Named after the “quest for heavenly truth”, Tianwen 1, China’s first Mars probe, has given us impressive pictures of the red planet. The first high-resolution(高分辨率的) pictures of Mars taken by Tianwen 1 were made public by the China National Space Administration (CNSA) ON March 4.
“These are the first close-up pictures of Mars’ surface taken by China,”said Bao Weimin, a scientist of the Chinese Academy of Sciences.
The probes shot high-definition pictures while traveling in Mars’s orbit, CNSA said. Craters, mountain ridges and sand dunes can clearly be seen. CNSA estimated that the largest crater in the picture could be about 620 meters in diameter.
The pictures were taken at different distances from Mars. The two black-and-white pictures were taken by the high-resolution camera on Tianwen 1 when the probe was about 330—350 kilometers above the Martian surface. As for the color picture, it was taken by Tianwen 1’s medium-resolution camera when the probe was about 5,000 kilometers above the red planet. It shows Mars’ North Pole.
“It is the shooting modes that determine if the pictures are black-and-white or colored,” said Liu Tongjie, deputy director of the lunar Exploration and Space Engineering of CNSA.
The high-resolution camera can take both color and panchromatic(全色的) pictures. Panchromatic pictures, which are black and white, are the clearest, containing the largest amount of data for scientific study, said Liu. The medium-resolution camera, although featuring automatic exposure(自动曝光) and remote control, can only produce lesser clear pictures. Scientists put the panchromatic and color pictures together to form a clear and beautiful color picture, Liu added.
Tianwen 1, the country’s first independent Mars mission, was launched on July 23, kicking off the nation’s planetary exploration program. The probe entered its preset parking orbit above Mars on Feb. 24 and is looking for a landing site on the planet’s largest plain, known as Utopia Planitia. The probe is expected to land on the red planet sometime between May and June.

[1]Water is important in our life, but sometimes water can be dangerous for kids. So we must pay attention to the kids’ safety in water. Water safety begins at home or in the pool. Here are some suggestions for you.
[2]Be（4）①________ of the hot water. Hot water can be dangerous, especially for kids under five. These young kids have thinner skin than older kids and adults, so it’s easier for them to be burnt（烫伤）. Staying in hot water that’s 60℃ for just 3 seconds can give a child a third-degree burn. You can reduce the risk by testing the water with your wrist（腕）or elbow before placing your kid in bath.
[3]Watch out for danger in the bathroom. The bathroom is full of danger for young kids. Never leave a young child alone in the bathroom, especially while he or she is bathing. Remember to put away hair dryers and all other electrical appliances（家用电器）to avoid the risk.
[4]Never let kids swim alone. Swimming in the water may make you feel great. As the kids move in the water, many small muscle（肌肉）groups are working to help them keep balance. But it’s not a perfect sport because of the risk of injury（伤害）. For example, many types of swimming need repeated arm movements. Over time, the movements can cause shoulder and neck injuries. So it’s dangerous when they stay in the water alone, they may even drown（溺亡）. So the kids are not supposed to swim（4）②________ their parents’ company（陪伴）.
[5]Everyone should realize the importance of water safety. （75）To keep the kids safe, we need to learn more about what we should do. After all, everyone（4）③________ only one life!

