Four gusts of wind

"Let's give you an example, let's say you go to the market and you have to go home, and then you get in the bus, but the bus is not full and you are bored looking out the window. At this time, a car drives by outside the window, your attention is on that car, and you stare at it and have the illusion that the car is parked, and the car you are sitting in is walking, so that car is the reference for you to conclude that you are moving. Another example, I don't know if any of your classmates have ever taken a train, when you take the train, there is a train on the other side and the train you are on side by side, and your eyes stay on that train, so in your eyes, the train is stationary, and the train you are on is also stationary, then that train is the reference for you to judge that you are stationary. So ......

".

Listening to the lecture, he unconsciously moved his eyes to the window again, the sky was very clear, the wind was very warm, some of the leaves outside had begun to turn yellow, and the grass had hammered down its head, and before he knew it, it was autumn again.

Like,I remember that there are some pictures in the game that the scenery outside is very beautiful.,He's wondering.,Is there such a game.,Those beautiful scenery can be walked over directly.,It's no longer just for seeing.。 It would be nice to have a game like the real world, where everyone is in the same picture, they can build a house at will, they can cut down trees, dig wild vegetables, pick wild fruits, they can go anywhere they can see, and there are no more high walls or Gobi cliffs to gamble on.

Thinking about it, he slowly entered another world, where there are no seasonal changes, the grass and trees are evergreen, the flowers are full of mountains, people will not feel hungry and cold there, they don't need to farm, they don't have to be busy, they can have fun every day, they can eat all the delicious things they want, they don't need to eat if they don't want to eat, and they don't have to accept the influence of their stomachs.

Of course, there must be an Internet café, right by the clear river, next to the computer and a few fragrant flower pots, play in the river during the day, and go back to the Internet café to play games at night until you get bored.

I also have to bring the big white with me, raise a few rabbits, and watch them quietly every day when I am idle and bored, and when I have a new idea, when I will go out to play.

There is also Xiao Ran, the first thing he does when he wakes up every day is to go to Xiao Ran, take her to the river to catch fish, build stones on the river bank to grill fish together, and then carry a recliner and lie on the river bank to watch the sun.

Small Dye ...... Small dye ......

Thinking of Xiao Ran, the scene of that day gradually came to mind.

If only I could run faster that day!

"So the two states of existence of objects, motion and relative rest, do you understand it?".

"Got it!".

He came back to his senses, looked at Yang Yong, who was smiling on the stage, and then looked at the people in the audience who were holding their heads high to explain, and shouted blankly to understand, then looked down at his book, and then looked at the old horse on the side.

"What page did you get to?".

"How do I know. "

Seeing that the old horse shook his head, he turned around and asked while Yang Yong was not paying attention.

"What page did you get to?".

: "Thirty-three pages. "

"Oh. "

After getting the answer, he turned around and quickly turned to the page that Long Yufen said, and Lao Ma also followed him when he saw this, and when the book turned to page thirty-three, the two looked up at each other, and then naturally one looked out the window in a daze, and the other looked at the stage in a daze.

What did you just think of?

He remembered that he had just reached the realm of self-forgetfulness, and in such a realm, a class would soon pass, but where had he just arrived?

After thinking about it for a long time, he still couldn't think of what he had just thought, so he could only create a new fantasy.

I don't know how long later, the bell rang for the end of class, Yang Yong packed up his textbooks and went out, and the bell rang again, an almost bald head, with only a few strands of white hair around his head, and his beard was also covered with white spots, and a somewhat burly old man slowly walked in with a math textbook.

As Yang Yong said, the math teacher was the oldest teacher in the school, his expression was always serious, and he spoke in a loud but clear voice, which was clearer than Yang Yong's voice, which looked to be about 30 years old.

"Where did we go in the last lesson?".

: "Corner corners, corner edges, corner edges, edge edges." "

"There are no edges and corners. "

The math teacher put the textbook on the lectern and said with a smile.

"I told you in the last class, edge by corner, corner by corner, broken feet, broken feet, how to count if the feet are broken, there were often students in the last class who made this mistake, I mentioned this to you just don't want you to make it, why do people still tell me about the corners." Remember, proving whether a triangle is a right triangle or an acute triangle can only be proved with corners, corners, corners, corners, corners, edges, edges, corners, corners, edges, corners,

"Got it!".

"Wu Rubing, do you understand now?"

"Understood, understood. "

The old hippie smiled in response.

"Understood, I don't want you to give me this corner for the next exam, if you really write I'll have to knock you on the head." So, let's continue with what we talked about in the previous lesson, and say that there is a triangle, and one of the angles A is known to be 30 degrees, and the sides B and C are 3 centimeters, and the other is 2 centimeters ......".

Math class, for people who don't like to study, seems to be the most boring class ever, and he continues to look out the window and think nonsense.

Seeing a leaf falling, in his eyes, it was as if he saw a boat moving in the air, and on the boat there was a poet often seen in books pointing to the mountains and seas while waving a fan and reciting those verses that he had listened to countless times.

He watched quietly, listened, and quietly entered it, drinking and writing poetry with those poets, although in reality he did not drink.

