Сам текст:  
    Father Elephant and Mother Elephant lived in Africa and they had a little Baby Elephant.
    One day Father Elephant asked, "Why are you sad, my little Baby Elephant?"
    Baby Elephant said, "Oh, Dad, I want to play in our school football team. But my socks, T-shirt and shorts are too small and I can`t put them on. "Don`t worry, my dear!" said Father Elephant. "I`ll buy you nice new clothes." 
    They came to Mrs Lion`s shop.
    "Good morning, Mrs Lion," said Father Elephant.
    "Good morning, Mr Elephant!" said Mrs Lion. "Can I help you?"
    "Have you got any nice socks for my little Baby Elephant? I want to buy him some new socks," said Father Elephant. "All our socks are too (слишком) small for Baby Elephant. But wait (подождите) a little and my little Lions will make him new beautiful socks."
     The little Lions made nice new yellow socks for Baby Elephant.
     Then Father Elephant paid (заплатил) for the socks and put then on Baby Elephant.
      Baby Elephant was very glad, and he said, "I like my new socks very much, than you." "Let`s buy you a new T-shirt and shorts now!" said Father Elephand. So they went to Mrs Tiger`s shop.
