Chapter 7 Teacher Wu's math class

Our third grade tutor is a curly-haired man, as the name suggests, he is a curly-haired man. He is fat and dull, and has a beard growing under his nose. He looks a lot like Wu Mengda, so no matter his surname is Wang, we call him Mr. Wu , Although he was helpless, he had no choice but to be called Mr. Wu by us until graduation. Later, other teachers in the office were also confused by us, and they even started calling him Mr. Wu, so when he took his own child as Wang When it was Qingwen, everyone was taken aback. Teacher Wu teaches mathematics, but he said in his self-introduction in the first class: "Actually, I studied Chinese in college. Although I didn't do well in it, I managed to graduate. But just now the principal told me, Now the school lacks a math teacher, so I asked me to take the middle school math for a while, I want to say forget it, what can I do? So I will teach you math."

When he said this, the whole class opened their mouths. What is this guy talking nonsense about? "However, I just looked through the mathematics textbook for the third year of junior high school and found that I don't know how to do it. This is troublesome. I should start teaching mathematics from the first year of junior high school, but what can I do? So everyone opened the textbook, the monitor is Who?" Teacher Wu usually said dumbfounding nonsense, and the jaws of the whole class almost dropped. Ha Bang is the class monitor, but of course he doesn't have to raise his hand or even wake up. Everyone looked at Ha Bang lying on the leather chairman's chair, and Teacher Wu immediately knew who the class monitor was.

"Who will tell the monitor to get up, and the monitor will read a passage from the textbook." Teacher Wu scratched his head. "Teacher!" Yang Dingfeng raised his hand. "Why?" Teacher Wu. "Let's call it a student on duty." Yang Dingfeng made a wise suggestion in order to take the overall situation into consideration. "Well, what can I do?" Teacher Wu shrugged. The first math class in the third year of junior high school ended in a strange situation where the students on duty were reading math textbooks. Can you imagine such an absurd plot?I must admit that I am not very good at mathematics, so I was not only shocked when I encountered this situation of "reading mathematics textbooks in class", but I almost couldn't help peeing in class... I couldn't understand anything, even trigonometric functions. The formulas are all read once, and I can't help but start to worry about the country's mathematics and science education. The country's subjugation is just around the corner.

I wiped my tears and looked to the side, almost everyone was doing their own thing, the boss’s seat was empty, he probably went to patrol the campus, the fat woman was knitting a sweater, Yang Dingfeng was playing checkers with Xie Jiayun, Lin Caiyou was watching from below In the yellow pictorial, Lin Qianfu was secretly kicking the shuttlecock, and Tata just jumped rope in the corner alone (but her situation is special, she will have a competition next week). Only Wang Guowei shook his head following the text read by the students on duty with relish, and recited silently.He was really the only beneficiary of this pedagogy.

After a week like this, the mathematics progress of our class obviously surpassed that of other classes. There is still one and a half months before the midterm exam, but we have already "completed, all, read, finished, and completed" the scope of the exam. Teacher Wu feels this. I am very relieved that I still read his mathematics textbook for the first grade of junior high school in class. But there was one person who couldn't stand the situation. In the chanting class of the second week, the two students on duty were still taking turns reading the exercises in the math textbook...

"Teacher!" Lin Junhong raised his hand. "Why?" Teacher Wu raised his head and looked at Lin Junhong, a good and diligent student. "Teacher, I don't think this kind of teaching method can absorb anything." Lin Junhong stood up bravely and said, "I think we should start from the basics, otherwise I just read it and don't know how these formulas come from." .” Teacher Wu nodded and agreed. "Okay, students, what can I do? Turn to the first page, and let's start from the most basic." Teacher Wu scratched his head. Next, Teacher Wu spent an hour explaining the author's life, that is, the history of the National Editorial Office. I found my fists gradually clenched, and my anger was about to explode.

Then, Mr. Wu cleared his throat and talked about the origin of trigonometric functions and the importance of trigonometric functions. "This trigonometric function is basically composed of two words. Since triangle is an adjective, the function has to be a noun. If you want to learn trigonometric function, you must understand its importance, right? When it comes to trigonometric function, you have to Mention the triangle, everyone just think about it, if there is no triangle in this world, what kind of impact will it have? It’s inconvenient! Is there any student who wants to talk about the importance of the triangle?” Teacher Wu soon didn’t know what to say What, I had to talk nonsense.

There was silence in the audience, except for the creaking sound of more than fifty fists clenched at the same time. "Extra points." Teacher Wu shrugged and took out the name book. Wang Guo raised his hand excitedly. "Say." Teacher Wu's expression was greatly inspired. "If there were no triangles, there would be no set pieces!" Wang Guo said. "Very good, one point will be added at the end of the term. Is there any more?" Teacher Wu was very satisfied, and made a mark on the roll call book. Wang Guo raised his hand again, his right hand was raised high like a flag.

