Don’t Be Aggressive with Me

Cheng Si Qiao's bangs were a little longer, and he covered his eyes slightly on his forehead. Xie Chen helped her put aside and sat upright and separated a little bit from her.

"Xie Chen." Cheng Si Qiao turned over, sat up, covered the quilt on his head, and muttered inside, "You? You are taking advantage of me when I don't pay attention."

"You are my girlfriend." Xie Chen teased her through the quilt, "It's not too much to occupy it once."

"Why not? Excessive."

Before Cheng Si Qiao could react, Xie Chen bent over and lifted the quilt, went in to shorten the distance between the two people again, and then vaguely said to her lips: "Anyway, I have taken it once? It's better to take it again. One time."

The night was quiet, and only the breathing and heartbeat of the opposite party were left in their ears.

It was not until later that Cheng Si Qiao couldn't hold on, so he pushed him away.

Xie Chen straightened her messed up hair just now, and patted her on top of her head. Cheng Si Qiao immediately protected her head and resisted: "Tell you? How many times? Don't you pat me The head, this way you won’t grow taller."

Cheng Si Qiao glanced at the wall clock on the wall, the hour hand was almost pointing to twelve.

"Student Xie Chen." Cheng Si? Qiao's sleepiness has already disappeared a lot, squeezing the flesh on his arm to play, "You can see for yourself what time it is now, don't you want to go back? If it weren't for you, I would have fallen asleep. La."

Xie Chen sat down on her bedside: "Or I won't go back tonight."

"No? Oh." Cheng Si Qiao pushed him away, "I have only one bed. Wouldn't you want to sleep on the sofa all night?"

Xie Chen raised his eyebrows and pointed at the bed, saying meaningfully: "It should be possible to squeeze it down."

"Who wants to huddle with you." Cheng Si? Qiao stretched out his hand and continued to push him, "It's late, go back to bed."

Xie Chen did not answer, and stretched out her hand to open the quilt behind her, Cheng Si? Qiao Yi? Because he really wanted to spend the night with him, he stretched out his hand to stop him, and squatted: "You, what are you going to do? Doesn’t you really want to squeeze into the same bed with me?

"Student Xie Chen, you are acting like a hooligan."

Xie Chen scratched her nose, and there was a little smile in her eyes: "What do you think?"

Xie Chen helped her spread the quilt, stuffed the people into the quilt, and tucked the quilt: "Isn't it to blame me for waking you? I'm here? Wait until you fall asleep and then go back."

Cheng Si Qiao was a little embarrassed to be seen by him? Seeing that he was standing still, as if determined to wait for him, he had to close his eyes and pretend to be asleep.

I don’t know how long it has been, Cheng Si Qiao wanted to secretly see if Xie Chen had gone back, she just wanted to open her eyes, she felt Xie Chen kiss her on her eyelids, her fingertips on her forehead. After rubbing it, it brings a piece of warmth.

"Good night, my girl." She heard Xie Chen say.

In order to ensure the heavy capital rate of students, the affiliated school selects a group of top students every year and formulates special training programs for them so that they can sprint to better schools.

A total of three people in the second class were selected. In addition to Cheng Si Qiao and Xie Chen, Zhou Yangyang was also among the top students.

In the first evening of every day, other students do their homework normally in the class. This group of carefully selected top students must gather in the school’s designated lecture theatre, and a specially arranged teacher will give them to them. Take additional exercises.

On the basis of completing the usual homework, the teacher of the exercises class deliberately searched for them on the Internet to find out the real questions of the independent enrollment of major colleges and universities, and gave them extra homework, saying that it was to improve their ability.

Cheng Si Qiao is not very interested in these policies of independent enrollment, and most of the topics are super-class content. She wanders on the verge of baldness and collapse every day.

One day after the English exercise class was over, Xie Chen was stopped by Lu Qifeng and the others to buy food in the store. Cheng Si Qiao dragged his footsteps back to the class and sat in his seat. After finishing the math contest, the paper was in a daze.

Zhao Tianhao happened to be passing by? She was on the side of her body, and when she saw her with a frown, he couldn't help but joking: "Yo Qiao, what's wrong with your face? He Chen is angry? "

"Come and talk to me, I'll help you analyze it."

