most precious animals. their bodies are very long. they live in the sea. they live on fish, shrimps and so on. they are very clever. people often train them，so that they can give it show which brings people a lot of happiness and joy. they are very friendly and peaceful. they never attack people. instead, they have saved many people in danger in the past years. how helpful they are! can you guess its name now? yes, you are right. they are dolphins. however, unluckily, the number of dolphins is getting smaller and smaller. because of water pollution, there is less and less space for dolphins. many people make money by hunting dolphins. if we don’t protect them，maybe we’ll lose our good friends one day. as a student, i hope more and more people should protect dolphins. i love dolphins very much. and i hope dolphins are our good friends for ever. i hope they can live in the blue sea happily and peacefully. let’s protect the animals together. let’s take actions. ……………………
