Twenty minutes later, Ling Xuan and Guo Zidong raised their hands at the same time.
"Teacher, hand in the paper."
He Longchang: "?" It's only fifty minutes.
It seems that 4.5 hours gave a lonely.
Another ten minutes later, Wei Kongjue, Wu Pingting, Chen Cheng, and Tan Jiaxu handed in the papers.
after coming out—
Chen Cheng asked, "How do you feel?"
Tan Jiaxu: "It's not that difficult."
Chen Cheng: "It seems that we have to be vigilant this afternoon."
Tan Jiaxu's eyes suddenly froze.
The first three questions are mediocre, but the last three questions are bound to widen the gap.
The two went to the cafeteria, Jiang Fuyue and Ling Xuan had already prepared meals for them, and after finishing their meal, they ran to the dormitory.
There are still five hours before the exam starts in the afternoon, which is enough for them to do another set of questions and take a nap.
…
In the office, He Longchang came back with the test paper in his arms.
Li Zhao: "So fast?"
He Longchang: "The questions are simple, and they were handed in in advance."
Xiang Pengyi chuckled lightly, implying: "I hope they can be so relaxed this afternoon..."
"Right, ask me something."
"you say."
He Longchang: "That Jiang Fuyue doesn't use scratch paper for the questions?"
Li Zhao nodded: "I found out on the first day."
Yuan Bentao: "When I wake her up in class, she can give the answer directly. When I ask her how to do the math, she says that her brain will come up with the answer directly."
He Longchang was speechless for a while: "... this student does have two brushes."
In the afternoon, the examination room remained unchanged.
It's just that the difficulty of the topic is more than a little bit worse than that of the morning.
The first question made everyone stare blankly and scratch their heads.
Let z1, z2, z3 be 3 complex numbers whose modulus is not greater than 1, w1, w2 are the two roots of the equation X=0, prove that for j=1, 2, 3, min... is less than or equal to 1.
This question looks like an algebra question, but the first thing everyone thinks of is the geometric method, because the teacher taught it this way, and they have encountered similar questions in the previous quiz training.
Everyone didn't even think about it, they just thought about it in the direction of geometry.
But the further down the steps, the more confused the expressions on everyone's faces—
Why is it different from usual
Is there a discrepancy with what the teacher said
The most deadly thing is that I can't do it halfway!
Everyone was dumbfounded.
When Jiang Fuyue got this topic, she immediately compared it with the previous ones in her mind, and sure enough, it just looked like it.
In fact, it is two different things!
Because of the lack of a condition and the addition of an equation restriction, this question has changed in essence, and can only be solved by algebraic methods or algebraic plus geometric methods.
Pure geometry doesn't work.
Besides, Chen Cheng and Tan Jiaxu, when they got this question, their first reaction was geometric method, but before writing, I remembered Jiang Fuyue once said: "If they are not exactly the same, don't say two questions."
Sure enough, there is one more equation constraint!
The two dared not be careless, and tried to use the geometric method on the draft paper. As a result, they saw the clue in the second step, and quickly reversed the direction and adopted the algebraic method.
Here I have to mention a sentence that Jiang Fuyue said before: "In addition to pulling the cart with your head down, you must also learn to look up at the road, because the direction is more important than hard work."
Jiang Fuyue spent ten minutes on the first question.
When Yuan Bentao heard the voice while turning the page, he couldn't help but glanced at her, and immediately raised his eyebrows.
Is it done
Still can't do it and plan to skip it
Coincidentally, the second question still examines algebra.
It's about the reverse Cauchy inequality on convex sequences.
It was originally obtained by Alzer, a mathematician in country D. Later, the research was refined, attracting many mathematics experts, and more and more research results.
Coincidentally, Jiang Fuyue has read related papers and knows many proven conclusions.
One of the derivation theorems is just related to this question. If it can be used directly, then this question can be easily solved in only three steps.
Unfortunately, IMO has requirements, and only high school knowledge can be used to answer the questions.
Even the theories of calculus and linear algebra cannot be used directly.
It is not impossible to use it, but the existing high school knowledge must be used to complete the proof or derivation on the spot.
Jiang Fuyue was silent for a moment, well, the derivation process is quite cumbersome.
Ten minutes later, she asked for additional papers.
Yuan Bentao paused: "What's wrong?"
Jiang Fuyue: "Not enough to write."
In the end, Yuan Bentao added a blank page to her on the spot.
Others: "?" Which question is so perverted? How could Jiang Fuyue ask for additional papers
Hmm... It seems that I have no more confidence.
Jiang Fuyue spent a full twenty minutes on this question.
Not only did it densely fill up the original blanks of the test paper, but it also filled up the page of Tim with eloquence.
When the inspector passed by her, Yuan Bentao was shocked at the first glance.
Does the second question require so many steps
No!
What is she doing
On the contrary, the third question was the easiest, and Jiang Fuyue only spent eight minutes on it.
So, 38 minutes after the exam started, Jiang Fuyue raised her hands again...
