Singapore is building an airport where indoor trees, waterfalls and a 'rain vortex' sit alongside check-in queues, waiting rooms and baggage carousels(传送带).

    Where once sat a car park, there will soon be thousands of trees and plants across 22,000 square metres of landscaped indoor parklands. This will be joined by a 40m-high indoor waterfall, expected to be the world's tallest. These are the plans for the new 3.5 hectare 'Jewel' development at Singapore's Changi Airport, scheduled to open in 2018; a five-story, 134,000 square metre complex, mixing natural outdoor plants with modern airport facilities.

    “The aim behind the introduction of such lush(茂盛的) landscaping is purely to provide all visitors with a memorable experience, one where they are surrounded by nature and greenery,”says Philip Yim, Chief Executive Officer of Jewel Changi Airport Development.

    Promised sustainability（持续性） measures include “extensive usage of photovoltaic panels（光电板）”to produce renewable energy, as well as encouraging the use of natural lighting and a “high efficiency” air-conditioning system.

    The indoor waterfall, named the “Rain Vortex”, will make use of special lighting effects to change at night into what is promised to be a dramatic light and sound show. “The Rain Vortex is one example of how sustainable design plays an important role in the planning of the attraction,” says Yim. 'In the event of a rain storm, the power of the rain water will flow naturally through the oculus. The excess rain water collected will be used for irrigation of the landscaping at Jewel.'

    Yim quotes the popular reputation Singapore enjoys as “the garden city”, where greenery is recognised as an essential part of the urban landscape, an attractive image which clearly inspires Jewel's design.

    However, it remains to be seen whether, beyond the aesthetic (审美的) appeal, Jewel can add genuine environmental things to something as un-environmental as an international airport.

A Blessed Teacher

    I remembered Ricky came back to see me ten years after he was in my class. He told me how I had inadvertently(不经意地) changed his life.

    Ricky often gazed out the window during one of my ninth-grade history classes early in my teaching career. He was quiet, and his good grades and mild manner were why I did not move him away from the seat by the window.

    One day, I leaned over his shoulder and quietly asked, “What are you looking at? You gaze out of this window during every class.”

    He said, “I am looking at the band.”

    According to Ricky, I said, “If you like the band so much that you have to look at them during this class every day, I want you to go down to Mr. Overby (the band teacher) and tell him that I sent you. Tell him that you want to be in the band. Now turn around and finish working before the bell rings.”

    The next day Ricky went to Mr. Overby and told him I had sent him and he wanted to be in the band. He added that he did not know how to play any instrument.

    When Ricky visited me ten years later, he thanked me for telling him to go to Mr. Over by because he fell in love with music and discovered his musical talent that had not been tapped. His musical talent resulted in him getting a scholarship to college and earning a degree that now allowed him to provide for his family. Most of all, music had brought great pleasure and satisfaction to his life.

    After Ricky thanked me, I pointed out that he did all of the hard work it took to become the wonderfully talented person that he was. I did not make him walk downstairs to join the band, practice his instrument, and get the good grades that led to his college scholarship.

    Ricky responded that I could have yelled at him for looking out the window. Instead, I gave him an alternative that changed his whole life.

    After he left, I thought about his words. I realized that I was teaching children with every word I said, every action I took, and with every decision I made. Ricky's story raised my teaching bar. Most of all, I have never forgotten the lesson Ricky taught me, a blessed teacher.

    Last summer, two nineteenth-century cottages were rescued from remote farm fields in Montana, to be moved to an Art Deco building in San Francisco. The houses were made of wood. These cottages once housed early settlers as they worked the dry Montana soil; now they hold Twitter engineers.

    The cottages could be an example of the industry' s odd love affair with "low technology," a concept associated with the natural world, and with old-school craftsmanship (手艺) that exists long before the Internet era. Low technology is not virtual (虚拟的) —so, to take advantage of it, Internet companies have had to get creative. The rescued wood cottages, fitted by hand in the late eighteen-hundreds, are an obvious example, but Twitter's designs lie on the extreme end. Other companies are using a broader interpretation (阐释) of low technology that focuses on nature.

    Amazon is building three glass spheres filled with trees, so that employees can "work and socialize in a more natural, park-like setting." At Google's office, an entire floor is carpeted in glass. Facebook's second Menlo Park campus will have a rooftop park with a walking trail.

