Here's a short story:

Sarah is a girl. Sarah has one brother. Sarah's brother's name is Timothy. Sarah has one sister. Sarah's sister's name is Annabelle. Their last name is MacGregor. One day Sarah went to the park with her brother Timothy. They swung on the swings for a short time. Then Annabelle came out and swung with them. They all sang some nice songs together. They all became very happy. Then Timothy's friend came. Timothy liked his friend very much. Timothy went off the swing and went away with his friend. Then Annabelle and Sarah felt very very sad. Happily then Annabelle and Sarah's friend came. Their friend's name was Kate Smith. She was the same age as Sarah. They wanted to go to the slide together. So they went to the slide and played for a long time. Then Annabelle became happy. And Sarah also became happy. Then they went home together and had some food. (End of story)
