Although the drama of "warm rice solves problems" is old-fashioned and vulgar, it still brings a huge sense of accomplishment and satisfaction to Jiang Shuiyuan. ◢ With * dream * small ◢.1a

Hurriedly solving lunch, not taking a break in the morning, he picked up his pen again and began to solve the fourth question. The fourth question is that I have already thought about my thoughts before eating, and I have made a start, so it is smooth to get started.

By three o'clock in the afternoon, Jiang Shuiyuan had finished solving the fifth question, leaving only the last question with some vague thoughts. He took the time to look left and right, only to see Zhang Jin's brows tightly locked, as if he wanted to kill the question in front of him with angry eyes; Hu Peiwei also thought about the test paper, obviously encountering a roadblock.

Question 4 is difficult, right?

Thinking of this, Jiang Shuiyuan felt a little more proud: Don't look at you as the first place in the Huguang semi-finals, I am afraid that you will be helpless when you encounter a problem of this magnitude. Just like what is said in "Water Margin": You are like a ghost, and you also eat my mother - no, it's my footwater!

Encouraged by this, he felt that his mind was a little more flexible than usual, and he soon found the right way to solve the problem.

It seems that today is an auspicious day for my zodiac, and everything is fine! Leave Uncle Ge and Xiao Jinzi for dinner, you can eat by yourself, I am going back to the cafeteria of Jingshi University! Just when he was happy, Hu Peiwei suddenly stood up and said softly: "I'll go out for a walk." ”

Jiang Shuiyuan, Zhang Jin, and Uncle Ge were all stunned, except for Teacher Shen. He bowed his head slightly: "It's all done?"

"Hmm. ”

"Yes, let's go out and breathe!"

Although Jiang Shuiyuan didn't look up at Uncle Ge's face, he could guess that at this moment, he must be full of depression and hatred: as a top student of Jingshi University, he was a proud disciple who had been selected and cultivated with great difficulty, and he originally planned to avenge himself, but he was easily cut off in the first round.

Not to mention Uncle Ge, Jiang Shuiyuan felt even more hot on his face. One moment he was satisfied, but the next moment he was slapped in the face by someone else, and he was dumped for a whole question, which is no less than running 3,000 meters and being lapped. The key opponent is still a woman! Who can reason with? Now it seems that the drama of "warming up rice to solve problems" just now is like a clown show, which is just to make people laugh.

Jiang Shuiyuan bit his lip, tried to calm down, did not let his emotions affect his thinking, and solved the last question in more than 20 minutes, and then handed it to Uncle Ge without looking at it: "I will also go out for a walk." ”

Uncle Ge shook his head: "Twenty-three minutes, this is the gap!"

Jiang Shuiyuan knew what he meant, but he rarely didn't refute it, because he did see the gap between the two. With the bracelet bonus and inspiration, he was also dumped by Hu Peiwei. If there is no Uncle Ge to mention it on the side, the gap between the two will not be a matter of time, but whether it will be or not!

One day, one earth.

In other words, Hu Peiwei is like the position of Jiang Shuiyuan in Huai'an Mansion, every time you take the monthly exam, you don't need to deliberately review, and you don't need to play on the spot, you just need to push one question after another during the exam, God blocks and kills God, and Buddha blocks and kills Buddha. The topic is difficult, or not difficult, and the first grade is there, without increasing or decreasing. At this moment, Jiang Shuiyuan, like Li Zhili and Zeng Zhijun, is also a top student, but he has to go all out in every exam, and maybe a little luck, otherwise his ranking in the grade will fluctuate.

Teacher Shen was understanding: "You can't say that! The International Olympiad has six questions and nine hours, and it is still divided into two days, although our question may not be as good as them, but it is not much worse, and it can be completed within nine hours." Xiao Jiang completed six questions in six or seven hours, which is definitely a very good performance. As for 20 minutes more or 20 minutes less, what impact can it have? I haven't heard that the time for answering questions in the Olympiad is still counted in the score. ”

Uncle Ge shook his head again: "That's what I said, but there are thousands of changes in the examination room, and no one is sure if there is enough time." This question takes one minute less, and the next question has 60 seconds more time to think. One minute less to answer the question will give you 60 seconds more time to check the test paper. Maybe sometime it'll be converted into a score. Not to mention more than twenty minutes!"

Mr. Shen's attitude is still relaxed: "In my opinion, completing and getting the topic right within the specified time is victory, and as for how much time it takes, it is all a trivial. Since two of them have already completed the answers, let's cross-mark them?"

"Okay!" Uncle Ge agreed very simply.

Zhang Jin raised his head pitifully at this time, tears swirled in his eyes, so that he couldn't fall out: "I, I, I just made three, three, three questions!"

