It's normal to wake briefly during the night. {#blank#}1{#/blank#}But if you're waking up during the night and having trouble falling back asleep, the following tips may help.

    Stay out of your head. The key to getting back to sleep is continuing to prepare your body for sleep, so remain in bed in a relaxed position. Hard as it may be, try not to stress over the fact that you're awake , because that very stress and anxiety encourage your body to stay awake. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#} If you are finding it hard to fall back asleep, try a relaxation technique such as visualization, deep breathing, or meditation, which can be done without even getting out of bed. Remind yourself that although they're not a replacement for sleep, rest and relaxation still help refresh your body.

    Do a quiet, non-stimulating activity. If you've been awake for more than 15 minutes, try getting out of bed and doing a quiet, non-stimulating activity, such as reading a book. Keep the lights dim so as not to think that it's time to wake up. {#blank#}4{#/blank#} A light snack might help relax you, but be careful not to eat so much that your body begins to expect a meal at that time of the day.

    {#blank#}5{#/blank#} If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone worrying about it until the next day when you are fresh and it will be easier to resolve.

    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.

    Snoring(打鼾) is noisy breathing during sleep. It is a common problem among all ages and it influences about 90 million American adults. People most at risk are males and those who are overweight, but snoring is a problem of both genders, although it is possible that women do not present this complaint as frequently as men.

    Snoring is often the loud or harsh sound that can occur as you sleep. You snore when the flow of air makes the tissue in the back of your throat vibrate(颤动) as you breathe. The sound most often occurs as you breathe in air, and can come through the nose, mouth or both two organs. It can occur during any stage of sleep.

    About half of people snore at some point in their lives. Snoring is more common among men, though many women snore. It appears to run in families and becomes more common as you get older. About 40 percent of adult men and 24 percent of adult women are habitual snorers. Men become less likely to snore after the age of 70.

    Sleeping on your back may make you more likely to snore. You may snore when your throat or tongue muscles are relaxed. And substances(物质) that can relax these muscles may cause you to snore. These include alcohol, muscle relaxants and other medicine.

    Snoring can be a nuisance to your partner and anyone else nearby. You may even snore loudly enough to wake yourself up. Though, in many cases people do not realize that they snore. Snoring can also cause you to have a dry mouth when you wake up.

    Light snoring may not disrupt your overall sleep quality. Heavy snoring may be connected with a risk factor in the heart disease, stroke and many other health problems. So never take it lightly.

    To be sure, only children experienced some things differently from those with sisters and brothers. Many feel more pressure to succeed. They also tend to look only to their parents as role models in the absence of brothers and sisters.

    In India, 10-year-old Saviraj Sankpal founded a support group for the tiny minority(少数) of only children. Among other things, the group does volunteer work to fight against the false idea that they are not responsible. "People think we're treated too kindly and ruined," says Sankpal, a computer engineering student. "But I'd like to remind them how lonely it can get."

    Most only children, however, say they wish for sisters or brothers only when it comes to caring for aging, unhealthy parents. Britain's David Emerson, co-author of the book The Only Child, says that such a person has to make all the decisions alone. Emerson knows from experience. After his father died, he chose to move his elderly mother from their family home, where she was vulnerable (易受攻击的) to house breakers, to a new one with more safety. "The move was quite hard on her, and she might feel that I pushed her into it, "he says, "After all, I am left with that responsibility."

    In the future, more and more only children will probably face similar choices. With working mothers increasing, many families are finding they simply don't have the time, money or energy to have more than one child. As only children become common, perhaps the world will realize that the charge made against them is unfair.

    In 2001, British Prime Minister, Tony Blair said," We celebrate the diversity(多样性) in our country, get strength from the cultures and the races that go to make up Britain today."

    People from all cultures and races can be found in every corner of Britain and each person in his or her own way has contributed to making Britain the place it is today.

    If you walk down a street in Britain, especially in the bigger cities, you will usually see people with different hair, skin and eye colors. They may have white, brown or black skin and blonde, brown, black or red hair, with blue, black, brown or green eyes. Many of the people you will see will be British people but they all look different because the people of Britain are a mixed race.

    Britain is and has always been a mixed race society. Early in the British history they were invaded by Romans, Saxons, Vikings and Normans armies and later Africans were brought to Britain by force in the seventeenth and eighteenth centuries as slaves or servants. Over the years, thousands of people have been forced by persecution(迫害) or hunger to leave France, Ireland, Russia, and other countries, and have settled in Britain.

    About 8% of the population of Britain today are people from other cultures and races. That is 4.6 million people. According to a BBC report in September 2005, immigration (移民) made up more than half of Britain's population growth from 1991 to 2001.The Guardian newspaper reported in 2007 that the number of immigrants to the UK was 145,000 a year.

    People moving to Britain have brought their own cultures with them and try to keep them alive. An excellent example of this is the Notting Hill Carnival which celebrates the Caribbean culture and is now a very big part of British life today.

    Social media (社交媒体)is one of the fastest-growing industries in today's world. A study conducted by the US think tank (智囊团) Pew Research Center showed that 92 percent of teenagers go online daily.

    The wide spread of social media has changed nearly all parts of teenagers' lives.

    ●Changing relationships

    High school student Elly Cooper from Illinois said social media often reduces face-to-face communication.

    "It makes in-person relationships harder because people give attention to their phones instead of their boyfriends or girlfriends," Cooper said.

    There's also a greater possibility of things getting lost in translation over social media.

    "If half of your relationship is over social media, you don't really know how the other person is reacting," Sienna Schulte, a junior student from Illinois, said.

    Yet, some people believe social media has made it easier to start relationships with anyone from anywhere. Beth Kaplan from Illinois met her long-distance friend through social media. He currently lives in Scotland, but they're still able to frequently communicate with one another.

    "I can feel close to someone that I'm talking to via (通过) FaceTime," Kaplan said.

    ●Wanting to be "liked"

    The rise of social media has changed the way teenagers see themselves.

    The 19-year-old Essena O'Neill announced on the social networking service Instagram that she was quitting social media because it made her obsessed (痴迷) with appearing perfect online.

    Negative comments also can do great damage to a teenager's self-esteem (自尊).

    In particular, anonymous (匿名的) social media apps such as Yik Yak may provide opportunities for cyberbullying (网络欺凌).

    The app allows users within 5 miles (8 km) to create and add comments to everything. Teenagers who get negative comments on these sites can't help but feel hurt.

    ●Opening new doors

    However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube.

    "Social media can help people show themselves and their talents to the world in a way that was never possible before," Korsos said.

    But Korsos recognizes that social media has become a distraction.

    "Social media, though it helps people connect with their friends and stay updated, is not all necessary."
