I Am the Sister of the School Grass

    Yunyan stared at the clock on the podium, watching the second hand beat one by one.

    She sits at the back, and it stands to reason that she can't hear the sound of the second hand moving.

    But her heart beats involuntarily with the needle.

    Yunyan forced herself to withdraw her gaze. When she was highly nervous, she liked to cover it up with a daze.

    And many times she felt that she was not so nervous, but her body was very honest.

    Waiting for curls is always a long process.

    Being bored, he began to stare at the desktop and silently memorized the most basic formulas.

    Time passed slowly, and soon it was fifteen minutes before the exam.

    The invigilator on the stage read out the precautions for this exam in English.

    At the same time, translated text in various languages ​​appeared on the big screen behind him.

    These precautions are well known.

    Before they were in the training team, they heard Mr. Zhang mention the precautions several times.

    After all, answering the questions in the "simulated examination room environment" will also appropriately reduce the anxiety and tension of candidates.

    The answer sheet and presentation paper have been distributed and placed on everyone's desk.

    After the teachers read out the precautions for the test, seeing the last ten minutes before the test start time, several teachers looked at each other and removed the seal in front of everyone.

    Begin to hand out test papers to candidates column by column.

    This test paper is similar to the IELTS test. The first page is filled with the student's name, country, test number and seat number.

    Exam subjects and times are printed on the second line.

    The second half is the note again.

    There are still more than five minutes left after the paper is sent out.

    The teachers are naturally stuck in time again, emphasizing various matters again.

    In order to prevent everyone from breaking the rules due to personal habits, there will be a situation of "invalid roll score".

    There are many Chinese people, and one of the advantages of coming to the imo competition every year is that the pits in the precautions have been tested by the seniors themselves.

    Teacher Zhang has a lot of counter-examples.

    For example, before the invigilator announced that the test paper could be opened, someone saw that the time was up, and quickly opened the test paper.

    Then you will be taken out of the exam room directly.

    With so many 'predecessors' experience, everyone is even more afraid to take a step forward.

    Listen to the teacher on stage announce 'please-open-your-papers.'

    Yunyan picked up the prepared pen on the table and began to scan the three questions.

    After reading the title, Yunyan felt only one word 'new'.

    All topics are new and not at all familiar.

    After reading the first two questions, at least there is a general idea.

    But the third question, Yunyan didn't understand it the first time.

    But she doesn't know that this kind of test is to grab every point.

    Mr. Zhang emphasized over and over again, don't think about 'challenging yourself' and go crazy about problems.

    Because you will find that it is very likely that you will not be able to do this question by yourself until the paper is closed.

    The smartest way is to finish the questions you know first and check them two or three times.

    This will give you a chance to get a higher score.

    I have to say, don't look at Yun Yan's temperament, it seems that he doesn't care about anything.

    But she also has a common problem of being a scholar, and she can't take her eyes away when she sees a problem.

    But Yunyan can better distinguish the priorities of things, for an exam like imo, which has only a full score of 42 points.

    Very low fault tolerance.

    A point will be deducted for the slightest mistake.

    She weighed the difficulty of the first two questions and chose to start from the second question.

    Yunyan first calculated on the parchment paper.

    Half of it counts, no answer.

    At this time, more than twenty minutes have passed.

    Seeing that half an hour has passed, Yunyan feels really nervous and sweating.

    However, the temperature in the exam room is excellent and there is no wind.

    She is sweating now for no other reason than panic.

    Yunyan went to see the topic again, this time, she found a pit in it again.

    A new pit that did not appear in the previous exercise.

    Yunyan couldn't help rubbing her forehead, she sighed that she was all lucky.

    The first question was 'hit luck', and the most difficult of the three questions was chosen.

    As Mr. Zhang said before, the shortest and least demanding questions have a 20% chance of being simple questions.

    Most people can get points in this case.

    After all, the short title means that there may be fewer pits.

    If there is a big hole in such a short question, it can only show that the questioner has a high level.

    May I ask, will there be low-level questioners in the imo committee?

    Six questions are tested every year, and even after the test is completed every year, the whole world is rushing to imitate similar questions.

