what a fine day!the sun is shining and everything looks like bright.can you felt hot when you stand in the sun?the sun gives heat from far alway.it is about one hundred and fifty million kilometers away.the sun looks small because it is far from us，but it’s really very huge.

　　the earth moves around the sun.it takes one yesr from the earth to go around the sun.and at the same time the earth itself is spinning around once every twenty—four hours.

　　the sun gives us light.it keeps us warm .it makes thing grow and people need the sun.we can’t live without the sun.
