The environment is the world around us, including the air, water, and land. It is where we live, play, and learn. A clean environment is very important for our health and happiness. However, our environment is facing many problems, such as air pollution, water pollution, and waste disposal. To help protect our environment, we can do many things. One of the easiest ways is to reduce, reuse, and recycle. We can reduce the waste we make by using fewer plastic bags and single-use items. Reusing things, like lunch boxes and water bottles, can also help. Recycling paper, plastic, and metal is important because it saves resources and reduces pollution. Another way to protect the environment is to plant more trees. Trees provide oxygen, which we need to breath and water bottles, can also help.

It is our responsibility to keep our planet clean and healthy for ourselves and for future generations.

The “double reduction” policy is changing the life of many students. With less homework every day and more free time for the weekend, students began to plan their own weekends. What do you think of the “double reduction” policy? Different students have different ideas. Here are some of them.

2021 is the year of the ox（牛）. In March, a set of stamps about the famous Tang Dynasty painting, Five Oxen, came out. It allows more people to know better the great art of ancient China, as well as the importance of agriculture（农业）in history.

Han Huang (723-787) was the painter of Five Oxen. He worked as a government official in the Tang Dynasty. His paintings were loved by many people because the animals he painted were so alive. Unluckily, Five Oxen is probably his only painting left.

Five Oxen is one of the best animal paintings in China’s art history. In the painting, the five oxen are in a line. They are of different colors and shapes. And each has a different appearance, walking or standing, holding their heads high or low. With lively expressions and bright eyes, the oxen show the spirit of doing hard work without complaints. As the name suggests, the painting is of the Five Oxen with no special background. It makes people focus（关注）on the oxen themselves.

The painting was missing in 1900. Luckily, it returned to China during the early 1950s. However, it was terribly broken with many holes in it. Great efforts were made to save it. Now Five Oxen, probably the oldest Chinese painting on paper, is kept with care in the Palace Museum in Beijing.
