"How are you?" is a nice question. It's a friendly way that people in the United States greet each other, but "How are you?" is also a very unusual question. It's a question that often doesn't have an answer. The person who asks "How are you?" hopes to hear the answer "Fine", even if the Derson's friend isn't fine. The reason is that "How are you?" isn't really a question and "Fine", isn't really an answer. They are simply other ways of saying "Hello!" or "Hi!".

    Sometimes, people also don't say exactly what they mean. For example, when someone asks "Do you agree?". the other person might be thinking, "No, I disagree. I think you're wrong. "But it isn't very polite to disagree so strongly, so the other person might say "I'm not  so sure. "It's a nicer way to say that you don't agree with someone.

    People also don't say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person says "I have to go now. "Often, the person who wants to hang up gives an excuse: "Someone's at the door." "Something is burning on the stove. "The excuse might be real, or it might not. Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't polite to say that. The excuse is more polite, and it doesn't hurt the other person.

    Whether they are greeting each other, talking about an idea, or finishing a talk, people often don't say exactly what they are thinking. It's an important way that people try to be nice to each other, and it's part of the game of language.

 "Turn left! Turn right!" In the information technology(IT) class, Zhang Ruixuan was controlling a robot to move around.

"This is part of our artificial intelligence of (Al) courses," said the 10th grader from Beijing 101 Middle School. The school provide AI classes to both junior and senior high school students. Apart from compulsory(必修的),courses that teach basic knowledge, there are also optional(选修的) courses if students want to learn more.

"This semester of compulsory class, we have learned coding(编程) through a programming language called Python," said Zhang. Using Python to code is an elementary skill for training AI models. In recent years, Python has been tested in high school graduation exams in places like Beijing, Jiangsu and Anhui.

In fact, having Al education in schools has become a growing trend(趋势) in many places, with Zhejiang Province being a typical example. In 2020, Zhejiang added AI education into textbooks from Grade 5 in primary school all the way to senior high school. In the city of Wenzhou, the government is planning to build 1,000 AI experimental schools by 2025.

"With the development of technology, our textbooks have been changing all the time,"said Shang Yin, an IT teacher from Beijing 101 Middle School."From typing to using Word and Excel, and then today's coding and AI, the courses are keeping up with the times and teaching students necessary skills. In the future, there will be more jobs where AI knowledge is required.Even in daily life, people may need to understand things like ChatGPT and the Internet of Things. AI education will become increasingly important," Shang added.

Recently, a video game named Black Myth:Wukong has been a great hit all over the world. Black Myth is China's first AAA video game. Why is it so popular? It is the Chinese culture inside it.

Wukong is a main character from Journey to the West, a Chinese classic god- evil novel written 500 years ago." Chinese god- evil stories are fantastic themselves. No one would dislike them once they start to learn about them. And my game just opens a window." Said Feng Ji, the game's producer. For this reason, although players from other countries were not fans of Chinese culture, they are now" hard- working" on every detail of the novel. For almost the first time, the world tries actively to understand Chinese culture.

The beautiful scenes in the game are also attractive. Among the 36 places that appear in the game, 27 are real in Shanxi Province. Take the Hanging Temple for example. It was built nearly 1,600 years ago and truly hangs on a steep cliff(峭壁). Players are amazed when they realize it is a true attraction.

An American player said," China is rich in culture and stories. I hope we can get more like this. I would love to go to China some day."

Today, more and more parents ask their children to play sports every day, because they worry about their children's health. They want to know more ways to help children keep healthy. 

Being healthy means a person eats well and gets enough physical exercise. If you are healthy, your mind works well and feels good. Here are some rules you can follow to keep healthy. 

Eat all kinds of foods. You may have your favorite food, but it is important to eat all kinds of foods. Try to eat least five kinds of fruits and vegetables a day, two fruits and three vegetables. 

Spend less time on screen. Some children spend much time watching TV, playing computer games or using smart phone. These three sitting down activities are really bad for your health. Try to spend no more than two hours a day on screens. 

Be active. You need to find what activities you like as a child. Not everyone loves baseball or soccer. Maybe your favorite is swimming or dancing. You can write down the enjoyable things when your mom says it's time to stop playing computer games!
