Rekindle 2003

Chapter 18 Can everything be Lobita?
"Your English teacher is still grading papers intensively. This class will be changed to physics."

What the physics teacher Wang Jianjun said stunned Lin Xun and Wang Zihao.

Got it!
We have to wait for the face-slapping part.

The two sat listlessly on their seats.

They are not looking forward to slapping Qingyun in the face now.

Feeling a bit dull.

Who are you slapping in the face for?
Tang Qianying was a little sleepy.

After two classes in a row, and one of the most brain-intensive math classes, there was no break between classes, her brain was on strike.

Covered by the tall books piled up on the desk, she stretched, "I'm so sleepy today!"

A standard stretching exercise makes the curves in front of you fully visible.

Seeing this, Qin Manman rolled his eyes, leaned sideways on the table, and echoed, "I'm a little sleepy too."

Qing Yun, whose sight was blocked by the back of her head, sighed inwardly, buried her head and began to carry the creature on her back.

See what's wrong?
You won't lose your position as a 'big wife'.

This woman is good at everything, but she is a little stingy!
Tang Qianying took out a bottle of essential oil and dripped it on her face, "I need to wake up quickly, it's physics class."

She had planned to relax in this English class.

English is her strong point, and she has never scored lower than 145 since she was in high school.

Qin Manman asked her to ask her to drip the essence of wind oil on the toilet paper and put it aside, "It's just right to take some simple subjects when you are unconscious."

Guan Xiaohe in the front row turned her head angrily, "Manman! I think you are itchy today!"

Yang Yue next to her covered her mouth and smiled, "You haven't noticed yet? It's a female competition today!

A mother with a high IQ can give birth to a child with a high IQ, you say so, Qing Yun. "

Qin Manman suddenly became furious, kicking the chairs of two unscrupulous girlfriends with his long legs underneath.

Tang Qianying's expression froze when she heard the words. She looked at Qin Manman, who was making a fuss, and was puzzled.

Did she see it?
She sees it!
A pair of manga eyes narrowed.

Hello, Qin Manman!

I didn't say I wanted to rob you, so I put it here to play dirty tricks for my sister, right?

Believe it or not...

Tang Qianying's shoulders suddenly collapsed again.

Forget it.

If you get along with each other, you will be able to prevent it if you change to yourself.

Girlfriend.

The reason why best friends become best friends is because of the saying: "Things of a kind gather together and people are divided into groups".

Girlfriends have similar interests, appreciation levels, and looks, as well as temperament, disposition, and behavior, etc., otherwise they wouldn't be girlfriends.

When both parties are similar to each other in every way, what you like may be what she likes.

The reverse is also true, so men tend to fall in love with girlfriends' girlfriends.

Tang Qianying sighed inwardly, and lowered her head with a complicated expression.

Well, Manman, I admit, you were right.

I do like him.

However, Qin Manman...

Can you really go on with him for a long time?

We are best girlfriends, do you think I don't understand your thoughts?

"Students, the test papers for the second diagnosis are still being corrected. Have you done all the after-school questions assigned last time?"

Wang Jianjun stood on the podium and started flipping through the paper in his hand.

"Damn it! I forgot!"

Tang Qianying immediately woke up, and she didn't move a single word of the homework assigned before the second exam.

"Sister Ying, I have good news and bad news. The good news is that I didn't do it either." Zhou Li, who was diagonally ahead, turned her head and smiled at her.

"What about the bad news?" Tang Qianying felt a little more at ease when she heard that the study committee hadn't done anything.

Zhou Li giggled, "The bad news is that I can finish it in 3 minutes."

Tang Qianying was speechless.

This bunch of girlfriends are together to bully me today, right?

"Qin Manman, tell me about this question."

Seeing some commotion in the back row, Wang Jianjun simply named Qin Manman, the center of the commotion.

Qin Manman quickly retracted his legs and stood up holding the question sheet, "As shown in the picture, a long enough horizontal conveyor belt always moves to the left at a speed of v=3m/s..."

Wang Jianjun frowned and interrupted her, "Qin Manman, what are you doing reading the questions?"

Qin Manman looked at the question list, "Mr. Wang, because the class has just started, I think the students need a little time to focus on the class. So I will read it with the questions."

Wang Jianjun nodded with a smile, he deserves to be number one in his grade!

Doing things is so thoughtful!

That boy Qingyun is really cheap.

Not to mention, the two of them are a good match when they walk together.

Qing Yun is his favorite student, so naturally he is pleasing to the eye no matter how he sees it.

However, it's kind of weird.

