Excessive exposure

Different classes in City No. [-] Middle School have different dismissal times.

Because of the different grades of the classes, the teacher's teaching methods are also different.Some classmates once joked that although they were all studying in the same grade, they seemed to be from two schools.

There is never a fixed time for class one to leave school, it all depends on the teacher's pleasure, maybe get out of class ends at 18 o'clock, maybe it ends at 22 o'clock.

Classes 21 and 21 end at 22 o'clock in the evening.Classes [-] to [-] end at [-]:[-], and the remaining classes end at [-]:[-].

So Zhou Bingwen and Tang Leyou never met each other after class.

However, after so many things happened today, Zhou Bingwen and Shi Annan had agreed to go back to make up lessons in the evening because the end of get out of class time was the same as that of Shi Annan, so they naturally left together after school.

The teacher of class six dragged the class, and Zhou Bingwen waited directly by the fence outside class six.

When class was finally over, the students of class six came out of the classroom one after another.After a long time of fermentation, the incident at noon spread almost throughout the whole grade. Therefore, seeing Zhou Bingwen standing at the door, anyone who recognized him quietly introduced him to the students next to him.

"Look, that's the one from Class Ten."

"What's the article that week?"

"Yes, it's him. Shi Annan is the one who stood up for him. It's amazing."

It was the first time for Zhou Bingren to be watched in this way, and he lowered his head in embarrassment.Fortunately, Shi Annan walked out quickly, he only held two exercise books in his hands, unlike other students who carried one or carried a bag.

Zhou Bingwen is also carrying a schoolbag, which contains the homework that needs to be handed in tomorrow and the textbooks to be previewed. This thing is much easier than usual.You must know that before Shi Annan stood up for him, in order to protect the textbooks, he had to memorize them every day, which was extremely troublesome.But after today, no one should dare to touch his textbooks again.

Thinking of this, Zhou Bingwen looked at Shi Annan with eyes full of admiration and gratitude.Before Shi Annan could speak, he took the exercise book in his hand and put it in his backpack.

Shi Annan turned his head and stared at the students who were still gossiping, then shut up instantly, and walked away quietly.Then he said to Zhou Bingwen: "Let's go, my driver is waiting downstairs."

Zhou Bingwen was also picked up by the driver. He said, "Uncle Zhang is also waiting for me downstairs."

Shi Annan said: "Tell him to leave work early, and you take my car."

"Eh?" Zhou Bingwen didn't know why, since we all live in the same place, wouldn't it be nice to drive back together.

"It will take 30 minutes to go back on the road, so hurry up."

Zhou Bingwen was ashamed and moved, but Shi Annan thought of him so much, his personality was so good that he didn't know how to repay him.

"Come on, don't delay."

The two walked out of the campus quickly, and luxury cars were parked outside the gate. The hundreds of thousands of BMW that Zhou Bingwen received was very inconspicuous. Of course, if he knew the price of this car, he would still be quite surprised, after all, the building in his hometown The big house I built is only worth 10 yuan, which is considered a luxury in the town.

He trotted to the car window and said to the driver surnamed Zhang who was smoking and waiting in the driver's seat: "Uncle Zhang, I'll go back in a classmate's car, you can leave work early."

The driver seemed a little worried: "Which classmate is it, what time do you go back?"

Zhou Bingwen said: "It's Shi Annan from Shi's family, who lives in the same community as ours. I will go to him to make up lessons at night."

The driver turned his head and looked around, and sure enough, he saw Shi Annan standing not far away, so he was relieved: "Well, I'll watch you get in the car and leave, you should pay attention to safety."

"Well, good. Thank you, Uncle Zhang."

"No thanks."

Zhou Bingwen waved goodbye to the driver, walked up to Shi Annan and said, "I told him, let's go."

Shi Annan led him into the car, which was very spacious, and his long legs still had room to stretch out, so it wouldn't be crowded.Zhou Bingwen sighed in his heart when he got into the car, this car looked quite luxurious at first glance, much more beautiful than the cars of his stepfather and some uncles of the Tang family.

Seeing him looking at the decoration inside the car with admiration, Shi Annan said, "This car has been modified."

Zhou Bingwen didn't understand what modification meant, so he nodded blankly.

Shi Annan didn't intend to talk to him so much, he pointed to his backpack and said, "Take out your book."

Zhou Bingwen quickly unzipped the zipper, took out both the math book and the exercise book, and said, "Actually, I can understand everything in the book. I finished previewing this book during the summer vacation, but the contents in the exercise book I don’t know how to do many problems.” He has always had the habit of previewing the content of the next semester in advance during the winter and summer vacations. This is a very useful way of learning, which makes it very easy for him to listen to the lectures after the semester starts.

But now this method has failed. The knowledge in the textbook and the exercises in the exercise book cannot be compared at all. He even wonders if the school has issued the wrong book.

But the reality told him clearly that he was thinking too much, and the teacher told them mercilessly that the students in the first three classes didn't bother to do such simple exercises.

Shi Annan asked him to circle all the questions he couldn't do.

