1 . Would you like to take a trip to the moon? People have already landed on the moon. Some day, the moon might become a popular place to visit. How will a trip to the moon be? Here are some facts.

There is no oxygen (氧气) or water on the moon. In order to stay alive (活着), you would have to take your own oxygen and water. It is silent (寂静地) on the moon. Sounds can’t be carried from place to place because there is no air. On the moon, the temperature goes down to 240℃ below (在……以下) 0℃ at night, and it warms up to 212℃ above 0℃ during the day.

What will the surface (表面) of the moon look like? The moon has more than 30,000 holes on it. One of the biggest is 146 miles wide.

When you walk on the moon, you’ll feel light on your feet. That’s because you weigh only about 20 pounds on the moon. You might forget what day it is there because a moon day lasts for two weeks. But you won’t need an umbrella anymore because it never rains on the moon. And the weather on the moon never changes at all.

2 . 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.

1. Who is in danger of radiation in space?

A．Scientists’ children.

B．People on the earth.

It’s very beautiful. But during spring and summer, the surface of Mars is covered by strong     5    . The gravity on the surface of Mars is about two     6     as strong as it is on earth. So a person who weighs 90 kilos on earth weighs only 36 kilos on Mars. The temperature on Mars is     7     -138°C and 28°C. The air has only 0.13% oxygen.

It     8     a spaceship about eight months to reach Mars from the earth when the two planets are the     9     to each other. Scientists are still     10     for more information about Mars.

8 . It’s 2050. The Earth is dying, and moving to Mars seems to the only way out for humans. A team of American astronauts (宇航员) begin to search on Mars. This is what the movie Red Planet begins with. Known as the Red Planet, Mars is the favourite of writers and filmmakers.

Mars is the fourth planet from the Sun and the next planet beyond the Earth. Mars is the only planet whose surface can be seen from the Earth. It is about half size of our planet.

The surface of Mars is more like the Earth than any other planet. But it is further from the Sun than the Earth, so temperatures on Mars are much lower. Plants and animals can not live now on Mars. But many scientists still believe that such life may have been on Mars long ago.

On 6th August, 1996, scientists discovered a piece of rock from Mars, which fell to the Earth 13,000 years ago. 10 years later, some scientists still didn’t accept that there was life on Mars. People may not be sure about life on Mars until a sample (样本) of life is brought back. Some further researches are being done in many countries.

9 . Dangerous junk

On Nov 16, seven astronauts on the International Space Station (ISS) woke up to an alarm. A Russian missile (导弹) test had just blasted (炸毁) a satellite (卫星) into more than 1,500 pieces of space debris (残骸) . Some got very close to the ISS.

NASA says space debris like this can travel at more than 28,000 km/h. That’s much faster than a bullet (子弹) (about 3,500 km/h). Even a pea-sized piece of debris could “wipe out” a space station or kill an astronaut if he or she is doing a spacewalk, says Live Science.

Since the 1950s, humans have sent thousands of rockets and satellites into space. Many are still there, and we now face an ever-increasing risk of space junk.

In 2006, for example, National Geographic reported that a tiny piece of space junk hit the ISS, taking a chip (一小块) out of a window. In June of this year, a piece of debris ran into one of the station’s robotic arms and left a hole.

Scientists are trying different ways to deal with the problem. One way is to use a huge net.

In 2018, the UK’s Surrey Space Center caught some space junk with a net in an experiment. It first found the debris, and then collected it with a net and a harpoon (鱼叉) .

Another solution is to use robotic arms. ClearSpace 1, the European Space Agency’s mission (任务) to clean space junk, is going to be sent into space in 2025. It will use robotic arms to catch debris. The mission plans to throw the debris into Earth’s atmosphere (大气层) , where it will burn up as it falls because of intense friction (摩擦) .
