Chapter 107 Midterm Exam
Zhao Zhaodi was a little hesitant.
Zhou Miao also hurriedly said: "Yes, Zhaodi, don't catch a cold just to save money. Besides, a cotton coat can be worn for several years. If you don't buy it this year, you will have to buy it next year. You can't wear these clothes forever, right?"
Li Huanhuan also nodded: "I still have some money in my hand. I will lend it to you. You can return it to me when you have money in the future."
Zhao Zhaodi heard this, and her defense line in her heart fell a little, but she was still a little hesitant: "I can still make it this month, and I will have money next month."
Her family conditions are not good. Her husband came to the city to work and take care of the children. Although he doesn't need to support her studies, the pressure of life is still great.
Sijiucheng is not like her hometown, everything is much more expensive, so they don't have any money saved.
Dabao has already reached the age to go to kindergarten, and she and her husband only saved up the money for kindergarten last month.
Shen Sangyu probably knew what Zhao Zhaodi was thinking, and whispered: "What are you going to do next month? Go now, take the child with you, and go to the supply and marketing cooperative to look at clothes."
Zhao Zhaodi was stunned.
Shen Sangyu said: "Don't let the child get cold."
This sentence made Zhao Zhaodi's eyes red.
This time she didn't refuse again. After saying a rough date for repayment, she went outside with everyone to pick up Dabao.
Shen Sangyu met Zhao Zhaodi's husband. He was a very honest man. He was not tall for the north, and lived in a shed with his son.
The shed was very simple, it was built with blue and red curtains and some wood. It was not a big place, but it was full of people, and the environment was not very good.
But the young man adapted very well.
He saw Zhao Zhaodi coming and ran over quickly.
The shed was full of men, Shen Sangyu and the others did not go in.
It was obvious that this was not the first time Zhao Zhaodi came here. On the way here, she brought a box lunch from school to her husband.
The man smiled honestly. Hearing that he was buying clothes for his son, the man quickly took out the wrinkled money from his pocket: "Don't just buy clothes for Dabao, buy two sets for yourself too. Beijing is not like our hometown, so don't catch a cold." The man
spoke in dialect, and Shen Sangyu, who was outside the shed, could not hear clearly.
Shen Sangyu, however, absolutely believed that Zhao Zhaodi's husband was a good man.
Even though the family was living a difficult life, he still chose to leave his hometown and brought his wife and son to work in the unfamiliar city of Sijiu after hearing that Zhao Zhaodi had the opportunity to study.
After a while, Zhao Zhaodi burst into tears with red eyes.
Shen Sangyu took advantage of the fact that the supply and marketing cooperative was still open and took Zhao Zhaodi to buy clothes.
Compared to buying ready-made clothes, it is actually cheaper to ask a tailor to make them, but the weather is cold now, and it takes at least half a month to make a piece of clothing, which is not enough time.
So in the end, Shen Sangyu bought a set of clothes for each of them.
When Dabao came, he only wore a thin sweater and coat, and when he left, he had two sets of new clothes and cotton pants.
Mom said she would give money to her sister, but her sister said that it was to buy her new clothes for the Chinese New Year.
Dabao thought that the Chinese New Year was still a long time away.
But this did not prevent him from being happy.
Because when he left, his mother also bought a black cotton coat and warm pants for his father.
This winter did not seem to be as cold as usual.
In the end, Shen Sangyu only took the money for Zhao Zhaodi's clothes and asked her to pay some back every month.
Zhao Zhaodi knew that Shen Sangyu was helping her sincerely, and she kept saying thank you. She could not do anything to help Shen Sangyu on weekdays. Knowing that Shen Sangyu had to do experiments for the midterm exam and had no time to eat, she simply went to deliver meals every day at noon.
——Originally
there were no midterm exams for freshmen, and other teachers did not assign any assignments. Only Qin Duanshan gave a topic.
It was not difficult for Shen Sangyu, but it was a headache for students who had just officially come into contact with physics.
Qin Duanshan gave four topics during class that day. Each pair of people worked on a topic. According to the lottery method, Shen Sangyu drew the topic of underwater propulsion research. Shen Sangyu
naturally asked He Huai to go with him.
Shen Sangyu could probably guess some of the topics given by Qin Duanshan. In the next few decades, China will basically revolve around these topics.
Among them, underwater topics are the slowest and least studied.
It is not only China, but also other countries.
There is too little underwater exploration in any field. Before she traveled through time, human exploration of the ocean was less than 5%, but the ocean covers 71% of the earth's surface, which means that for humans, 95% of the ocean floor is still unknown.
Resources will run out one day, so after exploring on land, people will naturally turn their attention to the sea.
However, there are still many unresolved problems.
How can humans go to the sea?
Ancient humans built ships, and now people build submarines, but even so, the degree of exploration of the ocean is only 5%.
Shen Sangyu calculated the time, and Qin Duanshan was indeed going to start thinking about submarines at this time, so this topic is probably also for the purpose of selecting useful talents?
Shen Sangyu narrowed his eyes, glanced at He Huai who was still unaware of the situation, and suddenly asked: "Are you confident?"