For most of us, the simple, cheap and common bicycle is just a means of transportation. But the United Nations sees it as a useful weapon to fight climate change.
On March 15, the UN General Assembly passed a resolution (决议) supporting bicycles as a tool for dealing with climate change. The resolution calls on member countries to include bicycles in public transportation options (选择). More cyclists mean fewer greenhouse gases. More specifically, it focuses on bicycle-sharing services.
The resolution is not surprising. On Feb 28th 2022, the UN brought out a new report on climate change. It warns that the global average temperature will rise by 1.5℃ above pre-industrial levels (1850-1900), with more than 40 percent of the world’s population “highly vulnerable (脆弱的)” to climate change.
The UN said transportation is the third-largest source of carbon dioxide (CO₂), a greenhouse gas that causes global warming. Choosing a bike over a car just once a day can reduce a person’s transportation carbon emissions (排放) by 67 percent, according to a University of Oxford study.
The UN resolution could be seen as an approval (认可) of China’s 14 years of bike sharing, noted CGTN. More than 360 Chinese cities have bike-sharing systems that deal with nearly 20 million bicycles for an average 47 million trips each day, said China’s Ministry of Transport. It reduces CO₂ by 4.8 million tons every year, according to a 2020 report from the World Resources Institute.
In fact, bikes have been booming worldwide since the COVID-19 outbreak. Cycling to work is a safer choice for many Europeans as they worry about getting infected (感染) on buses and subways. Plus, gyms had to close during months of lockdowns, so people turned to bicycles for exercise, reported China News. In Spain, in May 2020, bike sales increased 22-fold (倍) compared with 2019. In London, large parts of the city are being closed off to cars so that people can walk and cycle safely. Cities like Berlin and Montreal have also added new, wider bike lanes.

Three years ago, Cash Daniels was walking on a beach when he found some plastic. He started thinking about the effect plastic pollution has on the environment, especially on rivers and oceans. That’s when he got interested in environmental issues.
Cash, now 12, found that rivers are at the heart of the problem. A report in Science Advances said that far more rivers are carrying large amounts of plastic into our oceans than was once thought. This news hit close to home for Cash. He lives in Chattanooga, Tennessee. The city sits on the Tennessee River. It’s one of the most polluted rivers in the world. This information led Cash to take action. He made it his mission to clear garbage from public spaces and waterways.
At first, Cash and his parents worked to pick up garbage near the Tennessee River. But soon he realized he would need more help. So he organized community cleanup outings. Eventually, he and other volunteers removed more than 11,000 pounds of garbage from the river. Cash has also partnered with businesses to recycle plastic bottles and cans. He has recycled more than 2,000 pounds of them. The money he earned from that supported river protection efforts. Cash loves sea animals. By cleaning waterways, he helps protect these creatures.
He also set up fishing-line recycling containers(容器) along the Tennessee River. People can throw away their fishing line in these instead of in the water, where it entangles(缠住) wildlife.
Cash enjoys getting other kids involved in these activities. He wrote a children’s book called One Small Piece. It’s about pollution in waterways and oceans. Cash also co-founded the Cleanup Kids. The group encourages children not to throw away anything that can be recycled. “Kids may be small percentage of the population,” Cash says, “but they are 100% of the future.”

Building started in AD 122 and finished in AD 130, the Hadrian’s Wall goes across from the east to the west coast of northern Britain. It was built to control people entering the Roman Empire from what is now Scotland. A colorful new artwork was made last year to celebrate the Hadrian’s Wall 1900 Festival.
The artwork stands beside the remains of the Hadrian’s Wall. It is called The Future Belongs To What Was As Much As What Is. It is 9 metres wide and 16 metres tall. The artwork was designed by artist Myerscough, who is known for her bright and colorful creations. “The moment I stood in the remains and found they were unchanged from Roman times, I had an overwhelming feeling of wanting to make an artwork here. I knew immediately this was the right place.” said Myerscough.
Myerscough worked with the poet Ellen Moran and community groups to create the artwork. And the wall of the artwork is covered with small signs painted by local people. Some words and phrases on the signs were chosen by the poet Ellen Moran, such as “freedom”, “love” and “everybody’s welcome”. The artwork attracted lots of tourists. Anybody who visited would love it, because they could go inside it and look down, to see the same view as Roman soldiers had seen. It could help people see the Hadrian’s Wall from a different perspective.
As part of the Hadrian’s Wall 1900 Festival, the art celebration was open to the public until 30th October, 2022. After that, the artwork was completely removed and the signs were given back to the local people who helped paint them.
