

Teacher Wu said that Cheng Yin was the latest candidate in the competition he had taken this year and the shortest training time, but he was the most promising candidate.

Other teachers talked about the test questions of this physics semi-final, "I don't know what level of difficulty the test questions are?"

"So far, the Association of Materials Industry hasn't said anything about it. It should be about the same as in previous years."

Two hours have passed since the exam, and students finally came out of the exam room. Teacher Wu saw Cheng Yin through the window. His eyes widened. He was relieved not knowing why he saw Cheng Yin hand in the paper in advance. He secretly told himself that he must not show it, otherwise Cheng Yin might have the idea of ​​handing in papers in advance, which would be too stressful for the students.

Teacher Wu had told Xiao Han where to find him after leaving the examination room, so Xiao Han quickly found the lounge.

As soon as Mr. Wu saw her, she hurried to meet her, "Don't be nervous, how difficult is the test?"

Xiao Han thought for a while and said, "Fortunately, it's harder than the preliminaries." It was a bit difficult for her to evaluate the difficulty, so she had to compare the preliminaries.

A teacher next to him listened to the corners of his mouth, and the answer was no one. The difficulty of the rematch is higher than that of the preliminaries. That's for sure, should I talk about it?

This is a physics competition where genius learners gather. There will naturally be a second and third one after the paper is handed in early. All the other teachers are full of confidence except for Mr. Wu, who is just talking to Cheng Yin, etc. With his own students returning triumphantly.

After ten minutes, no candidates came out.

…

Twenty minutes later, no candidates came out.

…

Thirty minutes later, only one candidate came out, Cheng Yin, and the teachers in the lounge started to stare at them. The test time was 180 minutes, and now there are only 30 minutes left, except for Donghua High School. Of Cheng Yin, there is no second person to hand in papers in advance.

Is the topic of this semi-final so difficult?

They couldn't help looking at a pair of teachers and students sitting at the corner sofa table. This time Teacher Wu worried that Cheng Yin was tired from the exam, and did not let her write the questions and answers. He only exchanged privately about the exam questions, and then frowned. It's getting tighter, and it's about to become a ravine.

"Are you sure it's an exam question of this level." Just listening to Cheng Yin said, Teacher Wu felt that it was too much beyond the level of the semi-finals.

Xiao Han nodded, took a piece of white paper next to it, and wrote out the few questions she found the most difficult. In order to save time, she didn't have time to write the answer, so she was snatched by Teacher Wu.

At this time, other teachers who were already a little nervous and anxious also surrounded Mr. Wu. A young male teacher who saw the process tone change during the last preliminaries was shocked when he saw the first question, "I'll go ."

The other teachers are also dumbfounded. This difficulty is obviously beyond the previous ones.
