1 . 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.

2 . 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. |

3 . Life can change in the blink of an eye. For Bridgette Ponson, one of those moments took place in the parking lot at her workplace, Layton Christian Academy. While she was in the parking lot, her 2-year-old boy and 3-year-old girl in tow, a car hit them. This left the mother and her kids trapped beneath the car. Thankfully, the woman driver wasn’t driving very fast. At that moment, she was blinded by the sun. However, she got out of the car to help as soon as possible. Plus, she wasn’t the only one who stopped what they were doing to save Bridgette and her kids.
Soon, Chris Crowder, CEO of the school, became aware of the accident. Without delay, he united a group of students to help. “It was split second,” Chris recalled. “I immediately just ran into the building because I knew I had to get a lot of people to lift this car. The students just heard me shout. All students from different countries just ran out and lifted it up.”
Still, this wasn’t an easy task. The car was heavy. But the whole group of students worked together to lift the car enough for Bridgette and her kids to get free. Finally, one kid was flown to Primary Children’s Hospital while Bridgette and the other kid were taken by ambulance to the hospital. Although Bridgette took the brunt of the injuries, all three of them were expected to make complete recoveries within a few days. The heroic students who helped out certainly got their well-deserved praise.
“I’m very proud of our kids. They ran out without hesitation, and they just knew what to do without even being told what to do. I’m even surprised by the driver who was behind the wheel. She immediately ran to help,” said Chris.

4 . Tai chi is a wellness practice that combines slow, gentle movements and postures with mindfulness.
In the study, researchers in China randomly assigned 342 adults with prehypertension to one of two interventions. Roughly half the people participated in aerobic exercise, including jogging, climbing stairs and cycling.
After 12 months, those in the tai chi group saw bigger drops in their blood pressure than those in the aerobic exercise group. What’s more, nearly 22% of the people who practiced tai chi saw their blood pressure fall to within normal range.
Tai chi is appealing as a form of exercise because it is low impact and requires little space or equipment. “I think the beauty of tai chi is that you don’t have to have a special gym membership or special clohing, “ Taylor-Piliae says. “Once you learn tai chi, you can do it anytime, anyplace, anywhere.
| A．It can help reduce anxiety. |
| B．The other half was trained to practice tai chi. |
| C．It’s often called meditation (冥想) in motion. |
| D．So why does tai chi gain in popularity among people? |
| E．So what is it about tai chi that helps lower blood pressure? |
| F．By contrast, that number was 16% in the aerobic exercise group. |
| G．But you have to practice it consistently to gain the most benefit. |
5 . 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.”

6 . To produce the classic clothing, blue jeans, producers rely on indigo dye (靛蓝染料), the only molecule known to provide jeans’ unique, beloved color. While indigo itself naturally comes from a plant, growing demand for blue jeans throughout the 20th century gave rise to synthetic (合成的) indigo, which is now more commonly used.
Indigo is the dye that makes jeans blue, but it doesn’t mix with water. To dye clothes, usually, chemicals are needed to make the color stick to the cloth. But in Denmark, scientists have created a new way to dye clothes using an enzyme (酶), which is a kind of protein that can cause chemical reactions, instead of harmful chemicals. This new method is better for the environment and doesn’t use poisonous stuff.
The chemical process for dyeing blue jeans has persisted for the last century. Workers are exposed to the poisonous chemicals, which also pollute the environment near factories. Waste water from those factories often ends up in waterways, decimating local ecosystems and even dyeing rivers blue.
Ditte Hededam Welner, the study’s lead researcher, says their new enzyme works really well and is strong enough for making lots of jeans without breaking down. This enzyme makes dyeing with indican, which is like indigo, much less harmful to the planet — about 92% better than the old way.
However, the new method doesn’t fix all the environmental problems of making jeans. Making a single pair of jeans uses a lot of water — enough to fill many bathtubs — from growing the cotton to putting the final touches on the jeans.
Even though the new dyeing process is better for the environment, it’s not always easy or cheap to change to it. Welner’s team isn’t sure if jeans companies will find it easy or affordable to switch to this method. It costs a little bit more — just seven cents extra per pair of jeans — to use the enzyme for dyeing. But Welner believes it’s worth it because it’s much better for the environment.

9 . When you think of a map, is north on the top or the bottom? Usually, maps are designed with north on top, though when we think about it, there is no logical reason for this bias (偏见). After all, there is no up or down in space. So what is wrong with south, east or west being on the top of the map? The answer is: nothing at all. In fact, north-up maps only became the norm in the last few hundred years.
Ancient Egyptian maps had south at the top because the Nile River flows downhill from mountains in the south to the Mediterranean Sea in the north. Mecca was to the south of most early Muslim civilizations, and south-up maps were designed so that viewers would look up to see Mecca. Medieval Christian maps had east at the top, as they believed the Garden of Eden was in the east. The only early maps that had north at the top were those of early China because the emperor lived in the north.
North seems to have settled at the top of maps during the 16th century, largely thanks to a Flemish mapmaker, Mercator. Mercator was a great admirer of an early Greek mapmaker, who, for reasons now unknown, put north at the top of maps, so Mercator did, too. When Mercator’s world map became the standard map to navigate the oceans, north up became standard as well.
What is the implication of this north-view of the world? Psychologically, people tend to think of up as good and down as bad. Just think of words and phrases like “upmarket”, “upbeat” and “moving up in the world”, and how they contrast with their opposites. Because north is so consistently put at the top of maps, people now think of north as good, too.
Several attempts have been made in recent years by introducing south-up maps to the market. These maps not only give us a chance to see the world differently, but also give everyone the chance to see themselves on top.
1. What can we learn from the first two paragraphs?| A．North-up maps were rare in ancient times. |
| B．Deciding up or down in space is ridiculous. |
| C．Mecca maps were based on a legend. |
| D．The south-up map first appeared in ancient Egypt. |
| A．An illogical reason. | B．The spread of Mercator’s maps. |
| C．People’s preference for up. | D．An age-old tradition in Greece. |
| A．Cautious. | B．Supportive. | C．Uncaring. | D．Disapproving. |
| A．To criticize a phenomenon. | B．To compare various facts. |
| C．To correct a cultural bias. | D．To argue for a viewpoint. |
