Bicycles are still popular in Beijing. Some people go to work or go to school by bike. Because it is easy to go to work or go to school. But at the moment, many people buy cars and go to work by car. It makes the air dirty and it's not good for people's health. Although taking the car is fast, I like riding a bike better. Because it can help me keep in good health. And we can save more energy. I think riding a bike is a way of doing exercise, and doing more exercise can help us get good grades.
At last, I hope everyone can ride bikes to go to work. Because it can make our world more beautiful.
