"Attention all candidates, please put your admission ticket and ID card in the upper right corner of the table so that it is forbidden to bring any items unrelated to the examination into the examination room in the examination room, if there are candidates who need to turn in now, please put them in the bag provided in front of the podium, and read the examination room discipline ...... below"
At 8:55 Yanjing time, at the test center of Sichuan No. 1 Middle School, all candidates have been admitted. Du Bu sat on the table with his exam number attached, listening to the teacher read out the discipline of the exam room that he had heard for an unknown number of times, while slowly adjusting his breathing.
His breath is very special, longer and more dense than that of ordinary people. When you exhale, your lips open slightly, and the air flow formed a very thin line, and it took about half a minute to breathe. And with the breathing, the emotions of the whole person are more and more soothing and condensed!
This is the method of breathing and breathing that he learned in the virtual school, which is the introductory exercise method of Qi refining from cultivators who has been personally improved by the chairman of the Leshen Group! With the help of this set of exercises, Dubu quickly entered the best state of on-the-spot competition!
Not only Dubu, but almost everyone in the more than 30 candidates in this exam room is doing the same thing as Dubu! Although they are not all from Uco Middle School, their school registration is all from Uco Middle School, and more importantly, they have all studied in the virtual school!
Most of the invigilators are from Sichuan No. 1 Middle School, and in their impression, Uke Middle School is a middle school in a remote area with very poor conditions, and the student base there is also very poor, but when they really see these students today, they have a very different impression. How so? Although the exam has not yet begun, they see on the faces of these students the calmness and confidence that only belong to the top students!
Hao Hong is a mathematics teacher at Sichuan No. 1 Middle School and a principal examiner at this year's Sichuan No. 1 Middle School test center. She knew that this year's proctored exam was a little different, as the students were all students from the virtual school pilot.
About the virtual school, Hao Hong has also learned some from the Internet before, and it is very magical, what is a middle school student in Yanjing Haiding Middle School, who studied in it for a week, and his grades jumped to the top ten in the school, and a poor student from Hengshui No. 1 Middle School transferred to Wuke Middle School, which increased by 100 points in less than half a month, and the students of a certain class of a certain middle school were collectively transferred to Wuke Middle School, just to fight for a virtual school place, etc., but these things on the Internet are half-truths and half-truths, and she doesn't care too much. It's just that when she really saw these students today, she felt that it was indeed a little different, very different from the students who came out of backward schools in her impression!
After reading out the discipline of the examination room, Hao Hong began to unseal the test paper bag in front of the students with the other two invigilators, and then began to distribute the test papers. The first exam is mathematics, for an old teacher who has taught mathematics for more than ten years, Hao Hong read this year's college entrance examination papers at a few glances in the process of distributing the test papers.
"This year's exam questions are generally difficult, especially the big questions in the back, the knowledge points are very biased, it seems that this year's math exam is not good!" After handing out the test papers, Hao Hong thought to herself.
She remembered the situation of the students in her class, and according to the results of her cursory glance just now, she had already judged that the general difficulty of this year's test questions was difficult as a whole, especially the next few major knowledge points, many of which were weak links in the usual review. Thinking of this, she couldn't help but start worrying about her students.
"If this paper is made by those children in the class, Li Jiannan and Song Qian are almost sure, and the others ......" Hao Hong quickly went through the students in the class in his mind, and then shook his head. She found that except for the two top math students she just thought of, if the other students did this test paper, they might basically fail very high.
"The first subject is so difficult, not a good sign!" Thinking of this, Hao Hong's heart was a little heavy.
However, she still did not forget her main examination duties, and before the opening signal was sent, she still reminded the candidates to pay attention to filling in their names, admission ticket numbers and other information, and not to answer the questions before the opening bell rang. She found that the students were very obedient, basically did not have to say anything to themselves, and were very well-behaved.
Even, in Hao Hong's opinion, their rules are a bit excessive. You know, there are a few minutes after the test paper is sent out and before the exam starts. Although these few minutes are not long, they are enough for candidates to complete one or two previous questions. Of course, the rules of the examination room do not allow you to write directly on the test paper and answer sheet, but this does not mean that there is no workaround, as long as it is counted directly on the scratch paper. Calculate the answer first, and wait until the exam starts to copy the test paper, which is equivalent to a little more time for the exam. In the math exam, such a little time advantage is very important. Hao Hong has educated all the students in her class in this area, and she believes that other third-grade teachers are the same, and it is impossible not to teach such simple test-taking skills to students.
So, why don't they do it?
Is it true that no teacher has taught them, or are these students too honest? The reminder of his own sentence just now scared them? If this is really the case, Xu Hong feels that he is a little excessive.
Although I am not my own student, as a teacher, I feel the same way for all my students at the moment. The college entrance examination is the most important turning point in life, and in such an examination room, as long as it is convenient within the rules, the invigilators will provide it to students. After all, everyone has children, and everyone's children will take the college entrance examination.
When the answer bell rang, Hao Hong put away his thoughts just now, and said in a calm voice: "Start answering questions!" ”
After saying this, she began to sit on the podium in front of her, and condescendingly began to watch the students take the exam. At the back of the examination room, there were two invigilators who were also from Sichuan No. 1 Middle School. Like Hao Hong, they all sat on their chairs and did not get up and move around.
In the current college entrance examination invigilation room, it is rare to see those invigilators walking around. Although teachers occasionally do this during the usual exams, it is not allowed in the examination room of the college entrance examination because it will disturb the students' examination status. In addition, these teachers are experienced in invigilation, and even if they sit there, they can clearly see the students' every move, not to mention the surveillance cameras in each exam room.
