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--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 such as e-mail and e-commerce(电子商务) first came into use.

    Most “I” products are targeted at(针对) 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(定义),” 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 “blog”, readers of BBC Magazines voted “I” as one of the top 20 words that have come to define the last decade(十年).

    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. However, as we entered the new century, the fashion disappeared.

How to improve your vocabulary

    Vocabulary is a key part of learning a new language. {#blank#}1{#/blank#}  Maybe you can't learn a hundred new words a day, but you can learn one or two a day, totaling thousands of new words over the years. Here are some tips for building up your vocabulary.

    Make a plan to learn new words. If you want to improve your vocabulary more quickly, you have to make at least a small promise. {#blank#}2{#/blank#}

Make you vocabulary practical（实用的）. {#blank#}3{#/blank#} For example, learn more of your trade language—- the words that are commonly used in your business or hobby or vocation(职业). Find better, fresher, clearer words to express what your friends are talking about.

    {#blank#}4{#/blank#} As you read, if you come across a new word that you don't understand. Don't miss it. Take the time to look it up in a dictionary. Write it down and use it later.

    When you learn a word, use it immediately and frequently. Put your new word into conversation with as many different people as you can. {#blank#}5{#/blank#} Use it in sentences. Write it on a card and practice it while waiting for red lights.

A. Repeat it to yourself.

B. They're highly reusable

C. Start learning where you are.

D. Decide to learn one new word every day or two.

E. When you're writing something, use a dictionary frequently

F. Start by learning the words that can express what's most important to you.

G. The more you read, the more words you'll see, and the more you'll understand.

    Night owls, people who stay up late and struggle to get out of bed in the morning, are more likely to die sooner than morning larks, the first study into their death rates has found.

    New research by the University of Surrey and Northwestern University in the US found that people who naturally stay up late were 10 per cent more likely to die within the six-and-a-half-year study period compared to those who preferred the morning.

    Researchers say that the ongoing stress of operating in a traditional 9-5 society was having a huge effect on millions of people and could be shortening their lives.

    “This is a public health issue that can no longer be ignored,” said Malcolm von Schantz, a professor of chronobiology at the University of Surrey. “We should discuss allowing evening types to start and finish work later, where practical. And we need more research about how we can help evening types deal with the higher effort of keeping their body clock in line with sun time”.

    The research involved nearly 500,000 Brits aged between 38 and 73 and found that around nine per cent considered themselves evening people, while 27 per cent identified as morning types.

    In the new study, Scientists found owls had higher rates of diabetes, psychological disorders and neurological disorders. But the team has previously shown that whether someone is an owl or a lark is half genetic and half environment, meaning there may be ways to keep body clock issues under control.

    The team recommends that night owls can help themselves by trying to become exposed to light early in the morning and not at night. Keeping regular bedtimes, maintaining a healthy lifestyle and trying to do tasks earlier in the day can help to reset body rhythms.

    The study was published in the journal Chronobiology International.

    Chinese people are, quite rightly, proud of their food. However, when foreigners like Britons and Americans think of Chinese food, their impression of it is different to what you might think.

    Growing up in the UK, the Chinese food I was used to eating was food I now recognize as being from Guangdong. For example, a typical dish I would order would be pork in sweet and sour sauce, probably with some rice and spring rolls on the side. This is the type of food we generally eat because most Chinese immigrants(移民) to the UK have come from Guangdong. You can tell, because when most British people try to copy the sound of Chinese, they actually copy the sound of Guangdong people—hearing the real Putonghua is sometimes a shock to British people who have grown up thinking it sounds completely different!

    British attitudes to Chinese food may be changing, though. Chinese-American chef Ken Hom has been on British TV for 30 years, and he told BBC Food: "Chinese food at the beginning of the 80s (in the UK) was sweet and sour pork, mainly. Most Brits had the unchangeable view of Chinese food. Now you are seeing more local Chinese food from Sichuan, Hunan and other areas of China. It is no longer just Guangdong food." Similarly, to most Americans, Chinese food doesn't go too far past orange chicken and fortune cookies, but more Chinese local dishes are becoming successful, especially in big cities like New York.

    Attitudes have not quite changed completely, though. Many foreigners who live in China will be familiar with this question from a relative back at home: "Have they given you dog yet?" Yes, perhaps because people still know too little about Chinese culture, many people believe that Chinese people love to eat dog meat. And of course, some people do eat dogs, which to Americans is like "eating a member of one's family" according to Vision Times. Also, Chinese people eat many other things people in the West do not—chicken claws, duck heads and some animals' organs.

    But what do foreigners think when they come to China and taste real Chinese food? You'll be glad to know that in my experience, the impressions have been very good.

    The full moon climbs over the eastern horizon (地平线) and hangs like a huge orange globe in the sky. A few hours later, the moon is overhead but seems to have changed. The huge orange globe has become a small silver disk. What has happened? Why has the orange color disappeared? Why does the moon seem so much smaller and farther away now that it is overhead?

    The moon appears orange on the horizon because we view it through the dust of the atmosphere. The overhead moon does not really shrink (缩小) as it moves away from the horizon. Our eyes inform us that the overhead moon is farther away. But in this position the moon is actually closer to our eyes than when it is near the horizon.

    The change in size is a trick our eyes and minds play on us. When the moon is low in the sky, we can compare its size with familiar objects. It is easy to see that the moon is much larger than trees or buildings, for example. When the moon is high in the sky, however, it is hard to compare it with objects on earth. Compared to the vastness of the sky, the moon seems small.

    There is another reason why the moon seems to shrink. We are used to staring at objects straight ahead of us. When an object is difficult to see, our eyes have to try to focus on it. When we move our heads back to look up, we will try hard again. Looking at something from an unaccustomed position can fool you into believing an object is smaller or farther away than it is. However, scientists do not yet understand completely why the moon seems to shrink as it rises in the sky.
