The chemistry teacher was an old man with gray hair and reading glasses."
I'm going to retire, and I'll retire after teaching you."
He smiled, visibly seeing that there was still a tooth missing.This is the opening remark of each of his classes, and it is said that he has reached retirement age, but the school insists that he teach for another year.He knows a lot, is very knowledgeable, and even at this age, he is still not old, he can be described as "vigorous", and he is a humorous old man."
In this lesson, let's talk about experiments, the phenomenon of magnesium strips burning in the air.""
Let's do the experiment!"
Meng Huanhuan muttered quietly, her tone a little excited.Yin Xiaoxing sat up straight and looked at the teacher, and his serious appearance made Yechen can't help but look at it twice."
So what happens when magnesium strips burn in the air?"
He rubbed his hands together with some excitement."
We need to find a classmate to come up and experiment, which classmate volunteered?"
As soon as the words fell, Tang Minghao directly raised his hand and got up and said, "I'll come." ”"Okay, this is a new classmate, right?"
The teacher smiled, his gray beard trembling and trembling."
That's the right teacher, my name is Tang Minghao."
Tang Minghao stood on the podium and spoke to the teacher very familiarly.The teacher nodded and said, "Okay, okay, Tang......
Don Jr., Don Jr., here you come. ”"The teacher still can't remember everyone's names."
Zhang Yifan smiled helplessly, then kicked Meng Huanhuan's stool and said, "Huanhuan, what phenomenon can there be when the magnesium strip burns?"
”"Mijo?
Maybe the air can be beautiful. ”Meng Huanhuan said casually.This sentence fell into Wang Jieting's ears, and she said sarcastically: "Heh, mentally retarded." ”Tang Minghao took the magnesium strip from the table and lit it in a safe place as instructed by the teacher.The magnesium bar burns quickly at a speed visible to the naked eye, and at the same time emits a dazzling bright light, which is very beautiful."
See, students, this is the phenomenon of magnesium strips burning, emitting a dazzling bright light, and at the same time emitting a lot of heat, generating white smoke and a white substance."
The teacher smiled and continued, "Very good, very good, this classmate should go back." ”Tang Minghao looked very excited, jumped off the podium, and didn't forget to throw a wink at Yin Xiaoxing in the last row.Yechen's face suddenly became gloomy.Yin Xiaoxing subconsciously looked at Yechen with a weak heart, and he didn't know how to say anything about his rare displeasure."
Tut, look at it, the broken child is making people jealous again."
Zhang Yifan sighed and said, "Huanhuan, you are not allowed to see if he hears it." ”"I heard it, I heard it."
Meng Huanhuan responded helplessly.It was time for class to be over, but Tang Minghao suddenly sat down in front of Yin Xiaoxing and said, "Xingxing, what are you doing?"
”Yin Xiaoxing leaned in front of his forehead and said without raising his head: "Write the question." ”"Why are you so cold, what are you writing?"
Tang Minghao got up slightly and leaned towards Yin Xiaoxing.Yechen finally couldn't help it, and pushed his head directly with one hand and said, "It's too close." ”"Nonsense, it's still so far away."
Tang Minghao looked at Yin Xiaoxing with a grimace and said, "Look at it, our country A is still too feudal, when I was in country M, girls could be hugged and kissed directly." ”"Shut up."
Yin Xiaoxing seemed to have felt Yechen's murderous aura."
Xingxing, why are you so fierce to me, why don't you murder him."
Tang Minghao said aggrievedly, "You will be sad if you are biased towards others like this." ”()