Why does this silly boy look at his own wife like this?
At this moment, Qing Yun was stunned as he looked at the blank questionnaire in Qin Manman's hand beside him.

My wife doesn't seem to be so honest!
Read the questions because she needs time to do mental calculations.

"The first small question is the common speed of the ball and the wooden box at the moment of meeting. Let us assume that the first ball and the wooden box are moving together at the moment of v1. According to the law of conservation of momentum, after substituting the data, the answer is 1m /s.

The second small question examines the displacement, we assume that the distance between the point where the first ball meets the wooden box and the left end of the conveyor belt is S..."

Wang Jianjun applauded, "The train of thought and answer to this question are both correct. Qin Manman spoke very well."

Just when Qin Manman was about to sit down after smiling reservedly, Wang Jianjun added, "Just remember to do your homework next time."

The classroom suddenly burst into laughter, and Qin Manman also blushed, sitting there embarrassed.

"In today's class, we will do the finale of the Jiangsu volume in the first half of the class, and we will comment on the second half of the class."

After Wang Jianjun asked everyone to start doing the questions, he asked Qingyun to do other subjects like Li Fangping.

This kind of treatment made Qin Manman a little envious.

For physics, she couldn't get full marks, so naturally she had to do the questions honestly.

Wang Jianjun also left the classroom. He had just finished reading the test paper and hadn't had time to go to the bathroom yet.

Qing Yun in the classroom felt a little helpless.

After nearly two hours of liberal arts subjects, his mind was a little numb.

Qin Manman also knew about this situation and asked him to rest.

After quickly solving the first small question, Tang Qianying began to routinely stare blankly at the last two questions of the finale.

She was sure that this was a topic she couldn't afford.

Just now Yang Yue's "female competition" remarks came to mind again.

She snorted coldly.

OK!

It seems that in the math class, his anxious performance for Qingyun fell into the eyes of caring people, and he was considered an early bird.

She glared at Qing Yun angrily, but unexpectedly the two of them met directly across Qin Manman's back.

Qing Yun grinned at her, "Show me your math paper, I'm about to fall asleep."

Tang Qianying didn't want to talk to him at all.

But when she thought of the word 'female competition', she felt a burst of fire in her heart, and handed over the paper in a strange way, "Why is it my paper?"

Qing Yun took the paper and said sincerely, "I really like studying your problem-solving ideas."

Tang Qianying, Qin Manman in the middle, and the few people who were eavesdropping were all dazed.

Tang Qianying's mathematics, what ideas can I have for solving problems?

"Your thinking makes me feel bright, and it is a problem-solving method that I can't think of."

Tang Qianying:? ? ?

Qin Manman:? ? ?

Chen Yue:? ? ?
The faces of the people who eat melons are collectively filled with question marks.

"Every time I will solve the problem according to your problem-solving ideas, but I can't solve it every time."

Qing Yun's words made everyone laugh uncontrollably.

Fortunately, it is a classroom, even though the teacher is not in the classroom, they dare not be too presumptuous.

Tang Qianying was so angry that her head was about to smoke, she stared at this hateful stinky brother in front of her.

Qing Yun shook her head and concluded solemnly, "Sister Ying, I have to say, sometimes you are really a genius, why do you always come up with ideas that can't solve the problem?"

Tang Qianying suddenly became furious, and scratched Qin Manman across from him.

Guan Xiaohe chuckled, "Youngest, you and Manman are really a match made in heaven! Even if you hurt Qianying, your tone of voice is exactly the same!"

Qin Manman stretched out his arms to hug Tang Qianying helplessly, turned his head and said to Qing Yun, "Say less."

But there was a smile on her lips.

This stinky man is very good.

Tang Qianying bared her teeth and claws for a while, and didn't stop until Qin Manman stuffed her with another lollipop.

But what no one noticed was that under her long bangs, the corners of her eyes were curled up with a smile at this moment.

She found out that although she was embarrassed by such a disturbance, the secret targeting of her by several girlfriends was eliminated.

Manga blinked twice, feeling a little puzzled in his heart.

Could it be that this stinky brother did it on purpose?

She sneaked a suspicious glance at Qing Yun, only to see him burying his head and rubbing his chin carefully looking at his test paper.

Tang Qianying murmured in her heart, what's so interesting about this?

Suddenly, a flash of inspiration flashed in her mind.

Isn't this guy trying to help her improve her math performance?

Tang Qianying turned her head and bit her lip quietly, feeling excited and disappointed at the same time.

What is exciting is that as we all know, Qing Yun not only has good math skills, but also has the title of "gold medal coach". Maybe he really has a way with his own math.

