After a little girl named Betty heard the radio, she and her family went to the rocks in the mountains to look for swallows.
Betty walked up the hill step by step. Suddenly, she saw a frozen swallow under a tree, so she immediately stepped forward, gently picked up the swallow with both hands and put it to her mouth, trying to warm it with her breath.
Betty saw another cave. She quickly carried the swallow into the cave. After entering the cave, she found some frozen swallows. She thought, I can't let these swallows catch cold any more, so she took off her coat and wrapped them in spite of the cold.
Betty walked out of the cave and went straight ahead, continuing to look for frostbitten swallows. After walking for a while, she didn't see the frostbitten swallow, so she walked up along the crack in the rock in the mountain. As she walked, she found some injured swallows.
With Betty's unremitting efforts, she saved more than a dozen swallows at the end of the day. Her behavior made many people admire her. What a caring little girl she is!
