Chapter 7: You can only pluck wool when there are more sheep Lu Shan felt the pain of traveling back and forth to the Singularity Laboratory twice a day, which consumed 4 points. When Poincare saw Lu Shan, he said excitedly: "I have studied the problem you just mentioned and found three solutions!" The bored man worked on the only math problem in the lab for an hour. Lu Shan didn't know whether to laugh or cry. He had no doubt that Poincare could come up with ten solutions, but he didn't need them now! In the corner of the laboratory were placed the items that had been sent over: books, pens, ink, test papers, rough papers, and exercises. Lu Shan picked up all the things and put them on the table. Poincare adjusted his glasses and said in surprise: "Now I have something to do!" Instead of picking up the novel, Poincare took a piece of scratch paper and a pen and started to check something. F[u_，v_]:={Cos[u]……}. Lu Shan interrupted him, handed him the English test paper and asked him to do the test.
"Change your mind and look at the grammar." The college entrance examination around 2007 still retained the application of English knowledge, which is the so-called multiple-choice grammar questions. The test paper Lu Shan took only had multiple-choice grammar questions and cloze questions. He deliberately did not take the reading comprehension test because he was afraid that some modern social words would appear and Poincare would not understand them. Taking this into consideration, Lu Shan decided to subscribe to the Economic Review, the New York Times, the Summer Times (English edition) and some modern academic journals, so that Poincare could slowly absorb modern knowledge. Even old bottles need new water. Poincare understood what Lu Shan meant, "It's just a small matter!" Then Poincare answered the questions quickly. If the answers to English reading comprehension questions might be ambiguous, there is only one answer for grammar and cloze test. It took Poincare less than twenty minutes to finish answering all the front and back pages of the test paper. Since he had already spent the points to get in, Lu Shan certainly didn't want to waste time. After memorizing the English answers, he began to work on the mock questions for the CMO finals. When he encountered questions he didn't understand or felt awkward doing, he would ask Poincare for help in his broken English and using body language. Poincare's mental state was extremely excited. In addition to explaining everything to Lu Shan, he also extended the knowledge in many ways and made inferences about other situations. Poincare blew his beard and said excitedly: "In other words, the continuity defined by Cauchy is a property on an interval, not at a point. In essence, it means that the infinitesimal change of the independent variable on this interval produces an infinitesimal change in the function value. Cauchy considered continuity as a property of the function on an interval." As he spoke, he checked the calculations on a piece of rough paper. Mathematics is the best and easiest language to communicate. Lu Shan suddenly realized the importance of a good teacher to his students. He quickly wrote down the steps to solve the problem. Poincare nodded with satisfaction and blurted out, "Muggles are unstoppable!" He continued to read Harry Potter in his hand, and it was obvious that this was a new mantra he had just learned from the novel. Time in the Singularity Laboratory seemed to be still, at least that's what Lu Shan thought. In the laboratory, neither the scientist Yingling nor Lu Shan himself felt physically hungry, but their brains would become tired and shut down after being overused.
Time is unlimited, energy is limited. But here, you will not feel sleepy at all and will not be able to fall asleep. Therefore, although Lu Shan could not be sure whether there was the concept of time in the Singularity Laboratory, he could perceive time through the degree of fatigue of his brain. Lu Shan completed the mock exams in algebra and number theory, gained a lot of ideas for solving problems, and felt that he could barely keep up with Poincare's pace in English and could even have a conversation in English. It’s just… the English has a strong French accent, and reading each sentence is like reciting Victor Hugo’s operatic poetry. However, for the dumb English students of Xiaguo High School, it is enough to have such a sense of language and be able to master a large amount of grammar naturally in conversation. As for the French accent? unimportant. Lu Shan was just about to say goodbye to Poincare when he discovered that Poincare had picked up a piece of scratch paper and a pen and was writing or drawing something. Lu Shan didn't understand the world of mathematicians. Leaving Singularity Labs "What are you doing with this paper? I asked you to bring your monthly exam paper here! Do you think you can answer the questions on this paper?" Teacher Zhang gradually became furious. She hated two types of students the most in her life: one was those who had poor grades and were naughty, and the other was those who had poor grades but were extremely dull. Lu Shan ignored Teacher Zhang and picked up a pen and quickly wrote the answers he was already familiar with on the English test paper. Unlike memorizing the answers by rote, Lu Shan already knew the answers to every question he wrote. A few minutes later, Lu Shan handed the English test paper to Teacher Zhang, "Teacher Zhang, I'm going back to the classroom." Teacher Zhang was furious as he watched Lu Shan leave. "What nonsense are you writing..." Teacher Zhang looked at the test paper and shut up before he finished speaking. This discarded test paper was one of the extra copies of the "Huanggang College Entrance Examination Mock Paper", prepared for students as weekend homework. It was more difficult than the monthly exam. How could Lu Shan do this? "You are just confused." Teacher Zhang said silently. After all, there is a 25% chance of guessing ABCD correctly. But the more he read, the more shocked Teacher Zhang became. Lu Shan got all the answers right, including the fifteen grammar multiple-choice questions and twenty cloze questions! What an international joke. Teacher Zhang stood there in astonishment, and then became even more angry. Lu Shan must have done this test before and was deliberately trying to piss him off. "I can't teach this student! What kind of attitude is this!" If Teacher Zhang wasn't about to give students special lessons, she would have immediately gone to Lu Shan to find out what was going on. Back in the classroom, Lu Shan thought that he could set up a tutoring class for the poor students in mathematics, physics, chemistry and biology and use all his time to tutor the students. There are many children from wealthy families in Jiangzhou No. 100 Middle School. Many students seek tutoring from teachers inside and outside the school. The tuition fee for one class has reached more than 200 or even yuan. In 1600 when the average wage per capita in Jiangzhou City was only 07 yuan, this was not a small amount, not to mention that what the teachers taught might not be that good. On the contrary, Lu Shan usually plays football with poor students such as Zhang Yong and Yang Chuan, and they have a good relationship. Moreover, he is also a student and knows what students lack when learning a certain knowledge point and why they lack it. The effect of tutoring students yourself will definitely be better than that of a teacher. The highly proactive Lu Shan set his sights on Zhang Yong, who was scratching his head and hesitating while working on the exercises.
