Although the next two sections are about computers, the first two sections are more difficult and difficult in advanced mathematics.
Higher mathematics classes are held in small classes, with two classes taking classes together. The classroom is also small and can barely accommodate two classes. In this way, if there are a few tall people in the front, those sitting in the back rows will basically not be able to see under the blackboard.
Half part.
Worried about not being able to get a seat, Zhou Yan arrived at the classroom half an hour early, but the first few rows were already occupied. Zhou Yan could only make do with it and took out various teaching materials from his schoolbag.
I occupied a row directly.
At about 7:50, a group of animals in the dormitory, who had slept until they woke up naturally, rushed into the classroom panting heavily...
"This way!"
In the first class, the senior mathematics teacher simply introduced himself and started teaching. The senior mathematics teacher also knew that it would be difficult to follow the lecture later, so he even received a loudspeaker.
The first part of advanced mathematics, sequence and limit, is not difficult, but because it is basic, the teacher explains it very carefully and slowly.
Before you know it, two hours have passed.
When many people are still not satisfied, the advanced mathematics class is over.
"Students, it is not easy to learn advanced mathematics. It requires a lot of hard work, and it is useless to assign homework after class. Therefore, it all depends on everyone's self-consciousness..."
"get out of class is over!"
The students from Class 4, who were originally serious, immediately showed bright smiles after leaving the classroom: The next two classes are computer classes!
However, when a group of expectant teenagers rushed to the designated classroom, they found that it was not a computer room, but an ordinary classroom.
A deep sense of loss arose spontaneously.
The content of the computer class is similar to what Zhou Yan learned in high school. The beginning is all about von Neumann and Eniac. The next step is to introduce the smell system, and then binary to decimal conversion.
"Divide by two to get the remainder" and "expand according to powers" made a group of older adults dizzy...
"I need to eat braised pork at noon to refresh my brain!"
In the cafeteria of Jinshan Campus, the meals that impressed Zhou Yan the most were the huge rice bowls and braised pork stewed with kelp, frozen tofu: the dishes on the rice bowl were basically as good as a plate; while the braised pork was fat.
Not greasy, fresh and attractive.
It's a pity that after becoming a chef, Zhou Yan has no luck: nothing he eats tastes good.
The two classes in the afternoon are mechanical drawing, which in other schools is called engineering drawing.
The starting content of all college courses is in line with high school, and is not very advanced. Mechanical drawing is no exception. The first frame and projection are just a repetition and improvement of high school geometry.
However, low difficulty is one thing, but poor spatial imagination is another matter...
For Zhou Yan, who has never left the mechanical industry and has the bonus of a "worker bee" mechanical doctor, mechanical drawing is naturally the most basic thing.
However, during class, Zhou Yan still listened very seriously: After using computers for nearly twenty years, freehand drawing is a bit rusty...
After class, Zhou Yan's roommates put their swords and guns in storage and put their horses on Nanshan, either playing ball or playing soccer.
Zhou Yan stayed in the teaching building again.
Zhou Yan had already registered online the day before the CET-4 registration, and the rest still had to be entered.
In an era when smart phones are common, individuals can collect images with just a mobile phone, but now it is 2006...
"Tilt your head!"
"Look up!"
After being directed by school staff for more than a minute, Zhou Yan was freed.
Then, go back to the dormitory and wash clothes.
Although the dormitory building on the Jinshan campus is newly built, the supporting facilities are not complete: the bathing center is across the road outside the campus, and as for the washing machine, there is no need to think about it at all.
Poor Zhou Yan, a single dog who has been using a washing machine for more than ten years, still has to wash clothes by himself.
There is no washing machine, let alone a dryer, and the dormitory building does not have a balcony. The washed clothes can only be hung in the dormitory. In order to prevent dripping, they have to be wrung out and a basin is placed below to catch the water. p>
Looking at the dripping clothes hanging on the bedside, Zhou Yan suddenly missed his dryer...
How about making one yourself?
After the idea came up, Zhou Yan couldn't hold down the button anymore and didn't want to.
Although there are heaters in the city in Yunzhong in winter, which can dry clothes, the situation in the student dormitory is a bit special. One radiator and five or six people washing clothes are not enough at all.
Especially Zhou Yan, who gets up early every day to exercise and needs to wash his clothes frequently.
So, during evening self-study, Zhou Yan had something to do.
The dryer is actually a combination of a hot air machine and a fabric wardrobe. Even if it has a timing function, it is implemented by a mechanical device. It is not considered an electronic device at all, but can only be considered an electrical device.
Originally, Zhou Yan could just "copy the work" and accept the request completely, but unfortunately he thought the heater fan was too noisy, so he had to separate the electric heater and the fan. In this way, the silent low-voltage fan would need to be equipped with a rectifier and voltage reduction circuit.<
/p>
Zhou Yan worked hard for two nights of self-study and finally managed to do something good: one night was spent designing circuits, and the other night was spent doing structural and appearance design.
The experience is all ready-made. The mechanical and electronic design experience comes from the "worker bees", while the appearance design comes from Han Shangyan. Although he changed his career to network security, his industrial design level is still somewhat impressive...<
/p>
However, the design work of the entire dryer has been completed and it is already the weekend.
get out of class ended at noon on Friday. After lunch, Zhou Yan first called home to report that he was safe. He listened to his parents nagging for more than half an hour before hanging up the phone and resolutely boarded the bus into the city. The destination was naturally Railway station.
After arriving at the place, Zhou Yan stood under the stop sign and started waiting for the legendary No. 7 bus that "ghosts see sorrow".
While Zhou Yan was waiting for the bus, a group of arrogant young people were also waiting for the bus.
"No one sells tickets for bus No. 7, the train station..."
A group of migrant workers with bulging pockets heard the bus announcing the stop and rushed over in a hurry.
The young people next to Zhou Yan had a strange light flashing in their eyes: There is a big fish!
Seeing this group of young people surrounding them, Zhou Yan also followed them!
When the bus driver saw a group of "acquaintances" gathered around him, he stood up and shouted: "Don't be anxious, don't be crowded, there are still a lot of empty seats on the bus!"
A young man in the lead glared at the bus driver and continued to push up.
"Oh, my holy mother's heart!"
Zhou Yan squeezed over from the side, stretched out his hand very secretly, and lightly "rubbed" the migrant worker's arm. The man's hand suddenly rose uncontrollably, hitting someone behind him who was reaching out.
The face of the gentleman on Liang Shang.
"Pa..."
"Ah, I'm sorry..."
According to Zhou Yan's memory, thieves during the Republic of China generally did not try again after their attempt failed.
But what makes Zhou Yan find it incredible is that this thief who failed to succeed was either because of his perseverance or because he was angered by the migrant workers' elbow. After getting in the car, this gentleman from Liang Shang started to fight with the migrant workers. Seeing that the thief was about to commit another crime, Zhou Yan approached him again "inopportunely".
This time, Zhou Yan did not hunt the cow across the mountain. Instead, he waited until the thief stuffed his wallet into his pocket, then quietly took out the knife from his pocket and went over. Taking advantage of the bus turning, he moved forward and cut it open.
The thief took his wallet out of his pants pocket.
After the bus turned around, Zhou Yan returned to the migrant workers and stuffed his wallet back.
I thought I had succeeded with three hands, but without even confirming the result, I got off the train at the next stop...
