阅读选择填空 long long ago,people thought that the sun went around the earth求详解.
A long time ago people thought that the sun went around the earth.In some countries people even said that the sun was a god(神).They thought the god drove across the sky each day on a golden horse.
Now we know the earth goes round the sun.It takes the earth a year to go all way round the sun.Today
men even know how far it is for the earth to go round the sun.They tell us that the earth travels over a thousand miles a minute on its journey round the sun.
