Many blind people use guide dogs to help them get safely from place to place and to warn them of danger. But what can blind people do if they are allergic(过敏的) to dogs or just don't like them? For these people, they can turn to the Guide Horse Foundation.

    Janet and Don Burleson founded(成立) the organization in 1999. They began training miniature horses to help guide blind people. Miniature horses look just like common horses, only much smaller. They are generally less than 34 inches tall.

    Cuddles was the foundation's first guide horse in full service. She became 45-year-old Dan Shaw's helper. Shaw has an eye disease and his sight is very poor. One night, while filling out a form to get a guide dog, Shaw heard a news story on TV about people training horses to guide the blind. Shaw loves horses and wanted a guide animal that would live a long time. So he applied(申请)，and a year later, Cuddles and Shaw began training as a team.

    On a trip to New York, Cuddles helped Shaw safely visit many places of interest .They even traveled on a boat and on the subway system.

    Shaw says that he is very lucky to have Cuddles. He believes that Cuddles has changed his life for the better by giving him the chance to do things himself and making him feel much more confident about himself.

    The iPhone the iPad: each of Apple's products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i”—and many other brands are following suit. The BBC's iPlayer—which allows Web users to watch TV programs on the Internet—used the title in 2008. A lovely bear—popular in the US and UK一that plays music and vide is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was stated last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use.

    Most “i” products are targeted at young people and considering the major readers of Independent's “i”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i” Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i”works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or intcractive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition,” he says.

    “However, thanks to Apple, the term is now connected with portability.” adds Thorne.

    Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with“Google” and “blog”, readers of BBC Magazines voted“i”as one of the top 20 words that have come to define the last decade.

    But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. How ever, as we entered the new century, the fashion disappeared.

    Binge-watching (刷剧) is when a person watches more than one episode of a TV show one after another. With developments in the speed and connectivity of the Internet, increases in technology and the rise of on-demand entertainment companies, people can now watch their favorite shows directly on the Internet at their convenience.

    This behavior is nothing new. In fact, “binge-watching” has been officially listed in dictionaries since 2015. The entertainment companies recognize this behavior and many take steps to encourage it. Often, instead of releasing each episode on a week-by-week basis, an entire series will become available at the same time. Once the episode finishes, many platforms will display pop-ups with “you might like” suggestions, or will automatically play the next episode.

    However, this wonderful gift may in fact be poisonous. Recent research from British media Ofcom suggests that this behavior may have become a hindrance (障碍). Out of the more than half of British adults who watch more than one episode of a show in a row, almost a third have admitted missing sleep or becoming tired as a result; and one quarter have failed to do their household chores. Next well be missing work!

    Bingeing has other connections—binge eating, binge drinking and binge smoking, all of which are often associated with compulsive (强迫性的) behavior, a lack of control and possible route to addiction. Lindsey Fussell, consumer group director at Ofcom, said, “The days of waiting a week for the next episode are largely gone, with people finding it hard to resist watching multiple episodes around the house or on the move.” If people find binge-watching hard to resist, coupled with the fact that it has shown to lead to negligence (疏忽) in many, are we witnessing the birth of a new type of addiction?

    The large amount of information and entertainment that television and online media can bring us is, many would say, a good thing. It offers us opportunities to better understand the world we live in, educate ourselves and enjoy much needed downtime. However, like any behavior done to an extreme degree, it can become dangerous. And when the activity begins to bleed into other areas, causing us to stop functioning-then it becomes a problem. So, what's the answer? Neither a tiny amount, nor too much. After all, as the old proverb says, a little of what you fancy does you good.

    Developed by researchers and designers specializing in typography(印刷术)and behavioral science, Sans Forgetica is a new font(字体)designed to help readers better remember the information they read by forcing them to spend a bit more time on each word.

    The design of Sans Forgetica is based on a font called Albion, but with substantial  modifications(修改)to reduce familiarity and attain its goal of engaging the brain more and helping the reader retain(保留) more information. It was developed by scientists at RMIT University in Melbourne, Australia, who believe it could help students studying for exams.

    “We believe this is the first time that specific principles of design theory have been combined with specific principles of psychology theory in order to create a font, ”Behavioral economist Jo Peryman told DW.

