初一关于动物的英语的演讲稿
答案
我最爱的动物——海豚
My favourite animal
Dear teachers and students:
Today i want to introduce my favourite animal Dolphin to us
It is one of the most precious animals.Their bodies are very long,about one zhang(丈).Dolphins live in the sea.They 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 in the past years.How helpful the dolphins are!
Dolphins are very clever.People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.
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 take actions to protect dolphins.
thanks for attention!
