Cherish what we are enjoying_2000字
It is a report about the new planet which holds possibility for life.
It shows that European astronomers have discovered a new planet, they name it Gliese 581 c.
It is about 20.5 light years from our earth. They estimated the planet's average temperature at between 0 and 40 degrees Centigrade. It is orbiting the red dwarf star, Gliese 581.
Most important of all, it’s an earth-like planet. There might be mountin, sea and liquid water.
So the astronomers believe that it is potentially habitable.
However, Gliese 581 c might be "tidally locked" to it’s sun-the dwarf star the way our moon is to the Earth.
It means that it must always show its same face to its sun, and that while one side would be too fiercely hot to support life, the other side would be too cold.
This report makes me to realize that how valuable our earth is.
Everyday, we can see sunrise and sunset.
The day and night keeps on exchanging. It’s not too hot in the daytime while not to cold at night.
Everyday, I go to school cheerfully in the morning and skip along at the way home as the sun set.
We could experience changes through the four seasons of one year.
Spring is the season sowing seeds. It is pregnant with life and green.
In the Summer, colorful swimming suits frolick in the water happily.
Autumn is the harvest season , the paddy fields and trees are covered with golden color.
In the winter，We can have snow battle, playing to our hearts' content in the world of silvery white.
How fortunate we are because we can live on the earth!
We should cherish it, instead of polluting it, spoiling it or even destroying it.
If One day, it is really angry and stop rotation, that will have be a disaster for us human being.
So, let us protect our earth with our love, making it better and more harmonious.
