1 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.
Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.
“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).
Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.
Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.

4 . By day, Robert Titterton is a lawyer. In his spare time though he goes on stage beside pianist Maria Raspopova — not as a musician but as her page turner. “I’m not a trained musician, but I’ve learnt to read music so I can help Maria in her performance.”
Mr Titterton is chairman of the Omega Ensemble but has been the group’s official page turner for the past four years. His job is to sit beside the pianist and turn the pages of the score so the musician doesn’t have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.
“A lot of skills are needed for the job. You have to make sure you don’t turn two pages at once and make sure you find the repeats in the music when you have to go back to the right spot.” Mr Titterton explained.
Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of “nodding” to indicate a page turn which they need to practise with their page turner.
But like all performances, there are moments when things go wrong. “I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand,” Mr Titterton said, “Luckily I was able to catch them and put them back.”
Most page turners are piano students or up-and-coming concert pianists, although Ms Raspopova has once asked her husband to help her out on stage.
“My husband is the worst page turner,” she laughed. “He’s interested in the music, feeling every note, and I have to say: ‘Turn, turn!’ Robert is the best page turner I’ve had in my entire life.”

5 . Goffin’s cockatoos, a kind of small parrot native to Australasia, have been shown to have similar shape-recognition abilities to a human two-year-old. Though not known to use tools in the wild, the birds have proved skilful at tool use while kept in the cage. In a recent experiment, cockatoos were presented with a box with a nut inside it. The clear front of the box had a “keyhole” in a geometric shape, and the birds were given five differently shaped “keys” to choose from. Inserting the correct “key” would let out the nut.
In humans, babies can put a round shape in a round hole from around one year of age, but it will be another year before they are able to do the same with less symmetrical (对称的) shapes. This ability to recognize that a shape will need to be turned in a specific direction before it will fit is called an “allocentric frame of reference”. In the experiment, Goffin’s cockatoos were able to select the right tool for the job, in most cases, by visual recognition alone. Where trial-and-error was used, the cockatoos did better than monkeys in similar tests. This indicates that Goffin’s cockatoos do indeed possess an allocentric frame of reference when moving objects in space, similar to two-year-old babies.
The next step, according to the researchers, is to try and work out whether the cockatoos rely entirely on visual clues (线索), or also use a sense of touch in making their shape selections.

6 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?
1. What does paragraph 2 mainly tell us about mobile phones?A.Their target users. | B.Their wide popularity. |

7 . Who is a genius? This question has greatly interested humankind for centuries.
Let’s state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?
In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It’s said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color or belief—they were unacknowledged and rejected by others.
A study recently published by Science found that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn’t take a genius to know the answer: absolutely not.
Here’s the good news. In a wired world with constant global communication, we’re all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”

8 . When I was 9, we packed up our home in Los Angeles and arrived at Heathrow, London on a gray January morning. Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.
Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don’t worry about it. Once, when trying a certain trick on the beam(横杆), I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “ Safe! Safe! Safe!” And that’s what mattered—landing tricks, being a good skater.
When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I’d given it up.
When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I’ve traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch the skaters. Weaving(穿梭)among the kids who rushed by on their boards, I found my way to the beam. Then a rail—thin teenager, in a baggy white T—shirt, skidded(滑)up to the beam. He sat next to me. He seemed not to notice the man next to him. But soon I caught a few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man. Safe.”
“Yeah,” I said. “Safe.”

9 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

10 . A Take a view, the Landscape(风景)Photographer of the Year Award, was the idea of Charlie Waite, one of today’s most respected landscape photographers.Each year, the high standard of entries has shown that the Awards are the perfect platform to showcase the very best photography of the British landscape.Take a view is a desirable annual competition for photographers from all comers of the UK and beyond.
Mike Shepherd(2011) Skiddaw in Winter Cumbria, England | It was an extremely cold winter’s evening and freezing fog hung in the air. I climbed to the top of a small rise and realised that the mist was little more than a few feet deep, and though it was only a short climb, I found myself completely above it and looking at a wonderfully clear view of Skiddaw with the sun setting in the west. I used classical techniques, translated from my college days spent in the darkroom into Photoshop, to achieve the black—and—white image(图像). |
Timothy Smith(2014) Macclesfield Forest Cheshire, England | I was back in my home town of Macclesfield to take some winter images. Walking up a path through the forest towards Shutlingsloe. a local high point, I came across a small clearing and immediately noticed the dead yellow grasses set against the fresh snow. The small pine added to the interest and I placed it centrally to take the view from the foreground right through into the forest. |
