"Hey, the question of the first year of high school, what, do you want to make up for the shortcomings?" For Wu Bin, who suddenly wanted to learn, Liu Yushan didn't say anything to answer him, but stared at Wu Bin's eyes and asked.

"Well, I want to make it up slowly." Wu Bin nodded seriously.

"It's not an easy thing to do."

Liu Yushan said and flipped through Wu Bin's workbook, and found a few pieces of scratch paper that were sandwiched inside, as well as a few problems that had been solved.

"Yo, self-taught?"

"Well, I tried to do it in self-study last night, but there are a few questions that I really don't understand, so I came to trouble the teacher."

Hearing Wu Bin's answer, Liu Yushan nodded with some satisfaction.

"Okay, good, it's a good thing to want to learn, I don't understand this question, right, let me tell you, to do inequality problems, the most important thing is that you first have to know whether to find the maximum or the minimum value, you look at this problem, ah......"

Looking at Mr. Liu, who gave him a careful lecture, Wu Bin was a little surprised, he thought that this old pedant who had given up on himself a long time ago would definitely laugh at him, and even ridicule a few words, he was also mentally prepared, but he didn't expect to usher in a warm spring like spring.

"So as long as it's greater than its maximum, then it's bigger than it, you know?" Liu Yushan listed a formula and explained.

"Got it! It turns out that this is the solution, teacher, you are really awesome! ”

Wu Bin, who suddenly became cheerful, nodded violently, and suddenly felt that Liu Yushan's image was extremely tall.

"Poof...... Ahem, ahem. ”

Liu Yushan, who had just taken a sip of water, choked on this sudden compliment, and Wu Bin hurriedly took out two tissues and handed them over.

"Don't say these weird things in the future."

Liu Yushan, who took the tissue, wiped his mouth and glared at Wu Bin by the way.

"This is not a strange thing, I looked at the textbook yesterday and thought about it for a long time and didn't come up with a solution, I immediately understood the meaning when I heard the teacher, I really thief." Wu Bin's face of worship when he spoke, this was not pretended, but he really felt that Liu Yushan, who had easily solved this problem, put on a layer of great god aura.

"You can't do such a simple question."

Liu Yushan is still unforgiving, but in his heart he is actually quite useful. He has been teaching and educating people for decades, and every student who comes to ask a question will only say thank you to the teacher after getting the answer, after all, in the hearts of students, teachers should know everything.

And today's Wu Bin's words reminded Liu Yushan of his experience of being a top student when he was young in school, when everyone praised him.

"Yo, Wu Bin's mouth is quite sweet, when did he work hard in English?"

The person who spoke was Chen Fang, the English class teacher, and she was also happy to see Wu Bin, a student who had been dragging the class back all the year round, suddenly want to improve.

"Work hard, I still have two tense questions I want to ask Teacher Chen later." After speaking, Wu Bin waved the English workbook in his left hand.

"Okay, wait for me here."

After Chen Fang finished speaking, the teachers in the entire office laughed.

After helping Wu Bin solve an inequality problem, Liu Yushan looked at him and asked with a little seriousness: "Do you think mathematics is difficult?" ”

"It's hard, but it's fun."

"Haha, isn't it interesting, if only you really thought so." Liu Yushan said and clicked the exercise book twice with his pen, "I have seen a lot of students who came up in the third year of high school, but your foundation is too poor, you have to spend a lot of effort, don't fish for two days and dry your nets for three days." ”

"I hope the teacher doesn't bother me."

"What teacher doesn't want to see their students motivated, as long as you are really working hard, the teacher will definitely help you."

"Thank you, teacher, I will definitely work hard!"

Liu Yushan is indeed very patient, and he answered all the questions given by Wu Bin one by one, which made Wu Bin not only understand the questions that he didn't understand during the evening self-study yesterday, but also learned a lot of new ideas for solving the problems, which can be said to have gained a lot.

"Alright, class is ten minutes away, let's go back to the classroom." Liu Yushan looked at his watch and said to Wu Bin, who was still solving the problem.

"Huh? So fast? Wu Bin looked at the clock on the wall in surprise and found that it was already half past one.

"One more question, Mr. Liu, let me do one more question." Wu Bin hurriedly pointed out a function question that he hadn't solved yet to Liu Yushan.

"You, don't think about eating a fat man in one go, it's not bad for a while."

Liu Yushan smiled when he spoke, because during the almost two-hour lunch break, he had been observing Wu Bin, originally he thought that Wu Bin would leave after asking the English questions, but he didn't expect him to continue to run back and continue to ask math problems.

And the questions asked by Wu Bin also made Liu Yushan quite satisfied, as a senior teacher, Liu Yushan heard that several of the questions raised by Wu Bin were all after his own thinking, and he couldn't do it after missing some ideas to solve the problem, instead of looking at some students who seem to like asking questions, after reading a question, he felt that he wouldn't come to ask, which was actually not good.

"Just one question, Mr. Liu, I'll leave after you finish telling me." Wu Bin made a gesture of please.

Looking at Wu Bin's appearance, Liu Yushan couldn't help but be amused, so he had to nod and say, "Okay, the last question." ”

At this time, another student in the office who also came to ask a question couldn't help but think that 10,000 grass and mud horses were running by, "This is too exaggerated." ’

Wu Bin, who finally got the solution, bowed to Liu Yushan and several other teachers and thanked him, then left the office and walked back to the classroom.

"Hey, Mr. Liu, you said that this Wu Bin can stay like this for a few days?"

After Wu Bin left, the English head teacher looked at Liu Yushan and asked.

"I think this kid can do it, his eyes can't deceive people when he does the question, he is quite devoted."

Liu Yushan's answer gave Wu Bin full affirmation.

"That's the best, but he's changed too much, isn't he stimulated by something?"

"I don't care about this, anyway, if the student wants to learn, I just teach, whether he can succeed or not, he has to rely on himself, okay, I'll go to class." After Liu Yushan finished speaking, he picked up his teaching materials and thermos cup and walked out of the office.
