The system development of a scholar

Chapter 7 I Will Know This Question
After finally falling asleep, it didn't take long for the alarm to ring.

After getting up and washing his face with cold water, Xu You left the bathroom and went downstairs to school after the sleepiness subsided.

The first class in the afternoon was physics. When Xu You walked into the classroom, he found that the physics teacher Yang Shouyu was already standing on the podium.

"Why are you here so early..."

After coming to his seat and sitting down, he looked at the time and saw that there were still 10 minutes before the class. Xu You took out the physics paper. The teacher said last week that this class will be about the paper.

While waiting for class, Xu You memorized the knowledge points he recorded on the paper when he corrected his mistakes.

"Take out the paper." When the class bell rang, Yang Shouyu put Liu Yu's newly bought physics materials back, looked at the students and said, "Let me see how your self-consciousness is. You didn't even read the paper when you went back." Waiting for everyone to put the paper Putting it on the table, Yang Shouyu stepped down from the podium and checked it.

Walking in front of Xu You, Yang Shouyu paused for a while, glanced over his paper, and then showed a hint of surprise on his face.

The questions on the paper, whether right or wrong, each question is marked with the knowledge points of the investigation in red pen, and the wrong questions are also corrected. The handwriting is clear and the format is rigorous.

It's better than what Ye Jin did...

Nodding his head slightly, showing a satisfied expression, Yang Shouyu walked up to the podium without saying anything, and said with a wry smile: "There are more than forty students in the class, and only five students corrected their mistakes. You are really big-hearted."

Lowering his head and taking out the paper he had prepared, Yang Shouyu raised his head and said, "The first multiple-choice question is the description of motion, and you will be given a sub-question, choose B; the second question is the law and application of linear motion with constant speed."

He picked up the chalk and turned around to write on the blackboard: "First define the positive direction of the speed, according to the formula x=vt+1/2at^2, get two times, one is 3s, the other is 5s, according to the meaning of the question, 5s If it doesn't match, discard it, so choose A..."

Although Xu You knew how to do it, he listened carefully and sorted out the ideas for solving the problem one more time to consolidate his knowledge...

Mr. Yang is very fast in terms of both the speed of lectures and the speed of lecturing questions. In less than half a class, the two items of choice and filling in the blanks have been finished, and it is time to answer the questions at the end.

"You all say that answering the questions is difficult. It's because you didn't read the questions carefully, Ma Daha, and couldn't grasp the hidden hints given by the question stems, so it took time and effort to do it. Take this question as an example. If you find the stem of the question The hidden hints in the game are very simple to solve, similar to sending points."

He took the paper and said: "Take this question as an example. If you follow the general problem-solving method, it is very troublesome and cumbersome, but you just need to grasp the word 'slide over' in the stem of the question and realize that it does not Friction, it only takes three steps to solve the problem, and the answer can be solved..."

"Is there such an operation?!"

Looking at the problem-solving steps written by Lao Yang on the blackboard, Xu You felt that the two of them were doing two different problems.

When I was doing this problem, I first listed the known conditions, and then wrote out the required problem-solving formula, and finally calculated the unknown quantities in the formula step by step, and slowly substituted...

But Lao Yang only wrote "Because..." before solving the problem, omitting many steps, and found the answer very concisely.

"This is the difference between bronze and king operation..."

Looking at the process of solving the problem that he wrote in the blank space, Xu You was deeply moved, the operation of the king is just arrogance...

"There are 5 minutes left to finish class, and the last real exam question for the college entrance examination will definitely not be finished. Do you still want to talk about it?" Yang Shouyu asked with a smile after glancing at the time.

"Speak~"

For the teacher's question that you can't refuse, the students answered very perfunctorily, with the attitude that you are happy.

"Forget it, this kind of question combining mechanics and electricity has always been a popular question for the finale of the college entrance examination physics. The calculation is complicated, and it can't be explained clearly in more than ten minutes. Let's wait until the next class."

Yang Shouyu closed the paper, looked at the tired students, and said with a smile, "I won't assign any other homework today. I'll go back and digest this paper, and then try to do the last question."

"It's hard enough to test mechanics and electricity alone, how about combining the two? The person who wrote the test is going to heaven!"

Xu You read the last question when he corrected his mistakes, and analyzed it carefully. He used a few pages of drafts to calculate according to the known conditions, but every time he couldn't match the answer, he gave up when there was nothing he could do.

"Looks like I'm going to get liver late again tonight..."

