Airports are dull places where bored passengers kill time eating rubbish food they don't want and buying stuff they'll never need. Right?

    Wrong! Many of today's terminals（航站楼）around the world offer great entertainment, dining and shopping. With so much to offer, you're almost attracted to miss your flight.

    ⒈Changi Airport, Singapore

    It's the only one in the world with its own butterfly garden, and each of the three terminals has its own indoor playground and video game area.

    If you have a long wait you could always watch the latest movies at the free cinema, go to sunflower gardens or take a dip in the rooftop swimming pool.

    ⒉Incheon Airport, Seoul, South Korea

    A five-minute free shuttle bus ride will take you to the SKY72 Golf Club, with three courses and a driving range.

    There are seven gardens inside the terminal, an ice rink, a spa and the Museum of Korean Culture. There is even a casino（赌场）.

    ⒊Dubai Airport, UAE

    It has its own health club with a Jacuzzi, gym and swimming pool, or you can wander in the Zen Garden. The weary can take a rest in a sound-proofed pod with a bed for a while.

    ⒋Hong Kong Airport

    Not only does it have its own IMAX cinema, the airport is home to Green Live AIR, a hi-tech space offering both nine and 18-hole golf simulations（模拟）.

    For kids, there's the Dream Come True Education Park, where they take part in role-playing jobs, or the Aviation Discovery Centre, with themed exhibits and graphics, and the Sky Deck runway viewing platform.

    ⒌Munich Airport, Germany

    Go to the outdoor Visitor's Park to check out the historic aircraft, watch the planes from the viewing hill or browse in the souvenir shop. For kids, there's Kinderland, a fun paradise with a big “adventure plane”, films, games, arts and crafts, and a waiting room for their tired parents to relax in.

    And, of course, since we're in Bavaria there's a beer garden!

    Mom noticed that something was wrong when I started getting so thirsty. I'd have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I'd drunk the entire container! My mom called my doctor. I then had a few blood tests, and the results were certain — I had diabetes (糖尿病), which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.

    My eating habits had to change in a big way. With diabetes, I can't eat a lot of sugar or carbohydrates (碳水化合物). I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin (注射胰岛素) before the meal to help my body process the food. Also, I test my blood-sugar level often. I'm always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn't keep me out of gym class or off the basketball court — I just keep some juice boxes around to boost my blood sugar if I need to.

    It's a lot of work and not a lot of fun to keep track of everything, but I've gotten used to my new habits. I was a little scared at first because I wasn't sure how my life would change. Once I knew what I needed to do, though, it wasn't a big deal. My life is different now from what it was before, but it has become completely regular to me.

    It's 8 a.m., Tuesday, Nov. 18, 2028, and you are headed for a business appointment 300 miles away. You step into your circle, two­passenger air­cushion car, press a series of buttons and the national traffic computer notes your destination, figures out the current traffic situation and signals your car to slide out of the garage. Hands free, you sit back and begin to read the morning paper — which is flashed on a flat TV screen over the car's dashboard. Tapping a button changes the page.

    The car speeds up to 150 mph in the city's countryside, and then hits 250 mph in less built­up areas, driving over the smooth plastic road. You fly past a string of cities, many of them covered by the new domes (圆屋顶) that keep them evenly climatized all year round. Traffic is heavy, typically, but there's no need to worry. The traffic computer, which sends and receives signals to and from all cars on the road between cities, keeps vehicles at least 50 yds apart. There hasn't been an accident since the system began.

    Suddenly your TV phone buzzes. A business partner wants a sketch of a new kind of impeller your firm is putting out for sports boats. You reach for your case and draw the diagram with a pencil­thin infrared flashlight (红外线闪光灯) on what looks like a TV screen lining the back of the case. The diagram is sent to a similar screen in your partner's office, 200 miles away. He presses a button and a fixed copy of the sketch rolls out of the machine. He wishes you good luck at the coming meeting and signs off.

    Ninety minutes after leaving your home, you slide beneath the dome of your destination city. Your car slows down and heads for an outer­core office building where you'll meet your colleagues. After you get out, the vehicle parks itself in a garage to await your return. Private cars aren't allowed inside most city cores. Moving sidewalks and electrams (电车) carry the public from one location to another.

    Play time is in short supply for young children these days and the lifelong consequences for developing children can be more serious than many people realize.

    An article in the most recent issue of the American Journal of Play details not only how much children's play time has declined, but how this lack of play affects emotional development, leading to the rise of anxiety, depression, and problems of attention and self control. “Since about 1955, children's free play has been continually declining, at least partly because adults have applied ever-increasing control over children's activities.” says the author Peter Gray, Ph. D, Professor of Psychology at Boston College.

    We can describe the unstructured freely-chosen play as a testing ground for life. It provides critical life experiences without which young children cannot develop into confident and competent adults. So kids need more of it, not less. Because play is how young children learn important social and emotional skills such as sharing, cooperating, communicating, and empathizing. It helps them develop fit bodies, strong minds, and brave hearts, so they can take on new challenges and risky situations.

    Gray's article is meant to serve as a wake-up call regarding the effects of lost play. We must know that lack of childhood free play time is a huge loss that must be paid attention to for the sake of our children and society. But parents who keep a lookout over and disturb their children's play are a big part of the problem. It is hard to find groups of children outdoors at all, and, if you do find them, they are likely to be wearing school uniforms and following the directions of coaches while their parents dutifully watch and cheer.

    Actually, when children are in charge of their own play, it provides a foundation for their future mental health as older children and adults. Play gives children a chance to find and develop a connection to their own self-identified and self-guided interest. It is through play that children first learn to make decisions, solve problems, improve self-control, and follow rules. Play helps children make friends and learn to get along with each other as equals. Most importantly, play is a source of happiness.

When parents realize the major role that free play can take in the development of emotionally healthy children and adults, they may wish to reassess the priorities ruling their children's lives. The needs for childcare, academic and athletic success and children's safety is important. But perhaps parents can begin to identify small changes——such as openings in the schedule, backing off from quite so many supervised (有监督的) activities, and possibly slightly less keeping watch on the playground that would start the slow returning to the direction of free, imaginative-directed play.

Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.
