1 . I rise in the east, and it is day. I send my light into your room, and tell you it is time to get up. When I shine, you can not lie in bed or sleep. You must work and study.
I send my light here and there. I shine over the trees, the houses, the hills and the water, and I make everything beautiful.
I am high up in the sky, higher than the highest mountains, higher than the clouds. Sometimes I hide(藏)my face behind a thick cloud, and you cannot see me. But when there are no clouds and the sky is blue, and when I shine at noon, you can not look at me, because I am too bright.
When I am going to rise in the morning and begin the day, the birds fly into the sky to meet me, and cocks crow to tell everybody that I am coming.
It seems that I am a great traveler in the sky. I never stop, and I’m never tired. But, in fact, it is the earth that is traveling around me all the time.

A team of scientists are carrying out a project at the University of Greenwich in London. They are trying to find ways to make food on Mars in the future. The project is called Feeding Mars. It tries to use water, fish and fish waste to grow fruit and vegetables on Mars.
It would take at least 21 months to reach Mars, learn about its surface and return to Earth. So it would be a big help if the spacemen could grow fresh food on Mars itself. However, farming on Mars will be very hard. There’s a lot of water that could be taken from ice just below the surface, but the land on Mars is short of the nutrients that living things need. The team says that they could solve the problem by growing plants and fish together. Fish waste can then be used to provide nutrients for plants.
“It is expected that you can grow lots of food, such as vegetables, tea and medicinal plants on Mars,” said Dr. Benz Kotzen, who leads the project. “You can even harvest fish for food then.”
1. The project tries to use water and fish to grow fruit on the moon.2. The project would take at least 21 months to return to Mars.
3. The poor land condition makes it difficult to farm on Mars.
4. Scientists could grow plants and fish together to solve the nutrients’ problem.
5. Dr. Benz Kotzen was disappointed about this project.
5 . The question whether there is life on Mars (火星) has made the public think a lot for more than a century. A British spaceship and Europe’s Mars spaceship plan to land on Mars or enter the orbit (轨道) around it. One of the NASA’s (美国国家航空和航天局的) spaceships is expected to land on January 3, and the other is going to land on the opposite side of Mars on January 24.
Since 1960, over twenty spaceships sent to Mars have failed. Most were lost when they started flying up or landing because those were the most difficult time of any flights.
Scientists wanted to find out whether there was water on Mars. In October, a team of scientists reported that Mars was a dry wasteland (荒地). But weeks later, a second team reported differently that they had found some marks (痕迹) which showed clearly that they were made by the rivers. Such marks told us that Mars was a warmer place billions of years ago — just as life first appeared on Earth. Scientists at once asked the following questions: If what they said was true, what happened on Mars? Then what about the earth?
1. The question ________ has made the public think a lot for more than a century.| A．when Mars came into being | B．how people can fly to Mars |

| A．Life disappeared on Mars. | B．Spaceships couldn’t land on Mars. |
| C．The air on the earth got less and less. | D．The earth might be changed like Mars. |
6 . As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that the radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health.
The harm of the radiation won’t be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.
Space rubbish 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 spaceships, and the rest are space rubbish. An explosion (爆炸) in space in 1999 made a cloud of 300, 000 fragment (碎片), each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage (损坏).
Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth.
We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.
1. The radiation from the sun and other stars is ________.| A．good | B．helpful | C．useful | D．harmful |
| A．spacemen working in space | B．people only on the earth |

| A．Space Radiation | B．Space Danger | C．Space Junk | D．Space Travel |
7 . There are many stories and poems about the Moon in Chinese history. And now scientists send spaceships to the Moon. Why? Because people are always interested in the Moon and want to know more about it. Here is some information(信息) about it. Let’s see it together.
The Moon looks beautiful and bright at night. It is far away from the Earth and if you want to get to the Moon, it will take you about 6 months to get there by car at 95 km per hour.
There is no gravity on the Moon, so people can enjoy floating there. If you weigh 68 kg on Earth, you will weigh only 11 kg on the Moon.
There are many interesting places such as craters(陨石坑), mountains and lava plains(熔岩平原) on the Moon. There is no air on the Moon, so people can’t breathe on it.
On Earth, the day is usually warm and the night is cool. And there are four different seasons in a year. But on the Moon, the temperature is very high during the day and very low at night. And a full day on the Moon, from the sunrise to the next, lasts about 29.5 Earth days on average(平均).
The Moon doesn’t have its own light. It looks bright because it can reflect(反射) light from the Sun. When the Moon moves around the Earth, it gets different light from the Sun. So we find its size often changes.
1. Why are there many stories and poems about the Moon according to the text?| A．Because people in the past wanted to live on it. |
| B．Because people like it and want to know about it. |
| C．Because people in the past couldn’t understand it. |
| D．Because it is a symbol(象征) of beauty and love. |
| A．Less than 5 kg. |
| B．More than 10 kg. |
| C．Only 7 kg. |
| D．About 9 kg. |
| A．People can lose weight on the Moon and breathe in fresh air there. |
| B．People can float to the Moon now and enjoy themselves over there. |
| C．Two days on the Moon equal(等于) about fifty-nine days on Earth. |
| D．The day is very hot and the night is cool in the summer of the Moon. |
| A．To tell us some ways of travelling to the Moon. |
| B．To tell us some important facts about the Moon. |
| C．To tell us some interesting stories about the Moon. |
| D．To tell us the differences between the Earth and the Moon. |

9 . There is a new sight in the sky these days —the newly-discovered Comet (彗星) NEOWISE is flying past the sun. This the first time since the 1990s when people have had a chance to see a comet with their bare eyes (裸眼).
A comet is basically a ball of dirty ice that moves around the sun. As a comet comes close to the sum, the sun melts some of the ice, which makes a tail behind the comet as it flies through space. Most comets move around the sun in a circle. Comets spend most of their time moving slowly, far away from the sun. As they pass the sun, they speed up.
The size and shape of a comets moving way can influence how long it takes to finish its one circle. Halley’s Comet is a famous comet coming around once every 75-76 years. But the last time Comet NEOWISE was here near the sun was about 6, 800 years ago. Because of the long time it takes to finish its one circle, NEO WISE was only just discovered some months ago. It was seen in March with a special space telescope run by NASA.
The name of the telescope system that first saw the comet is NEOWISE, so that’s how the comet got its name. NEOWISE is easy to see now because it is close to the sun. At its farthest, NEO WISE will be 630 times farther away from the sun than the earth is.
Even at its closest—which was on July 23 —the comet was still as far away from the earth as Mars was. But it was still bright enough to see, even without a telescope.

10 . Mars (火星) is a planet (行星). It is the fourth planet from the sun and is more than 200,000,000 kilometers from it. That is a very long way. Mars is also a very long way away from Earth but sometimes you can see it clearly at night. Most stars are white. But Mars is a little red. It is a very big planet. It is about half the size of Earth. The planet Earth has one moon. Mars has two moons. They are called Phobos and Deimos.
Long ago, the only way to study Mars was just to look at it. People with good eyes could see some things but not everything. Later on, it was easier, because scientists had telescopes (望远镜). They could see Mars come clearly. They learnt much more about Mars this way. In the twentieth century (世纪) things got even better. First of all, we had spacecraft. They flew close to Mars and sent back information. Then, they sent spacecraft to fly around Mars. Finally, spacecraft landed (着陆) on Mars.
Maybe one day a man will walk on Mars.
