The boy who was pulled by the arm had a question mark on his face?

"Who, you, there's something wrong." The boy pulled out his arm, glanced at Shi Ke, and hurriedly left, not a classmate, and didn't know Shi Ke at all.

Shi Ke found that he had saved the wrong person, and he also grabbed a boy's arm, embarrassed and very faceless, around, as if someone smiled lightly, as if he was laughing at her, Shi Ke bit his lower lip, lowered his head, and found the seating area arranged by his class with an aggrieved expression.

"She has been very safe since the beginning of school." There was already a trace of impatience between Lu Shi'an Junya's eyebrows, and he was already disgusted with Shi Ke.

keeps destroying, keeps pretending to be pitiful, it's obviously her own fault, but she still thinks that everyone is wrong, only she is right.

glanced in the direction of the third and fourth classes of high school, and asked Shi Ning, "Need ......"

"No, you don't." Shi Ning didn't wait for him to finish, and interrupted with a smile, "Let her stay at Shi's house and cause a little trouble to Cheng Sitong's mother and daughter." ”

Shi Ke has the skills to trouble people, and it is okay to let her stay in the Shi family to add to the blockage of Cheng Sitong's mother and daughter. In the past, the two mothers and daughters did everything to Xiao Ning, and she currently has no chance to find it back for Xiao Ning, so let Shi Ke find the trouble of the two mothers and daughters first.

All the classes in the third year of high school entered the auditorium, and there were still three minutes before the class time, and the three of them did not communicate again, walked to the stage, and sat down in their seats.

All the students in the first class sat on the stage, the high platform, the bright light, so that all the students in the audience can see and see clearly, in order to let all the students hear clearly, the Education Bureau also came to a set of imported audio equipment to keep it clear and free of noise.

And Lu Zhi'an didn't know that she had no intention of glancing at the third or fourth class of high school just now, which made Shi Ke happy, she felt that Lu Zhi'an was looking for her.

Alone in the seat, smiling secretly, full of joy, smiling and smiling, and was very embarrassed to glance at the table quickly, his eyes were sticky and spitting, and he was tightly entangled with Lu Zhi'an.

When the class bell rang, Principal Guan and He Ju were the first to come in, and Teacher Liu walked calmly and calmly to the stage as if he had walked into a classroom.

On the stage, Teacher Liu started class, everything in the class was as usual, there was no difference, the students were still a little restrained at first, after all, hundreds of people in the audience were staring, and it was normal to be a little scared and apprehensive.

But after five minutes, Mr. Liu opened up his ideas and brought all the students into the learning state in a rhythmic manner, and the students in the first class seemed to have forgotten to look at them with hundreds of pairs of eyes when they got off the stage.

Below, a teacher from another school wrote down: "Thinking, rhythm control, the whole class quickly entered the study." ”

"Throwing bricks and leading jade, sending out easy points first, and then turning difficult points, driving students' thinking."

I have to say that Mr. Liu's teaching method is quite clever!

……

Teachers from other schools watched the usual class mode of a class, and at the same time, they were also learning from Mr. Liu's teaching method, and it was obvious that Mr. Liu's teaching method was recognized by the whole class, and all the students' attention was concentrated in five minutes.

"Sequence of known points...... A3 is the midpoint of the line segment A1A2, and A4 is the midpoint of the line segment A3A4...... Write...... Relation to Xx-2 (n≥3). Let ax=...... Calculate a1, a2, a2 and infer the number series...... And prove it, five minutes...... Whoever proves first, and who stands up to parse the proof process. ”
