     I usually get up late (晚) on Saturdays and Sundays. I have my breakfast at around nine o'clock. I

like eggs and an apple for breakfast. I often go to see my uncles after breakfast. They're very fun. Uncle

Jim is a runner. He runs for eight hours every day. I like to run with him because it's really interesting. But

I often run with him for only one hour. I'm usually very tired after that. Uncle Bob is a movie star. He's

really busy. It's very difficult for me to see him on weekends. Uncle Bill is an English teacher. I like him,

and I like English, too.
