Super typhoon Rammasun swept over Hainan, China, destroying at least 23,000 houses and causing 2 billion dollars in damage. It was not just people who experienced the impact, though. In Hainan Bawangling National Nature Reserve, home to the world’s 30 remaining Hainan gibbons(长臂猿), landslides tore through sections of the forest. The gibbons, a species living in trees, were forced to jump across a distance of up to 50 feet to get from one area to another.
The gibbons sometimes would break their fall only by managing to catch hold of the tip of a particular palm leaf. As months passed, Bosco Chan at the Kadoorie Farm and Botanic Garden in Hong Kong noticed that constant use caused the leaf to wear and bend downward, threatening to lead to the gibbons crashing down and breaking the extremely rare species’ habitat into different islands. “It’s really a matter of concern. Moreover, I didn’t know how long the leaf would be able to hold the gibbons,” he said. “I thought it was time for us to build something.”
As recently described in Scientific Reports, Bosco Chan and his colleagues turned to aerial(空中的) bridges. They hired professional tree climbers to confront and get over the steep landform to fix a simple bridge, consisting of two parallel mountaineering-grade ropes. It took the gibbons over five months to catch on, but once they learned to use the ropes, they started regularly using them to make safe, quick crossings.
Till now, aerial bridges have been used in other countries to help a diversity of animals ranging from squirrels to capuchin monkeys. But many are small, one-off projects carried out by local organizations or even individuals; with little or no scientific study of what does or does not work. In addition, a solution for one species or habitat may not be applicable to another.

【推荐1】Robert Irwin is a typical teenage boy, who enjoys mountain biking and photography. He also lives in a large zoo.
Robert, the son of the late “Crocodile Hunter” star Steve Irwin, is now taking center stage in “Crikey! It’s the Irwins, ” a new series on Animal Planet.
“We’ve worked on quite a few different TV projects, but this is actually the first time my whole family has come back to Animal Planet together, so it’s pretty unusual, ”says Robert.
Premiering(首映)at 8 p.m. on Sunday, “Crikey! ” follows the Irwins as they run the 100-acre Australia Zoo, founded by Steve Irwin’s parents. Steve owned and ran the zoo before he died in 2006.
“We’ve always grown up in front of a camera. Bindi, my sister, and I were both filmed for some of the original ‘Crocodile Hunter’ documentaries, ”says Robert.
“I’m very lucky in the way that I’ve had so much of my life captured on camera, so as the memories you have of Dad start to fade, you can always look back at the old footage and relive those special moments, ” he says.
“Crikey! It’s the Irwins” has some footage of Steve. The most exciting part of the premiere involves Robert leading the “ Croc Show" at the zoo’s “ Crocoseum, ”a 5,500-seat stadium Steve built to give crocodile performances and educate visitors about crocodile behavior.
Of course, running a zoo doesn’t leave much time for school, so Robert participates in Distance Education, a program similar to homeschooling. “School can be difficult for me to fit in, ” he says. “But I've actually got a classroom that’s set up at Australia Zoo and a teacher that travels with us wherever we go, so I can fit in all of my studies. ”
Robert continues, “I’m learning as much as I can about all of the animals and all of the work at Australia Zoo. I feel really honored to be following in Dad’s footsteps. I love continuing that work. ”

【推荐2】Most of us spend our lives seeking the natural world.We go fishing,sit in the garden,have a picnic,live in the suburbs or go to the seaside.The most popular leisure activity in Britain is going for a walk.When joggers jog,they don't run on the streets.Every one of them tends to go to the park or the river.
But despite this,our children are growing up naturedeprived.I spent my boyhood climbing trees.These days,children are robbed of the ancient freedom,due to problems like crime,traffic,the loss of the open space and strange new ideas about what is best for children,that is to say,things that can be bought,rather than things that can be found.
The truth is to be found elsewhere.A study in the US:families had moved to better housing and the children were assessed for ADHD—Attention Deficit Hyperactivity Disorder(注意力缺陷多动症).Those whose accommodation had more natural views showed an improvement of 19%;those who had the same improvement in material surroundings but no nice view improved just 4%.
ADHD is one of the great problems of modern childhood.One study after another indicates that contact with nature gives huge benefits to ADHD children.However,we spend money on drugs rather than on green places.
The life of old people is measurably better when they have access to nature.The increasing concern for the growing population of old people is in quality rather than quantity of years.And study after study finds that a garden is the single most important thing in finding that quality.Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
We need the wild world.It is essential to our wellbeing,our health and our happiness.

