Twenty-six students of the math camp were taken to a small classroom by instructors, of whom 25 were boys and one was a girl.

"Hey, Shen Qi, look, there's a girl. Zhou Yu'an sat next to Shen Qi, as if he had discovered a new world.

"The girl who can enter the math camp must have something extraordinary. "Shen Qi has never seen a female teammate from the school competition team to the provincial team and then to the national team.

There was a blackboard hanging in front of the classroom, and in front of the blackboard stood two people, one fat and one thin.

The fat man is older, and the thin man is young. The older ones are the instructors, and the younger ones are the assistants.

"Ladies and gentlemen, please be quiet. The fat man said happily, more approachable: "My surname is Sun, my name is Sun Erxiong, a native of Northeast China, and I am the instructor of this Golden Autumn Mathematics Camp. Don't get me wrong, my Sun Erxiong and Sun Erniang have absolutely no kinship, I work in the School of Mathematical Sciences of Peking University, and I have never opened a black store. ”

Hehehe.

The students in the audience laughed and were amused by Sun Erxiong.

Sun Erxiong continued: "I was born in the countryside, my parents are not highly educated, and there is an old sister above, and I am the second in line, so I am called Sun Erxiong." The young man next to me is my assistant Qian Fang, and the two of us will spend 20 happy days with our classmates. Okay, now that I've introduced myself, I'm going to ask each of the 26 students to give a brief introduction to themselves. ”

Sun Erxiong has a list in his hand, which is a list of 26 students in the mathematics camp, and he named him: "Ding Hai, please introduce yourself first." ”

A small boy stood up: "Hello everyone, my name is Ding Hai, Ding is the Ding of the strong Ding, and the sea is the sea of the sea." I am from the First High School Affiliated to Central China Normal University, I especially like mathematics, and I have won the championship of the National Mathematics Elite Competition, so I am very happy to meet you, thank you. ”

"Okay, Ding Hai is very remarkable, he is the national mathematics champion, come, let us give Ding Hai the warmest applause. Sun Erxiong took the lead in applauding with a smile.

Bang bang bang.

The audience burst into symbolic applause, but it was not too enthusiastic.

Zhou Yu'an slapped his hands lightly twice, and complained in a low voice: "This guy from the First High School of Central China Normal University has no emotional intelligence, who can enter the mathematics camp of Peking University, who has not won the championship of mathematics competition? What is the second-level league of the Mathematics Elite Competition, isn't he begging for a slap in the face? Wait a while, Shen Qi, as soon as you speak, everyone, my name is Shen Qi, and I have won the IMO championship with a perfect score...... Hehe, sit back and wait for Shen Qi's boss to pretend to be forced. ”

Shen Qi didn't speak, he silently observed the environment of the classroom, as well as every student, fat instructor, and thin assistant.

Sun Erxiong glanced at the thin assistant, who operated a remote control, brushed and pulled, and a curtain slowly fell above the blackboard, and the projector hanging on the ceiling of the classroom was activated at the same time, projecting light to the curtain in front.

The thin assistant plugged a data cable into the laptop in front of him, only to see a clear line of text displayed on the screen: "If you zoom in on an apple the size of the earth, how big are the atoms in the apple?"

Sun Erxiong still asked with a smile: "Ding Hai, can you see the content projected on the screen?"

Ding Hai: "Yes." ”

Sun Erxiong: "Then may I ask, how big are the atoms in the apple? This has nothing to do with mathematics, it's just a comprehensive test of common sense, Ding Hai, just say the answer you think is correct." ”

"This ......" Ding Hai was caught off guard, after introducing himself, he still had to answer the question?

Ding Hai gestured to draw circles in the air: "It's spicy." ”

"How big is the spicy and how big, please elaborate, Ding Hai. For example, a football is so big, a basketball is so big?" Sun Erxiong prompted.

"Football is so big. Ding Hai said.

Sun Erxiong nodded and said with a smile: "The most correct answer is that if the apple is enlarged to the size of the earth, then the atoms in the apple will be as big as the original apple." Well, Ding Hai's answer is relatively close, please sit down. Don't be nervous, it's okay, I just said, it's just a common-sense test, a routine. Okay, let's ask Wang Sheng to introduce himself. ”

Wang Sheng stood up and introduced himself, my name is Wang Sheng, the king of the king, the victory of Sheng, from Hengshui Middle School......

