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.

Recently，teenagers face many kinds of problems.Like many of them.I was once troubled with worries and dissatisfaction.Few people could understand my feelings.（1）
"The problem with your generation is that you always expect to be happy，" my mother once said.（2） Shouldn't we try hard to achieve it？
But now I have noticed a change in my thinking.I gradually realize what my mother said was correct.Over these years，many studies have shown that we are crazy about happiness and high personal confidence（3） In fact，we may often be happier when we stop focusing on happiness.
We should also reset our expectations of the future.Don't expect miracles（奇迹），and accept that no matter how hard we try，feelings of failure and unhappiness will appear from time to time.When we feel sad，it's often because we have learned something painful but important.（4） At the same time，we should learn how to deal with them better than trying to make them disappear.

A.Neither could my parents.
B.We should keep the stress off ourselves.
C.Surely happiness was the purpose of living.
D.That may make us less satisfied with our lives.