"Without triangles, we'd have to wear boxers!" Wang Guo said. "Very good, one more point at the end of the term. Is there any more?" Teacher Wu nodded repeatedly and smiled to himself. Two good classes were spent in this kind of nonsensical questioning and answering. I glanced at Lin Junhong who made the suggestion. He was trembling with anger and his face turned pale. A week before the final exam, some parents finally called Mr. Wu's home to protest that his teaching was too casual (in fact, if these parents came to observe, they would probably lose their shoes in anger), so Mr. Wu had no choice but to announce in class that there would be a pre-examination reinforcement.

"Yesterday, a parent called me and asked me to be more strict... What can I do? Apart from relying on the teacher to teach in class, everyone has to do exercises by themselves when they go home. You must remember that you are studying for yourself. Stay! Now we have a pre-examination group reinforcement, the students on duty sit down, and we all read the text from the first page together, and we will review the text again within three days, so that there will be no problems in the exam.” Teacher Wu said helplessly. So, we read the textbooks in unison, everyone read very loudly, the voices were full of anger and resentment, we read louder and louder, and almost shouted at the end, hoping that other classes in the school can notice our grievances .But Mr. Wu was obviously very satisfied with our large-scale text reading, and kept shrugging his shoulders in praise.

Two days before the mid-term exam, we saw that the class next door was doing the pre-examination review papers, and we couldn't help getting nervous. Lin Junhong, who was studying in Gao Zhaonan's cram school, volunteered to stay in the classroom after school and held a pre-examination sprint for everyone. One question One question is explained, and the origin of each formula is tried to be as clear as possible. I also reluctantly memorized the derivation of a few formulas, hoping to get 30 or 40 points. The mid-term exam is finally here. After finishing the Chinese and history exams, we are all shrouded in gloom, but there is also a mentality of expecting revenge: if we do badly in the exam, Teacher Wu will definitely be called to the principal Shi Hai Cut a meal. The invigilator was the math teacher from the next class, and he scanned the class with an almost sneering expression, as if to say: "You idiot class with that idiot teacher, you will definitely get an idiot score this time." .” Some people began to cover their faces and sob, and some people were already ready to cheat on the Internet. Only Boss Ha Bang was there as usual, and after handing over the exam papers to Yang Dingfeng, he went for a walk in the corridor and played alone. The math teacher in the next class opened the sealed kraft paper bag, took out the test paper and handed it out, only to see him sitting on the podium with a test paper, his face gradually turning blue. Then, I felt an unstoppable vibration from the back of Xu Xinyu who was sitting in front. Nervous?I looked down at the exam paper. Jingcheng Secondary School's first math test paper, the full score is calculated as 100 points Name: __________ Student ID: ___________ one.Fill-in questions (5 points per grid, 20 points in total) A triangle in trigonometry has ( ) angles and ( ) sides. I think the triangle of the trigonometric function is the ( ) word, and the function is the ( ) word. two.Short answer questions (15 points each, 30 points in total) Who is the author of trigonometric functions?Please briefly introduce the author's life and achievements. What is the importance of trigonometric functions?Give five examples and explain them. three.Detailed answer questions (40 points in total) Please silently write down the two most memorable pages in your math textbook. (20 points per page) After reading the math test paper whose scores add up to ninety at most, I found that my eyes were filled with inexplicable tears, which was a kind of emotion and a kind of twitch. "Bastard! This must be your teacher's crazy question!" The teacher in the next class suddenly roared hysterically. But a wonderful emotion has silently connected us through the examination papers. "You are not allowed to insult Teacher Wu!" Yang Dingfeng patted the table angrily. "How can you speak ill of our Teacher Wu!" Wang Guo was filled with righteous indignation. The whole class started clamoring and slapping the table non-stop. At this time, the math teacher in the next class suddenly caught a glimpse of Mr. Habang's cowhide chairman's chair, and remembered the importance of loving life, so he sat down with a gray face. Everyone also calmed down, concentrating on answering the exam. After a burst of cheerful writing, everyone's exam papers are full, and I am no exception. Later, when the results of the test were announced, only our class’s math scores were average, and it was a super high score of 87 points (the full score was only 90 points because of Teacher Wu’s calculation error). The teacher highly praised it. He didn't change his humble style, but just shrugged his shoulders: "This time, the funds are insufficient. There is no teacher subsidy for the exam papers, so no teacher is willing to do so. The principal insists on asking me for help. What can I do?" At the end of the third year of junior high school, Wang Guo was awarded a full score for "you ask me to answer". The mathematics column in the academic performance is a rare full score. The mother is so happy, even I got 86 points . Later, let me talk about Mr. Wu's incredible deeds; by the way, Mr. Wu is one of the few teachers who has not been threatened by Mr. Ha Bang's fist. Let you step on the ground" personality is still very resilient. ----------------------------------------------- Notes:
