"Take the papers over."

Lin Kaiyu frowned.

The test questions in the first part of this paper are just the right ones, and the key is the last two additional questions.

These two additional questions were the Peking University Admissions Self-Study Questions last year. Originally, Lin Kaiyu took it out to screen students in the mathematics competition class.

The Jiangnan Provincial High School Mathematics League will start soon. Lin Kaiyu wants to see if there are any suitable math competition seedlings in the school besides the group of students set for the last semester.

Before, Tang Xiuyuan and Nie Xinyu said that Ye Qiu had the ability to remember everything, so Lin Kaiyu had the idea of ​​trying Ye Qiu into a good match.

So he simply took out the paper and gave a class test.

For high school students, these two additional questions are quite difficult and test a student's talent and comprehensive strength.

Even if the students in the competition class want to finish all the papers, they have to spend at least one class.

As for ordinary students, it would be quite good to finish the previous questions in one class, so don’t even think about additional questions.

But Lin Kaiyu never expected that now that he was halfway through, Ye Qiu said that he had finished answering everything.

Lin Kaiyu felt that Ye Qiu was either sensationalizing or could not do it, so he could write something casually.

Ye Qiu didn't know that Lin Kaiyu had a negative impression of him, so he walked to the podium easily and handed the test paper to Lin Kaiyu.

In an instant, the system's voice rang in Ye Qiu's mind.

[Congratulations to the host, who got full scores in the mathematics class test, the system unlocks the fifth super lottery number, 25]

Ye Qiu was stunned.

He suddenly realized that he would not look at how many points he scored, but the system had already completed the corrections at the moment he handed in the paper.

He suppressed his inner excitement, pretended to be calm and returned to his position, and hurriedly recorded the super lottery numbers.

0304071225!

There are two digits left in the back area.

We will try to get it done today, buy lottery tickets tomorrow, and repay a prize on the weekend, which is so wonderful!

Lu Wanwan, who was beside him, looked at Ye Qiu with joy and gritted her teeth.

She had just proved the first question of the additional question, but Lu Wanwan scratched her head a little.

She knew the calculation formula of ellipse, and even changed s=πab slightly. When a=b, s=πa^2 is actually equivalent to the formula of a circle.

But the question is, how to prove it?

Lu Wanwan lowered her head and thought.

...

On the podium, Lin Kaiyu glanced at the paper first, and it was very well written, but it was indeed finished.

Next, it will be formally corrected.

Fill in the blanks.

Question 1 is correct!

Question 2 is correct!

Question 3 is still correct!

After all the changes, the fill-in-the-blank questions were correct.

The next three questions are correct.

Especially for the last big question, Ye Qiu's problem-solving ideas are different from the traditional problem-solving ideas, but instead they are much more concise, giving people a feeling of sudden enlightenment.

Lin Kaiyu's face showed a look of surprise. This little guy has something.

However, doing all the previous ones does not mean anything, you have to look at the last two additional questions.

Lin Kaiyu turned over the test paper. These two additional questions were actually different from the extremely complex competition questions.

It also examines a student's ability to diverge his thinking.

Lin Kaiyu looked at Ye Qiu's proof process from top to bottom.

The surprise on his face became increasingly intense.

Whether it is the first or second question.

The proof process is concise and powerful, and the overall logic is flawless.

Especially in the second question, the proof of the elliptical area formula, Ye Qiu actually used the integral idea that could only be learned in college, but it did not exceed the scope that high school students could understand.

This kid is a talent!

Lin Kaiyu put away the paper and looked at the time.

It has only been thirty minutes since Ye Qiu handed over the paper almost five minutes ago.

In other words, it only took more than twenty minutes for this guy to finish answering this paper.

I'm afraid Ye Gaohui, who is in the competition class, may not be able to do this!

Lin Kaiyu thought to himself.

Ye Gaohui is a student in Class 2 (9) of high school and a famous mathematics genius at Jiangcheng No. 1 Middle School.

When I was in my first year of high school, I participated in the Provincial Mathematics League and won the first prize. I was successfully selected for the Mathematics Olympic Winter Camp to compete for the International Mathematics Olympics (imo).

Although he was not selected in the end, it is enough to show Ye Gaohui's ability.

This year, Ye Gaohui is even more ready to play. The Provincial League is no problem. He hopes to perform well in the winter camp and be able to represent China in the International Mathematics Olympiad, competing for gold and silver.

However, even if this paper is handed over to Ye Gaohui, Lin Kaiyu did not think that Ye Gaohui could finish all the answers in twenty minutes.

The following time is calm.

After the bell rang, the students handed in the papers one after another.

Lu Wanwan couldn't help but turn his head and ask Ye Qiu, "Have you finished answering all of them?"

"Why should I hand in the paper in advance if I don't finish the answer?"

Ye Qiu smiled.

Lu Wanwan said in surprise: "Have you proved the last question?"

Although she later found a specific idea for the last question, it was too late to prove it halfway.

"It's proven!"

"How did you prove it?"

Ye Qiu was stunned and couldn't help but smile and said, "What, do you want to learn?"

Lu Wanwan couldn't help Ye Qiu's burning eyes and turned his head: "I love to teach but not!"

Ye Qiu coughed dryly: "Let's do this, I'll tell you, just treat me to lunch at noon, and the cafeteria."

The hundred yuan he had on hand was the weekly meal money given by his mother, so Ye Qiu still wanted to save some money to buy lottery tickets.

After all, you can get eight million in just two dollars!

"you……"

Lu Wanwan didn't know what Ye Qiu was going to have. His pretty face turned a faint blush and he gritted his teeth and said, "Okay, I'll treat you at noon!"

"Then come here, I'll tell you in detail..."

Ye Qiu picked up the water pen and wrote and painted on the manuscript paper.

Lu Wanwan came over with her head, Ye Qiu shrugged his nose, and an inexplicable fragrance poured into his nostrils, refreshing his heart.

Ye Qiu was stunned: "What brand of perfume do you use?"

He had smelled a lot of perfumes in his previous life, but he never smelled this.

Lu Wanwan's delicate little face instantly turned red: "I don't need perfume! Do you say it or not..."

"Okay, okay, let's talk about the topic..."

Ye Qiu smiled embarrassedly, he knew what the fragrance was.

...

Lin Kaiyu took the paper and went straight to the grade office, while Tang Xiuyuan was chatting with several teachers.

Seeing Lin Kaiyu come in, Tang Xiuyuan smiled and said, "Old Lin, how is Ye Qiu performing?"

Lin Kaiyu smiled bitterly and said, "Old Tang, your class has really produced a genius, I am convinced."

Tang Xiuyuan couldn't help but be slightly stunned.
Chapter completed!
