I am a writer．I spenda great deal of my time thinking about the power of language—the way it canevoke(唤起)an emotion, a visual image, a complex idea, or a simple truth．Languageis the tool of my trade．And I use them all—all the Englishes Igrew up with．

Born into a Chinese family that hadrecently arrived in California, I've been giving more thought to the kind ofEnglish my mother speaks．Like others, I have described it topeople as "broken" English．But I feel embarrassed to say that．It hasalways bothered me that I can think of no way to describe it other than"broken", as if it were damaged and needed to be fixed, as if it lacked acertain wholeness．I'veheard other terms used, "limited English," for example．Butthey seem just as bad, as if everything is limited, including people'sperceptions(认识)ofthe limited English speaker．

I know this for a fact, because when Iwas growing up, my mother's "limited" English limited my perception of her．I wasashamed of her English．Ibelieved that her English reflected the quality of what she had to say．Thatis, because she expressed them imperfectly her thoughts were imperfect．And Ihad plenty of evidence to support me: the fact that people in departmentstores, at banks, and at restaurants did not take her seriously, did not giveher good service, pretended not to understand her, or even acted as if they didnot hear her．

I started writing fiction in 1985．And forreasons I won't get into today, I began to write stories using all theEnglishes I grew up with: the English she used with me, which for lack of abetter term might be described as "broken", and what I imagine to be hertranslation of her Chinese, her internal(内在的) language, and for that I sought topreserve the essence, but neither an English nor a Chinese structure．Iwanted to catch what language ability tests can never show: her intention, herfeelings, the rhythms of her speech and the nature of her thoughts．

    Forests are always losers at the Olympics, and that's unlikely to change anytime soon.

    For the winter games in PyeongChang, South Korea, virgin forest was destroyed on Mount Gariwang to accommodate ski runs. For the 2022 Winter Olympics in Beijing, a ski run is set to wipe out part of the Songshan National Nature Reserve. And let's not forget the 240 acres of Atlantic Forest that were leveled for the 2016 games in Rio de Janeiro to make way for a golf course.

    For the upcoming Tokyo games, environmental and human rights advocates have been raising alarms about the use of tropical (热带的) wood to build the New National stadium. Activists have fought against such environmental destruction. The damage is often permanent, threatens endangered plants and animals and in some cases, causes conflicts with native people. But frequently the country's organizing committee, and the International Olympic Committee (IOC) have found ways to make it reasonable — despite a paragraph in the Olympic Charter (宪章) that states that the IOC's role is to "encourage and support a responsible concern for environmental issues".

    "As it stands now, the IOC has little authority over a city's local organizing committee, which finally plans the event, " Chappelet, professor of public management at the University of Lausanne, told Earther. "Even if the IOC is dissatisfied with the way host cities have prepared for the games, they have no built-in systems to watch them so that they strictly follow the Olympic Charter." The only thing they can do if they're not happy is to withdraw (= take back) the right to organize the game. "But the IOC could include more enforcement (执行) systems into the contract they make with the host city," he added. That contract must be signed and obeyed by everyone and those who break it must be fined.

    Boykoff, the author of several books on the Olympics, suggested a similar solution. "The IOC could insist that host cities take their ecological (生态的) promises into account first, but instead they look the other way, time and time again," he said.

    Reintroducing beavers (海狸) to Britain could help clean up rivers, prevent flooding and minimise soil loss, an expert has claimed.

    Professor Richard Brazier, a researcher at the University of Exeter, said unpublished results from a trial area in Devon showed muddy water entering an area where beavers were living was three times cleaner when it left. "Our trial has shown that the beavers are able to dam our streams in a way that keeps soil in the headwaters of our catchment (流域) so it doesn't block up rivers downstream and pollute our drinking and bathing waters. If we bring beavers back it's just one tool we need to solve Britain's crisis of soil loss and agricultural pollution of waterways, but it's a useful tool," he said.

    Prof Brazier's claims were disputed by the National Farmers' Union (NFU), which warned that the reintroduction of beavers to Scotland had led to fields and forests becoming damaged. Spokesman Mark Pope said: "The knowledge of the impacts beavers have had on farmland, riverbanks and flood defences in Scotland is concerning. We await the results of the Devon trial and will analyse the outcomes then."

    Prof Brazier, an expert in Earth Surface Processes, insisted the animals could even play a useful role in preventing flooding. He told BBC News: "The public is currently paying people to build leaky dams to keep storm waters in the uplands. The beavers can do it free of charge and even build their own homes."

