[If AB=Y, BP=X, CE=Z, PC=YX can be obtained.

…………

That is, Z(YX)=X(YX), given that X=Z, we can get △ABP≌△PEF

Obtain PA=PF, get the proof. 】

Did it really work out?How is it possible, how is this possible!Director Xu was in a constant state of shock, looking at the paper full of answers.Wriggling his lips, he said after a while, "Didn't you watch it on the computer last night?"

After saying this, he immediately shook his head, wanting to test whether he could really complete it independently, so he just picked a set of papers and did it for him, wouldn't it be over?

"Ah?" Wang Yun was taken aback, "No, I thought about what you said just now, and then I started to do it."

"That's fine." Director Xu nodded, and looked a little more pleasant to Wang Yun, "I still have a geometry here, you can see if you can make it yourself." If Wang Yun can really make it, he firmly believes , Wang Yun is a genius.It's just that I didn't like reading in the past, and I didn't say that my intelligence was used in the right way.

"Okay." Wang Yun's hands started to itch when he heard Director Xu said that there was a problem to do.

Then Director Xu took out a paper, put it in front of Wang Yun, pointed to one of the geometry problems and said, "This is the problem, see if you can solve it."

[Assume that ABCD is a convex quadrilateral inscribed in a circle, and verify: AB?CD+AD?BC=AC?BD. 】

Wang Yun looked at the topic first, and then began to think about it.Director Xu took out a blank A4 paper, put it in front of Wang Yun and said, "No, use it for calculation."

"Thank you, Director." Wang Yun took the A4 paper and began to calculate.After a while, Director Xu was working, Wang Yun raised his head and said, "Director, I'm done."

"..." Director Xu was stunned, looked at Wang Yun and said, "So fast?"

"Okay, okay?" Wang Yun didn't know whether his speed was fast or slow, so he could only blink his eyes and looked at Director Xu with an inexplicable expression.

"Then, show me." Stretching out his hand, Wang Yun very consciously passed the answer he had written to Director Xu.

[Take a point E in BD, make ∠BCE=∠ACD, and get △BEC∽△ADC, you can get:

…………

From ①+②, it can be obtained: ABCD+ADBC=AC(BE+DE)=AC?BD, which is proved. 】

Really done, and still right.These are just the geometry problems in a paper he randomly picked up. It is impossible for Wang Yun to memorize all the geometry problems.What's more, I don't know if this geometry is available on the Internet.

Director Xu was shocked for a while, Wang Yun blinked his eyes and said to Director Xu, "Director Xu, Director Xu, are you okay?"

"No, it's nothing." Breathing out, Director Xu looked at Wang Yun and said, "You really haven't learned anything before?"

"Yes, yes." Wang Yun nodded, "But now it seems that learning is still very interesting."

"Oh?" Director Xu raised his eyebrows, "Why do you say that?"

"Because I overcome one difficulty after another, I think it's quite fun. It's like...well, playing a game, defeating one boss after another."

"Really?" Director Xu smiled and said, "Okay, I'm here to see how far you have reviewed your Chinese and English."

After all, Director Xu took out two papers for Wang Yun and said, "This is the question for their third-year exam. You do it. Let me see if you can finish one paper in two hours. .”

Holding the paper, Wang Yun nodded, "Don't worry, I can finish it."

As he spoke, Wang Yun picked up the pen and began to write on the blank test paper.

Director Xu looked at the paper Wang Yun gave him, and read it carefully.Shocked, utterly shocked, he never expected that Wang Yun did it with almost no mistakes.

Yes, there are still some mistakes and omissions, but these are some relatively subtle knowledge, probably because of self-study.Even if I have thoroughly understood the knowledge in the textbook, there are still some places where I did not listen to the teacher's explanation, so I made mistakes.

This is more proof that this guy really mastered almost all the knowledge points of junior high school in one night of self-study.

It is an unimaginable thing at all, and this guy has completed it.Turning his head and looking at Wang Yun who was doing the paper, Director Xu took a breath, thinking in his heart, this time he has found a treasure completely.Unexpectedly, the Ninth Middle School met such a genius. Given time, if Wang Yun didn't slack off, it is entirely possible to be admitted to Beijing University or Jinghua by virtue of his own ability.

In the decades since the establishment of the Ninth Middle School, there are still a few students admitted to 211 or 985.However, the highest institutions of learning such as Beijing University or Jinghua have never appeared.

Director Xu's heart began to beat wildly, he must be allowed to study hard, and he must not be allowed to slack off.

While thinking wildly, Wang Yun put the paper on Director Xu's desk and said, "Director, I have finished the English paper."

Director Xu raised his wrist to check the time. It was less than an hour, and he finished it?These questions were given by the teachers of the junior high school, and there are almost no such questions on the Internet.If Wang Yun can achieve 120 points in this set of questions, it can almost be said that he has thoroughly grasped the English knowledge points in junior high school.

The remaining [-] minutes are probably the sequelae of not listening to the teacher's lecture.It doesn't matter, you can make up for it later.

After looking at the densely packed papers, Director Xu said with satisfaction, "Put it here first, and finish the Chinese papers first. I'll go out for a while, remember not to turn the pages, and do the questions carefully."

