How hard is this math test?

Just take a look at the past few questions below.

"1: Let a=0.1e^0.1, b=1/9, c=-l

0.9, then the correct size at the bottom is ......"

【A：a＜b＜c。 】【B：c＜b＜a。 】

【C：c＜a＜b。 】【D：a＜c＜b。 】

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

【A：[2,6]。 】【B：[4,8]。 】

【C：√2，3√2]。 】【D：2√2，3√2]。 】

"3 Given that the center of the hyperbola is at the origin, and a focal point 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。 】

……

See, is it hard or not?

For example, in the first question, bet on ten packs of spicy strips, at least five out of ten candidates can't do it.

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

Although it's just a big and small comparison question, it looks okay at first glance, but it's really just at first glance!

If you do it carefully, the amount of computation is not ordinarily large, and you need to use extreme scaling, which is comparable to solving problems.

Of course, there are also simpler ones, such as using the Taylor formula, but the formula doesn't seem to be learned in high school.

So you said the question was overrun?

I'm sorry, but it's really not too much.

But if you want to say that you don't exceed the outline, the amount of calculation can be comparable to that of solving questions, don't you deliberately make things difficult for people?

Of course, with Zhou Buyi's third grade and comparable to the strength of a god, this question can definitely be done, but the time it takes may be a little longer.

But the multiple-choice questions take a long time, and the time will not be enough later, which Zhou Buyi cannot tolerate.

Let's take a look at the second question.

The range of values for the area of the triangle is found.

It's also not difficult at first glance, but if you calculate carefully, it is estimated that you can count people as crying.

If there is no easy way, the amount of computation is only higher than the first one.

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

Nima!

According to the previous exam model.

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

Even if it is not the big shaft of the press, as the penultimate finale, it is more than enough.

After all, the problem involving the curve equation is more complex and computationally intensive than the second one.

But this time, the exam was put in the third multiple-choice question, didn't this especially crush the candidates on the ground?

Even a god-level figure like Zhou Buyi, when he saw these questions, he was a little trembling and his teeth chattered, not to mention other ordinary candidates.

Moreover, these are only three questions.

As we all know, whether it is a choice, a fill-in-the-blank, or a solution, it always becomes more difficult the further you go.

This is the case for all two or three ways.

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

As soon as he thought about it, Zhou Buyi's mentality couldn't be stabilized.

Of course, it would not be difficult to say that these questions are really comparable to competitions, after all, they are completely different from each other.

But the overall difficulty is really not low.

I want to finish this volume within two hours, including Zhou Buyi, I'm afraid few people can do it.

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

"What the hell is going on?"

"Aren't the people in the paper group crazy?"

"This choice of one, two, and three questions is not enough as the last big axis, but as the finale, it is more than enough, and it is difficult for ordinary candidates to do it without seven or eight minutes together."

"But as a result, there are three questions like this exam at once, and I don't say anything, and I put them at the beginning?"

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

"Needless to say, this is definitely a roll made by Ge Tianxing Ge Lao himself, except for him, everyone else has no such ability, and they don't dare to have this ability, after all, they are afraid of being scolded......"

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

After all, he is also a senior math teacher in the school, and he has led several classes, and he can see at a glance that the difficulty of this paper is more than all previous exams.

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

Perhaps, you can catch up with the college entrance examination papers of 03.

But that's the most difficult paper in the college entrance examination!

And now it's just a small ten-school joint examination in Xiaolincheng, and it's so difficult.

Almost at the first time.

He began to feel a moment of silence for the candidates in his class.

There is no doubt that this mathematics test will inevitably hit countless candidates hard and even feel collapsed.

Not to mention high scores, there are not many people who can get 100.

After all, even as a math teacher, he couldn't get much of a score for just two hours.

However, in the next second, when he invigilated back and forth to Lin Bei's side, his pupils suddenly opened.

“？？？”

“？？？？？？”

"This, what's going on? This, how is this possible? Am I dazzled, or am I dreaming??? ”

"How could this person be so fast, and in such a short time, the multiple-choice questions were completed?"

"Eight single choices, four multiple choices, one twelve, normally speaking, it takes an average of 3 minutes, and all add up to 35 minutes of basemaking, and even 40 minutes."

