My Identity As A Schoolmaster Has Been Exposed

Lin Mengjiao looked at Xu Cong and then looked at this question. She was stupid.

Ask her to do such a difficult question, is Xu Cong serious?

"Xu Cong, are you sure? This is the national college entrance examination question. You asked me to do the college entrance examination question?"

Xu Cong smiled at her and was very sure to let her do this question.

From his recent observations of Lin Mengjiao, Lin Mengjiao has already learned many questions, and then looking for the corresponding questions step by step is nothing but a waste of time.

Xu Cong said to her: "Try to do it first, and when you're done, show it to me. By the way, I'll give you half an hour."

Lin Mengjiao looked at Xu Cong with a faint expression on her face directly expressing her extremely sad mood at this time.

Xu Cong ignored her, always doing those questions, what's the point? Simple questions are always available, and some difficult problems must be done!

Then he said faintly: "It's useless to complain, hurry up and look at the question, you still have 29 minutes and 43 seconds...42 seconds...41 seconds..."

While talking, he still read the time.

Lin Mengjiao didn't have time to pose anymore, she shrank her neck, and immediately went to see the question.

She hurriedly fetched draft paper and pens from the side, and began to write and draw on them.

She is not like Xu Cong, who can directly use mental arithmetic calculations. After tossing for a while, she reluctantly tried to solve this problem.

When doing this question, she frowned the whole time, because in this physics question, there was not a single number, and it was all represented by letters.

untie:

Suppose the volume of the gas in the cylinder when the diving bell is above the water surface and when it is placed in the water is V₀ and V₁ respectively, and the pressure of the gas in the cylinder after being placed under water is P₁. According to Boyle's law and the conditions given in the question, we can get :

①P₁V₁=P₀V₀

②V₀=hS

③V₁=(h-l)S

④P=……

...

Finally, she finally calculated the answer: I=((ρgh/(ρ₀+ρgh))h, V=ρgSHh/P₀

After Lin Mengjiao finished this problem, she collapsed. She trembled and handed Xu Cong the process of solving the problem and the final result.

After Xu Cong took it over, he glanced at her problem-solving ideas and answers, but did not speak during that time.

Lin Mengjiao's heart touched her throat, her eyes fixed on Xu Cong.

Whether she did it right or wrong, this was the first time she challenged the real exam questions for the college entrance examination.

Soon, she saw Xu Cong nodded to her, and then she let out a long sigh of relief, and at the same time, she secretly gave her a sigh of relief!

Xu Cong put down the draft paper in his hand, rubbed her little head, and said softly, "My cutie is getting smarter."

Lin Mengjiao was very satisfied at this time, and at the same time, through this question, she was full of confidence in her future study!

At this moment, her mother Zhou Xiuyun called for the two of them to eat. Lin Mengjiao bounced off when she heard that she had food to eat.

Xu Cong looked at her excited look, and felt a little relieved in his heart.

It is still necessary to give her a little self-confidence at this time.

Only in this way, she will not waste time in the process of answering questions in the future, worrying about gains and losses.

After lunch, Lin Mengjiao took the initiative to ask for questions and was very active. When her parents came to Xu Cong's house and saw her studying so hard, both of them looked stupid.

They know what their own daughter is like, but when did she take the initiative to study?

The two of them were called by Xu Cong's parents. There are so many gifts at home, and they can't use them up. In the future, they will be in-laws to share.

"Come and come, you take these wines back." Xu Junshan said to them with a look of enthusiasm.

Looking at the gift in his hand, the two of them looked even more incredible.

"Moutai, this is, it costs thousands, or even thousands, tens of thousands! We can't ask for it, we can't ask for it!"

"Old Xu, what are you kidding about, we can't ask for such an expensive thing."

When Xu Junshan saw their refusal, he certainly couldn't agree.

So he said to Father Lin: "Old Lin, you are fighting with me like this. Take it, you must take it! Who is with whom in our two families!"

"Besides, there are many more at home, I can't finish drinking it alone."

Puff!

too much?

Can't finish drinking?

Are you still going to finish drinking?

"Old Xu, are you confused? This wine is used to treasure appreciation. Is it for you to drink?"

"Moutai can only appreciate in value, it is impossible to decrease in value."

Xu Junshan ignored the great principles he said, and said directly to him: "You can collect it for me. By the way, you have to collect half of it for me."

Xu Junshan and Zhou Xiuyun are both contented and happy people. Naturally, they will not only eat alone, and sharing with in-laws is also very good.

It is said that those who are near Zhu are red, those who are near ink are black, and the situation of Lin Mengjiao's family is roughly the same as that of them.

If everyone's personality is not like this, then the relationship between the two of them will not be so good.

At this time Zhou Xiuyun also said to them: "If you don't take it, you will be out of sight. Really, one family, what do you say about two families?"

Lin Mengjiao's parents glanced at each other and took a deep breath. There are more than 20 bottles of wine here, and one bottle is priced at 5,000 yuan, at least hundreds of thousands.

When they were thinking about alcohol, Xu Junshan said to them again: "Lao Lin, I don't smoke. You can also take these cigarettes."

The cigarettes Han Honghu bought were not packs of packs, one by one, he bought the whole box directly!

More importantly, all he bought was Huazi!

There are 50 cigarettes in a box, and after a calculation, the value of the cigarettes in this box is not cheap.

Of course, there are many gifts.

Xu Junshan was afraid that he would refuse again, so he said there, "You smoke, I know, I don't smoke, you also know, so you know."

Lin Mengjiao's parents were directly confused by him. This dazzling array of alcohol and cigarettes... are all money!

"Are you a bit too much? You all said no, you still have to give it, what do you mean? Do you show off your wealth?"

Just kidding!

Xu Junshan glanced at his wife, and then smiled at the two of them: "Yes, I'm just showing off my wealth, otherwise how can you rest assured that your daughter will marry me?"

You're kidding, I'm kidding too, the two pairs of adults just started making noise.

Zhou Xiuyun and Xu Junshan insisted on saying to the two of them: "Take it, you must take it, don't take it, I won't let you go out of this door today."

Lin Mengjiao's parents also insisted on their point of view and said to them: "Take it, it must be taken, but after the two of them are together, we don't need a cent for the gift money."

When Zhou Xiuyun heard them say this, she chuckled and said, "Then you don't regret it. It's still early for them to enter the marriage. The price in a few years will be different."

When Lin Mengjiao's father heard this, he laughed and said, "Hey, in a few years, will you not increase the price of this wine in the future?"