What's disappointing is, what the hell, he's just a stinky brother!

Unintentionally flirting is the most hateful thing!
Scumbag!

but……

If you don't care, what's the use of my math improving!

……

"Tang... Sister Ying, I have already written out the solution ideas for the two big questions you got wrong, and I have also written a few similar questions to consolidate, so that you will not be wrong next time you encounter such questions. "

Under Qin Manman's watchful eye, Qing Yun, who originally wanted to call Tang Qianying 'Tangtang' according to her past habits, was forced to change her words.

After thanking Tang Qianying, she took the draft paper he handed over, and sat in her seat to watch it with little interest.

Qingyun's solution is very delicate, but she has no interest in mathematics at all.

Otherwise, it would not have been in such a stagnant situation.

Whether she tried hard or not at this time did not change the result in any way.

She didn't want to leave Xishu, where she was born and raised, to study in another place.

However, the two local 985 schools, Shu University and Chengdian Branch, did not earn high scores in Xishu.

Especially Shu University, at this time, it is only about 30 points on the key line.

This is a level she can't fall below.

"Look at these three theorems." Qing Yun handed over a few more sheets of paper.

Tang Qianying took it with a numb face.

"Cauchy mean value theorem?"

"Hopital's law?"

"Taylor formula?"

Tang Qianying looked at the draft paper in her hand in bewilderment, "Is this the content of advanced mathematics?"

Qing Yun hummed, "Remember one sentence, 'From a high view, there are no secrets'."

A pair of cartoon eyes narrowed immediately, "What do you mean? You mean to say that you stand on the clouds and look down on all beings?"

Qing Yun was almost choked to death by her.

Although he also wanted to look down on her, but now is definitely not the time.

In the classroom, Qin Manman is still beside him.

There will be plenty of opportunities in the future, not only to look down on her twin ponytails, but also to put a mirror next to her!
He swallowed a mouthful of saliva, and explained helplessly, "Simply put, if you look at the world with advanced mathematics, there are no secrets in the world."

Qin Manman curled his lips, "Use advanced mathematics to do the math problems of the college entrance examination. Even if you do it correctly, half of the marks will be deducted from the examination papers of Xishu Province."

"Why? Why don't you give points when you solve it? The marking teacher won't?"

Qin Manman's voice seemed to have been practiced, very penetrating.

Although the base class classroom of the self-study class is not very quiet, the voice of uncontrolled voices can still be heard in every corner.

Wu Jun, the gold medalist in the National Mathematics Competition, raised a question.

Qin Manman knew that this guy was also recommended for admission, and hadn't switched to review mode, so it was normal if he didn't know it.

But she doesn't want to explain.

I don't even want to explain it to other men.

Qing Yun patted the footprints on his trousers, and said helplessly, "Old Wu, let's use your favorite 'Everything Can Be Lost' as an example.

Middle school mathematics does not talk about the definition of 'limit'. "

Wu Jun was dissatisfied, "Why didn't you say it? Isn't it used in the derivative?"

I'm already using it all the time, did you tell me?

Yang Yue was also puzzled, "Isn't the process of approaching the limit? It's written in our textbook."

As soon as these words came out, Wu Jun patted his head, "I understand."

"What do you understand?" Yang Yue was dumbfounded.

I was frankly echoing your point of view, but you came up with this sentence?
Co-authoring makes me look stupid!

Wu Jun smiled at Qing Yun, turned his head and explained, "'Limit' is the concept of advanced mathematics differential courses, and in our high school textbooks, it is considered that "approaching" is the limit, which is essentially correct. .

But high schools generally think that 'approaching' means 'equal'. "

Guan Xiaohe on the side was stunned, "Isn't it?"

Chattering started in the classroom.

They are all good children who love to learn. When they encounter new knowledge points, they instinctively start to pay attention.
Wu Jun scratched his hair, "Youngest, why don't you explain? I'm worried that it will confuse them."

He is very self-aware of himself, and he can solve problems, but not lecture them.

This is super-class knowledge, and he can't bear the responsibility if he is confused by explaining it to his classmates.

Qing Yun patted his trouser legs again, and walked to the podium, "Let me tell you, there is a part of calculus knowledge in our high school books.

But it is the most basic part of advanced mathematics that should be learned in college.

This part of knowledge, if you dig deeper, is very awesome, and it is also the reason why advanced mathematics is called advanced mathematics.

However, here, I only talk about the limit we just discussed, and, pay attention!Moreover, it is only suitable for students who have enough energy to learn. "

"Then you still let me learn!" Tang Qianying said angrily.
