Chapter 229

In front of the city one school, Li Zheng was very upright and talked about it, and he cleaned up the situation from the beginning to the end.

“…… That was the day. Finally, she had a good night with Zhang Xiaoke's mother. "

After that, Li Zheng still remains motionless, at least the surface is not able to see a little flurried.

But Shiyang, next to it, has begun to cool down.

Brother, I know I'm wrong.

But you don't have to do that for yourself!

Shi Yang turned to Lin yuejing and was ready to sneak away.

However, Lin Yue Jing only hummed heartlessly: "it's boring. I went to the exam hall."

Then, he left with a heart beating.

Shi Yang has completely not understood, pulled Li Zheng asked: "this is OK?"

"You have a face to ask?" Li Zheng turned angrily and turned, "no longer guide your EQ class, hit the wall yourself."

"Don't ~ ~" Shi Yang hurriedly chased up and arched Lizheng's arm and asked, "anyway, you two must be friends and girls, right? I'll never read it wrong this time. "

"Sorry, you're wrong again."

"Ah?" "If it's not a boyfriend and a girlfriend, you explain what you do so hard, what's her business?" Mr. Shi said

Li Zheng listened to the words and sang for a moment, and suddenly stared, "yes, what do I explain?"

"Hey, is it not that kind of open boyfriend and girlfriend?" Shi Yang rubbed his hands and asked, "so the girl's tongue..."

"Shut up!" Li Zheng pushed away Shiyang and scolded, "I don't know the tongue of girls. Your tongue is really dangerous!"

"Oh, no, no more." Shi Yang turned out the examination and said, "I have 2 test rooms. What about you?"

“……”

"Ha? It won't be so clever? "

"Stay away from me..."

"Don't you mind. Is it just good for us to go through the exam room and have a beep?"

"No, roll!"

After all, it is Shiyang school. He is a light car, and they push and push together, and soon arrive at the No. 2 examination hall.

The resumption is no more than the preliminary, Li Zheng is serious response, full of 15 minutes in advance into the classroom.

However, from this point of view, everyone in the examination hall is more serious than him, and it has been here for a long time.

This also saves them to find seats. Li Zheng and Shi Yang soon enter the seat, one left and one right, and only one person is separated in the middle.

After putting up stationery and calculator, Lizheng certainly looked to Shiyang.

Shi Yang naturally has already set it up, is warping his single leg, kneading his ankle and smiling at himself.

Looking at the other one in the middle, he was looking down and looking at a blue book.

The words printed on the seal are simple and clear, and they are two words - "Mechanics".

This is the basis of a college physics textbook and a physics competition theory book.

Li Zheng has seen it a long time ago.

It's 10 minutes since the replay. You need to see something about electromagnetism, strengthen the formula and rules. It's ridiculous to see the mechanics textbook.

It's like a gymnast is about to go on the field and hop, and look at the technical action specification from scratch temporarily.

Looking at the man, his hair is a little long, half blocked, and can only be determined from the shirt and sneaker style as a boy.

In short, it looks like learning is very bad.

It's still a long haired monster.

I don't know which school, this hairstyle will not be taught to the director to do.

Li Zheng then swept to the table of the long haired monster, and there was nothing, and he had a pen.

Calculator, physical replay, how can you not use calculator?

Thinking of this, Li Zheng can not help but think of himself in the chemical preliminary.

At that time, I didn't bring the calculator, was reminded by Wu Shuhao, and then she and Eurostar were caught in the middle of the dry.

This scene is similar to that of that time, but the friend who was temporarily holding Buddha feet was caught in the middle.

Li Zheng is thinking about whether to remind the calculator, Shi Yang can not help but start to install.

"Well, I'm very full to think about it." "IChO will be next month," said Shi Yang, patting his thighs, "I will not have time to go even if I get to the final of the event competition."

The people around us couldn't help looking.

This beep is really too stiff, no one was shocked, just want to see which fool is speechless.

But there will be a few goods to know.

"Ah!" A boy was surprised and said, "Jijing really has an IChO player You? "

"Oh." Shi Yang smiled and raised his hand to say hello, "brother knows what to do."

"So you are Cobalt God? "Shiyang?"

"It's just under," said Shi Yang"What's the matter with me?"

