Hearing this, Shi Nian slowly stood up, glanced at Rong Min first, and then replied: "Horizontal conveyor belt, when V₀ is greater than V, it may slow down all the time, or it may slow down first and then at a constant speed. When V₀ is less than V, it may be accelerated all the time, or it may be accelerated first and then at a constant speed. ”

When she finished speaking, the class was silent, and they all looked at Shi Nian intently, their eyes full of admiration and admiration. After a few seconds, the teacher looked at the students in the class and said, "Why don't you pick up a pen and write down what you just said?"

Then he looked at Shi Nian and smiled and said, "Sit down!"

Many people have just woken up from a dream, and they have picked up a pen and written and painted in a notebook, and they don't know what to write.

Looking at their attitude of not chasing and not leaving, the teacher couldn't help but say: "Learning, is to be single-minded, if you look around when you should be serious, either in a daze or talking, then even if you sit in the classroom for a year, you will not be able to learn anything." ”

"Your class is the seed class that the school should focus on cultivating, and all the high-quality resources are equipped, if you don't study hard, who are you worth?"

"Do you know how happy you are to be able to sit in such a comfortable classroom and study?" said this, and the teacher's memory box seemed to be opened.

"I think when I was studying, I couldn't even eat, and I walked more than ten miles to school on two legs every day, and it was good to be able to bring a vegetable nest to satisfy my hunger. There are many families who don't even guarantee three meals a day, let alone go to school. ”

"The teachers who teach us, the primary school Chinese teachers are primary school graduates, the junior high school math teachers are junior high school graduates, and many of the high school teachers have not even gone to college. Look at you again, a serious university degree, a senior teacher!"

After being ruthlessly educated by the teacher, the students below were a lot more well-behaved, and the classmates who were secretly talking below just now were so ashamed that they didn't dare to look up.

"Well, having said all this, I just hope that you can cherish the only three years of study, and when you look back at it later, you will not feel regrets and regrets. ”

"Let's move on. ”

。。。。。。

After the bell rang for the end of class, the teacher walked away with his lesson plan, but the students below did not move their buttocks and did not play as usual.

The teacher's initiation is really a shot in the arm!

"Shi Nian, you were great just now. Chen Kui looked at the back of her head and said with a smile.

Hearing this, Shi Nian turned around, grinned a little embarrassed, and said with a smile: "Hehe, no, I just previewed it before class, and you can answer it instead." ”

Can she say that this kind of question is pediatric for her?

Chen Kui looked at her and didn't speak, his face was full of smiles, and his eyes were full of pride. She's always so good, and it's even more cute to be in close contact with her.

Mu Chen, who was on the side, saw that the two of them were chatting happily, pursed his lips, and interjected with a smile: "Isn't it just that I answered a question correctly, as for it?"

After speaking, he glanced at Chen Kui mockingly, thinking that he just wanted to gain favor in front of Shi Nian.

"What is it?Mu Chen, what do you mean by such a weird yin and yang?" Shi Nian didn't want to be praised, he just couldn't get used to this guy's arrogant appearance.

Mu Chen just wanted to ridicule Chen Kui, but he didn't expect to provoke Shi Nian, he glanced at her expressionlessly, then glanced over and snorted, "It's not interesting." ”
