Liu Yichen put his schoolbag on his desk and wanted to take a shower.

Passing by Deng Lingze's desk, I saw Deng Lingze holding a pen and looking at a question with a sad face. This is the second question for answering a math paper, with a four-pyramid drawing, which obviously examines geometry knowledge.

"Liu Yichen, I can't do a question here. Can you help me?" Deng Lingze suddenly said, then was stunned and shook his head amused: "I'm so stupid. You have just entered the first year of high school. This question is the real question for this year's college entrance examination. How could you do it!"

Liu Yichen glanced at the title: "As shown in the figure, in the quadrilateral p-abcd, then the surface pad⊥ bottom abcd, side edge pa=pd=2^0.5, and the bottom abcd is a right-angle trapezoid, where bc∥ad, ab⊥ad, ad=2ab=2bc=2, o is the midpoint of ad. (1) Prove: po⊥ plane abcd; (2) Find the size of the angle formed by the linear line pb and cd in the opposite plane; (3) Does the point q exist on the line segment ad, so that the distance from it to the plane pcd is 3^0.5/2? Assuming that there is, find the value of aq/qd; assuming that it does not exist, please explain the reason."

Liu Yichen pondered for a moment, then said with a smile: "This question is not difficult!"

Under Deng Lingze's surprised eyes, Liu Yichen drew this quadrilateral on the draft paper and then wrote (1) proof: in △pad, pa=pd, o is the midpoint of ad, so po⊥ad, and the side pad⊥ bottom abcd, so po⊥ plane abcd.

(2) Connecting bo, in the right-angle trapezoid abcd, bc∥ad,ad=2ab=2bc, there is od∥bc, and od=bc, so the quadrilateral obcd is a parallelogram, so ob∥dc, from (1), we can see that po⊥ob,∠pbo is an acute angle, so ∠pbo is the angle formed by the straight line pb and cd on the opposite plane...

In Deng Lingze's stunned, Liu Yichen completed the answers to the three small questions in less than three minutes, and it seemed that nothing was wrong.

Liu Yichen took the changed clothes, soap, shower gel and shampoo and went to the bathroom, leaving only the stunned Deng Lingze.

After a while, Deng Lingze took the draft paper left by Liu Yichen, pushed his glasses, stared at the topic, frowned slightly, and fell into deep thought.

Now, Qingcheng No. 1 Middle School has completed the teaching of the entire high school knowledge points as early as the last stage of the second semester of the second year of high school. Except for some subjects, everyone else has begun to enter the first round of review. Before the college entrance examination, the entire high school third year needs to complete three rounds of review, and continue to further compress and refine according to the college entrance examination syllabus to strengthen students' training on test points and test questions.

So, when Liu Yichen wrote the answer to this question, Deng Lingze quickly understood the answering ideas and corresponding knowledge points.

But what he couldn't understand, how could Liu Yichen, a freshman in high school, have such deep knowledge?

And in such a short time...

Deng Lingze bit his lip.

Suddenly, Deng Lingze felt a little suspicious about his life. He studied hard in high school for two years and officially ushered in the countdown to the college entrance examination. As a result, he found that he seemed to be worse than a rookie who had just entered high school. How could he welcome the college entrance examination?

Is it...I am going to be over in the college entrance examination?

Deng Lingze thought of a terrible result, and for a moment, he felt that his life was a dark and bleak, hopeless future, and an extremely bleak road to the college entrance examination.

Wow~~~

Thinking of this, Deng Lingze couldn't help but howl and burst into tears.

Liu Yichen, who had just come out of the shower, saw Deng Lingze sitting on a chair, straightening his back, closing his eyes and howling loudly.

"There is no tears in this crying, it's too fake. At least you're crying!" Liu Yichen looked at Deng Lingze howling and cried, but unfortunately there was no tears in his heart. He thought speechlessly.

Liu Yichen didn't persuade him. He was used to his weird roommate. He wouldn't be used to not crying once a week. Sometimes he wondered when men liked to cry so much. Didn't it mean that men wouldn't cry easily?

Could it be that Deng Lingze is a...woman? Are you playing with a woman dressed as a man?

Liu Yichen was a little helpless and picked up the book he borrowed and started to look.

At around 10:50, Yang Hao and Yang Jie returned to the dormitory on time. Seeing Deng Lingze's eyes red and his sniffing constantly, they looked surprised.

What's going on?

It’s been weekends, why did Deng Lingze still cry? This is unscientific!

"Ling Ze, I'm a veteran. Let me tell you, the college entrance examination is just that. Don't worry too much, put too much pressure on yourself." Yang Jie said earnestly.

As a repeater, Yang Jie is not in the same teaching building as Deng Lingze. There are three classes of repeater students and their own separate classrooms. However, in the dormitory, Yang Jie is the oldest and experienced person, so he naturally became the principal.

"Son-in-law, you don't know... Liu Yichen is not a human?" Deng Lingze said.

Yang Hao and Yang Jie were both startled and looked at Liu Yichen who was reading and doing questions. It turned out that Liu Yichen was not a human being. No wonder someone was so handsome. It turned out to be a monster!

A bold monster, why don’t you show your true form quickly!

Just when the two were about to use the magical power of subduing demons and demons, Deng Lingze said: "Liu Yichen...he actually solved the real questions of this year's science college entrance examination! Look, this is something a rookie in the first year of high school can do, it is obviously a monster!"

"It hurts so much, and it makes me take the college entrance examination! I thought about it for three hours but couldn't come up with a solution. It took him less than 10 minutes!" Deng Lingze became sadder and howled and cried.

“…”

Yang Hao and Yang Jie almost fainted. Damn, please tell me if it’s okay? What does Liu Yichen mean?

However, they also looked at Liu Yichen in surprise. Since the beginning of school, the only thing they did was that the school organized them to do the 2006 college entrance examination real test paper. After turning it over, they all found that they were so frustrated.

They did not expect that Liu Yichen could actually answer the questions in the mathematics real question paper, which means that this junior brother is different!

When Liu Yichen saw three pairs of eyes looking at him in unison, he was a little puzzled. Isn’t it just to solve a problem? As for, one can continue to cry after crying for so long, and the two looked at themselves with this kind of eyes as soon as they came back?

Don’t you know that your roommates are forced to be academic masters? Can ordinary people understand the life of academic masters?

If you are forced to be a top student, you are also a top student. Can a top student be regarded as a top student?

In front of the top students, are all mortals a scumbag?

Alas, it is too difficult to explain the world of academic masters to mortals. Forget it, I won’t explain it anymore. I still want to travel around the sea of ​​topics. Only the sea of ​​learning is my own belonging and bring happiness to myself.

In the face of explanation or not, Liu Yichen decisively chose to be an arrogant novices.
Chapter completed!
