Xueba God-level system

After experiencing the explosion of the mobile phone, Zhang Guilin did not feel ashamed at all. Instead, he felt that what he did was very honorable. It was only a matter of the principal personally awarding him the trophy for outstanding young teachers.

"Whew!" Wang Binghui exhaled viciously, "I'm so mad. If he didn't pay attention when he went to answer the phone just now, I would bend down and sneak out from the The back door slipped out. I don’t know when the next opportunity will appear.”

Then, I saw Wang Binghui use the heel part of his sneakers to gently rub the back door open slowly.

The only advantage of doing this slowly and meticulously is that the iron door will not make any sound when it is rotated open.

Just like that, Wang Binghui, who was closest to the door in the last row, started his kung fu of rubbing the door.

Going down with one foot, it is not a problem to rub it open 5 degrees. If you rub it too much, you may make a "squeaky" sound, just like the sound of the door opening in the middle of the night in horror movies, even worse.

"I rub left and right, up and down." Unknowingly, Wang Binghui began to hum, and a smile appeared on the corner of his mouth, that kind of smile that was too bad.

At the same time, Mr. Zhang was not idle here. He used all his life's strength, picked up a brand new chalk, stood on tiptoe, and challenged the height of life.

With his height of about 1 meters, it is a bit insignificant to reach a large blackboard that is more than two meters high.

But he didn't want to give up this rare opportunity at all, the time of his life had already passed, and it was not too short of a few seconds.

It's just to simply draw a monotonically increasing interval without losing a piece of meat.It can not only improve students' ability to understand mathematics, but also establish a tall and straight image of themselves in the minds of students. Why not do it!

Now, he is over 35 years old.When a person reaches middle age, the hurdles that should be passed have been passed, and many heights have been crossed, and he is afraid that this small blackboard will fail.

With his own encouragement, as a teacher, he became a little more presumptuous.

In fact, in his heart, he had already made a budget in advance.He is now 1 meters tall, standing on tiptoe to raise 55 centimeters, and then the length of a complete piece of chalk is about 10 centimeters.

Someone may ask, 10 centimeters plus 6 centimeters, this is only 16 centimeters in total, plus his height, it is enough to reach a height of 1.7 meters.

The difference between this and the two-meter-high blackboard is not a star and a half, but it is 29 centimeters. For Mr. Zhang, it is absolutely impossible to challenge the height of life.

Could it be that he could still jump up and write?Although jumping up can make up for the 29 cm gap, this is a palace of books and a home for learning, not a monkey juggler in a circus.

Just imagine, what kind of scene is it like for the students to sit at the bottom and watch the teacher jumping up and down on the podium.

For these students from impoverished mountainous areas, it is not easy for their parents to earn money for them to study. The hard-earned money is for them to study and study, not to watch the teacher take off.

In fact, the length of 29 centimeters can be completely made up for if Teacher Zhang stretches his arms.
