The last subject of mathematics. Pen & Fun & Pavilion www.biquge.info

Zhao Hua moved a small bench and sat next to Liu Chen, but his attitude was very relaxed, not as strict as before, Liu Chen said: "Teacher Zhao, where is your electronic dog, why don't you check it for me?"

Zhao Hua already knew that the math problem solver this time was Zheng Laowei, an old guy who couldn't afford to die, and said with a smile: "This math test paper, if you can find someone to cooperate with you to cheat, it can be regarded as your ability." ”

Liu Chen didn't think so, how difficult could it be if he said it so mysteriously?

After the test paper was issued, about 99% of the students' first reaction was dumbfounded, the first multiple-choice question, they couldn't understand the question, and the remaining 1% of the students couldn't understand any of the questions.

About half an hour later, more than half of the students in the first five exam rooms were as sad as their father who had just died, and their self-confidence instantly became negative, and they repeatedly asked themselves, am I really not a scumbag?

These questions are really brain-burning, which guy who lacks great virtue comes up with questions.

An hour and a half later.

"Students, there is still half an hour, please hurry up. Li Ping paced back and forth in the examination room to remind everyone.

Not only in the 4th exam room, but most of the students began to panic when they heard the countdown, and the further they went, the more panicked they became.

In the first examination room, there are even people who have not made a big question yet, and even the 80 points of the previous multiple-choice questions and fill-in-the-blank questions are not guaranteed to get 60 points, which can easily exceed 120 points, but now it is difficult to pass a calculation!

No matter how strong the quality of the heart is, I immediately panicked, and the better my grades usually are, the more panicked I am at this time.

Meng Qingqing, who was sitting in the front row of the first examination room, also frowned, she did not do it ideally, the solution idea of the first big question is not complicated, but the amount of calculation is too large.

Analytic geometry with equations to solve, make a few auxiliary lines, involving several lines, circle equations, the head will be blinded, in case the calculation is found in the end of the answer to the end, what kind of collapse will be.

Meng Qingqing's psychological quality was calculated, Xiao Guoping, who was in a row with her, was obviously breathing heavier, the pen in his hand was constantly writing, and his thoughts were confused.

After all, he is still a sophomore in high school, he does not practice enough exercises, his personality is too proud, and he is the most vulnerable to blows.

A genius girl can't withstand the blow of math not being a hundred.

The only person in this first examination room who can still keep his face unchanged is Tian Zhiguo, who is known as the little prince of mathematics.

Twenty minutes to go!

The vast majority of students haven't even made a big question, the mood is extremely collapsed, the heart is racing, every minute and second is extremely tormented, more than ten seconds will look at the time, I really can't wait for this moment to open my brain, I can't figure out the problem to solve.

However, the reality is very cruel, the more impatient the more useless the work, and the hand that lists some calculations is already shaking.

The most relaxed and leisurely person in the 24 exam rooms is Liu Chen, difficult, this question is really difficult!

But what kind of attainments did Liu Chen have in mathematics? If he had listened to the persuasion of a well-known mathematics professor at Jianghai University to specialize in mathematical conjectures, he would have been a well-known mathematician, and this simple elementary mathematical thinking would be pediatric in his opinion.

It's no different from college students looking at elementary school math problems.

Sister Fan was already safe and promised Teacher Gu, Liu Chen did not hand in the paper in advance, but closed his eyes and pondered, and closed the test paper pen without moving for almost half an hour.

Zhao Hua glanced at him and thought disdainfully: "You just pretend, when the time comes, I will accept your test paper immediately." ”

……

"Students, there are still five minutes, sort out the test papers, check and fill in the gaps, when the time is up, everyone sit in their seats and don't move, and then leave after collecting the test papers. The invigilator reminded him almost at the same time.

In the 4th examination room, Liu Chen was still closing his eyes and recuperating.

Zhao Hua really wanted to laugh when he saw him like that, and said proudly: "If you can't do it now, you can't do it, and it's useless to struggle, except for the multiple-choice questions, there is no big question that can be done in five minutes, so it's better to simply give up, check the questions that have been done, and strive to score." ”

The invigilators in other examination rooms are also very puzzled, especially in the first three examination rooms, this exam, so far, none of them have submitted their papers in advance.

The students all buried their heads in contemplation, as if studying the wordless heavenly book, and one by one they bit the pen in their hands.

