Parents are the closest people to you in the world. But a lot of middle school students have a problem. They feel they're not as close to their parents as before. They even don't think their parents are fair (公平的) to them.
Some students complain that their parents often say a lot to them, but never listen to them. Some say their parents don't allow them to play computer games when other classmates are doing that. Others say when they're making phone calls to friends, their parents like to ask if they're speaking to a boy or a girl. These make them very unhappy. Some students even decide to leave home because they're afraid to tell their parents when they have done something wrong, especially when they do badly in exams. Then they usually think running away is the only choice (选择). But they don't know running away may bring them some more problems.
Problems are parts of life. Here are some suggestions for you to solve your problems.
1) Find a good chance to talk with your parents. Don't be afraid to tell them your feelings.
2) Get help from others like good friends or teachers.
3) Keep a diary to help you understand more about yourself and your feelings.
4) Show your parents you're growing up. Then they'll feel you're no longer a small child.
What's the most popular Winter Olympics design with kids and teenagers? It must be the mascots (吉祥物). Bing Dwen Dwen, a panda in an ice shell, was chosen as the mascot for the Beijing 2022 Winter Olympics in 2019. Now it has been made into lovely toys and models, as well as printed on notebooks, bags, and so on.
"The International Olympic Committee (国际奥组委) has found that successful mascots had to be cuddly (令人想拥抱的) and liked by 9-year-old children, " said Cao Xue, one of the designers of Bing Dwen Dwen. "And I knew Bing Dwen Dwen would be. "
Cao's team once made three designs, and Cao asked his 9-year-old son to choose his favorite. "When he first saw it, he chose Bing Dwen Dwen, which was the final mascot, " Cao said.
Cao's team tried many plants and animals, finally going with a panda. "What can better stand for China than our national treasure (宝藏)?" said Cao, "We don't need to say anything to have it understood across different cultures. "
They faced a problem, though, there were already too many cartoon pandas. Cao's team looked at panda designs from around the world. They wanted to make sure their panda was different. For this reason, Cao thought that it should be a baby panda. This is how they got Bing Dwen Dwen's body shape.
Bing Dwen Dwen looks like an astronaut in a space suit. It waves its left hand to say hello. It has two red hearts on its hand, showing kindness and love. A series of colored floating lines around its head look like the tracks on an ice rink (冰场). They refer to "Ice Ribbon (冰丝带)", which stand for Beijing's National Speed Skating. The colorful lines also refer to fast 5G signals.

What should you do if there is a fire at school? Do you know how to protect yourself in a large crowd? Every year since 1996, on the last Monday of the last week in March, the National Day of Education on the Safety of Elementary and Middle School Students (全国中小学安全教育日) is held. This year it falls on March 28th. It offers us a chance to learn more about school safety.
A survey shows that the worst accidents are a result of stampedes (踩踏), fires and traffic. When facing an accident, the first and most important rule is to stay calm. But you should have different ways to deal with different accidents.
A stampede happens in a place where there is a large crowd. When students around you begin to push, stand still and try to hold on to something, or stay in a corner until the crowd leaves. If you fall down in a moving crowd, cover your head with both hands to protect yourself. Lean to one side, curl your body and bend your legs.
When there is a fire, you should follow the teachers' instructions. Leave the classroom and use a piece of cloth to cover your mouth and nose so that you don't breathe in smoke.
If you walk to school or go by bike, follow traffic rules. Wait for the green traffic light, and look left and right for cars before you cross the road.
