Once upon a time there was a little mother duck. She was excited. Her five eggs were finally going to hatch. She watched and counted as one by one the eggs hatched. "One duckling, two ducklings, three, four, five ducklings", she said happily. Suddenly she noticed that there was one more egg. It was bigger and whiter than the rest. "This cannot be my egg", she thought. Slowly the big egg began to crack and the strange looking duckling came up. Mother duck was surprised. The younger duckling was great and bigger than the rest. "How ugly the little one is", she thought. As the day went by, the ducklings began to grow, but the younger duckling looked different from the rest. Everybody looked at him and said, "There goes the ugly duckling". His brothers, sisters teased him all the time. The ugly duckling felt very bad. Whenever people laughed at him, he used to run away and hide behind the reeds near the lake. "Nobody loves me", he thought. One day, the duckling decided to run away from home. He swam and swam, and on his way he had many adventures. 3. Practice - Luyện tập
