My Identity As A Schoolmaster Has Been Exposed

Chapter 198 The final question that stumped the first grade!

When Xu Cong saw her clumsy performance and bloody plot, he interrupted her directly and said, “How boring I am! What and what is this! We can’t be more pragmatic and seek truth from facts?”

He waved his hand at Lin Mengjiao again, he didn’t intend to listen to Lin Mengjiao’s gossip news.

When she got down and yawned, Lin Mengjiao thought he would sleep, but she took out her mobile phone.

“Uh…it seems to be out of power…”

Looking at Lin Mengjiao, Lin Mengjiao shrank her neck and said, “The head teacher just took away a mobile phone. I didn’t dare to take it. I put it in the locker of the dormitory.”

Xu Cong is completely boring.

“Hey…” Xu Cong felt a little uncomfortable looking at the phone’s 5% dots.

“Ling Ling Ling…” The class bell rang.

Xu Cong asked boredly: “What class is this class?”

Lin Mengjiao answered casually: “Chinese class!”

When Xu Cong heard that it was a Chinese class, his eyes suddenly brightened. As soon as Su Rui entered the office, Xu Cong looked at Su Rui.

With a glance, Su Rui, who was about to go to class, walked up to Xu Cong.

“What’s the matter?” Su Rui asked.

Xu Cong handed her mobile phone and electric pump to Su Rui, and Su Rui turned black in an instant.

“I…! You fellow!”

The whole class can see it!

Xu Cong gave the mobile phone and charger to their Chinese teacher, and the Chinese teacher was still in his hand!

The students had insufficient brain circuits, and each of them became puzzled and whispered to talk.

“Do you take the initiative to hand in your phone?”

“Xu Cong has a mobile phone. It’s normal, shouldn’t I hand it over?”

“How is this going?”

How could they think that Xu Cong’s mobile phone is out of power and let the teacher charge it!

Su Rui sighed, and under the attention of the whole class, took the mobile phone and charger back to the office.

The teacher in the language group of the office was stunned when she saw her come back, and asked: “Mr. Su, aren’t you in class? Why are you back again?”

Su Rui said without conscience: “The phone is dead, recharge it.”

“Ahem!”

She was embarrassed at this time, put it on the power strip and left immediately.

The teachers felt very strange looking at her turmoil. At the same time, they took another look at the charging phone, and their doubts deepened.

“This doesn’t seem to be Teacher Yao’s phone? Has it been replaced with a new phone?”

Back to the class, Su Rui was empty-handed. The classmates were also dumbfounded. What about the “???” mobile phone?

Why is it gone? Was taken away?

Being confused, Su Rui started today’s lecture, “Everyone will…”

The class started, and everyone’s thoughts were pulled back, and everyone temporarily forgot about it.

But after class, Su Rui returned after leaving, holding the mobile phone and charger in his hand, suddenly a classmate realized that Xu Cong’s mobile phone was dead, and he used it to charge Su Rui!

Now that get out of class is over, she took her phone back and gave it back to Xu Cong.

Xu Cong took the phone and said gratefully, “Thank you, teacher.”

Su Rui left without saying anything, but the whole class is about to boil!

“!!!”

“My God! My God! My God!”

“I’m going! I’ll go and go!”

“It’s all OK?”

“Any school bully is weak!”

“Some of the tyrants who have been brushed up online are so weak!”

“I have seen Xueba’s mobile phone running out of power, and helping to charge it when it comes? I still use it to charge it during class!”

“My God! This is too bad!”

“hiss!”

…

Looking at Xu Cong now, they seemed to have seen a ghost. Xu Cong didn’t care about the eyes focused on him, and he swiped his phone calmly.

This is not the first time, what’s all the fuss about.

.…Forehead!

and many more!

It seems to be the first time they have seen each other.

The students turned their heads to look at Tang Yongxue and asked, “Hey! Did Xu Cong used to be like this when he was in Class 3?”

Tang Yongxue also took a cold breath. How did he know that although he knew Xu Cong was picked up by Su Rui’s car, but charging this kind of thing… Wait, compared with the private car, this is obviously the pediatrics.

Tang Yongxue didn’t say the more exciting things, and bit his scalp and said to them: “Don’t make a fuss!”

