1 . ① Man has known more and more about space today. Space is not only wonderful but also dangerous. While working in space, astronauts are facing danger.
② Scientists have found out that radiation (辐射) is the greatest danger to astronauts in space. When astronauts are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage of radiation is difficult to discover until their children or even grandchildren are born. Some special medicine may work a little, but there isn’t really helpful medicine.
③ Space rubbish is also a great danger to astronauts. There are 9000 man-made (人造) things flying in space. About 30% of these are man-made satellites (卫星), 10% are spaceships, and others are space rubbish. Even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and telling any possible danger all the time. They are working on helpful ways to do with space rubbish.
④ Although space is really dangerous, everyone on the earth is interested in it. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space for a few years. So we should care for space and do something to help improve the space environment.

2 . The Moon is attracting much attention these days as NASA is ready to send space rockets there and preparing for more to follow. The mission’s objectives are clear: to create a long-lasting base on its surface and prepare to go to Mars one day.
What’s the next great move in humans’ quest for the secrets of the universe? When it comes to the near future scientific research in space, there are a few areas in the solar system that will receive some special attention.
First of all, there’s Venus, a planet which was like a paradise to human with oceans and a pleasant atmosphere. However, something went terribly wrong there a few billion years ago, and NASA has scheduled a series of missions to explore what exactly is going on there.
At the other end of the solar system are the gas planets. Several of the satellites of Jupiter and Saturn are covered in thick sheets of ice, and underneath the ice are oceans of liquid water. NASA has missions planned to investigate those mysterious worlds, hunting for any sign of possible life hidden deep within.
As for us humans, Mars is certainly the grand prize in the coming decades. If we have enough money for the trips, we can perhaps keep astronauts working and studying on the surface of Mars for quite a long time. The other planets in our solar system are not so suitable for people to settle on. For example, Mercury is too close to the Sun and too far away from the Earth.
In the coming decades, humans expect to see a rise of “space hotels” set up for visiting tourists and scientific explorations. Because of our current level of technology, it is not very practical to turn the space rock into a place suitable for humans. But it may be the next easiest thing to achieve after going to the Moon and Mars.

3 . The 2022 Winter Olympics were held successfully. Athletes (运动员) across the world came to Beijing and Zhangjiakou. Winter sports need to be in cold places. So, is it possible to hold the Winter Olympics on other planets?
| Mercury (水星) It’s the closest planet to the sun. In the daytime, the temperature can be 430℃. At night it cools down to -200℃. There’s one area that the sun can never reach. There’s lots of ice there. Maybe we could go speed skating there! |
| Mars The temperature on Mars is between -140℃ and 30℃. At the north and south poles of Mars, there are areas covered by ice and snow. Some of the ice is made of carbon dioxide (二氧化碳), not water. There is also a big mountain called Mount Olympus. So maybe we can ski on Mars! |
| Pluto (冥王星) Pluto is a small dwarf planet (矮行星) far away from the sun. It’s very cold there, about -229℃. There’s lots of ice. It’s even harder than steel (铁). So maybe we could go sledding (滑雪橇) on Pluto. |

4 . In the universe, as we know, there is the sun, the moon, the earth and many stars. Through our geography lessons, we know the earth goes around the sun, and the moon goes around the earth. We have day and night because the earth keeps turning all the time. When our part of the earth turns to the sun, it is day. When our part of the earth turns away from the sun, it is night.
Just because the moon is closer to the earth than the sun, it looks much bigger than the sun. Big things look smaller when they are farther, and small things also look bigger when they are nearer.
The sun is bright enough to give out very strong light. The moon can’t give out any light at all, but it looks quite bright too. Why? In fact, the light from the moon comes from the sun. The moon looks much bigger and brighter than the stars. But actually the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are farther away from the earth.
There are still many other planets in the solar system (太阳系). All of them move round the sun. But of all these planets, only on the earth there are living things and people can only live on the earth too. At 9:00 am on October 15th, 2003, Chinese pilot Yang Liwei was sent up to space. He stayed there for 21 hours. It was the first time for Chinese to get into space.

Humans have always been interested in the moon. About 2, 000 years ago, scientists had already known that the moon moves around the earth and where it would be in the sky at different times of the year. In old times, everything about the moon was learned by watching it carefully at night.
When scientists could use telescopes (望远镜) to study the moon more closely, they found the moon was made of rocks. Most scientists thought moon rocks would be different from those on earth. This was because they believed the moon had once been a planet that was caught in the earth’s gravity millions of years ago.
In 1969, moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again, new ideas were needed for this new study.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 million years ago, something that was about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
Humans’ steps of exploring the moon will never stop. In the future, even though our ideas about the moon may change again, we’ll still show an interest in it.
1. At first, most scientists thought moon rocks were2.

4. People will never stop
5. How did people learn about the moon in ancient times?
9 . ①On a clear night, go outside and look for the moon. Do the same thing again a week later, and the moon you see will look different. So why does it always seem to change its shape?
②Sometimes, the moon is a bright disk that lights up the night sky. Other times, it is just a white sliver. Sometimes, the moon can be seen during the day. Other times, it can not be seen. These different kinds of visibility (可见度) are called the phases of the moon (月相).
③They appear because the sun, the moon and the Earth are always moving. One thing that almost never changes is that the sun lights one side of the moon.
④A lunar eclipse (月食) is the only time the sun can’t face the moon. This appears when the sun, the moon and the Earth are in a straight line with the Earth in the middle. As the moon travels into the darkness of the Earth’s shadow (影子), it seems as though all or part of it disappears.
⑤Many scientists believe that the moon was once part of the Earth. Millions of years ago, something hit into the Earth and broke off a large part of the planet. Gravity (地球引力) kept this huge block from going away into space, and it became our moon.
