Xueba: The Knowledge I Teach, The Crit Is Returned

There were 57 students in the third class of Yangcheng No. 1 Middle School, except for Liu Yanyan, all the other 57 had shock written on their faces.

As classmates, of course they know Liu Yanyan's math scores.

Liu Yanyan usually scores around 90 points in the monthly math test, and she can get more than 100 points at most, and will never exceed 110 points.

How could they not be shocked when they heard that Liu Yanyan scored 143 points in the test.

You know, this is mathematics, the most difficult subject in high school.

And how difficult it is to make progress in mathematics is well known to everyone.

From 50→90: Normal difficulty;

From 90→120: medium difficulty;

From 120→130: great difficulty;

From 130→140 or more: super hard.

Because with the higher the score, every 10 points of progress requires several times more effort, and even talent.

As for Liu Yanyan, she actually went from 90 points to less than 140 points.

So they will be surprised, will be shocked.

As Liu Yanyan's tablemate Wang Na, in addition to being shocked, her heart is also full of miscellaneous grains.

One moment, she was still mocking Liu Yanyan for believing in the online teaching, but the next moment Liu Yanyan scored 143 points in the exam and slapped her in the face.

On the stage, the voice of Zhang Bo, a math teacher in the third class of Yangcheng No. 1 Middle School, continued to come.

"Liu Yanyan, come up and get the test paper."

"Oh." Liu Yanyan nodded and walked towards the podium.

Talking about the test paper and handing it to Liu Yanyan, Zhang Bo smiled and praised: "You did well in the test, keep going, 985 and 211 universities are beckoning to you."

"Thank you teacher, I will continue to work hard." Liu Yanyan said happily.

After that, Zhang Bo looked at the other students in the class and said solemnly, "I said that you are all so stingy with your applause?"

"Liu Yanyan scored 143 points in the test. This is the result of her hard work. You can be envious, but not jealous."

The whole class was silent.

Indeed, as Zhang Bo said, many people have not only envy, but also a trace of jealousy in their hearts.

Grades, everyone wants to be higher.

"Teacher, is Liu Yanyan cheating? How can she improve so much? You know, she usually gets over 90 points in the exam at most."

However, at this moment, the voice of a classmate came from the class.

Immediately, the whole class was in an uproar.

After all, plagiarism is not a good thing.

In fact, more than one person in the class had the idea of ​​whether Liu Yanyan was plagiarizing, but... no one said it.

Because the third year of high school is almost an adult, everyone knows that whether the grades are good or not is their own, so what's the point of getting high scores by plagiarism?

"Yes, teacher, I also doubt it."

"It's only been less than a month, how could Liu Yanyan have improved so much."

Seeing that someone suspected Liu Yanyan of plagiarism, Wang Na also stood up at this time.

"I didn't, I didn't plagiarize." After hearing Wang Na's words, Liu Yanyan felt a little aggrieved.

I don't know if I cheated, others don't know, and my roommate doesn't know.

on stage.

Zhang Bo frowned, he said slowly: "Don't talk nonsense without evidence, and... the third question of the second-to-last question in this test paper, Liu Yanyan was the only one in our class to do it. come out."

"Liu Yanyan has made rapid progress. It can only be said that she has become enlightened and she has worked hard."

Hearing Teacher Zhang Bo defending herself, Liu Yanyan also took the initiative to say, "Mr. Zhang Bo, I didn't plagiarize. I have been studying in the live broadcast room of 'Douyin' these days. Every time I understand it all, and even draw inferences from it.”

"learn by analogy?"

"Yes, otherwise my grades wouldn't improve so fast."

Liu Yanyan knew that although the teacher defended herself, some people must still not believe it.

She herself felt astonished to this day.

But the truth is, she has improved so much.

"I said at the beginning that this anchor really has something, otherwise I wouldn't transfer money to him."

Liu Yanyan bit her lip and raised her voice, "If you still don't believe me, I can take a test paper now to prove myself."

Saying that, Liu Yanyan took the initiative to walk to the podium again. She looked at Teacher Zhang Bo and said, "Teacher, are there any new exam papers, the ones we haven't done before."

"Yes..." Zhang Bo paused and did not refuse.

In fact, he was also a little curious as to why Liu Yanyan had made such great progress.

I heard Liu Yanyan say it was because of a "Douyin" teaching anchor, he must not believe it.

But within a month, he improved from 90 points to 140 points. As a math teacher for more than ten years, he certainly knew the difficulty.

It can be said that it is almost impossible, unless .... extremely gifted mathematical genius.

Liu Yanyan took the test paper in Teacher Zhang Bo's hand and started counting on the blackboard.

"I just prepared this test paper for printing today. It was originally intended to be your homework."

Zhang Bo also distributed the new test papers to the whole class.

"Look at the quadrant for odd-even-change-even-unchanged symbols, choose a for this question."

"sin30 is equal to 1/2, so the spatial coordinates of this Cartesian coordinate system are (1, 3, 0.5)"

"..."

In front of the blackboard, Liu Yanyan was not slow in doing questions.

Seeing Liu Yanyan doing the test papers at a high speed on the stage, every student was silent.

At this time, everyone is quietly waiting for the final result.

Time passes by every minute....

It was not until the end of the evening self-study that there was a delay of 30 minutes before Liu Yanyan finished writing the test paper.

At this time, all the answers she wrote down on the blackboard were densely packed.

Seeing Liu Yanyan write down the last character, Zhang Bo was a little shocked and speechless.

half an hour.

He turned his head to look at everyone and said, "When Liu Yanyan was doing the question, I already got the answer right."

"This time, she scored 141 points, although it was 2 points lower than the last time, but ... this is enough to explain everything."

"Liu Yanyan didn't plagiarize or cheat, she relies on her strength."

Zhang Bo reached the ears of every student in the class with some excited voices.

After everyone heard Zhang Bo's announcement of Liu Yanyan's results this time, everyone's eyes widened in surprise.

Really, it's all true.

Liu Yanyan watched the live study, and her grades improved by a full 50 points.

"Come on... it's too good, Liu Yanyan's cow leather!"

"My God, please let me know the number of the live broadcast room. I want to watch the live broadcast study."

"Similarly, this special cat is a miracle."

"I also want to watch the live broadcast, I want to test Qingbei..."

Chaos, at this moment, the entire Yangcheng High School Class 3 fell into chaos.

At this point, no one suspected Liu Yanyan of cheating anymore, and their focus shifted from Liu Yanyan's "cheating" to the teaching in the live broadcast room.

Of course, there is one exception, that is Wang Na, Liu Yanyan's roommate.

At this time, her face turned pale, because the person Liu Yanyan shared in this live broadcast room was her.

Grades don't lie, and math doesn't lie.

Liu Yanyan proved it with her strength: that anchor is really in stock! ! !
