Reborn Xueba, you don't really think that studying is difficult, do you?

How difficult is this math test?
Just look at the few real questions below.

“1：设a=0.1e^0.1，b=1/9，c=-ln0.9，则下边大小正确的是……”

[A: a<b<c. 】【B: c<b<a. 】

[C: c<a<b. 】【D: a<c<b. 】

"2: x+y+2=0, intersect the x-axis and y-axis at points A and B respectively, and point P is on the circle (x-2)^2+y^2=2, then the area of ​​△ABP The value range is..."

[A: [2,6]. 】【B: [4,8]. 】

【C：√2，3√2]。】【D：2√2，3√2]。】

"3 It is known that the center of the hyperbola is at the origin, and a focus is F (√7, 0), and the straight line y=x-1 intersects it at two points M and N, and the abscissa of the midpoint of MN is -2/3, Then the hyperbolic equation is..."

【A：x^2/3-y^2/4=1。】

【B：x^2/4-y^2/3=1。】

【C：x^2/5-y^2/2=1。】

【D：x^2/2-y^2/5=1。】

……

Look, is it hard or not?
For example, for the first question, if you bet ten packs of spicy strips, at least five of the ten candidates will not be able to do it.

If you don't believe me, everyone can do it.

Although it is a size comparison question, it seems okay at first glance, but it is really only at first glance!

If you do it carefully, the amount of calculation is not ordinary, and you need to use extreme zooming, which is comparable to solving a problem.

Of course, there are simpler ones, such as using the Taylor formula, but this formula does not seem to be learned in high school.

So you say the question is beyond the outline?

Sorry, it's really out of line.

But if you want to say that you don't go beyond the outline, the amount of calculations can be compared to the kind that solves the problem, aren't you deliberately making things difficult for others?
Of course, with Zhou Buyi's third grade in his grade and his ability as a god of learning, he can definitely solve this problem, but it may take a little longer.

But the multiple-choice questions take a long time, and then there will be insufficient time later on, this is something Zhou Buyi can't tolerate.

Let's look at the second question again.

Find the value range of the area of ​​the triangle.

It is also not difficult at first glance, but after careful calculation, it is estimated that it can make people cry.

If there is no convenient method, the amount of calculation is only higher than that of the first method.

As for the curve equation of the third question...

Nima!

Follow the previous exam pattern.

This kind of problem of finding the curve equation is the sixth, seventh or eighth question of the single choice!

Even if it is not the main axis of the stage, but as the penultimate finale, it is more than enough.

After all, the question involving the curve equation is more complicated than the second one, and the amount of calculation is greater.

But this time, the exam was placed in the third multiple-choice question. Isn't this supposed to crush the candidates?

Even a scholar like Zhou Buyi would tremble a little when he saw these questions, let alone other ordinary candidates.

Moreover, this is only three questions.

Everyone knows that math tests, no matter whether it is to choose, fill in the blanks, or answer, it has always been more and more difficult as the test progresses.

This is the case with two or three.

What about four, five, six, seven, eight, and multiple choice questions?

Thinking about it, Zhou Buyi lost his mind.

Of course, to say that the difficulty of these questions is really comparable to a competition is not true, after all, the solutions are completely different from each other.

But the overall difficulty is really not low.

I want to finish this test within two hours, including Zhou Buyi, I am afraid that few people can do it.

Even the invigilator on the stage frowned when he saw this paper.

"What the hell are you doing here?"

"Isn't the person who produced the test group crazy?"

"It's not enough to choose one, two, and three questions as the last major task, but it is more than enough as the finale. It is difficult for ordinary candidates to do it in seven or eight minutes."

"But in the end, the questions like this exam came at once, and they didn't say anything, so they just put it at the beginning?"

"Don't talk about these ordinary students, even if they are replaced by professional teachers like us, they will be crazy!"

"Needless to say, this is definitely the paper written by Ge Tianxing and Mr. Ge himself. Other than him, no one else has this ability, and they dare not have this ability. After all, they are afraid of being scolded..."

Sun Xingyi, the invigilator of class two, shook his head for a while.

After all, he is also a senior math teacher in the school, the kind who has led several classes, and can tell the difficulty of this paper at a glance, which is beyond all previous exams.

Even the mathematics papers of the college entrance examination in recent years have to be hanged by the mathematics paper of the joint entrance examination this time.

Perhaps, it can directly catch up with the college entrance examination paper in 03.

But that is the most difficult paper for the college entrance examination!
And now it's just a small ten-school joint exam in Lincheng, and it's so difficult.

Almost immediately.

He began to mourn for the candidates in the class.

There is no doubt that this math test will inevitably make countless candidates suffer greatly, and even feel collapsed.

Don't talk about high scores, I'm afraid not many can get 100.

After all, even as a math teacher, he couldn't get a high score in just two hours.

But in the next second, when he came to Lin Bei's side as the invigilator went back and forth, his pupils suddenly opened.

"???"

"??????"

"This, what happened here? This, how is this possible? Is it my eyesight, or am I dreaming???"

"How could this person finish the multiple choice questions so quickly in such a short time?"

"Eight single-choice, four multiple-choice, and one twelve-choice. Normally, it takes an average of 3 minutes for one, and it takes 35 minutes or even 40 minutes for all of them to add up."

