     Mr Jones has a special way of waking Lily in the morning. He sends Lily's dog, Frank, into her bedroom.

Frank jumps up and licks (舔) Lily's face, then Lily gets out of her bed. That's how every school day starts.

     One Monday morning, Lily got out of bed and looked at the clock. It was 6:45. Lily washed and dressed.

She moved quickly. She knew she didn't have much time to get ready for school. The school bus usually stops

at the corner of her street at 7:30. She has to be at the bus stop by then.

      "What's for breakfast?" asked Lily. Her father gave her two eggs and a glass of orange juice.

      "Hurry up," said Mr Jones."Where's your homework? Do you have that note I gave you for Mrs Brown?

Don't forget it. Here's your lunch money."

     Lily got her books and homework all together. She found the note and took the lunch money. She put

everything in her schoolbag. Then she rushed off to catch the bus at 7:30.

     The bus was right on time. Lily got on and sat down next to her friend Bill. Then Lily and Bill started to

tell each other jokes. It was nice to relax.