    Practice handwriting for your own students, and practice makes perfect.

    So, the level of the question maker has long been honed.

    Yunyan couldn't help sighing, she spent another hour to finish this problem.

    After checking the answer and finding it to be correct, it took thirteen minutes to transcribe the answer sheet.

    At this time, she went to the first question very quickly.

    Even the third question, which I didn't understand very well at first, was easily solved when I read it at this time.

    After all, the question is long, and the amount of information given is large, and it is easy for people to draw the test center within a certain range.

    Then according to the test center, the questioner wants to examine the content of everyone.

    In total, it took a total of 103 minutes for Yunyan sweeping and calculating and transcribing the second question.

    The first question only took 28 minutes.

    The third question also took 79 minutes because of the intention of the questioner.

    It took her three and a half hours to complete a set of questions.

    When brushing the questions, Yunyan has nothing else to do.

    After finishing the questions, I looked up, and the surroundings were almost empty.

    Yunyan: "…"

    Shocked, everyone is doing the questions so fast?

    Yunyan checked the answer twice, including every basic formula written on the answer sheet.

    After everything was correct, there were still more than thirty minutes before the exam, she raised her hand and handed in the paper.

    At this time, only about half of the people in the exam room were left.

    Mr. Zhang and other teachers from Hua Guo were sitting in the cafe opposite the examination room.

    More than 20 teachers occupy most of the cafe.

    Mr. Zhang asked everyone what to drink and what to eat as snacks.

    The answer was: "Just like you."

    I can't tell the difference after drinking it anyway.

    Besides, Europeans like sweets, and the dishes and cakes are very sweet.

    In the past few days, teachers have refreshed a lot of knowledge by ordering food by feeling, and decided not to step on the thunder.

    The walls of the cafe are made of glass, and the teachers all sit by the window, just to see when their students come out.

    The teachers trembled.

    "Are they doing the questions so fast? This, this is only three hours. Only Yunyan in our team has this speed."

    "Don't, don't, don't panic, they do the questions quickly, which doesn't mean the accuracy rate is high. Mr. Zhang has led the team for several years. Let's ask Mr. Zhang about the situation."

    Mr. Zhang covered his face, Mr. Zhang said he didn't want to speak.

    "Old Zhang?"

    "Mr. Zhang, what's the matter with you? Are you not feeling well?"

    Mr. Zhang is determined to share the discomfort with everyone.

    "In previous years, they also used the same speed. But in general, their total score in two days was around 25 points, and they didn't have to run for the silver medal."

    “…”

    After the silence, one of the teachers murmured, "Why don't you take this to heart, old Zhang?"

    Mr. Zhang said, "Don't worry, I'm not panicking at all this year. We have Yunyan and Xingwei, and the other four students are not bad at all."

    Two gold medals and four silver medals.

    He added, "Besides, those contestants who really get high scores in the test every year answer the questions and check them until one second before they are closed. Foreigners who answer half of the questions leave, usually The scores are not particularly high.”

    Mr. Zhang's voice just fell.

    I saw a very familiar figure coming out of the opposite building.

    Also wearing the national team uniform of China.

    Who else is Fang Yunyan?

    Mr. Zhang shook her hands and spilled the coffee.

    Then he hurriedly said, "Bah ah, crow's mouth."

    Yunyan is actually quite a character of 'do as the locals do'.

    She also submitted the papers ahead of time after the inspection, and there was no problem at all.

    However, Yunyan thought, should she go back to the hotel for lunch now, or wait for everyone to come out for lunch and sleep?

    The teachers are not allowed to stay in the teaching building, and Yunyan does not know where they are.

    Just as she was about to take out her phone and ask, a group of familiar people gathered around her.

    They looked at the clothes on Yunyan and sarcastically said.

    "You really are a Chinese monkey."

    These are the six teenagers I met at the elevator entrance on the first day.

    Yunyan is not worried about their actions, after all, they were so cowardly before.

    They are still at the entrance of the examination room. If they dare to do it, they may face the punishment of being sent back to China.

