Inside the classroom

When Lu Yuan walked to Lao Hu with the test paper, Lao Hu raised his head and pushed his eye sockets with two fingers together, glanced at Lu Yuan, and then smiled:

"Why are you so slow today, if you don't do it properly, I'm going to fix you. ”

Lu Yuan looked at Lao Hu like this, and couldn't help but say with an innocent face: "Teacher, you also know the state of my study. Although it was a slow time to do this time, I can guarantee that I really did it seriously. ”

Suddenly, the light curtain slowly appeared in front of me, and I saw that the light curtain had a quest for it.

"Ding!Quest Quest:

(1) Let the teacher impress you

(2) Let your classmates be impressed with you

Reward: 10 member growth points, talent identification skills (one probation period)

Bonus: Momentarily disappears the Forgetfulness skill

Oh hey, this quest is clearly to send me something, I have to say that the system is really fragrant, thank you to the system! Lu Yuan thought beautifully.

Of course, Hu Miyan was really skeptical of Lu Yuan's words, after all, Lu Yuan handed in the paper the fastest every time. He still remembered that when he finished correcting Lu Yuan's paper and combining it, he realized that although he had the speed of a scholar, he did not have the talent of a scholar.

I also remember that I have repeatedly discouraged Lu Yuan to treat every exam well and not pay attention to it anymore. But Lu Yuan, every time he is perfunctory, he does not only repent.

Finally one time, the school began to conduct a month-end test, but Lu Yuan, he was stunned directly in the seat of the examination room after he finished it.

This made the invigilator at that time not to mention how angry he was, and he almost scolded him for saying that the shaft could not be carved.

After a long, long time in the past, this incident was gradually forgotten by Lao Hu.

But now, when this matter came back to his mind, Lao Hu felt the urge to scold him again.

Lao Hu said that he was also very helpless about this, who called him Lu Yuan my student! After all, he was not Lu Yuan.

Zuo Laohu: Phew, don't scold him, who is it, is it himself?

Right Lao Hu: What am I doing? Although I am very angry, I am a teacher.

Calm~

I must be calm~

Call~~

Hu Miyan, who spat out, looked at Lu Yuan again and said in a suspicious tone, "Really?"

Lu Yuan looked at Lao Hu's disbelieving expression, and he knew that after experiencing the last incident, Lao Hu's impression of him was a little bad.

"It's true, it's more real than gold!" Lu Yuan said with a resolute face.

Lao Hu glanced at him again, was silent for a moment, and then sighed: "Okay, since you are so insistent, then I will believe you again." ”

Then his gaze turned to Lu Yuan, and when he saw that Lu Yuan was stunned with a resolute face, he didn't know what he was thinking, and he couldn't help but say angrily: "What else are you looking at?

"Ah, oh, oh. ”

When Lu Yuan handed the test paper in his hand to Lao Hu, Lao Hu began to write hard.

looked at it, only to see it on Lu Yuan's test paper

The first question, √

The second question, √

…

Question 5? Yes.

How is this possible?

Hu Miyan's heart was a little shocked at this time.

It shouldn't be, Lu Yuan is not so smart in his usual life, and he will get it wrong after doing a few questions correctly, but how did he get it right today?

Could it be that he copied someone else's? But he knew better than anyone else what was going on with the students in his neighborhood.

Could it be that Lu Yuan is really a genius? But, I didn't notice that he was very smart before!

Is it that he is about to take the college entrance examination? In the past, he didn't know how to pay attention to it, but now, he knows how to pay attention to it? Only then did he begin to show his intelligence?

…

Yes, it must be.

Thinking of this, Lao Hu continued to bury his head in changing the topic.

Lu Yuan never dreamed that Lao Hu had already arranged a reason for him, and he didn't have to think hard about how to answer Lao Hu's words.

But Lu Yuan didn't know that at this time, he was meditating and thinking: If Lao Hu asked him a question like you did it yourself, how would he answer.

Just as he continued to be stunned, Lao Hu began to change the question again.

Question 17: In the known sequence {an}, a2=2a1=2... (2) Find the first n terms of the sequence {Cn} and Sn.

…

(2) From (1) bn=1*2n-1=2n-1.

Because Cn=1/2(2n+1)(2n-1)

…

=1/4（1-1/2n+1）

=n/4n+2

，√

…

When the scores were combined, Lu Yuan was a little shocked, after all, he had never scored such a high score. At this time, Lao Hu was directly dumbfounded, after all, even if Lu Yuan started to accumulate a lot from today, it would be very good to be able to take the 100 test, but Lu Yuan scored 147 points, this score is very incredible, and people can't believe its authenticity.

So, Lao Hu raised his head to look at Lu Yuan, and asked in a trembling voice, "This... The test paper is you... Do it yourself... Is it?"

The sudden trembling voice made the students who had already begun to prepare to leave wonder.

"What's going on?"

"It's weird, it's weird! Today's old Hu is so strange. ”

"It's incredible, it's incredible, Lao Hu actually asked Lu Yuan. ”

…

At this time, the classroom, which was already noisy, began to become noisier. Slowly, the students began to come over in confusion. But when the top student Zhang Qingcheng also came over, this surprised Lu Yuan. After all, he never remembered that this scholar had a habit of joining in the fun.

"That's right, I did it myself. My classmates around me know that I made this paper myself. Lu Yuan looked at Lao Hu's expression and said helplessly, "I don't believe you ask." ”

At this moment, some of the classmates around Lu Yuan couldn't help but say, "Teacher, Lu Yuan's roll was made by himself."

"Yes, yes. We're all watching."

"That's right, teacher. Lu Yuan's test paper was made by himself, and we can testify to it. ”

…

After hearing the students' answers, Lao Hu groaned for a while, and then said to Lu Yuan: "Congratulations! ”

Lao Hu's sudden words made the originally noisy classroom instantly quiet, and then became even more noisy.

I saw that the students in the classroom were shocked and began to discuss, "Good grades?

"Lu Yuan also got a good score in the exam, how good is it, and I don't know what kind of level he usually has?"

"Then tell me why Mr. Hu praised Lu Yuan so much and asked him?"

…

Even Zhang Qingcheng, a school bully, began to look at Lu Yuan in shock + confusion after listening to the conversation of his classmates.

At this time, Lao Hu smiled happily: "This time, Lu Yuan played super long, and his score was only 2 points higher than Zhang Qingcheng this time. ”

In fact, Lao Hu thought like this in his heart:

Hahaha, I was shocked at first, I didn't believe it was the truth, but the result was the truth. Now, you're starting to taste the shock, and I'm happy to think about it.

As soon as these words came out, the students present were shocked again, and they all began to speak one after another: "WC, is it really fake?"

"Nonsense, Teacher Hu has said it, how can there be a fake? What's more, Lu Yuan really didn't copy it."

"666, I don't support the wall now, I only serve Lu Yuan."

"Yes, yes, so do I. ”

…

When Zhang Tingcheng heard the teacher's words, she was a little incredulous, and even very angry. Subsequently, she was also puzzled, because she didn't know why Lu Yuan did this.

Was it just jealousy, vanity, or something else? She couldn't figure it out, and she began to hate Lu Yuan a little.

However, when she heard the conversation of her classmates, she suddenly changed her opinion of Lu Yuan.

I don't know if it's because she's thinking too focused, or whatever, that hate lingers.

At this time, what she thought in her mind was:

How did Lu Yuan do it?

How did he learn?

…

But she didn't know that Lu Yuan was a systematic man.
