"Okay, then let's take a look at question 23. www.biquge.info For this problem, the elliptic equation is known, and the requirement is to find the extreme value of the area of the quadrilateral......"

"There is a chicken leg ~~~~~~ in the cafeteria tonight"

Ghostly voices echoed throughout the classroom.

Riots and commotions.

For this problem, it is relatively easy to solve the problem by setting the form of two straight lines intersecting the ellipse as x=ky+b. The next step is to follow the equations, as usual, using the Vedic theorem......"

"There is a chicken leg ~~~~~~ in the cafeteria tonight"

Ghostly voices echoed throughout the classroom.

Riots and commotions.

"Next, we can smoothly use k and b to represent the equation for the area of the two triangles, and then add them up to give the area of the entire quadrilateral. The calculation process at this step is complicated, so you need to be careful when calculating......"

"There is a chicken leg ~~~~~~ in the cafeteria tonight"

Ghostly voices echoed throughout the classroom.

Riots and commotions.

“…… I'm talking about you. On the podium, the chalk-clading math teacher could no longer ignore the commotion in the classroom. Putting down the chalk, he patted the chalk ash on his hands, "There are chicken legs tonight, I can understand your excitement." But ah,"

"If you want to grab chicken legs, how can you not take the lead without me as a teacher!"

Shocked by the math teacher's sudden words, I almost fell off my chair while I was in a daze. Straightening my glasses, I widened my eyes as I watched as the math teacher took out his simple aluminum lunch box and tapped rhythmically with chopsticks:

"Okay guys, the forward of our army came to report, and the front canteen found freshly cooked chicken legs. In my opinion, for today's plan, the only way to start is strong, and then to suffer, now according to the end of class there are still five minutes, the rest of the classes have not been out of class, it is a good opportunity for us to win the first move, to compete for chicken legs. Little ones! ”

"Order!"

Hearing the math teacher's words, there were quite a few boys in the class - hey the discipline committee I said you are not a man to join in the fun - well, quite a few of them took out their lunch boxes, stood up and made a gesture of eagerness towards the door.

"Kill me to the cafeteria~~~~~~~~"

"Kill-kill-kill-"

With the order of the math teacher, the gang immediately rushed out of the classroom through the front and back doors, and followed the math teacher's figure towards the cafeteria, and the footsteps resounded throughout the east teaching building. The negative effects of this act were immediately apparent, and the commotion of the other classes could be clearly heard even here. At this moment, the math teacher is definitely going to be disciplined by the top brother, and the friends of the students are not so easy to be, and maybe there will be salary deductions......

But the other teacher caused more trouble than him. Pulling out the bread that had been prepared a long time ago, I tore open the package and sighed, and the figure standing on the podium this morning came to my mind again. Anyway, Zi Ma, what did you do when you made a special trip to this third-tier small city? Is it purely to tease me?

The bread in his hand was quickly finished. Thinking that the cold was not cured, I took out two packets of cold medicine, tore them open and poured them into a cup, and then connected a full cup of hot water to the water dispenser in the back and reopened it. Alas, there have been really a lot of things that have happened lately, and I died of a headache......

The water is too hot, and it will have to be dried for a while. I don't want to do my homework at all...... Let's sing a song. It's good to sing a little. It's been a long time since I've sung it...... Let's take a paragraph of "Sitting in the Palace" in "Shiro's Mother".

"Princess," let's start with Yang Shilang's recitation. When singing, the "lord" behind the "princess" always has to be biased, and it sounds delicious...... Forget it and start singing, "I have a lot of kindness with your husband and wife, so why should Princess Xian be too apologetic." Yang Yanhui had a sad brow one day, and vowed not to forget the grace of Princess Xian. ”

"What do you say about the kindness of husband and wife, we are thousands of miles away from you to marry. For some reason, you are worried all day long, and you can only say anything about your confidants. ”

Next is a large section of Sippy Allegro, which is quite enjoyable to sing and sound. As far as Princess Tiejing's paragraph just now, the turn in the pronunciation of the three words "what" sounds very comfortable, the word "have" is slightly lengthened, and "what" and "heart" follow in one breath...... But my imagination has grown richer and richer, and the feeling of duet can be imagined to be so concrete. It seems that this is also the influence of writing fandom, right?

"It's not that I've been worried these days, and I don't dare to say anything about my confidants. Xiao Tianzuo put the two countries at war, and my mother came to Beifan with grain and grass. I have the heart to go back to Song Ying to see my mother, but I am far away from the world. ”

"You have to be clever to argue there, and if you want to worship your cousin, I won't stop you."

"Although the princess does not stop it, there is no way to pass the level."

"I have the heart to give you gold arrows, I'm afraid that you won't return them once you go."

"The princess gave me a golden arrow, and I will return it as soon as I see my mother."

"Song Ying is far away from here, how can you return it overnight."

"The princess just magnified her courage and hurried to return it overnight."

"The right person calls our alliance vow, and you are ——! to the sky."

"Table", this place can actually be applauded...... Princess Tiejing, this is going to make Yang Shilang swear. Then you have to kneel on the ground...... Hawkers, anyway, there aren't many people at this time, and it's quite interesting to kneel for self-entertainment.

"The princess made an oath to me, and knelt on the ground and Pingchuan." It's definitely not appropriate to get down on your knees all at once. Mimicking the influence of memory, I lifted up the robe that did not exist, "If I visit my mother, I will not turn back - turn ————"

"How's it going?"

