I hope talented heroes can write a speech about skateboarding for me in five minutes.

As one of the newcomers, I know that rock and skateboarding are the most popular at present. I like the rock boy sung by the rock queen Avril Ramona Lavigne, and I prefer skateboarding.

If you like a sport, you should know its history-skateboarding is an extension of land surfing. In the late 1950s and early 1960s, residents of the beach community in Southern California evolved from surfing and made the world's first skateboard. Because he is too heavy, after many improvements, a skateboarder named Frank Nasworthy installed polyurethane wheels on his skateboard for the first time, and achieved unexpected results. This flexible wheel is not only wear-resistant, but also enables the skateboard to turn safely and stably and easily run over small obstacles on the ground. The mid-1970s saw the rapid development of the third generation skateboard. With the continuous improvement of technical quality, polyurethane wheels can strengthen the adhesion friction of skateboards, improve the speed and even slide on vertical surfaces.

Skateboarding is getting better and better now, but what remains unchanged is the enthusiasm of young people for the excitement and excitement brought by this extreme sport. When I stepped on the skateboard, I felt like a friend, a friend connected with my blood. The excitement it brought me made me forget my troubles.