A new common-sense test question was switched on the screen: "Which of the following substances is non-toxic: cadmium acetate, methylmercury, BAL, arsenite acid, yellow dandan, ?"

"This ...... After the physical test and chemistry test?is this a special common-sense test?" Zhou Yu'an began to complain again, "Seriously, I know that cadmium, mercury, and arsenic are poisonous, but what the hell are BAL and Huangdan powder?"

Wang Sheng hesitated for a long time and finally gave an answer: "Huangdan powder is non-toxic." ”

"Wrong. Shen Qi shook his head, "I also forgot what the hell Huang Danfen is, but I know that BAL is an antidote, I have this thing at home, and my mother got it back from the hospital." ”

Under the side of the curtain, Sun Erxiong smiled kindly: "The chemical formula of Huangdan powder is lead oxide, which is widely used in the production process of Songhua preserved eggs. Well, Wang Sheng's answer is very close, please sit down. By the way, the non-toxic of the five substances is BAL, that is, dimercaptopropanol, which is a chemical antidote for the treatment of heavy metal poisoning. Dear students, this is a general knowledge comprehensive test of the math camp, a routine, don't be nervous if it's okay. ”

"The general knowledge comprehensive test has nothing to do with mathematics, it is all about other subjects, which touches the blind spot of my knowledge. Zhou Yu'an habitually complained.

"Hey, Zhou Yu'an, have you found a pattern?" Shen Qi whispered vigilantly.

Zhou Yu'an nodded: "First Ding and then Wang, the fat instructor will come in the order of the surname strokes." Shen Zi 7 strokes, Zhou Zi 8 strokes, you introduce yourself in front of me, and you have to answer a random common sense question. ”

Shen Qi looked at the thin assistant in the corner who didn't seem to have much presence: "This is one thing, and the other is that the thin assistant is recording the answers to common sense questions." The fat instructor asked lightly, this is just a pretense, I guess they are secretly giving us a score. ”

Zhou Yu'an frowned: "The fat man is a smiling Yama, and the thin man is a ruthless judge, answer a question incorrectly, and terminate the contract and go home?"

Sun Erxiong continued to take the roll call and asked the other students to take turns to introduce themselves.

Wang Ruixin, Tian Zhiyuan, Jiang Yongming, Liu Junfeng, Liu Bolin, Li Huayang...... Sure enough, most of these students are from the top key high schools in the country, and all of them have won awards in various mathematics competitions.

The general knowledge test questions on the screen are constantly updated, such as physics, chemistry, biology, history, geography, literature, international and domestic news, ...... There are all kinds of fields involved, but there is no mathematics.

Some of the first ten people answered correctly, some answered incorrectly, the question bank was randomly sampling, and the general knowledge test questions were not esoteric theories, but the breadth of knowledge of the students.

At this time, Sun Erxiong glanced at the list in his hand, looked up and locked on a student in the classroom, his smile was bright and happy, his eyes narrowed into a slit and he smiled: "Next, let us welcome Shen Qi, the full-score champion of the United Nations Finals and the full-score champion ---of IMO, with the warmest applause!"

Hey, fat grandson, you have a lot of words, why did you finish all my lines, how can I pretend to be lightly. Shen Qi stood up and introduced himself: "My name is Shen Qi, I love learning, I like to read, I like to run, I have been to the king, I have written papers, and I am currently writing textbooks, all in all, I am very ordinary." Thank you, that's it. ”

"Shen Qi, you are not ordinary, you are very, very remarkable, welcome to Peking University!" Sun Erxiong applauded, and his music blossomed.

Bang bang bang.

The applause from the audience was warmer than just now.

"Knowing that he is an IMO champion, I never thought that I would be a king?"

"Wrote a thesis?"

"Writing textbooks?"

"I can't mess with it, I can't afford to mess with it. ”

The other students were talking.

"I'm an ordinary big guy Shen, and the invisible pretending to be the most deadly. Zhou Yu'an smiled and applauded, this wave was forced to give full marks.
