On the school playground in Los Tomes, José, a lone child, plays a ballandcup game. The eightyearold is the school's only pupil. His teacher, Nilda, herself a former pupil, says that enrolment(注册入学) has dropped from 65 when she started teaching 43 years ago. Drought has driven families away, she says, “Only the old remain.”
Los Tomes is an agricultural cooperative, one of 178 in Chile's Coquimbo region. Nineteen communities try to grow wheat and raise sheep and goats on 2,800 hectares. A decadelong drought has made that harder. Hilltop springs where the animals once drank have dried up. As the number of herds(畜群) decrease, farmers' children moved away to take jobs in cities or at copper mines.
① Hope for Los Tomes comes in the form of three 60squaremetre nets stretched between poles on a ridge(山脊) above the community. These nets capture(捕捉)droplets(水珠) from the fog that rolls in from the sea 4 kilometers away. They flow down to two troughs(槽), from which animals drink. The nets can harvest 650 litres of water a day.
② Chile has been investigating fog capture since the 1950s. The fog can be harvested with the help of a coastal mountain range and strong winds. Earlier attempts to turn the mist into usable water failed. In 1990 fog nets at a fishing village captured 8,000 litres a day. Villagers argued about how to share responsibility for maintaining the nets.
Climate change, which is expected to decrease rainfall in the region, has inspired a new search for sources of water. The project at Los Tomes is part of an attempt to capture fog. “The question is not whether the fog collectors work but who's going to provide and maintain them,” says Daniela.
At a community north of Los Tomes, three 150squaremetre fog catchers feed a plantation of young olive trees. When the trees mature, they will produce 750 litres of organic olive oil a year. The water source will be a big selling point. A privately owned brewery(啤酒厂)in Pena Blanca was quick to spot fog water's marketing appeal.
③ The development fund paid 5.6 million pesos each piece to put up the structures in Los Tomes；when the nets wear out, the villagers will have to replace them at a cost of 100,000 pesos each. Coquimbo has more than 40,000 hectares of land with the right conditions for putting up fogcatchers. If it were fully employed, the region could harvest 1,400 litres a second, enough to supply all its drinking water.
④ That might attract back educated young people from the cities. A chance to develop tourism near the Fray Jorge national park, a rainforest which has survived thanks to its own natural fogcollection mechanism, brought Salvador to his birthplace. “Roots, the land and the desire to start this brought me back, says Salvador.

How sharks navigate the vast and seemingly featureless ocean has long been a mystery. Now there's evidence they may follow their noses. Sharks rely on their sense of smell to help chart a path through the ever-shifting waters of the deep seas, according to a new study. Scientists have supposed that the animals navigate by monitoring smell clues or the Earth's magnetic field, but no one knew for sure.
In new experiments near San Diego, scientists ferried wild leopard sharks about 6 miles(10 kilometers)away from their preferred habitats, fitted them with tracking devices, and stuffed some of the animals' noses with cotton balls. Just 30 minutes after being released facing the wrong way, sharks with full use of their smells made a corrective U-turn and then headed straight back to shore, "says study leader Andrew Nosal, a researcher at the Scripps Institution of Oceanography, California. Sharks with stuffed noses, meanwhile, "appeared lost, "wandering aimlessly and
swimming more slowly than those that could smell freely.
To test sharks' sense of direction, Nosal and colleagues captured several dozen leopard sharks, a small species found along the coast from Washington State to northern Mexico.
After blocking some of the animals' noses, the scientists then took the animals on a cruise to deeper waters before slipping them, safe and unharmed, back into the sea. Even the sharks with plugged noses made it partway back to shore before their tracking devices fell off. But those with unplugged noses "took very straight paths" toward home. Nosal supposes the sharks likely sniffed out chemical molecules found in higher and higher doses nearer to land.
Other scientists, however, remain unconvinced. Maybe the animals with plugged noses "were confused by the fact that they had something stuffed in their nose," says Kim Holland, a marine biologist at the University of Hawaii at Manoa. It's also unlikely the animals were following a smell that grew stronger closer to land, adds Jayne Gardiner, a sensory biologist at the New College of Florida. Animals that couldn't smell a thing still turned toward the beach, which "suggests something else is really guiding them," she says.
Study leader Nosal responds that sharks with cotton-stuffed nose willingly eat, suggesting that a congested nose doesn't upset them much. He agrees that sharks use a variety of markers to find their way, "but the point is that smell participates in navigation, "he says. "Our study was only the first step in solving this mystery. "

