同类题1

Do you have an English name? I have noticed (注意到) one thing in China: lots of people have uncommon(不常见) English names.

One of my Chinese friends calls herself Big Bird, like the character(角色) from the children's TV show Sesame Street(《芝麻街》). Another one of my friends is an English teacher. She had students with the names like Tomato and Potato. There were also two girls named Echo. Before I came to China, I had never met anyone with these names.

People choose these strange names for different reasons. Sometimes they copy the names from someone famous. Other times, they want names that have the same meaning as their Chinese name.

But having an uncommon English name isn't a big deal, is it? It can be fun sometimes. I once heard about a girl named Shmily. It stands for “see how much I love you”. It is my favorite strange English name.
