1 . Where do you expect to see graffiti (涂鸦)? Probably not in a museum. Bristol Museum and Art Gallery, in the south-west of England, was the kind of place you went to see classical statues and stuffed animals in cases until the arrivals of the ‘Banksy Versus the Bristol Museum’ exhibition in 2009. The exhibition hosted more than 100 works by Banksy, one of the world’s most famous graffiti artists.

Banksy is a man of mystery (神秘). He hardly ever gives interviews and likes to be anonymous (匿名的). Nobody knows much about his life or his background but many people believe that his real name is either Robin Cunningham, Robert Banks or Robin Banks and that he was born in 1973 near Bristol.

Banksy’s questioned ‘street art’ includes paintings on live sheep and cows and graffiti on the huge wall put up to divide two areas. Brand Pitt spent over 82 million on a Bansky original. Banksy designed an album cover for the Britpop group Blur in 2003 but he has refused requests to do adverts for Nike. A year after the Bristol exhibition, Banksy made a film called Exit Through the Gift Shop. The film tells the story of a French street artist in America. Exit Through the Gift Shop received many positive reviews. Nobody knows if it was about a real artist or an invented character from Banksy’s imagination.

Bristol isn’t the only place in Britain to welcome graffiti. The DPM Park in Dundee, Scotland has the longest legal graffiti wall (almost 110m long) in the UK. Anyone can paint on the council-owned wall any time they like. Mike Crilley, the graffiti wall project organiser, promotes the positive side of graffiti and runs workshops for local children.

Is everyone doing graffiti? Can we do graffiti where we want these days? Not exactly. It’s illegal to paint on somebody else’s possessions, so make sure you find a legal graffiti wall like the one in Dundee if you want to have a go.

2 . Hawaii lawmakers are considering legislation (立法) that would require visitors to pay for a year-long license or pass to visit state parks. Josh Green is the state’s governor. He said, “We get between 9 and 10 million visitors a year, but we only have 1.4 million people living here.” He added, “Those 10 million travellers should be helping us sustain our environment.” Lawmakers still debating how much they would charge.

The governor campaigned in 2022 on the idea of having all tourists pay a $50 fee to enter the state. Legislators think this would violate US constitutional protections for free travel. They instead think visitors should pay to enter parks and trails. Either policy would be a first of its kind for any US state. Hawaii’s leaders are following the example of other popular tourist areas with similar fees or taxes. They include Venice, Italy, and Ecuador’s Galapagos Islands.

Hawaii State Representative Sean Quinlan is the leader of the House Tourism Committee. He said changes in the activities of travellers are part of Hawaii’s push. He said golf rounds per visitor per day have dropped 30 percent over the past 10 years while hiking has increased50 percent. People are also seeking out isolated places they have seen on social media. The state does not have the money to oversee and protect all these places, he said.

Most state parks and trails are currently free. Some of the most popular ones already charge, like Diamond Head State Monument. That trail leads hikers from the floor of a 300,000-year-old volcano up to the top. It gets 1 million visitors each year and costs $5for each traveller.

A bill currently before the legislature would require visitors over the age of 15to buy a yearly pass to visit forests, parks, trails or “other natural area on state land”. People who live in Hawaii would not need to pay.

3 . All three of my children were subject-matter experts before they even left primary school. My eldest son memorized every statistic on every football trading card he got his hands on. His brother knew hundreds of car makes and models by heart. And I’m sure that my daughter — a huge One Direction fan — remembered more facts about the band than they did! The experience of becoming an expert can bring long-term benefits for learning — and it’s never too late. “Having a specialist subject helps you learn anything,” says our memory expert, Jonathan Hancock, “There are good reasons for all of us to do a spot of specialist learning.”

It schools our observation: a vital first step to remembering. Children are particularly good at seeing slight differences — like my younger son and his cars — then using them to organize information and inspire recall. But focused learning like this can push anyone to start noticing key details — ready to remember them.

It gives us a mental framework (框架), to which we can attach unrelated ideas. Even when his trading-card period was over, my son often linked new numbers with stored-away sports statistics. Your own area of interest might help you by suggesting soundalike words for people’s names, or letting you “map” travel directions.

It gets us learning in a variety of ways, often with the help of all our senses. My daughter’s pop knowledge was a rich mix of music, dances and colourful costumes, with precise facts. Burying yourself in a subject boosts your brain to work at its best.

It restores our confidence to remember. We get to see what a difference it makes to be interested in something, to build up information in layers (层次), and to keep refreshing, testing and showing off what we know. It can give all our learning a boost.

Why not pick a topic that interests you, find some books, take a course, join a club... and enjoy becoming at least an entry-level expert? Even a short spell of specialist study can reawaken learning skills that used to feel like child’s play.

4 . Health, as the old saying goes, is over wealth, so it’s of great significance to keep fit. You can take away our money, our house, or our clothes and we can survive.     1     That is why I eat healthfully, exercise regularly, and keep up my social life.

Eating healthfully is important to maintain one’s health. I try to avoid foods high in fat like French fries or cookies. I also try to limit the amount of animal protein I consume.     2     So, it is important to know how to cook these foods so that the nutrients are not lost in the cooking process.

Our muscles must continue to be strong to support our body as we age. Exercise helps the bones build density and helps us maintain our posture.     3     A regular exercise program of cardiovascular training and weight training is an important part of keeping us healthy.

