The learning atmosphere here is so good that Jiang Jiuling is a little uncomfortable.

As far as the eye can see, there are no students deserting at all, and everyone is seriously reviewing and sprinting towards the college entrance examination.

In the 90s, students who could go to high school needed particularly good grades, and it was not surprising that it was a key class and the learning atmosphere was better.

Never mind~

On the first day of class, let's keep a low profile, Jiang Jiuling picked up the language book again, and silently began to recite "The Story of Shizhong Mountain".

The next lesson is math.

Mathematics textbooks focus on algebra, plane geometry, and functions.

Now that he can read the math book openly, Jiang Jiuling quickly flipped through it and found that the content in the textbook was not difficult for him, and it was probably only equivalent to the level of mathematics in the first year of high school in later generations.

For example, the question that the teacher is teaching now, there are questions in the high school examination paper last year that are easy to lose marks.

If the figure is a three-view of a geometry, what is the volume of the geometry?

The math teacher drew three geometric diagrams on the blackboard: front, side, and top. Then let the students calculate the volume by themselves below, and later he will explain the idea and the answer.

Jiang Jiuling quietly glanced at Xu Wen at the same table, this question was obviously not so easy for her to solve.

She listed the formula on the manuscript paper, but only half of the formula was listed, and the remaining half was still under consideration.

For Jiang Jiuling, who once memorized almost all geometric volume formulas in order to prepare for the high school entrance examination, the geometric diagram on the blackboard is already regarded as a scoring question, or the kind that is sent uniformly regardless of the quality of the score.

It even gives three diagrams, each of which is marked with a clue to solve the problem, this kind of problem Jiang Jiuling will solve when he was in junior high school, and it is still the kind of one picture.

What kind of geometry is hard?

Here in Jiang Jiuling, it is a little more difficult to have irregular three-dimensional geometry, and it is a little more difficult to follow the ruler and gauge of the five-item drawing method.

will understand, Jiang Jiuling did not list the formula, he wants to listen to the method explained by the teacher later.

His move, in the eyes of Xu Wen at the same table, is naturally a move that will not be anything.

The latter didn't say anything, but he tightened his half-listed formula.

......

At noon, when school ended, Teacher He appeared at the door of the classroom on time.

He beckoned to Jiang Jiuling and said that the meal card was completed, and he could eat three meals a day in the school cafeteria in the future.

The food at noon was not bad, and the food in the third year of high school was even worse. The rice is enough, the dishes are two vegetables and one meat, and there is egg soup to drink.

After eating and drinking enough to leave the cafeteria, Jiang Jiuling also saw two uniformed police officers walking out of the teacher's office building. The teacher who saw off the guests was all smiles, and it was obvious that these two police officers were not here for a student who had done something bad.

Since it is a good thing, it must be Zhang Ying's matter, it seems that Zhang Ying's wish to accept the award on stage in front of all the teachers and students of the school is about to be fulfilled.

Zhang Ying went home for dinner at noon, and Jiang Jiuling wanted to go back too, so he came to class with her in the afternoon by the way. As a result, Teacher He seemed to have installed a positioning radar, and accurately distinguished Jiang Jiuling from the students.

"Ready to go home?"

Teacher He Tongxin was still pushing a brand-new black bicycle, and when he handed over the bicycle and the rear lock key to Jiang Jiuling, he asked Jiang Jiuling not to go back at noon.

"Where's your model excavator?"

"At home, of course. Jiang Jiuling caught this bicycle with some tears and laughter, even though it is the latest model launched by Phoenix Bicycle Factory, it is still the old-fashioned big bar design, but the grip has changed from the previous drooping type to the parallel type that has been used by later generations.

Made of pure iron, it is extremely heavy.

"Bring the school tomorrow. Teacher He pointed to a brand-new three-story white building not far away, "Didn't you kid propose to borrow the school's science and technology building in the principal's office to improve your excavator model?"

"Let's go, I'll take you to the Science and Technology Building now. ”

Jiang Jiuling suddenly became interested, rather than picking up the college entrance examination that he had already taken again, Jiang Jiuling was more willing to soak in the laboratory and tinker with those mechanical equipment.

After all, the college entrance examination is just a goal he set for himself, and this goal is a task, not an interest.

His interest was to become a title engineer as soon as possible.

Every high school has a science and technology building, and the first middle school building is much more magnificent than the second middle school in memory.