"Even very top-notch examinees don't have 25 or 30 minutes to complete the multiple-choice questions, let alone the multiple-choice questions this time. The overall difficulty is beyond the sky."

"But in the end, this person is finished?"

"How long did it take?"

Sun Xingyi raised his head subconsciously and glanced at the clock on the blackboard, only to see that the time was pointing to 2:10.

That's right, it's ten past two.

The normal math time for the college entrance examination starts at three o'clock in the afternoon, but this time the entrance exam is set at two o'clock.

That is to say...

Now the exam is only 10 minutes away.

In just 10 minutes, this person finished twelve multiple-choice questions and filled them on the answer sheet. On average, the time for one question was less than 1 minute.

Then, the fill-in-the-blank questions began.

This……

Would it be too unbelievable?

Even though Sun Xingyi, as a senior math teacher, was usually prudent and prudent, he was dumbfounded at this moment.

If the answerer changes to another person, he will definitely leave with a glance, and will never stay longer.

After all, there is one and only one answer that can be done so quickly, and that is to learn from the water and write scribbles.

But at this moment, he did not leave, but cast his eyes heavily on the student's answer sheet in front of him.

Don't ask why.

just because...

The student's name is Lin Bei.

Real Lin Bei, Sun Xingyi didn't know each other. After all, he didn't teach Classes [-] and [-], so how could he know him face to face?
But he must know Lin Bei's name.

After all, since the last monthly exam, Lin Bei immediately resounded throughout the entire No. [-] Middle School, and became a top academic god comparable to Zhao Qinghan. How could he have never heard of the name of the academic god Lin Bei?
There is no doubt that Lin Bei is very strong.

Otherwise, the last monthly exam couldn't be tied for the first place in the school like Zhao Qinghan, and with full marks in all subjects.

But no matter how strong Lin Bei is, it's impossible to solve the questions so fast, right?

In just 10 minutes, the twelve multiple-choice questions were solved, and I went straight to the fill-in-the-blank questions?

Not to mention anything else, just at this speed, even his senior math teacher is the kind to be beaten.

Immediately, Sun Xingyi became very interested.

He didn't leave either, but just stood behind Lin Bei, stretching his neck and looking down.

He wanted to see if Lin Bei did the questions so quickly, did he get everything right.

After all, although it is very important to be fast, the most important thing is to be fast and correct, otherwise it is useless.

Unfortunately……

The first question, C.

The second question, A.

The third question, D.

The fourth question...

Well, Sun Xingyi could understand all these options, but he didn't seem to know whether he chose the right one.

After all, he just got the test paper not long ago, he hasn't started to do it, and he hasn't read the answer, so how can he know it right away?
Without paper and pen to do calculations, he can only make an estimate in his heart with a high probability. Lin Bei's answers to questions one, two and three of the multiple-choice questions should be correct.

As for the five, six, seven, eight, and four multiple-choice questions, Sun Xingyi really didn't know for a while.

After all, Lin Bei answered the questions directly on the answer sheet, and did not write the process of solving the questions on the test paper or straw paper.

to this end.

Sun Xingyi had no choice but to memorize the answer, so he returned to the podium, picked up a pen and paper and performed calculations.

It took him about 10 minutes to complete the multiple-choice questions, and he came to an unbelievable but unbelievable result, which was Lin Bei—all right.

"Hiss..."

Suddenly, the teacher Sun Xingyi took a breath and said nothing, and looked at Lin Bei, as if looking at a monster, "He, isn't he human?"

"Twelve multiple-choice questions that are so difficult can be solved in 10 minutes. Even scratch paper is useless, and the accuracy rate is [-]%. Is this something normal people can do?"

"Except for the word monster, there is really no other word to describe it. He simply didn't pay attention to this math paper, and he didn't pay attention to the teacher who produced the paper, Mr. Ge!"

At this moment, Sun Xingyi was really shocked and speechless, he could only roar hysterically in his heart.

But you thought it was over?

No, no, it's not that simple.

When this teacher Sun Xingyi finally calmed down, and returned to Lin Bei's side again, wanting to see Lin Bei's answers to the follow-up fill-in-the-blank questions, it made him climax again and again, and even his eyes widened, almost startled The son jumped three feet high.

just because...

In the short time he returned to the podium to calculate the multiple-choice questions, Lin Bei had already finished the four fill-in-the-blank questions 13-16, and even the five answer questions 17-21, and came directly to the end A big axis question.

Tsk tsk, Lin Bei has done the big axis questions!

How much time did it take?
The previous 10 minutes, plus the 20 minutes just now, are only 30 minutes in total.

In just 30 minutes, others didn't even finish the multiple-choice questions, but Lin Bei got to the last one.

Is this Red Bull?Or is it a real cow?
Anyway, Sun Xingyi, a senior math teacher, had seen countless gifted students, and he thought that he had already been immune to the existence, but he was stunned in place, feeling that his cognition was shattered.

"Lin Bei, this really can't be described by people, but wizards, ghosts, monsters and evildoers, it's amazing!"

"I just don't know if the fill-in-the-blanks and answer questions behind him are all right as well as the multiple-choice questions."

"If it is, then it is a generation of gods!"