    Olle Lundberg, the founder of Lundberg Design, has worked with many tech companies over the years. "We have lost the connection to the maker in our lives, and our tech engineers are the ones who feel impoverished (贫乏的) , because they're surrounded by the digital world," he says. "They're looking for a way to regain their individual identity, and we've found that introducing real crafts is one way to do that."

    This craft based theory is rooted in history, William Morris, the English artist and writer, turned back to pre-industrial arts in the eighteen-sixties, just after the Industrial Revolution. The Arts and Crafts movement defined itself against machines. "Without creative human occupation, people became disconnected from life," Morris said.

    Research has shown that natural environments can restore(恢复) our mental capacities. In Japan, patients are encouraged to "forest-bathe," taking walks through woods to lower their blood pressure.

    These health benefits apply to the workplace as well. Rachel Kaplvin, a professor of environmental psychology, has spent years researching the restorative effects of natural environment. Her research found that workers with access to nature at the office—even simple views of trees and flowers—felt their jobs were less stressful and more satisfying. If low-tech offices can potentially nourish the brains and improve the mental health of employees then, fine, bring on the cottages.

    The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.

    Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.

    Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.

    The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.

    To raise money for the idea, he toured the City's private companies which fund new businesses and found a supporter in the finance group Mint. He introduced his idea to four of Mint's directors and won their support. Mint has committed around ￡500,000 to MyHab and taken a share of 30 per cent in Mr. Dunlop's business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.

    Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.

    For music events, the cardboard houses will be ordered online and put up at the sites by the Myhab team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior(外部的) advertising space.

    The biggest festivals attract tens of thousands of participants, with Glastonhury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.

    We have recently heard some interesting ways that 5G wireless technology might change our lives in the future. One project in Britain is testing this superfast technology, but not on humans. Instead, the experiment involves an unlikely group of Internet users—cows. The system connects the animals to 5G in an effort to automate the milking process.

    The project was developed by American technology company Cisco Systems. It is part of a Cisco-led program called 5G Rural First. Cisco says the program seeks to explore the future of 5G connectivity in rural communities around the world. Rural areas are expected to be the last to receive 5G service.

    Testing areas were set up on farms in three rural areas of England. The cows are equipped with 5G-connected devices that link up to a robotic milking system. The system uses sensors and machine learning to fully automate the process, System designers say the technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each individual cow. It then positions equipment to the right body position for milking. During the process, machines release food for the cow as a reward.

    One of the test areas is in the town of Shepton Mallet, in southwest England. There about 50 of the farm's 180 cows are fitted with 5G smart collars and health-observing ear sensors. Project officials say the devices do not harm the cows and the sensors permit farmers to immediately identify any problem or health concerns.

    Other technology tools powering the 5G smart farms include automated brushes that work automatically when the cow rubs up against them. Sensors also control the amount of light to the cows' living areas depending on the weather. And, an automatic feeding system makes sure the animals always get enough to eat.

    Nick Chrissos works on the project for Cisco. He said the system could connect every cow and every other animal on the whole farm. "That's what 5G can do for farming—really release the power that we have within this farm, everywhere around the United Kingdom, and everywhere around the world."

Elizabeth Bishop is considered one of the best American poets of the 20th century. She was born in Worcester, Massachusetts in 1911. Her dad died when she was just a baby and her mom never recovered from the loss; she went to live with her grandparents in Nova Scotia, Canada when she was five. Eventually Bishop attended Vassar College, where she began to write poetry.

At Vassar she discovered Marianne Moore's poetry and met "Ms. Moore" and began their life-long friendship. She later met poet Robert Lowell. She wrote tons and tons of letters to both of them, which is good for us because we would otherwise know very little of her personal life. Bishop's poetry is sometimes considered objective and cold because it shows almost nothing about the poet or her life.

Bishop published her first book of poetry in 1946 and wrote until her death in 1979. She would spend years working on a single poem. Her poems are not the result of hasty scribbling (匆忙乱写) on paper while eating breakfast. Over a lifetime of writing, she only published about 275 pages of poetry, and about 40 of those are translations. She would look through drafts of poems again and again and improve them until they were as close to perfect as she could get them.

Reading Elizabeth Bishop is like being transported to the very place, the very moment she's writing about. She leads us to a microscope so we can see every smallest part of the scene. It seems she's always asking us to notice more, and more until the poem is so clear in our minds that it's almost painful — like a light that's too bright. It might take your eyes a while to get used to it, but once they do, you'll like what you see.
