Chapter 18 Knowledge

The teacher was lecturing all the time. Wu Tong paid some attention and listened attentively. Meanwhile, her subordinates were slowly deducing on the draft paper the Lagrange mean value theorem that she had just come across.

Assume F(x) = ······. Since F(x) is continuous on the closed interval (a, b) and differentiable in (a, b), therefore F(x) is continuous on the closed interval (a, b) and differentiable in (a, b)·····

The above proof is in a b, then the function f(x) is continuous on the closed interval [a, b] and differentiable on the open interval (a, b). Then there is at least one point ξ in the open interval (a, b) such that f'(ξ)=(f(b)-f(a))/(ba)···

She is now more in tune with the Enlightenment Stele and no longer needs to connect with it specially. As long as she calms down, she can immediately enter a state of deep learning with no distractions anytime and anywhere. She can enter and interrupt at any time, very easily.

When Wu Tong heard her teacher calling her, she was stunned for a moment before she reacted, put down her pen and stood up.

"teacher."

At the staircase, teachers and students gathered and walked towards the teacher's office at the end of the corridor. The teacher's office for the second grade was at the eastern end of their floor, which meant that the classrooms on their floor were basically under the teachers' eyes, so the discipline was pretty good.

Chen Qiu Sheng looked at Wu Tong from the side. He didn't know when the girl straightened her back, her eyebrows and eyes were delicate, as if the dust had been washed away by pearls, and she was radiant and smooth, completely different from the inconspicuous girl in the past.

"You did very well in the exam this time. Did you study hard during the summer vacation?" Chen Qiu Sheng started.

"Yes, Mr. Chen, I feel that my foundation is not solid, so I re-took six science courses during the summer vacation!"

"It's a good thing that you can wake up to this and learn to study hard. The teacher is very happy. Congratulations on getting the first place in the grade in this baseline test!" This was beyond the teacher's expectations. However, Chen Qiusheng has been a teacher for many years and has put away his complicated emotions. Now when facing students, he still smiles and softens his usual seriousness.

No matter what, it is a happy thing if students do well in exams.

"I was ignorant before and caused the teacher a lot of worry." Wu Tong apologized to the teacher for her previous willfulness. When she didn't study hard, the teacher talked to her many times and worried about her. She was a very good teacher.

"It's what the teacher should do!" Chen Qiusheng was straightforward and not used to beating around the bush. He went straight to the point: "According to your results this time, you can be promoted to the top class one or two. As you know, the top class in our school gathers the best teachers in the school, which is better for you. The teacher of the top class also welcomes you to transfer to the class. I will talk to you in the next two days."

"Go home today and discuss with your family to see how to arrange for a class transfer. The teacher respects your opinion!"

Elite class? That was the place she had dreamed of entering back then, and she had thought about it. However, times had changed, and she was no longer obsessed with the elite class.

"Teacher Chen, rather than changing classes, I would rather skip a grade and take the college entrance exam in advance. If I can't skip a grade, I might try to take the route of competition recommendation!" Wu Tong pondered for a moment and expressed her thoughts. This idea came into her mind after she mastered all the high school subjects.

She went to school for the purpose of acquiring knowledge, and she had no vain idea of ​​reliving her youthful high school life again. After fully mastering high school knowledge, there was no need to waste another year in high school. Education and book resources in a small county are scarce after all. Entering university a year earlier will also allow her to be exposed to a wider range of knowledge. As long as her heart is there, there is no place that is not the prime of youth.

Therefore, after she made up her mind, she also made two alternative routes for herself, which she could carry out simultaneously to prepare for both situations. To Wu Tong, to be honest, the competition was an unfamiliar area. It was a game for geniuses, which was too far away from her before. She had just started to learn about it and needed to strengthen her training. She could not use it as a life-saving straw, but just as an alternative.

For her, the safest route is to take the college entrance examination early, and she will work hard with the school to get it.

"Skip a grade?" Chen Qiu Sheng was a little surprised. Why did he come up with such an idea?

Even though Wu Tong got a near-perfect score in this test, it was just a basic test after all! Most of the questions tested were only about the knowledge of the first year of high school, but based on this, you can't think that the college entrance examination is that easy!

"Yes, Teacher Chen, I am not complacent just because my test results were OK!" Wu Tong's expression was serious and solemn. "I have completed all six science subjects in high school by myself. Regarding this point, the teacher can test me at will, and I can accept it."

Whether she can take the college entrance examination in advance depends on the teacher's communication with the school leaders. She must first convince Teacher Chen. And the best way to convince her is to let the teacher verify her current level with his own eyes.

Have you finished all the courses? Are you sure you didn't just go through all the high school textbooks?

Chen Qiusheng looked at his watch. It was the beginning of the morning self-study session. "I heard that you always hand in your paper half the time in advance in the exam room?"

"I can't even submit the Chinese test in half the time!" Wu Tong smiled and nodded, but she didn't say too confidently. She still needed to practice more and accumulate more knowledge in Chinese.

Wu Tong was quite helpless about the fact that her previous advantage subject had now become her weakest point. However, Chinese language really needed time to accumulate, and she couldn't just do it overnight!

"Come on, I'll find you a test paper. Try it out and see if it's a mule or a horse. Let's pull it out for a walk!" Chen Qiusheng wanted to really get a feel for the students, so he took a math test paper from the third grade and said, "Come on, Wu Tong, are you sure you have finished studying the high school math textbook?"

"Yes, Teacher Chen!" Wu Tong nodded confidently.

"Come on, do this test paper and let the teacher see your level!"

After half an hour, when Wu Tong finished the paper, he checked the answers and confirmed that he had got full marks again. Chen Qiu Sheng really felt that he had learned a lot!

There is a famous saying that genius is 1% inspiration and 99% perspiration. He has been teaching for many years, and even if there are occasional outstanding students, it is basically the 99% perspiration that makes good grades. He has also seen children who were not serious about studying at first, but later paid attention and their grades jumped up and they were admitted to good universities.

But this student in front of him, only took two months of retaking the course during the summer vacation, but he made a huge leap to full marks. He also completed the high school content by self-study and truly mastered the high school content. This really made him see what extraordinary talent is.
