The doll is soft and delicate, and her skills are at the top of the 70 exam

Jiang Mengmeng ran outside after brushing her teeth.

Can I be late for class as a good student in junior high school?

Of course not!

Jiang Mengmeng stood at the door of the classroom: .......(?｀?Д?′)!!

Zhang Yuxi took a pitiful look, um, take another look, ouch, Mengmeng's expression is so pitiful, isn't it?

The chemistry teacher said with a dark face, "Zhang Yuxi, do you also want to stand outside and breathe the free air?"

Zhang Yuxi sat up straight suddenly, "No!"

Jiang Mengmeng curled her lips, she knew, she knew that being at the same table was unreliable, as expected, older children just don't like to play with younger children.

As soon as the get out of class bell rang, Zhang Yuxi ran excitedly to the door when she was bumped by the chemistry teacher who turned around and came back.

"Jiang Mengmeng, come out and come to the office with me."

Jiang Mengmeng:......

Woohoo, don't be late for class from now on.

Zhang Yuxi looked at Jiang Mengmeng sympathetically, "Mengmeng is too miserable."

Along the way, Jiang Mengmeng received sympathy from the entire first graders.

"Wooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooible? "

"You can keep your voice down, itchy skin."

"Sure enough, even if you are number one in your grade, you can't escape the clutches of Master Jue."

Jiang Mengmeng looked left and right curiously. Isn't that just called the office? Why do these students have such wonderful expressions?

Ming Dazhao had just finished class and entered the office. Before he could sit firmly on his butt, he saw Jiang Mengmeng who looked like a little tail.

Jiang Mengmeng showed eight teeth, and waved her paw at the head teacher, "Hello, teachers!"

"Pfft~" The tea in Ming Dazhao's mouth spurted out instantly.

Master Miejue looked at the big omen, and couldn't get angry, "Jiang Mengmeng, come here, finish this set of papers, when will you finish it, and when will you go to class."

Jiang Mengmeng blinked obediently, "What if the teacher can't finish the next class?"

"I can't finish it. I will do it after every get out of class until I finish it." The chemistry teacher said angrily.

Jiang Mengmeng, who was thinking about fishing, shrank her neck and said, "Okay."

Ming Dazhao came over curiously with a tea mug in his hand, "Old Liu, what is Jiang Mengmeng doing in class?"

Has his chance come?

The eyes of the head teacher who had long wanted to separate Jiang Mengmeng and Zhang Yuxi were shining.

Liu Wen said with a dark face, "It's nothing. She's just fifteen minutes late for class and still hanging around outside. You just dote on her too much. Although she is a little genius, she should behave like she is in school."

Ming Dazhao was taken aback for a moment, and then put on a straight face. Being late is not serious, but it is serious if you are late and wandering outside.

"Jiang Mengmeng, do you have any objection to Teacher Liu's words?"

Jiang Mengmeng raised her little paw, "Yes!"

Then the little fat man started to get serious, and said very seriously, "I didn't mean to be late, I wanted to be late because of chemistry problems."

Ming Dazhao raised his eyebrows, "Oh, then tell me, what are you thinking about?"

Jiang Mengmeng pursed her lips, "Why is the natural rubber latex collected from the Brasilian rubber tree made into an elastic solid after coagulation and drying?"

"Also, what is the composition of natural latex? Can it be synthesized artificially?"

Liu Wen was taken aback, why didn't she understand?

What is natural silica gel?

Ming Dazhao met Liu Wen's eyes and coughed lightly, "When you go to high school, you will know these problems. Now you should put yourself in the right posture, and it is right to study hard."

Jiang Mengmeng's big eyes twinkled, and she nodded obediently, "I'm sorry, Teacher Liu, I won't be late for class next time."

Liu Wen waved her hand in embarrassment, "Take the paper back and do it, and bring it back when you finish it."

Jiang Mengmeng's eyes lit up, "Thank you teacher."

As soon as the words fell, Jiang Mengmeng twisted her little butt, and ran back to the classroom with the papers soaked.

Liu Wen sighed, "My knowledge is limited, so I can't teach her."

Ming Dazhao laughed awkwardly, "She is very smart, but she still needs someone to guide her in dealing with others."

Liu Wen didn't say a word.

At noon, Jiang Mengmeng handed in the test paper and ran to the school gate.

"Nai, give me the rice. I'll take the bowl back later. I don't want you to go to the cafeteria with me to eat today." Jiang Mengmeng said cheerfully.

Xu Cuihua worried, "Can you eat it alone?"

Jiang Mengmeng nodded, ran away with the rice in hand, "It's done, it's done, please go back quickly."

Xu Cuihua was thinking about her feet and shouted, "Run slowly, there is soup in it, don't spill it."

In the corridor of the classroom, teenage students smelled the fragrance and smirked, "Jiang Mengmeng's parents are also very kind to her, and they bring food every day."

"Yes, yes, we all serve pickled vegetables with rice, and she serves meat with rice. I don't know how much meat there is in her house every day."

"You say her family is not a landlord, do you?"

"Don't talk nonsense. I think it's because she's young and her family feels sorry for her."

"It's a bit small. I heard from her classmates that she is only six years old, not even eight years old. Look at us, we are all in our teens."

"Hey~ What kind of news are you talking about? I heard that her father is a worker in a car dealership, and her mother is a waiter in a movie theater, which is the latest movie theater."

"Wow~ Then she died of happiness? Can she see celebrity posters every day?"

The envied Jiang Mengmeng is currently researching with contact lenses.

"Dabao, you said this is a semi-finished product? Can't it be used?"

Dabao nodded, "The inside is made of natural rubber condensed from the Brasilian rubber tree, so it cannot be used on the eyes."

Jiang Mengmeng blinked, "Uh, I think this one is quite soft."

Dabao pursed his mouth, "The materials of soft contact lenses are mainly divided into two types: hydrogel and silicon hydrogel. Both hydrogel and silicon hydrogel are organic high molecular polymers with strong hydrophilicity, which are soft and easy to deform. , it is more comfortable to wear, and the natural gum condensed on the Brazilian rubber tree is hard and will damage the retina, but it is more suitable for materials, such as your modified radio.”

Jiang Mengmeng's eyes lit up, "I'm considering using tapes and CDs, is it okay to use them?"

Dabao thought for a while, "CDs only came out in 72, and the price is very expensive. The chuck your father gave you cost a lot of money. Now there are radios that play tapes and CDs in foreign countries. Although they are not popular in China, if It's too expensive to be good for widespread use."

Jiang Mengmeng was stunned, pouting her rosy little mouth, "I actually have it."

Dabao sighed, "Mengmeng, don't get lost, what you are releasing now is considered a technological update, speeding up the pace of scientific research, although there is no such thing in China now, but after a long time, someone in China will definitely research it, but every minute and every second wasted is worthless." It’s money, and even your organization will spend a lot of money buying things, so don’t get discouraged, you’re helping the organization take the pressure off.”
