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.

A while later they saw mice running out, one after another，but they saw two mice didn’t run away immediately. It seemed that one was trying to bite(咬) the tail of the other.
Everyone was puzzled, so they came nearer to take a look. They realized that one of the two mice was blind, and the other was trying to allow the blind mouse to bite his tail in order to pull the blind one with him to run away.
During the meal time, they started to talk about the two mice. One serious American said, “I think the relationship between those two mice was that of king and guard.”
A smart Frenchman said, “I think the relationship between them was that of husband and wife.”
A Japanese said, “I think the relationship between them was that of mother and son.”
At that moment, one Chinese asked, “Why did those two mice have a certain relationship?”

Many years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn’t wash her window. It really looks terrible.”
One morning I cleaned my room, including washing the window on the inside.
Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly seen. Her window was clean!
Then it dawned on me. I had been criticizing(批评) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. Since then, whenever I wanted to judge(判断) someone, I asked myself first, “Am I looking at him through my own dirty window?” Then I try to clean the window of my own world so that I may see the world about me