In an instant, the examination room gasped one after another.
Grass! Why is it faster than in the morning? dying!
I just want to ask, is she still human? !
I want to open her brain to see what structure is inside and how it is different from ordinary people.
Seeing Professor Yuan's dumbfounded look, I regained my balance.
…
Ling Xuan came out two hours after the exam started.
When everyone was shocked by Jiang Fuyue's early handing in of the paper, and their mentality was slightly broken, Ling Xuan didn't raise his head, and wrote with intent.
After all, I have long been used to it.
I am calm when others are afraid, because the devil is by my side.
If you are frightened, you will become bolder.
Chen Cheng came out three hours and fifteen minutes after the exam started, more than an hour later than Ling Xuan, but judging by the expression on his face, the degree of completion should be quite good.
Tan Jiaxu also came out five minutes later with a smile on his face.
The four of them did not exchange questions, nor did they ask Jiang Fuyue for an answer.
Chen Cheng: "The exam is finally over!"
Tan Jiaxu: "After a week of hard work, I can finally sleep well tonight."
"When did Guo Zidong and Wei Kongjue hand in the papers?" Jiang Fuyue asked suddenly.
Both of them were in the second examination room, she didn't know.
Chen Cheng: "I don't know. Anyway, when the commendation came out, they hadn't handed it in yet."
Jiang Fuyue curled her lips slightly: "Very good."
Tan Jiaxu and Chen Cheng looked at each other with a tacit understanding.
That night, Ling Xuan treated guests and took them to a big meal outside the school.
As expected of the young master of a wealthy family, he is generous in his actions, and he directly prepares western food, and he is also one of the three most expensive houses in the imperial capital.
Chen Cheng: "Ah, it's nice to have money."
Tan Jiaxu: "Hi! This damn smell of copper."
When we came out after eating, it was already dark, the street lights were dazzling, and the neon lights were flickering.
The four of them were about to take a taxi back to school when Jiang Fuyue suddenly answered the phone, and after saying hello twice, she said that she would not go back for the time being and let them go first.
Ling Xuan frowned: "It's not safe for you to be alone."
"Don't worry, I have a measure."
Ling Xuan knew he couldn't persuade her: "Call if you have something to do, don't be too late."
"good."
The three of them got in the car and left.
Five minutes later, a black Mercedes-Benz stopped in front of Jiang Fuyue.
She opened the door and got into the co-pilot.
Xie Dingyuan: "Congratulations."
Jiang Fuyue raised her eyebrows: "What do you mean?"
"IMO gold is in sight."
"Now even the national team list has not been announced, and you congratulate me on winning the gold? Is it too early?"
"Tell me in advance, I'm afraid I won't have a chance then."
Jiang Fuyue was slightly surprised: "What's wrong with you?"
It was only then that she noticed that the man's face was tired, and the corners of his eyes and brows were full of fatigue. Because of his fair skin, the dark circles under his eyes were particularly obvious.
On the phone just now, he also said that he must see her, and his attitude was very firm.
In fact, Jiang Fuyue was somewhat dissatisfied.
But now it seems...
The man's Adam's apple rolled slightly, and his low voice revealed a hint of hoarseness: "Tomorrow I'm leaving for Continent F, at least three months, at most half a year or even longer, I may not be able to witness the moment you wear the gold medal, so, in advance Congratulations."
"Continent F? Are you on a business trip?" But as far as she knew, Hanqing had no business sector there.
Xie Dingyuan shook his head.
"That is?"
"…Sorry." He couldn't say.
Jiang Fuyue naturally wouldn't force it, "Okay, I'll accept it."
The man smiled slightly: "And this."
Then, as if by magic, he brought out a bouquet of roses.
"Is this also delivered in advance?"
"Um."
"Okay." Jiang Fuyue took it like a stream of kindness, and held it in her arms.
When I bowed my head for a moment, the fragrance of flowers was lingering.
Suddenly there was a click—
She raised her eyes in astonishment, and said again, this time the flashlight was still on.
It was Xie Dingyuan who took out his mobile phone and took pictures of her.
"you… "
"It's beautiful, I'll send it to you."
As soon as the words finished, Jiang Fuyue's WeChat chat vibrated twice.
It was sent to her.
The man put his phone away and held onto the steering wheel: "I'll take you back to school."
Xie Dingyuan came in a hurry and left in a panic.
It seemed that this trip was really just to say "Congratulations" to her personally.
Oh, and this bouquet of roses.
Doubt flashed across Jiang Fuyue's eyes, but she turned around and entered the school gate without thinking too much.
The results were announced the next day, and all 34 members of the training team were present.
The teacher hasn't come yet, and the whole classroom is chattering.
Chen Cheng: "Did you watch the news this morning?"
Tan Jiaxu shook his head: "What? Did something important happen?"
"It is said that an unknown virus has appeared in Continent F, which has caused more than 200 deaths. The Taki government urgently asked Huaxia for help, hoping to send a team of experts..."
