Dolphin is my favourite animal.

 It is one of the most precious animals in the world. Dolphins’ bodies are very long. They live in the sea, and live on fish, shrimps and so on.

Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger. People train them so that they can give a dolphin show. And they often bring people a lot of happiness and joy. How helpful and clever the dolphins are!

Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. As a student, I hope more and more people can take actions to protect dolphins
