A week later, Lin Yao started school.

The winter vacation lasted only more than 20 days, but Lin Yao, who returned to school, had a feeling that she had not been seen for a long time.

As usual, she parked her car downstairs in the Haida Building and walked briskly towards the University of Technology.

The straight-line distance from the Haida Building to the teaching building where she attended classes was only 500 meters, and she had to walk more than a kilometer in total to make a detour, and people would lower their car windows to greet her from time to time.

Lin Yao had just walked outside the north gate, and another car stopped next to her, Zhang Hu, who was full of flesh and flesh, greeted in a heroic tone: "Lin Yao! ”

Lin Yao beckoned to him with a smile, "Zhang Hu, good morning!" ”

Zhang Hu raised his chin at her with a smile and warmly invited, "Get in the car, I'll give you a ride!" ”

Lin Yao smiled, "I'm at the school gate, just a little way, I'll just walk over." ”

Zhang Hu insisted: "From here to the classroom, let's talk for five minutes, get on the bus!" ”

Lin Yao was shocked, it was only five minutes away, was it necessary?

Lin Yao finally couldn't resist Zhang Hu and took his car to the teaching building.

"How fast do you see this?" Zhang Hu's tone was not without pride, "Why don't I wait for you downstairs in Haida Building every day in the future and bring you over?" ”

Lin Yao was stunned for a moment, and said in her heart, then she might as well drive directly to school.

Lin Yao parked her car downstairs in the Hai Mansion because the school ended early, and she could go to the company every day after school.

Moreover, there are a lot of cars in the University of Technology, and vehicles have to queue up to enter and exit the school gate, the driving speed of vehicles on campus is slow, and it takes time for cars to find parking spaces in the school.

Zhang Hu took her on this journey, and the time was not much faster than walking.

No matter what, she still sincerely expressed her gratitude to Zhang Hu, "Thank you!" But don't bother, it won't take me much time to walk from Haida Building! ”

Zhang Hu insisted: "I didn't go there to pick you up on purpose, anyway, I passed by Haida Building every day, by the way, what are you doing with me so politely?" ”

Lin Yao said: "It's only been about ten minutes since I came over there, so it's time to exercise." ”

"Exercising?" Zhang Hu's face changed, his eyes were shocked, he didn't seem to expect this possibility, "It turns out that you specially parked the car over there." ”

Lin Yao tugged at the corners of her mouth, otherwise......

On the way to the classroom, Lin Yao received smiles from her classmates from time to time, and she obviously felt that the classmates were more enthusiastic than last semester.

This is partly because the news of her company has spread widely among the alumni community, and on the other hand, because of her outstanding academic performance.

Lin Yao was admitted to the University of Technology with the third overall score, but at that time, Cui Chenyi and Mu Wenxi's brilliance was too prosperous, so that most classmates only regarded her as a small transparent and even a small follower around Cui Chenyi and Mu Wenxi, and did not really take her seriously.

It wasn't until the end of a semester that everyone finally found out that Lin Yao and Cui Chenyi's grades were almost equal, and occasionally they could surpass Cui Chenyi, and the three of them had a bit of sympathy for each other, and the relationship was very iron!

Of course, that's what others think.

More than half of Lin Yao's courses this semester are the same as Mu Wenxi's, they are almost inseparable, and Cui Chenyi has alienated them intentionally or unintentionally.

On the podium, the professor was mild-mannered, and after a brief introduction to himself, he quickly began the class.

In today's course, we will briefly describe the history of the emergence and development of international trade, and briefly summarize and analyze the development of trade in different historical stages.

As early as 3500 BC, human civilization began to emerge in the Middle East. At that time, the rest of the world was still relatively backward, and the Middle East, which was located between the three continents of Asia, Africa and Europe, was already relatively developed......"

The professor talks about major historical events over thousands of years and their impact on the global economy.

Lin Yao listened with great interest, while Mu Wenxi was a little absent-minded.

After class, Mu Wenxi was puzzled: "Before, I met Cui Chenyi in the corridor and asked him to have lunch together, but he actually ignored me, turned around and left!" Alas, I can't figure out how I offended him. ”

Cui Chenyi is a bit gossip and a little naïve in his bones, but his idol burden is a bit heavy, and he has always been relatively cold in front of people, so it is not surprising that he would do this kind of thing.

Mu Wenxi smiled at everyone, and she was so beautiful, no matter whether she was a man or a woman, she couldn't refuse the invitation to eat with her, but Cui Chenyi refused, and she refused in public, it was normal for her to be unable to accept it for a while.

