5 . Do you know something about the moon? You can see it at n    1    . Sometimes it looks round and bright. It also looks quite near. B    2     the moon is very f    3     from the earth. If you take a spaceship, you will get there in more than three days. The spaceship goes very fast, at 11 kilometers a second. In 1969 two Americans got on the moon by spaceship.

There are no living things on the moon b    4     there is no air or water there. That's why people can't l    5     there. But you may know you can jump much higher there than on the earth. It's fun, isn't it?

7 . Hey! The people of the earth. Can you hear this radio message? Do not be afraid! We come in peace from another planet— and why not? We are your cousins. We are men, as you are. We have been here before.

You will see a huge spaceship, a few hours from now. We are flying towards the solar system (太阳系) almost as fast as this radio message. Your sun is already in sight. Our ancestors (祖先) and yours shared the sun ten million years ago. I’m sure you have forgotten your history while we have remembered ours.

Our ancestors lived on the Earth when dinosaurs were dying. Sadly, they could hardly save the beasts. Your planet was very warm then. Our ancestors believed it would make a nice home for them.

They were wrong. Though we were masters of space, we knew so little about the Earth.

For millions of summers — there were no winters in those ancient days — the Earth had rapid (飞速的) development. It took about thirty years to fly from one planet to another, so our ancestors seldom travelled in space. But they never felt lonely. They kept in touch with their relatives and friends on other planets. Three or four times every century, starships would call and bring them space news.

But two million years ago, the Earth began to change. The temperatures fell quickly. The ground was covered with snow and ice. At that time, however, our ancestors knew little about that. Those who had called the Earth their home believed there was just a strange disease spreading on the earth. The disease wouldn’t cause death to them, but it would bring much pain and do harm to men’s health.

1. How soon will the people on the earth see a huge spaceship?

2. Why did the speaker’s ancestors seldom travel in space?

8 . Humans have always wondered about the Earth they live on and about the sky above them.

When early humans looked at the night sky, they _____ themselves a lot of questions. They looked at the Moon and _____ what this strange bright object in the sky was.

They also thought about the _____ of the Earth. All the early people believed the Earth was flat.

In the sixth century BC Pythagoras put forward the _____ that the Earth was round. ______, he could not explain why people at the bottom of the Earth did not ______.

It was not until the sixteenth and seventeenth centuries that scientists found the answers ______ some important questions. Galileo’s telescope made ______ possible for people to see the sky more ______ and find the positions of the stars and planets. Finally in 1665, Isaac Newton ______ to the world what gravity was and people understood why they did not fall off the Earth.

The planet Mars is the closest and most similar planet to Earth. It is very    1    to scientists. For example, Mars has seasons with    2    weather, but other planets have the same temperatures all year round. Was there    3    on Mars?

To find out, scientists need    4    if Mars ever had water. In 2004. two robot explores (探测器), or 'rovers', called Spirit and Opportunity were sent to look for    5    of water. These rovers can drive over rocks    6    all kind of rough ground. They can also use cameras and send photos    7     to Earth. First, the two rovers found chemicals and patterns (图文) in the rocks that were probably made by water. Then, they moved to another area and    8    other rocks which may have been created by water. Now scientists think there was probably water on the planet long ago. Today       9    are still not sure if there was life on Mars. They    10    need more information to decide. The discoveries of the two rovers answered some old questions, but they also brought up many new ones.

10 . As space science develops, man has learned more and more about space. Space is not only a    1     but also dangerous. While working in space, spacemen are facing danger as well as s    2    .

Scientists have found out that the in radiation(辐射)is the greatest danger to spacemen. When spacemen are working in space, they are in d    3     of the radiation from the sun and other stars, which is bad for their health. The h    4     of the radiation won’t be found until their children even grandchildren are born. Some s    5     medicine may work a little, but no really effective medicine has been found so far.

Space r    6     is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are s    7    , and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments (碎片), each at least 4mm in size. A small piece of these even knocked a spaceship window and c    8     some damage（损 坏）.

Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. A    9     space is really dangerous, it interests many people on the Earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help i    10     the space environment.