"It's not because of this?" Cheng Si Qiao slapped the math paper on the table and exclaimed with a crushing emotion, "Why is there such a perverted math problem in the world?!"

"Are you also having a headache with math problems?" Zhao Tianhao said, "I have heard Yangyang complaining next to me for a while, why is it your turn now?"

Cheng Si Qiao turned his head and complained to Zhou Yangyang: "Yangyang, have you done it yet?"

"Don't mention it." Zhou Yangyang was also miserable over there, "There is no way to think at all."

"It's really annoying." Cheng Si Qiao hammered twice on the table. "That teacher also told me to go to the sky to talk about my own thinking and thinking. What can I say? How did you get beaten by math problems?"

"What question? Let me look at it." Zhao Tianhao was amused by the scene of them? The two? They sang and joined in the fun, "Give it to us? Two college tyrants can't do this?"

"You?" Cheng Si Qiao looked at him questioningly, "Are you sure you can do it?"

"What's this?" Zhao Tianhao tapped her finger on her desk twice, "Although my academic performance is not as good as yours?, but this kind of competition test questions is a kind of thinking that needs to be divergent, in case my inspiration flashes. , Just figured it out."

"Furthermore, I just try it. Can't you do it? There is no loss."

"See it for yourself." Cheng Si Qiao felt that his words made sense, so he pushed the question to him.

Zhao Tianhao took the roll of paper and began to read the questions seriously.

[P is a convex polyhedron, which satisfies the following two properties: (i) each vertex of P belongs to exactly 3 different faces; (ii) for any k≥3, all k-sided polygons in P There are exactly an even number.

An ant starts from the midpoint of a certain edge, crawls along the edge, and walks a closed path L, passes through every point on L exactly once, and finally returns to the starting point L and divides the surface of P into two parts, so that? For any k≥3, the number of k-sided polygons in the two parts is equal.

Prove: The number of times the ant turns left and turns right while crawling is equal. 】

Zhao Tianhao: "..."

The world of Xueba really wasn't something he could set foot in.

"This? The ants are quite naughty." Zhao Tianhao touched his hair awkwardly, "Sister Qiao, Yangyang, take care, I will always support you in spirit?"

Cheng Si Qiao collapsed on the desk in despair.

"What's the matter?" Xie Chen just came back from outside, habitually stuffing the snacks in his hand into Cheng Si Qiao's desk, "What do you guys say?"

"Brother Chen, save Sister Qiao quickly." Zhao Tianhao pointed to Cheng Si Qiao, "She? Is she going to be tortured to death by math problems?"

"what happened?"

"Ming? Tian said that the mathematics competition scroll paper." Cheng Si Qiao tugged at the corner of Xie Chen's clothes, "Have you finished writing?"

"It's finished."

"Boyfriend, please help me." Cheng Si Qiao seemed to have found a life-saving straw, and quietly raised his finger to discuss with him, "I just remembered that she was in the last class? Explain that he asked me to go up and talk about it. ?road."

"Want me to tell you the question." Xie Chen approached her, and asked in her ears with a volume that only two people could hear.

Cheng Si Qiao nodded, and dragged Xie Chen's clothes to death: "You said before. If you have questions I don't know, you can tell me. You are not allowed to say anything."

"I didn't say not to tell you." Xie Chen chuckled, "But? There is a condition."

"Tell a question, give it a kiss."

Cheng Si Qiao: "..."

Zhao Tianhao and the others? How many are still standing around? While watching the excitement, Cheng Si Qiao blushed and slapped him on his shoulder: "There are so many people in the class? How about, Xie Chen, can you restrain yourself."

"I didn't say that I will let you kiss now, save it first, and then cash it when you have a chance."

"And isn't it just a kiss." Xie Chen continued to facelessly, "You have nothing to lose."

"Fine." Cheng Si Qiao thought that maybe after a few days, Xie Chen forgot this? Without much hesitation, he agreed happily.