A hospital has been forced to ban Pokemon Go players from the site after a monster hub (妖怪枢纽站) was found in the A&E department. Royal Stoke University Hospital discovered that its casualty unit(急诊室) is on the same spot as a Pokemon Go ‘gym’ —— where players can train their newly caught Nintendo creatures.
The University Hospitals of North Midlands Trust agreed last week that patients can play Pokemon Go on wards because walking around is healthy. But the Trust has been forced to post a warning on its website about public access to A&E. It said if Pokemon Go becomes a major annoyance it would ask Nintendo—— which decides on the locations of the virtual gyms according using GPS——to have it removed from the premises(道馆).
Kevin Parker, associate chief nurse, said, “Members of the public who do not need to be at Royal Stoke should not attempt to enter A&E or any other part of the hospital building to play the game. The A&E department is incredibly busy this summer. We want the public to understand that anybody who visits the hospital solely to play the game will provide an unwanted distraction to the important work of the hospital. I’m also aware of various reports in the media of unsafe areas that the game has been played in.”
“Royal Stoke University Hospital is a safe area where gamers can enjoy Pokemon Go.” Michelle Harris, the Trust’s manager, said the game could still be played by those already in hospital. “We recognize that the Pokemon Go game encourages walking and exercise, which is something that the Trust is equally keen to promote,” she said.
There are a number of “walking routes” established throughout the Trust that can be used to combine walking and playing the game. “Walking just 30 minutes, five times a week, can help reduce the risk of preventable illnesses such as obesity, diabetes, and heart disease.”
There have been several warnings about the game since its UK release. Last week a group of teenagers in Wiltshire were left stranded almost 100ft underground after they got carried away searching for Pokemon Go characters. The four boys, aged 16 and 17, ended up getting lost and had to wait to get a phone signal before they could call for help. Eventually, they contacted Dorset and Wiltshire Fire and Rescue team, who took them to safety. Damien Bence, of the fire and rescue team, said: “Pokemon Go is obviously leading people into dangerous situations.”

For many years my parents subscribed to “Reader’s Digest”. Usually I enjoyed reading each issue(期) as much as they did. The _______ in the magazine I liked most was “The Best Advice I Ever Had.”
Even today, one of those best advice stories sticks with me and _______ a great lesson. Writing about his _______. Harry Fosdick—longtime beloved minister of Riverside Church in New York City— _______ a morning when his father was leaving the house. He _______ to Harry’s mother and said “Tell Harry he can cut the grass today, _______ he feels like it.” Then after a few steps the father turned back and _______ a meaningful suggestion: “Tell Harry he had better feel like it.” The reason why I treasure Fosdick’s father’s instruction is that many of us know what we have to do in our _______ tasks —we are told what to do, while the major _______ is that in many cases we delay action until we feel like it.
So think of the ________ that Harry’s father tells him that he “had better feel like it” when we must do the ________ things. Already, I am confident you could add a dozen similar ________ tasks and responsibilities to this list—possibly two dozen. If you ________ until you feel like doing them, tasks will become more difficult. Getting back to young Harry’s task, I can ________ that a small boy pushing the mower(割草机) with great effort back and forth, around flowers and bushes on this ________ day, wiping the sweat from his face until he got the job ________. Let’s be aware that this was one of those long ago mowers, ________ a motor, appropriately called “push mowers.” So the task is ________. Harry got the demanding job finished, because he knew that he “had better feel like it.”
________ you are to finish your task or do your work, you’ll have to feel like it. After you ________ feel like it you’ll surprisingly find it isn’t difficult to finish.
