Maples are known for their autumn colors. Many species put on a display of oranges, browns, yellows, and reds every year. Here are four excellent species of maple for your landscape.

As the name suggests, the leaves are quite large on this tree. It has the biggest leaves of any maple; the classic palm-shape leaves can be over 12 inches wide. This large tree is an excellent shade tree for large landscapes and parks.

The hedge maple is a great choice for the urban garden, as it does well in many severe environments: drought, salty soils, shady locations, and climates where there is ozone deficiency. It can also be used as a street tree if the power lines are high enough.

Known either as Norway maple or European maple, this popular species was brought to North America from Europe in the 18th century. It has since become one of the most common trees. In the right settings, this species may become invasive (侵入的), so before planting it, check to make sure it is not a problem in your region.

Many species of plant within a genus have a similar appearance, but there can be surprises, as is the case with the hornbeam maple. Its leaves are nothing like what you expect from a maple. This can be a somewhat difficult plant to find for sale, but it can make a good   small tree or a large shrub (灌木) in the landscape.

From a fish and chip stall, Jenny has come to be the toast of London’s foodie scene. She has achieved a remarkable feat by becoming a famous chef, a distinction that has been a dream coming true for her. “It’s still sinking in,” she said, expressing her surprise at the overwhelming social media response to her accomplishment.

Her restaurant is a unique space where modern West African cuisine takes center stage, highlighting the rich culinary (烹饪的) traditions of Nigeria’s Hausa, Yoruba, and Igbo ethnic groups. “In my restaurant, I bring together these three culinary traditions, providing an exciting journey for diners,” Jenny described. Each dish tells a story, from a black sauce for fish, a postpartum (产后的) meal for new mothers, to a fermented tomato sauce.

Jenny’s love for food began at a young age, but she was initially guided towards a more traditional career path. She studied biological sciences in university, where she also ran a fish and chip cart. Her move to the UK in 1999 marked the beginning of her journey towards culinary success.

As for her, her restaurant is not only a restaurant but also Jenny’s way of honoring her heritage and the food her grandmother used to prepare. “The memory of my grandmother’s cooking inspires me every day,” she shared. Jenny’s cooking shows heartfelt respect for her roots, and her mission is to showcase the flavors of her culture.

Jenny longs to be a role model for chefs from diverse backgrounds. She recognizes the value of representation and hopes her success can inspire other chefs in the UK. She notes that while the industry is slowly becoming more inclusive, it’s crucial for employers, landlords, critics, and investors to expand their perspectives to support a variety of cuisines.

Her fame is a testament (证明) to her talent and dedication, but it’s the personal connection to her dishes and the memories of home-cooked meals that truly fuel her passion. Jenny’s story is a shining example of how one can achieve their dreams while staying true to their cultural identity.

Are aliens trying to contact the Earth? Six new mysterious blasts of radio energy are detected from deep space. While the source of the waves remains unknown, some suggest the mysterious bursts of energy could be a sign of alien life trying to contact us. The waves were detected by researchers from McGill University in Montreal.

The detection follows 11 previously recorded fast radio bursts (FRBs) from the same location, called FRB121102. This is the only known repeater of FRBs. Although there have been a number of FRBs from the site, the origin of the radio bursts remains a puzzle to researchers.

But the researchers say that the repeated FRBs imply that whatever is causing the FRBs is not a one-time event, such as an explosion or a collision. Instead, they say that flares (耀斑) from a young neutron star (中子星) are a promising candidate.

Previously when waves have been detected, astronomers have also asked Search for Extraterrestrial Intelligence (SETI) to take a closer look at whether they could be a message from aliens. But it is unclear whether the researchers will ask SETI to help this time.

If there were any intelligent alien life forms out there, in Stephen Hawking’s opinion, we were playing a dangerous game by trying to contact them. If alien s discovered the Earth, they would likely want to conquer and colonize our planet.

But the co-founder and former director of the SETI Institute, Jill Tarter, doesn’t think this will be the case. She argues any alien s who have managed to travel across the universe may be friendly and peaceful. “The idea of a civilization which has managed to survive far longer than we have... and the fact that the technology remains an aggressive one, to me, doesn’t make sense,” she said.

