After dinner, people who can afford it may go for a walk or chat to eliminate their appetite. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

But obviously, in the third year of high school, they belong to the group of people who have no conditions.

Even day students only have 30 minutes to use from the time they leave the school to the time they return to school.

For resident students, from leaving the classroom to returning to the classroom, the time is controlled within 10 minutes as fast as possible, and close to 15 minutes as slow.

After sitting down in the classroom again, one by one they silently took out their textbooks or workbooks, and then the tip of the pen kept drawing on them.

When Lin You returned to the classroom, except for a few day students, everyone else was already sitting in their seats.

He gently placed a plastic bottle of Coke on Liu Dong's desk and did not speak, and the classroom was quiet now.

"Hmm. ”

Liu Dong saw that Lin You was back, lowered his head and snorted, and continued to write in his notebook.

Lin You, who sat down, took the time to take a look at Liu Dong's notebook, which was still the physics question he had when he left.

The teacher just talked about this question, and it was not very difficult, and almost all the students in the class understood it.

Lin You looked at the scratch paper that looked very messy next to Liu Dong's right hand and didn't make a sound.

After a while, one of the girls in the class walked from her seat to the podium.

The girl is a little chubby, but she is very generous.

She took the English player out of the drawer and unplugged the student lamp plugged into the socket.

After plugging in the electricity, she adjusted it a few times, and the slightest noise sounded, which was not noticeable in the classroom.

When it was done, she said to everyone.

"Everyone, take out the English listening book!"

Hearing the words of the English study committee, everyone in the class moved.

Liu Dong had already picked up the pencil and waited steadily for the listening to be played. He noticed it when the English study committee had just gone up, and then he put the physics problem that he had been grinding on the table for a long time directly into the table.

Apparently he hadn't paid any attention to the physics problem before, and just put it on the table.

Seeing this, Lin You also took out the white English listening workbook from the drawer with the public.

"Ding Dong!"

After the player's voice sounded, the classroom was completely silent.

It's only half past five, and it's only 35 minutes before the bell rings.

......

"Everyone, turn to page 55 and take a look at this question......"

"Different topics actually have different ways of solving problems, and on this point, you need to do more questions and think more......

On the podium was a shorter man with a round face who didn't look very old.

In fact, he is only in his thirties.

Bancun's hairstyle didn't show any fierceness on him, but it looked a little cute.

This is Lin You's class teacher, surnamed Jiang, and they usually call him "Old Jiang" in private!

Although Mr. Jiang's stature is not high, his voice is very high. At the same time, the class management is also relatively strict.

So he is still quite prestigious in Class 16.

After explaining a topic, the teacher surnamed Jiang drew a new topic and prepared to start explaining.

Suddenly, he paused as he was about to begin his explanation.

"Lin You, what is this limit. ”

There are no questions such as "Who will do this?" or "Who made this problem?" Teachers in the third year of high school basically don't do these time-wasting things.

directly pulled Lin You out.

Teacher Jiang refers to a math problem, the kind that seeks the limit. This kind of problem is very common in high school mathematics and is not considered a rare topic.

But this question is very difficult for students outside the first three rows of the class.

Lin You looked at his relatively clean scratch paper, which only had a few traces of brushstrokes, which was completely incomparable to the scratch paper that Liu Dong was full of paintings at the same table.

Lin You stood up, paused, and after hesitating, he replied directly and decisively.

"No, it won't. ”

The teacher surnamed Jiang heard Lin You's answer, and his fingers facing the blackboard who were writing paused slightly.

After writing a line of formulas, he threw the blackboard eraser in his left hand onto the podium and said "pop!" to the class.

"As a science student, how can you not use your pen?"

"Don't sit there shaking your head like a liberal arts student, is it good to read and memorize math?"

A harsh criticism was unleashed at the students.

When the teacher surnamed Jiang said this, his eyes were staring at Lin You.

After looking at him for two seconds, Lin You hesitated and slowly lowered his head.

"Everyone has to work hard, the first round of revision is crucial. At this stage, there will be many students' grades suddenly raised, and some students should not slack off!"

Liu Dong, who was on Lin You's side, listened to Teacher Jiang's words, his eyes kept scanning the surroundings, and he focused on Lin You and Teacher Jiang for a few moments, looking a little excited.

Obviously, he thinks that the person whose grades will improve in Mr. Jiang's words refers to himself, and the one who is slacking off and has obviously declined in his grades refers to Lin You next to him.

"It's not possible, most likely I won't be at the same table with Lin You next time......" Liu Dong muttered in his heart.

Just as Mr. Jiang was about to explain this topic, the bell rang for the end of the evening self-study, so he gave up.

