Some young Cambodians are learning a new sport — skateboarding. The country’s first skateboard park is located on the grounds of a local charity group at the edge of Phnom Penh, the capital. Sports like Khmer boxing and soccer are wildly popular in Cambodia. But Chea ，who has been skating for 6 months ，says skating has already become his favorite sport. The skaters are learning tricks like launching off a jump or half-pipe and flying through the air on their narrow wooden boards. A non-governmental organization called Skateistan Cambodia organizes weekly programs at the park. 先组字，再组词。 故____（　） 青____（　） 下____（　） 艮____（　）
