The English teachers are beautiful and gentle, but the teachers in other professional classes are basically old men in their fifties and sixties, and many of them even have gray hair.

These old professors are dressed casually, most of them are washed white and blue overalls, to be honest, in Zhong Yuemin's opinion, there is no temperament, and you can't recognize these professors from Qingda in another place, and they are almost the same as workers.

Perhaps because of the impact they have suffered in previous years, the professors are usually cautious in their words and deeds, and when they speak to the students, they are polite and humble.

But as soon as they arrived in class, their spirit was completely different, their backs were straight, their eyes were full of strong self-confidence, and they were kind to the students step by step.

Zhong Yuemin seemed to see that a door of knowledge had opened in front of him, and the professors turned into tour guides, pointing to various landscapes in the palace of knowledge, and telling their antecedents and consequences, interesting anecdotes.

As for the students, they also cherished this hard-won learning opportunity, paid attention, listened carefully, and kept writing notes.

But often, the professors still have to stop and tutor everyone in mathematics and physics in junior high and high school, otherwise the professional courses will not be understood.

In fact, at the beginning of the school year, the school also arranged make-up classes, but after all, the time is short, and there are still many students who enter relatively late, and the foundation is not solid enough.

Zhong Yuemin's only advantage is that he has experienced the tempering of the college entrance examination in later generations, has a sound knowledge system, and has a solid basic knowledge of mathematics, physics and chemistry.

But looking at the seriousness of his classmates' study, Zhong Yuemin did not dare to relax and devoted 200% of his energy to study.

The lecture notes used in the class are all improvised by the professors, the paper is very rough, and the handwriting on them is also handwritten, which is mimeographed by the method of engraving wax plates, rubbed with a hand of black ink.

There is a handout for each course, and compared with the board books on the blackboard, Zhong Yuemin understands that these are written out by the old professors of each course word by word.

Each handout has as little as 10,000 words and as many as 50,000 or 60,000 words. Not a single word is scribbled, there is not a single typo, and some chapters are even accompanied by icons.

Zhong Yuemin has read a lot of books, but he has never read such a handwritten textbook with detailed and comprehensive knowledge points, his heart is hot, and his nose is a little sour.

Many of these old professors have been treated unfairly before, but when the organization needs them and allows them to go to the podium, they disregard their previous suspicions and devote 100,000 points of enthusiasm to teaching students, as if they are full of vitality.

······

"Excuse me, who is Zhong Yuemin?" Professor Zhang, who teaches water conservancy, finished his lecture and prepared to send out the last test paper.

Zhong Yuemin, who was doing the question, raised his head and raised his hand and said, "It's me." ”

"Zhong Yuemin, please come to the stage. Professor Zhang looked at him and greeted, and then said to the others: "Students, in the last class, I gave you a test question, involving some physics questions, Zhong Yuemin got a full score, and the last question also wrote two solutions!"

Zhong Yuemin stood on the edge of the podium, and the students in the classroom exclaimed in surprise and applauded involuntarily, this time there was no rhythm from Zhang Jin and Liu Guoqiang, because they also opened their mouths in shock.

Many students in the last class of the test collapsed after the exam, there are too many questions that they can't do, and many people don't even read the last question, Zhong Yuemin actually wrote a good solution.

"How did Yuemin grow his brain?" Liu Guoqiang looked at Zhong Yuemin standing on the side of the podium, and asked helplessly.

Zhang Jindao: "The three of us eat and sleep together and go to class together, and Yuemin doesn't read longer than us, how can he get a full score in the exam, and we can't pass the exam?"

"How do you know we're failing? I'm sure I'll be able to get a few!" Liu Guoqiang said unconvinced.

"You pull it down, I saw it when you handed in the test papers in the last class, and you didn't do several major questions in the end, can you pass?" Zhang Jin snorted.

"Wait and see!"

Zhang Jin looked at Zhong Yuemin again, "I'd better study Zhong Yuemin's head! ”

Professor Zhang continued: "Other students failed the last test, they need to work harder, if you don't understand the problem, you can ask the teacher or Zhong Yuemin for advice!"

"Hey~" Liu Guoqiang sighed after hearing this, and even the other students sighed, their faces turned pale.

"Students, don't be discouraged, you are still young, you still have a lot of time to study and improve, don't be discouraged because of a failure in an exam. "In addition, on behalf of the university, I would like to announce that based on the good performance of Zhong Yuemin, he will be allowed to join the Sanmenxia Dam Reconstruction Project Working Group for internship. ”

Everyone looked at Zhong Yuemin with envy, but they had nothing to say, this guy is a pervert, he actually studied every course very well, everyone failed, he got a full score in the exam, it was really hated!

……

From the beginning of the plan to the establishment of the project to the final implementation of the Sanmenxia Dam, there have always been people who oppose it, and the most insistent opposition voice comes from Professor Wan Li.

Professor Wan Li believes that the Yellow River is mixed with a huge amount of sediment, and if the problem of soil erosion in the upper reaches is not properly controlled, the dam will accumulate a huge amount of sediment in the reservoir, which will not only fill the reservoir, but even inundate a large amount of land upstream, threatening the safety of the people in the upper reaches of the Yellow River.

At that time, when experts from all over the country were convened for discussion, many experts raised objections at first, but after the high-level set the tone, these experts died down one after another, but Professor Wan Li still insisted, constantly writing reports, and even writing letters to the high-level to state the pros and cons.

Under the proverb "the saint comes out, the Yellow River is clear", Professor Wanli's insistence is like a joke, and no one pays attention to it.

However, with the completion of the Sanmenxia Dam, all of Professor Wanli's fears have become a reality, and the original planning goals of the Sanmenxia Dam have all been frustrated, and it has become a huge threat to the upstream and downstream.

Do you think that Professor Wanli's prophecy came true, and those officials, experts, and scholars who proved his mistakes would treat him like a hero, and then admit his mistakes to him with tears in their eyes?

On the contrary, Professor Wan Li was spurned by them, slandered as a curse for the great cause of socialism, knocked to the ground, and stepped on ten thousand feet.

Zhong Yuemin learned some of this information on the Internet in his previous life, and after arriving in Sanmenxia, he kept hearing the private discussions of his classmates and teachers, and he had a better understanding of the entire cause and effect.

But when Zhong Yuemin reached the first dam on the Yellow River, he was still deeply shocked by this huge man-made structure, which was more than 300 meters high and more than 700 meters long.

Zhong Yuemin felt the insignificance of human beings in front of this behemoth, but when he thought that it was humans who built this dam, he felt the greatness of human beings.

Professor Zhang looked at Zhong Yuemin's stunned expression and asked with a smile, "Yuemin, how do you feel?"

"Big! It's really big!" Zhong Yuemin sighed.

"It's big, but you didn't expect this huge building to be riddled with holes!" Professor Zhang sighed.
