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.
【小题1】Most stars are _________________________.

A.following a regular path in space

A.the star moved away from the sun

Throughout history, people have been interested in knowing how language first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the language of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original language of this family was spoken about 4,500 years ago. Many of the present-day languages of Europe and India are modern forms of the language of 4,500 years ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. In time, some even die out completely. About 1,000 years ago, English was a little known relative of German spoken on one of the borders of Europe.
If a language has a number of speakers, or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of people. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can’t understand speakers from other parts.

C.A language has many speakers, but there may be no differences in the way it is spoken in different areas.
