The iPhone, the iPad: each of Apple's products sounds cool and has become a fashion. 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 2015. A lovely bear — popular in the US and UK — that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

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

    Most “i” products are aimed 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 interactive, 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 (轻便) .”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 “Microblog”, readers of BBC Magazines voted “i” as one of the top 20 words that have come to define the last ten years.

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

    The health of millions could be at risk because supplies of medicinal plants are being used up. These plants are used to make traditional medicine, including drugs to fight cancer. “The loss of medicinal plants is a quiet disaster,” says Sara Oldfield, secretary general of the NGO Botanic Gardens Conservation International.

    Most people worldwide rely on herbal (药草制的) medicines which are got mostly from wild plants. But some 15,000 of the 50,000 medicinal species are under threat of dying out, according to report from the international conservation group Plantlife. Shortages have been reported in China, India, Kenya, Nepal, Tanzania and Uganda.

    Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物种) and habitat destruction all contribute. Businessmen generally harvest medicinal plants, not caring about sustainability (可持续性),” the Plantlife report says, “damage is serious partly because they have no idea about it. but it is mainly because such collection is unorganized” Medicinal trees at risk include the Himalayan yew (紫衫) and the African cherry, which are used to treat some cancers.

    The solution, says the report's author, Alan Hamilton, is to encourage local people to protect these plants. Ten projects studied by Plantlife in India, Pakistan, China, Nepal, Uganda and Kenya showed this method can succeed. In Uganda, the project has kept a sustainable supply of low-cost cancer treatments, and in China a public-run medicinal plant project has been created for the first time.”

    “Improving health, earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants,” says Hamilton, “You have to pay attention to what people are interested in.”

    Ghillean Prance, the former director of the Royal Botanic Gardens at Kew in London, agrees that medicinal plants are in need of protection. “Not nearly enough is being done,” he told New Scientist. “We are destroying the very plants that are of most use to us.”

Dogs are man's best friends—they are very good for children's health. Researchers found that family pets helped to protect babies against breathing problems and infections (感染).

    A team from Kuopio University Hospital in Finland studied 397 babies born at their hospital between September 2012 and May 2015 for their first year. They found that babies who lived with a dog or a cat spent fewer weeks with ear infections, coughs or runny noses. They were also less likely to need antibiotics (抗生素) than babies in homes without a pet.

    Study author, Dr. Eija Bergroth, said dogs brought dirt and bacteria (细菌) into the home, which helped children's immune system (免疫系统) to be strong. This improved their defenses against bacteria.

    As part of the study, parents filled out weekly diaries starting when the children were nine weeks old, recording information on babies' health as well as their contact with cats and dogs. They recorded if they had fever, ear infections, coughs or running noses. They also put down whether they needed antibiotics.

    Based on those diaries, the researchers found that about a third of the children spent most of their first year with a pet dog and 24 percent in a home with a cat. And children with no dog contact at home were healthy for 65 percent of the time, compared to between 72 and 76 percent for those who did have a pet.

    The researchers also found that contact with dogs, more than cats, was tied to fewer weeks of sickness for babies.

    However, the researchers said they couldn't rule out the possibility that people who own dogs are less likely to get sick for another reason, not due to any protection offered by pets.

    A survey said the average Asian dad spent one minute a day with his children. I was shocked. I mean, a whole minute? Every day? Get real. Once a week maybe. The fact is, many Asian males are terrible at kid-related things. In fact, I am one of them.

    Child-rearing (养育) doesn't come naturally to guys. My mother knew the names of our teachers, best friends and crushes. My dad was only vaguely aware there were short people sharing the apartment. My mother bought healthy fresh food at the market every day. My dad would only go shopping when there was nothing in the fridge except a jar of butter. Then he'd buy beer. My mother always knew the right questions to ask our teachers. My dad would ask my English teacher if she could get us a discount on school fees. My mother served kid food to kids. My dad added chili sauce to everything, including our baby food.

    The truth is, mothers have superpowers. My son fell off a wall once and hurt himself all over. I demanded someone bring me a computer so I could google what to do. My wife ignored me and did some sort of chanting (咏诵) phrase such as" Mummy kiss it better," and cured 17 separate injuries in less than 15 seconds.

    Yes, mothers are incredible people, but they are not always correct. Yet honesty forces me to record the fact that mothers only know best 99.99 percent of the time. Here are some famous slip-ups.

    The mother of Bill Gates:" If you're going to drop out of college and hang out with your stupid friends, don't come running to me when you find yourself penniless." The mother of Albert Einstein:" When you grow up, you'll find that sitting around thinking about the nature of time and space won't pay the grocery bills." The mother of George W. Bush: "You'll never be like your dad, who became President of the United States and started his own war."

    Many animal and plant species have become extinct and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve the natural world they inhabit (居住) is now more important than ever.

    Dodo

    The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and the last one was killed in 1681.

    Rhinos

    The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most Rhinos now live in protected natural parks and reserves (保护区). Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers (偷猎者).

    The Giant Panda

    The future of the World Wildlife Fund's symbol is far from certain. As few as 1, 000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, the panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose (造成) one of the most serious threats to the animals continued existence.

    Whales

    The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world's oceans have been declared whale sanctuaries (保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

    Tigers

    The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5, 000 and 7, 000 and the Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers' bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.

    Making employees feel happy and healthy at work is good for many businesses. But it isn't always an easy thing. A research suggests that just 33% of the U. S. employees consider themselves fully engaged (投身于) at work, while 16% are actively disengaged, and 51% are just showing up.

    But there is an exception. When it comes to employee engagement, it seems that employees in small companies are doing better. According to the same research, the largest U.S. companies have the lowest levels of engagement, while companies with fewer than 25 employees have the highest. And in one recent report, 75 percent of small business workers surveyed said they were "very" or "extremely" satisfied with their role as a small company employee.

    Unlike big companies, small companies are often short of resources but the employees can get more surprises there. Small companies offer excellent career opportunities to their employees. The bosses often know their staff very well and understand their personal needs. Employees of small companies are more likely to receive free meals, paid leave, and they can even bring their pets to work.

    But of course, there're many other draws in small businesses. One of the top draws is flexible scheduling (弹性工时). Another is being able to really see the fruits of one's labor. Besides, non­cash award is also a big draw. This could be something small that reflects employees' interests and lifestyles.

    While a parental leave might lead to some financial problems, small companies may do something to improve it. "It may be impossible for a five­person team to be reduced to four for six months," writes Camilla Velasquez, head of HR management platform Justworks. "But it could be possible to allow new parents to take on reduced hours in a work­from­home environment." This kind of method has been realized in some small companies.
