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 its tides(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.

There is no doubt that a mother plays an important leading role in the lives of their children. But what about a ①   ① ? Fathers play just as important a role as mothers.

Fathers give us support. They are the shore（岸）we swim to when our arms and legs feel tired. ②They are the strength we rely on （依靠）as we take our first steps into the world. Fathers can be gentle and powerful, but they probably have the simplest love we ever know.

For sons, the father is their first hero and possibly the only man they will ever feel comfortable loving.

For daughters, the father is the first man they admire and the first man whose eyes shine with happiness when they look at them. He is the first man to fall in love with them.

For mothers, the father of our children is the person we can believe in to watch over the babies as closely as we would. We are protectedin the knowledge of their love. A father is the person on the planet with whom we can do whatever we want ... one who will be just as interested and never feel bored in the face of our devotion.

Without fathers, we wouldn't be mums. I would like to thank them from all our hearts for this honor and for being our partners in the business of raising children.