"Hey, play around and collect a dragon ball." Shi Yang pursed his mouth, "did not review, so casually into the second round, this material competition intensity is not good."

"Depend on An ox man is a bull man... "

"Kneel down to the cobalt God."

"If you enter the experimental competition, do you still have time to go?"

Learning from the mainland, achievements are respected.

No matter how stupid you are, as long as you learn well enough to get into IChO, you will be praised by all the stars.

Shi Yang had no beep to install in the school. In this environment, he was like a fish in water. He immediately pointed out the rivers and mountains, which indicated that there were many things in IChO's bags.

He blew it. That's not enough.

You have to keep your brother cool.

"Ah Shi Yang raised his hand and pointed to Li Zheng, "Oh, you don't know who he is, do you?"

"Who is it?" People around asked.

"Ha, Li Zheng, God of beauty, have you ever heard of it?"

"I know that Huajing ranks first in China."

"Not bad!" Shi Yang said with a laugh, "the chemical strength of this force is not under me, and the physical strength must be above me. You should be careful in this competition of Yinghu Shuangsha."

"Let's see..." Another boy said in surprise, "I seem to have seen the video of Li Zheng At a party. "

"Brother, you have a good eye." "After all, it's the God of beauty. Qin, chess, calligraphy and painting are all proficient."

"Damn it, our exam room is really good!"

"We can't bear the stimulation of God and less stimulation..."

"Brother Zheng, please do it slowly. Don't scare us."

The atmosphere in the classroom is becoming more and more heated, just like the bullshit in the tavern.

Li Zheng was surrounded by people around him. He just waved his hands and laughed. He had nothing to say.

Although the beep is not correct.

But it was surrounded by people.

Actually, it's quite cool.

I think Li Zheng mixed up for more than half a year, and I'm No. 1. I'm a little bit cool. It's OK.

However, the hairy monster next to me who looked down at mechanics never raised his head.

I didn't even turn the page.

Thinking of Wu Shu's good intentions, Li Zheng coughed and shook his calculator.

"I don't have a calculator, friend?"

The man still lowered his head and ignored him.

Li Zheng waited for more than half a minute and didn't respond. He just shook his head with a laugh.

Forget it, or don't be a good teacher, play your own.

Soon, the three invigilator teachers admitted, the students also received the sound, the hands of the review materials, mobile phones and other things, unified handed in.

Next to the long hair monster but still did not move, the book is still on that page.

Shi Yang couldn't see it, so he took a picture: "brother, don't look, it's too late."

The man did not move.

Wait and see, a invigilator who looks like sun Xiubin also feels that something is wrong. He walks over quickly.

In the middle of the journey, the hairy monster suddenly raised his head, glared and took a breath.

Then, staring at the spot and gasping.

People around were startled.

Invigilator teacher, "low configuration version of sun Xiubin" were scared to stop: "students, need help?"

"No It's ok... " The fury gasped and shook his head.

This voice is tender and weak, in fact, it is not quite like a boy's.

Li Zheng also saw at this time that he was not even a boy. He was too white and delicate, his face was thin, but his eyes were big and watery, and his eyes were full of innocence.

Not only like a girl, but also like a child

As expected, he is a man who does not know the height of heaven and earth.

The opposite Shi Yang also looked for a long time, looked at looked at shyness.

He was not afraid to deal with boys, but he was flustered when he saw such a beautiful and young boy.

At this time, "sun Xiubin" has come to the long hair monster in front of concern asked: "really OK? You don't look very well

"Ah It should be... " Long hair monster eloquence is also OK, quickly wiped his mouth, gradually incoherent, "even if Are you ok Well It should be... "

Li Zheng knows a lot about this kind of shyness and transient aphasia.

"Did you fall asleep and have a nightmare?" Li Zheng asked with a smile.

"Ah Yes, I had a nightmare... " The long haired monster quickly responded, looked at Li Zheng gratefully, then grabbed the book, held the table and said, "I've been sleeping too long Is it time to hand in the books? "

People around him laughed, but there was no malice.

It's amazing that such a big man can enter the second round."Ah..." "Sun Xiubin" helplessly pointed to the cabinet in the back of the classroom, "put all the things irrelevant to the exam there."

"Well, I'm sorry, teacher..."

"Sun Xiubin" said solemnly, "don't be sorry for me. It's not my examination. I hope you can correct your attitude and be worthy of yourself."