【推荐3】We see a woman swimming at night in a dark sea. Suddenly, she is pulled underwater. She surfaces, cries in fear, then disappears forever. This is the opening scene from the 1975 film Jaws, showing a shark attack. It tells the story of a great white shark that attacks and kills swimmers.
People have always been scared of sharks, but Jaws made things worse. It made people frightened of sharks, especially of the great white shark. Many people who saw the film started to believe that sharks were bad animals that ate humans. Some people stopped swimming in the sea, afraid of the horrible creature from the film. Other people started fishing for sharks, killing as many as they could. At that time, nobody cared if sharks were killed, or how many were killed. People just wanted them killed.
After 1975, the number of large sharks around America fell quickly, and soon fell around the world. This was not only due to fear of sharks, but also finning. Finning is a type of fishing where sharks are caught and their fins cut off. The sharks are thrown back into the sea where they die slowly and painfully. The fins are used in shark fin soup. Finning kills millions of sharks a year.
Finning would have an unexpected effect upon Peter Benchley, the man who wrote the book the film Jaws was based on. In 1980, Benchley was diving when he came across an awful sight. It was an area where fishermen were finning, and the sea floor was covered with dead sharks. Benchley saw sharks being killed and this caused a deep change in him. He came to see people as a danger to sharks, rather than the other way round. From that day on, he fought to protect sharks. He admitted that his book was wrong about sharks’ behavior. “Sharks don’t target humans,” he said. Experts have proved that sharks do not see people as food, and they attack us by mistake.
Fortunately, not everyone who watched the film Jaws became afraid of sharks-some became interested in understanding them. Today, as we learn more about sharks, more people than ever want to protect them from extinction.

【推荐1】A team of psychologists led by Dr. Karen McComb at the University of Sussex in the UK have discovered an effective way for humans to communicate with cats through slow blinking (眨眼睛), similar to how cats interact with each other.
Dr. McComb and her team conducted two experiments to study this phenomenon. In the first study, owners were instructed by researchers Tasmin Humphrey and Andrew Wood to slowly blink at their cats from a distance while being recorded. Humphrey and Wood found the cats were more likely to respond with slow blinking of their own compared to when no interaction took place.
To follow up on these findings, McComb, Humphrey, and Wood designed a second experiment without considering the exsisting relationship between humans and cats. Researchers, including McComb, performed the same slow blinking action. Like in the first experiment, the cats in this study also responded more favorably to slow blinking by returning the gesture and more readily approaching an extended hand, according to Humphrey’s analysis.
The slow blink expression involves partially closing the eyes briefly, copying a relaxed, friendly facial expression in humans. McComb notes that for cats, it appears to signal good intentions as constant staring could be seen as threatening. Wood says that cats may have developed this language to acknowledge humans who react positively to the signal. Being able to effectively communicate acceptance in this subtle cat way seems to strengthen the bond between cats and their owners, McComb adds.
McComb, Humphrey and Wood hope their findings can provide insight into cat behavior and thinking. They also aim to apply this knowledge of cross-species communication to evaluate cat health in various places like veterinary (兽医的) clinics and shelters, according to Humphrey. A deeper understanding of how cats interpret and respond to humans can improve our ability to properly care for household and outdoor cat populations, McComb concludes.

【推荐3】I grew up in California but have spent about four years living in various parts of the UK. The first thing I noticed was that my West-Midlands host family did not sound like the queen. I’ve since learnt that accents change almost every five miles. As far as America goes. I can tell the West Coast from the East or the South, but I can’t tell you a state, much less a county (郡).
The next thing I couldn’t imagine was the quiet, stare-ahead norm of public transportation- if you talk to somebody on the Tube, you’re probably a serial killer or a lost tourist.
I’ve had to deal with the Tube from Heathrow to Victoria with heavy bags more times and Victoria Station is not exactly tourist friendly. Each time I’ve had someone walk up and ask to help with my bags. Not once have they been English. In America, at least from what I’ve experienced, people will start a chat if they see you’re travelling by yourself, and I always immediately have someone taller offer to put my things in an overhead bin (行李箱).
Opening hours-especially Sunday trading laws have also taken so much to get used to. In America, 24/7 fast food, grocery stores. petrol stations, etc. are the norm. In my first year in the UK,I forgot it was Easter Sunday, and went into town at 2:00 pm. Imagine my surprise when 1 found the city center was deserted, and there wasn’t a single car at Tesco. Approaching the building, I saw a large sign announcing opening times. I had to make do with plain bread until 9:00 am Monday, when I’d be able to pay for groceries again.
Speaking of groceries, it took so many people telling me I was crazy to convince me to eat eggs here- they’re not refrigerated, and they’ll often have bits of feather or chicken waste on the outside. 1 am now aware that they ‘re safe, but coming from a childhood of perfectly clean, white, large AAA eggs, I was convinced I’d die a terrible salmonella (沙门氏菌) death.
