Mother ： What for？

　　Son ： To feed the monkeys.

　　Mother ： No. Feeding is forbidden here.

　　Son ： Why？

　　Mother ： Because it spoils the animals.

　　Son ： Is that true， Daddy？

　　Father ： Yes， and sometimes the monkeys may have digestion problems if they eat too many peanuts.

　　Son ： It won't be any fun if I can't feed them.

　　Father ： This zoo is huge. It may take four or five hours just to walk it through.

　　Mother ： Do you' think little Tommy can walk by himself that long？

　　Father ： I don't know， but I certainly won't have the strength to carry him in my arms when be gets tired.

　　Mother ： What should we do then？

　　Father ： They have baby carriages for rent at the entrance.Shall we get one for little Tommy？

　　Son ： I don't need a baby carriage. I'm three years old now. I can walk by myself.

　　Mother ： I know you can， but just in case. OK？

　　Son ： OK.
