2 . Landscape architect Kotchakorn Voraakhom has designed a new green roof on the Rangsit Campus of Thammasat University, about 25 miles north of central Bangkok, Thailand. Her imaginative work challenges the common thinking that urbanization has a negative impact on the planet, whether flooding, excess (过度的) energy use, disrupted (扰乱) biodiversity or the heat island effect.

The 236, 806-square-foot structure, which opened in December 2019, includes a flood water management system and Asia’s largest rooftop organic farm. It combines modern landscape architecture with traditional agricultural knowledge, creating a green and friendly environment.

The green roof, containing an H-shaped landscape, looks like a futuristic hill with a brick building beneath it. The hill features a complex pattern of zigzagging terraces (之字形梯田) of planted beds, leading all the way down to the bottom. When rainwater hits the roof, it flows down the zigzags while being absorbed by the soil in the beds, The excess water is directed into four storage ponds — with a capacity of up to 3 million gallons. The process slows down the flow speed of rainwater runoff compared to a normal concrete rooftop. This keeps the area from flooding during heavy rains.

The roof’s terraces are filled with organically grown crops, including a drought tolerant variety of rice, many local vegetables and herbs. The farm can supply the canteens on campus with a large amount of rice, herbs and vegetables a year. The food waste is composted (把……制成堆肥) to fertilize the farm, and water from the storage ponds is used to water plants, creating an entirely localized and circular system.

The farm serves as an outdoor classroom and a source of local jobs, too. Farmers offer workshops on sustainable agriculture and nutrition as part of the university’s sustainability curriculum. “Students and community members are invited to participate in seasonal seeding, harvesting, and so on,” says Voraakhom. “The urban farm is training a new generation of organic farmers with real-world skills. It also promotes a sense of community.”

4 . Many people enjoy spending their vacations swimming, lying in the sun and staying at luxurious hotels.     1     They head for the country, to one of the numerous United States national parks, and take advantage of the fresh air and many outdoor activities that nature has to offer.

“I’m a successful lawyer from San Francisco,” says Gavin Murphy. “    2     I usually go to Yosemite National Park, where I sleep in a tent, hike, and enjoy the peace and quiet.”

    3     They can go fishing in a cold stream, hiking on a winding nature trail, or biking along scenic paths. At certain times of the year, guided nature walks and interesting lectures on a variety of topics are offered to park guests.

Camping out does have its disadvantages, however.     4     Even after the weather clears up, there’s still lots of mud to deal with. The weather can be quite cold at night, and there are always many mosquitoes (蚊子).

Park rangers (护林员) recommend that visitors watch out for snakes, whose bites can be poisonous. They stress the fact that it is necessary that food be kept packed away, so that an unexpected bear doesn’t pay an unwelcome visit to some surprised guests.     5     “It might be nice to sit by a swimming pool and sip (小口抿) a drink,” says Tanya Rodriguez, a nature lover, “but nature is really so beautiful, and I’ve met such interesting people here. Nothing compares to a vacation like this!”

5 . Summer is always a busy travel season, but even at peak times like July, that doesn’t necessarily mean you’ll see lots of hotels with No Vacancy (空房) signs. More and more travelers are choosing instead to stay in vacation rentals: decorated private houses, rooms, or apartments that only you and your party share for the period of your stay. Or you can get adventurous and book a cabin, a tree house, a houseboat, or even a castle.

The idea appeared in 2007, when Brian Chesky and Joe Gebbia, the owners of a hotel, realizing that a San Francisco tech meeting would make hotel rooms in the area harder to come by, let travelers sleep on air mattresses (充气床垫) in their apartment for a fee. They called it Air Bed and Breakfast, and the company—now known as Airbnb—is worth almost $100 billion today and has six million listings worldwide.

More space is a major attraction of this accommodation (住宿): the average hotel room measures just 330 square feet, while the average vacation rental room tops 1,300. And in 20 of the largest U. S. cities, average daily rates are comparable to (or slightly lower than) those of hotels.

If you’re willing to share your own digs while you’re away, Love Home Swap pairs you with like-minded travelers for stays in each other’s homes for a membership fee as low as $ 11 per month. If you’d like to list your home, check your local zoning laws, as some areas have strict rules on short-term rentals. In parts of Honolulu, a new law taking effect in October will up the minimum stay to 90 days.

6 . Mammoth Cave National Park, in the state of Kentucky, is a unique and historical natural wonder. It has the world’s longest cave system. There may be another 600 miles of cave passageways that have yet to be explored. In addition, more than 200 caves that are disconnected from the larger system can be found in the park.

The underground caves were created naturally by the process of limestone (石灰岩) erosion. Rain and rivers slowly dissolve (溶解) and shape soft limestone. The system is still being shaped today. Not only are they an amazing destination to visit, but the system also provides drinking water for about 40% of the US population.

The caves’ first explorers were Native Americans, who mined (采矿) the upper levels of Mammoth Cave. Later, the sites were left in great shape and began to draw public interest.

Mammoth Cave was made into a national park thanks to strong support. Back in the 1920s, the Southern Appalachian National Park Commission was set up in 1925. After years of work, as well as building roads and public facilities, the park was completed on July 1, 1941.

