"Yaaaa I'm so angry, the bracelet is broken! ”

Chen Bo was so angry that he jumped up and down, and almost hit his head against the wall.

Wang Xu looked at it seriously and said: "Don't say it, the degree of reproduction of the movements and demeanor is quite high, and people have not made the wrong title." ”

"The 30,000 yuan in hand is gone, and today it is a white movement." Chen Bo tossed until he couldn't breathe, and finally stopped.

Wang Xu put the keyboard on his back and said patiently: "Change your mind, if you don't have that 30,000 yuan, there will be no way to talk about troubles." ”

"No, I'm going to buy a new bracelet, I don't make this money, it's uncomfortable."

Chen Bo was not discouraged, what does it matter if you let it go for a day, weight loss is expensive, you have a large base, fast calorie consumption, and your innate advantages are incomparable to ordinary people.

"Okay, there is a maple leaf experience store near the outside of the school, and I will go there after class."

"yes, I understand."

Saying so on his lips, he was worried about the bracelet in his heart, walking on the school road, Chen Bo was full of bonuses, and he couldn't raise any interest in learning.

The location of the class is in the library, and this class teaches "Book Information Retrieval", Chen Bo did not understand the teaching content in advance, threw away his bag, and propped his hands on the table to enter a deep daze mode.

"Hey, let's connect the keyboard and pretend to be it, okay?"

"Oh."

Chen Bo replied weakly, pulled out the tangled keyboard with an irritated expression, and slammed it directly at the jack.

"Why can't I get it?"

"I'll see." Wang Xu leaned in and glanced at it a few times, sat back and said, "The jack is broken, you can change your seat." ”

"There is always a sense of foreboding when I commit a water reversal this time."

Chen Bo picked up his backpack and shifted to the seat on the right.

"Don't take money too seriously, sometimes you have to have it in life."

"Maybe I've been poor for a long time, I wasn't like this before." Chen Bo scratched his head and calmed down a little.

Wang Xu reminded earnestly: "Exercise should be moderate, too much, remember to replenish water and nutrition in time, otherwise the gains outweigh the losses." ”

"Don't worry, they're all adults, and there's still some common sense." Chen Bo breathed a long sigh of relief and didn't think about bad things for the time being.

There is a special electronic reading room on the top floor of the library, which is usually used for study and seminars, and will be temporarily redeployed during classes.

Most of the floors are self-study rooms, slightly different from the bottom, the self-study rooms on the top floor need to be booked in advance, the environment is relatively closed, the compartments are relatively small, can only accommodate 4~8 people, there are two spliced rectangular tables in the room, with a full set of electronic equipment, it is a treasure place for club meeting planning.

The teacher who taught the class was one of the librarians, a middle-aged man with a beer belly, a large set of keys hanging from his waist, and he walked with a long noise.

This course is an elective course, the popularity is not high, but the practicality is very strong, keyboard application is different from other majors, the elective basically does not have to choose by yourself, it is a temporary notice, shouting what to go to, and protesting does not work.

"Hello everyone, I am very happy to teach this course to all of you, and I hope you will take care of it."

The administrator himself has no title, but he is just stained with the budding shade of his father, and he has an idle job in school, and he usually tries to be familiar with the business, and tries his best not to make mistakes and not offend people, that's all.

There was a short but enthusiastic round of applause, and despite the fact that there is a separate partition on the top floor, the library is a quiet place to study, so as not to disturb others.

"The knowledge we learn today is the library classification method, which is a representative large-scale comprehensive classification compiled and published after the completion of our country, and is the most widely used classification system in domestic libraries today, referred to as the "Zhongtu Law".

"The taxonomy was compiled in 1971 and is now in its seventh edition."

Faced with the students of keyboard application, the administrator was so nervous that he stuttered a little.

"You were born in a period of strong rise in e-books, and you may not have as much impression of paper books as our generation, but it doesn't matter, the library still retains a large number of paper books for students to browse."

"Taking this course can make it easier for everyone to find the books they like, let's do a simple questionnaire, and I will take a look at the raised hand of those who have never been to the library until now."

"This teacher asked clever questions, knowing that some people were too shy to raise their hands, so they deliberately asked the other way."

Chen Bo sat behind him, the situation was clear at a glance, and no one raised his hand.

Wang Xu interjected: "We must have been to the library in our major, and if there is a class in the first semester of our freshman year, don't we just ask us to copy famous quotes and take pictures." ”

"yes, forget about that." Chen Bo pretended to be confused.

"Of course you forgot, you went to celebrate Children's Day for Kiki that day." Wang Xu made up for it coldly.

Chen Bo didn't reply and continued to listen to the teacher.

"When you are searching for books, are you surprised why the books are so strangely numbered? It's both letters and numbers, and it's very inconvenient to find the corresponding bookshelf. ”

"This is because our taxonomy uses a mixture of Chinese pinyin letters and Arabic numerals, with the first letters indicating a large category and the lower subdivisions represented by numbers."

"It should be noted that the Chinese pinyin alphabet here is not the first letter of the subject, it only indicates the order, for example, philosophy, the corresponding is not Z, but B, a letter can refer to multiple disciplines, or take B as an example, it includes philosophy, religion two categories."

"The school library has limited space, and it is difficult for the collection to meet the needs of students in all aspects, so most of the books provided are closely related to the major, and the serial numbers are mostly concentrated in A to O.

"I ask you, what does K correspond to."

"History and Geography." Chen Bo blurted out.

"Great, not bad."

Chen Bo said frankly: "I happened to be looking at the table of contents, why are some of them double letters?" I don't think I've seen it. ”

Wang Xu explained: "The two-letter letter corresponds to industrial technology, which is practical, and the school basically does not have it. ”

"The school's collection is so small, less than half of that of Qingbei."

"In the era of e-reading, there is no problem of physical books, and the reading room has a special account and all kinds of commonly used literature materials."

Wang Xu didn't come many times, but he was familiar with the operation of the library system, but it was a pity that the account only bought academic literature and journals, like any entertainment magazine, and still had to pay extra money to buy it.

"Huh? There are also discounts. Chen Bo noticed the membership benefits in the upper right corner.

Wang Xu glanced at it a few times, and landed on his own account, the membership level was higher, and the frame would flash, which was a black gold glare exclusive to the big guy.

"It's like this when you spend more, the discount on my account is greater, and I sweep the goods at half price."

"I didn't expect you to be a person who loves to read."

It can be more advanced than the library's special account, and the bookshelf is a huge number of books.

"In the past, my family was forced to write reading notes, so I opened a monthly subscription to read, and it became like this." Wang Xu's tone revealed helplessness.

"I'll take a look, the monthly reading ..... is 1980 yuan/month."