"So, what law can we use in this piece, Long Shaoxing, you get up and answer." "

"Huh?".

He got up suddenly, and then looked around in confusion, and at this moment, almost the whole class was staring at him, and the old horse lowered his head and told him with his eyes that he didn't know.

"The Law...... ......" is used

: "The Pythagorean Law. "

When he was helpless, an extremely gentle and small voice came from behind him, and he hurriedly replied after hearing it.

"It's the Pythagorean law. "

"Okay, then tell us about the formula of the Pythagorean law." "

: "Formula...... Formula ......".

: "A squared plus ......".

Long Yufen behind him continued to whisper, but was interrupted by the math teacher before he could finish speaking.

"Let him come by himself, you can help him now, you can help him during the exam, can you still help him in the high school entrance examination?"

He looked around blankly, and then looked behind him, Long Yufen, Yang Qin and Lao Ma all lowered their heads, and the rest of the people all looked at him, facing so many eyes, he felt that his cheeks were slowly becoming hot, as if they were baked by the remaining sunlight.

:“a...... a......"

"Alright, sit down." "

The math teacher sighed when he couldn't answer anything, and then looked at the old horse.

"Stone tree root, you get up and answer. "

As soon as this sentence came out, everyone burst into laughter, and at this moment, their focus was no longer on the answer to the question, but on the name of the old horse.

"Teacher, it's a stone root tree. "

"The stone roots are the same, and the stone roots are a little smoother." So, Shi Genshu, get up and answer what the Pythagorean law is and what its formula is. "

The old horse simply stood up and said no, to which the math teacher could only shake his head and sigh and motioned for him to sit down.

"Tell me about the two of you, one looks out the window in class and wants to become a bird, and the other straightens his neck to look at the podium, but his eyes have long drifted to nowhere. It's already the second year of junior high school, so let's have a snack, and when you reach the third year of junior high school, it will be too late to work hard. Alas, Wu Rubing, get up and talk about it. "

: "The Pythagorean law states that the sum of the squares of two right-angled sides is equal to the square of the third side, and its formula is that the square of a plus the square of b equals the square of c. "

"Very well, sit down." Let's move on to this problem, then using the Pythagorean law, we can find that this triangle is a right triangle, so the length of the side c is 5, and c is parallel to d, and e is parallel to f, so in the same way, the length of the other side is also 5, and the figure is a rectangle. Do you two understand?".

"Understood. "

He didn't know what the teacher was talking about, but after hearing the teacher ask, he still pretended to be confident and nodded, and the same was true for the old horse.

Then, the time of this class was extremely long, he quickly took out the lunch box from the table and started running, ran to the door and remembered something, hurriedly nodded and Lao Ma grabbed one of Long Yufen's hands and dragged her to continue running, and Long Yufen's lunch box was also transferred to Lao Runa.

Ran to the cafeteria, there were still only a few people inside, they hurried to fetch food and then walked to the old place with rice bowls.

This season, squatting in the open space in the back mountain, the sun is no longer hot, the wind is even slightly cold, and before he knows it, the foursome is back in the five, he thought, if only Alin hadn't transferred to another school.

"Wu Rubing, were you really the second in the school next door before?"

"He's bragging, don't believe him, he said in our dormitory before that he was only the eighth in the school, but this kid didn't have a word of truth in his mouth, and it remains to be seen whether he is the eighth in the school." "

Without waiting for Lao Ru to answer, Lao Ma took the lead in answering.

After listening, Long Yufen nodded suspiciously.

"Oh. So how many are you in the whole school?".

"Actually, I couldn't get into the top ten at all, I just bragged to Yang Yong and them at the time, otherwise how could I come to this class." "

"Okay. "

"That's it, Yufen, don't believe him. This guy, on the first day I came here, I looked at him with a thief's eyebrows, and he looked unreliable. "

"Alas, what's not reliable, I'm a thief who is reliable." "

"You're reliable. "

Saying that, Yang Qin turned his face away and stopped arguing with Lao Ru, and Lao Ru moved his gaze to him who was eating quietly.

"Fei, do you think I'm quite reliable?" "

"Are you embarrassed to ask Brother Fei? Brother Fei told me last time that he called you from the time he went out, and you said that you had already gotten up, but when he arrived at your house, you would get up slowly." "

"Isn't it that I have to wait for him to walk a while when I get up early and get up late, it's boring to wait for so long, what's wrong with sleeping too much?

"I don't speak, you can do it yourself." "

He shook his head and continued to eat.

"Wu Rubing, you and Long Shaoxing came to school together?"

"Yes, our two villages are close to each other, so we both came together. "

After listening, Long Yufen nodded.

"Oh. You're so close, you should be in the same elementary school, right?".

"yes. "

"Then why did you and Long Shaoxing look like they didn't know each other before?".

"He's in the same class as my brother. "

As he spoke, Long Yufen immediately looked incredulous.

"You're two years older than us, huh?"

"Hmm. Previously there were two levels left because of some things. "

After speaking, Lao Ru scratched his head embarrassedly.

"Otherwise, you really think that I can answer those questions casually, but I have studied it many times and remember it relatively firmly in my head." "