    However, Professor Jane Rickson, a soil specialist from Cranfield University, Bedfordshire, joined the NFU in sounding a note of caution. She agreed that in some places in the UK there was evidence of worrying soil loss, and said new policies were urgently needed. Beavers may in fact reduce the river channel and remove vegetation, exposing banks to greater erosion (侵蚀) and increasing, rather than decreasing, the risk of flooding, she warned. And she said beaver dams should be "leaky" to avoid build-ups of large volumes of water.

    Who can think of the race between the tortoise and the rabbit when it comes to the greatest races? Sure, that race only took place in ancient Aesop's mind, but while the great modern races can teach us a lot about commitment, perseverance (毅力) and the virtues of having a rather large engine, "The Tortoise and the Rabbit" may tell us everything about animals and even vehicles on this planet.

    In a study published this week, Adrian Bejan, a professor of mechanical engineering, concludes that no one should be surprised that the tortoise wins over the seemingly speedier rabbit. In fact, after analyzing the reported speeds of land-air-and-water-based animals, Bejan concludes that the world's well-known speedsters are actually among the slowest when their movements are averaged out over the course of a lifetime.

    The study builds on Bejan's previous research showing that an animals speed increases with mass regardless of species. And that principle can also be extended to non-living things, like aircraft.

    After studying data from historical airplane models, Bajan noted the speed of each model increased with its size, too. That doesn't sound right. What about the modern jet fighter? How is that relatively small craft not faster than a clumsy large transport plane?

    Again, Bejan harks back to the tortoise. That transport plane spends lots of time in the air, moving regularly across long distances. The fighter jet, on the other hand, may fly across the sky occasionally, but-like the rabbit-it's often found resting on the ground.

    The slow and steady transport plane wins the marathon of life.

    But like so many good stories, Aesop's tale offers even more than a lesson in perseverance.

    At one point, the rabbit asks the tortoise how he expects to win a race at such a slow pace.

    The tortoise—ever focused—doesn't respond But it's the rabbits own words that provide the moment to reflect on, especially in modem times.

    "There is plenty of time to relax," Until there isn't.

    Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored in different ways, researchers are discovering new rules. By tracking people's e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.

    "The 'if it bleeds' rule works for mass media," says Jonah Berger, a scholar at the University of Pennsylvania. They want your eyeballs and don't care how you're feeling. But when you share a story with your friends, you care a lot more how they react. You don't want them to think of you as a Debbie Downer."

    Researchers analyzing word-of-mouth communication—e-mails, Web posts and reviews, face-to-face conversations—found that it tended to be more positive than negative, but that didn't necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times' website. He and a Penn colleague analyzed the "most e-mailed" list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed tines' readers and made them want to share this positive feeling with others.

    Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, "Contagious: Why Things Catch on."

Four things that you can't miss in Macao

    Go Bungee Jumping at the Macao Tower

    The Macao Tower, 338 meters tall, is the world's 10th highest tower, with kinds of activities, such as eating and entertainment. One of the activities is the bungee jump. The Macao Tower Bungee Jump is 233 meters high, making it a Guinness World Record as the highest commercial bungee jump in the world. Raise your arms and off you go! If you are not daring enough to jump that height, you can try the sky walk on the 57th floor—it's still amazing. Take this chance and tick off this item on your list.

    Enjoy a traditional Portuguese dinner

    Macao was once colonized (殖民) by Portugal before 1999. As a result, Portuguese culture has deeply affected Macao.

    Many Portuguese settled and opened Portuguese restaurants here, but it is more adaptable to Chinese people.

    Visit a museum

    Macao, as a little city with only an area of 30.5 square kilometers, has 23 eye-catching museums. Due to its special history, both eastern and western historical relics can be found. Many of them are preserved for cultural relics, tourist spots or museums, such as the Grand Prix Museum, Maritime Museum and Wine Museum.

    Go into an entertainment place

    Well known as the "Las Vegas of the Orient", Macao has 33 entertainment places. You can find different themed entertainment places with their hotels and attractions around every corner of Macao, especially on Taipa Island. Among all, The Venetian is the most popular. With a huge shopping mall and Vegas-style design, it is a must-go place for both tourists and locals to shop and enjoy free time. So when you come to Macao, just walk around and you will still be amazed.