"That's fine." These two words, there is always a feeling that Yang Shilang wants to get out of the way, "Yellow sand covers the face - the corpse is not - all ————"

At that time in the Northern Song Dynasty, it was indeed quite serious to make this kind of oath...... That's all for today, it's just to entertain yourself, quickly stand up and pat the soil on your pants and get ready for evening self-study......

"It's too serious~~~~"

Suddenly, a hand stretched out in front of me, looking like it was trying to help me up...... Ay? Help me up?

Looking up along these hands, my heart began to tremble again—Yakumo-sensei, why are you here? And, if I'm not mistaken, the pronunciation just now is...... Coming out of your mouth?

I said why the duet imagination in my mind this time is so specific and vivid! No, the slot doesn't seem to be here...... Mr. Yakumo, can you tell me why you are here to sing an excerpt from "Shiro Visits His Mother" with me? What the hell is wrong with this world!?

In front of me, our Yakumo-sensei was still holding out her hands, waiting to pull me up. Cautiously passing my hand over, I stood up in the warmth of the envelope, and I was in a state of complete unconsciousness. What happened today hit me no less than the night before: Yakumo Murasaki is a citizen of the People's Republic of China, of Russian ethnicity, and he and I sang "Shiro Visits His Mother" in the classroom at dinner time......

Nima gives back my three views! Come back!

"As soon as I saw the vow of the Horse Alliance, our family relaxed our hearts." Seeing me stand up, the person opposite smiled slightly, and then opened his mouth again to continue-Are you really going to continue, dear Yakumo-sensei!? "You're here, Qiao Gai - pretending to be ————"

There should be a gong and drum guy after this Xipi is finished, and then it is changed to Xipi rocking board, and then it is the last sentence of Princess Tiejing on the field, and after singing it, she should get off the stage and go to steal the arrow......

"Steal the order-arrow, you-———— out, close ————!"

Well, then it's time for Princess Iron Mirror to get down...... Anyway, I don't want to keep singing, so it's just over. Wiping the sweat from my head with my hands, I was just about to sit down when I suddenly found that the "Iron Mirror Princess" was still in place, looking at me with that slightly expectant look. When I looked at that look, a sense of guilt suddenly rose in my heart.

Is this for me to keep singing? Indeed, Yang Yanhui still has a paragraph, and it is better to finish singing. I want to think of words...... Damn, "It's called Xiaofan"!? This TM is a high-pitched voice, how can I sing at a non-professional level!

Seeing that I still didn't react and was about to sit down, the other party suddenly puffed up his face slightly, showing a lively expression...... Okay, I'll sing, I'll sing, I'm out of the way, I'm not okay to sing! Don't look at me with that look, I can't stand it!

"When I saw the princess stealing the arrow, I couldn't help but be happy in the palace. Standing at the palace gate—"

I know how Yang Yanhui felt when he was forced to swear. Success or failure is in this move, and it depends on this sentence whether you are ashamed or not, but the tone is a little high at the beginning...... Hold my throat!

"It's called ———— ————"

"Good!!"

Hearing the applause, I couldn't help but look back and find that at some point, there were already a lot of teachers gathered at the back door, and the math teacher who had just come back from the cafeteria was carrying his aluminum lunch box with rice and four chicken legs...... Anyway, if you grab four alone, what do you let others do, math teacher! You can't do that as a teacher!

Anyway, the hurdle of "Called Xiaofan" is over...... I'm sweating, there's still the last sentence left, and after singing it, I quickly rested, and the temperature of the cold medicine was almost drinkable.

"Prepare for the master's war horse, buckle the chain——, master is good to get out of the customs————"

I'm finally done singing, I'm tired to death! No, I want to rest, I must rest......

Slumping into my seat just like during the day, I took a few deep breaths. I was about to drink the cold medicine to moisten my throat, when a warm breath suddenly blew in my ears:

"It's a good song, Wangwang."

"Wow" jumped up from the chair all of a sudden, and I hurriedly took a few steps back: "Teacher Baba, Baba, Bayun, didn't I say it, don't make this kind of joke, I can't stand it for high school students!" ”

"Ahla," moved my chair over, and sat down with Yakumo Murasaki, who was still playing against me just now, "Some people want to, but they don't have this opportunity yet." In this case, you will be jealous of some people, Wangwang. ”

"Is there something you're here for?" Calming myself down, I hurriedly forced a reversal of the subject, "Is there a new volume in the mimeograph room that can be used as homework?" I'm going to count out the number of people in our class right away......"

"I'm not going to do that kind of thing." Holding out a finger and waving in front of her, she stood up, "I've already said that I won't leave homework today." It will never stay. I'm here to ask you for something. ”

"Looking for me? What's the matter with me? ”

Are you looking for me to sing? But Mr. Yakumo, how exactly did you learn Peking Opera, can you tell me? This fact is terrifying!

"At first, I thought it was interesting, so I studied it for a while, but in the end, I only learned this one, which is really ashamed. Of course, it's much better than foreign operas, but I can't master that kind of pronunciation technique anyway. Sensing my doubts again, Yakumo Zi hugged his shoulders, "Okay, Wangwang, come with me to the office." ”

“…… Oh. ”

I hope I don't get teased again and again, I really can't stand it......
