    There is a park near my home. People like to go to this park after work. Some of them go to the park every day. Look! This is Mr. King. He is sitting on a chair and watching the children. Some children are playing a game. Some boys are playing football. Lucy and Lily are standing under a big tree. They are talking about their favorite movies. There is a small river in the park. We can see some boats on the water. Some children are sitting in the boats with their parents. Listen! A girl is singing. It's really a nice park. I come here every day.

七年级（1）班，很多同学都有绰号：小田因为跑步快而被同学叫做“飞毛腿”；小刚因为长得矮胖而被叫做“武大郎”；小立因为数学优而称为“计算机”……
给同学起绰号，有人认为，侵犯了公民的名誉权；有人认为，表示对同学的欣赏和敬重。这两种观点对吗？请说明理由。
