B: She is

快乐的一天
It's fine today. The sun is in the sky. Mr. Green and his family are in the park. Mr. and Mrs. Green are standing trader the tree and looking at their children. Ann is flying a kite. The boy in a white shirt and blue trousers is her brother. He's reading a book. Ann's little brother is too young. He can't walk or run. He's drinking milk. Ann's sister isn't in the park. She is at school.
—OK!________
It's 6:30 in the morning. I'm running around the park. Look! There are so many people here. Linda is doing morning exercises. Linda's brother is walking his dog. Little Tom is playing football with his friends. A big boy is listening to music under the tree. A man is cleaning the road. What are the old women doing? They are dancing! What a busy morning!
