Chapter 115: Let's learn punctuation first (ask for subscription)

Jin Yu stood on it and looked at the students of different ages below, some had a headache, some were only seven or eight years old, and some were already seventeen or eighteen. Pen ~ fun ~ Pavilion www.biquge.info don't care, let's introduce myself first, Jin Yu cleared his throat and said: "My name is Jin Yu, and I am responsible for teaching you new arithmetic." You can call me Teacher Jin, and Dr. Jin will also become a doctor. The teaching method is up to me, and if you can't accept it, you can quit, as long as your parents agree. ”

"In my class, if you don't want to learn, you can sleep and read, but you can't make a noise, and you're not allowed to talk to each other, of course, and you are not allowed to snore when you sleep."

It was the first time for the students of the Tang Dynasty to hear such an alternative opening statement, and for a while there was suppressed laughter below.

"Even if you learn very poorly, as long as you want to learn, I won't give up on you, but if you give up yourself, then I can't do anything. My teaching is different from other PhDs, you can always ask if you don't understand something, as long as you raise your hand first, just like this. Jin Woo made a gesture of raising his hand to illustrate.

"Next, please introduce yourself after you go." Jin Yu pointed to a young man on the left and said.

"Student Qin Huaiyu." Xiao Qin sat in the front row, stood up and saluted Jin Yu and the other classmates, and then did it.

"Yes, that's it." Jin Yu praised Qin Huaiyu and motioned for the next classmate to continue.

There were less than thirty people in the class, and it didn't take long to introduce them one by one, several of them were Jin Yu's old acquaintances, Li Chengqian, Li Ke, Li Tai, Cheng Huaimo, Qin Huaiyu, Changsun Chong, Meng Zimo, among them, there was a white-faced baby who claimed to be called Li Zhi Jin Yu was slightly surprised, he didn't know that Li Zhi was still a nursing baby, and when the wedding was introduced, he only said that the baby was the Nine Emperors, but Jin Yu had not studied Li Er's genealogy, and it was definitely not clear. So he took it for granted that this was the future emperor, of course, provided that Li Chengqian was still so uncompetitive.

"Arithmetic is ubiquitous in life, from how much you spend a day, how to save money when you buy things, how much the imperial court taxes in a year, how much each yamen budget, and how to make the country and the people rich and strong more effectively." Seeing that some of the students didn't quite understand, Jin Yu made another popular analogy, "Everyone knows how to ride and shoot, right?" How far a bow and arrow can shoot is probably only a rough estimate, right? But if you learn arithmetic well, you can calculate very accurately, how can the trebuchet hit the target more accurately? You can also calculate it. If you want to have these skills, you must lay a solid foundation and not accumulate steps, which is the truth. Okay, let's start with the first lesson of arithmetic -- getting to know the number ''''''."

When Jin Yu came, he brought a few pieces of chalk with him, and he just used them. Write out the Arabic numerals 0-9 one by one on the blackboard, and then mark the Chinese characters below in case others don't know them, so it's easy to understand, isn't it?

"These strange symbols will accompany us throughout the teaching process in the future, so let's get to know them and write them five times." Jin Yu pointed to Arabic numerals and assigned an assignment, then wrote the addition and subtraction symbols on the blackboard according to the textbook, and copied a few practice questions. Jin Yu thought very simply, these students have an extraordinary family background, and they have done a good job in enlightenment education, but they are not familiar with the algorithms of mathematics in later generations, so there is no need to carry out enlightenment education like primary school students.

Changle looked at Jin Yu who was preparing the content of the class in the board book in a daze, and her heart was very complicated, when she introduced herself just now, she was under the pseudonym "Li Qian". She obviously saw that Jin Yu was stunned, and thought that she had been recognized, and blushed, who knew that the two of them were thinking wrong, it was a big misunderstanding.

Jin Yu finished the practice questions, learned from the teachers of later generations, went down for a walk, and by the way saw how the students wrote, and the result was miserable. The brush is not very suitable for writing Arabic numerals, some students write the words big, at a glance they don't know that the paper is expensive, some students are making up the pen, the numbers written out look awkward, and what makes Jin Yu feel even more awkward is that the students are not afraid of writing the numbers vertically and are not afraid of the head being crooked.

That's not going to work, gotta tell me about it. Jin Yu walked up to the podium, knocked on the podium with a blackboard, and said: "Everyone, stop, there may be some students who didn't see how to write these numbers clearly just now, I'll mark them for you again, everyone remembers them, and they will write like this in the future." ”

After Jin Yu finished speaking, he used chalk to mark the direction of writing and the arrow next to the number, which was clear at a glance. I haven't seen a teacher tell you how to change this word and how to write it, everything is very fresh. ,

After Jin Yu finished marking, he clapped his hands, looked at what he wrote, there was nothing wrong, and said to the students below: "There is another point that needs to be explained to you, that is, to learn the course of new arithmetic, you need to change your writing habits, and I am afraid that writing from top to bottom is not very applicable." You need to write from left to right, just like I wrote. Jin Yu picked up his textbook and showed it to everyone, although the words were not clear, but the direction of the font could still be seen clearly.

"Sister~~ Dr. Jin, this writing rule has been around for more than a thousand years, I'm afraid it's not okay for you to change it without permission?" Qin Huaiyu thought a lot, afraid that Jin Yu would be attacked, so he raised his hand and stood up to remind Jin Yudao.