    Yunyan sent a message to Teacher Zhang on WeChat, "Teacher, I came out after the first exam, where are you, I'll find you."

    Then go to bed after the other students finish the exam.

    After she clicked send, she took a step back towards the security guard. After ensuring his own safety, Yunyan stopped paying attention to them.

    It's not that Yunyan is afraid of them, it's mainly 15 days before the exam, and it's okay to fight.

     She has to take exams these two days, and she feels that it is better to have less than one thing.

    Otherwise, if there is any conflict, it will affect me.

    Those teenagers took Yunyan's retreat as fear.

    "Are you afraid?"

    "A yellow-skinned monkey is a yellow-skinned monkey, no matter how good-looking it is."

    As soon as a boy finished speaking, a tall figure appeared beside him.

    The man used his strong eyebrows to make him dare not say the next words.

    Yuan Mo was wearing a suit, and his temperament was very oppressive, and his eyes were cold.

    Let those teenagers not dare to do it again.

    The person who was a little further away from him dared to ask, "Who, who are you? This is the entrance of the examination room, you can't do anything..."

    Yuan Mo's voice is very cold, his English is very standard, with the restraint in the tone of British aristocrats.

    "Guanguo people? Didn't your teacher Wido teach you to respect players from other countries?"

    When the teenagers saw him, they could say their teacher's name.

    All of them were stunned in place, not daring to make mistakes.

    Their teacher Widow is a grumpy old man who has tried to 'beat' to educate students.

    Because of the cultural habits of various countries, their elders have unlimited power.

    I really want to be known by Teacher Widow, and I will definitely be beaten when I go back.

    Yuan Mo's indifferent eyebrows swept the panic in the eyes of the six people, "Apologize, then, get out."

    After the six teenagers apologized in turn, they walked away in despair.

    The security guard glanced over here, then turned away, and patrolled other places.

    Yunyan looked at Yuan Mo, her eyes widened instantly, and walked to him in three or two steps, "Brother Mo, why are you here?"

    The expression on Yuan Mo's face softened.

    He said, "Meet."

    "What a surprise." Yunyan's eyes were full of smiles, and the defenses he had just faced with the teenagers were gone.

    Yuan Mo took the pure surprise and happiness on her face into his eyes, the ninja sighed, and said, "Little Fang Yunyan, can I make a small request for you."

    Yunyan didn't know why, but the slightly raised chin was lightly tapped.

    She really can't think of what more requests are needed for such a powerful **** in Mexico...

    Yuan Mo gave her the tangled hair on her cheeks and put it away from her ears, with a clear voice, "Don't call me teacher again, and don't send me the message you want to send to the teacher. ,it's OK?"

    He just told the little girl some Orsay tricks.

    How come she has always been recognized as a teacher?

    Yuan Mo thinks, there is a big mistake in this cognition.

    Yuan Mo's words were like exploding in his ears, Yunyan quickly looked at his WeChat.

    Sure enough, the message I planned to send to Teacher Zhang was accidentally sent to Yuan Mo.

    Yunyan quickly explained, "I was just paying attention to the group of boys, but I didn't pay attention..."

    When Yuan Mo saw this scene, he could probably guess the reason.

    But God knows how flustered he was when the little girl's sentence 'Teacher, I finished the test' popped up in his WeChat.

    Yuan Mo really doesn't want to be promoted at all.

    Yunyan pondered for a while, and said, "Then I will make up for it and invite Mexico to dinner later?"

    Yunyan felt that Mexico himself was not a few years older than himself.

    The title of 'teacher' may be a bit like an elder, so he will not like it, and he has repeatedly emphasized that he should change it himself.

    However, seeing the always indifferent Yuanmo boss lower his body, it really made Yunyan feel guilty and uneasy at the same time.

    Even Yunyan couldn't tell what the current anxiety came from.

    About an hour and a half later, Yunyan had dinner with her teacher, classmates and Mexico.

    She is still thinking about it.

    Yunyan is very smart, she may not be sensitive to emotional matters.

    But she can rationally and objectively analyze the change of a person's attitude.

