The seconds passed.

I don't know what the hell the reason is, the classmates in the audience all feel that Fang Nian is looking at themselves, and some people can't say it even if the words come to their lips.

Some of them remembered the rumors on the official opening day.

also remembered the former eight middle school and one tyrant, and now Chen Yao, who is suspended from school.

As a result, the sound in the classroom ranged from rustling to falling pins.

After a few more moments, Fang Nian spoke.

"If you don't want to listen to the class, you can do your own thing, don't talk small, and disturb others. ”

After thinking about it for a while, Fang Nian decided to say a little more, after all, there were three more math lessons to be taught in the future.

"I know that you are not convinced, why are you all students, but I will give you a lecture, in fact, I don't know what the hell the teacher asked me to substitute for the teacher. ”

"In the past two days, the school has been seriously criticizing the matter of early love, and it just so happened that I heard a little story and shared it with you. ”

"At your age like you and me, it's normal to have someone you like, but it's better to keep it in your heart. ”

"Because in the eighth middle school, it is easy to be caught and disciplined by the political and religious department, and it is easy to be rejected after confession, and you feel that you are out of love, in fact, you are pure unrequited love, it is called love at first sight when it is said well, and it is called love at first sight if it is not good to say, where is the lovelorn at all. ”

There was a faint laugh in the classroom.

Fang Nian knocked on the podium, and the audience was quiet, and then he continued.

"If you like someone, while thinking about him, do a math problem. ”

"When you graduate, put the book full of questions in front of him, and tell him how much you like him, whether it's a boy or a girl, don't believe him and don't move!"

"It's definitely better than your rush to turn unrequited love into a so-called broken love. ”

"When the time comes, there will be a partner, and so will the university!"

After Fang Nian's words fell, all the classmates laughed, and some of them were very unimpressed, and finally asked.

"Doing math problems is doing math problems, what does it have to do with listening to your class?"

Fang Nian smiled: "This question is very good, then let me ask you, will you still do the first exercise of mathematics compulsory one?"

"Will you do it, raise your hand and let me see?"

There were very few people in the audience who raised their hands, most of them were still opening the book, and Fang Nian continued to speak.

"Don't want to run without learning to walk, you don't listen to me now, in addition to knowing 1+1=2, what else will you do, how do you fill a homework book?"

"You don't listen to me now, how do you know why I can get a perfect score in the test casually, and you can't even pass?"

"I don't embarrass you, and you don't embarrass me, it's still the same sentence, it's okay not to listen to the class, keep your mouth shut, and don't disturb others to study. ”

After a pause, Fang Nian said the last sentence.

"Don't be a person who has no object and hasn't been admitted to a good university at that time, I blame you when I think of today's events, do you think you can afford to take responsibility?"

Then Fang Nian straightened up, his face was solemn, and he shouted, "Go to class!"

"Stand up!"

Li Xue was excited, and shouted subconsciously.

In the classroom of class 174, most of the students stood up with Li Xue, and finally there were 65 people in the entire class-

Fang Nian was also standing.

It's just that few people say the word 'good teacher' next.

Fang Nian pressed his hands and said, "Please sit." ”

"From now on, I will start the class in earnest, and I will listen carefully if I want to listen. ”

"Do you understand?"

Everyone in the audience: "......"

You look at me, I look at you, but no one talks to me.

Fang Nian didn't care, glanced at the book a few times, his posture was calm, and he said in a relaxed tone: "The first thing we need to review is the assembly problem. ”

"We have all heard this thing many times, that the written word is a whole made up of one or more definite elements. ”

Fang Nian looked at the audience: "Actually, this thing is very simple. ”

"For example, this chalk box is a collection, and the pile of chalk of different sizes inside is the different elements in the collection. ”

"To put it more complicatedly, it is: you have me, I have you. ”

“......”

After a pause, Fang Nian looked at the audience: "Do you understand?"

The audience looked at each other again: "......"

This time, Fang Nian paused, and asked in an accentuated tone: "Don't be dumb, squeak." ”

As the squad leader, Li Xue hurriedly took the lead and said, "I understand!"

