Xueba, I beg you to go and escort him quickly!

B. It is impossible for two objects to be stationary relative to the ribbon at the same time

It is impossible for CM to slip relative to the ribbon

It is impossible for Dm to slide upward relative to the slope

After writing this question, Qin Fangming felt alive again.

Yes!

He is very confident in this question!

The answer to this question is complicated, but he has the answer.

Looking at the students, Qin Fangming smiled, "Students..."

The story is not over yet!

Squeeze it!

A classmate stood up.

"Teacher, this question is easy!"

Jane... easy?

Qin Fangming just wanted to say it was difficult!

In the end, a classmate stood up and said it was simple?

And in his impression, his grades are still average, not very good.

???

Qin Fangming, "Come on! Tell me how to do this problem! Come on! Tell me! I'll give you the chalk!"

The classmate grinned.

"Teacher, then I'll tell you the truth..."

Qin Fangming had black lines on his face.

The student said, "We assume that the coefficient of friction u is infinite, and M and m stick to the silk, so B is wrong!"

"If the coefficient of friction u is infinite, M>m, M slides down, and m slides up, so D is also wrong!"

"Teacher, you sometimes have multiple choice questions for this question, so you choose AC, am I right?"

Qin Fangming, "!!!"

Quiet!

The classroom is extremely quiet at this time!

PS: There will be updates later!Continue to explode!Ask for all support! .

Chapter 101

The classmate easily answered the question in a few minutes.

Yes!

The answer is AC!

Qin Fangming was stunned.

He was just ready to listen to this classmate's so-called "simple" answer, and his mentality is still not stable~ Hold on, this is the end!

Even more critically...

What he said made sense!

Come on! ! !

Qin Fangming was speechless, he really panicked.

The problem-solving ideas used by my classmates are simpler and faster than my own.

"This, this... I... I'm fine! Sit down! Sit down!"

"Hey……"

Sigh!

Helpless!

Qin Fangming's spirit of just fighting is gone again now.

The students looked at Qin Fangming's decadent look, and felt relieved.

"Teacher, why don't you tell us about your problem-solving ideas?"

Qin Fangming is not stupid!

This method is so easy, why should it be difficult to talk about it!

Besides, wouldn't it be even more embarrassing for me to tell the difficult things?

Qin Fangming was stunned for several seconds, and asked, "Is this also what Xu Heng taught you?"

The crowd nodded.

Qin Fangming looked at Xu Heng, his eyes were full of doubt and incomprehension.

"Xu Heng, you...how did you know it! This, this, this..."

Xu Heng, "Eh... Teacher, it's actually very simple, isn't it? I will, are you surprised?"

"Shocked...shocked..."

Qin Fangming's forehead was throbbing with blue veins.

Surprised!

How could you not be surprised!

But Qin Fangming couldn't say it!

At this moment of stalemate and embarrassment, Yao Ruiyi knocked on the door of the class.

"Teacher Qin, I have something to do with Xu Heng."

Qin Fangming breathed a sigh of relief, "Go!"

Yao Ruiyi took Xu Heng away, and he had a step down.

Look at the group of students in the class.

One month!

Only a month has passed!

How could it have changed in Xu Heng's hands!

This is where the teacher is teaching the students, but the students are teaching the teacher!

Sin ah...

Qin Fangming looked at Xu Heng who wanted to leave through the window.

Mixed feelings.

Head teacher's office.

Yao Ruiyi, "Xu Heng, our school just received a call..."

Xu Heng said, "Teacher, don't be foolish, please tell me, what's the matter?"

Yao Ruiyi smiled.

"The Poetry Conference invites you!"

Poetry conference?

Xu Heng frowned, "If I remember correctly, it should be a TV show, right?"

"Yes! It seems that you are going to the capital again."

Xu Heng curled his lips, "Why did you invite me?"

Yao Ruiyi took a deep breath, "It's not what you think! You are definitely not invited to be a contestant! Other contestants sign up by themselves!"

Xu Heng, "Then let me be a judge?"

Yao Ruiyi nodded seriously.

Xu Heng, "!!!???"

real or fake?

Xu Heng himself couldn't believe it.

But he quickly calmed down and asked, "Professor Wu or Academician Qian recommended it?"

Xu Heng could only think of the two of them.

Yao Ruiyi shook her head, "I don't know about that! But after the phone call, the TV station asked for your opinion. If you nod, they will immediately arrange a car to pick you up."

Xu Heng, "Wait a minute! I'll make a call and ask."

In the teacher's office, holding the mobile phone swaggeringly, making a call.

Apart from Xu Heng, there is no one else!

Call Wu Liubai directly.

"Professor Wu, the invitation to the Poetry Conference..."

On the other end of the phone, Wu Liubai smiled happily, "I recommended it to them, because the old money also went, when they invited me, my work conflicted with the schedule of the program group, so I recommended you."

Xu Heng had black lines on his face, "Hey, hey! Professor Wu, I'm busy too, I..."

Wu Liubai revealed, "Student Xu Heng, yes, yes, you are very busy, but you just finished the exam, you better relax!"

"I happen to be in the capital too, so we can have a good get together after we come here."

Xu Heng, "..."

"Stop talking, I'm busy, bye."

This old man doesn't look like a good person!

What Qian Yuejiang couldn't say due to his status was all said by Wu Liubai.

Xu Heng frowned, "I always feel that this matter was discussed by the two old men."

As for whether Wu Liubai is okay or not, that is a question mark.

Xu Heng's current foreign language registration has been stranded, and he has not found a suitable place. The same is true for other subjects. They are all stranded. You might as well go there again.

Although there is no suitable place for Peking University, it does not mean that there is no place in the capital.

"Fine!"

Xu Heng nodded.

Yao Ruiyi immediately contacted the principal.

This matter was directly approached by the principal!

Oh no!

To be more precise, they found the province, the province found the city, and the city found Yunshan High School!

Just pay attention!

When the provinces and cities received the call, they were excited!

Just after the test, Xu Heng's full score in general subjects is not mixed with any water, and it still belongs to that incredible full score.

Now there is another invitation to the Poetry Conference.

"Go! Must go!"

"It's just surprising that the Poetry Conference will invite contestants on its own initiative!"
