The old man shook his fluffy and explosive hair, stood aside, and said, "Boy, if you don't sing well, you will continue to be punished." ”

Song Jian nodded, thought for a while, and said, "Then let's have a song of Master Li's favorite lyrics, Juvenile You, for everyone." ”

"Huh? Who is Master Li? Isn't the juvenile tour sung by Ren Xianqi? ”

"Stupid you, Master Li is the first beauty of the Song Dynasty, but what kind of young tour, is it Song Ci?"

"What is this guy pretending to be?"

The students below buzzed into the conversation.

Song Jian ignored it, coughed, and sang: "And the knife is like water, Wu Yan wins the snow, and the slender hand breaks the new orange." At the beginning of the brocade temperature, the beast fragrance continues, and the relative sits on the sheng.

Whisper and ask: To whom do you stay? There have been three shifts in the city, and the horses are slippery and frosty, so it is better to take a break, and there are few people. ”

The word is a good word, this "Youth Tour" is filled in by the great writer Zhou Bangyan of the Song Dynasty, although it is a work of vinegar, but the love for the beauty is still overflowing with words, through the paper.

Song Jian had the honor to listen to the female singers in the palace sing this song, and this time he sang it, which was also a special taste.

The old professor on the side nodded his head involuntarily, his fingers gently joined with Song Jian's voice, and his fluffy and erect white hair shook with his head.

After singing the song, the old professor raised his hand and applauded: "Good! It seems that you have a lot of research on Song Ci. Boy, it's really good to sing. ”

Song Jian smiled slightly, but the students in the classroom disagreed.

"What are you singing about?"

"I don't understand the words."

"Yes, yes, miserable, teacher, this can't be passed."

These rich second generations and official second generations at the bottom are making a fuss, these days, those who learn this major are all rich second generations who don't learn and don't know how to do it, and they come here to mix diplomas. Naturally, they couldn't understand what Song Jian was singing.

However, these people did not understand, and one person outside the classroom was extremely shocked.

Zhou Tong is a third-year student in the Department of Journalism of Gusu University, and the first class is her professional class, because she got up late, so Zhou Tong is only in a hurry to walk to the classroom now.

At this time, an antique song of Song lyrics suddenly came from the classroom next to him, Juvenile You.

Zhou Tong is very fond of Tang and Song Dynasty culture, and has studied it for a long time, and when she heard this song "Youth Tour" at this moment, she was stupid.

"It turns out that Song Ci is sung like this, and it is really beautiful." After listening to this, Zhou Tong felt that her heart was agitated, and she couldn't help but look over, wanting to see who was humming.

With his head slightly tilted, his right hand brushed the bangs on his forehead, and through the window, Zhou Tong looked towards classroom 203.

At this glance, the satchel in Zhou Tong's left hand fell to the ground with a "bang", and I saw that the person standing on the podium was the life-saving benefactor he had been looking for for in the past month, Song Jian!

"It turns out that he is also a student of Gusu University," Zhou Tong stood in place like this, with an excited and happy smile on his face.

More than a month ago, in Jinbi Brilliant, Zhou Tong was boyfriend and girlfriend with Li Jian of the school basketball team at that time, Li Jian saw that he couldn't take Zhou Tong for a long time, so he took advantage of the KTV party to drug Zhou Tong's wine.

Zhou Tong was taken into the women's toilet by Li Jian in a daze, and just when he was about to lose his innocence, it was Song Jian who suddenly appeared and saved himself.

After leaving from Jin Bi Huang last time, Zhou Tong has been looking for Song Jian, wanting to repay him and thank him for his rescue, but for more than a month, Zhou Tong has not been able to see Song Jian again.

Zhou Tong leaned on the window edge and stood stupidly in the corridor, staring intently at Song Jian on the podium in the classroom.

Hearing that the students below were making a fuss, the old professor said helplessly: "Boy, look, it's not that I don't let you go, it's that this group of students is dissatisfied." ”

Song Jian said: "Okay, then I'll be ugly again, let's have a song "Hotel California". ”

This classic old song is a masterpiece completed by the Eagle Band in the best state and the best combination, and it is a diamond-level golden song full of weird and moving melodies, just looking at the lyrics, a few strokes, almost all the sadness and confusion of the 70s of the last century are swept away. Until now, people who play rock and roll can't avoid this English song.

Song Jian has been in the United States for more than ten years, and he is very familiar with English, and he is even more familiar with this song.

As soon as the song was sung, there was a burst of applause in the classroom.

"Good!"

"Damn, this kid is a singer!"

"Damn, the limelight has been stolen by this kid from nowhere today, you look at the class flowers in our class, your eyes are straight!" A fat man with a Rolex muttered dissatisfiedly, but his eyes looked straight at Charlene.

There are mostly boys and only five girls in this major, and Charlene naturally became the most beautiful of the five. In fact, Charlene's eyes were indeed straight at this moment, because she never thought that her cousin's driver's uncle, Song Jian, could sing English songs, and she sang very well!

Song Jian arched his hand and said, "Since they are all satisfied, then I will go down." ”

The old professor nodded and said, "Well, well, it's not bad, boy, huh?" Is this your homework? Let me see. ”

As he spoke, the old professor had already opened the high math textbook beside Song Jian and pulled out the homework inside.

