Characters: Xiao Liu, a middle school student in 2 1 century; Liu Wei, a middle school student in 2 1 century; Su Kai, a middle-aged female teacher in 2 1 century. In the computer is a middle-aged female teacher who is giving him a physics class. China: OK, please describe Newton's first law. Shaw: Newton's first law is the law of mass invariance. China people: Wrong, Xiao: Alas, I just can't remember this physical concept. English: Please turn the desktop home page to the next page. Xiao: What are you going to do? [Xiao Liu clicks the mouse. Hey, I'm writing a composition again. (Reading screen) A short scientific essay "2 1 century in my mind". How to write this article? -the requirement is to look forward to the future in the middle of this century in combination with reality and imagine it reasonably. The word count is 1000 words, which is saved in the following documents and sent to the following websites ... [Xiao Liu turns off the computer angrily. ] Xiao: so boring, I won't attend today's class! Well, I can find my classmates to play with. Who can I find? Let's go find Su Kai! [Type the keyboard and enter the phone number. In an instant, Su Kai appeared on the screen. Xiao: Su Kai, what are you doing, so devoted? Sue: Xiao Liu, I signed up for the World TV Innovation Competition. After several rounds of elimination, I have entered the finals! Shaw: Great. What kind of innovation are you making? Sue: My topic is "Improving the efficiency of solar cells". I added a newly developed substance to silicon crystal, which improved the efficiency of solar cells by 50%, and was only 1 percentage point away from the theoretical limit of solar cell efficiency. Xiao: You are really something. You are really capable. Get ready. I won't bother you. Sue: When my game is over, I will definitely have a FIFA2050 game with you. Goodbye! Xiao: Goodbye, who am I looking for now? Yes, Qiu Yun! [Type the keyboard and enter the phone number. After a while, autumn rhyme appeared on the screen. Xiao: Qiu Yun, this is Xiao Liu. With you; Have you ...? You don't want to take part in any innovation contest! Qiu: Innovation competition, no, no, no. I am writing a biology paper "Sewage Purification". You see, I have cultivated some bacteria, and this cup of sewage has been treated by these bacteria and turned into a cup of pure water. Xiao: Wow, you are going to be a female biologist. Qiu: Yes, this is my ideal! Xiao: It seems that you are also a busy man. I can only say goodbye. Qiu: Goodbye. Xiao: I'd better go to Liu Wei, but I can't make a phone call this time. Send an email! "Liu Wei, please come quickly, little Liu Yi" OK! Liu: Hero Xiao, what's the matter? You need me so badly. Xiao: I'm looking for Su Kaihe. They are all busy preparing for the game. You are the only friend who can come in a short time. Alas, Liu Wei, have you finished your composition? Liu: I was just about to write a letter when your email dragged me over. Do you want to play basketball? Xiao: That's my buddy. You guessed it. Let's play ball. [Suddenly the computer said: Xiao Liu's father has an instruction to turn off the computer for 15 minutes, and then it will automatically turn on the computer for class. ] Liu and Xiao: No way! Xiao: (wry smile) No way, planned economy. A woman doctor appeared on the computer screen. Hello, I'm the new teacher. Xiao He Liu: Hello, teacher. W: Do you want to be super smart? Xiao: Even in my dreams. W: Do you want to gain endless knowledge without studying? Liu: I am dreaming! W: It was impossible before. It was wishful thinking. Xiao Liu: What about now? Woman: Please put on the brain wave input device first and aim the electrode at the temple. Woman: Well, as long as you tell me a name, I can make you have his thinking. Shaw: (eagerly) Newton, saxophone Newton. Woman: There is no such person. Liu: It's Isaac. Newton. Shaw: Yes, Sir isaac newton, I want to be as clever as him! Woman: DuDu ... [Xiao Liu turned around with a buzz in her head. ] Liu: Who are you? Newton? Xiao: No, I'm a talented scientist Xiao Liu, but I'm just like Newton. Haha, Liu: No way. You never passed the physics exam. Let me test you. Tell me about the three laws of Newtonian mechanics. Shaw: Newton's first law is the law of inertia; Newton's second law is f = ma Newton's third law is the law of action and reaction; And the law of gravity F = G (m+m)/R2 ... Liu: Oh, my God, the physical difference has become Newton! Xiao: I found all these poor students. How could I not know? Liu: (excitedly) Well, lend me the brainwave input instrument quickly. Xiao: (at a loss) What ... lost ... equipment? Liu: Don't play dumb, genius, brainwave input device. Xiao: I still don't understand ... Liu: Is he really a medieval Newton? That's not genius. (Pointing at the computer) What is this? Xiao: I haven't seen this before. I need to study it carefully. Liu: (gloating) Haha, what genius, who doesn't even know computers, is more stupid than a poor student studying physics? (Pointing at the apple) Sir Newton, what is this? Xiao: It's an apple, it's an apple: (Passion) It falls on my head, it inspires me, it is the founder of gravity! Liu: Newton, who only knew Apple, really became a medieval man. What can I do? Get out of here! [Liu Wei repeatedly hits the computer] Female: DuDu! DuDu! DuDu! Xiao: Just now ... what happened ... like a dream. Woman: I just put Newton's thinking code into your head. Although I made a joke, after I corrected it again, you now have great wisdom in ancient times and extensive knowledge of young people now. Xiao Liu: Yes! [Two hands high-five. ] female: I am a high school student in 1999. I participated in a golden key competition and wrote a composition, my heart.
