Yuhang, Mingsheng Lake, Xu Chuan looked at a lake with clear water.

The quiet lake is like a treasure mirror inlaid with jade, reflecting the sky, the clouds, the bridge, and the people.....

In the early spring of March, Mingsheng Lake still has a little chill, but the willows by the lake have shown new buds, showing a touch of tender green, just like the words of the ancients, 'fine willows are easy to weave tobacco, and the shadow of the birds is difficult to stay on the green screen'.

Xu Chuan is the first time to come to the West Lake, and there are not many people who come to travel in this season, but the scenery is picturesque and can wash the soul.

Willow branches sprout, three pools of the moon, beautiful scenery and fireworks connect the fairyland with the world.

But it didn't last long before someone around me broke the silence.

"Brother Chuan, how bold do you say Xu Xian is? Dare to play with snakes. ”

"Brother Chuan, Brother Chuan, do you say that Fahai likes his family's white lady? Otherwise, how could she have been imprisoned for so long? ”

"Brother Chuan, Brother Chuan, this sister of Suzhou and Hangzhou is not afraid of the cold, she will wear a skirt with bare legs in early March."

"Brother Chuan, Brother Chuan, do you say that this lake is not deep, can it drown people?"

“......”

After a year, the little round-faced Lu Tianrui has not changed at all, and he is still the 100,000 whys that he walked.

Unlike the last time in Bashu, this time there were other members of the national group, and some questions about the small round face caused heated discussions.

"What is Xu Xian, Ning Caichen is a true warrior."

"Fahai loves Xiaoqing!"

"He loves a p Xiaoqing, he loves Xu Xian, and imprisoning the White Lady is just to fly with Xu Xian."

"You can't say that, Fahai said I want it!"

"Fahai has imprisoned the White Lady for twenty years, twenty years, everything that needs to be done has been done, right?"

"Xu Xian is miserable, twenty years, the children are at least eighteen (ಥ_ಥ)"

“......”

Xu Chuan glanced at this group of people, what are Xu Xian and Ning Caichen, Sun Wukong and his father are called a.

.......

After visiting Mingsheng Lake, the group returned to Yuhang No. 2 Middle School.

For the students who participate in the national market, the leisure time is rare, the national market is different from the provincial market and the school market, the national market will talk a lot of things every day, and will sort out all the high school knowledge from beginning to end.

In this process, each knowledge point will be tested, and then the strongest will be screened step by step.

To put it simply, there are test papers to do every night, and they have been done for fifteen days, and then the six people with the best results are selected to form the national team.

Although there are exceptions, the selection of people by the National Assembly is roughly one such path.

The next day, at 8 o'clock in the morning, the 60-member mathematical training team completed the first assembly in the auditorium.

On the stage, Academician Zhang Weiping, director of the Mathematical Society, looked at the students in the audience, whose faces were still a little immature, but they bore the hope of the future.

These 60 people are the elite selected from nearly 10 million candidates, if nothing else, in the future, they will play their own light in their respective fields and contribute their own strength to mathematics and the country.

But now, the moment that will decide their fate has just begun.

After clearing his throat, Zhang Weiping took the microphone on the table: "I am very happy to be sitting with all of you today, and I am also very happy to lead this session of the National Competition." ”

"To stand out from several mathematics competitions and stand here, your talent and efforts are undoubtedly worthy of recognition."

"But that's not enough, it's not enough, not everyone will be in the national team to represent the country, and in the next twenty-five days, most of you will be eliminated."

"And the remaining six people will undertake the mission of winning glory for the country, and will fight in the examination room with the strongest students from other countries in July this year to compete for the golden medal!"

"It's an honor, but it's also a responsibility."

"The opportunity is in front of all of you, and it's fair to each and every one of you, but it requires your best efforts."

"Come on, young people, you are the future of the motherland! Please also let the motherland see your future! ”

......

After a short speech, the tense and exciting national competition was officially opened.

Sixty Guoji students gathered in a large classroom, and a professor in the field of geometry stood on the podium and began to intensify the teaching of knowledge in the field of geometry.

Generally speaking, the competition scope of the IMO International Mathematical Olympiad includes four categories of test points: geometry, algebra, number theory, and combinatorics, but sometimes some probabilities are tested, but all the questions in the exam are not outside the recognized range of intermediate mathematics.

For Yu Xiaguo in the ninth district, one or two professional coaches are arranged for each of these four categories to guide and strengthen.

Coach He, who teaches geometry, talks all morning.

From 9 a.m. to 11:40 p.m., more than two and a half hours were spent in the middle of the meeting, and students were only given 10 minutes to address their personal physiological needs.

The rest of the time, the whole process is to explain all kinds of geometry knowledge points, starting from the most basic foundation, and then the difficulty has been climbing.

Professor He explained the knowledge quite quickly, and he had already turned nearly half of a special textbook in the morning.

Quite rich old people in the style of class.

Anyway, I'm talking about my own, and I don't care how much you can understand and absorb.

At noon, class ended at 11:45, an hour and a half of eating and lunch break, and in the afternoon, a new geometry professor was replaced, and he began to question, test and explain the geometry knowledge points explained by Professor He in the morning, which was considered to be consolidated.

The training intensity of Guoji is very high, but it is a cramming education, and there are teachers in the afternoon to explain and consolidate the knowledge learned in the morning.

But if you want to say that it's not cramming education, at the end of this day, no, or in the morning, what you have to learn is almost a small semester of high school a year.

The knowledge that was originally learned in three months is now all crammed into your brain in one day, which is more devilish training than devil training.

On the afternoon of the first day, a slightly weaker student couldn't bear this kind of knowledge indoctrination method of stabbing you in the brain with a pipe, like instilling feed into a Round goose, and fainted, and was carried out by the medical staff who were always on standby outside.

At six o'clock in the afternoon, the devilish training camp ended, and dozens of students of the training team who were physically and mentally exhausted finally ate a hot meal.

On the Hunan side, except for Xu Chuan, Lu Tianrui and a few students who participated in the training camp last year, the other students were already stupid.

These competition students who entered the national market for the first time, where have they suffered such a high intensity of training, and the intensity of the school and provincial markets is not even one-third of this.

Although a lot of geometry knowledge has been learned before, it is really difficult to keep up with the speed of Professor He's explanation.
