2 . Chinese material scientists have found the soil on the moon may potentially be able to generate oxygen and fuel, a finding that means more possibilities of humans to use lunar resources to further exploration of the moon and beyond.
The researchers at Nanjing University showed that the lunar sample brought back by China’s Chang’e-5 contains active compounds (化合物) that can change carbon dioxide into oxygen and fuel. Initially, they hoped to design a system that took advantage of lunar soil and solar radiation, the two rich resources on the moon, according to a study published on Thursday in the journal Joule.
After analyzing the Chang’e-5’s lunar soil, the team found the sample contained metal-rich substances, which could work as a catalyst (催化剂) to make oxygen using sunlight and carbon dioxide. The team proposed a strategy using lunar soil to electrolyze water from the moon and the astronauts’ life support system into oxygen and hydrogen. The process was powered by sunlight. The carbon dioxide breathed out by moon inhabitants can be collected and combined with hydrogen to produce the fuel, also catalyzed by the lunar soil, according to the study. The researchers said with this method, no external energy apart from sunlight would be used to produce oxygen and fuel to support life on a moon base.
“We use the environmental resources to minimize rocket payload, and our strategy provides a scenario for a sustainable and affordable living environment for life out of the Earth,” said the paper’s first author Yao Yingfang from Nanjing University, expressing his assumption.
“The challenge lies in the fact that catalytic efficiency of lunar soil is lower than catalysts on the Earth,” said the researchers. They are testing different approaches in order to improve the design. The team is looking for an opportunity to test the system in space with China’s future manned lunar missions.

3 . In the past, music recording was primitive. A recording engineer placed microphones in front of instruments. The producer pressed record and signaled the band to play. There was a human touch to recordings, and this way of recording gave rock music its raw edge. But here we are today. Complex and advanced audio software sits in every recording studio. The higher cost and greater practicality make creating digital music common.
However, the modern recordings aren’t beneficial to a rock record. Let’s not forget, being in a band is laborious. You need like-minded musicians to rehearse for hours on end. Nowadays, this isn’t a necessity.
Programming drums on a computer is as simple as filling cells on a spreadsheet, and there you have it, a drumbeat. Only a few professionals are aware that they aren’t listening to true live drums. Such tech is even accessible on your smartphone. Whether on a train or in a bedroom, you can create a full band track without a live band.
What happened to rock music? With pop and hip hop dominating the charts, it feels like the time for bands is over. Is rock music really dying out? Is it really on its last legs, or are we just not trying hard enough?
Artists, inspired by the great rock bands, seek to put their own spin on this classic genre. The spirit of rock music still remains. One singer mixed soul and rock while one band combined indie rock with elements of techno, both with underlying rock characteristics.
The truth is that fresh rock bands are out there and you just need to dig deeper. A search through online music blogs shows a growing number of new rock bands. While rock bands are now not as popular as before and not receiving mainstream exposure, the flame still burns brightly.
1. Which words can best describe the past music recording?A.Underdeveloped and low-cost. | B.Easy and time-saving. |
C.Demanding and complex. | D.Digital and creative. |
A.Low demands for music. | B.Advanced audio software. |
C.Deep understanding of music. | D.Help from professional musicians. |
A.To tell rock music has lost its original attraction. |
B.To show rock music may be presented in new styles. |
C.To stress rock music is no longer mainstream music. |
D.To compare rock music with some other kinds of music. |
A.Is Rock Music Going Dead? | B.Why Is Rock Music Disappearing? |
C.A New Kind of Music Is Emerging | D.A Way of Recording Music Is Getting Accepted |

5 . How to Deal with Academic Failure
Experiencing failure in academic settings is inevitable in your journey to study. However, once you get through it, you can bounce back from almost any academic failure.
Adopt the proper mindset
The proper mentality plays a big part in dealing with academic failure.
Consider the troubles of chaotic personal relationships and stress. They are the most common external factor making students' academic performance suffer.
Bounce back
Once you have determined that, you need to develop a plan of action. Try to study at the same times and same places each day, so it becomes a routine. Enlist someone to help you stay accountable to your plan of action.
A.Identify the trouble spots |
B.Analyze extracurricular commitments |
C.Achieving academic goals is vitally important |
D.Instead of judging yourself for past shortcomings |
E.Only by recognizing your problems weren't created overnight |
F.Look at the history of your grades and determine the overall trend |
G.Talk to a friend, family member or teacher about helping you stay on track |

It was a Saturday morning as I prepared to take my eight-year-old son, David, to the aquarium. His eyes were widened with excitement, and he chattered non-stop about the sea creatures we would see, the sharks, the dolphins... We boarded the bus, and after a few stops, we made ourselves comfortably seated. David gazed out the window, watching the world go by with wonder.
The bus continued its route, and with each stop, it became increasingly crowded. Passengers of varying ages and backgrounds filled the seats. David and I were engaged in a light-hearted conversation about marine life, our anticipation and joy building with each passing minute.
As we approached a mid-route bus stop, an elderly lady boarded, her movements labored and her legs visibly unsteady. The bus was full, and for a moment, there was an obvious hesitation among the passengers, each perhaps weighing the social morals against their own comfort. The elderly lady seized her walking aid, swaying slightly with each lurch of the vehicle.
Noticing the elderly lady’s struggle, David made a decision. Without a moment’s hesitation, he rose from his seat. His small hand gestured towards the elderly lady. “You can sit here, ma'am,” he said, his voice clear and sincere. The elderly lady’s face transformed with a mixture of surprise and gratitude. “Oh, thank you, boy,” she said, her voice filling up with emotion. David then took her hand gently, helping her navigate through the crowd to the seat he had left for her. With the help of David, the lady eased herself into the seat, her relief evident. I felt pride welling up within me as I watched what David had done. Looking at David, who was standing now, I saw not just the playful child he was known to be, but the empathetic and considerate young man he was growing into.