Hao Hong sat in front of the podium, her gaze slowly scanning below, but she was quickly attracted by the actions of one of the closest candidates to her. Hao Hong noticed that when the bell rang for the girl to start answering the questions, she picked up the answer sheet of the math I paper and quickly wrote a few numbers on the front fill-in-the-blank.
The reason why Hao Hong noticed her action was because she wrote so fast, almost without thinking. And Hao Hong noticed that she was jumping to write, a total of fourteen fill-in-the-blank questions, she wrote four, Hao Hong's eyesight is better, she saw at a glance that the girl filled in the answer to the third, seventh, eighth and twelfth questions.
"How did this kid write the answer directly? Didn't see her calculate? Hao Hong thought a little strangely.
She has been teaching mathematics for more than ten years, so she naturally knows the amount of calculations in mathematics exams. Don't look at the previous questions just fill in the blanks, but even these questions are not so simple, and some of them require no less calculation than the later questions!
This girl, Hao Hong had just checked her admission ticket and knew that her name was Mayi, and she was a local student at Wuke Middle School. Curious, Hao Hong glanced at the four answers she had written on the answer sheet, and then flipped through the blank math paper in front of her.
In the test paper bag in each examination room, there will be two extra blank test papers, which is a backup to prevent some unexpected events, such as test paper printing problems, or candidates accidentally damage the test paper and need to replace it, etc. Most of the time, though, such an event doesn't happen. Blank test papers will be packed into a test paper bag and marked with a special marker along with the other test papers.
Hao Hong glanced at the blank test paper in front of him and looked at the fill-in-the-blank questions.
"Oh, the third problem is a trigonometric problem, which is relatively simple and has a simple algorithm." Hao Hong just glanced at the question, and roughly judged the difficulty of the question and the solution idea.
She tried her mental arithmetic, a few formulas flashed through her mind, and after a minute, she came up with the answer.
"The cosine should be 42 degrees." Hao Hong thought to herself in her heart.
She glanced at the answer sheet of the candidate named Mayi below, there were more than four answers on it at the moment, and when she was doing mental arithmetic, Mayi filled in two more answers, but this time they were written in order from the front.
She glanced at the third question, and the answer on it was exactly 42 degrees, which was exactly the same as the result of her own calculation!
"Really did it right, did she calculate it by heart?" Hao Hong thought with some surprise.
The test paper is sent to the candidate, and then the exam begins, during which there is less than five minutes, and most candidates can make one or two fill-in-the-blank questions in front of them through the calculation on the scratch paper, and especially good students can even calculate three, which is already the limit, and it is necessary to use scratch paper!
However, the moment the exam began, this little girl wrote down four answers! If these are all mental arithmetic that she uses these five minutes of time, then her mental arithmetic ability is too terrifying!
With a skeptical attitude, Hao Hong began to mentally calculate the answers to the other three questions she had filled in earlier. The remaining three questions are slightly more difficult. This is also the proposition law of the college entrance examination paper, the same type of questions are often more difficult the later you go, especially for the last two questions, the difficulty is often several times that of the previous one. If you use the difficulty terminology in the game, the first three questions are generally easy level, the middle level is normal, and the latter level is generally difficult or even hell level!
Because of this, Hao Hong has said to her students more than once that if you encounter a difficult question in the exam that requires a lot of calculations, and it is a small question in the front, and the score is not very high, then you must skip over it first and pick the simple and higher score questions in the back, so that you can effectively use your time and improve your score!
However, the four questions that this girl did in the five minutes before the start of the exam almost included these three difficult questions! Hao Hong tried mental arithmetic by herself, and found that even if it was herself, it was difficult to calculate all four questions in five minutes!
She looked at the time and counted the remaining three questions, plus the previous trigonometric problem, which took her a little over seven minutes. Of course, this is in the case of mental arithmetic, and if you use the calculation straw, the speed should be a little faster.
However, after doing the math, she quickly discovered the characteristics of these four questions. Although the difficulty of these four questions is different, they have a common feature, that is, they all have special methods and ideas for solving problems, as long as you find the right method, the amount of calculation is not large, but the process of thinking is more complicated. For the remaining questions, each of them must be calculated on scratch paper. You know, some problems that involve complex four- or five-digit mixed operations, plus calculations such as squares, are simply impossible to do without scratch paper!
Only these four questions can be answered directly through mental arithmetic! This is a conclusion that Hao Hong came to after reading all the fill-in-the-blank questions!
But how is that possible?
It's only five minutes! Even if you want to pick out four of the fourteen fill-in-the-blank questions in these five minutes, you can directly mentally calculate the answers, and then calculate the results, this is an almost impossible task! Of course, when you are young, if you are at your best, it may be possible. But she is now nearly forty years old, and her physical strength and energy are not as good as before, and although she has a lot of experience in solving problems, her problem-solving speed has slowed down!
However, even in your heyday, it is extremely difficult to do such a thing! The ordinary-looking little girl in front of her is really such a rebellious student?
With such doubts, Hao Hong once again set his eyes on the little girl in front of him who was concentrating on answering the question. At this glance, she couldn't take her eyes off it anymore!
A ballpoint pen moves rapidly on the scratch paper, formulas and equations are quickly listed and solved, and in the process, one answer after another is constantly generated and filled in on the test paper. The process seemed so smooth, free, and pleasing to the eye, Hao Hong was almost instantly captivated! )
