Let's write sentences using the words 'scratch,' 'behind,' 'scream,' 'night,' and 'inside,' with the ideas in the sentences linked together:
Last night, Lily heard a strange noise that made her scream.
She noticed it was coming from the hallway inside her house.
When she turned around, she saw her cat scratching at the door.
The sound was so loud, it startled her and she jumped back.
Luckily, it was just her cat wanting to get inside from outside, where it had been hiding behind the bushes.
In these sentences, each idea connects to the others. Lily hears the noise, realizes it's her cat, and that the cat wants to come inside. This sequence of events forms a little story using the given words.
