I Am the Sister of the School Grass

"Mr. Zhang, there is no homework today, right?"

Mr. Zhang really thought that everyone was praising him and smiled.

"Yes, I also think this way of outing is very unique and very educational. There is no homework today, we will go to the next school tomorrow, and everyone will speak on the stage. Brothers and sisters are listening from the audience."

“…what?”

Someone asked tremblingly: "Teacher, do you really plan to let us teach the Olympiad to the brothers and sisters of Tsinghua University?"

Mr. Zhang is very confident in everyone.

"Yeah, don't worry too much, how many people can be recommended to Tsinghua? At least you are all recommended, show your self-confidence!"

"…" Confidence? Is this thing edible?

The next morning.

Teacher Zhang counted the number of people and found that there were four fewer people.

"Is this sleeping in?"

He was about to ask other teachers to go to the dormitory to call someone, when he heard a student speak.

"Teacher, they went to eat boiled fish in the dormitory yesterday, and they had a bad stomach and were all paralyzed."

This time, I have to arrange for the teacher to see it.

As a result, after the teacher passed by, he picked up the four people from the bed, and they were all alive and well.

Where is the case of eating a bad stomach.

Sixty students, no less than one, all arranged to go to the university next door to give lectures... Orsay experience.

Teacher Zhang asked suspiciously: "Are you guys deliberately delaying time? Don't be nervous, everyone is just talking casually, and the emphasis is on sharing."

"What's the point of... shame?"

Teacher Zhang smiled and said, "It is said that children's hearts are higher than the sky, why are you all so cowardly?"

While urging everyone to go together, he said, "Don't be afraid, if you can get into the top 60 in the country, you are the best among high school students in the country. Now it's just to get in touch early. Come on, brothers and sisters."

When he said this, everyone thought it was very reasonable.

Yes, before they entered the national training team, they were also among the top students in the provinces, and they were good seedlings on the top of the teachers' hearts.

Why are you so cowardly now?

Someone speaks the truth.

"Teacher, it's because of Yunyan and Brother Wei..."

"That's right, the two of them are so stressful. They make me lose my self-confidence."

"My mother asked me what I did every day in the national training team. I thought that I didn't study today, and I said that I was crushed by the gods every day."

The boy finished this sentence and added, "My mother made me laugh and live."

“…”

Mr. Zhang opened his mouth, and everyone waited for him to speak for comfort.

I only heard him say, "I feel sad for you too."

“???”

Lu Lin couldn't get up.

After a while, he said with righteous indignation: "Mr. Zhang will lose us sooner or later!"

You can wait for more than ten minutes, and when you arrive at Tsinghua Garden, everyone starts to brew their drafts.

After all, no matter how much you are crushed by the gods, you can't lose the face of the national training team.

In such a quiet atmosphere, someone said: "I checked the route last time, followed the map to take the subway, transfer to the bus, and it took half an hour to get to Tsinghua."

However, with Teacher Zhang leading the way, everyone walked in a little more than ten minutes.

Someone next to him finished typing and comforted him, "Just look at the subway and map of Northland, just look at it."

“…”

At nine o'clock in the morning, there were already many people sitting in the conference room of the Department of Mathematics of Tsinghua University.

Professor Ge Song arranged a lecturer to liven up the atmosphere.

"Good morning, classmates, let me introduce you first, and then talk about the process of today's activities."

—In the way of passing flowers by drumming, whoever ends up with the flowers will come to the stage to talk about the math questions or knowledge points they have prepared.

The high school students had embarrassed smiles on their faces.

Damn it, in the face of a group of academic bullies, who wouldn't panic, and had to give a speech...

College students sat around the outer circle, admiring the expressions on the faces of these young children, some were panic, but forced to be calm, and some avoided looking at each other.

Some people encourage each other with others in order to relieve stress.

College students enjoyed it for a long time and found it very interesting.

Young people are really dynamic.

As a result, the next second, they heard the teacher say,

"All students, including undergraduates present, must participate in this event. Whoever wins will give a speech on stage."

All college students present: "???"

Wait, they are not ready!

This time, the high school students in the inner circle looked at the group of college students opposite them and their expressions changed.

Extremely interesting.

Yunyan was different, she was calm from beginning to end.

This time, she did not intend to talk about the Sitafan conjecture she had written, but prepared the question about 'closed circuit calculation' that she had seen in the Proceedings of the American Mathematical Society.

It's all about derivation anyway.

Yunyan chose a simple calculation that can be written in about two blackboards.

After all, the Sitafan conjecture relies too much on the logic of number theory.

She was worried that she could not understand a few words.

It is better to write a closed-loop calculation that is simpler in the derivation process.

Just when Yunyan thought it was about to start, the teacher hadn't finished.

He put the microphone upright, and said excitedly, "This time, we also invited five key members of Y-ITC to participate in the review. The winning students will receive a visit to Y-ITC. Company reward."

High school students may have only one idea of ​​'powerful' for Y-ITC.

But college students know so much, many even make it their own goal!

Therefore, some college students who had retreated spit out bitterness, "Teacher, why didn't you tell us earlier?"

Anyway, I'll give you some time to prepare!

That's Y-ITC! Maybe if you get fancy by the high-level, you can stay and serve!

The teacher was very calm, "You are college students, you have an advantage in age, and you have a home field advantage. The children also learned about it last night, so it's only fair."

“…” Well, fair.

Really, dear teacher.

Yunyan was shocked when she heard Y-ITC. She looked back and saw the man in a white shirt and black pants.

Beautiful eyes and high nose.

She made a silent mouth.

—“哥。”