    4     Studies have shown that people with a wide range of social contacts get fewer colds and recover faster from diseases than those who aren’t socially active. For the sake of health, I like to play and interact with my friends and I always feel better when I am with them than when I am alone.

By eating properly and exercising regularly, I can keep my body at an appropriate weight and can maintain my health. By spending time with my friends, I can keep my mind as well as my body happy.     5    

5 . Being a plastic-free gardener is an important step for having an eco-conscious garden. Here’s how to garden by using alternatives to plastic plant pots.

Lots of pots

    1    . Most are made of plastic, and come in a variety of colours. None of these plastics are readily recyclable. Half a billion plastic pots ended up in landfill or being burned each year.

Plastic-free plant pot alternatives

The great news is that, the choice of alternative plastic-free pots is fantastic.     2    .

Ceramic (陶瓷) pots

Though expensive, when it comes to plant pots, there is not much that compares to the appeal of hand-made ceramic pots. Ceramic pots are made from the firing of clay.     3    . Therefore, if collected steadily over the years, they become the backbone of any working garden, offering a ready pot for a month or two of growing on;a permanent home for repeat-flowering flowers lasting for seasons; or a decorative feature for a greenhouse.

Wool pots

Made from raw washed wool pots, these cute little pots are a very attractive natural alternative to plastic.       4    , but they also make a perfect pot for decorative plants that will sit in a striking position while they are growing larger — a great talking point for plastic-free gardening.

Hemp (麻) pots

Hemp pots are a great alternative to the plastic pots used to grow tomato and potato plants.     5    . They come in a range of sizes, from around five to forty litres (公升). Hemp pots develop from a sustainable source, are fully broken down and can be reused for several seasons.

7 . Teachers work hard to care equally about each of the students they teach. For most of us, however, some students stand out because they have greatly influenced our lives. Years ago, I had a young boy named Juan in my first-year class who I will never forget. Our experiences together impressed upon me the huge influence that just a few minutes of kindness can have on a young life.

Juan came from a very poor, single parent home. His mother showed little interest in his education and in his life in general. Throughout the year, I noticed that Juan had an unusual ability to solve questions and he picked up new ideas fast. I was surprised when he approached me to tell me that he did not think he was smart enough to attend college.

I explained to Juan that he was one of my best students. His face lit up with excitement, and he looked at me delightedly. I went on to explain to him that he could apply for scholarships (奖学金) to pay for college. I continued by telling Juan that it would be a waste of talent if he did not go to college. Juan looked as though he would need to re-think his whole life. It was not surprising that he was finally awarded enough scholarship that he was able to attend the local university.

My love for my students and for the subject I teach has continued to grow over the years. I consider myself lucky to be a teacher, and to have been a part of so many young lives, hopes, and dreams! I may not drive the nicest car on the block, but I am very rich in the things that count the most.

8 . Accents in English

Accents are fascinating and usually come with kinds of information.     1    . So many people, especially actors, are interested in learning accents.

Thanks to the development of technology, various handy accesses are available for people to share and pick up accents. English actor and accent coach Sarah Valentine is an expert in teaching the tones which can change the English language.     2    .

Valentine has been working in TV since the 1990s. She appears to have found success coaching other actors to speak in a variety of dialects.     3    , TikTok is a medium to educate the masses. Valentine’s TikTok takes simple phrases, such as “I’m hungry” or “the milk smells funny”. Valentine then repeats these simple words in accents including German, Dutch, and New York. She also highlights the rich variety of dialects within the UK, including Yorkshire, Scouse, Cockney, Geordie, Welsh, and Northern Irish.

“    4    ,” James Lantolf, a professor at Penn State, said. “Isolated (偏僻的) areas, such as New Orleans, develop different dialects. Since there is no contact between regions, entire words and languages can grow and develop independently. Social standing and education also affect the language of an individual person.” It is thought that accents have psycho-social purposes, allowing individuals to identify oneself and others as part of a group.

Everyone has an accent. A dialect coach like Valentine can help one learn to speak differently, for an acting job or for fun.     5    . Learning a second language as an adult is difficult; for much the same reason, it’s tricky to change your accent. With that in mind, watching Valentine change accents at the drop of a hat is all the more impressive.

9 . There is growing evidence to show that our past knowledge about Mars was not always the case. Now European researchers say they have discovered the first evidence of a huge groundwater system that once existed below the planet’s surface.

A new study was carried out by Francesco Salese and his team, who studied images of 24 deep craters (n.弹坑) in the northern half of the Red Planet. These pictures were captured by ESA’s Mars Express orbiter (n.宇宙飞船), which was launched in 2003. The study provides the first geological proof that Mars once had a “planet-wide groundwater system.”

According to Salese, scientific evidence already suggests Mars was once a watery world. His team says the images showed that large amounts of successive groundwater activity connected the areas they studied. Evidence of basins and coastlines was also found on the surface of Mars, supporting the idea that water was once present. He added that all the basins seemed to reach about the same height.

Scientists have yet to find out what happened to all that water. And the complex history of water on Mars has linked to whether or not life ever existed on it. During the latest study, researchers also discovered evidence of minerals within some of the identified (adj.被识别的) bodies of water.

The researchers say the findings adds weight to the idea that the water basins on Mars may have once held the materials required to support life. Some of this material could still be buried on Mars, providing possible evidence of life during future exploration. Francesco Salese believes the latest findings could also help us learn new things about our own planet.