He waved his hand to his classmates and walked out of the classroom with his hands behind his back.

The bell rang for the end of class, and the atmosphere in the class suddenly became a little lively.

The evening self-study period is longer than that of the daytime, and both teachers and students need to order a break between classes.

The teacher will use about 10 minutes to sit in the office and drink tea.

Students will rush to solve their metabolic needs, or quickly ask for help from their classmates to try to understand what the teacher is talking about in class.

"Lin You, this question is very simple, in fact, the idea is like this......"

Lin You sat down directly after Teacher Jiang walked out of the classroom, and he looked at his scratch paper. When Liu Dong next to him made a sound, Lin You was obviously a little stunned.

Seeing that Liu Dong was very enthusiastic, Lin You mumbled vaguely.

"Then I'll teach you!" Liu Dong looked a little happy when he heard Lin You agree. He deliberately amplified his voice, startling the girl who was lying on the table behind the two of them.

The girl raised her head, glanced at Liu Dong, her face showed no expression, and then continued to lower her head and do her homework.

Liu Dong saw the girl at the back table raise his head and look at him, and he was a little happy in his heart, but he didn't look at the back, but continued to talk to Lin You with his head sideways.

Liu Dong's gaze was focused, he picked up the black carbon pen, placed it on his crumpled scratch paper, and pushed his glasses.

However, he found that his scratch paper was very messy, and there was no extra space for him to splash ink.

So he was ready to reach out and take Lin You's scratch paper over and write it.

But to his surprise, he was one step late.

"I said, Xiaoyou, how can you ignore the teacher in class!"

"You can't be lazy like this!"

In the front row of the classroom, a male student walked in, his short hair and smiling ruffian, but not annoying. It was he who took Lin You's scratch paper.

Obviously, he didn't believe that Lin You would not be able to do that simple math problem, although this simplicity was relative. So when he stretched out his hand, he said the above two sentences to Lin You.

"Get out of here! ”

Lin You heard his words and said with a smile.

The other party heard Lin You's joke, shrugged his shoulders, and then looked at Lin You's scratch paper.

Sure enough, he saw the correct answer on Lin You's paper, and then he glanced at Liu Dong, who was a little frozen there.

looked at Lin You, smiled, and said, "You are really lazy, no wonder you say no, the process is written like this!"

As we all know, the mathematics of the college entrance examination has a process score. Even if you solve the problem, if you only lose one answer there, you will probably only end up with one or two points.

And this is exactly what Mr. Jiang has emphasized every class since entering the third year of high school, and at the same time, every class has also been trained.

He asked the students to write the process and put it on the paper even if they didn't know the correct answer. That might be another three or four points. Of course, this is for word problems and so on.

In this regard, Lin You smiled helplessly.

Previously, his grades had dropped because of a special experience. Maybe it was because of the memories of more than twenty years suddenly crammed into his brain, causing his mind to be dizzy.

For the first few days, he was in a daze, feeling like he was in a dream.

After that, it got a little better, but it also caused him to have a vague sense of memory of his two lives. This feeling is like a person's memory of his childhood, he knows it, but it is not clear.

So, after losing at the end of his sophomore year, he slipped from the front row of the classroom to the middle. The same table was changed from Wang Xiale to Liu Dong.

However, even if he has a sense of alienation from those mathematical knowledge, he is not short of such things as problem-solving ideas, after all, in another life, there will always be something to gain from brushing problems for a year.

And this kind of problem of finding the limit, the difficulty lies in the idea of solving the problem.

With the right idea, you can write out the process and the correct answer in less than two minutes.

If the idea reaches a dead end, two hours of grinding will not lead to results.

Wang Xiale looked at Lin You's scratch paper, looked at it, and his eyes widened.

He said to Lin You, "What did you do here?"

Wang Xiale's tone was strange, full of disbelief and incomprehension. His voice was a bit loud.

Not only Liu Dong on the side was attracted by Wang Xiale's tone, but the surrounding classmates also attracted attention.

The female classmate who was still lying on the table behind Lin You also raised her head. She looked at Wang Xiale curiously, and then looked at Lin You.

"Lao Liu! Lao Liu, come and see!" Wang Xiale called to the first row of the classroom.

This old Liu is not the old Liu.

Lao Liu, who sat in the first row, was a ruthless person who sat firmly in the position of the top student in the class. A pair of large glasses framed against the bridge of his nose, the yellow tortoiseshell and his yellowish pupils contrasted with each other, which was very much in line with people's understanding of the creature of Xueba.

But Lao Liu's personality is not dull, but very cheerful and playful. has a good relationship with Wang Xiale and Lin You.