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

"But as a result, this person has done it all?"

"How long did it take?"

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

That's right, it's two points and ten.

The normal mathematics time for the college entrance examination starts at 3 o'clock in the afternoon, but this time the joint entrance examination is set at 2 o'clock.

Other words......

It's only 10 minutes before the exam starts.

In just ten minutes, this person completed the twelve multiple-choice questions and filled them in on the answer sheet.

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

This......

Isn't it a little too incredible?

Even though Sun Xingyi, as a senior math teacher, has always been steady and respectful on weekdays, he was stunned at the moment.

If the respondent were to change the question, he would have glanced at it and gone, and would never stay longer.

After all, there is only one answer to make such a quick answer, and that is to learn one and write it scribble.

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

Don't ask why.

Just because ......

The student's name is Lin Bei.

Lin Bei Zhenren, Sun Xingyi doesn't know him, after all, he doesn't teach the third or fourth class of high school, how can he know him face to face?

But Lin Bei's name, he must know.

After all, since the last monthly exam, Lin Bei immediately resounded throughout the entire Third Middle School, and became a top god of learning comparable to Zhao Qinghan, how could he not have heard of the name of Lin Bei, the god of learning?

There is no doubt that Lin Bei is very strong.

Otherwise, the last monthly exam would not be tied for the first place in the school like Zhao Qinghan, and it was a full score in all subjects.

But no matter how strong Lin Bei is, it is impossible to do the questions so fast to such an incredible extent, right?

In just ten minutes, I got 12 multiple-choice questions, and I went straight to the fill-in-the-blank questions?

Not to mention anything else, at this speed, even he, a senior math teacher, is the kind that is beaten.

Suddenly, Sun Xingyi became very interested.

He didn't leave, but kept standing behind Lin Bei, and stretched his neck to look down.

He wanted to see if Lin Bei was doing the questions right so fast.

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

It's a pity......

Question 1, C.

Question 2, A.

Question 3, D.

Question 4......

Well, Sun Xingyi can understand all these options, but he doesn't seem to know whether he chooses the right one or not.

After all, he didn't get the paper for a long time, and he hadn't started working on it yet, and he hadn't read the answer, so how could he know it immediately?

On the premise that there is no paper and pen to calculate, he can only have an estimate in his heart with a high probability that Lin Bei's answers to the first, second and third questions of the multiple-choice question should be correct.

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

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

For this.

Sun Xingyi had to memorize the answer, and returned to the podium, picked up pen and paper to perform a calculation.

It took him about twenty minutes to finish the multiple-choice question, and came up with an unbelievable result, that is, Lin Bei - all right.

"Hiss ......"

Suddenly, this teacher Sun Xingyi gasped and didn't say anything, and looked at Lin Bei's gaze, as if he was looking at a monster, "He, can't he not be a human?" ”

"Twelve such difficult multiple-choice questions in ten minutes, even scratch paper is useless, and it can still be 100% accurate, is this something that normal people can do?"

"Except for the word monster, there is really no other word to describe it, he simply didn't put this math paper in his eyes, and he didn't put the teacher who produced the paper, Uncle Ge Lao, in his eyes!"

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

But you think that's the end of it?

No, no, no, it's not that simple.

When this teacher Sun Xingyi finally calmed down, and touched Lin Bei's side again, wanting to see Lin Bei's follow-up answers to fill-in-the-blank questions, he even made him tall/chao without saying anything, and even widened his eyes, almost jumping three feet high in shock.

Just because ......

In the short time when he returned to the podium to calculate the multiple-choice questions, Lin Bei had already completed the four fill-in-the-blank questions from 13-16, not to mention, and even the five solution questions from 17-21, and came directly to the last big axis question.

Tsk, Lin Bei has done the big axis problem!

How much time did it take?

The first 10 minutes, plus the previous 20 minutes, are only 30 minutes in total.

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

What the hell is Red Bull? Or is it a real cow?

Anyway, Sun Xingyi, a senior math teacher, has seen countless genius students, and he thinks that he has long been immune to existence, but he is stunned in place, feeling that his cognitive outlook is shattered.

"Lin Bei, this really can't be described as a person, but a wizard, a ghost, a monster and a demon, it's just a beep!"

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

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