In almost every big university in the USA, football is a favorite sport. American football is not like soccer. Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the other end of the field. They have four chances to move the ball ten yards. They can carry it or throw it, If they move it to the end of the filed, they receive six points. This is called a touch down.

It is hard to move the ball. Eleven men in the team try to stop the man who has the ball. If the man does not move the ball ten yards, his team kicks the ball to the other team.

Each university wants its team to win. Thousands of people come to watch. They all yell for their favorite team. Young men and women called cheerleaders come on the field to help the people yell more. They dance and jump while they yell.

Each team plays ten or eleven games each season. The season begins in September and ends in November. If a team is very good, it may play another game after the season ends. The best teams play again on January 1, the first day of the New Year. Many people go to see these games and many others watch them on TV.

If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).

A comet sometimes looks like a star.Like a planet, a comet has no light of its own.It shines from the sunlight it reflects (反射).Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.

If a comet isn’t a star, what is it then?

Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock.When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it.These clouds, together with the dust, form a long tail.

Many people perhaps have seen a comet.However no one knows how many comets there are.There may be millions of comets, but only a few come close enough for us to see.

An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky.Some comets move out of our sight and never come back.Others keep coming back at regular times.A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again.Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986.Then people all over the world were outside at night to look at it.You will probably be able to see Halley’s Comets when it comes near the earth again.