When Lao Liu heard this, he threw the pen in his hand directly on the table, and then walked towards Lin You.

Lin You already knew what was happening here, although he couldn't get used to Liu Dong's somewhat embarrassed performance, but before and after seeing Wang Xiale on the board, he continued to do his own questions in his seat.

At this time, when he heard Wang Xiale call him, he came over directly. Although he was also a little confused about Wang Xiale's performance.

"Look, look! Is this the formula you told me the other day when you were pretending?"

When Lao Liu heard this, he took the scratch paper, put it on Lin You's table, lowered his eyes, and looked at it carefully.

When Liu Dong heard this, he also looked at the scratch paper. See the above multiple letter expressions, arranged in multiplication or division.

"It's kind of like a derivative formula...... It's a bit ......."

Liu Dong couldn't understand and didn't make a sound.

"Ahem!" Lao Liu glanced at it a few times, coughed lightly, and looked at Lin You.

"Lopida's Law!"

"Boss, you've really learned high math!"

Lao Liu directly grabbed Lin You's right hand and called exaggeratedly.

Of course, high mathematics is not high school mathematics, it is advanced mathematics, which is only learned in college.

When chatting before, they said that they would learn advanced mathematics to increase some problem-solving skills and ideas. But now that they have just entered their third year of high school, Lao Liu and Wang Xiale have not read much high math books.

When Lao Liu grabbed his right hand, the corners of Lin You's mouth twitched.

Seeing Lin You's strange expression, Lao Liu thought that he was a little speechless about his performance, and laughed a few times.

"What are you laughing at, let go of your dog's paws, don't you see that Brother You's right hand is injured?"

Wang Xiale, who was standing beside Lao Liu, slapped Lao Liu's hand angrily.

Hearing this, Lao Liu let go of Lin You's right arm and laughed dryly a few more times.

It turned out that he happened to grab the bruise on Lin You's arm.

Seeing that Liu Lao finally let go of his hand, Lin You couldn't help but breathe a sigh of relief.

After being hit by a dumbbell, his right arm and right hand were very weak. Although it was much better than at noon, I still couldn't hold the pen a little, and when I was caught, it hurt a lot.

So, he solved that problem with a rule he learned in college. It's easy and fast, and you don't need to type a lot of drafts.

However, it is obvious that this solution does not meet Lao Jiang's requirements.

So he directly said to Mr. Jiang that he wouldn't.

At this time, Liu Dong on the side also relieved himself.

He felt his face flush a little.

I think that others can't, and I want to teach others. How do you know that people will know, but they have to say that they won't.

And the reason for this is that the problem solving method is too high, and the process of solving the problem is also cold, with only a few letters.

Seeing that the people around them looked over in surprise, the two female classmates behind them also looked at them with interest.

Liu Dong's lips twitched a few times and spoke.

"In this way, if you write it like this in the college entrance examination, you won't get many points......

Lin You heard Liu Dong beside him say a little unconfidently, and turned his head to look at him.

That's right, because writing like this will probably not get Lao Jiang's approval, so he didn't say it.

When the onlookers heard this, they also discussed.

Since this method is not recognized in the college entrance examination, it has little value.

It seems that today is just a little farce.

Some of the people around me thought so. For the students of Class 16, who have a strong learning atmosphere, if they don't see that they may be able to learn something from Lin You, they will not waste their precious recess time to watch.

Liu Dong saw that everyone was agreeing with each other, and he also seemed very confident. Then he pretended to be casual and said to Lin You.

"I'm right...... ......."

"yes, yes!"

"Have you read the original paper of the college entrance examination?

"Does this kind of extreme question in the college entrance examination need to be written? It mostly appears in multiple-choice questions and fill-in-the-blank questions. ”

"Even if there are short-answer questions or application questions, it's just a small link, and you don't need to write it clearly at all!"

Before Liu Dong's words were finished, Lao Liu crackled at him and said a large string, making him have to hold the words in his mouth as a last resort, and spit them out without a face.

"However, maybe you know the answer, but you still can't reverse the process......

At this time, Wang Xiale made up for the last knife.

The eyes of the people around him who said these words lit up.

"Oh yes, there's no need for a process, it's a lot of time saver!"

"Knowing the answer through this method, it is very simple to reverse the deduction, after all, it is difficult to think of ideas!"

"It's very suitable for the college entrance examination!"

Seeing this scene, the pen in Liu Dong's hand fell to the ground with a snap, and he didn't pick it up. Liu Dong lowered his head and looked at Lin You's scratch paper, staring at the formulas motionlessly.