After the teachers reminded the time, a female classmate in the second examination room who was a little weaker in psychological quality actually cried.

Since he was a child, he has been a good child in the eyes of his parents, a good student in the eyes of his teacher, and there are countless bars on his arms.

is such an extremely proud girl, who finally couldn't bear the pressure of the upcoming exam time, and actually cried.

The first ten examination rooms were almost all the heavy breathing of students collapsing, and there was a smell of sweat, which student was not a bead of sweat in his head, his eyes were hairy, and his whole body trembled, and he did too badly in the exam.

Bell ...... , the bell rings for handing in.

Zhao Hua was the first to rush over to collect Liu Chen's test paper, and when he got it, he wanted to open it and take a look at the big questions behind.

Liu Chen covered his hand and said with a smile: "Teacher Zhao, this is not very in accordance with the rules, let's seal it." ”

Zhao Hua smiled, now I know that it's embarrassing, okay, I won't read it first, seal it, the ugly daughter-in-law will see her in-laws sooner or later, and your test paper will be reviewed after all.

After resting for a while, Liu Chen stood up and walked out of the examination room, many of his classmates had similar expressions, cold sweat flowed from their foreheads, and their expressions were stunned.

Just a few steps away, I saw Du Ning walking out with his schoolbag on his back, and when he saw Liu Chen, a little smile appeared on his bitter face, and he said worriedly: "Boss, how did you answer?" Originally, I thought that I could get 110 points in the exam this time, but now I'm afraid that 80 points are difficult to get." ”

"This time the question is difficult, if you can exceed 80 points, it is quite good, I estimate that the average score of the whole grade this time is probably less than 60. Liu Chen patted him on the shoulder and comforted him with a smile.

"Really?" Du Ning couldn't believe it, mainly because he almost didn't do the next big question, and he couldn't fully feel the difficulty, so he wrote most of the steps on the second big question.

Liu Chen nodded.

"It's going to hang. As soon as he came out of the examination room, a classmate yelled, and ran to the playground, looking a little lonely.

After the math test, the first thing the students said when they met was basically "I'm hanging, I want to hack the teacher who produced the test paper." ”

"When to go, call my brother, and I will make up for two cuts. That's what the other student would have answered.

Liu Chen and Du Ning walked forward together, and when they passed the first examination room, a person inside rushed out and happened to bump into Liu Chen, a fragrant wind wafted into his nostrils, and the man pushed Liu Chen to stand up straight and run away.

The long flowing hair flicked it, it turned out to be Xiao Guoping, just a glance, Liu Chen saw that her eyes were red, presumably the math exam was hit, and I think about it, this test paper is indeed too difficult, and the amount of calculation is too large.

"You must be wrong!" said a shrill male voice in the first exam room.

The two looked inside, at this moment Meng Qingqing and the little prince of mathematics Tian Zhiguo were arguing on the blackboard, what is the solution to the third-to-last problem, none of the students in the first examination room did it to the end, and the fastest progress was Tian Zhiguo.

This person studied the entire high school course on his own in his first year of high school, and it is said that he is now watching [Advanced Mathematics] in college, often guest as a math teacher to give lectures to his classmates, and his grades are maintained within the 20th in his grade.

"The complex limit operation of this problem, although I don't quite understand the method you said, but the result you give through this method is definitely wrong, I used the method I learned in high school to calculate step by step, and I can be sure that the result is correct. ”

Meng Qingqing drew a stroke on the blackboard and insisted, his waist-length long hair was tied up, and his slender neck became more and more obvious, like a proud little swan dancing ballet.

Qian Shuai stood aside, with the intention of helping Meng Qingqing, and said: "Qingqing is right, you are not wrong, don't fight anymore." ”

Tian Zhiguo's bull's eyes widened and shouted: "Shut up, I don't need you and the mud."

Qian Shuai blushed wryly, he quickly wrote a formula, and said conceitedly: "This problem is very complicated to do with [Elementary Mathematics], and the amount of operation is also very large, in the university textbook [Advanced Mathematics] there is a formula for finding the transformation limit called Lopida's law, if the numerator and denominator is the limit of type 00, you can find the derivative and then the limit at the same time, the result is the same, the result made by this method will never be wrong, Meng Qingqing, you must have done something wrong in this question." ”

The two argued again, they didn't give an inch, and the other classmates didn't dare to interject when they watched, and they didn't make an answer to this question.
