When Wang Xianchao heard this, his face turned blue and purple for a while. I want to say something, but I don’t know what to say.
Gu Xu was very calm and sneered: "Haha, why, I'm speechless!"
I can't even outplay you with your tricks, so my life has been in vain!
Wang Xianchao thought for a moment: "Then why didn't you say anything?"
Gu Xu said disdainfully: "I said it, but you didn't hear it."
"When did you say that!" Wang Xianchao was confused, "Why didn't I hear it?"
"I want to give you a report? Do you have to hear it for it to count?"
Wang Xianchao became angry instantly: "Not only did I not hear it, Teacher Zhang definitely didn't hear it either. If you don't believe me, ask Teacher Zhang."
"It's normal that Teacher Zhang didn't hear. She was so far away from me. Besides, she didn't ask me specifically. She asked all the classmates. It's normal that she couldn't hear."
Wang Xianchao still wanted to say something, but felt that he didn't know what to say.
Gu Xu scoffed disdainfully: "Are you upset because I said I understood? I understand. It's just a small probability event. You don't have to feel ashamed if you don't understand. Questions like this require the ability to imagine multi-dimensional space." , maybe your imagination..."
"What do you mean!" Wang Xianchao's face was full of anger.
"I don't mean anything!" Gu Xu said coldly.
Zhang Song turned around and rolled his eyes at Wang Xianchao and sneered: "Idiot! If you can't understand such simple words, how did you get second place in the exam? You must be confused!"
Gu Xu also smiled. Zhang Song's ability to fight others has improved a lot now.
Wang Xianchao narrowed his eyes subconsciously, and Gu Xu and Zhang Song laughed at him at the same time.
He was even more dissatisfied and filled with anger.
"Teacher Zhang!" Wang Xianchao suddenly said loudly, "Gu Xu said that he understood and was willing to teach everyone how to solve this problem. He said that his idea is better than yours."
Lan Ruosi looked unhappy: "When did Gu Xu say that? Why didn't I know?"
She hurriedly said loudly: "Teacher, Gu Xu didn't say it, Wang Xianchao said it himself."
Gu Xu felt a warm current in his heart. At this time, his wife would take the initiative to stand up and speak for her.
Wang Xianchao smiled coldly: "Classmate Lan, your words are obviously protecting Gu Xu."
"I didn't!" Lan Ruosi emphasized, "You are just talking nonsense."
Wang Xianchao looked at Gu Xu: "Gu Xu, you just said it yourself, you understand!"
Gu Xu answered: "Yes, I said it, I understand! How about it!"
What Wang Xianchao said didn't count, and neither did what Lan Ruosi said.
When Zhang Xiaoli heard Gu Xu admit it personally, she was shocked. Gu Xu actually understood!
Wang Xianchao continued: "It was you who told Lan Ruosi just now that your idea might be better than hers!"
"Yes! I said it." Gu Xu did not deny it.
Wang Xianchao said angrily: "Then Lan Ruosi's thinking is the teacher's thinking. You just said that your thinking is better than hers, doesn't it mean that your thinking is better than the teacher's?"
"Haha!" Gu Xu smiled lightly, "What a quote out of context."
Zhang Xiaoli was even more surprised when she heard this: Gu Xu actually had other ideas?
"Gu Xu, since you understand, come up and tell your classmates how to do it!" Zhang Xiaoli said.
She really wanted to see what Gu Xu was thinking.
Gu Xu's academic performance has improved a lot recently, and he even took the first place in the grade in Chinese composition. Maybe he really has other ideas.
If he really understands it and has other ideas, he can really be called a dark horse.
"Okay!" Gu Xu agreed and looked at Wang Xianchao at the same time.
"Teacher Zhang, Wang Xianchao said he can do it too, and his ideas are better than mine!" Gu Xuye said hurriedly.
hehe!
Such people must not be lenient!
Who hasn’t watched "Dragon"?
Do you think you are the only one who can do what Murong Fu said in return?
Are you playing with me? Don't I want to play dirty for you?
Zhang Xiaoli was shocked: "Did Wang Xianchao do it too?"
She was instantly overjoyed: "I originally thought that not a single classmate would know how to solve such a problem, but now two classmates know how to solve it. Come on, come on, you guys can do it."
Wang Xianchao looked embarrassed: "Teacher, what should I do if there is no blackboard here?"
He couldn't say no, and he couldn't not do it, so he immediately found other reasons.
Zhang Xiaoli said: "It doesn't matter! There is a screen projection here. You and Gu Xu each take a piece of paper and do it below. I will cast the screen for you so that everyone can see it. After you finish it, tell everyone."
The more she talked, the more excited she became, and she really wanted to see what the students did.
Gu Xu agreed: "Okay, this is a good idea! Teacher, please arrange it!"
Zhang Xiaoli asked Gu Xu and Wang Xianchao to come up. This kind of large staircase classroom has a large podium, and there is more than enough room for two people to go up. Gu Xu sat on the left side of the podium, Wang Xianchao sat on the right, and Zhang Xiaoli sat in the middle.
Gu Xu took the paper and drew two parallel lines on it...
Wang Xianchao looked at the projection with a pen. The picture drawn by Zhang Xiaoli was so complicated that he couldn't tell which line started from the beginning, so he had to try his best to imitate it.
The people present looked at them and commented one after another.
"Gu Xu draws the line very clearly."
"I have no idea what Wang Xianchao is painting."
"Gu Xu's picture seems to be different from the teacher's."
Zhang Xiaoli looked at the two people's ideas for solving the problem. Gu Xu was very clear and seemed to have grasped the core.
Wang Xianchao was painting here and there for a while. Zhang Xiaoli saw that he was imitating herself, but the painting became blurry and blurred.
"Teacher, I've finished the painting!" Gu Xu said.
Zhang Xiaoli said: "Then tell everyone!"
Gu Xu nodded: "When we do this type of problem, we must clearly remember the initial conditions. We cannot see the first projection and the Nth projection on the screen.
Because we only live in three-dimensional space.
After multiple projections, maybe this geometry is not the geometry we know. After each projection, we must remember it clearly, and then, after multiple mappings, expand outward again and again. "
Lan Ruosi blurted out: "I understand!"
After Gu Xu said this, she finally understood. It turned out that the extension was not once, but many times.
Zhang Xiaoli nodded and looked at Wang Xianchao: "Wang Xianchao, if you can't do it, go down first!"
"Teacher, I can!" Wang Xianchao was unconvinced.
"Then tell me what you did!" Zhang Xiaoli said.
"I..." Wang Xianchao hesitated for a moment, "I need to think again."
Gu Xu laughed: "You can't do it, why waste other people's time."
Wang Xianchao retorted: "Do you think that someone understood what you just said? It was just a few random words, who wouldn't?"
Wang Xianchao said and looked at everyone: "Do you understand?"
Everyone shook their heads.
Lan Ruosi answered: "I understand!"
"It doesn't count if you understand!" Wang Xianchao shot back.
"Why doesn't she understand?" Gu Xu asked back.
"She has a good relationship with you, maybe she said that on purpose."
"You're talking nonsense, I understand!" Lan Ruosi retorted.
Wang Xianchao added: "Unless you can make more than 80% of the people in the class understand, then you really understand."
Zhang Xiaoli's heart skipped a beat. She couldn't guarantee that 80% of people would understand.
"Why should I prove to you that I understand?" Gu Xu asked back.
"Because you're just talking nonsense."
Zhang Xiaoli interrupted: "Gu Xu, I think you really understand. Please analyze your experience for everyone. Wang Xianchao, please go back first!"