However, Cui Chenyi ate with them last semester, and there was a reason for his sudden change.

Lin Yao thought for a while and said apologetically: "Actually, I blame me for this, during the winter vacation, I asked him for help, and he probably annoyed me, don't worry, it has nothing to do with you!" ”

Mu Wenxi couldn't believe it: "Wow, when is this?" Why didn't I know at all, and you didn't look for me for something, but asked him for help? ”

Lin Yao thought of the night a week ago, when she went to find Cui Chenyi and was bumped into by his neighbor and misunderstood, the more she thought about it, the more embarrassed she felt.

You can't say that, but you can't say nothing.

She whispered: "Once a friend of mine moved, and I didn't know many boys in Hangzhou, so I asked Cui Chenyi to help out...... Anyway, it's my fault. ”

Lin Yao asked Cui Chenyi to move, and she was helping her friend move......

If he hadn't known that Lin Yao had a boyfriend and Cui Chenyi had a girlfriend, Mu Wenxi would have misunderstood that they had a great relationship!

Lin Yao also realized that something was wrong, and quickly explained: "I just asked him to make up a number, and I also found someone else, of course, he must not be willing to help with this kind of favor, so he will lose his face." ”

Mu Wenxi looked at her seriously, and said with heartfelt emotion: "I can't see that you guys have such a good relationship." ”

Lin Yao's eyes widened in shock, "I don't talk to him for more than three sentences?" How can you have a good relationship? ”

Mu Wenxi pursed her lips and smiled, silent.

Lin Yao almost swore to the sky, "At least it's not as good as you say!" ”

Mu Wenxi didn't hold on to this matter, and after a while, the professor walked onto the podium again.

"Let's start by recalling the classical trade model described in the previous lesson, assuming that country A has 120 laborers and country B has 50 laborers, if cotton is produced, the per capita production of country A is 2 tons, and country B is also 2 tons; If rice were to be produced, the per capita production in country A would be 10 tonnes and in country B it would be 15 tonnes. Analysis: Which of the two countries has the absolute advantage in producing rice? Which country has a comparative advantage in rice production? ”

This should be considered an introductory type of question, and it is designed to help students understand the impact of international trade on the economy of a trading country.

The class discussed international trade in an ideal state, which means that there are many prerequisites: the technical conditions of production are established and the benefits of scale are constant; The aggregate supply of factors of production is fixed; Factors of production can flow freely......

Either point is impossible to achieve in real life, so theory is just theory, and there is a huge difference between practice.

For example, Lin Yao's actual work is only engaged in the production of mechanical parts, and perhaps it will be imported in the future. But in essence, the impact of her and her company's trading behavior on the development of the regional economy is minimal.

But trade barriers between countries for a variety of reasons can often be devastating for small companies like Excellence.

From this point of view, it is of practical significance to study these theories and take some countermeasures in advance.

Lin Yao was full of thoughts here, and her classmates had already begun to answer the teacher's questions.

Fang Wei's voice was loud and replied, "Country B." ”

"Why?"

"Country B can produce 16 tons of rice per person, while country A only produces 10 tons of rice per person, so country B has an absolute advantage in producing rice."

The professor bowed slightly at him, "That's right, so which country has the comparative advantage in producing rice?" ”

Fang Wei, who had just sat down, raised his hand desperately, and the professor motioned for him to answer.

Fang Wei was full of confidence and replied again: "Country B." ”

The professor nodded, "Then let's ask this student to come up and draw the boundary line of production possibilities, and analyze why country B has a comparative advantage in producing rice." ”

The smile on Fang Wei's face suddenly froze, he flipped through the book in his hand, and tried to find the drawing method of the boundary line of production possibility from the book, but unfortunately he couldn't find it, so he had to take the textbook to the podium.

When he arrived in front of the professor, he naturally didn't have the face to turn the book, so he could only put on a thinking face.

Time passed bit by bit, Fang Wei never put pen to paper, and the classmates below had already begun to whisper.

Fang Wei's face gradually turned red, he picked up the chalk and only scribbled a coordinate, plus half a bracket, and went back to his seat without waiting for the professor's evaluation.

This is clearly not the correct way to draw the boundaries of production possibilities.

The professor frowned and asked, "Do the others have different opinions?" ”

The students below were collectively silenced.

