     Sixteen years ago, a boy gave me an important gift. It was a smile.

      It was the early autumn of my first year at a middle school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.

     Every time I heard the other students talking and laughing, I felt my heart break. I couldn't talk with anyone about my problems.

Then one day, my classmates were talking happily with their friends, but I was sitting at my desk unhappily as usual.  At that moment, a boy entered the classroom. I didn't know who he was. He passed me and then turned back. He looked at me, with a smile.

    Suddenly, I felt the touch of something bright and friendly. It made me feel happy and warm. That smile changed my life. I started to talk with other students and made friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile has become my best friend now.

    One day I asked him why he had smiled, but he couldn't remember doing so!

     It doesn't matter because all the dark days have gone. I believe that the world is what you think it is. If you think it is lonely, you might always be alone. So smile at the world and it will smile back.

    In Greek legend, Artemis is the goddess of the Moon. She takes care of the hunt and animals. In India, the god of the Moon is Soma. Soma has four hands. If a baby is born on a full moon day, Indian people believe he or she is lucky.

Schools change PE classes to help students recover* from COVID-19*.

On March 17, Beijing made changes to the PE test in the 2023 zhongkao: All students will get good scores if they take the exam. 

Some cities such as Taiyuan canceled* the 1, 000-meter and 800-meter runs. Other cities like Wenzhou let students choose if they would like to run in the exam. This is to make it safe for students after recovering from COVID-19.

Knowing about your health

At the start of the term, every student in Xi'an Jingkai No. 3 Middle School did a survey*.

●Did you get COVID-19?

"The school wants to make a plan for the PE classes according to students' health. "said their PE teacher Liu Na. "Students feel differently after COVID-19. Some get tired easily, so we keepan eye on each student's feelings. "Liu said. 

"Students in Grade Nine are happy because they don't need to take the 1, 000-meter run test for zhongkao. Most students welcome this new change. But some students are really good atrunning, they are not happy because they won't have advantages anymore, "Liu added. 

Students now are having easier exercise such as dancing, fun games, sit-ups and walking. So they can improve* their health slowly. What is your PE class like now?
