It's good to tease the teacher

, is not derivable, so it does not meet L’Hopital’s condition 1, for this reason: the correct way: shill n as x, then use L’Hopital, and finally change to n.That's right. After Zhang Chen finished speaking, he sat down directly, and Wang Xi didn't say anything.

Wang Xi nodded, "I thought everyone knew this, so I ignored it, but I'm really to blame. Zhang Chen said it very clearly just now, did everyone understand?"

"I heard it." Wang Xi didn't care about the sparse voice and continued to lecture.

In this class, Zhang Chen molested the teacher twice. This is how he defined the students in private, but it still made the students very excited.

Zhang Chen's behavior silently promoted Wang Xi's class, and many strange faces appeared in the subsequent class for no reason.

After a month like this, Wang Xi's classes were full every day.

"Student Zhang Chen, come up and write these questions." Wang Xi's lectures have changed from writing the questions by herself to now appointing Zhang Chen to write.

Zhang Chen couldn't tell whether she was happy or unhappy, and the revenge seemed to have succeeded, because this change obviously showed that she made Wang Xi unhappy.But in the future, I can no longer flirt with Wang Xi, and I can no longer see Wang Xi's calm expression on his face when he is clearly angry. Whenever Wang Xi shows that expression, Zhang Chen can recall it for a long time.

Zhang Chen has already learned his lesson, there is no rush to eat or something, the worst thing is to order takeaway.Holding the book, before Wang Xi left, he ran forward.Anyway, I want to make Wang Xi upset so I can't let her eat so early, "Teacher, I don't understand much here, can you talk to me seriously?"

Chapter 4

Zhang Chen quickly packed up the things on hand, and caught up with Wang Xi who had left one step earlier. As for the roommate, they watched Zhang Chen leave.

During this month, Zhang Chen was busy with various things without gossiping.But the roommate is still a gossip, and heard all kinds of rumors, well, it can be said that rumors are flying all over the sky, and each one is more exciting than the other.

For example, one is that many people have come to their advanced mathematics class recently, to what extent?They didn't dare to be late anymore, even though Zhang Chen took the seat, without Zhang Chen, they would almost have to stand and listen to the class.They privately gossiped about three reasons why so many people came: because of Wang Xi and Zhang Chen's appearance, because of Wang Xi and Zhang Chen's "competition", and because of Wang Xi's lectures.During their discussion, they even looked up at the person concerned, and they continued the discussion as if the person concerned was nothing wrong.As everyone knows, although the person concerned is watching a documentary, can he still have ears?It's impossible to block it that much, but Zhang Chen naturally won't let this rumor go.

Second, I don't know where this rumor came from, but it probably came from some rotten girl.It is said that Zhang Chen and Wang Xi fell in love with each other and killed a bunch of singles.There are even some people discussing which of them attack and which suffers, this brain hole is big enough.Zhang Chen also heard it by accident, but she just shook her head lightly, she still doesn't understand the world of rotten girls.

Zhang Chen caught up with Wang Xi and stood side by side with him, "Teacher, do you live in the school or do you have a house here?"

Wang Xi was a little taller than Zhang Chen, and wondered if this student wasn't too close to the teacher, but the one in front of him was really approaching actively, and he was not an instructor or their professional teacher.Getting close to her won't bring you any benefits, Wang Xi looked at Zhang Chen suspiciously, "Why are you asking this?"

"It's not because I'm afraid that there will be problems at that time, isn't it? If you know that the teacher lives on campus, it will be more convenient to find the teacher. Besides, even if I don't have so many problems, other students will. I can’t tell you clearly.” Zhang Chen’s words are well-founded.

Wang Xi didn't think there was anything wrong, "I do live on campus, but the teacher's dormitory is quite far from your student dormitory."

"No wonder, that time in the cafeteria, I saw a back that looked like you, teacher. I thought I was blinded and mistook the wrong person. I almost went to the optical shop to get glasses." Zhang Chen said with a smile.

"However, you may be mistaken. I seldom eat in the student canteen. Our school has a staff canteen, and the staff canteen and teachers' dormitory are relatively close, so it's more convenient there." Wang Xi paid attention to the steps under his feet. It was full of people, and only the heads of people could be seen.

"Then teacher, can you take me to see where the teacher's dormitory is. It happens that I don't have classes in the afternoon, so it's convenient to go directly to the teacher next time." Zhang Chen said in a very serious tone.

At this time, we have already finished walking the steps. The teachers' dormitory and the student's dormitory are in two directions. Wang Xi was going to tell Zhang Chen that the directions are different and I will go back first.But he didn't want Zhang Chen to say this, Wang Xi's face flashed with astonishment, he turned his head to look at Zhang Chen's face and said, "But classmate, I'm sorry, I have other things to do this afternoon."

