The World in My Dream（≈I have a dream ,对吧）
As we all know,Martin Luther King had a dream.He wished people of different colours and from different classes to share the same rights.
I also have a dream and the world in my dream is a place full of love,where there are no wars,no viruses and no pollution,where the sky is blue,the rivers are clear,the mountains are covered with green trees,birds can sing happily,where children can play to the bottom of their hearts and people live in harmony with animals.
To my dream,I will devote all my life.
For my dream,I will spare no efforts.
Above all,I believe each of you will help me,won’t you?