“……” The red face of the long haired monster turned around and just caught sight of Li Zheng's smiling face. He also spat out his tongue and laughed. Then he quickly slipped to the back of the classroom.

"Sun Xiubin" had no choice but to shake his head, and then went back to the blackboard and wrote down the notes and time arrangement of the examination one by one on the blackboard.

The long hair monster quickly came back and sat down steadily. After the disaster, he wiped his sweat, blocked his face and whispered to Li Zheng: "thank you."

"Not really." Li Zheng waved his hand and laughed.

Unexpectedly, the hairy monster is still very good to deal with.

It's a little too casual. I can't read the basic textbooks. I don't have a calculator. I doze off.

However, on the contrary, it is also a talented person to be able to enter the second round at will.

Li Zheng then picked up the calculator and shook it: "the amount of calculation in the second round is large, so you should take a calculator with you."

"Ah, is it?"

"Well, it saves a lot of time." Li Zhengchong podium Nuozu mouth, "if you're sorry, I'll raise your hand to say that each examination room should have several spare calculators to provide."

The long haired monster waved his hands, and his face turned red again: "it's OK, it's ok You don't have to... "

"Exams are very important. You are so shy." Li Zheng then leaned over and handed over his calculator. "You use mine. I'll take it."

"No "I don't need to That's enough for me

"Ha?" Li Zheng is neither laughing nor crying, "this is the second round of material competition, mental calculation?"

"It's OK. I'm quick." The hairy monster scratched his head, pushed Li Zheng's hand and said, "thank you."

"Ah." Li Zheng also had to shake his head and take back the calculator, "look at you, should be a senior one? It doesn't matter if we fail this time. We should learn a lesson and prepare well next year. "

Long hair strange smell speech to stay for a moment, and then cover his face a smile, silly nod: "good, good, know."

"Shit..." But Li Zheng was very uncomfortable. "Can't you just end up with" La "

"What's the matter?" he asked

"Forget it Just be happy... "

"That's fine." The fur monster laughed again.

"That's enough..."

"Sun Xiubin" voice suddenly came: "you two haven't talked enough?"

They quickly shut up.

Sun Xiubin then lit the blackboard and said: "last but again, the examination time is from 9:00 to 12:00, with a total score of 320 points. When the bell rings at the end, anyone who writes another word will be punished as violating the rules."

All of them were staring at each other and did not dare to speak.

After all the arrangements are finished, the bell rings and the examination papers are issued.

Li Zheng has been on the battlefield for a long time. After getting the paper, he no longer has the feeling of surging before.

All over the body, there is only one word -

steady.

You don't have to think about grades or something.

If possible, try not to think about Lin Yujing's question answering situation. This is very difficult and can only be done as far as possible.

Just like the usual questions, one by one, just like water.

Li Zheng went to the first question.

It is worthy of the second round, and the difficulty of the first question is up.

In a station wagon, there is a small round table.

There are three rods at the bottom of the small round table as support, like a camera tripod.

And now in the middle of the table, there's a cup of tea.

Ask to make tea as much as possible, and stable, the best should be installed how high.

This is a very common process in life, and it is almost enough.

But if we discuss it from the physical point of view, it will be a long and complicated calculation process.

In the simplest words, it is to make the center of gravity of the water cup as low as possible.

After setting this goal.

This problem has nothing to do with physics.

It turns to analytic geometry and calculus.

One more limit.

Let's combine the equations.

Remove the negative solution.

Well, can't this answer come out if you want to calculate it?

H = m ρ π 2 [{(1 + 4 π 5 · ρ r? HM) ^ 12} - 1]

it's simple and clear, there's no calculation, it's just a hot hand.

The second problem is the little man cart.

It's just that this time it's an agricultural flatbed truck with two wheels, two poles and a big flat plate.

That is, calculus and other things are needed to calculate.

There are also some simple problems of moment, rigid body mechanics and energy conservation.Just a little more attention to a bunch of two-dimensional collisions.

After you've pulled these apart.

What is left in front of me is still a mathematical geometry problem.

It is indeed a calculus competition for middle school students.

After Li Zheng wrote down the answer, he looked at the table next to him.

Long hair monster is staring at the paper in a daze, two eyes Leng lovely.

Well, you are still too young.

Come back home and learn calculus.
