When I was a child, I often visited places with my friends. Now I bring my children with me. Apart from sighing where time has gone, the place has changed a lot. I don't know whether it's winter or long time. There are more trees and the grass on the lawn turns yellow than before. The water in the lake is very muddy, and there are fewer games to play for children, and they are basically very old, playing for 10 yuan at a time! __________
