When an endangered seabird hits a power line, it ________ “very much like the laser noise from Star Wars,” says preservation biologist Marc Travers. He should know, as his team from the Endangered Seabird Recovery Project recorded thousands of hours of audio to determine if power lines ________ local seabirds. Travers was trying to establish how ________ birds were killed by power lines on the island of Kauai in Hawaii in 2011.

His team recorded 600 hours of audio and sent the recordings to Preservation Metrics, a company that assists preservation efforts with AI ________. Preservation Metrics used a program to “listen” to the recordings and check off the sounds that signified bird electrocutions (电击). The result was ________, as the number of bird electrocutions was in the thousands. ________ proof that power lines were killing a significant number of birds, the team worked with the local utility (公共设施) service to reduce bird deaths.

In science fiction stories such as The Matrix, AI-powered machines take over the world and end life on the planet as we know it. But ________, programs that use AI to sort through mountains of data might just save some species from disappearing permanently.

By many ________, humans have been poor keepers of the planet. Humans have altered as much as 97 percent of land ecosystems. Key populations of monitored animals have declined as much as 68 percent since 1970. The decline in ________ around the world has created a miserable situation. Preservation efforts ________ key resources they need to be effective.

Humans, ________, fortunately have AI-based tools that can help now. AI can quickly and accurately sort through large amounts of data created by observations in the field. Then other programs such as PAWS (Protection Assistant for Wildlife Security) can help analyse the data and suggest the most effective ways to focus preservation efforts.

In large national parks and wildlife reserves, ________ hunters are a danger for animals both big and small. Some animals are worth a lot of money on the black market. Park keepers are left with a(n) ________ task because there is too much land to cover. But the PAWS programme allows park keepers to focus their efforts. PAWS has even ________ the existence of trap lines in areas not yet watched by park keepers!

We still face many challenges to ________ the loss of wildlife, but AI-powered programs promise to be a powerful preservation tool.

Running and good causes have always gone __ — just think of all the fundraising marathon runners do. But there couldn’t be a more on-trend way of keeping fit than plogging.

Anything that’s getting people out in nature and connecting __ with their environment is a good thing, says Lizzie Carr, an environmentalist who helped set up Plastic Patrol, a nationwide campaign to __ our inland waterways of plastic pollution. There’s been a real __ in the public mindset around plastics, helped by things like Blue Planet highlighting how disastrous the crisis is,” she says.

We need to keep momentum high and the pressure up, and empower people through __ like plogging and Plastic Patrol.

The plastic Patrol app allows users to __ plastic anywhere in the world by collecting discarded items, photographing them and __ to the app, giving us a better knowledge of what sorts of plastic and which brands are being thrown out. “I’d urge all ploggers to get involved,” adds Carr.

Plogging isn’t the first fitness trend to combine running with a good cause, Here are some of our favourites:

Good Gym

【推荐1】A pirate’s life no more

HONEST souls intent on paying for the music they listened to used to have a hard time in China. In the era of compact discs, _______ was the shop which did not sell pirated（盗版的） ones. The same held true when discs turned into downloads and online streams of songs: hardly any _________ charged money.

Yet this is changing. Slowly, but _______, China is becoming a market where people pay for music. Over the past five years, digital-music revenues for the recording industry nearly quadrupled, to $195m; most of that amount comes from music streaming (see chart). That sum may still be a tiny fraction of the global total of $7.8bn, but streaming has clearly taken off in China.

Not everybody is paying: of the 600m Chinese who listen to music online only 20m have a paid subscription, which costs between 8 and 12 yuan a month. The rest _______ for nothing, but many do so on legal, advertising-supported services. “Piracy is _______.” says Ed Peto of Outdustry, a firm in Beijing offering services to the music industry.

If Chinese consumers have developed a liking for _______ listening, it is for a combination of reasons. Smartphones, which have become popular in recent years, make it easy to _______ to streaming services. Widespread use of apps such as Alipay and WeChat Pay mean that younger Chinese, in particular, are now used to making small purchases _______. And, to take advantage of the commercial opportunities in music, China’s big internet platforms have begun to fight piracy.

Not all is _______, however. The streaming market is ________ by one player: Tencent, the largest of China’s online giants, which is best known for its WeChat messaging service. According to some estimates, its market share exceeds 70%. Each of the company’s two leading streaming brands, QQ Music and KuGou, ________ hundreds of millions of users.

One cause for this market concentration is acquisitions: last year Tencent bought two big competitors. More important, ________, it has paid three major international record labels—Warner Music Group, Sony Music and Universal Music Group—a big, but unknown, sum for the ________ right to stream their music in China. This means that Tencent gets to decide which songs rivals are ________ to play.

Tencent executives say that they need such exclusivity to ensure the legitimacy of streaming services and to reduce piracy further. But having one firm have so much power “is never healthy”, says an executive at a rival firm. With the market growing quickly, the labels may ________ their deals with Tencent when they come up for renewal.

【推荐3】We hear between 10 and 200 lies every day, from “Sorry, my phone was dead” to “I’m fine.” And just by listening to simple linguistic _______, we could easily discover them, claim scientists and linguistics experts.

Studies have shown that stories based on _______ experiences are different from those based on real experiences, suggesting that coming up with a lie takes work and thus _______ a different pattern of language use.

In a TED Talk, Noah Zanden, a science communicator and chief executive of Quantified Communications based in Austin, Texas, explained how “linguistic text analysis”—which is based on the difference between how we _______the truth and lies--- can help people spot untruths.

There are four common patterns in the subconscious language of lying. Zanden explained that liars typically _______themselves less and talk more about others in a lie than usual. They sometimes use the third person to _________ themselves from their lie, because they subconsciously feel guilty. For the same reason, liars tend to be more _______. “For example, a liar might say, ‘Sorry, my stupid phone battery died. I hate that thing,’”Zanden said. People can also spot a lie when someone explains events using very _______ words. Our brains struggle to build a complex false story, which means that explanations about events that didn’t happen seem _______ straightforward. ________, although liars may keep their story simple, they tend to use longer and more complicated sentences, __________unrelated but factual sounding details to make their story sound more believable, he said.

Experts say that the patterns can be seen in famous ________. For example, when seven-time winner of the Tour de France, Lance Armstrong, ________using performance-enhancing drugs in 2005, he described an unreal situation ________ someone else to disassociate himself from his lie. In contrast, when he admitted to using them in 2013, his use of first-person pronouns increased by nearly three quarters, ________that he was telling the truth. He talked about his focus on personal emotions and motivations.