"I know, sir, don't worry."

Director Xu walked out of the office with the paper, and he went straight to the junior high school.

At this time, almost all the teachers in the junior high school are in class, but after all, there are still some teachers who have no class.When he came to the classroom office in the third grade of junior high school, he walked to one of the English teachers and said, "Ms. Zou, can you help me correct this paper?"

Teacher Zou is a relatively young teacher. Seeing the dean of the high school approaching, he hurriedly stood up and said, "Director Xu?"

"No, it's this paper, how about you take a look for me?" Director Xu put the paper on Teacher Zou's desk.

Even though Teacher Zou was full of doubts, he couldn't ask.

He took the red pen and began to correct. After a while, Teacher Zou said with a confused face, "This paper is well done, but it's a bit weird."

"Oh?" Director Xu looked at the score, 135 points, a very high score.Compared with yesterday, Wang Yun only had a few points, almost a skyrocketing score.

"It's just..." Teacher Zou frowned and thought for a while, "How to describe it, it's as if I've never attended a class before."

"Why do you say that?" Director Xu looked at Mr. Zou and said suspiciously, "If you have never attended a class, why do you still have such a high score?"

Teacher Zou couldn't laugh or cry, "I don't know, but his test paper can indeed get such a high score. But there are some details. For example, look at this question, the teacher. It is a question that our teacher must explain. It is correct. The answer should be B, but he chose C. If there is no teacher explaining this question, and he reads the book by himself, he will naturally choose C. However, I still don’t understand it. If he didn’t listen carefully, how could he pass the test? This kind of score. These mistakes are actually places that shouldn’t be wrong. Even in class, you can’t make mistakes after listening for a while.”

Now Teacher Zou looked at Director Xu with a dazed expression, and Director Xu thought for a while and said, "Mr. Zou, do you think it is possible that the knowledge points in this set of papers are not comprehensive?"

"No, the knowledge points in this set of papers cover all the knowledge points in the entire three years of junior high school, and it is very comprehensive." Teacher Zou became curious. Director Xu is the dean of the senior high school, why came here with the junior high school papers In junior high school, this is a bit strange.

"Then Mr. Zou, tell me, is it possible that someone who has never read a book has mastered all the knowledge points of the entire junior high school overnight?"

"Impossible, absolutely impossible." Teacher Zou raised his voice and said, "If this is really possible, it is impossible for junior high school to study for three years. Unless..."

"Unless what?"

"Unless you're a genius, how could you have never read a book and learned all the knowledge of junior high school overnight?"

With that said, Mr. Zou finally came to his senses.He looked at Director Xu dully and said, "Director, you don't mean to say..."

Director Xu nodded, "I probably know." Holding the paper, he was about to go back, but Teacher Zou quit.He grabbed Director Xu and said, "Director, where did you say that student is, let me see?"

"Let's go, let's go." Director Xu glared at Teacher Zou, and he tore off the clothes that Teacher Zou was pulling, and said, "This is a student from our high school."

"Huh?" Teacher Zou was even more confused. A high school student was doing a junior high school paper.He looked at Director Xu in a daze, and after a while, he shook his head and sat down on the seat without saying a word, looking at Director Xu's receding back.He muttered and said, "It's strange, a high school student, how can I, a teacher from the junior high school, come to correct the papers."

Director Xu's heart is full of enthusiasm, he has found a treasure!Unexpectedly, I picked up the treasure by myself.

In just one night, he was able to learn all the knowledge points of junior high school, this memory, this self-study ability.Give him three years, if he doesn't get into Beijing University or Jinghua, Xu Deping will eat... Oh, forget it, all in all, this time he found a treasure.At the beginning, the headmaster strongly opposed it, but he relied on the mentality that if he could teach well, then he would teach, and if he could not teach well, then forget it.Unexpectedly, never expected... to be able to meet such a precious student.

Back in front of the office door, his heart was still beating violently, and it took a while before he calmed down.Pushing open the door, Director Xu looked at Wang Yun and said, "Good job, 135 points."

"Huh?" Wang Yun raised his head in confusion and looked at Director Xu.What 135 points?

"No, your paper." Director Xu put Teacher Zou's corrected paper on the table, and then said, "Don't be too complacent, this is just the knowledge points of junior high school. Besides, there are physics and chemistry that have not yet been tested. Woolen cloth."

"How about this, after finishing your Chinese papers, go home today and take a look at the physics and chemistry of junior high school. Tomorrow, I will take your physics and chemistry test. If you pass, then you can go directly to the first year of high school without a month. Attend class."

Wang Yun nodded vigorously and assured him, "Don't worry, I will definitely pass the exam." Last night's study gave Wang Yun great confidence.

Master Xu said pointingly, "Don't be too complacent, if you don't get a high score, then..."

"Don't worry, I won't let you down." Wang Yun cheerfully handed over the language paper to Director Xu, "It's just right, I've finished this paper, Director, can you take a look?"

Director Xu was taken aback for a moment, he just finished the paper after leaving for a while?This is a bit strange, "Well, you can put it here, I will watch it later. You go back first, you have passed the Chinese, English and mathematics, remember to watch physics and chemistry tonight, you know? "
