You never played the video dance game? Now such games are used to help lose weight!

    Like many other teenage boys, Jones loves sports. But at 5 feet, 175 pounds, he found his weight in trouble. His doctor wanted him to lose 50 pounds so that he may be a good football game player by the end of the summer.

    Jones chose the popular Dance Revolution video game at home to increase his activity. He had lost about 10 pounds by changing his diet. Now, after two weeks' playing the game, he has lost another 10!

    A health study is being done by an insurance company. The company hopes that the game will lead to better health and lower costs. “Obesity claims last year cost us $ 77 million. We have to cut those costs,” said a member of the insurance group. The company provides a game console (游戏主机), a dance mat and software for the six-month, $ 60,000 study.

    The study is more than a commercial thing of an insurance company. It is widely supported by physical education and health professionals.

    In West Virginia, 43% of the nearly 6,000 children examined for heart disease risk were considered over-weighted; more than 25% were too fat. “We are in a crisis of childhood obesity not only in West Virginia but in America,” said a researcher.

    Researchers are now looking at the potential for improving effects by using the game. A teacher in West Virginia has been using the video games in her classes since last fall. She reported that the game does improve heart health as well as eye-hand coordination (协调能力), and her students take the video game as a great alternative to jumping rope or ball games.

    The US Education Department is putting the game in 20 schools to control childhood obesity. Well, are you going to try such to dance away your extra weight?

    Love it or hate it, there is no escape from Internet slang(俚语).

    This is especially true among young people in some English-speaking countries such as Australia, the UK and the US. These days, if they haven't caught up with the latest popular Internet slang, chances are that they often feel behind the times.

    Take these posts by The Washington Post for example: “David Bowie dying is totes tradge” and “When Cookie hugged Jamal, it made me totes emosh. ”

    What on earth do these mean? Well, “totes” is a short form of the adverb “totally”. Likewise, “tradge” means “tragic” and “emosh” means “emotional”.

    It seems that, for millennials (those born between the early 1980s and late 1990s), typing in this abbreviated form is not only time-saving but also in.

    Many millennial slang words are formed by what linguists(语言学家) call the practice of  “totesing” —the systematic abbreviation of words, according to a recent article in The Washington Post.

    Some people think that millennial slang affects the English language negatively. However, Melbourne University linguist Rosey Billington doesn't agree.

     “When you are able to use language in a creative way, you show you are linguistically knowledgeable because you know the language rules well enough to use words in a different way.” Billington told News.com.au.

    Her view is supported by two linguists, Lauren Spradlin and Taylor Jones, from the City University of New York and the University of Pennsylvania respectively. The two believe that totes-speak is a highly-organized system that can only be used by speakers who have mastered English pronunciation.

    The ability to break apart syllables(音节) and mix different sounds together is key. “Totesing is about sounds, and it follows the sometimes-complex sound system of English,” Jones told The Washington Post. “Totesing is considered random by some people, but it's not true. Instead, it has strict rules to follow. You need to be very fluent in the English language to be able to understand totes-speak. ”

    Italian Joseph Caspar Mezzofanti was said to have spoken more than 38 languages fluently at the time of his death in 1849, a skill that would have been useful in today's globalized economy. Unfortunately, when it comes to the high school Spanish lesson in the decades, most people nowadays have remembered that there is nothing more complex than "Donde esta la biblioteca". So we set out to uncover what's involved in learning a foreign language and which methods work best.

    Some advertisements say that some language learners believe they're just a 15-minute audio tape away from becoming UN interpreters. But experts say these get-fluent-fast programs are a complete sham." Actually, there is hardly a shortcut that can do that," says Dekeyser, a professor of second language acquisition at the University of Maryland." The only way to learn a language is to make quite a bit of effort on a daily basis."

    Many experts agree that the ideal learning method for language learners really depends on the individual." Find the method that works for you and stick with it," says Simcott, a polyglot who has professionally worked in over 14 languages at once for the British Foreign Service." If audio works for you, do audio. If you like taking classes, do classes. But remember to keep practicing every day."

