"Sister Gui, are you free for the next class?"

As soon as the two classmates were sent away, Lao Hu took out his mobile phone and dialed Teacher Huang Guijie.

Teacher Huang Guijie is the head of the mathematics teaching and research team in the third year of high school, she has a bold and spicy personality, she is famous for her naval battles in teaching, and the classes she brings are also talented, so the people of the rivers and lakes give her the nickname "Ice Emperor Mu Guiying"!

As soon as the phone was connected, there was a burst of impatient shouting on the other end.

This tongue-like pronunciation is undoubtedly Sister Gui's own deity at a glance: "Yes, yes, what's the matter with Director Hu!?" ”

"We have two students who are going to participate in the Hongchuan Cup competition!"

Although Director Hu is short-tempered, Huang Guijie is not a fuel-efficient lamp, once the two of them quarrel, it will be a needle against Maimang.

However, teachers with a level like this are generally a little tempered. Therefore, Director Hu had no choice but to put down his body and asked carefully, "If you can, can you help with counseling?" ”

"Okay, I'll be there soon!"

"Thank you, big sister, thank you, big sister!"

Huang Guijie is also refreshing. After all, this teacher, although he is a short-tempered master, still responds to students' needs. Hu Kaitian finally breathed a sigh of relief and hung up the phone with thanks.

......

Soon after, the department on the second floor.

The teaching and research room is filled with the fragrance of ink.

In this small space, there are piles of white paper like snow-capped mountains, and dozens of photocopiers and printing presses, like a medieval workshop.

All the exam papers and materials of Ice Emperor High School are continuously produced from here.

Therefore, every human being who has been here calls this the "Demon Cave Capital"!

And Tang Long, when he walked here, he didn't have any fear. In the journey to learn God, he has gradually fallen in love with brushing questions, and this terrible feeling is like "eating marrow and knowing the taste"!

"Tang Long, it's here so soon!"

Director Hu has just walked into the teaching and research department and is about to light a cigarette for recreation. I saw Tang Long, holding a pile of various teaching aids and a stack of stationery like a small hill, and broke in.

It was quite like the momentum of King Chuang, so frightened that he hurriedly put the cigarette box into his pocket: "Today, Teacher Gui, I will give you special counseling, why did you bring so many guys here!" ”

"Say it earlier!"

Tang Long's face was frustrated, what is the point of tutoring without brushing questions?

"Knock knock!"

Outside the teaching room, there was a knock on the door that made people ring. This sound is like the momentum of a barbarian battering ram bombarding the city gates, as if the gates are going to be demolished!

"Alas, this woman!"

Lao Hu was very helpless, he sighed silently, and hurriedly opened the door for her.

As soon as the door was opened, a woman with dark brown hair and a bloated body broke into the teaching and research room with all kinds of materials. Director Hu saw that she still didn't change her teaching, so he cheekily said to her: "I said Sister Gui, knock on the door next time, other classes are still in class!" ”

"I'm sorry, I'm sorry!"

Teacher Huang Guijie wiped his sweat and said in a thick voice: "Director Hu, I'm sorry, I'm a little late today, I must be light next time!" ”

"Uh-huh!"

Accept it with an open mind and never change it!

"Lao Hu, which two classmates are coming to make up for the class?" Huang Guijie brought a chair and sat down at an empty table while asking Hu Kaitiandao.

"Tang Long, Guan Yao!"

The old man on the side hurriedly responded.

"Tang Long?" Huang Guijie looked at Tang Long, as if he remembered something: "You are the one, the classmate who has been in one shift and one after another?" ”

"Uh..."

This sentence hits the pain point.

Director Hu on the side, seeing Tang Long's embarrassed face, hurriedly said: "Sister Gui, Tang Long's previous grades were not good, but he has studied hard recently, and this progress has improved by leaps and bounds!" ”

"I heard Mo Jiahua say that he can score 1120 points in his recent exam!"

"Yes, it seems that the qualifications are okay..."Huang Guijie then looked at Tang Long, and his original disdain was much less. However, she added: "However, this competition, he is not like an ordinary exam!" ”

"I've taken quite a few students with me!" Huang Guijie grabbed her short hair and seriously recalled the past: "Many of them have excellent grades. However, even before the difficult problem of the competition, I can't turn the corner! ”

"Competition, not only will destroy people's self-confidence, but also delay the review time, and even affect the mentality, so if you want to participate, you must carefully weigh the pros and cons!"

Director Hu was dizzy when he heard this bunch of words.

However, Sister Gui's words are also very pertinent. After all, the super difficulty of the Hongchuan competition is beyond the reach of ordinary people, and if you have to fight with the tactics of the sea of questions, sometimes it has little effect. So, he looked at Tang Long a little worriedly, and asked cautiously, "Tang Long, do you still want... Do you want to participate? ”

"It's okay, I'm going to participate!"

"Okay, then let you try!"

Tang Long's determined look made Huang Guijie feel crying and laughing, so she pulled out a competition exam paper from the thick stack of materials: "This is the real question of the Hongchuan Cup competition, or you can do it on the spot, if you still want to participate in the competition after you finish it, then the teacher will continue to tutor you!" ”

"Okay!"

As long as it's a roll, it's done!

Tang Long, take a deep breath.

Roll in!

At this time, Guan Yao also walked into the teaching and research room.

Huang Guijie stood up, handed her the same paper, and said: "This paper is the most common paper of the Hongchuan competition. ”

"This kind of paper, zero points are very common!"

"Teacher, I can only do it, I wish you good luck!"

Zero points, is it the norm?

Tang Long scratched his head, his score of one hundred and five, if he wants to compete in the math competition, even the simplest one, it may be extremely difficult!

Take a deep breath!

The cap pops out, and the nib is disemboweled!

The momentum is really good.

However, when he saw the first question, half of his faith was gone!

1) Delete the positive integer number series 1, 2, 3,... , we get a new sequence, and the 2003rd term of this new sequence is ()

A）2046 B）2047 C） 2048 D）2049

That's just... Question 1!

Sister Gui didn't scare me, zero points are indeed possible!

Let's take a look at the second question?

2) Let a, b belong to R, and ab is not equal to 0, then, the graph of ax - y + b = 0 and curve bx^2 + ay^2 = ab is ()

After that, it's a bunch of puzzling graphics!

Alas, this is bullying me for not learning, ellipses and hyperbolas?

Tang Long was very frustrated, he propped his head, turned his pen helplessly, and stared blankly at this exam paper...

At this time, a line of black letters suddenly appeared in front of his eyes!
