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.

6 . Arsh believes in the importance of making the world a more beautiful place. The talented boy not only paints but also sells his artwork and donates the money.
It all started when his parents bought him a set of painting tools for his 8th birthday. Once he had his own materials, he began spending much of his free time putting color on his canvas. As Arsh’s paintings began to grow in number, he decided to give them as gifts to friends and family. Receiving a positive response from people around him, he soon realized his pieces had the potential to get much more than smiles and praise.
His light-bulb moment came shortly after: he would sell his artwork and donate the money to charity. His first plan was to raise $1,000 for St. Jude Children’s Research Hospital, which he accomplished in around nine months by selling his paintings on social media and at local art shows. Since then, he’s broadened his reach to benefit other organizations, including childhood cancer nonprofit Compass to Care and the Make-A-Wish Foundation. He’s raised over $16,000 for charities so far.
Arsh’s artwork is often colorful and cheery, as one might expect from a youngster, but it showcases the impressive technique of a gifted artist. Some pieces are more abstract in nature; others feature realistic renditions (演绎) of flowers and animals. They range in size and complexity, and, accordingly, price. Small paintings might sell for $10 while larger canvases, up to five feet, have gone for $800.
Last year, Arsh won The Diana Award, an honor presented by a UK charity founded on Princess Diana’s belief that young people have the power to change their country. And the young artist has advice for other kids looking to make a difference. “Helping others doesn’t have to be, like, money or anything. It can be your time, your skills, your talent,” he says, “and overall, just be kind to other people to make their day better.”

8 . 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 |
“All suspects reportedly
The Beijing News reported that over the past months, this case of the 13-year-old boy, inhumanly killed by his three classmates,
The victim and his classmates are “left-behind children”,
The case has triggered an outpouring of grief on social media, with
On a cold winter day years ago, I slipped in the snow in the wilderness and broke my legs. As I lay on the ground, unable to move my body, I believed I was fated to freeze to death. My dog, Becky, however, didn't run away. Instead, she determined to save me. She lay on top of me to keep me warm for many hours, barking continually until help arrived, long after I lost consciousness. Eventually, I was saved.
A few cold winters later, Becky was discovered to have a baseball-sized lump (肿块) on her belly. Before long, my husband Bob took Becky for surgery to remove the lump. To take care of my babies, I had to stay at home, filled with anxious thoughts. After her surgery, when Bob left to pick her up, it was snowing heavily. Becky could barely walk, so Bob carried her.
They couldn't get in the door easily because Becky was wearing a big, hard plastic cone(圆锥体) around her neck to prevent her from licking her sutures (伤口缝合线). I held the door wide open. She was sad and crying. There was snow inside her cone. It took over five minutes to get them in because Becky shook her head wildly to try to remove the cone. The sound of the con e hitting the door made her panic and cry even louder.
Once inside, she was so frightened that she kept her tail between her legs. She thought she had done something wrong. Her expression said, “I’m sorry for what I did that led to me having to wear this.” Because of her surgery, Becky wouldn't take her special treat of a cube of cheese. She wouldn’t sit or lie down. All she did was stand and cry. “How long will she have to wear it ?” I asked. “Two weeks,” Bob replied.
“It’s my turn to take good care of her, just as she did for me years ago,” I thought.
Paragraph 1:Then, I stayed with her on the floor, helping her get through her firs tough night.