    However, not all people are created equal. Some may have talent for language learning, but it doesn't mean they can passively await fluency. "Practice is an effective learning method," says Davidson." The more time that you spend during the day speaking your second language, the better at it you're going to be."

    Learning from multiple people is also a good way, especially when you are attempting to cultivate a native accent. "When you are exposed to a lot of people, you get a much better sense of what the sound of a word is supposed to be," says Davidson. "You avoid exposing yourself to what could be features in one individual's speech patterns."

    Play is vital in every child's development, and for toddlers(蹒跚学步的小孩) the benefits of play especially come to life when they can connect with parents during playtime. To raise awareness and help parents create the time and attention span needed, LEGO and DUPLO launches a "Do not disturb playtime '' campaign. 21 days is what it takes on average to break a habit, so for 21 days the LEGO DUPLO team will not post on social media during "toddler playtime", defined as 5am-8pm.

    With social media being an integrated(不可或缺的) part and creative inspiration to modern family life, it is no surprise that researchers call out digital behavior as a concerning obstacle to quality playtime.

    "While we are hooked on our cell phones, we should think about turning them off when interacting with our young children. Kids learn so much from us and we don't want to get in the way of that. Take language learning for example. When nurturing caregivers talk to their children about what they are interested in, it helps them learn new words and new ways to express themselves. Our research shows that the use of a cell phone in a conversation between parent and child disturbs that child's word learning." advises Roberta Golinkoff, PhD: Professor, University of Delaware.

    Our research shows that parents today understand their significant role in ensuring their kids grow up to be happy, well-rounded, and equipped for the future. At the same time, many worry about not spending enough time with their toddlers. LEGO DUPLO wants to inspire parents to make the small moments memorable.

    "We know parents today feel more time-starved than ever before. Many feel guilty over not spending enough time with their little ones. Through the 'Do not disturb playtime' campaign, we hope to re-assure parents that it's not so much of the amount of time they spend with their kids, but the small meaningful moments they create during play", said Steffen Jensen, LEGO Group Senior Marketing Director.

    After photographer Monni Must's daughter Miya died, the sad mother adopted her black dog, Billy Bean. As Billy became increasingly weak, the thought of its dying was just more than Must could handle. So she decided to clone the dog. “I feared everyone was going to forget Miya," she said, "and my other daughters thought I had completely lost my mind."

    Billy's cells were shipped to ViaGen Pets, a Texas company that provides the cloning service. With more than $50,000, Must picked up a new puppy. "The dog has a real soul and is everything my daughter was—fun, social and kind," she said. "I feel that I still have that touchable connection and not just a spiritual connection.”

    Cloning animals is hardly new. But the recent news that singer Barbra Streisand had cloned her dog grabbed international headlines. People for the Ethical Treatment of Animals(PETA) president Ingrid Newkirk issued a statement saying she would love to talk her out of cloning, noting that millions of wonderful dogs are getting old in animal shelters every year or dying in terrifying ways when abandoned.

    Normally, a doctor takes a tissue biopsy(组织活检), a piece of skin and muscle about the size of a pencil eraser, from the dog. The next step is to take an egg cell from a donor dog, remove the egg's nucleus, and insert DNA from the pet to be cloned. When an embryo(胚胎)develops, it is transplanted in the body of a mother dog.

    In the basic cloning procedure, scientists take an entire adult cell and put it into an egg that's been relieved of its own DNA. The resulting embryo is a clone. However, in many animals, only one in 100 cloned embryos ever leads to a live birth. Some embryos die in the IVF dish or in the mothers bodies. Of those that are born, a few suffer from abnormalities and quickly die. Besides, pet cloning doesn't mean copying everything of your beloved pets.

    Teenagers who spend hours in front of the television may have a poorer diet as young adults.

    A study, which included nearly 1, 400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers (同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake (吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

    As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.
