Dear teachers and schoolmates, good morning!
My topic is “We have only one earth."The earth is a beautiful pearl in the universe. In the past, the earth is like a fairyland, clear water andblue sky, green trees… But now, the earth had lost her beauty, the people can not help but think: That is why?
Listen, there are no more trees and birds in the forest but the sound of powerful saws. Trees were cut down and animals lost their homes. The clear water became dirty, with no fish.If this goes on, we can not get fresh air. There will be no water to drink, no place to live.We should save water and electricity, and don't pour waste water into the rive. Plant more trees to make the earth mother put on green coat! Bebeautiful like before
Dear schoolmates, for our homeland, for the clear water, blue sky, green and red flowers. Let us join hands together to protect the earth, because we have only one earth.
That's all, thank you.
