After another week, the teachers in the third year of high school finally realized why the teacher who had taught Shi Ning in class would say, "Every time Shi Ning looks up, I am afraid".

Because......

"There is a simpler calculation, it is recommended to ask for the Cartesian coordinate system as shown in the figure below, and let the earth be located at the focal point F(-,0)......"

Shi Ning opened his mouth, and the teacher knew that, alas, they didn't talk about the most simple and easy-to-understand method, and Shi Ning needed to add.

"Today, I was corrected by Shi Ning again, I have to think twice before preparing for class now!"

"Alas, Shi Ning's knowledge covers a wide range of real Lu Zhi'an and Xi Qinghuan, and today I was mentioned by her, and I was suddenly opened and taught."

"I'll be honest with you, when Shi Ning lowered his head, I was very happy, and once Shi Ning looked up, I knew ...... Something went wrong! ”

……

In the past two weeks, except for the Chinese teacher, who has not had such an experience and emotion, the three teachers of mathematics, physics, and chemistry are trembling together, and the English teacher does not want to speak.

Before, it was Lu Zhi'an and Xi Qinghuan, and now with Shi Ning, have the three of them become tigers! She is now practicing her pronunciation every night after preparing for class.

The Chinese teacher glanced at this, she hoped that Shi Ning could do the same, but she never did.

Make chalk of one and cheese of the other!

"Why don't you talk to Shi Ning and let me, as a Chinese teacher, also feel the opportunity to experience your experiences? I'd love to have. The Chinese teacher looked at his mouth and said that he was afraid, but in fact, the colleagues with happy faces were really annoying.

Teacher Liu, the head teacher, immediately mediated and comforted the Chinese teacher, "Shi Ning's Chinese is indeed a little weak, but she has been working hard, I also heard last night that I went to your dormitory again Teacher Kang?" Alas, is it troublesome for you again? ”

Thinking that Shi Ning came over at eleven o'clock last night to ask for advice, Teacher Kang, who teaches Chinese, laughed, leaned lazily on the office chair, and said with a smile: "No way, Teacher Liu, you also said that her language is a little weak, and she also has a strong sense of crisis, the first monthly exam of this semester is approaching, and she can't work hard, and the first place in the grade is a little difficult." ”

"It's also quite exciting, in the past, Lu Zhi'an, the first in the previous grade, was a permanent resident, and occasionally Xi Qinghuan would turn the tables, first, second, and the exams of the year and month were contracted by them, and this time Shi Ning joined, I really looked forward to it."

The strong duel has always been exciting, and the teachers began to look forward to it early.

Speaking of this monthly exam, the teachers in the office talked a lot and chatted happily.

The physics teacher stood on the podium, looking at Shi Ning for a while, Lu Zhi'an for a while, and Xi Qinghuan for a while, and saw that his eyes were dizzying.

These students, the argument is not exciting, and this time it is Xi Qinghuan and Lu Zhi'an against Shi Ning, a few days ago, it was Shi Ning and Xi Qinghuan against Lu Zhi'an, in short, half a month, such a scene will happen once in three days and two days.

As long as there is a dispute, the three of them will definitely ask each other for advice very seriously.

Before, the teacher was also worried that it would delay the review of other students, and suggested that the three of them should discuss it privately after class, and all the students in the class objected, because they wanted to hear it!

Just now, the three of them stood up, and there was already a five-minute discussion.
