"Your English teacher is still focusing on grading, and this lesson will be changed to physics."

Physics teacher Wang Jianjun's words made Lin Xun and Wang Zihao stunned.

Get!

The face slap has to wait.

The two sat listlessly in their seats.

They are not so looking forward to slapping their faces at the moment.

It's a bit boring.

Who is the slap in the face for?

Tang Qianying was a little sleepy.

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

Shielded by the stacked books on her desk, she stretched, "I'm so sleepy today!" ”

A standard stretch that shows off the curves in front of you.

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

Qingyun, who was blocked by the back of her head, sighed in her heart, buried her head and began to carry the creature.

See what's going on?

You won't lose your position as a 'big woman'.

This mother-in-law is good at everything, but she is a little stingy!

Tang Qianying took out a bottle of wind oil essence and dripped it on her own person, "You have to wake up quickly, it's a physics class." ”

She had planned to relax in this English class.

English is her forte, and she has never scored below 145 since she entered high school.

Qin Manman asked her for wind oil essence and dripped it on the toilet paper and put it aside, "It's just right to take some simple subjects when you're not sober." ”

Guan Xiaohe, who was in the front row, turned his head angrily, "Manman! I see you're itchy today! ”

Yang Yue next to her covered her mouth and smiled, "You haven't seen it yet?" Manman: Today, this is a female competition!

Only a high-IQ mother can give birth to a high-IQ child, you say yes, Qingyun. ”

Qin Manman suddenly exploded, and a pair of long legs kicked the chairs of the two unscrupulous girlfriends underneath.

Tang Qianying's expression froze when she heard this, and she looked at Qin Manman, who was making a fuss, and was shocked in her heart.

Did she see it?

She saw it!

A pair of comic eyes narrowed.

Good for you, Qin Manman!

I didn't say I was going to rob you, so I'm going to play tricks for my sister here, right?

Do you believe it or not......

Tang Qianying's shoulders suddenly fell again.

Never mind.

Alternate to get along, and you will guard against it if you change it.

Girlfriends.

The reason why girlfriends become girlfriends is because of the so-called: "things gather like people in groups".

The interests, appreciation levels, and appearances between girlfriends are similar, and their temperament, temperament, temperament, and behavior are very similar, otherwise they would not become 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 are also prone to liking girlfriends.

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

Well, Manman, I'll admit it, you're right.

I do like him.

However, Qin Manman ......

Will you really be able to go on with him for a long time?

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

"Students, the second diagnosis test paper is still being corrected, and all the after-class questions assigned last time have been done, right?"

Wang Jianjun stood on the podium and began to flip through the scrolls in his hands.

"It's over! I forgot! ”

Tang Qianying immediately came to her senses, and she didn't move a word about the homework assigned before the second diagnosis exam.

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

"And what about the bad news?" Hearing that the study committee members didn't do anything, Tang Qianying's heart settled down a little.

Zhou Li grinned, "The bad news is that I can do it in 3 minutes." ”

Tang Qianying was speechless.

These girlfriends are bullying themselves together today, right?

"Qin Manman, you can talk about this question."

Wang Jianjun saw that there was some commotion in the back row, so he simply named Qin Manman, the center of the commotion.

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

Wang Jianjun interrupted her with a frown, "Qin Manman, what are you reading the question for?" ”

Qin Manman's eyes looked at the question list, "Elder Wang, since I have just started class, I think the students need a little time to focus on the class. So I'm going to read it with the title. ”

Wang Jianjun smiled and nodded, worthy of being the first in the grade!

That's how thoughtful things are!

It's really cheap, Qingyun's kid.

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

Qingyun is his protégé, so naturally he is pleasing to the eye.

It's a bit weird, though.

This stupid boy, how can he look at his own daughter-in-law like this?

At this time, Qingyun looked at the blank question list in Qin Manman's hand beside him, and was dumbfounded.

This mother-in-law doesn't seem to be so honest!

Read the questions because she needs time for mental arithmetic.

"The first question is the common velocity of the moment when the sphere and the wooden box meet, we let the first ball and the wooden box meet, the speed of the two moving together is v1, according to the law of conservation of momentum, after substituting the data, the answer is 3m/s.

The second question is actually about displacement, we set the distance between the first ball and the wooden box from the left end of the conveyor belt is S......"

Wang Jianjun applauded, "The ideas and answers to this question are correct, and Qin Manman spoke very well. ”

Just as Qin Manman was about to sit down after a reserved smile, Wang Jianjun added, "Just remember to do your homework next time." ”

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

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

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

This kind of treatment made Qin Manman a little envious.

In physics, she couldn't get a perfect score, so naturally she had to do the questions honestly.

Wang Jianjun also left the classroom, he had just finished reading the paper, and he had not yet had time to go to the toilet.

Qingyun in the classroom was a little helpless.

After almost two hours of working on liberal arts topics, his brain was a little wooden.

Qin Manman also knew about this situation and let him rest and rest.

After quickly solving the first question, Tang Qianying began to be in a routine daze with the last two questions of the finale.

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

Just now, Yang Yue's remarks of 'female competition' came to my heart again.

She snorted coldly.

All right!

It seems that his performance of being anxious for Qingyun in math class fell in the eyes of people with a heart, and he was a bird.

She glared at Qingyun angrily, but unexpectedly, the eyes of the two touched Qin Manman's back.

Qingyun grinned at her, "Show me your math papers, I'm almost asleep." ”

Tang Qianying didn't want to deal with him.

But when she thought of the word 'female competition', her heart was on fire, and the ghost sent the scroll over, "Why my scroll?" ”

Qingyun took the paper and said sincerely, "I like to study your problem-solving ideas. ”

Tang Qianying, Qin Manman in the middle, and the few people who were listening secretly looked confused.