Imagine a world where nothing ends up in landfill. Instead, everything can be reused and recycled, creating products that never reach their “end of life”. According to a recent report by the Circle Economy Foundation, only 7.2% of all used materials are being cycled back to be reused and recycled without creating waste.

An Italian company aims to change this by creating furniture products made from a plastic-like biomaterial, which is fully organic and biodegradable (可生物降解的), and can be used over and over again. Using fruit peel, orange seeds and coffee grounds collected from businesses in Italy, the company can redistribute products to the same businesses for use in their offices, instead of furniture made from common plastic. If, by mistake, any of the material ends up in the ocean, it doesn’t produce any microplastics.

Each product is made through a four-step process. First, the food waste is dried and crushed into a very fine powder. Then, the powder is mixed with a biodegradable plastic alternative known as polyhydroxybutyrat (PHB), with the fruit waste making the PHB more study (坚固的). The material is then turned into a filament (细丝) and, using a spool, put into a 3D printer.

Because a lot of food waste would be buried and incinerated in the landfill, which would produce lots of carbon dioxide, Reusing fruit peel and coffee grounds decrease carbon dioxide from the production of plastic, according to the director of operations in the company. He adds that the biomaterial is as sturdy as wood, and won’t begin to break down unless it’s touched by water, bacteria or acidity.

Despite its eco-friendly benefits, the biomaterial is expensive. It costs probably six times more than common plastic, and it is a very difficult and expensive process, so this is why many companies aren’t doing it.

However, the director is hopeful that in a few years, as-more consumers and businesses are forced to face the damage that unsustainable plastic is doing to the planet, the biomaterial will be much more widely used. “We really believe this is the material of the future,” says the director. “Little by little, a step at a time.”

The community is the basic unit where we share space and resources with others. A harmonious and orderly community not only enhances the quality of life for its residents but also promotes stability and development in society. Therefore, community residents should understand and fulfill their responsibilities and duties to ensure a harmonious and beautiful community environment.

The cleanliness of the community environment directly affects the health and quality of life of its residents. Residents should avoid littering, actively participate in community cleaning activities, and regularly clean their own doorsteps and surroundings. Additionally, properly sorting waste and participating in recycling are essential duties for every resident.

    17    . Every resident should observe public order and not disturb the peace of the community. This includes controlling noise from household activities, avoiding loud noises at night or on rest days, and following traffic rules by not parking illegally or speeding within the community. Moreover, residents should treasure public facilities and not damage plants or trees, collectively maintaining the community’s beauty and functionality.

Actively participating in community management is;an important responsibility for residents. This includes voting for community leaders, participating in community meetings, and offering suggestions and feedback on the management and activities of the community. Residents can also join volunteer organizations, take part in community safety patrols, and organize cultural events.     18    .

Good neighborly relations are the foundation of a harmonious community.     19    . Each should be willing to help, and provide extra care and assistance to the elderly, children, and disabled individuals. When facing neighborhood disputes (纠纷), residents should approach the situation with understanding and tolerance and resolve issues through communication and negotiation.

Community safety affects everyone’s interests. Residents should increase their safety awareness and report suspicious behavior and safety hazards (安全隐患) promptly.     20    . Using them, residents can protect themselves and assist others in emergencies.

A piece of fossil sponge (海绵) that formed during the early Cambrian period was recently discovered in Changde, Hunan Province.

The     41     (discover) fossil sponge can date back to 540 million years ago. It ranges around 4 centimeters in     42     (high) and 3.5 centimeters in width. Paleontologist (古生物学家) Zou Hesi told the Global Times that the size is giant for a sponge from that period of time.

“Sponges become bigger and bigger over time; another fossil piece     43     (date) back to around 300 million years ago was also recently discovered in Ireland, for example. It was about 50 centimeters,” Zou told the Global Times. Found near the Cliffs of Moher, the piece     44     (name) as “Cyathophycus balori”. It is so far the largest known fossil sponge in the world.

    45     4-centimeter Chinese piece was unearthed     46     (unexpected) during a field survey that local researchers were conducting in the Taoyuan District, Changde. Tong Guanghui, a research fellow at the Hunan Museum of Geology,     47     (tell) the media that the team found a piece of rock on their way     48     research destination in the town of Sanyanggang.

“So we stopped, and used a geological hammer     49     (examine) the piece. It was unearthed in such a complete condition,     50     made us all thrilled about the discovery,” said Tong.
