A big question worth 15 points, if this question can be won, Lin Ming's chances of succeeding in the high test will be half more.

His eyes were constantly pondering the topic, and he soon tried to solve the first question.

But after solving the first question, Lin Ming always felt that something was wrong, and read it carefully, and that feeling always existed, interfering with his thinking of solving the problem. As for what is wrong, I can't say it. If you put it on scratch paper, you may have results, and his mental arithmetic skills are not outstanding.

Unable to think of it, Lin Ming began to calculate the first question again, and finally came to the same conclusion as before. After going over and over again, he was wasting time and delaying the solution of the problem later, so he simply ignored it and began to solve the second question.

The idea of the second question is not difficult, according to the idea of the first question, and then translate the function graph three units to the right along the X axis, and let the intersection point with the Y axis after translation be C, and the vertex is P, and the conclusion can be drawn.

But if he continued to do it, Lin Ming always felt that there was something wrong, but he couldn't say it.

As the third question is solved more and more deeply, this feeling grows bigger and bigger. Looking around, he saw that many people around him were also in this distress. Some people are staring at the test papers in a daze, and some people are constantly doing draft calculations, wondering if everyone is worried about the last big question.

It took four or five minutes for Lin Ming to finally finish the third question.

He breathed a sigh of relief, and his eyes kept on the fourth question. The last big question is very difficult, the first and second questions are 2 points and 3 points, the third question is given 4 points, and the last question is 6 points, which seems to be a lot of points. But the difficulty is getting bigger and bigger, at least by the fourth question, Lin Ming is stuck here.

He kept looking at the questions, and the time passed slowly, and there were only 15 minutes left before the end of the exam, and for him, 15 minutes was a sign of whether he could score these 6 points, so as to make himself step further into the door of a high school. But the more the subject was solved, the more uneasy he became. Until the end, Lin Ming also began to wonder if he had solved the previous question wrongly, and went back to the first and second questions, and began to calculate the answers again. It took another two minutes to do the math, and there was nothing wrong with the conclusion. His math level improved not during the two months of May and June, but during the two months of summer vacation in July and August.

During this time, he not only systematically tutored all the courses pulled down by the first year of high school in cram school. With the help of Zhang Shao'an, Liu He and An Ran, he learned a lot of mathematical logical thinking and problem-solving methods. With the help of a large number of brushing questions and Zhang Shaoan, he already has his own thoughts on logic problems.

Using the way he learned to solve the problem, after Lin Ming calculated that there was no problem with the results of the first and second questions, he frowned and looked at the fourth question, looked at it for half a minute, and then returned to the third question, and suddenly realized: "The teacher of the first high school is too perverted." ”

He said this involuntarily, although his voice was small, but in the quiet examination room, like the sound of firecrackers in the silent night, it exploded countless serious students, who looked at him angrily.

Even the invigilator walked over slowly, signaling him to be quiet with his eyes. Lin Ming hurriedly gave an apologetic expression and lowered his head to solve the problem.

With 10 minutes to hand in, he didn't have much time left.

If Lin Ming didn't see what was in it at first, forget it. This big question, 15 points can only be sent out. But now that you can see it, you still have to fight for these 15 points. However, although he saw the way, whether he could solve it or not depended on whether God favored him.

In addition to the lack of time, this question is also a bit perverted as he said. According to Lin Ming's understanding, Zhang Shaoan and Zhou Yunkai will definitely not be difficult for them when they come over. But if Liu He and An Ran are not careful, they may have to be planted on this big problem. Because this big question is actually a rare interlocking multi-trap question.

The so-called trap questions are known to everyone, and they are a common trick in the exam, using the sequential way of thinking when normal people face the questions to set traps one by one, just like magic, the answerer will follow the train of thought of the exam questions, watching the magician stretch out his right hand, holding the box that attracts your attention, but in fact, the left hand is the mystery of magic. This type of question tests the logic and thinking activity of the answerer, because this type of question appears most often in various exams. The more rigid the thinking, the most likely to get stuck in this kind of trap problem, only the flexible use of the mind, can jump out of the shackles of thinking, in order to come up with the answer.

And the general trap question is not difficult, but this question even Lin Ming himself didn't understand at first. Until the more I continue to do it, the more I feel that something is wrong. Because according to the normal way of thinking, when he reaches the fourth question, he will find that according to the previous solution ideas, the answer he gets is not reliable at all.

How untenable?

The last two questions are the results that can only be obtained with the assistance of the answers to the first and second questions.

But there will be a loophole in it, that is, if B is equal to 0, the previous y1 is solved as 2 in the first problem, according to the conclusion that a is a constant, if the third problem is solved, the function is the opening upward, the parabola is above the y axis, and the answer to the fourth question will collapse directly.

In other words, if the student does this according to the normal problem-solving idea, then all the previous efforts will be in vain and in vain.