Teacher Shen smiled kindly: "No hurry, no hurry. Our exam is nine hours, and now only half of the time has passed, you still have plenty of time, take your time, don't rush!"

Uncle Ge glared at Jiang Shuiyuan: "Why are you still standing here stupidly? Hurry up and go out, don't affect Zhang Jin's answer!"

Please, can you be more explicit in your favoritism? Could it be that Zhang Jin is a pro, and I am the back? Jiang Shuiyuan pushed the door out while slandering. After going downstairs, he saw Hu Peiwei doing radio gymnastics in the courtyard, her graceful posture stretching freely in the slanting sun with the beat. This is what she said about going out to breathe? Sure enough, she is a student who combines work and rest, and both culture and sports!

Before Jiang Shuiyuan had time to shout "666", Hu Peiwei opened his mouth first to greet him: "You're done too?"

"yes, I'm done too. Jiang Shuiyuan bit the word "also" very hard, "I didn't expect it, I didn't expect that you are a beautiful girl who has fallen over the country and the city, and you are still a math bully! Admire, admire, you are really a cow of Gauss and Newton!"

"Do you want to do it together?" Hu Peiwei warmly invited. After being rejected by Jiang Shuiyuan in shame, she explained breathlessly: "Today's test papers, at least 4 questions are from our teacher Shen. I have been learning Olympiad mathematics with him since junior high school, and it has been five or six years now, and he already knows what routines and how to solve them, so it is very easy to get started. On the contrary, you, the first time you come into contact, do you have a feeling that a tiger eats the sky - I don't know where to eat?"

Jiang Shuiyuan stretched his waist and said honestly: "It's quite difficult! If it weren't for our teacher Ge scolding me a few words and letting me find a way to solve the problem, I guess I might not be able to finish it tonight." ”

Hu Peiwei said: "Those who can find inspiration casually are all god-level figures. That's like me, it's completely a routine based on the tactics of the sea of questions. ”

Jiang Shuiyuan immediately objected: "It's not right for you to say that! I remember that an academician Deng who was engaged in design once said, 'It doesn't matter if it's a white cat or a black cat, it's a good cat if you catch a mouse.'" In the same way, no matter who came up with the problem, no matter how you find the solution, as long as you can answer it correctly, you are a master. You think that Mr. Shen's questions are easy, and that is your hard work and accumulation in five or six years. At this point I lose to you, I am convinced. ”

Hu Peiwei smiled: "There are no others here, so let's not blow each other in business, it's embarrassing." But I would like to ask you a question. ”

"Don't dare to ask for advice, if you have any questions, you can ask, I promise to know everything and say everything. ”

"I've been wondering since I had lunch, why do you hear Lagrange suddenly have an outburst of inspiration?

Regarding this issue, not only Hu Peiwei was curious, but Teacher Shen was also suspicious.

He got the answer sheet of Jiang Shuiyuan, looked at the miserable handwriting on the paper, tried to resist the urge to deduct the surface of the paper first, and began to look for traces of Lagrange. The hard work paid off, and soon he saw the answer he wanted in the fourth problem: first construct a polynomial, then use the difference method and the Lagrange median value theorem to prove the difference, and then discuss the situation to get the result.

Hey, can you do that? Will it work?

After he finished reading it, he couldn't help but exclaim: "Amazing, amazing! Teacher Ge, you Xiao Jiang classmates are really amazing!"

"What's wrong?" Uncle Ge poked his head over.

"Look at how he did the fourth question," said Mr. Shen, handing the answer sheet to Ge Juntian's hand, "His solution is not only simple, but also very ingenious, far more wonderful than the answer I thought of before." If this question appears in the International Mathematics Olympiad, it will be a special prize based on Xiao Jiang's answer!"

The so-called special prize is an award awarded to an individual player in the International Mathematics Olympiad for a unique solution, which is usually different from the standard answer formulated in advance, and will appear more concise and beautiful. The special award does not consider the total score of the contestants, but only considers the excitement of the solution, which leads to a full score and a gold medal every time, but the special award is rare for eight times in ten years.

Because of this, the difficulty of winning a special prize is even more difficult than a perfect score, and the number of people who receive a special prize is even smaller.

After reading it, the corners of Uncle Ge's mouth curled slightly, obviously he was overjoyed in his heart, and he was still polite: "This guy is a little smart!"

Teacher Shen said generously: "You can't say that. Pei Wei is fast and takes less time, Xiao Jiang is new in thinking and stable in answering questions, and the two of them are really good at chess!"

Uncle Ge was stunned for a moment: Hmm, didn't you just say that if you can do it within nine hours, it will be counted as a grade, and there will be no impact if you can do it for 20 minutes or 20 minutes less?
