――Is that really difficult question? Isn't it just one of the most basic derivative problems?

If you find a derivative of the original function and make the derivative equal to 0, you will know the extreme point? But what did the teacher's sneer mean?

Facing the shiny top of the math teacher's head and the sneer full of grooves, the boy could only stand stunned. Pen % fun % Pavilion www.biquge.info

"Fu Su, I know that this question is too difficult for you, but don't you even have the courage to give it a try?"

"Huh??"

Fu Su was a little confused, this question is still difficult?

"Old ...... Teacher, are you sure you're not kidding? ”

In order to make sure that he had not traveled to another world, Fu Su had to reconfirm the environment he was in.

The large classroom, which can accommodate more than 40 students, is well-lit and has an electric fan whirring overhead. On the walls on both sides are hung the famous sayings of the sages, and above the blackboard in front and back, there are banners with red letters on a blue background.

Everyone's desks, including myself, were stacked with thick books, including textbooks, tutorials, and various volumes.

- That's right, this is the classroom before bedtime.

He looked carefully at the classmates around him,

The girl who looks white and has outstanding looks is the school flower Cheng Xiao, that's right; The handsome glasses man in the front row of her is Zhang Jin, a scholar, and that's right; And there is the guy who is a little fat sitting next to him, who is Xia Cheng, a sworn friend, even more so! And even if he turned to ashes, Fu Su was completely sure to recognize which pile he was. Because even if he turns to ashes, he is the heaviest of them all.

Of course, the bald middle-aged teacher in front of him has no reason to admit his mistake. He is a teacher who teaches mathematics, and the latest Half Moon Bay hairstyle is the most shining one even in space. It is conceivable that if he had a brother or something, he would have been named Xie Di.

All in all, this is indeed the earth where you live!

"Are you kidding? There are still two or three weeks to go before the college entrance examination! Am I kidding you? Teacher Xie's sneer made Fu Su a little embarrassed, so embarrassed that he couldn't bear to look directly at the teacher's face. Seriously, a teacher's face is not naturally suitable for laughing, because whether it is a sneer or a flattering smile, it will make people feel that he is miserable.

"Teacher, may I ask a question?" For the sake of insurance, Fu Su still decided to stay put, and set a set of teacher's words first.

"Ask."

"That...... What is the difficulty of that question? Fu Su was really dizzy, the blackboard was almost seen through by himself, but he really couldn't see what traps were hidden in the question that even junior high school students would do.

"Teacher, don't waste any more time on him, this question is a competition-level, even Zhang Jin Xueba can't do it, do you still expect that low-key little Susu?" I don't know which classmate A said it, but as soon as the words fell, the whole audience laughed.

This was obviously a mockery, but Fu Su didn't have the heart to refute it. He just stood quietly, like a strange being in this world.

"This question is actually a competition level! What the hell are you kidding me! Fu Su said in surprise.

As an ordinary high school student with a positive outlook, I usually don't talk much foul language, but this time the joke is too big! On this question, is it still a competition level? Even at my own level, I have come up with 108 kinds of solutions, how can it be a competition question!

"It's a bit more difficult, and I don't expect you to do it, but it shouldn't be difficult to write a step or two! You must remember that the college entrance examination paper is graded according to the steps, and you can write as many steps as you can. You must know that if you score one point in the college entrance examination, you can advance thousands of places in the rankings! Xie Tian looked serious, but Fu Su looked confused.

Xie Tian saw that Fu Su was moved, so he asked, "Do you want to go up and try it?" Writing one step is one step. ”

Fu Su was puzzled in his heart, he was really just a very ordinary student, and he didn't have a natural vision on the day he was born, so he wasn't a genius or a chosen one; It's not a time-traveler from another world, and no one has crossed over to him, so there's no supernatural spell; I used to be an ordinary elementary school student, then a regular junior high school student, and now a regular high school student. Certainly not reborn, without the ability to change the world. All in all, he is destined to be an ordinary person for the rest of his life. But what's going on now?

The world has been tampered with?

"Look at that guy's expression, the suspicion on his face, it's funny,"

"That's it!"