    Finally, Yunyan blamed her uneasiness on... Mexico's attitude towards herself seems to be a little different from before.

    As soon as this thought came out, Yunyan felt that her initial anxiety was a little too strange.

    Mexico treats himself a little better, and he will definitely treat him doubled.

    No worries.

    Thinking about it, Yunyan can eat more happily.

    Qian Xingwei sat beside Yunyan, he had seen Yuan Mo before.

    In the Northland, during the training of the national training team, Yuan Mo often took Yunyan out to play.

    After playing for a day, Yunyan can always come back with some exquisite food, and share it with everyone the next day.

    Qian Xingwei didn't know his identity, listening to Yunyan calling him 'brother' and 'Mexico'.

    Even Teacher Zhang sees him and occasionally wants to force him to go to the classroom to talk about some topics for everyone.

    Once Qian Xingwei went out for dinner, he accidentally bumped into this incident.

    Then he heard the man's faint rejection.

    Mr. Zhang was stunned, "No, Yuan Mo, you were not such a secretive person before."

    The man said: "That's because you don't know me. I am a person who likes to keep secrets and is very careful."

    Afterwards, Qian Xingwei took the lunch box and walked away without hearing what they were saying.

    I don't even know the fundamental reason why Yuan Mo doesn't want to give lectures is that he really doesn't want to be a teacher.

    Besides, he wasn't the little girl's teacher.

    On the way back, Yuan Mo told Yunyan about the various delicacies here.

    Yunyan does not have high requirements for food, at most she likes the food made by her grandmother.

    So, as long as you can eat food with familiar taste, Yunyan likes it very much.

    As for other delicacies from the mountains and seas, Yunyan doesn’t have so many ideas yet.

    Yunyan cares more about Yuanmo's colloquialism, and the tone of voice sounds very expensive.

    Even people like Yunyan who don't watch European and American dramas like it.

    When Yuanmo talks about food, Yunyan says "um" and "ah", the next sentence is, "Mer, how do you practice your spoken English, do you have any tips?"

    Yuan Mo watched the little girl stand up, with a slight admiration in her tone.

    He said his heart was cold.

    Yuan Mo felt that if Yunyan children were thicker-skinned, he would say, "Merco, can you teach me spoken English?"

    Yuan Mo never wants to be a teacher in this life.

    He swears.

    However, Yunyan only wants to learn.

    Even if Yuan Mo doesn't want to teach at all, he can only pretend that he is happy to share a bunch of skills.

    Yunyan Xiaolian listened very seriously and nodded frequently.

    Finally, "Thank you for your guidance."

    Yuan Mo felt a mouthful of old blood stuck in his throat.

    Yunyan said, "I will cook a feast for Mexico after returning to China. I will learn to do what you just said."

    Yuan Mo: "…"

    In fact, Yuan Mo was not very sure of his own thoughts. He started to take care of the little girl as his sister.

    However, the work in the secret base in those days made his 'emotional' emotions continue to brew and ferment.

    Even Yuan Mo himself is not sure if this is—

    Like.

    On the second day of the exam, Yunyan did the third question after scanning the questions.

    Although this question is the most difficult question recognized by the committee, it is a new question type that Mr. Zhang said was reformed this year.

    It combines logical thinking and spatial geometry derivation, and it is also a little bit related to the restoration of the Rubik's cube.

    Yunyan looked at this question, but felt very kind.

    Even if you didn't guess the question type, but the knowledge point is there, this question is almost solved.

    It took less than two hours to complete the three questions on the paper today.

    After she finished writing, she looked up and was surprised to find that everyone in the examination room was still there.

    Yunyan is really a person who is easy to follow the crowd. In this case, she chose to check the test paper several times.

    The first person to hand in the paper and leave the examination room will be the first person to pass the examination for the third time.

    It was at this time that Yunyan discovered that there was a hole in the title of the third question.

    Yunyan's heart twitched.

    It's less than an hour before the end of the exam.

    Yunyan hurriedly re-transcribed the calculation, and almost three minutes before the rewinding, did he copy the recalculated answer.

    She is the only one left in the entire examination room at this time.