The professor had to pick up the roll call, "Zhang Hu." ”

A big man huddled in the corner of the last row of the classroom and napping stood up in a daze as others pushed him.

His attitude was particularly sincere, "I'm sorry, Professor! I didn't hear clearly, can you say it again? ”

There was a burst of laughter.

The professor shook his head, his face sank, and he said, "If none of you in your class can draw the boundaries of production possibilities, then everyone will lose five points from their final exam scores." ”

The crowd who were originally smiling suddenly became as quiet as chickens.

Mu Wenxi pushed Lin Yao and motioned her to go up and draw the boundary line of production possibility.

Lin Yao didn't have the heart to come up with that, and she didn't think that the professor would really deduct five points from everyone's grades, it was just to help everyone tighten the strings in this way and be able to listen carefully.

Lin Yao is naturally not worried that she will fail the final exam, even if her score is deducted 5 points, passing is not a problem, but others may not.

Zhang Hu and the others looked at Lin Yao with blank eyes, even Fang Wei glanced at her from time to time, and Mu Wenxi directly grabbed her sleeve and pulled it on the ground.

Lin Yao was puzzled, and asked her with her eyes: You won't?

Mu Wenxi bit her lower lip and nodded slightly.

Lin Yao knew that Mu Wenxi's work had nothing to do with international trade, and she didn't listen to it at all.

The University of Technology still takes a lot of thought when formulating the postgraduate training plan, which not only requires them to master a certain depth of professional knowledge, but also requires them to reach a certain breadth of knowledge.

This means that they need to take dozens of courses in total to earn enough credits.

However, most of them are social people with work experience, and they only want to take some of the courses that are useful for their work or that they are interested in.

They take other courses, and they really just come to mix up credits.

Taking the course of international trade as an example, a few in the front row may be able to listen to a few sentences, in the middle row, there are many people playing with mobile phones under the desk, and even chasing dramas, and those in the last rows are either dozing off like Zhang Hu or playing old K, so they can't even answer such a simple question.

If you stand in the professor's point of view, he is working the stage, and the first question he asks is also the simplest and most basic question, and the student either perfunctory or simply admits that he did not listen...... It's impossible to say not to be disappointed.

Everyone understands his feelings, but the professor is so disappointed that he wants to deduct five points from the final exam of all students, which is unacceptable.

Perhaps everyone looked at Lin Yao with too eager eyes and too obvious, and the professor noticed this student who was sitting in the middle of the front row and looked extremely young.

The rest of the game fell into place.

Under everyone's gaze, Lin Yao calmly walked to the podium, she picked up the chalk, easily drew the production possibility curve, and then analyzed: "From the production possibility curves of the two countries, it can be seen that the opportunity cost of producing rice in country A is 0.2, while that of country B is 0.125, so the opportunity cost or relative cost of producing rice in country B is lower than that of country A, and country B has a comparative advantage in producing rice." ”

The students almost applauded, but the professor did not let go, and everyone looked at the professor with blank eyes.

The professor's face turned slightly pale, and he cleared his throat, "It seems that at least one of my classmates has listened to the class, so I won't deduct five points from everyone's final exam scores." ”

Everyone breathed a sigh of relief.

"However......" the professor added: "Today's question is only the most basic and simple, if you can't even answer such a question, then, in the final exam, whether I deduct points or not, everyone here will probably not pass."

There are probably not too many people who can successfully graduate after three years. ”

Studying for three years in graduate school but not finishing it?

I have to say that this possibility is still there, and it is quite embarrassing, and it is not easy to deal with it on the side of the unit.

Everyone's faces fell again, except for Lin Yao.

After this episode, everyone seemed to be wound up, the atmosphere in the classroom was much better, and the professor's face finally became gloomy as before.

That's all for later.

After school at noon, Lin Yao and Mu Wenxi were talking and laughing, and when they walked to the cafeteria together, Lin Yao's mobile phone rang, it was Chen Manman.

Lin Yao's study at the University of Technology, several people in the company know about it, and they will only call when they have something important.

A few days after the establishment of Excellence Industry, the import and export related procedures have not been completed, and the old customers' orders are still placed in the original agency to ship, and the new customers do not know that the Year of the Monkey can only be made.

What could it matter?

Lin Yao picked up the phone puzzled.

Chen Manman said anxiously: "Miss Lin, Xiao Zhang and Xiao Li didn't come to work today, I just called them to find out that they entered the police station, what can I do?" ”

Lin Yao's footsteps paused, "Police station? ”