Because of the unusual start, most of the students in the audience, especially in the back row, still looked like they were watching the play with their arms in their arms.

They want to see how many of Fang Nian's first fifteen years old!

Fang Nian didn't care about this, as long as he didn't disturb his class, and he didn't disturb others to listen to the class.

"Attention, look at the blackboard!"

Fang Nian knocked on the blackboard.

"Who's going to answer that?"

"Okay, no one raised their hands, right, Li Xue, come on!"

Fang Nian didn't give everyone a chance to react at all, and said directly.

Li Xue stood up and said, "Subset ......"

“......”

The speed of Fang Nian's lecture was neither fast nor slow, and some of the students who were originally unconvinced and wanted to know how Fang Nian could dare to substitute for the class also couldn't help but follow the train of thought.

This time is not like the last time I gave a class to a few people such as Zhu Pengfei.

There are quite a few things written on the blackboard.

Although chalk board books are not as good as water pens, they are still enviable.

"What are you doing looking at the blackboard?"

"Look at me!"

Occasionally, Fang Nian would also accentuate his tone to remind everyone to concentrate.

“......”

Although Fang Nian's lecture was not fast, because it was a review, the first subsection of the first chapter ended quickly.

Fang Nian glanced at the book a few times: "The review of the questions of the collection is over here, if you don't understand, raise your hand." ”

No one in the classroom raised their hand.

On the one hand, some students don't want to show weakness, but on the other hand, they really understand.

Since there is no one, let's review the next knowledge point: functions. ”

"We learned functions when we were in junior high school. ”

"The three elements of independent variables, dependent variables, and correspondence laws sound a bit complicated. ”

When he said this, Fang Nian looked at the audience and knocked on the podium.

"What are you doing on the blackboard, reading a book!"

"We can see that the concept is not described in detail in the book. ”

"To give you a simple example that you like to hear, for example, if you like someone, and you tell him about it, and he is silent, so you are scared and quickly say let's be friends. ”

"This process is called a function, you change with him, he will also change because of you, the independent variable, the dependent variable, and the corresponding law are all in it. ”

"A simple example of a mathematical column is y=x+1, when x=1, y=2.

When x=-1, y is equal to 0, which is equivalent to nothing, as if you were friends in the first place, and after a lot of twists and turns, you finally returned to friends. ”

“......”

The first math lesson in Fang Nian's life to his classmates ended with the bell ringing at the end of class.

The overall atmosphere in the class was ok.

The students sitting in the front row still followed the train of thought in class.

There are also more than half of the back row with a cold attitude at first, but in the end they can't help but follow the train of thought.

After class, Fang Nian returned to his seat and hurriedly took two sips of water.

It doesn't matter if it's a substitute teacher or not, as long as you stand on the podium and give a lecture, you will definitely have a dry mouth and tired feet.

It's hard to be a teacher.

At least Fang Nian felt it now.

I don't feel like I can talk to people for about ten minutes once in a while, but I teach more than 60 people in a class......

Tut!

Li Annan came over and said, "Old Fang, I'll just say it, everyone can understand better in class." ”

"These examples alone are even more memorable. ”

He felt that the example Fang Nian gave at the beginning seemed to be aimed at him.

Fang Nian smiled and didn't answer.

How can it be possible to give a lecture to a class compared to one-on-one?

Every time he explained the problem to Li Annan, Fang Nian used some descriptors to make him understand better.

Not good for universality.

"Fang Nian, you have done a good job in this lesson, I feel that I have a thorough understanding of the basic aspects of sets and functions. ”

Li Xue, the squad leader, also came over and said.

"I originally wanted to see what you were capable of substitute teaching, but I didn't expect to follow a class. ”

"He is worthy of being a master who can get a full score in mathematics in 30 minutes!"

"I'm just curious about where Fang Nian saw these examples, vividly. ”

“......”

In the face of everyone's praise, Fang Nian, who had taken a class, was so tired that he just smiled and didn't want to squeak......