"You see, he really picked up the chalk and was ready to write! That idiot, I didn't know that Mr. Xie had such a difficult question just to embarrass him."

"Who told him to dare to sleep in Brother Tian's class!"

The classmates were afraid that Fu Su would not hear it, so they deliberately amplified the volume. Cneism is already commonplace for Fu Su. He is a high school student with no characteristics, not introverted, not extroverted, in addition to being kind-hearted and diligent and persistent, it is difficult to find any words of praise to put on him.

Although I was really confused, I was now standing on the podium, and there was no way back.

I don't know if it's right or not, but I wrote three answers anyway. Fu Su just wanted to get back to his seat quickly, which was really uncomfortable to be watched. As soon as he turned around, he froze, and the eyes of the classmates and teachers below widened, and two words were written on their faces-shock!

Especially Zhang Jin's eyes were very wrong when he looked at him, and there was no trace of a smile on his gloomy face, as if he had some deep hatred with him.

Fu Su inadvertently glanced at the school flower Cheng Xiao again, and found that she was staring at herself in a daze. At the moment when their eyes met, Cheng Xiao hurriedly looked away, and because his concern was noticed by the party, Cheng Xiao couldn't help blushing.

And Fu Su is not a particularly confident person, and once thought that he was just too careful. How can a dignified school girl put such an inconspicuous little person in her eyes?

Casually, although Fu Su's appearance has no special characteristics worth talking about, those clear eyes give people an extraordinary feeling.

"He writes it! And it seems to be very powerful. ”

"Did he write it right?"

"Just look at Brother Tian's expression!"

"Incredible!"

"Oh my God, what a genius who hides so deeply!"

In the face of the change in public opinion of his classmates, Fu Su was not so happy, after all, what he was experiencing now had reached an inexplicable point.

-- Is it a play that everyone is putting together? If so, but what is their purpose? This must be God kidding me, I'm really just an ordinary person! Please let me go home and watch TV.

Fu Su was calm on the surface, but in fact he had all kinds of doubts in his heart.

"You...... How do you do it? Xie Tian hurriedly blocked Fu Su on the podium, "Have you ever done this question before?" ”

"Not really." Fu Su scratched his head embarrassedly, "But teacher, is this question really difficult?" ”

"Of course! I adapted it completely to the difficulty of the competition, and at first I was convinced that no one in the class could do it, but I didn't expect you to use three methods to get it right, it's incredible! ”

- No, I need to calm down, it's getting a little weird.

"Teacher, can I get back to my seat?"

"Oh, yes, yes." It can be seen that Xie Tian, who is known as the iron-faced superman, has been shocked to the point of panic.

So, Fu Su returned to his seat. His seat was in the window corner on the right, which was quiet and unremarkable, so no one disturbed him.

"Hey little Susu, how did you kid suddenly become so smart!" The fat man named Xia Cheng turned his head and accosted Fu Su.

"That's right, that is, Fu Xiaosu, did you spend a lot of money to hire a tutor!" A certain rotten girl sitting in the front row of Fu Su also suddenly became interested in him, "Also, that, who is the victim and who is the attacker between you and Xia Cheng?" ”

……

Well, in fact, this corner is not as quiet as expected. Seriously, Fu Su really didn't understand the words of a certain rotten girl.

Outside the window, the trees are shady, and it is peaceful, and the scenery is no different from before.

Originally, Fu Su was about to forget what happened in the last class, but the shocks were always one after another.

"Fu Su, get up and translate this sentence." When Fu Su looked at the blackboard, his heart almost collapsed, and there was only one sentence on the huge blackboard: Who.am.I?

According to the teacher, this is the fourth level of difficulty for English majors!

――I'm sorry, I just want to be quiet, this is Fu Su's only voice at this time......

"Fu Su, which dynasty do you think the great poet Li Bai is?" The Chinese teacher's surname is Han, and Fu Su no longer has the heart to think about what this Teacher Han is called, because he is stumped by this compulsory question in the college entrance examination. Could it be that in addition to Li Bai in the Tang Dynasty, there is another Li Bai in history who is not human?

At the end of the morning, Fu Su finally came to a conclusion: either he is crazy, or the whole world is crazy!