Zhang Yong was struggling with a probability problem. The dandruff on his exercise booklet was piling up into a mountain, and his thumb nail was almost gnawed bald, but he still hadn't figured it out. He had just gone to the classroom office. Mathematics teacher Wang's desk was already crowded with students who had questions. It would probably be the end of the get out of class for Zhang Yong when it was his turn. Moreover, this multiple-choice question should be very simple, and Zhang Yong was afraid that Teacher Wang would criticize him. Ask other students? Su Ming did not come to the evening self-study class and had been attending a tutoring class outside the school. His deskmate Xu Hong made it clear that she did not know the answer, and the other students were also busy reviewing and did not want to waste time. Those who were willing to chat with him had worse grades than him, and even wished that Zhang Yong’s grades were as bad as theirs so as to improve their class ranking. Just as Zhang Yong was chewing on another finger, Lu Shan patted Zhang Yong on the shoulder and said, "I'll tell you." At this moment, Zhang Yong felt very happy and tears almost burst out, thinking that the chicken leg he had eaten in the afternoon was not wasted! Next time, I must invite Lu Shan out to eat his favorite McDonald's children's meal! Xu Hong tactfully gave up her seat. Lu Shan smiled apologetically and said to Zhang Yong, "Actually, this question is very simple!" Ever since Lu Shan entered the classroom, Shen Qian wanted to ask Lu Shan whether Teacher Zhang had agreed to tutor him in English. But just as he was about to open his mouth, he saw Lu Shan staring at the fat man Zhang Yong infatuatedly, and then he sat down over and started explaining the problem to Zhang Yong. Shen Qian couldn't understand! What was going on? Why did Lu Shan like to rub against Zhang Yong? In the next class, the sound Shen Qian heard most from Zhang Yong was. Lu Shan: “This question is actually very simple!” and Zhang Yong: “I understand! I finally understand!” Lu Shan explained the questions to Zhang Yong very seriously and patiently, which had a good demonstration effect. Many students in the class would go to Lu Shan for help when they encountered science problems that they didn't understand. Lu Shan answered them all patiently. When Lu Shan lectures, he uses different explanation methods based on the knowledge mastered by different students. For those with a poor foundation, he starts with the most basic definitions or theorems, while for those with a better foundation, he explains more about the ideas of solving problems. Many students feel that Lu Shan explains questions to them better than their teachers. The teacher speaks at a fast pace and they may not understand what he/she says, and those who don’t understand don’t dare to ask a second time. Lu Shan’s explanation is step-by-step and clear, and you can continue to ask questions even if you don’t understand. [Remaining academic and technological points: ] very good! After the self-study class, Zhang Yong said, "Lu Shan, you explain the questions to us. This is a waste of your time. Isn't it a bad idea?" "That's right, Lu Shan, you see we have wasted two classes of your time, and we don't know how to thank you." Yang Chuan also gained a lot today. Lu Shan smiled and said, "I have gained a lot from explaining the questions to you. Let's make progress together." After hearing this, Shen Qian rolled her eyes. Lu Shan almost got full marks in math, physics, chemistry and biology, how could he make further progress! No matter how much progress you make in math, you can't get 151 points. The things you should improve on the most are English and Chinese, okay? "You can explain the questions to us in the future and we will treat you to a meal." "That's right, Lu Shan! I can't always take up your time." very good! Lu Shan said with embarrassment: "It's not that I can't eat, but I always eat in the cafeteria..." Zhang Yong understood immediately: "If I can improve my math by 10 points, I won't treat you to a meal in the cafeteria anymore. I'll treat you to a meal outside and a Coke every day!"
Lu Shan: "It's not impossible to eat stir-fried dishes, but it's not convenient to eat out all the time..." The second-generation rich man Yang Chuan quickly said, "Oh, what's the point of eating? Money is the only measure of value." "I got 54 points in math and 132 points in comprehensive science in this monthly exam. My dad said that he would give me 200 yuan for every point I improved in the first test!" "Just now, Lu Shan explained some knowledge points to me. I think it's better than what the teacher said, and I understand it. If Lu Shan can spend some time every day to help me answer my questions, I will give you 50 yuan for every point of progress I make!" "Yes, yes, yes! I agree! I don't have much pocket money, but I can pay for Lu Shan's meals and drinks every day." It’s the third year of high school now, and even poor students are anxious to give it a try, at least to get into a bachelor’s degree. Most people come from well-off families and don’t mind spending a little money. Just now, Lu Shan's way of explaining the questions was better than the teacher's. Everyone could understand him, but no one could understand what the teacher said. It costs one or two hundred yuan to ask the teacher for tutoring per class, so it is better to ask Lu Shan. Lu Shan thought for a while and said, "Okay, we will set up a study group starting tomorrow. You can come and ask me questions during your free time or during your study time when the teacher is not teaching." "Everyone, give me your recent exam papers tomorrow. I will analyze your weak points and develop a scientific review method for you." The students were very happy! At this time, Shen Qian suddenly said: "I want to join the study group too." I beg you to read my book and recommend it to me. These two are very important during the period of publishing a new book! Thank you to all the old friends for joining us! Thanks to MAMXe for the first monthly ticket, and thanks to everyone for the recommendation votes! (End of this chapter)
