Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.
And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.
We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised itstides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.
These small pieces have been going round the sun ever since. They are the planets.

Every day when Cora Castle, 14, from Indiana, US goes back home, she opens her computer and logs into a website（登录网站）called Fuel Up to Play 60.

    She puts on what she has eaten and what kind of activities she has played that day. Then the site decides whether Castle has eaten healthily and done enough exercise.

    All the seventh graders in Castle's school have done the same thing since the year started. It's part of their health class.

    If the site finds her habits are unhealthy, it will give her advice. If she does something good, the website will give her a star.

    Her health teacher set up a competition to see which student could get the most stars from the website. Castle has got 30 stars so far.

    Cameron Bartlett said she liked tracking（跟踪）the food and activities. "This is the first year we've done it," she said. "It's really interesting to see all of the different choices that we have."

The seventh grade health class is coming to an end. They won't be in health class, but the students all said that they would go on to take part in the Fuel Up to Play 60.

    "There's lots of bad food out there that we've all been eating," Bartlett said "This really helps all of us eat healthier food."
