Chapter 54

In fact, Teacher Zhou just wanted to use this method to deepen the impression of the students. Every year, there would always be some small mistakes in the chemistry experiment class. Later, he simply used his deterrent power and fierce appearance to use these common sense, especially safety issues, as This approach impresses new students.

"Article [-], the one in the fifth row, stand up, why can't the windows be closed for burning charcoal at home?"

"You can't just stand, the one in front of you stands up, why!"

"You don't know how to stand and listen to the class, the one in front of you stands up, why!"

"Because carbon burns under the condition of insufficient oxygen to form carbon monoxide, closing the window can easily cause carbon monoxide poisoning..." Lin Yiyi is in the third row of the sixth line, and the students behind will not be punished to stand and click on the front one, so Soon it will be her turn...

Besides, this question is not difficult, there are a lot of news about carbon monoxide poisoning, even if she didn't review during the winter vacation, she would still answer it, let alone she reviewed it!Great review!
Ah!Finally a student with common sense in life!Teacher Zhou is very pleased!Bad chemistry can easily kill people!That's enough, the head teacher of class one said to let him choose the class representative himself, that's all!
Teacher Zhou tried hard to give her future class representative a good-natured smile, but it still looked like a threatening smile... "What's your name?"

"My name is Lin Yiyi."

With a whoosh, Teacher Zhou's face collapsed, even though she was fierce enough before... Lin Yiyi is like Monk Zhang Er who can't figure it out, is her name so unpopular?

Teacher Zhou looked at the note in the teaching plan with a dark face. At that time, the teacher in charge of the class, Teacher Su, said kindly, "Old Zhou, you can choose your class representative, oh oh, just stagger the students on the list." Yes, they basically already have jobs, and they may not be able to take part-time jobs.

Lao Zhou only came to his senses at this time, who made the chemistry class start late!Who made chemistry the last subject of the senior high school entrance examination!The students he likes have already been divided up by other teachers!This Lin Yiyi is obviously the third one on the list, with the study committee members marked on the side, the two above are the monitor and the deputy monitor, and the representatives of each subject are listed below...

What old week is up to you to choose!What the hell is this choice!You can see that there are already ten of them, and there is only one with a bit of savvy and common sense!

"Lin Yiyi, well, the study committee member, then let me ask you, what does hydrogen become when it burns in oxygen?" Lao Zhou decided to ask two more difficult questions. If she can't answer them, it means that the preview is not very good It's in place, but with better common sense, at least the sense of loss will be less.

"Water." Lin Yiyi felt weird, why did Teacher Zhou's tone seem to pose a big problem for her?
"What is the common valence of iron?" Mmm, Mr. Zhou thought proudly, asking multiple-choice questions in the way of asking single-choice questions is a trap he is good at.

"+2 or +3." The knowledge points of the high school entrance examination.

"Magnesium is more active or aluminum is more active?" After Teacher Zhou asked the question, this time Monk Zhang Er became the majority of students confused, what?What is Teacher Zhou asking?Beautiful and lively or female and lively?Isn't it the most cheerful and lively beauty?
"Potassium, calcium, sodium, magnesium, aluminum, zinc, iron, tin, lead, hydrogen, copper, mercury, silver, and platinum?" Lin Yiyi understood what Teacher Zhou was asking, and directly recited the order of metal activity in junior high school. She remembered this stuff very well. Because it was taught by Mr. Zhou back then, Mr. Zhou has no taboos in teaching, regardless of his face, and there are a lot of messy jingles.

Back then, he copied a joke for everyone to recite, "Pick up a big beautiful woman with a slender body, weighing a hundred catties." So the boys memorized it very smoothly. When Yiyi walked past the podium, she recited this jingle aloud and laughed at her... How do you think Lin Yiyi can't remember it well...

However, this conversation seemed to the students as if Mr. Zhou was checking signs with Lin Yiyi!Hey, I can't even understand, what the hell!Oops, they will be "the king of heaven and the tiger of the earth" in a while!
Teacher Zhou was excited, "Have you read the periodic table of elements by heart?"

"Helium helium lithium beryllium boron, carbon nitrogen oxygen fluorine neon, sodium magnesium aluminum silicon phosphorus, sulfur chloride argon potassium calcium?" Lin Yiyi stopped after memorizing 20.

"Go on!" Lao Zhou urged.

Lin Yiyi couldn't help scratching her head, and asked suspiciously: "Teacher, isn't the middle school exam of the periodic table of chemical elements only the top [-]?"

"Oh, that's right, that's all right, you can sit down, um, all the students who are standing can sit down."

Lao Zhou opened the lesson plan, stopped asking students to ask questions, and planned to start the formal class.What?The list of small notes in the lesson plan?Throw it away!Throw it all away!What's so good about being a study committee member? It's an empty job with no rights!His chemistry class representative is this girl!No one will change him!
Just kidding, as a man who studies chemistry with an alcohol lamp in his left hand and concentrated sulfuric acid in his right, with a bandit face and scars on his face, who would dare to compete with him for his students!He is not afraid of anyone coming!
Ah Xie, Lin Yiyi, who was sitting down, suddenly felt that in March, it was cold in the spring, and it was a bit cold!
