Mrs. McTavish looked out. “It's a lovely day. Would you like to go for a walk in the park?" Her children   21    with excitement.

    "Before we go, you need to follow some rules. Everyone must   22   hands and  stay close to me. You can't   23   anywhere by yourself. Can you all do that?"

    All for   24   they would. As they walked down the street, Fiona said, "I want an ice lolly (冰棍）, Mummy. Can we have some?"

   "You can if you follow the rules," answered Mrs. McTavish.

   The park is just around the corner. The children ran off to   25   . After a while, when Mrs. McTavish looked up she couldn't see Jock. "Fiona, where's Jock?"

   "I don't know, Mummy. He's not here   26   ," said Fiona.

   The others hadn't   27   Jock either. Mrs. McTavish had to gather her children together and walk around the park   28   for him. She found him sitting near the ice lolly man. "Jock! What are you doing here? I couldn't   29   you."

   "Mummy, I want an ice lolly," Jock whispered.

   "You can't have one now   30   you didn't follow the rules." Mrs. McTavish   31 one for each of the other children and they licked (舔）them all the way home. Jock cried. When they   32    home she talked to Jock. "Mummy has four children. I must have rules so I can   33   an eye on you and know you're   34  ."Jock said he was   35   and he would follow the rules from then on.
