Today is Sunday. The Browns are on holiday in Hainan. They're at the beach now. It's sunny and windy today. The clouds are white and the sky is blue. Mr. Brown is swimming in the sea. Mrs. Brown is enjoying the sunshine. Bob and Mary are collecting shells on the beach. There is a windmill near here. It stops. Some birds are standing on it. Who is that old woman? Oh, she is Mary's grandmother. She is cooking lunch for them.