Mr. He is the head teacher of the key class and the person in charge of this science and technology building. He owns the keys to all the rooms in the building, and of course he knows everything about the equipment in the technology building.

The first floor is nothing special, it is either an office room or a laboratory room for students to teach physics or technical chemistry.

The second floor began to be divided into categories, electronics, chemistry, mechanics, physics, these scientific disciplines have their own exclusive laboratories, but the equipment in these laboratories is the most basic entry-level.

Although the equipment is basic, Jiang Jiuling is already very satisfied.

He also saw a small lathe in the mechanical laboratory, and when Jiang Jiuling asked Mr. He if he could use this lathe, Mr. He said indifferently: "As long as you know how to use it, you can use the equipment on the second floor." ”

"Anyway, this machine is idle here, you just need to clean the lab when you are done. ”

After visiting the second floor, Mr. He explained: "You remember to bring the excavator model tomorrow, and strive to improve its structure with metal materials within this month." ”

"Actually, I don't say it, you should understand. ”

"I've read your past transcripts, and it's a dream that you want to go to an undergraduate university based on your grades. ”

"Don't care about the fact that I'm speaking so directly, I'm talking about it. ”

Without giving Jiang Jiuling a chance to defend himself, Mr. He's words changed, and his tone was a little sour and envious, "But you have this excavator model!"

"You just have to perfect it, and you can use it to gain the approval of the sacred industrial code. ”

"When the time comes, you can go to whichever university you want to go to, and you will go through the motions for the college entrance examination. ”

"Mr. He, do you think that I can be recognized by the code with this excavator model?" Speaking of the code, Jiang Jiuling became serious, "Becoming a title engineer is my dream that I have been working hard for." ”

It's also my dream.

Teacher He said in his heart.

"At least seventy percent sure. Teacher He also said seriously: "This seventy percent certainty is based on the assumption that someone abroad has already applied for something similar." ”

"If not, I think you'll be 90 percent sure. Mr. He has applied for code recognition three times, but ultimately failed, he is determined: "I am very optimistic about this product, as long as there is no similar product application abroad, you will be successful." ”

"Eighteen-year-old title engineer, the entire Wucheng may not be able to produce one in two years. ”

In Jiang Jiuling's view, success should be inevitable.

But until now, Jiang Jiuling still hasn't decided whether to apply for an excavator model.

Regarding the recognition of applying for the Sacred Industrial Code, Jiang Jiuling had already learned some relevant knowledge through books during this time.

Theoretically, the higher the technical content of the product taken for the first time, the higher the reward from the Codex.

But in the same way, when the second promotion is promoted, the corresponding product has a higher technological content.

In Jiang Jiuling's opinion, the excavator model is a little simple, even if it succeeds, the reward may not be very good.

It is necessary to ensure that the product has high technology content and rich rewards, but also to control it, so as not to affect the subsequent promotion.

This is the problem that Jiang Jiuling is currently struggling with.

If Teacher He knew Jiang Jiuling's distress, he would probably be able to smoke from the seven orifices.

If an ordinary person can design a product that has successfully been approved by the code, he will set off firecrackers to set off a banquet for three days, where can he dare to think about the uncertain factors that will affect the promotion in the future?

"I'll take you on a tour of the third floor. Teacher He didn't know what Jiang Jiuling was thinking, he was in a good mood and took out the key to open the isolation iron fence leading to the stairs on the third floor.

"Students are not allowed to go up on the third floor on weekdays, even if the teacher wants to go up, they have to apply first. ”

Jiang Jiuling looked at the sturdy iron fence and understood that the equipment displayed on the third floor must be very valuable.

Passing through the iron fence, there is also an iron gate in front of the passage on the third floor.

The iron door was unlocked, but the corridor outside the iron door was obviously different from the first and second floors.

Teacher He took two pairs of cloth shoe covers from the cabinet next to the iron door, and handed one of them to Jiang Jiuling to put on his shoes.

Seeing Jiang Jiuling's puzzled expression, Teacher He thought of something, and suddenly burst out laughing.

"Haha~ I almost forgot. ”

"The reason why you were expelled from No. 2 Middle School was that you and two classmates broke the Wang Mang-level vernier caliper in No. 2 Middle School. ”

"Do you know what we have?"

"Let's go~ I'll take you to see the treasure of the town school of No. 1 Middle School. ”
