I'm Chen Jie. Today is Sunday. I want to help my parents and grandparents(祖父母) at home. What can I do? My mother can clean the rooms, but I can't. My grandma can wash the clothes, but I can't. My grandpa can make(制作) a nice cake, but I can't. Oh, I can clean the windows. But my sister Chen Xia can't. She can sing English songs.
