Chapter 257: Encounter in the Canteen
At noon, there were very few students in the teaching building, and Tang Su felt it was particularly quiet when walking in the corridor.
It was more than 100 meters from the teaching building to the first canteen, so Tang Su walked slowly without any hurry. When she passed the publicity corridor, she stopped to look at the new notices and displays.
As expected, the photos from the last sports meet appeared in the bulletin board, and she appeared in two of the photos. One was taken when she was participating in the high jump competition and jumped over the railing. The posture was really beautiful. Another was taken when she won the Sports Star Award and stood on the stage with Xue Yao, Secretary He and Principal Xiao. Tang Su stared at the photo for a while. Her smile in the photo was a bit deliberate, and it was obvious that she was a little nervous. Her unnatural look did not show her best condition. Xue Yao, who was standing next to her, raised the corners of his mouth slightly, and drew a faint smile. He looked handsome, elegant, sunny and handsome. When she stood with him, the light was on him, and she was reduced to a background board.
Tang Su took out her cell phone and took pictures of the two photos. This would be a commemoration of her youth. She wanted to keep these photos, as she might feel deeply moved when looking at them in a few years.
Afterwards, Tang Su came to the cafeteria. There were still some classmates queuing up for food, but the line was not very long, with only eight or nine people in front.
Tang Su stood at the end of the line, then she took out a palm-sized pocket book from her pocket and started to memorize words. This kind of time spent in line was a waste of time, it was just right to use it to memorize a few words.
It is impossible for her to memorize words using the time in class and self-study classes, so this kind of free time is the best time to memorize words.
Tang Su lowered her head and began to memorize. She was so absorbed in studying that she didn't even notice that a minute or two later, several boys lined up behind her.
Until some discussion voices reached her ears: "Yes, the answer to the first question is 4 times the square root of 3."
"What about the second question, Xue Yao, how do you do the second question?"
"The second question is actually simpler than the first question. This question mainly tests the definitions and basic quantities of ellipses and parabolas. The equations can be confirmed through the intersection triangle. First, find the coordinates of the center of gravity of OMA, then find the value of b, and then find the equation of the ellipse based on the question. Once the equation of the ellipse is determined, the equation of the parabola will also be determined."
…
Tang Su was stunned and the book in his hand almost fell to the ground.
She froze in place, as if someone had pressed acupoints on her.
She didn't understand what topic they were talking about, but the voice seemed to have magic, making her heart beat faster.
She didn't look back at the person behind her because she knew who it was.
The discussion continued: "I get annoyed when I see the conic section problem as the last one. Every time I either can't solve it or I can only solve one problem at most."
"Me too. I really don't like this section. It's too difficult and abstract. I'd rather have the derivative questions last, so that I can still have a chance to get full marks in math."
"It is precisely because it is difficult that it has differentiation. If you want to get a high score, you have to understand all the sections thoroughly."
…
The last sentence was said by Xue Yao.
After he finished speaking, the discussions behind him stopped abruptly.
Tang Su also came to the window for getting food.
"What do you want to eat?" asked the auntie who was serving the food a little impatiently.
