"Huhai University is allowed to listen, but not all cats and dogs can come in. You brought a migrant worker, and he can't understand it. What can you do besides messing up the classroom?" A girl said sarcastically. Admirer, Ye Fei hurt Wu Haomin this morning, she was grieving.
Qin Xiaomeng's eyes widened, and he said angrily: "Who said he is a migrant worker!"
A girl said, "Well, even if it is not a migrant worker, it is necessary to attend an audit at our university. It is necessary to hold a hearing. Do you ask him?"
Qin Xiaomeng didn't speak for a moment, she forgot, the school does have rules for hearings, but no one usually checks this thing at all.
Even some students openly spend money and invite outsiders to attend classes for themselves. No one said anything.
However, the regulations are the regulations. Qin Xiaomeng does not know how to explain to Ye Fei now, but can only whisper: "Ye Fei, have you heard the hearing?"
Ye Fei shook his head and didn't expect that he wanted to listen to a class at the university, which was so difficult.
"Forget it, I'll go out now!"
Ye Fei sighed, preparing to stand outside the classroom and wait. At this time, the old professor on the podium spoke:
"Do n’t quarrel, this classmate wants to listen, this is good. Learning is endless, no matter if you have a foundation before, if you want to learn to listen, this is not wrong. However, if you really do n’t understand , I still do n’t recommend that you waste time here. Time is precious, youth is priceless. Do n’t waste time on this matter. As for the hearing, just wait for another one after class. Well, please take it In the textbook, today we are going to talk about a more difficult formula. Everyone pay attention to it. If you ca n’t hear clearly, you can raise your hand and ask me. "
Qin Xiaomeng was relieved, and sat down and whispered: "Fortunately it was Professor Nie's class, others are super good! Academics are also good."
Ye Fei nodded and sat upright, listening carefully to Professor Nie's lecture in front.
Professor Nie is also well-known in the academic circles at home and abroad. The class is indeed very good and easy to understand. I talked about it in the front and analyzed the formula from beginning to end. It was basically broken and crumpled. The talk was very exciting.
However, today ’s class was really difficult. After listening for a while, the students felt that their brains were not enough. However, none of them raised their hands and said they did n’t understand. , Whispered in a low voice: "It sits upright, just like a primary school student, can you understand? I don't understand if there is a fart!"
Ye Fei was completely deaf, he didn't go to school very much, so he cherishes this hard-won learning opportunity.
Today ’s course is indeed too difficult. Even Qin Xiaomeng, who is a good student, was impatient today after listening to it for a while. He touched Ye Fei quietly and saw Ye Fei ignored him. Blackboard, completely empty yourself, the soul does not know where to fly away.
This high-level lesson is a big one. It takes an hour and a half. Prof. Nie talked about these two formulas, and it took an hour. The blackboard was filled with dense calculations.
He found a classmate to help him erase the blackboard. It was too early to write two practice questions on the blackboard and said to the students: "You should understand the formula, now let ’s do two Consolidate the questions. These two questions have a certain degree of difficulty. If you ca n’t solve them, there is nothing. But if you solve them, you can get extra credits. "
Professor Nie raised the roster in Yang's hand, indicating that he was not talking.
As soon as the credits were heard, everyone's eyes were bright, and they hurriedly looked at the questions on the blackboard. Most people were dumbfounded. They didn't say these two questions, they didn't even understand them.
There were only a few scholars in the class. After watching it for a long time, I began to slowly carry out a pen on the paper. Both of them wanted to solve these two problems. The competition is average.
Among them is Qin Xiaomeng, but she has a small class today, so she has no way to start. She looks back at Du Wenxing. He seems to have some clues, and he is holding a pen and writing something on the paper quickly.
Feeling the eyes of others, Du Wenxing suddenly raised his head and saw that Qin Xiaomeng was looking at herself, and hurriedly put her arm in front of the paper to prevent her from seeing what she was writing.
"Che, who really thinks I'm peeking at your answer?"
Qin Xiaomeng snorted snortedly, with disgust in his eyes. Du Wenxing, a man with a small family, would not like it in her life.
Qin Xiaomeng did not really look at Du Wenxing, she just remembered that Lin Qingwan was sitting behind the classroom.
At noon, Qin Xiaomeng passed by the Academic Affairs Office and took a look at it, knowing that this beautiful sister was a high-quality student transferred from the famous Ivy League school in the United States, and had graduated with an undergraduate degree, and the other people in the class were just fresh Just one thing, she will definitely do it.
In fact, not only Qin Xiaomeng looked at Lin Qingwan, but some other students also heard some news and turned to see Lin Qingwan.
At the moment, Lin Qingwan's eyebrows were slightly wrinkled, her hands were still embraced, and she didn't mean to write a question. When you saw the students looking at themselves, they snorted coldly and rolled their eyes up, as if it were the topic Too simple, she didn't bother to do it.
In fact, Lin Qingwan is secretly crying in her heart now.
She has long heard that domestic mathematics is much harder than in the United States.
Lin Qingwan also thinks that she has a good brain, and domestic mathematics can't fail her.
Seeing today, she knew.
The domestic mathematics is more than difficult, it is simply abnormal.
She studied at the famous Ivy League school in the United States and graduated with a four-year undergraduate degree. When she returned to China, she didn't actually do the freshman class exercises. If you know, you have to laugh.
At the same time, Lin Qingwan's tragedy found that he wanted to pass the make-up exam in the country, I was afraid that it would be difficult to go to the sky.
Qin Xiaomeng glanced back and found that Ye Fei did not write, but kept staring at the two questions on the blackboard, it seemed to be in a daze.
It's no wonder that Ye Fei didn't even go to junior high school and asked him to do a problem that two college students can't understand.
Twenty minutes later, Du Wenxing suddenly raised his hands and stood up first, saying, "Professor, is the answer to the first question 3?"
"Oh Wenxing, you figured it out, it's really good!"
Professor Nie smiled and said, "The answer to the first question is indeed 3. It seems that you have already figured out this formula, and you can already go to the postgraduate level at your level. I have already guessed this question. Solve it, it must be you! "
"Oh, this formula is actually not complicated, and the topic is very simple, but it takes a little bit of brains."
Du Wenxing's modest expression of beating, looked back and glanced at Ye Fei and Qin Xiaomeng, and said: "I think this kind of problem can be solved by most students in the class. If it can't be solved, ... Haha, that is a problem with intelligence. "
