Before returning to the college entrance examination, I became popular in the science circle

ring ring ring...

The bell rang for the end of the night self-study get out of class. There was no special arrangement for the training class time. It was also based on the time of the night self-study class.From 06:30 to nine o'clock, it is exactly two and a half hours.

Duan Hong was patrolling the field and took a look when he walked to Wu Tong's desk. Wu Tong had already turned a page and was doing question No. [-]. There were densely written drafts of the deduction formula process, which were stacked on the corner of the table. Nearly a knuckle thick.

In other words, in the one and a half hours since he gave Wu Tong these papers, she had already done six more questions while the others in the class were still struggling with the provincial competition questions just now. The difficult national competition questions, the speed and the gap made him tremble again!

He didn't know what geniuses in other provinces and cities were like, but this student named Wu Tong gave him the extravagant hope of the national competition, and even the ambition of the national team.

When the bell rang, Duan Hong directly announced that the time was up. When it was time to collect the papers, very few in the class had completed four questions.In the past, he might have been so disappointed that he was so angry, but today because of Wu Tong, Duan Hong rarely said anything, collected the papers and sent them home after class.

This group of people didn't live up to expectations today, and the impact of Wu Tong's impact was enough.

Sun Chao ended his entanglement in thinking. Although he did the last question, he felt that the direction might be wrong.He turned back to Wu Tong, "Boss, how did you do the last question?"

Wu Tong paused to clean up. The title "big boss" made her a little weird!However, Wu Tong was not a fussy person. He took out the piece of paper he had just picked up and said, "This is my idea. Take a look!"

"Definition set A=..., where N is a set of positive integers,... Since a is an infinite set, the elements in A are now arranged into an infinite sequence in order from small to large...Determine n and m, The relationship of k,... therefore satisfied, the condition is established!"

"Thank you!" The big brother's ideas and the deduction process on the draft paper are very clear. If there is something that can't be understood, Sun Chao feels that he can retire directly.

Waving his hand to indicate that Sun Chao was welcome, Wu Tong packed his bag and left the teaching and research office directly.She is not very good at active communication. Her first action after class is to pack her schoolbag and go home.Now that Teacher Duan has given me these questions, I can even save the step of going back to the classroom!

The others were a little slower and missed the student who made friends with Wu Tong, and the few who approached couldn't help but angrily took pictures of Sun Chao who took the lead.

"Old Sun, it's not kind of you to enjoy the boss's advice all to yourself!" It was this dog thief who misunderstood them, and they also want to be instructed by the master, okay!If they didn't think there would be another chance in the future, they really wanted to drag this thief who had taken the lead!

As everyone knows, Wu Tong has already obtained permission from Duan Hong to let her slowly study the national competition questions in her hand, at her own pace, without having to follow the big class.

The next few lessons are mainly used to talk about today's papers. Wu Tong has already passed with full marks, so why waste Wu Tong's time?This student is very good at self-learning ability and self-discipline, and she will earn more if she arranges it by herself!

That is to say, Wu Tong does not need to take the next [-] Mathematical Olympiad training class. Wu Tong officially witnessed the questions of Mathematical Olympiad, but they are more difficult questions. The training of Mathematical Olympiad class does not have specific thinking. That's all!

Until the exam, this group of people had the opportunity to meet Wu Tong, which almost made this group feel sorry, and was so angry that after they found out that Wu Tong didn't have to come to class on Thursday, they settled the bill with Sun Chao again. Wu Tong can now know the follow-up!

"Tongtong, here!" Wu Jingzhong was guarding in front of the school gate, and when he saw his daughter coming out, he immediately greeted her with a smile on his face, took the bookbag in Wu Tong's hand, and stuffed Wu Tong with a warm pancake: "Are you hungry? Quick Pad Pad, I just made it, and I added more crispy ones!"

Since Wu Tong's night self-study in junior high school, as long as Wu Jingzhong is at home, he will come to pick up Wu Tong in person at night, rain or shine.The road to their house is a big road, not too dark, but Wu Jingzhong is still worried that the child will go home by self-study next night.

"It smells so good, Comrade Wu. I give you a thumbs up. I'm hungry!" She continued to do difficult questions for two and a half hours. Her brain's CPU was running continuously, which really consumed a lot. Now she could smell the cake. The aroma instantly aroused hunger.Wu Tong brought the cake to his mouth and took a big bite. This was the taste.

Teacher Jin gave her little food from the stall, and when Comrade Wu picked her up, he would quietly feed her from time to time.Comrade Wu is riding a bicycle, Wu Tong is sitting in the back seat, leaning on his father's back, holding Comrade Wu's clothes in one hand, and eating cakes in the other, nothing is more happy than this!

"Generally, in a process of change, assuming that there are two variables x, y,...the independent variable and the dependent variable...then it is a proportional function!..."

After finishing the summary of a large chapter on functions, Wu Tong paused, turned his head and asked: "Brother, do you understand?"

In the past few days, Wu Tong has allocated time for self-study of advanced mathematics and problem-solving at school, and will go to Jin's house to talk to Jin Xin at noon.

It took two days for Jinxin to sort out the logic of sets, subsets, unions, intersections, and complements from the set, and after Jinxin mastered it, he started to carry out these two days function combing.

"I understand!" Jin Xin's eyes were filled with sudden realization.

The broken links of incomprehension and knowledge that Wu Tong had sorted out and filled in before were now merged into a long chain of complete understanding. Jin Xin felt that it was now clearer.

His admiration for his sister is like the water of the Yellow River. Tongtong has all kinds of knowledge at his fingertips. He writes and lists them casually. It is a detailed derivation of formulas, which is like playing with mathematics.Where does he get stuck, whether it's speaking straight or backwards, Tongtong can break apart the knowledge and break it into pieces for him to understand.

At this moment, he only felt that the pen under his hand was about to move, and wanted to turn into a 40-meter sword, cut towards the mountain of books and the sea of ​​questions, and solve all the problems.

Ha... OK, Wu Tong didn't want to dampen Jin Xin's enthusiasm. He raised his hand and handed a stack of papers prepared in advance to Jin Xin, "Then let's do these!"

The little brother’s current state is that he feels that he has mastered all of them. After brushing through the papers that she carefully selected, and then going through the tempering of the quiz in the senior three exams, compressing all the moisture, he has truly mastered the high school set and functions. this one.

The effect of her tutoring for my little brother should be reflected in the results of the high school exam in March tomorrow and the results next week.

"Tomorrow's exam, little brother, come on!" Wu Tong stretched out his hand and clenched his fist, and fisted with Jin Xin's buddies, smiling and encouraging.

"Give me five, it's necessary!" Jin Xin nodded vigorously, otherwise he would be sorry for Tong Tong's hard work!
