Teenagers who spend hours in front 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.

    Social media and the mobile web have given rise to a strange phenomenon called the selfie(自拍). It refers to a picture of yourself, usually shared on any social networking website.

    {#blank#}1{#/blank#}Some selfies are extreme close-ups(特写镜头), and others show part of an arm held straight outward. A few of them even feature the subject standing in front of a bathroom mirror.

    Everyone takes selfies, but the younger crowd seems to be especially involved in the trend. Young people are relatively heavier digital users. They are interested in staying connected to their friends.{#blank#}2{#/blank#}

    There are also kinds of psychological factors driving people to take a selfie and upload it to a social networking site.{#blank#}3{#/blank#} A quick and easy way to attract other's attention is to get "likes" and comments from friends. Secondly, it's human nature to show off your own great achievements. When you feel good about yourself or look good, it's far too easy to take out your phone and document it all through one or several selfies.{#blank#}4{#/blank#}That's right. Sometimes people are bored at work, bored at school, bored at home and even bored on the toilet. Last but not least, social media is about being social! If that means uploading as many selfies as possible, then so be it. It's fun, and it's a cool way to sort of document your own life.

    Finally, there are things to be mindful of when you're posting. It's easy to think you're sharing a photo with a few people.{#blank#}5{#/blank#}So don't post anything online, selfie especially.

A. There are lots of selfie styles.

B. The rise of selfies has become universal.

C. Social media, to some extent, is the driving force of their selfie activity.

D. The desire to take, post and get "likes" on selfies goes back to a biological behavior.

E. But the whole world of social media is public and every individual can get access to it.

F. There are also people who will take selfies because they have nothing else better to do.

G. The leading factor is that people want to get attention from as many people as possible.

    A warm drink of milk before bed has long been the best choice for those wanting nights sleep. But now a study has found it really does help people nod off-if it is milked from a cow at night.

    Researchers have discovered that" night milk" contains more melatonin(褪黑激素) which has been proven to help people feel sleepy and reduce anxiety.

    The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

    Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

    Night milk quickened the start of sleep and caused the mice to sleep longer.

    While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

    Early studies have also showed that milk can be excellent for helping sleep because of containing Ca., which helps people to relax.

    Milk is also sugar-free and additive-free(不含添加物的) with experts advising skimmed (脱脂的) milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

    Whenever we talk about holidays, my mother teases my sister and me about how we “make out like robbers.” She is referring to the fact that we are half Jewish and half Indian, so we receive gifts on both the festivals of lights: Hanukkah and Diwali. Though my mother teases us, I do not mind getting two sets of gifts!

    Hanukkah is celebrated on the 25^th day of the Jewish month, which is usually sometime in December. On Hanukkah, like most Jewish families, we light a menorah and say a prayer each night. We also say a special prayer on the first night. After that, it is a tradition for my sister and me to do 'hot and cold' for our hidden Hanukkah gifts. When we walk towards the gift, our parents say 'hot' and when we walk further away, they say 'cold'. We each receive one present every night of Hanukkah. Another part I like about this holiday is seeing family members who we do not see often. My aunt usually stays for a few days, and we sometimes visit other relatives.

    Diwali is celebrated on the 13^th day of the dark fortnight of the month of Ashwin (October/November). To celebrate Diwali, my family does a pooja, or prayers, in honor of the goddess Lakshmi. Since she is the goddess of wealth and prosperity, the pooja includes washing silver coins in milk and water. In India, people decorate their houses with lamps, similar to the way you might light up your house for Christmas. My family just places a few candles outside. We also set off firecrackers, which is my favorite part. We often do this activity with friends to add to the excitement.

    Both holidays have different histories and stories. We celebrate them in different ways, yet they both have the same meaning. They both translate into Festival of Lights, and they both mean family and presents for me!

    Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.

    Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.

    It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes curry or rich pasta sauces, which may please their partner. Women still have the strongest long-term influence over the couple's diet and lifestyle, as they still have the traditional role of shopper and cook in most households.

    The report, by Newcastle University's Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.

    The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partner

    Women also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.

    Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.

    Report author and registered dietician Dr. Amelia Lake said, "The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration."

    Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder(ADHD)(注意力缺陷多动障碍)in the UK. A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19, 500 UK children born between 2000 and 2002 .The study was published in the Journal of Child Psychology and Psychiatry.

    Findings showed that more children with ADHD came from families below the poverty line than the UK population as a whole, with average family incomes for households whose study child was affected by ADHD at £324 per week, compared to £391 for those whose child was not. The study found the odds (机会)of parents in social housing having a child with ADHD was roughly three times greater than for those who owned their own homes.

    The team also found that the odds of younger mothers having a child with ADHD were significantly higher than for other mothers. Mothers with no qualifications were more than twice as likely to have a child with ADHD than those with degrees, and lone (孤独的)parents were more likely to have a child with ADHD diagnosis than households with two live-in parents.

    Information was gathered from surveys when the cohort children were nine months old, and at the ages of three, five, seven and eleven.

    Dr Ginny, of the University of Exeter Medical School, who led the study, said, "There is a genetic element to ADHD, but this study provides strong evidence that ADHD is also associated with a disadvantaged social and economic background. Some people believe that ADHD in children causes disadvantage to the economic situation of their family, but we found no evidence to support that theory. It's important to discover more about the causes of this disorder so that we can look towards prevention, and so that we can target treatment and support effectively. "