Everyone just stared out, and said excitedly: “Isn’t this weird? You still let us not make a fuss!”

Tang Yongxue sighed, and reluctantly said part of Xu Cong’s pretence than history: “It’s rare and weird! In Class 3, Mr. Su also took a special car to pick you up!”

Fuck!!!

The teacher’s private car?

What a luxury it is for students who live on campus. Every time on vacation, students who live on campus carry their bags and go to squeeze the bus!

But Xu Cong actually has a special car, and it’s the teacher’s car!!!

This time, they refreshed their understanding of Xu Cong.

“Full score, do you really have so many privileges in school?”

“He is not just full score! There is also one, oh no, there are two incredible full score essays!”

“Xu Cong is about to become the school’s golden sign!”

“Full score is part, composition is also part, and Xu Cong going to the TV station to participate in the show is also part!”

“Yeah!”

Come to think of it, this student who only sleeps and plays with his mobile phone in the class has far exceeded the category of the student, and he has blossomed in different fields!

“I can also paint! Playing ball is simply omnipotent!” Tang Yongxue muttered, some classmates were completely dumbfounded.

“Is he good at sports?” a classmate asked tentatively.

Tang Yongxue nodded.

Everyone immediately had a black line, with smiles on their faces that were uglier than crying, and their cognition was refreshed every day—every day! I was shocked by Xu Cong every day!

Lin Mengjiao watched everyone staring at Xu Cong, and Xu Cong, after getting the phone, put on the headphones and started to play the show.

Time can’t be wasted!

When returning to the dormitory at night, Xu Cong found the dormitory and said warmly, “Uncle!”

The big uncle followed the sophomore classmates to the new dormitory.

Su Guan watched him come to find himself, and asked very caringly, “What’s wrong?”

Xu Cong said helplessly: “The phone is out of power, let you charge it for a while!”

When the dormitory heard that it was a trivial matter of charging, he patted his chest and promised him: “Okay! I will send it to you before going to bed.”

It’s rare that Xu Cong didn’t hold his mobile phone today, but he gave Yang Kaixuan a chance.

“Can Xu Cong discuss a math problem with you?” he said to Xu Cong.

Xu Cong thought for a while, anyway, he was idle, so he played with him, so he asked aloud, “What question?”

“The last math question in the college entrance examination.”

Xu Cong froze for a moment, but soon returned to calm.

Yang Kaixuan was once the number one in the whole year, and it was reasonable to consider these issues.

It is very difficult to answer the last mathematics question for the college entrance examination. It is to make it difficult for top students like Yang Kaixuan to go to a key university or a better university!

Generally, the difficulty of the last math question in the college entrance examination is uncertainty. Even if you have practiced a large number of questions and memorized all the formulas, there is still a 99% probability that you will not get a full score.

As for the items that can be scored, top students can get it, and some ordinary students with average grades can also get it.

The gap can’t be opened!

Xu Cong smiled and asked directly: “Did you not even understand the title and can only write a solution, or did you use the ideas in advanced mathematics?”

These two are the two main categories of the final mathematics questions in the college entrance examination. Xu Cong knows these types of questions very well.

Yang Kaixuan sighed and said helplessly: “I probably understand what you mean, especially for advanced mathematics. It seems obvious that it is not difficult, but when it is done, there is a complete problem! There is a big deal!”

He was a little burnt at the moment, “I think the math finale that is good for the test is deliberately set to be so difficult.”

Xu Cong smiled and said to him, “This is the way it is, don’t you know?”

Yang Kaixuan was speechless and didn’t know what to say for a while.

Xu Cong didn’t say anything to him, and immediately asked for the title: “Show me the title.”

He also wanted to see what the problem was, which made the former No. 1 of the whole year stumped!

topic:

Known function f(x)=(1/√x+1)+(1/√1+a)+√(ax/(ax+8))

(1) When a=8, find the monotonic interval of f(x);

(2) For any positive number a, prove that: 1≤f(x)≤2.

Xu Cong knows this question. It was an average of 0.31 in a province that year, and none of the 300,000 candidates in the province did it right.

And there is only one person with the highest score of 9 points, and two for 8 points. Later, after the examinees read the answers, they didn’t even have the idea of ​​copying!

It’s so difficult!

too complicated!
