In the second year of high school, there are only Liu Xun and Xue Tian in the first class, Jiang Yu, Xu Zekai, and Du Juan in the eighth class, and Wei Chengxiang in the sixth class. None of the others were selected, Lin Xuejiao's original grades were okay, but the performance of the small test at the beginning of school was not good, and she was brushed down by the old horse.

No. 1 Middle School is a century-old school, with a strong cultural atmosphere, the campus is full of towering trees, seven or eight people can hug the big trunks, the sun shines from the canopy, falling mottled light and shadow.

Before the exam, all students have to wait on the lawn opposite the teaching building, waiting for the bell to ring, and generally enter the exam room half an hour in advance to find the exam room.

Xue Tian was wearing a snow-blue pullover sweater, jeans, and only a transparent document bag in his hand, in which there was a set of rulers, a compass, two gel pens, two 2B pencils, erasers, and bicycle keys in his pants pockets, not even a mobile phone.

Many students were carrying schoolbags and reading with scrolls in their hands, and Xue Tian's simple equipment seemed a little out of place in the crowd.

Lao Ma saw it but thought it was very good, everything that should be prepared was prepared, and when he went to the examination room, what books did he read, it would affect the mood of the exam.

Lao Ma just wanted to say something to Xue Tian, because he found that Xue Tian didn't seem to be familiar with the big guys, and everyone talked to her.

As a result, I heard several students wearing a middle school uniform next to me chatting, and the girl with acne in a ponytail smiled and said, "You say, how many first places can our school have?"

The short-haired girl smiled and said, "Forty-three last year, and this year is estimated to be about the same." ”

The third girl was a curly-haired girl, and she said, "How many people from our school can enter the CMO training camp this year?"

The short-haired said: "In the second test last year, there were ninety first places in the country, nine in our school, and then eight were brushed down one after another, and one person was left to the end, participated in the international CMO, but only won the silver medal, but this is also very honorable, this is a global event." ”

The long ponytail smiled and pointed to the students of the experimental middle school wearing school uniforms on the side and whispered: "The experimental middle school over there, you see that their school uniform is quite good-looking, did you see that boy, it is still a big brand of watches, but unfortunately it is useless to wear it well, how many years have they experimented, there are very few people who won the first place in the second test, I heard that there was no one in the first place in the second test last year?"

The short-haired one said: "Yes, I shaved my head last year, and I had one the year before last." ”

The old horse's face was red, and he felt the slap on his face, oops, it hurt.

So Lao Ma couldn't help but say to Xue Tian: "Xue Tian, you work hard, fight for the teacher, you must enter the training team, and when the time comes, the teacher will give you a big red envelope!"

Xue Tian's eyes lit up: "Really?"

Lao Ma suddenly felt speechless, talking like this, it would put too much pressure on the students, Lao Ma didn't explain it here, he heard one of the three girls with a ponytail snort and laughed: "Hey, I said that your experimental middle school is too funny, and you also entered the training team, do you think it's to buy vegetables, anyone can enter the training team?"

Lao Ma's face was flushed, he was a teacher, and he didn't want to be serious with these students, so he turned around and didn't speak, Xue Tian said very seriously: "Is it difficult?"

The long ponytail raised his head and said proudly: "Of course it's difficult!" After the long ponytail finished speaking, he was about to say something, but Xue Tian took the first step to speak: "I don't think it's difficult!" and then turned around.

The long ponytail choked, and she didn't know what to say for a while, seeing that Lao Ma and Xue Tian had turned around, it took a long time for her little friend to start chattering again, and she looked at Xue Tian from time to time, as if she wanted to remember this girl.

I entered the examination room at half past eight and started at nine o'clock.

There are twenty candidates in a class, two invigilators, but three Xue Tian, two in their thirties and forties, and one in their fifties and sixties.

The roll was sent down, but the time has not yet come, and everyone can only look at this roll.

Xue Tian looked at the multiple choice questions in front of him, one by one mental arithmetic, and the exam started in ten minutes.

Xue Tian picked up the pen and checked the first ten questions, and then began to do the later questions, Xue Tian checked it in such a fit that the older teacher in front saw it at a glance, and couldn't help but widen his eyes.

So the old man walked over slowly and stood behind Xue Tian.

Several students around him instantly became nervous.

There are a total of 30 multiple-choice questions, the first ten questions are calculated by mind, and when you can answer the sheet, you can directly check it out, and the back questions, scan to do one, the speed is very fast, and it didn't take long to start writing calculation questions.

Calculation questions need steps, but some of the middle operations need to be written on the scratch paper now, but Xue Tian wrote as if he had calculated in advance, in strict accordance with the requirements of the exam, three steps, and then the result.

In this way, one question in two minutes, the speed of one question in two minutes, and the appearance of half an hour, I began to do the last four big questions.

There are a lot of calculations in the first three questions, and Xue Tian wrote them directly on the scratch paper in order to make the volume neat.

The old man was standing with a pain in his back, and two teachers hurriedly brought a tall square stool and helped the old man to sit on it.

Xue Tian sat on the roll and didn't react to the sound at all.

The old man watched Xue Tian write the correct answer on the scratch paper, and then copied it neatly on the scroll with the calligrapher, the writing was smooth, and it looked like a printed font.

The old man nodded his head.

The next two questions went well, but when it came to the last question, Xue Tian stopped.

The old man couldn't help but smile when he saw this, and he had a little pride in his heart, he said, well, how can the paper he came out be so simple, it's only an hour, this little girl still has a big question to finish, and the last finale is the big question of the last trial of last year's CMO training, and the numbers have been changed.

Not long after the old man was proud, Xue Tian began to write, in fact, it was not that she couldn't do it, it was that she had already dabbled in college mathematics, and this problem required at least two methods to solve the problem, and Xue Tian could solve the problem in at least four ways.

However, you can write up to two questions on the last question.

And where Xue Tian planned how to use the rest of the volume to write four questions.

So Xue Tian took the ruler and began to plan on the last side of the paper, there are too many points that need to be argued to do questions with their high school knowledge, the area needs to be the largest, and the competition knowledge is a little less, and using college mathematics to do problems occupies the least space, and she also has a side-pushed argumentation method, which is an argument that already exists in their previous life.

She needs to elaborate this argument before she can do the question, so that it occupies the least amount of land.

Next, Xue Tian wrote three words "first" at the top of the largest position

Then start writing the solution steps.

The old man held his eyes and looked at it carefully, there are four plates, the first plate is written the first type, so what about the remaining three plates? Is there four ways to solve the problem?

The old man shook his head, impossible, he has tried, at most three, which also involves some knowledge points of university mathematics, most children have not been exposed to it, but I am afraid that at most two kinds of columns can be written.

But half an hour passed, and the old man watched Xue Tian write four methods.

The fourth method is preceded by a paragraph of inference, and then the method of solving the problem.

The old man stubbornly endured the curiosity in his heart, and waited for Xue Tian to finish writing the paper, and slowly finished the answer sheet, then he grabbed the paper and turned to the last page and read it carefully.

Xue Tian glanced at the strange old man, didn't speak, and began to recall all the test questions on the paper to the calculation paper.

After reading the last question, the old man was like a dumb man, and he couldn't make a sound, but time was running out, he was here to inspect the exam, why did he sit in a class for nearly two hours.

So he hurriedly glanced at Xue Tian's name and school class, and hurried out.

After the strange old man left, Xue Tian checked the papers, handed in the papers twenty minutes ahead of schedule and went out.
