1 . China has taken a whole new step in its moon exploration. President Xi Jinping on Dec. 17, 2020 congratulated the complete success of the Chang’e-5 mission(任务) that brings back the country’s first samples collected from the moon. Following America and Russia, China has become the third country in the world to collect rocks from the moon.
Chang’e-5 first took off from the Wenchang Spacecraft Launch Site in Hainan on November 24, 2020. It landed on a massive lava plain (熔岩平原) of the moon on December 1, 2020. Then it started to collect the samples. The samples may help scientists understand more about the moon’s origins. It may help work out how the moon comes into being and how it develops. Hopefully, the success of the collection will set an example for other more difficult missions in the future which will be carried out on other planets.
After the returning capsule (太空舱) landed back on Earth, it will be taken to Beijing by plane, where the capsule will be opened and the samples will be ready for study. “China will also provide some of the samples to scientists in other countries”, said Pei Zhaoyu, a director at the CNSA.
As the Chang’e-5 mission has been completed successfully, Chinese scientists are already making plans for future moon exploration, including project to build a scientific research station on the moon. “We hope to work together with other countries to build the international lunar scientific research station, which could provide a shared platform for lunar scientific exploration and technological experiments,” Pei said.

2 . If you watch the sky for about an hour after the sun goes down, you may see some “moving stars”. But they’re not really stars. They’re man-made satellites. And the biggest of all is the International Space Station（ISS）. From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes.
The ISS is the biggest satellite（人造卫星）and scientists want to live on it. They think that the best way to learn more about space is to live there.
When the space station is finished, it will be like a city in space. People will stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most expensive space program. Billions of dollars are being spent on it every year.
Scientists hope that the ISS will be a stepping stone for future space exploration（探测）. “The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better,” said Kathryn Clark, an ISS scientist.
Sixteen countries are part of the program: the US, Russia, Canada, Japan, Brazil and 11 European countries. China isn’t an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice up to the ISS to find out what space would do to it.
1. The International Space Station _____________.| A．is really a big city in space | B．is the biggest man-made satellite |
| C．can only help us explore space | D．is mainly built by the USA and Russia |
| A．building the ISS is only for scientists to live there |
| B．scientists can do anything they like there |
| C．people can see the Space Station at any time |
| D．sixteen countries are members of the space program |
| A．滑梯 | B．巅峰 | C．垫脚石 | D．走廊 |
| A．be used as astronauts’ food | B．sell it to aliens |
| C．do some science experiments | D．make it grow better in space |
| A．China will join the ISS in the future. |
| B．The scientists are building living rooms for them in the ISS. |
| C．The ISS will be more useful in the future. |
| D．The ISS costs the members of 16 countries plenty of money every year. |
3 . Shlander is a man from space. He thinks the people and things on the earth are very strange. He is now writing a letter to his friend at home. Here is part of his letter. Read it and answer the questions.
Now I am in a strange world. It is very nice. There are many new things here. There are many earth monsters here, too. The earth monsters look very funny. They have just one head, two arms and two legs. They have thin black strings on their heads. Some earth monsters have brown or yellow strings. The earth monsters have a hole in their face. Every day, they put nice things and balls from the trees into the hole. They put water into the hole, too. The earth monsters do not walk very fast. They move from place to place in tin boxes.
At night, the earth monsters like to look at a square window box. This box has very small earth monsters in it.
1. Shlander thinks the people and things on the earth are very ________.| A．strange | B．nice | C．different | D．beautiful |

4 . Many people don’t know that junk has become a problem in outer space. According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And some of
A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth a comet goes around the sun, but on a much longer path than the earth travels.
If a comet isn’t a star, what is it then?
Some scientists think that a large part of a comet is water frozen (冻) into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.
Many people have seen a comet. However, no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.
An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley comet, because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s comet when it comes near the earth again.

Years ago, they knew many facts about the moon. They knew how big it was and how far away it was from the earth. But they wanted to know more about it .They thought and thought. At last they found the only way to know more was to send men to the moon.
The moon is about three hundred and eighty-four thousand kilometers away from the earth. A plane can not fly to the moon because the air reaches only 240 kilometers. Then there is no air. But something can fly even when there is no air. That is a rocket.
How does a rocket fly? There is gas in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky.
Rockets can fly far out into space. Rockets with men in them have already reached the moon. Some rockets without men in them have flown to other planets much farther away than the moon. One day rockets may be able to go to any place.
