In 1862, a ship sailed on the Atlantic Ocean. Thick fog covered the sea, and the engine broke down. The ship was hundreds of kilometres away from land. The captain tried to send a big pigeon for help, but it came back soon. Then he sent the small young pigeon Arny. Arny flew through fog and over the sea for more than four hours. He finally arrived and gave the rescue note to Billy. Billy ran to the office quickly. Help was sent to the ship at last. The captain praised Arny as the most amazing and brave pigeon. 范文 2 人物 / 动物评价（Arny） Arny is a brave and strong little pigeon. Facing thick fog and a long flight over the ocean, he never gave up. He carried the life-saving note all the way home. Though he was small and young, he finished a hard task that the bigger pigeon failed to do. His courage saved all people on the ship. 范文 3 主旨升华通用段 Size does not decide courage. Even small animals can show great bravery and take important tasks. Persistence and a strong heart can help us overcome hard difficulties and bring hope to others. 学科网（北京）股份有限公司 $
