三、范文... My pet is a cute dog named Coco. She is also my best friend.开篇总领全文，引出宠物并强调友谊。Coco is small and fluffy. She has a white coat that looks like soft cotton. Her big, bright eyes are like shiny black gems, always looking at me curiously. And her short tail waves happily whenever she sees me.从整体形象到局部特点，全面描写狗狗的外貌。Coco loves playing with balls the most. She will run around the yard, chasing the ball excitedly. She also enjoys taking walks with me. When we are out, she sniffs everything along the way, as if exploring a new world. Sometimes, she likes to lie beside me quietly, listening to me talk or just taking a nap.利用现在分词短语、状语从句，生动地展现狗狗的行为。I really love my little dog Coco. I think she is the best pet in the world.
