The Beijing 2022 Winter Olympics was a great success. China has kept the promise to hold a green Olympics. Many green actions made it possible, like providing environmentally friendly smart beds, using new energy(能源) cars, supporting sporting places with 100% clean energy and reusing rain and snow water.
Take making ice as an example. China didn’t use R507, a common material to make ice, because it isn’t friendly enough to the environment. Through 18 months’ hard work, China independently developed the CO₂ direct cooling technology.
A net of tubes runs under the ice. High-pressure liquid(液态) CO₂ goes through them to create heat(热) exchange. The CO₂ evaporates(蒸发) under the ice surface. The evaporation takes in heat and turns water on the surface into ice. And the CO₂ goes into another circle. This technology helps to make ice better and faster. And above all，it is much greener because there’s no new CO₂ produced. Among all the 15 ice sporting places in the Winter Olympics, 7 used the CO₂ direct cooling technology to make ice. As a result, much less pollution was caused.
Beijing did so much more to save energy. Beijing built the new sporting places with green materials. As for the old ones, Beijing used new glass walls to take the place of traditional walls to let more natural light in. 70% of the waste heat was also reused to keep warm and dry. And a large number of new energy cars were used at the Beijing 2022 Winter Olympics.
The Beijing 2022 Winter Olympics is the first to truly achieve carbon neutrality(碳中和), and it has set new standards in green technologies. Some newspapers say China has set an example for the world in environmental protection and green development.

Free time is a good chance for teenagers to have fun. What about free time with parents around? Some teenagers want free play without parents’ supervision(监管) while parents and experts(专家) may think differently.
Lin Tao, a middle school student, thinks teenagers should be free to play. “Last time I played with my parents around, I was nervous and just couldn’t enjoy myself to the fullest,” Lin says. “And my friend Chen Xiaoxin has similar experiences. Once, he went out to play with his classmates. Everyone felt uncomfortable with his mother’s supervision.”
Wang Min, a mother of a 14-year-old boy, thinks playtime needs supervision. She explains, “People usually say I like to control my kid, but that’s not true. I am just worried that he will get into trouble. Some guys may have a bad influence on him and some games like LARP(剧本杀) may mislead him. He might even get indulged in the stories and can’t get back to real life.
Mr. Ma, a doctor of social studies, says it’s understandable for teenagers to wish for freedom. Free play helps them to be independent. Parents can give them more space. They don’t have to supervise them all the time. However, teenagers should find out the exact details(细节) about the activities before playtime. Then they can communicate with their parents and decide together whether they can go out to play alone.
