Read the story Sadie’s Talent by Lloydene Cook. For questions 1-6, choose thecorrect answer (a, b or c).
Sadie was the youngest child in the family with lots of talents. Her papa was the Pig Calling Champion. Her mama sewed perfectly. Her brother, Buster, could stand on his head. Her sister, Clorissa, could sing better than a bird on a sunny morning in May. Sadie liked making up stories in her head, but she was shy and didn’t share them with anyone.One summer afternoon Sadie sat near the house. She was upset. “What’s worrying you, Sadie?” asked Grandma.“Everybody does things better than I do,” Sadie said.“I think you haven’t found you gift yet,” Grandma said.“What gift is that?” Sadie asked.“Everybody has a gift,” Grandma explained. “Something that makes you special. You haven’t found your talent yet.”“How do I find my talent?” Sadie asked.“Look inside yourself,” Grandma said.“And how will I know if I find it?”“You will feel special all over,” Grandma said.And Sadie looked. She sang with Clorissa. She sewed with Mama and made pies with Grandma. But Sadie didn’t feel anything.One night after supper the family gathered in the yard. Mama was sewing, Grandma was shelling nuts and Grandpa was making a toy alligator. Clorissa was singing a new song and Buster was standing on his head.Grandma said, “I remember how my mama told me stories – best stories I ever heard.”Sadie said quietly, “I know a story, Grandma. Far back there lives a big old hairy monster. Every night he comes out and looks for something to eat …”When Sadie told her story, everyone stopped to listen. Clorissa and Buster sat down near Sadie.“People tried to catch the monster, but he always went away. Some people say he’s still walking in this forest at night, hungry for his supper!”Buster said “That was a good story.”“Tell us another one. Please!” Clorissa asked.Sadie smiled at Grandma. “Once upon a time…”