    The teacher passed by the only student during the inspection tour and found that she was using a black pen to erase the wrong answers she had copied before...

    The entire answer sheet is jet black.

    Teacher: “…”

    Suddenly feeling suffocated.

    It wasn't him who was marking the papers anyway, so that's it.

    After going out, Yunyan heard the correct answers from the people around her.

    Speaking English, she can understand a little bit. As for the languages ​​of other countries, Yunyan's eyes are completely dark.

    She heard English-speaking candidates discussing the answer to the last question around her.

    "It must be a heptagon. That trajectory is finally derived like this."

    "Ah, I didn't write this question, so I don't know how to play Rubik's cube."

    "Although I don't know much, but it is a heptagon by blind deduction! Ah, holy...Bless, I actually wrote this inscription correctly!"

    Yunyan's lips twitched physiologically, ready to go downstairs.

    Qian Xingwei also persisted until one second before the rewinding. As soon as he walked out of the examination room, he saw a cloud of smoke through the crowd.

    He caught up with three steps and two steps, and asked, "Yunyan, your last question is also a heptagon?"

    There is a feeling of the rest of your life in Yunyan's eyes.

    She looked at Qian Xingwei and slowly shook her head.

    Qian Xingwei's eyes suddenly burst into a smile, making a 'nine' gesture.

    Yunyan nodded tacitly.

    The two walked out of the teaching building side by side talking and laughing.

     "That question is too deep, and the wrong algorithm can fully deduce the result, which is too embarrassing."

    Yunyan was also very emotional, "Yeah, I changed it at the last second, and I was terrified."

    The moment she walked out of the glass door, Yunyan saw Yuan Mo standing under the steps.

    She waved at Yuan Mo and wanted to run towards him.

    Leave a message with Brother Wei, "I may not have dinner with you today. Help me to tell Teacher Zhang and the others, thank you Brother Wei."

    "Clouds..."

    Fang Yunyan turned her head, "Huh?"

    "Be safe."

    Fang Yunyan smiled at him, "Don't worry, Brother Wei, I'll be back in the afternoon, everyone said it's good to see London Bridge."

    imo the results of the competition are also very fast, basically everyone will be able to see their results tomorrow morning and get a medal.

    Yunyan jumped down the four steps in front of Yuan Mo, her eyes seemed to be carrying stars.

    "Mexico."

    Yuan Mo heard her last words, "Play with the teachers in the afternoon?"

    "Well, Mr. Zhang said to take us for a walk."

    Yuan Mo originally wanted to decide whether to sit on the London Eye together at night.

    But when I think about it, it's mid-July, and the days in the UK are lit three or four in the morning and dark at ten o'clock in the evening.

    You can't see the night view from the London Eye.

    Not to mention that Big Ben is still under repair and can't see anything.

     Yuan Mo said, "Then I'll have to wait for winter to bring you to sit on the London Eye."

    Yunyan doesn't know much about the culture here, but she trusts Yuan Mo and says, "That's right, because of the paper I sent before, I have received a lot of invitations in my mailbox recently. Eleven There will be a Turing code-themed seminar in Manchester in January, so I don't have to worry about my visa."

    Yuan Mo thought to himself, are you still worried about visas?

    As long as imo gets the gold medal, at least two years of multiple entry and exit visas can be given.

    No worries at all.

    However, listening to Yunyan talk about his future plans, Yuan Mo actually found it very interesting.

    Soon, it will be the morning of the results.

    The International Mathematical Olympiad Awards Ceremony is not held in a stadium like the 'Olympics'.

    Instead, it was held in the Great Hall of King's College.

    Yunyan wore the clothes of the Huaguo team and stepped into this castle-like auditorium.

    The red carpet all the way, solemn and solemn.

     At nine o'clock, the award ceremony officially started.

    imo the old man standing on the podium of the committee doesn't do those fake things, and just puts the results and rankings.

    Only one person's grades and rankings are shown in the first one—

    1,,china,42

    The old man 'wooo' said, "This is the third full score since our imo competition was established! Let us congratulate Hua Guo, Yunyan Fang!"