Although I really want to redeem a section of [Tutorial on Important and Difficult Knowledge] to kill this question in seconds, but I don’t have enough points, so I can only go back and drink a few more bowls of my mother’s brain-boosting porridge.

After a short break after class, Ma Jian walked in with the papers in hand. As soon as the class bell rang, it was another lecture class...

In fact, compared to physics, Xu You thinks that chemistry is more difficult, especially deriving chemical reaction equations based on some chemical reactions, or deriving equations based on residual element ions, is very brain-intensive.

Since most of the questions on the paper are familiar, Xu You listened to this class very comfortably. Even for the two wrong questions, after a little guidance from Ma Jian, he suddenly understood why he was wrong and the correct way to do it. What is it again.

The penultimate class is Biology.

The biology teacher is a young female teacher named Liu Yong, who is Ma Jian's younger sister.

Liu Yong, who was dressed in a dark blue long dress, walked up to the podium, opened the book and said, "We will teach this class, not the papers, and we will talk about it tomorrow..."

Today, the teachers of other subjects were teaching the papers. She was afraid that the students would be bored, so she not only postponed the lectures that were originally planned, but also did not open a new chapter. She just summed up the knowledge of this chapter.

In the first year of high school, biology was relatively simple, and there were too many things to memorize, but once in the second year of high school, after the division of arts and sciences, the difficulty began to increase, especially as it progressed, it became more difficult.

Fortunately, Xu You had a good foundation in biology in his freshman year of high school. Even though he lost interest in studying last semester and had the idea of ​​giving up on himself, he didn't feel relieved in biology, so his biology was still good.

After reviewing it with the teacher, some slightly vague knowledge points became clear immediately, and the problems that were not understood thoroughly were also understood. Generally speaking, this class has gained a lot.

In the last self-study class, Xu You began to write the homework assigned by the teachers of each subject.

There is no teacher in the self-study class, so Liu Shen stopped reading novels, and chatted with Li Zhen in the front row about a new way of playing jungle that he learned online recently.

Li Zhen went to the Internet cafe at noon and lost both games, so she and Liu Shen spat about those unskilled and unconscious teammates, and they chatted intensely for a while.

Although Liu Shen's game skills are not very good, he is an excellent troll. Because of a game, Zeng Jin wanted to call his teammates. The two scolded each other for a week, and they were regarded as legends.

"Hey, Xu You, when will you have time to bring your brothers?" Recently, without Xu You, the great master, Liu Shen's rank has fallen precipitously, and he has knelt for seven games in a row.

"I don't have time recently, wait for the holiday."

He has to solve 200 questions in five days, how can he have time to play games, even if he has, he doesn't want to play, it's boring...

Seeing that Xu You, who wrote the question, didn't even lift his head, Liu Shen cut his head and continued to exchange game experience with Li Zhen in a low voice.

Xu You, who was completely immersed in the sea of ​​questions, was not affected by them, and his ears automatically blocked their voices.

During evening self-study, Xu You walked into the classroom with a stack of papers, which immediately attracted Liu Yu's attention.

"Fuck, so many papers? Are you crazy!"

Stopping Xu You from taking a look at the papers in his hand, Liu Yu was shocked. There are five books in mathematics, physics, chemistry, biology, and English!

"Do you want to study hard?"

Taking back the paper and smiling, under the surprised eyes of his classmates, Xu You returned to his seat and sat down, and continued to write the paper that was not finished in the self-study class.

Wang Ya, who was writing the questions in the front row with her head down, raised her head at this time. There was a question she didn't know, and she planned to ask Ye Shen, but found that Ye Shen was explaining the question to someone else.

Unwilling to ask others for advice, she planned to wait, but she caught sight of Xu You out of the corner of her eye, and a small thought popped out of her mind.

"Should I ask him?"

The corner of her mouth was raised, Wang Ya turned around, and said to Xu You who was thinking with his head down, "Xu You, I have a question that I can't understand, can you help me look at it?"

Since he had just sat down, Xu You hadn't yet entered that immersive learning state. When he heard Wang Ya's words, he raised his head and was taken aback for a moment. Why did she suddenly think of asking me a question?She studies better than me.

Although puzzled, he still asked, "What question?"

Wang Ya smiled and handed the information book in her hand to Xu You, "This question is quite difficult."

For this math problem, Xu You looked at the problem, sorted out his thoughts in his mind a little bit, and said, "I can do this problem."
