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 Chang’e 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. 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 180 kilometers 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.

When French musical Mozart-L’opera Rock toured nine Chinese cities in the last two years, it drew a big crowd of fans, including Chen Yike, a 28-year-old resident of Hangzhou.
“It was the first French musical that I had ever seen,” Chen said. She was so captivated by the show that she saw the production two more times.
Chen is one of many young Chinese who are increasingly fueling the country’s performing arts market. More and more young people are investing time and money in live performances, such as concerts and plays.
According to a report released by the Lighthouse Research Institute and ticketing firm Damai on March 25, young Chinese accounted for a record 55 percent of consumers of performing arts ticket sales in 2019 and 72 percent of concert attendees were people born after 1990.
Xiaomi, a 25-year-old girl from Chongqing became a loyal fan of singer Hua Chenyu after she saw his concert at the National Stadium in Beijing in 2018. Last year, she and three of her friends even traveled to Hainan province to see one of his concerts.
“It has now become a way of life for young people to spend money on performances by their idols,” Zhang Yiwu, a professor at Peking University, told China Daily.
Apart from young audiences, Chinese young performers are also doing increasingly well in the domestic (国内的) market and show a great potential for indigenous (本土的) culture to build a stronghold (大本营).
For example, the 19-year-old Chinese singer-actor Jackson Yee (易烊千玺) featured as a coach on the reality show Street Dance of China (《这！就是街舞》). With more than 80 million followers on his Sina Weibo platform, Yee’s participation helped attract audiences to an otherwise less known art.
On the iQiYi’s The Big Band, many young bands got the opportunity to show their music, and some have become quite popular. As a result, music that would have remained underground is now in the spotlight. “Many young bands on the The Big Band inspire me to learn more about their stories and indie (独立制作的) music,” Yang Zixu, a fan of The Big Band, wrote on the Chinese Q&A platform Zhihu.
Thanks to the joint effort of young audiences and performers, there’s “a driving force for Chinese cultural and creative industries” and it also “indicates China has entered a higher stage of development with better economic and social foundations,” according to China Daily.

We all want to be successful in our work. But what happens when our achievements come at the risk of losing important friendships? If your friends didn't receive what they were hoping for, your success could make them feel like they've been “left in the dust”. But does that mean that we shouldn't enjoy our achievements in case we displease someone or that we should feel sorry for being successful when others aren't?
Those of us who value friendships and close working relationships might feel embarrassed for achieving more than our friends. But we deserve our success, and nothing should take it away. Jealousy is only natural, but It’s often unreasonable, too. Your success is probably not connected with your friends' progress, so you shouldn't feel bad about achieving your goals. If your friends stay unfriendly, don’t be afraid to keep yourself away from them. You are not responsible for their weaknesses, and nor should they treat you sharply for furthering your work.
On the other hand, your friends may think highly of your recent success while hiding their real feelings. They could be jealous, angry or sad that they are not progressing at the same rate. So, be careful not to boast. It's a thin line between pride and self-importance, and by crossing the line, you may risk losing team support.
Next time you want to boast about your end-of-year win, or high-class new office, consider your listeners. Maybe your friends narrowly missed out on a position-raising, or experienced pay cuts which meant they didn't get what they were expecting. If your work is on a rising path, it doesn't mean that's the case for everyone.
Perhaps a step forward in your work has meant that you don't spend as much time with your friends as you used to. If you've changed a post or moved to a new office, take the time to stay in touch with old friends. Chances are that in the build-up to your success you've built strong relationships along the way. Don't let that hard work go to waste by losing touch with them.
1.From the first two paragraphs, it can be inferred that ________.
A.we should enjoy our deserving success

2.Which of the following best explains “boast” underlined in Paragraph 3?
A.Show up. B.Stand out.
C.Talk big. D.Keep silent.
3.What should we do if our friends support our success?
A.Improve ourselves further.
B.Consider their feelings.
C.Help them make progress.
D.Make them proud of us.
4.What does the text mainly talk about?
A.How to share our success with friends.
B.How to enjoy our success to the fullest.
C.How to keep relationships between friends.