    If fonts are too familiar, readers often glance over them without their brain creating may  memories of what was read. At the same time, if a font is too outlandish, the brain has to struggle too much to decipher(破译)it while neglecting the retention of information. According to its developers, “Sans Forgetica lies at a sweet spot where just enough obstacle has been added to create that memory retention.” Its modifications force readers to spend more time, but not too much time, reading each word, allowing the brain to engage in deeper cognitive processing.

    So does Sans Forgetica actually work? Does it help readers better remember the information they read? So far, studies have shown that it can make a difference, although not a significant one.

    One experiment had 96 participants recall word pairs presented in three different fonts. They remembered 69 percent of the word pairs written in Sans Forgetica, compared to 61 percent for the other fonts. In a different experiment, 303 students took a mock(模拟)multiple-choice exam, and whenever the text was presented in Sans Forgetica, they remembered 57 percent of the text, compared to only 50 percent of the surrounding text written in Arial font.

    So Sans Forgetica won't give you the memory of an elephant, but if you're the kind of person who believes every little bit helps, it might be worth a try.

    Measles (麻疹) is only found in human beings. There is a highly effective and safe vaccine (疫苗) for the disease. So, in theory, measles could be destroyed.

    Yet the number of measles cases is on the rise.

    The World Health Organization (WHO) reports that, in the first three months of 2019, the number of cases is three times higher than it was last year. Africa alone has had a 700 percent increase compared to last year.

    The Democratic Republic of Congo reported 67,000 measles cases and 901 measles-related deaths in 2018. This year, WHO officials have noted more than 40, 000 suspected measles cases in the country. That number includes 284 measles-related deaths in the first weeks of 2019. Between September 2018 and February 2019, Madagascar reported over 67, 000 measles cases, including 828 deaths.

    Dr. Fauci, who directs the National Institute of Allergy and Infectious Disease in the USA, said that one in 10 children who get infected with measles will get an ear infection that could cause deafness. One in 20 would get pneumonia. One in a thousand would get brain swelling, and one to three per thousand would die. To say that measles is a slight disease is completely incorrect.

    Walter Orenstein is with the Emory University Vaccine Center in Atlanta, Georgia. He has spent his life working to end measles. Orenstein says possible effects of the disease are worse in poor countries. In those countries children are already at greater risk. They may be malnourished (营养不良的). They may have damaged immune systems. They may be underweight and may have no access to health care so measles is a big killer, he said.

    You have a 90 percent chance of getting measles if you have not been vaccinated and you come in contact with someone who has it. Dr. Rebecca Martin is the Director of the Center for Global Health at the U.S. Centers for Disease Control. She is working to remove measles from Africa completely. It is very infectious. It will find nearly everybody who is not protected against measles, Martin said.

    Health experts advise patients to get two treatments of the measles vaccine. U.S. health officials say educating parents about both the disease and the vaccine is an important step in stopping the spread. Equally important is making vaccination a top goal of health systems worldwide.

    Josh Katz works at the New York Times. His common job is to use information to tell interesting stories. In December 2013, Katz built a quiz on the Times website. It asked people about the words they used to describe things and events. It also asked how they pronounced common words. The quiz then used people's answers to decide where in the United States they were from.

    The quiz got more than 350, 000 results. Katz turned the results into a book. In Speaking American, he studies regional differences in how Americans talk.

"A lot of people's language shows who they are and where they are from, in a very personal way", Katz said.

Katz says people are often surprised to learn that the way they talk can show where they grew up. Most Americans don't realize they use regionalisms — or words and phrases specific to a particular part of the country. But just about everyone does. Almost every major U.S. city has a few unique terms. For example, in Philadelphia, Pennsylvania, the night before Halloween is known as Mischief Night. Anyone who calls it that is likely to be connected to the city.

    Katz himself was surprised by how many common words are regional. "There are a lot of words I use that I just thought were standard words," he says. "Then I found out some of these words were actually a product of my upbringing."

    For example, he says, "I thought everyone said 'sneakers' (运动鞋) and not 'tennis shoes'." But it turns out "sneakers" is connected mostly to the Northeast. That's where Katz is from.

    Some scholars think that language in the U.S. is growing more homogeneous (同类的). But Katz disagrees. "These regional differences are here to stay." he says.

    Not only are people still using common regionalisms, but there are new ones appearing all the time, according to Katz. There's no way to predict how language will change in the future. But Katz sees more changes coming. "The only sure thing about language is that it's going to keep moving." he says.
