Feathers are made of a tough protein called keratin, which is also found in hair and nails. Birds have to constantly maintain their feathers by preening and replacing them periodically.
Here are a few example sentences:
"The peacock's feathers are so vibrant and beautiful."
"The bird's feathers were ruffled by the wind."
"The feathers on the bird's wings were perfectly symmetrical."
中文翻译:
"孔雀的羽毛非常鲜艳美丽。"
"鸟儿的羽毛被风吹乱了。"
"鸟儿翅膀上的羽毛完美对称。"