"Nothing is static, everything should follow the trend of history, hasn't the new style of arithmetic not appeared before?" Jin Yu motioned for Qin Huaiyu to sit down, and explained with a smile: "Let's just talk about this top-down writing habit." In ancient times, there was no paper, and everyone basically wrote on bamboo slips, so why did they write from top to bottom at that time? I thought it was for the convenience of looking, not for the convenience of reading. ”

Jin Yu reached out and took a piece of paper from Qin Huaiyu's desktop, rolled it up, and said, "Look, for example, this is a bamboo slip, is it convenient to pull it left and right?" Or up and down? Don't forget, the ancient bamboo slips are not so short, they are all rolled one by one, and the text is a little more than a zhang long. ”

"It's easier to leave left and right." Li Chengqian had the highest status among the students, and he had no ill feelings towards Jin Yu, so he cooperated and said.

Jin Yu nodded at Li Chengqian, thanked him for his cooperation, and said: "As for people, they are all partially inert, since it is so convenient, they are used to it." As for people, there are still some blind obedience, so later generations learned it without thinking, and they didn't think about changing it. ”

"Take these symbols and belong to Dr. Jin himself?" Li Chengqian was a little unaccustomed to Jin Yu's new title, and he almost called it wrong. Pointing to the punctuation marks on the blackboard and the Jinyu board book, he asked.

"It's called 'punctuation', and it's used to break sentences, but I didn't create it, I just thought it was easy to use and used it." Jin Yu almost patted himself on the head, why did he forget this stubble? There is no punctuation now, and it will inevitably be used in the teaching process in the future, so one piece explained: "Speaking of this punctuation, this is a long word." ”

After coming to the Tang Dynasty, Jin Yu still had a sense of superiority in later generations, and this sense of superiority arose, firstly, because he was familiar with the general trend of history, and secondly, because of these advanced things.

The students below looked forward to it, and the curiosity and curiosity of people of all ages were there, but they were suppressed after they matured.

Seeing that most of the students below looked at him expectantly, Jin Yu began to talk nonsense again: "In the Xia Shang period, I'm afraid there weren't many words, and it was very troublesome to write a family letter at that time, you have to use sharp stones to carve on the turtle shell, or bamboo, and the better ones in the family will use bronze knives, but they are not durable?" Engrave a few words to change, so a letter to the family has a few words, the general meaning can be understood, and no one bothers to use punctuation to break sentences, after all, it takes effort to carve punctuation, isn't it? ”

"You can imagine that the minister gave Shang Tang a message, 'Head, let's clean up and beat Xia Wei', Shang Tang thought that this was a good idea, and raised his hand to engrave 'agree' on the bamboo slips. But that knife is not easy to use, it hasn't been carved yet, and it's dull, so I have to mumble a few words,, right? ”

Where have the students below ever seen a teacher who gives such a lecture? It's like listening to a joke, and I suddenly can't hold back my laughter.

Jin Yu was not annoyed, and after the student finished laughing, he continued: "You can think about it, in such an environment, who has the heart to use punctuation in broken sentences? Isn't this asking for trouble for yourself? ”

"In the Qin Dynasty, people still inherited this habit of their ancestors. The first emperor and his old man worked hard to unify the text, and they didn't pay attention to punctuation at all. At that time, there was still no paper, and bamboo slips were generally used, how difficult was it to make bamboo slips? If you can write two more words, you don't need to make punctuation blank, right? In the context of the time, punctuation was a waste. ”

"It stands to reason that the Han Dynasty had paper, and writing was also convenient, so there should be punctuation, right? But at that time, there was still no, because there were few words, there were not many people who could write, and the traffic across the country was not as convenient as it is today, so that the people knew that it was impossible to complete it in three years and five years, which was a big project. Emperor Wu of the Han Dynasty was a good emperor, and when he thought about it, he decided to follow the old routine, so no one used punctuation. ”

The little girl Changle saw that Jin Yu was talking interestingly, and finally couldn't hold back her laughter. Li Tai looked disgusted, can this emperor of the past be what a little doctor of yours can comment? But he wasn't brainless, and he didn't say it to sweep everyone's interest.

"After that, it's the Three Kingdoms, right? My ancestors can't stand the war and have left a foreign country, who still has the heart to engage in this gadget? It's still important to eat to save your life, so this matter has been delayed again. Up to now, Guotai Min'an, singing and dancing have been leveled, and they also have the conditions for promotion, so I will tell you about it, if you think it is easy to use, you can use it, and if it is not easy to use, you don't need it, and you don't force everyone. Jin Yu made a long speech, and finally confused the origin of this thing.

Jin Yu's nonsense is not completely unbeneficial, at least the classroom atmosphere is much more active. Everything is in harmony. However, when the class was about to end, Jin Yu also found something inconvenient, that is, the homework is not the same as the Chinese class, and it requires a lot of practice to lay the foundation. Most of the printed products in these years are Yin tuo, the conditions are a little better are male model printing, like this math problem and the like others have not seen, let alone printing, it seems necessary to engage in movable type printing, at least this exercise problem does not need to be copied to the blackboard, and then let the students copy it by hand, and then engage in this textbook or something, it would be better.
