Xueba: The knowledge I teach, critical hits are returned

There are 57 students in Class 3 of Yangcheng No. 1 High School. Except for Liu Yanyan, the faces of the other 57 students are all full of shock.

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

Liu Yanyan's math scores in the monthly exams are usually around 90 points. If she performs well, she can only score more than 100 points at most, and will never exceed 110.

How can they not be shocked when they hear that Liu Yanyan scored 143 points?

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

And everyone knows how difficult it is to improve in math.

From 50→90: ordinary difficulty; from 90→120: medium difficulty; from 120→130

: extremely difficult; from 130→140 or above: super difficult.

Because as the score gets higher, every 10 points of improvement requires several times more effort, and even talent.

And Liu Yanyan, she didn't even get to the 140 level from 90 points.

That's why they were surprised and shocked.

As Liu Yanyan's deskmate Wang Na, in addition to being shocked, she also felt mixed emotions.

The previous moment, she was still mocking Liu Yanyan for being stupid enough to believe in online live teaching, and the next moment Liu Yanyan scored 143 points to slap her in the face.

On the stage, the voice of Zhang Bo, a math teacher in Class 3, Grade 3 of Yangcheng No. 1 Middle School, continued to be heard.

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

"Oh." Liu Yanyan nodded and walked towards the podium. After handing the test paper to Liu Yanyan, Zhang Bo smiled and praised her,"You did well. Keep up the good work. 985 and 211 universities are waving at you.""

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

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

"Liu Yanyan scored 143 points. This is the result of her hard work. You can envy her, but you can’t be jealous.

The whole class was silent.

It is true as Zhang Bo said that many people not only envy her, but also have a little jealousy in their hearts.

As for grades, everyone wants to have higher scores.

"Teacher, did Liu Yanyan cheat? How could she improve so much? You know, she usually only scores over 90 points."

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

Suddenly, the whole class was in an uproar.

After all, the word"plagiarism" is not a good thing.

In fact, there were more than one person in the class who thought that Liu Yanyan had plagiarized, but...No one said it out loud.

Because we are in the third year of high school and almost adults, everyone knows that whether the grades are good or not is up to you, so what is the point of getting high scores by cheating?

"Yes, teacher, I also doubt it."

"It's been less than a month, how could Liu Yanyan have made such great progress?"

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

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

Others didn't know whether she cheated or not, but didn't her deskmate know?

On the stage.

Zhang Bo frowned and said slowly:"Don't talk nonsense without evidence, and...Liu Yanyan was the only one in our class who could answer the third question of the penultimate number series question on this test paper."

"Liu Yanyan has made rapid progress. I can only say that she has gotten the hang of it and has worked hard."

Hearing Zhang Bo's defense, Liu Yanyan took the initiative to say,"Teacher Zhang Bo, I didn't plagiarize. I have been studying in the Douyin live broadcast room these days. The anchor explains the questions so well that I can understand them all every time and even apply them to other situations."

"learn by analogy?"

"Yes, otherwise my grades wouldn’t have improved so quickly."

Liu Yanyan knew that even though the teacher defended her, some people would still not believe her.

She herself still finds it unbelievable.

But that’s the fact. She has made such great progress.

"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 do a test paper now to prove myself."

As she said that, Liu Yanyan took the initiative to walk to the podium again. She looked at Teacher Zhang Bo and said,"Teacher, do you have a new test paper, the kind that we haven't done before?"

"have..."Zhang Bo paused but didn't refuse.

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

Just now, he heard Liu Yanyan say that it was because of a Douyin anchor who taught. He certainly didn't believe it.

But within a month, 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....A mathematical genius with great talent.

Liu Yanyan took the test paper from teacher Zhang Bo and started calculating on the blackboard.

"I just prepared this test paper today and printed it. I originally planned to use it as your homework.

Zhang Bo also distributed the new test paper to all the students in the class.

"The sign of odd-even change does not change. Look at the quadrant. For this question, choose a."

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

"......"

In front of the blackboard, Liu Yanyan was doing the test very quickly.

Seeing Liu Yanyan doing the test paper very quickly, every student was silent.

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

Time passed by minute by minute.....

It was not until the end of the evening self-study that Liu Yanyan finished writing the test paper, which was delayed for another 30 minutes.

At this time, the blackboard was already densely packed with her answers.

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

After a while, he turned his head and looked at everyone and said,"While Liu Yanyan was doing the questions, I had already checked the answers."

"This time, she scored 141 points.���The last time was 2 points lower, but...This is enough to explain everything"

"Liu Yanyan did not plagiarize or cheat. She relied on her own strength."

Zhang Bo's excited voice reached the ears of every student in the class.

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

Really, all of this is true.

Liu Yanyan watched the live broadcast to learn, and her grades improved by 50 points

"Depends...So awesome, Liu Yanyan is so awesome!"

"Oh my god, please tell me the live broadcast room number, I want to watch the live broadcast to learn"

"Likewise, this is a miracle."

"I also want to watch the live broadcast. I want to take the entrance exam to Tsinghua University and Peking University...."

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

At this moment, no one suspected Liu Yanyan of cheating, and their focus shifted from Liu Yanyan's"cheating" to the live teaching.

Of course, there was one exception, that was Liu Yanyan's deskmate Wang Na.

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

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

Liu Yanyan proved with her strength: that anchor really has the goods!!!.........................................
