The moon may shine white above us most nights...

The moon may shine white above us most nights of the year, but how much do we know about Earth’s neighbor and what lies beneath its surface? Scientists are aiming to find out.

On Jan 3, 2019, China’s Change 4 spacecraft landed on the far side of the moon a first for humanity. It released a small probe（探测器）,Yutu 2, or Jade Rabbit 2, which began to search beneath the moon’s surface using Lunar Penetrating Radar（探测雷达）. These radio signals can reach 40 meters underground, three times the depth of the Chang’e 3 lunar probe launched in 2013 for the near side of the moon, China Daily reported.

In a study published in the journal Science Advances, researchers found that the lunar soil’s top layer on the far side of the moon was much thicker than expected ﹣ about 40 meters. Other scientists only expected about 6 millimeters of soil based on NASA observations during the Apollo moon landings, according to The New York Times.

“It’s a fine, dusty, sandy environment, said one of the authors of the study, Elena Pettinelli, a physics and mathematics professor at Rome Tre University, Rome.

Yutu 2 is specifically exploring the Von Karman crater（大坑）,a large hole that’s 180kilometers wide and also the landing site of Chang’e 4. It’s part of an even larger, older crater spanning more than 1,770 kilometers.

“The subsurface at the Chang’e 4 landing site is very complex,” said Li Chunlai, a research professor and deputy director﹣general of National Astronomical Observatories of the Chinese Academy of Sciences. Observations suggest that the subsurface material is totally different than the previous landing site of Chang’e 3, she said.

Radar waves revealed various layers beneath the moon’s surface: grainy（ 颗粒状的）material, boulders（岩石）,and further layers of fine and coarse（粗糙的）particles. This information is helping scientists to gain new understanding of the moon’s history and formation, as well as volcanic activity and lunar impacts.

Yutu 2 is the longest﹣working rover（巡视器）on the moon, but it won’t last forever. China plans to launch the Chang’e 5 probe later this year, Xinhua News Agency reported. The spacecraft is expected to bring pieces of the moon back to Earth for closer study.

Who Owns the Moon?

Within the next ten years, the US, China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does that give them property rights?

A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international law signed by more than 100 countries, states that the moon and other celestial bodies(天体) are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs.

But ownership is different from property rights. People who rent apartments, for example, don’t own where they live, but they still hold rights. So with all of the upcoming missions(派遣团) to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush.

“This is a very relevant discussion right now. We’ve got this wave of new lunar missions from around the world,” said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA’s Co Lab, a collaborative(协力的) public-private working group. He was peaking from his personal interest and not on behalf of the agency.

To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission.

1.In the passage the writer seems to be worrying that 　　　　 .

A. the US will live on the moon forever

B. the moon will not be able to hold all mankind

C. the potential land rush will become more and more frequent

D. no one can answer the question “Who owns the moon?”

2.The “Google Lunar X Prize” aims to 　　　　 .

A. encourage private groups to land on the moon

B. help NASA host a discussion about land rush on the moon

C. help some developing countries complete their lunar projects

D. reward some countries or private groups which haven’t stepped on the moon

3.The underlined word “that” in the first paragraph refers to 　　　　 .

A. the Outer Space Treaty　　　　　　 B. if and when they plant a flag

C. the NASA working group　　　　　　 D. monks from the Middle Ages

4.What is the main idea of the last paragraph?

A. The US astronauts will live on the moon for a longer time.

B. Many countries and private groups plan to go to the moon.

C. Why some private groups wish to land on the moon.

D. It is easy to gain some property rights on the moon.

Most of us have looked up at the stars that fill the night sky and wondered whether we’re alone in the universe. Indeed, the question of whether there’ s life out there has been something humankind ’s been asking itself for countless years. But thanks to China’s Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

The telescope has a huge round reflector, which measures 500 meters across and has a perimeter（周长）of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST’s designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. “Panels can change their positions through connected wires and parallel （关联的） robots. We can control their position with an accuracy of 1 mm,” Zheng Yuanpeng, chief engineer of the telescope’s panel project, told Xinhua News Agency.

FAST’s engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. “There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST’ s construction, told Xinhua.

And although it wasn’t yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars （脉冲星） have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.

1.What is the purpose of mentioning the question in Paragraph 1?

A.To introduce the new giant telescope.

B.To explain why there is life in universe.

C.To remind readers to think about the life in space.

D.To emphasize the question that should be answered.

2.What can we know from Paragraph 2?

A.The telescope is made up of many panels.

B.The area of FAST is about 800 square kilometers.

C.The engineer can handle FAST’s position accurately.

D.The individual panel helps scientists catch radio signals.

3.Why was FAST built in Guizhou?

A.Because Guizhou is a remote province.

B.Because Guizhou has an ideal valley.

C.Because Guizhou has beautiful mountains.

D.Because Guizhou has the ability to build it.

4.What does the last paragraph mainly talk about?

A.FAST’s timeline. B.FAST’s future.

C.FAST’s operation. D.FAST’s discoveries.
