Back in the 1990s, she became rich through scientific research

Li Xin was called by the teacher to help her classmates. Her little face wrinkled, but she still agreed, "Teacher, I can do it. Hong Fei, if you don't understand anything, you can ask me. You haven't been here for a semester. I don't know." My grades have improved a few points."

Although Qin Hongfei didn't have a good impression of her family dog, seeing her active and willing to help Yun, it seemed to outsiders that she hadn't come back for a semester. In fact, she had returned to the classroom after more than twenty years. , don't tell me... there may be a lot of things that need help.

He accepted it gladly, "Thank you."

This exchange was quite enjoyable.

The first class was about homework. Qin Hongfei had no homework, so she familiarized herself with the knowledge in the new textbook. From a doctorate to a junior high school, it would be a bit hypocritical to say that she still remembered the knowledge in the textbook. .

My parents who have long been forgotten are all gone, but it doesn’t matter if I forget them all, I can still remember them if I memorize them.

Even if you can't remember the knowledge points, it's no problem to interpret it for yourself.

Qin Hongfei familiarized herself with the several textbooks she had received, and suddenly had a good idea in her mind. Fortunately, all the memory points were still there. If they were missing, she could make up for them. It was enough to use.

There would be no problem if I promised the old lady ninety points.

After flipping through the pages, she saw an equation and paused. This question...

Li Xin had been looking at her and knew that she didn't study in the last semester. She must have a lot of things she didn't understand and needed help. Thinking of the teacher's instructions, she said a little arrogantly, "What's wrong? I need to help you with what you don't understand." Can I lend you my homework? Let me tell you, if the teacher hadn’t asked me to lend it to you, I wouldn’t have borrowed it from you, and no one else would have borrowed it. My grades are all excellent!” she said in a proud tone.

Qin Hongfei really needed help, and Li Xin was willing to help, so she asked without hesitation, "Well, there is something I don't understand. How did you solve this equation?"

Li Xin looked at it and saw a chemical equation.

The teacher taught it last semester, but because it was said to be taught by the teacher in the second half of the semester, he didn’t talk much about it.

Ribose is an essential substance for human life. It is known that ribose... After browsing the questions, Li Xin suddenly felt like a student who finished writing the test paper during every exam. He was confident that his test paper would get full marks, "This question The teacher said it, I remember it, let me do the math..."

Qin Hongfei was immediately interested and looked at her calculations.

Other students were bored and joined in. There were many people, and Li Xin had more face. She explained the equations and solved the answers in a few moments. She instantly received sighs and praises from other students, which made her feel proud. , and showed it directly to Qin Hongfei, waiting for her adoring eyes and praise.

Qin Hongfei was also looking forward to it, but when she saw the final answer, she was speechless. She really shouldn't have had great hopes for her classmate, who walks her dog without leash. Seeing that other students were suspected of being misled, In line with the friendliness of her classmates, she said quietly, "Li Xin, your answer is wrong."

"How is that possible?" Li Xin retorted without thinking, "I remember everything the teacher taught last semester, and you didn't come last semester. You didn't learn anything at that time. How do you know it's wrong?"

She thinks she is right and does not accept refutation.

Qin Hongfei said because I know the answer to this question is, "C5H10O5."

The answer to this kind of question should not be too simple to calculate, but her problem-solving thinking is straightforward, and junior high school knowledge requires an equation. Qin Hongfei asked for advice just to know the equation, so as not to write down the answer. It meets the junior high school problem-solving standards. If you lose points because of it, then the gain outweighs the gain.
