B
China is a magnificent(壮丽的) country with a long history. It successfully held two important Olympic Games in the 21st century.
In 2008, Beijing hosted the 29th Summer Olympic Games. Many wonderful stadiums like the Bird's Nest and the Water Cube surprised the world. Athletes from different countries came to compete and make friends with each other. The 2008 Summer Olympic Games showed China's rapid development and rich culture to the world.
In 2022, Beijing and Zhangjiakou held the 24th Winter Olympic Games. Beijing then became the first city to hold both the Summer and Winter Olympic Games. Many young players tried their best and won the highest praise. The 2022 Winter Olympic Games
encouraged more people to love winter sports, such as skating and skiing.
Why did China hold these two big events? First, China wanted to show its warm welcome to the world. Second, the Olympic Games can help different cultures understand each other better. Third, they can push the development of sports and culture in our country. Today, more Chinese people take up sports and keep healthy. The Olympic spirit, "Faster, Higher, Stronger — Together", is still alive in our daily life.