That's why Lin Mingcai said that the teacher was perverted, and the students racked their brains to finally get the first and second questions that were a little simpler. Even if the third and fourth questions are a little more difficult, you can score 5 points out of 15 points. But if you can't solve the third and fourth questions, the first two questions are actually wrong. And this question is actually reversed, and the general trap question is only one or two traps, such as turning the solution idea of 1234 into 1324, this question directly gives you four, one link and one ring, you have to start with the second and third questions, and then push the first and fourth questions backwards. So much so that no matter which part of the student makes a mistake, the whole question will collapse.

This kind of play, if you change to other students, it is estimated that you have to find the teacher to draw a knife to play with your life. That is, Lin Ming saw the problem at a critical time, and only then could he find a way to make up for it.

But now there is not much time for him, whether he can untie it or not depends on the will of God.

Lin Ming worked hard to write the book, and began to write the answer directly on the answer sheet. Only in the process of arithmetic is it calculated on scratch paper. After a series of calculations, the answer is directly obtained, and it is transcribed according to the calculation format on the answer sheet. In just 10 minutes, his hand speed was extremely fast, and he didn't put away his pen until the last ringing of the wind.

Lin Ming breathed a sigh of relief, and when the bell rang, he had to stop writing and wait for the invigilator to collect the papers. But he finally finished writing this question, but he didn't have time to review, whether the answer was correct, whether there was a calculation error in the process of solving the problem, there was no way to check, whether the result was right or not, it depends on God.

Lin Ming raised his head, and it was only at this time that he realized that there was a person standing beside him all along. It was the middle-aged invigilator, he looked at Lin Ming with blazing eyes, and seemed to see the incomprehension in Lin Ming's eyes, and the middle-aged teacher showed a kind smile.

While taking away Lin Ming's test papers, he said casually: "I have good news for you, my name is Dai Zhou, the head teacher of Class 13 of the first year of high school, the perverted teacher in your mouth, and also your marking teacher." ”

He patted Lin Ming on the shoulder and made a self-conscious expression.

Lin Ming was frightened at that time, revealing a smile that was more ugly than crying.

The people around him looked at him with pity, although the first high school has not yet opened the class division system of ordinary classes and key classes, Dai Zhou's reputation is still very great. National special-grade teacher, but also the deputy leader of a high school group, the Yuncheng Education Bureau will award outstanding teachers every year, a high school this year to report to the people there is Dai Zhou, and the reason why he can fight his way out of the encirclement in such a top teacher environment is because last year he took the senior high school, out of a class of undergraduate students, even the bottom of the two B class. You can imagine how arrogant such a star teacher is, scolding him in front of such a person is a pervert, and he can't stand it if he is changed.

Lin Ming didn't know that the teacher who wrote the question and the teacher who scored the papers was him, but Dai Zhou was still his invigilator, and he caught the scene in public.

This made Lin Ming uncomfortable, his foundation was already thin, and it was very difficult to get to the next level. Now I actually scolded the teacher for being perverted in the examination room, and I was caught by the teacher. If Dai Zhou's heart is really so small, he will not let go of the problem and brush it down for you directly, there will be no place to cry, but now that the rice has become porridge, there is no way to recover it. Lin Ming could only look at Dai Zhou with a pitiful expression, Dai Zhou put away the test paper behind him, and when he came back, he saw his expression, and a smile appeared on the corner of his mouth, which made Lin Ming's uneasy mood a little better.

Anyway, he is also a high-level special teacher, so his belly should not be so small.

Lin Ming sneered.

However, he didn't dare to chat with Dai Zhou, and waited for the teacher to finish collecting the papers and announcing that the exam was over, before he got up and went to the podium to get his mobile phone and leave.

Out of Shaw Building, he originally wanted to find Ye Shishi.

If you throw away those friends who have played since childhood, Ye Shishi should be regarded as one of his few friends in Yigao. It's summer vacation now, and none of his friends are at school, so Lin Ming plans to go to Ye Shishi to inquire about Dai Zhou's personality and see if he is a cautious person.

As a result, as soon as I got out of the Shaw Building, I saw An Ran standing at the door of the building.

When many students passed by, they saw her bathed in the sun, and the warm sunlight sprinkled on her short hair, as if she had crossed a layer of golden halo, like a goddess standing there, which made people involuntarily stunned.

Someone secretly asked others who she was.

Some people who know An Ran said that her name is An Ran, the first school flower of a high school.

The man said, it turns out that she is An Ran, I heard of her when I was in 9, I didn't expect her to be more beautiful than rumored, if she can be my girlfriend, she will be willing to die.

Others disdainfully said that they didn't pee to take care of themselves, and they could have a reinforcement company chasing An Ran in a high school, I heard that Song Lei, Zhao Hao, and Xu Zihan all hit nails on An Ran. You don't look at what you look like, and you deserve Enron to be your girlfriend?