Tang Qianying's mathematics, what can be the solution ideas?

"Your ideas make me feel like it's a solution I can't think of."

Tang Qianying: ???

Qin Manman: ???

Chen Yue: ???

The faces of the people who eat melons are collectively full of question marks.

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

Qingyun's words made everyone laugh uncontrollably.

Fortunately, it was a classroom, and although the teacher was not in the classroom, they didn't dare to be too presumptuous.

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

Qingyun shook his head and summed it up seriously, "Sister Ying, I have to say, sometimes you are really a genius, why can you always come up with these ideas that can't solve the problem?" ”

Tang Qianying suddenly exploded, and went to scratch him through Qin Manman.

Guan Xiaohe sneered, "Boss, you and Manman are really a natural pair!" The tone is exactly the same! ”

Qin Manman stretched out his hand to hug Tang Qianying helplessly, turned his head and said to Qingyun, "You don't say a word." ”

But a smile appeared on her lips.

This stinky man is quite good.

Tang Qianying opened her teeth and danced for a while, until Qin Manman stuffed another lollipop before it stopped.

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

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

The comic blinked twice, and there were some doubts in his heart.

It can't be that this stinky brother did it on purpose, right?

She peeked at Qingyun suspiciously, only to see him burying his head and touching his chin to look at his test paper carefully.

Tang Qianying muttered in her heart, what's so good about this?

Suddenly, a flash of inspiration flashed through her mind.

Isn't this trying to help her improve her math scores?

Tang Qianying turned her head and bit her lip quietly, excited and lost in her heart.

Excitedly, as we all know, Qingyun not only has good mathematical skills, but also has the title of 'Gold Medal Coach', and he may really have a way to do his mathematics.

What's sad is that, he's a stinky brother!

Unintentionally sultry is the most hateful!

Scumbag!

But......

If you're not careful, what's the use of me improving my math!

……

"Sugar ...... Sister Ying, I have already written you the solution ideas for the two big questions you were wrong, and by the way, I also came up with a few similar questions to consolidate it, and it shouldn't be wrong next time I encounter this kind of question. ”

Under Qin Manman's eyes, Qing Yun, who wanted to call Tang Qianying 'sugar candy' according to his past habits, was forced to change his words.

Tang Qianying thanked him and took the scratch paper he handed over, and sat in his seat and watched with interest.

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

Otherwise, it would not have been in such a state of not being able to go up or down.

She tried not to work hard at this time, and nothing changed the result.

She didn't want to leave her native Xishu to study in a different place.

The two local 985 schools, Shu University and Chengdian Branch, did not have high scores in Xishu.

Especially Shu University, at this time, it will focus on 30 points on the line.

This is a level that she can't fall under.

"Look at these three theorems." Qingyun handed over a few more pieces of paper.

Tang Qianying took it with a numb face.

"Cauchy's median value theorem?"

"The Law of Lobida?"

"Taylor's formula?"

Tang Qianying looked at the scratch paper in her hand with a confused expression, "This is the content of advanced mathematics?" ”

Qingyun snorted, "Remember the saying, 'Under the high view, there is no secret'." ”

A pair of comic eyes suddenly narrowed, "What do you mean?" Are you trying to say that you are standing in the clouds and looking down on all beings? ”

Qingyun was almost choked to death by her.

He wanted to look down on her, but now was certainly not the time.

In the classroom, Qin Manman was still beside him.

In the future, there will be an opportunity, not only to look down on her double ponytail, but also to put a mirror next to her!

He swallowed a mouthful of saliva and explained helplessly, "To put it simply, if you look at the world with advanced mathematics, there are no secrets in the world. ”

Qin Manman pursed his lips, "Use advanced mathematics to do college entrance examination math problems, even if you do it right, Xishu Province will deduct half of the score." ”

"Why? Why don't you give points when you solve it? Marking teachers won't? ”

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

Although the base class classroom of the self-study class is not very quiet, the voice of the voice that does not control the volume can still be transmitted to the corners.

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

Qin Manman knew that this product was also a guaranteed student, and it was normal not to know that he had not switched to review mode.

But she didn't want to explain.

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

Qingyun patted the footprints on his pants and opened his mouth helplessly, "Lao Wu, let's use your favorite 'everything can be Luo's law as an example.

Secondary school mathematics does not speak of the definition of 'limit'. ”

Wu Jun was not convinced, "Why didn't you talk about it?" Isn't that where the derivative is? ”

I'm using all the special ones, and you told me that you didn't tell me?

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

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

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

I'm trying to agree with your point of view, and you end up saying this?

Co-authoring shows me stupid!

Wu Jun smiled at Qingyun and turned his head to explain, "'Limit' is the concept of the Advanced Mathematics Differential Course, and in our high school textbooks, it is essentially correct to think that "approaching" is the limit.

However, in high school, it is generally believed that 'approaching' means 'equal'. ”

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

The classroom began to chatter.

They are all good children who love to learn, and when they encounter new knowledge points, they instinctively begin to pay attention to them.

Wu Jun scratched his hair, "Boss, why don't you tell me?" I'm worried about confusing them. ”

He is very self-aware of himself, he can solve problems, but he can't lecture on them.

This is originally super-class knowledge, and he is confused to teach his classmates, and he can't afford this responsibility.

Qingyun patted his trouser leg again and walked to the podium, "Let me tell you, we have some calculus knowledge in our high school books.

But they are the most basic parts of advanced mathematics that were originally studied in college.

This part of knowledge, digging deeper, is a very good existence, and it is also the reason why higher mathematics is called advanced mathematics.

But, here, I'm just going to talk about the limits we just discussed, and, attention! Moreover, it is only suitable for students who have spare time to learn. ”

"Then you still let me learn!" Tang Qianying opened her mouth indignantly.