Xie Chen picked up the corner of his mouth, took out the previous math scroll from his schoolbag and placed it on Cheng Si Qiao's desk, and took the pen in her hand: "Come on, I'll tell you."

"I want to listen." Zhao Tianhao, who didn't know it, dragged Zhou Yangyang to follow them to join in the fun, "Brother Chen, don't stand in the way, this question has already aroused my interest, and it makes me too. have a look."

Xie Chen’s question thinking has always been concise and clear, and Cheng Si Qiao’s comprehension is also relatively high. After scanning his writing process, he has already understood the general direction of the question, plus Xie Chen’s Explaining, I quickly figured out this question.

But Zhou Yangyang was still a little bit ignorant. Cheng Si Qiao sorted out her thoughts according to her own understanding, and Zhou Yangyang quickly figured it out.

Only Zhao Tianhao is still in confusion.

"No." Zhao Tianhao looked at the three people in disbelief? "You all do this? That's the question? Why I still didn't understand."

In order to test his own learning achievements, Zhou Yangyang began to tell Zhao Tianhao, Zhao Tianhao was confused after listening to it, but he still had a lot of doubts. On the other side, Xie Chen's pen in his hand turned twice and suddenly said: "I seem to have a change? simple way."

Cheng Si? Qiao and Zhou Yangyang have joined together? Go and listen, Xie Chen gives them? After finishing speaking, Cheng Si? Qiao couldn't help boasting: "Xie Chen, why are you doing this? How powerful."

"This? Unfair!" Zhao Tianhao wailed on the other side, "I didn't even understand the method just now, Xie Chen, do you have the second method?!"

"Zhao Tianhao, you should give up." Zhou Yangyang passed by? Come and pat his shoulder sympathetically, "Don't force yourself to do anything other than your ability?"

The more Zhao Tianhao thought about it, the more he felt? Hold his breath: "Why! Xie Chen people? Look? No matter if they are handsomer than me, and their brains are smarter than me?! God is partial!"

"More than this?" The person? Xie Chen also passed? Come and pat his shoulder, "You seem to have forgotten one thing."

Zhao Tianhao: "?"

"I still have a girlfriend, but you don't."

Zhao Tianhao: "..."

"Please be your own person?"

At the beginning of the last night of self-study, the lights in the class suddenly went out, and there was only a faint light from the emergency lights in the corridor, and the entire teaching building was plunged into darkness.

"What's the matter?" There were several girls in the class who were afraid of the dark whispering.

Zhao Tianhao got up? Walked to the window and looked outside. The first grade and second grade teaching buildings were also in darkness. He turned around and said to everyone, "It should be a power outage."

"The power went out? Is it okay? Don't go to night study?"

"Okay! Let's go home from school early!"

In the last night of self-study, there was only one director patrolling outside. The management was originally very loose, and after the power outage, the surrounding area was pitch black. It was impossible to see anything. The class suddenly exploded, and some people even cleaned up. Schoolbag, ready to rush out of the classroom at any time.

"Return to your seats and sit down!" The grade director suddenly opened the door of the second class classroom to maintain order. "There is a problem with the school's electrical circuit. It is under rush repair and it will be repaired in a while. Can you? Go downstairs. The campus is very angry, but it is not allowed to sneak out of the school. I have already ruled? The door guard is taking care of it. You? Don't worry about his thoughts."

"The broadcast will notify you when the circuit is repaired? Come back."

Some people in the class were a little discouraged when I heard that they could not leave school early, but Zhao Tianhao had a good mentality and mobilized everyone: "What are you still doing? The director said yes? Go downstairs to breathe, go? Ah! Let's play!"

"Right? Right?! We must? cherish this? rare? time of power outages!" Several other boys echoed, "We will start learning again when the call comes in a while!"

The classmates felt that what they said made sense, and they started walking outside the classroom one after another.

Rare? Yes. Not going to self-study. Cheng Si Qiao was also very excited. He picked up the coat on the stool and got up from the seat, right? Xie Chen said, "Go? Ah, don't you want to go down and go around?"

Without waiting for her to react, Xie Chen raised his hand and grabbed her arm, pulled her forward, and pulled the person into his arms in a strong and domineering manner.