There is a board table installed in the car, which can be used by pulling it down from the back of the front seat. Zhou Bingwen spread the booklet on it, took out a pen, pressed the pages of the book with one hand, and sketched on it with the other hand.

Shi Annan leaned lazily on the backrest, his eyes drooping slightly, seemingly carelessly, but in fact, his eyes all fell on those hands that stopped and stopped. A sunken arc, blue blood vessels can be seen on the back of the hand, neither thick nor thin, nor convex, in the shape of a straight fork, the upper metacarpal bones make the thin skin transparent, and the four round dimples are really It's a little cute, Shi Annan finally stopped his eyes there.

Zhou Bingwen drew all the questions that he couldn't do in the last two units, sent them to Shi Annan, and said, "That's it, please tell me."

Shi Annan stretched out his hand to pick up the exercise book, the tip of his index finger casually brushed across the back of his hand, and said calmly, "Let me take a look first."

Zhou Bingwen nodded again and again: "Yeah, you look at it first." After that, he behaved and waited beside him.

Shi Annan glanced at him with a smile, and said, "Don't be so reserved, there are drawers under the chair, which contain food, game consoles and magazine comics."

Zhou Bingwen thought that this would be too enjoyable, and Tang Yun's car would have at most a few bottles of mineral water.

Shi Annan saw that he didn't move after hearing this, and didn't try to persuade him. He looked down at the circled topic.After a few rough scans, I analyzed some of the questions he had done for a while, and I roughly understood Zhou Bingwen's question. His foundation is too weak, and it seems that he has never done such a question before.

Seeing him put down the brochure, Zhou Bingwen hurried over and asked, "How is it?"

Shi Annan looked at his face up close, it was fair and clean, not even a mole could be found, and the skin was so delicate, like the porcelain he locked upstairs, one couldn't help but want to reach out and touch it.

"It's very simple. Let me tell you the rules of these questions first."

Zhou Bingwen was pleasantly surprised, and said excitedly: "Okay, okay, this thing is still regular, I never knew, you are really amazing."

Shi Annan pointed to a question and said, "Let's take this question as an example. The known set A={(x,y)|x2+mx－y+2=0}..."

Zhou Bingwen listened carefully, and his thinking became active following Shi Annan's talk.

"First, by Δ=(m-1)2-4≥0..."

"Uh-huh."

"Equation ① has only positive roots, and one of them must be in the interval (0, 1]..."

"That's right, I understand when you say that, so it's like this!" Zhou Bingwen suddenly realized, quickly took out the straw paper and calculated it, brushed it a few times, compared to him tossing about in the classroom for half an hour, and immediately got the answer: "So the value range of m is m≤-1! Is that so?"

"Yep."

Zhou Bingwen's joy was beyond words. He looked at Shi Annan with adoring eyes, and his eyes seemed to be shining like stars embedded in the sky.

Seen by him, Shi Annan had to turn his head away, coughed twice unnaturally, and said, "Then you can solve this problem alone."

"Okay!" Zhou Bingwen picked up the pen excitedly and started to calculate, with a smile on the corner of his mouth, as if he had obtained some treasure, all his mind was devoted to the exercises, not only did he solve the problem that Shi Annan said When he came out, he solved the three problems in one go, and then he put down the pen with unsatisfied feelings.

"Okay, don't bother to do this type of question, you have to help me with my homework later, I will tell you about the next type."

Zhou Bingwen quickly sat upright and listened to his explanation obediently.The more he listened, the more he felt that Shi Annan was more powerful and more effective than the teacher, and suddenly he felt like he hated seeing each other later. If only he had known Shi Annan earlier, he would definitely learn a lot from him.

The two of them were doing exercises like this, and half an hour passed quickly, and the driver had already driven the car back to the gate of the villa.

After getting out of the car, Zhou Bingwen followed him consciously without Shi Annan's words, like a little tail, obedient and obedient, and looked at him with shining eyes.

As soon as Shi Annan stepped into the yard, the nanny hurriedly opened the door and waited. She came over to help him carry things and said, "Want to have supper?"

"Yes, prepare more, my classmate will do homework at home."

The nanny looked at the young boy who was following him in surprise, and didn't dare to ask any more questions, but only said: "Is there anything you want to eat, I'll go prepare it right away."

Shi Annan turned back and asked Zhou Bingwen: "Is there anything you want to eat?"

The Tang family also has a nanny who prepares supper at night. Zhou Bingwen was not used to it when he first arrived, but now he has fully adapted. He said: "Milk and fruit are just fine."

The nanny nodded: "Okay, I'll send it over later."

Shi Annan changed his shoes after entering, and walked directly to the study on the first floor: "Come on, follow me to the study to do homework."

The nanny and the housekeeper looked at each other in the living room, thinking that if they didn't clean it every day, the cobwebs in the study might be enough to weave a quilt. God knows how long Shi Annan hasn't done his homework or opened the door of the study.

The author has something to say: Little Theater:

doing math problems

Shi Annan: So what is the value range of my m?

Zhou Bingwen: Is it -1?

Shi Annan: My value range is you.
