I have a dream
Everyone may have his own dream.Someone may want to be rich,someone may want to be beautiful,and someone may want to have power.But I’m different from them.My dream is special.I want to have a pair of wings and a clear sky.Because I want to fly in the sky,I like the feeling of freedom.
Once man did not have to think about the protection of his environment.There were few people on the earth,and natural resources seemed to be unlimited.
Today things are different.The world has become too crowded.We are using up our natural resources,and polluting our environment with dangerous chemicals.If we continue to do this,human life on earth will not survive.
We realize that if too many fish are taken from the sea,there will soon be none left.Yet,with modern fishing methods,more and more fish are caught.We know that if too many trees are cut down,forests will disappear.Yet,we continue to use powerful machines to cut down more and more trees.We see that if sky is polluted with waste products,we will die.Yet,waste products are still fly into sky.
If we protect our environment and I have a pair of wings,I’m sure it will be very wonderful.I can fly below the blue sky with the birds.I can enjoy the music of birds’.I can fly across the cloud and the small wind will blow past my face.The feeling must be the same as that my mother caresses me.
I can fly over the sea,below the rainbow,through the forest I can see all the wonderful view.But I know that it will never be uteri have another instead.I want to have a fly of my own.The plane must be very small and light.It has to carry only one person.It can fly by wind or sunshine.It can fly for a very long time.And the important thing is that it must be very save.
I’m sure I can have this plane some day.And I can have fly to everywhere I want.
So we should protect our environment,protect us one and only earth!
