Even though Lin Yujing was very uncomfortable, Yu Hong's appreciation did not stop.

"Lin Yujing, you don't have to be embarrassed, the teacher's words are not exaggerated at all. ”

"This time, let's talk about the monthly exam papers, and also change the method. ”

Lin Yujing, who got a full score, will explain to you. ”

"I hope you'll listen. ”

"Especially for students who have worked hard but have poor grades, try to see if you can get any inspiration. ”

Yu Hong said, let go, and raised his hand to invite Lin Yujing to come to the stage.

Lin Yujing lectures?

It's a lively day off work.

Lin Yujing shook her head vigorously.

Seeing this, Jiang Qinghua took the lead in applauding: "Come on, Yu Jing, the teacher has let you go." ”

The students also applauded.

"Seek God's teaching. ”

"The future professor of the chemistry department of Jida University is here!"

Even Liu Xin applauded wildly.

It's over if it's good-looking, what does Guan Ya say?

Seeing Lin Yujing's shrunken appearance, Li Zheng snorted and smiled.

He knew Lin Yujing.

Impossible.

It is impossible for this kind of person to share his own learning ideas.

Sure enough, Lin Yujing half-covered her face and raised her hand and said, "Teacher Yu...... I have an uncomfortable throat......"

"Ah, yes......" Yu Hong re-entered the stage with some disappointment, "then next time." ”

The classmates were also disappointed.

I'm going to listen to the repetition again.

Only Jiang Qinghua's expression lit up, and he lowered his head and took the risk of pulling out his mobile phone to start operating.

Yu Hong began to talk about the topic.

Li Zheng also laid out the rolls and listened to them one by one.

After studying for more than 20 hours in a row, this paper now seems to be no longer worth mentioning.

Looking at his own mistakes, he even blushed, as if he was looking at a retarded person.

While the teacher is lecturing on the questions, he is also redoing the questions that he has done wrong, and writing the answers he understands now on the side to test the learning results.

Most of the mistakes were corrected by Li Zheng almost as soon as they were swept, even if it was just a normal learning rate, it would only take a few minutes to correct all the mistakes.

He felt a smoothness that he had never felt before.

It's not the clarity of thinking like physics and mathematics, but the fluency of Chinese and English.

It's hard to describe this kind of integration in words.

It turned out that it was all accumulating for so long.

At this time, it can be regarded as barely touching the chemical threshold.

Even so, he still didn't fully understand the seventh question.

It just so happened that Yu Hong also talked about this.

Let's look at the seventh question, which is the only question that Liu Xin has been corrected, and it will be sent to the sub-question. ”

"The following statements are incorrect—"

[A, sucrose, fructose and maltose, all disaccharides. 】”

"As soon as I came up, I learned that fructose is a simple sugar, so A's statement is wrong, so choose A. ”

"Because it's a multiple-choice question, in order to save time during the exam, B, C, and D don't need to be read at all. ”

"But here, we still have to say it. ”

[B, enzymes are a class of proteins with catalytic properties. 】

"This narrative is correct, not to mention, it is in the textbook. ”

Different crops have different pH ranges for optimal growth. 】”

"Even if you don't read the textbook, common sense should know that this is right. ”

"D, industrial electroplating has certain requirements for the pH of the electroplating solution. 】”

"I'm afraid that you won't be able to get the points for nothing, and I deliberately came up with option D that everyone knows is fine,"

"A certain classmate has lived up to expectations. ”

To sum up, B, C, and D are completely correct, and A is obviously wrong, so A is chosen. ”

In the midst of laughter, Liu Xin scratched his head again.

It's hard to get it right, can this be targeted?

"But!" Yu Hong suddenly changed his words and turned to look at Li Zheng, "There is a classmate in our class who has always worked hard, but he gave a funny answer. Li Zheng, say it yourself, what did you fill in?"

“A、B。 Li Zheng replied.

"You're really amazing, you've been doing papers for more than a year, don't you know if it's a multiple-choice question?"

"With your answer, I really don't know what you've been working so. ”

Sparse laughter rang out.

Liu Yue craned her neck to see the joke from a distance.

"Teacher, Li Zheng has memorized all the books. ”

All of a sudden, there was a lot of discussion.

Occasionally, some people showed a look of superior intelligence.

"It's still not okay to learn by death. ”

"Li Zheng is stupid, and he has come out with multiple choices......"

"I didn't even study, I got this question right haha. ”

Being looked at like this by the whole class.

Li Zheng is okay.

I don't want to be ...... by Lin Yujing

He couldn't help but crook his eyes secretly and observe.

It's strange, such a good opportunity, Lin Yujing didn't taunt.

On the contrary, she ignored Li Zheng at all and was nervously flipping through the book.

On the podium, Yu Hong sighed again and again.

"Hey...... Do I want you to memorize it?"

"Understanding, the key is understanding. ”

"Li Zheng, you ask Lin Yujing, did she carry it?"

"Tell me, where do chemistry books say that enzymes aren't proteins?"

"I didn't say it. Li Zheng nodded, "The description on page 81 of the textbook is that 'enzymes are a special class of proteins and important catalysts in living organisms. ’”

"You see, although you have bad eyes, you have a good memory. Yu Hong raised his head and asked, "It's all written in the book, why do you still choose B?"

"Because the narrative in the chemistry book conflicts with the narrative in the biology book of the first year of high school. Li Zheng explained, "Chemistry books say that enzymes are a class of proteins, but biology books say that most enzymes are proteins, and a few are RNA. ”

"It took a lot of effort for me to get on Wikipedia. ”

"Upon investigation, the Wikipedia narrative matches the biology textbook. ”

"I was afraid that there would be omissions, so I clicked on more entries to confirm it repeatedly. ”

Cech discovered ribozymes in 1981 and won the Nobel Prize in 1989. ”

In addition, mainstream articles on Zhihu and Zhiwang also make it clear that enzymes may also be RNA. ”

Other new editions of chemistry textbooks use the same statement. ”

So far, it is basically confirmed that the description of this version of the chemistry textbook selected by our school is wrong. ”

After that, I wrote an email and sent it to the Education Press. ”

"I hope that other students will not have to waste time because of this incident. ”

"So, option B, the enzyme is a protein, is a false statement, and the correct statement would be 'most enzymes are proteins'. ”

"To sum up, I choose A and B. ”

Li Zheng finished speaking.

The atmosphere in the class gradually became strange.

Silent.

Cold.

And "Hmm." ”

Lin Yujing held the textbook and stared at Li Zheng with her mouth slightly open.

This time, not a mockery.

It turned out to be respect.

Seeing that her expression was so reverent.

Li Zheng also bowed to her.

Although we have contradictions in many places.

But in the face of knowledge, our faith is unique.

Lin Yujing did not accept Li Zheng's kindness.

Instead, he gritted his teeth and glared at his own roll instead.

Nervous.

Panicked.

Li Zheng couldn't help but shake his head.

I'm going to forgive you for the stairs.

You're still like that.

Don't look at you anymore.