The park now receives around 2 million visitors a year, with about a quarter taking a tour of the caves—everything from a cultural tour to the more adventurous tours on offer. The cave supports more than 130 wildlife species (物种). The park is also much more than just a cave; the forest around has a diverse (多种多样的) range of species. There are miles of trails open for horseback riding, with canoe trails and great fishing spots. There are also more than 1,300 flowering species in the forest, and animals like wood warblers, thrushes, and bald eagles can regularly be seen.

7 . Standing on a hill at Cliveden Gardens on a sunny winter day, its dark-green lake surrounded by centuries-old trees took my breath away.     1     It’s just a local park near London that I’d never heard of during my eight years living in the UK. As I admired the serene garden, it taught me a lesson about the British culture of understatement.

“The English landscape is more beautiful because its beauty is understated,” my friend Will said to me later as we walked through an exhibition at Tate Britain. He pointed to a painting of a peaceful countryside. “This is the landscape I grew up with”, he said. Unlike grand waterfalls or wild forests, this scenery doesn’t shout about its beauty.     2    

I wonder if Chinese tourists will explore beyond London.     3     Indeed, Oxford and Cambridge and the beloved Lake District National Park are some iconic symbols of Britain. But it would be a pity if they miss out on the lesser-known parts of the English landscape.

    4     I remember a straight-A classmate once telling me he “survived exams” and another friend from Oxford introducing himself as “studying in the countryside”. This modesty also has its mirror in Chinese culture. I remember my parents’ telling me to work hard but not to brag about my achievements. Chinese culture is full of proverbs such as “real gold will shine sooner or later”, to encourage long-term dedication to one’s chosen area of expertise.

Experiencing both cultures, I’ve realized that the English and Chinese both express achievements with understatement.     5     It reflects the unspoken charm in both British and Chinese traditions. And it’s an off-the-beaten-path attraction well worth exploration.

9 . Best Family Vacations in the Caribbean

Choosing a Caribbean vacation that meets the needs of young children, preteens and adults might seem like a challenging task. The following introduction may provide you with some choices.

With three islands to choose from, U. S. Virgin Islands appeal to families who like to combine beach time with a bit of exploration. Virgin Islands National Park on St. John offers this combination — and more — with 20-plus trails and access to popular Trunk Bay beach. Kids will also enjoy Coral World Ocean Park on St. Thomas, where they can swim with dolphins and sea lions.

Beautiful beaches, magnificent reefs and opportunities for horseback riding and surfing lessons make the Bahamas a family favorite. Plus, this string of 700 islands boasts plenty of budget- and family-friendly resorts. One of the most famous resorts — Atlantis Paradise Island — even has its own 141-acre water park and the world’s largest open-air marine habitat for the young to enjoy. At the marine habitat, travelers can enjoy watching various aquatic animals swim by.

Grand Cayman, the largest and most popular of this three-island chain, offers families tons of ways to enjoy their time together. Adults and kids can sunbathe, build sandcastles and float in the Caribbean Sea at Seven Mile Beach, or swim with stingrays (刺魟) in the shallow water of Stingray City. To get up close and personal with more sea life, head to the Cayman Turtle Centre to interact with turtles of all shapes and sizes.

Calm waters and pollution-free beaches attract travelers of all ages to the British Virgin Islands. While the destination can be pricey, families can save money by splashing around Smuggler’s Cove, a free beach known for its sea turtles and relaxing atmosphere. Visitors will also enjoy themselves in the Baths National Park.

10 . In 1983, Ski Rixen USA became the first water ski cable park in the United States. Located in Deerfield Beach, Florida, the park offers riders a chance to experience all kinds ofwater sports.

In the past 40 years, Six Rixen USA has welcomed more than 1.5 million visitors. The park was the brainchild of engineer Bruno Rixen. Born in 1931 in Germany, Rixen grewfrustrated with the sport of water skiing, which required pulling by a motor boat.

“He used to wait for four hours in line to do three laps around the lake, ” explained Allan Wlodarczyk, the manager of Ski Rixen USA. He added that riding five minutes and waiting another four hours sparked Rixen’s idea of cable parks. Rather than relying on a boat, Rixen considered his own cable way. He also designed skis and set up a power source.

“The first cable was actually an old farm tractor, ” Wlodarczyk said. “Rixen took the wheels off, attached some ropes to the wheel disks, and started pulling people back and forth around the lake.” Over the years, Rixen improved his design and earned several patents. He opened the world’s first commercial cable water park in 1966 in Benidorm, Spain.

The sport grew from entertainment to international contests. Rixen died in 2020, but his idea has taken hold around the world. Today, there are more than 500 cable water parks on different continents. Typically, the cable tows riders at a speed of about 20 miles per hour.

But for beginners, who can take lessons, the speed is about 15 miles per hour.

Ski Rixen USA also offers riding opportunities and events to people with special needs to ski effortlessly. “We have a specially designed ski, called a sit ski,” Wlodarczyk said. “It’s a larger board with a lot of surface area. The riders are completely seated in the water and don’t actually have to hold onto the rope.”
