A new week has begun, and although the volunteer activities at the end of the weekend were not satisfactory, they still played a lot of positive roles for the students of Class 7 of the Department of Computer Science. At least Lin Yu had already found that there were a lot more students sitting in the front row of the classroom, and few people were sleeping on their stomachs in class.

Maybe it's because they feel that if they don't work hard, it's too wasteful, in the eyes of the children in the orphanage, every moment now is probably the life they dream of.

The professor on the podium was in high spirits today, because he found that the students sitting in the classroom were behaving so differently than before, and he was teaching an obscure basic subject, "Circuits and Analog Electronic Technologies". Theoretically, this course is of course important for computer science students, and if it is done well, it will give you a deeper understanding of the principles of the entire computer operation. In practice, however, it is of little use, because no one thinks about how the electronics in a calculator work when programming.

The professor doesn't have to think about it to know that all the computer students here must want to develop in the direction of software, after all, the momentum of several major Internet companies is too strong, and the salary is also at the top level in all industries, so everyone wants to become the software development or network maintenance personnel of these companies, in contrast, "data structure", "database system", "software engineering", these courses are more important.

In addition, "Circuits and Analog Electronic Technology" itself is claimed to be one of the most difficult courses in the computer science department, so many students have already given up in the first class, and they only need to try their best to pass the 60 points at the end of the semester to get through this difficult time happily.

Therefore, when class, the professor can see that there are basically few students in the front row seats, everyone is sitting back as much as possible, and only a few female students who are top students will still sit in the first three rows and take notes seriously. Other students either fell asleep on their desks or lowered their heads and put their phones under their seats to play games, a situation that professors have long been accustomed to.

Over the years, the professor has taught basically every class of students, and once he tried to maintain order in the classroom, slapping the podium a few times with a blackboard, and telling his classmates that they were not allowed to sleep or play games in his class.

But it may not last more than twenty minutes for the situation to improve, and the students will soon be the same again. Over time, the professor didn't bother to bother, and only regarded the class as a task that would end in forty-five minutes.

But on this day, the professor saw the situation can only be described as surprise, not only did he find that the first three rows were all filled with students, but also that no one in the class was sleeping on his stomach. When I explained a principle clearly, I even got a response from the students under the podium who nodded slightly.

The professor's enthusiasm for teaching was aroused at once, although he didn't understand what made the students change, he felt that his teaching work was finally recognized today, and the students were all listening to his lectures seriously!

An unconcealable smile appeared on the professor's face, and he began to spit on the podium, and even his voice became more sonorous...

At nine o'clock in the evening, the students of Class 7 finally finished their day's classes, and they dragged their tired bodies back to the dormitory.

Without sleep breaks in class and mobile games to distract from them, it is naturally difficult to stay through the pure lectures and lectures. The physical exhaustion has alleviated the guilt in their hearts a lot, and many male students have begun to relax themselves by playing games again, while female students have also clicked on the TV series that they haven't finished chasing last week, and watched it with great interest while eating snacks. By the time the lights went to bed, some of my classmates had already begun to make up their minds, should I skip the first two classes tomorrow? I haven't slept for a long time...

Lin Yu still checked the Heavenly Mailbox on the way back to the dormitory, and he found that Xu Feihang's father was replying faster and faster, and the letter that was just sent out yesterday was immediately replied to today. Lin Yu took out the envelope from the Heavenly Kingdom mailbox and carefully put it into the pocket of his clothes.

Before the door of the dormitory opened, Lin Yu heard the unfamiliar game sound, "All attack!" Lin Yu smiled at the corner of his mouth, he knew that the situation in today's class would not last long, and sure enough, before the night passed, everything would return to the past.

When Lin Yu walked in, he saw that this time his two roommates were playing games, and even Xu Feihang was playing happily in front of the computer. It seems that he didn't expect his father to reply so soon, and when Lin Yu passed by him, he quietly put the envelope on Xu Feihang's table.

Xu Feihang's face was suddenly full of surprise, just a day had passed, and his father actually replied. Xu Feihang couldn't help but shake his hand, and the hero he controlled rushed into the fierce battle circle at once, and was instantly killed by the enemy hero.

A line of words soon appeared on the computer screen, "Who was that just now? Why did you run out and die, wouldn't it be another elementary school student?"

Xu Feihang looked very embarrassed, anyway, his side basically lost this game, because the defense towers of the three roads had been demolished, and the enemy heroes had already begun to attack the crystals of their own camp. Xu Feihang didn't have the face to fight side by side with those people anymore, so he simply quit the game early.

Zhou Guanghua was fighting fiercely, so he didn't notice that Xu Feihang actually received another letter, otherwise he would definitely question how the current letter delivery could become so fast?

In his last letter, Xu Feihang told his father that his relationship with his mother was not the same as before. Although her life has become much richer, her mother has become very busy, she often goes out early and comes back home late, and Xu Feihang can't remember the last time she ate her mother's cooking.

He only knew that during the days when he was still living at home, he often opened his eyes to find that there was only himself and his sister in the house, and there would be a note left by his mother at the bedside, and a hundred yuan bill with the note.

The words left on the note are usually the same, "Mom and Dad have gone out beforehand, you can buy food with your own money, and take good care of your sister." ”

Xu Feihang often looked at the notes and hundred-yuan bills in a daze, and he had a feeling that these things seemed to have become the only connection between himself and his mother.

Xu Feihang still remembers that when he used to live in that valley, he could always hear his mother's gentle voice waking him up, and the dinner table would be prepared for a not rich, but steaming breakfast.