Song Jian rubbed his nose, sighed in his heart, and said secretly, "Hey, didn't I just come to deliver a homework?" How troublesome wave after wave. ”

Sure enough, just by looking at it, the old professor was already furious, and the white hair on his head swelled even more, as if he had been subjected to an electric shock.

"That's your homework! Is this your attitude towards learning! Are you doing a question or sleepwalking! If you look at your problem-solving process, can you figure out the relationship between calculus and addition, subtraction, multiplication, and division! ”

The old man is really popular this time, as an academician of the Chinese Academy of Sciences, Taishan Beidou in the mathematics world, he can't see his students the most to deal with himself, and now, seeing the problem-solving process on the homework paper, the old professor feels that Song Jian is ruining mathematics and insulting himself.

Seeing that the old professor suddenly became angry with Song Jian, the boys in the classroom snickered and gloated. And Xia Lin shrank her head and trembled, for fear that Song Jian would confess herself, in that case, it would be too embarrassing.

Zhou Tong, who was outside the classroom, also bit his delicate little lip nervously, worried about Song Jian.

Song Jian glanced at Xia Lin, and when he saw Xia Lin's pitiful eyes, Song Jian had no choice but to stiffen his scalp and said, "Teacher, don't be angry, in fact, ...... Actually, I'm trying to find a new way to solve this problem. ”

"A new approach? The new method you are talking about is addition, subtraction, multiplication and division? The old professor said angrily, and the teaching rod in his hand was ready to fall on Song Jian's head at any time.

Song Jian sighed in his heart and said secretly: Anyway, things are already like this, just be free and easy.

Thinking of this, Song Jian's whole body was relaxed, and he no longer concealed his edge, he picked up a piece of chalk on the lectern and said, "Teacher, in fact, I am indeed trying to solve this problem with a new method, you see, this question is like this......"

Song Jian said as he turned around and wrote on the blackboard in a chic manner, "Here...... In fact, according to the limit of thinking, zero can be substituted here, so this problem is simplified, so ......"

Saying that, Song Jian wrote quickly, and in just one minute, Song Jian had already come up with a result, and it was a very correct result. You must know that Song Jian's predecessor was a graduate student in chemistry at the University of California, although he failed to get his graduation certificate and degree certificate because of drug abuse, but for the undergraduate advanced mathematics of Huaxia University, Song Jian was able to catch it.

Xia Lin's eyes widened, and she looked at Song Jian on the podium incredulously, where was Song Jian still a driver uncle at this time, and he was obviously a knowledgeable young professor.

The old professor was also stunned for a moment, and then said: "Well, the result is correct, but you are playing tricks, in this problem, the limit is directly substituted for zero, which is true, but what if you change the topic?" ”

Song Jian picked up the advanced mathematics textbook on the table, shook it, and said, "Teacher, I think the important thing in learning this course is not to solve specific mathematical problems, but to master the thinking to solve problems!" Calculus, derivatives, itself is used to train students to look at problems and think, so that students can master the limit of thinking, and should not let students stick to these complex formulas, that is too rigid, and today's computer computing ability is much stronger, if you really want to solve mathematical problems, you can turn to computers. ”

After speaking, Song Jian picked up the high math textbook and homework, turned around in a chic manner, walked to Xia Lin's position, and sat down.

The old professor stood on the podium in a daze, and at this moment, he suddenly felt that a certain belief he had been pursuing for a long time was shaken by Song Jian. The old professor likes that kind of universal formula, because he thinks that those formulas contain human truths, so those formulas can solve all human problems. And Song Jian's words made the old professor less confident, and he suddenly understood that indeed, thinking is more important than method, and it is much more important!

The old professor bowed his head blankly, looked at his lesson plan, and was silent.

The students in the classroom were talking one after another, how could they ever see an arrogant and domineering student like Song Jian, who directly stunned an academician of the Academy of Sciences and was silent.

In fact, this is not because Song Jian's attainments in mathematics are really high, but because of the cultural differences between the East and the West.

Sitting down, Song Jian pushed all the high math textbooks and homework to Xia Lin, and said in a low voice: "I said Miss Xia Lin, next time there is such a dangerous thing, don't look for me, I am cowardly, I can't stand the toss, you know, I didn't study well when I was a child, and I trembled when I saw the teacher." ”

Xia Lin tilted her head sideways, looking at Song Jian with a pair of big eyes.

"Hey, Charlene, Charlene, you know this handsome guy, introduce me quickly," a woman to Charlene's right shook Charlene's shoulders and spoke. The woman was dressed very maturely, and although she had light makeup on her face, she still couldn't hide a few red beans next to her cheeks, but this woman's breasts were really plump.

He ...... He's the driver's uncle who came to deliver my homework, Song Jian," Xia Lin turned her head and whispered to the woman, "It's not a handsome guy, Du Hong, you nymphomaniac, don't make a mess." ”

"Uncle Driver? Charlene, do your drivers know calculus? Du Hong opened his mouth in astonishment, and the big steamed bun on his chest shook for a while.

Xia Lin finally reacted, she also turned her head sharply, glared at Song Jian, and her little hand had already choked Song Jian's neck, "Say it quickly, uncle, how can you calculus!" ”
