阅读理解
A long time ago, people thought that the Sun went round the Earth. In some countries people even said that the Sun was a god(神).They thought the god drove across the sky every day on a golden(金色的) horse. Now we know the earth goes around the Sun. It takes the Earth a year to go all the 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 (英里) a minute on its journey round the Sun.
The Sun is really a star. It is much bigger than the Earth. And it is very hot. Some people have been to the Moon, but we know that no one can ever go to the Sun. It is too hot for people to live anywhere near it. The Sun is three hundred thousand times heavier than the Earth and more than a million times larger.