Zhang Chen showed disappointment on his face, "But teacher, don't you want to go back to the dormitory too? Just take me along the way." Zhang Chen blinked, and his voice could not help but be a little coquettish.

"Alright then." Wang Xi felt regretful after finishing speaking, he really owed it.But I agreed for some reason, maybe seeing the girl who was holding her in front of me rarely showed the posture of a little girl, I thought it was cute and funny.It is impossible to regret what was said and the water that was spilled, and she is still a teacher.

Zhang Chen was overjoyed, she didn't expect it to be so easy, and she prepared a lot of excuses, "Then teacher, let's go." Zhang Chen was overjoyed, and even put his arms on Wang Xi's, Wang Xi didn't show it. Traces broke away.Zhang Chen touched his nose in embarrassment. He usually doesn't like to be close, so why was he overly excited just now.

Along the way, Zhang Chen felt a little embarrassed, so he didn't speak.On the other hand, Wang Xi acted as if nothing had happened, and took the initiative to speak first, "I'm going out later, you can walk to the dormitory with me and go back."

"Well, yes, teacher. Teacher, can I add you on WeChat?" Zhang Chen felt that he was really making progress.

"Don't you have my phone? That's my WeChat."

"But I always feel that it's not very good, and I'm not sure if it's the teacher. Besides, wouldn't it be embarrassing if the teacher rejected me directly? So I think it's better to take the initiative to say hello to the teacher. "In fact, Zhang Chen searched Wang Xi's phone number many times. The profile picture is also Wang Xi himself, with a bright smile. Zhang Chen really wants to call, but he is afraid of being rejected. It would be embarrassing for the other party to say that he doesn't know him.

"Well, I won't refuse. Anyway, you are quite famous, so I wouldn't be ignorant." Wang Xi's voice carried a hint of ridicule, and Wang Xi looked up at the front, "Okay, I'm here, you Let's go back."

"Teacher, don't you eat?"

"I have an appointment for dinner, so you go back to eat." Wang Xi looked at his watch.

Zhang Chen looked at the other party's actions, and felt sorry for the delay, so he could only say, "Goodbye, teacher."

"Good." Wang Xi turned around and left.

Zhang Chen looked at the back of Leaving, and found it disgusting no matter how you looked at it.So he quickly turned around and walked on the way back.

Really, it’s better for students to molest the teacher. Recently, Wang Xi turned back a game, which made Zhang Chen very depressed. After all, she was having a good time, and then she felt like being thrown a basin of cold water all of a sudden.

Zhang Chen seemed to think of something suddenly, the corners of his mouth raised, and he smiled in relief.Now that I know your address, I'm afraid I won't be able to find you.As for the method, isn't there a saying called "Ask Google if you are undecided about foreign affairs, ask Baidu if you are undecided about internal affairs, and ask Tianya if you are undecided about intercourse."

There was a vibration in his pocket, Zhang Chen took out his phone, glanced at Rowling, "What's wrong? What's the matter?"

"There is class in the afternoon, don't you know? Where have you been? It's almost time." Zhang Chen could even imagine that the other party's expression was anxious and speechless.

"It's okay. It's okay if you don't listen to the class in the afternoon. If you call the roll call, you can use any excuse to excuse it." Zhang Chen said indifferently, the old man liked her a lot in that class, so it shouldn't happen, and the old man rarely roll call.Although the old man is actually less than 50 years old.

There was a silent sigh over the microphone, and then hung up.

Chapter 5

"Teacher, teacher."

Wang Xi picked up the phone and found that Zhang Chen had sent a message. In fact, Wang Xi wanted to ignore it a little bit. Are the children all busy now?Looking at the child's appearance, it doesn't look like he is very idle, why is he doing nothing but boring things.

While Wang Xi was still hesitating, the other party sent another message: Teacher, are you there?

Wang Xi was a little helpless, and started to reply with a wave of her finger, because she was afraid that if she didn't reply, Zhang Chen would be endless, or her "fragile" glass heart would be hurt from then on.

"What's the matter?" Zhang Chen hesitated for a long time before sending the WeChat message. If Wang Xi didn't reply, she really didn't know if she would have the face to continue sending it.Seeing these three words, although it looks very cold, it is still quite cute.

"Teacher, you have a new hairstyle. When I was in class, I heard many students discussing your new hairstyle." Zhang Chen typed these words a little excitedly.

"So that's why you listen to the class so seriously?" Wang Xi grasped the word "class", although she was still very relieved about Zhang Chen's classwork.

"Teacher, why don't you ask me if you think the new hairstyle looks good, but it doesn't matter, I still want to tell you, it's very beautiful. And there is no contradiction between listening to the class and listening to this, and there is no delay." Zhang Chen quibbled.

Seeing this, Wang Xi couldn't help but smile, as a teacher, is this being molested?The friend on the opposite side saw Wang Xi looking at the phone and suddenly smiled, and smiled too.
