As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.
Let’s think about how this works. As wave energy passes through the water, the energy makes particles (粒子) of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.
   So why can you see a wave knock you down on the shore?When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.

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
B.moving about without a fixed course
C.seldom wandering about in the universe
D.always travelling together
【小题2】Some two thousand years ago, the mountain on the sun was raised probably because _____________.
A.the star moved away from the sun
B.another star happened to come near the sun
C.the sun and the moon raised the tides on the earth
D.a large tidal of wave travelled over the surface of the sun
【小题3】The article suggests that _______________.
A.how space formed
B.our earth exists before the sun
C.no one knows where the earth comes from
D.our earth used to be a high mountain in the sun
【小题4】The expression “the cause of the disturbance” refers to ________.
A.the large tidal waveB.the powerful tidal pull
C.the star coming near the sunD.one of sun’s planets
【小题5】 In the article, the writer mainly wants to tell us ______________.
A.where the planets in the universe came from
B.how the high mountains were formed on the sun
C.that the universe is so large that we cannot imagine it
D.why the tides over the surface of the sun were so powerful

We are all busy talking about and using the Internet, but how many of us know the history of the Internet? Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time, At first the Internet was only used by the government, but in the early 1970s. universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" the Internet easier. Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among young people. The Internet has now become one of the most important parts of people's life.

1.How long has the Internet been used?

A. For over 10 years.                        B. For over 20 years.

C. For over 40 years.                        D. For over 60 years.

2.What would happen when one computer in the network broke down after the new network system was set up?

A. The other computers would wait.

B. The other computers would still work.

C. Some of the others still worked.

D. The other computers wouldn't work.

3.Which of the following used the Internet first?

A. Hospitals    B. Universities       C. Banks         D. The government

4.What is true about computers in the 1990s?

A. They became cheaper and easier to use.

B. They became larger and larger.

C. People couldn't buy them anywhere.

D. People could get information only from them.

5.What can we infer from the last sentence?

A. People will die without the Internet.

B. All people should set up their own network.

C. People live easily without the Internet.

D. People will more and more depend on the Internet.