He Huai said without hesitation: "Of course I am!"
Shen Sangyu smiled: "If you are confident, then let's do it!"
Then He Huai saw that Shen Sangyu seemed to be full of energy, and took him to the library, and accurately found several thick books.
He Huai swallowed his saliva, and had a bad guess in his heart: "What are you going to do with so many books?"
Shen Sangyu directly handed all seven or eight books to He Huai, and said seriously: "What else can we do? Teacher Qin gave us three weeks to experiment, so within a week, you should read all these books roughly. I will tell you the key points, and then we will make the model."
Shen Sangyu said, and then quickly began to think about the production cost.
Generally speaking, schools provide subsidies for students to do experiments. Otherwise, experiments are so expensive. How can a student with nothing have so much money to do experiments?
He Huai, who was standing aside, was still immersed in shock.
Seeing the book in his hand, his body couldn't help but tremble.
"So... can I drop out of school and take the college entrance examination again next year?"
Shen Sangyu looked at him with a murderous look, and He Huai shut up instantly.
He Huai was helpless: "Then... then I will try my best."
There were exactly seven books, and it was not impossible to read one book a day.
That day, Shen Sangyu called back to the military area to tell Wen Qingchuan that he had to do an experiment and could not go home.
Wen Qingchuan was slightly disappointed and asked, "Then you should take care of your health, don't save money at school, and order some stir-fried dishes every day."
After a pause, Wen Qingchuan said, "Don't eat dry mixed rice noodles every day, it's easy to get malnutrition."
Shen Sangyu: "..."
After thinking silently for a while, it seems that I had dry mixed rice noodles for lunch today.
Shen Sangyu's face was a little hot, and she hurriedly said, "I'll go eat stir-fried dishes tonight!"
Wen Qingchuan laughed on the other end: "Then you had dry mixed rice noodles for lunch again?"
Shen Sangyu: !!!
The little girl snorted coldly and hung up the phone.
On the other end, in the military compound.
The sound of Shen Sangyu hanging up the phone was loud, and Shen Xu, who was eavesdropping on the side, heard it clearly.
Seeing his boss standing there in a daze, he couldn't help but laugh: "Boss, have you made your sister-in-law angry again?"
Wen Qingchuan glanced over: "What do you mean by again? When has Sangyu ever been angry with me?"
Shen Xu immediately felt a handful of dog food stuffed into his mouth unexpectedly.
"You are the only one who has a wife, right?" Shen Xu muttered, and then asked in a sly way: "Sister-
in-law won't be back this weekend?" As he said that, Shen Xu glanced at the bag of rice noodles in Wen Qingchuan's hand.
"Yeah." Wen Qingchuan had no emotion on his face, and glanced at Shen Xu: "Call the brothers tonight, I'll treat you to dry mixed rice noodles."
Shen Xu: "...No, we have been eating dry mixed rice noodles for a week!"
-
Shen Sangyu hung up the phone and returned to the dormitory to start calculating the cost of making her simple model.
The underwater power model she was going to make was the most basic key to a submarine.
Now Shen Sangyu didn't know how far China's submarine technology had developed, but before she crossed over, China's submarines had already passed a depth of 3,500 meters, and she was studying a depth of 10,000 meters underwater at the time, but she crossed over when she was halfway through the experimental research.
China's current technical conditions are not yet capable of exploring a depth of 10,000 meters, but 3,500 meters is still possible.
Shen Sangyu lay on the table and wrote down the equations and the money needed for the materials, planning to ask Qin Duanshan for reimbursement tomorrow.
Shen Sangyu stayed up until two in the morning, and finally went to bed because she couldn't hold it anymore.
As a result, Shen Sangyu successfully stayed in bed the next day.
There are only four of them in the dormitory now. Today is the weekend and there are no classes. Zhao Zhaodi goes to accompany Dabao every weekend, while Zhou Miao and Li Huanhuan go to the library to study.
Knowing that Shen Sangyu has an experiment to do, Zhou Miao woke her up in the morning when she saw that Shen Sangyu had not woken up yet.
Shen Sangyu is not grumpy when she gets up, but that doesn't mean she doesn't stay in bed.
Shen Sangyu was still a little confused when Zhou Miao was talking to her. She stretched out a finger and said, "Sleep for another ten minutes, just ten minutes..."
After saying that, she put the quilt on her head and fell asleep in less than a second.
Seeing this, Zhou Miao couldn't help but complain to Li Miaomiao, "Is Sangyu hibernating?"
She didn't fall asleep in the summer, did she?
Li Miaomiao nodded seriously, "I think so."
After that, the two of them could only resign themselves to calling Shen Sangyu to get up.
Finally, Shen Sangyu was no longer sleepy, and got up from the bed in a daze.
It took a long time for his brain to react. Shen Sangyu seemed to have thought of something and jumped out of the bed: "Fuck!"
Zhou Miao watched Shen Sangyu get ready in less than five minutes, and then hurried downstairs without even saying hello.
Zhou Miao felt a gust of wind running past her.
