"Students, I will tell you about the progress of the last class and tell you about the concept of reaction heat."

"When a chemical reaction is carried out at a certain temperature, the heat released or absorbed by the reaction is called the thermal effect of the reaction at that temperature, referred to as the heat of reaction. It is represented by the symbol Q. ”

Mr. King of the Mediterranean, chattering from the podium.

It's really a chemistry lesson.

Good night seems to be taking this note seriously, but in fact, the sleepy bug in the head has been endless.

I couldn't lift my eyelids soon.

....

"Then good night, good night to answer this question."

A neutral voice sounded.

Pull goodnight back from the drowsy world.

Ms. Wang especially likes to pump her to answer questions, but fortunately she is used to it.

Imprint a little sleepiness.

Stand up and glance at the medium-difficulty examples on the whiteboard.

Reiki's eyes flickered, "B"

blurted out in an instant, and the voice was soft and soft.

The bald man on the podium nodded with satisfaction.

Good night is one of his favorite students in the 20 years he has been teaching.

When he first took this rocket class before, he used one college entrance examination chemistry question as an entrance exam.

I didn't expect the little girl to come out in 3 minutes.

When he checked, she stared straight at her. Eyes flickering.

He thought this kid was spiritual.

Later, I learned that he was a "practitioner". Playing the piano.

All of them have won international awards.

He had also seen the video of the little girl playing.

In the huge auditorium, the audience was full of people. The battle was terrifying.

But people are not flustered at all, and it is perfect from the stage to the curtain call.

I heard that Goodnight is still a little idol of several teachers in the school. It is said that her eyes are bright, as if they are full of clear stars.

He is also a good seedling in learning.

It is said that he is smart in music, he didn't believe it before, a Shen Yiyan, a little idol good night, really refreshed his cognition.

But the office is not in the right atmosphere.

Some young female teachers claim to be Shen Yiyan's "sister fans".

There is a miasma of black smoke, and there is no teacher at all.

It's not the same time now....
