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.

    During his first week as a new Atlanta police officer, Officer Che Milton answered a call for shoplift at the nearby Family Dollar store. When he arrived, Milton found a 12-year-old girl in tears over trying to steal a $2 pair of shoes. Crying, she told Milton that the shoes were supposed to surprise her 5-year-old sister.

    Milton, instead of arresting the girl, asked her to take him to her home instead. When he arrived, Milton's heart sank. He found a house nearly empty, with only a sofa and sheets on the floor instead of beds. There was no food in the kitchen and the kids were there. The girl's mother told the officer that her husband worked but didn't make much money and that she couldn't afford to do the same with several children to take care of and no daycare money to spare.

    Moved, the officer drove to a restaurant and bought four pizzas for them and he called the Division of Family and Children Services and asked if there was a social worker who could help.

    When the police department found out about Milton's trips, instead of punishing him, the department decided to share his story on Facebook and added that “not only is he here to enforce(实施) the law but also to go the extra mile and be a bigger part of the community he is policing.”

    Hundreds of citizens liked the post, asking how they could help. The department followed with posts including the six children's sizes and mother's clothing sizes. It also called for blanket and furniture donations. Visit the posts to learn how you can help and find more useful ways to donate your old things.

    Finding true love can be pretty tough for a lot of people, but a lady from a fairly well-known San Francisco advertising agency seems to think money helps. She is offering $10,000 to any of her friends who can introduce her to her Mr. Right. She wants to find her future husband through this way.

    The unnamed husband seeker who sent out the email had just finished reading the best-selling book named Lean In. It was 11 p. m. on a Sunday night and she realized this was the second self-help book she had read in the month. She was still single. Things were not looking fine, but there was hope for her still. If the book had taught her anything, it was that she needed to take a more positive role in finding love. After all, if she wanted to get a better job, she wouldn't just sit outside an employer's building and wait for someone to offer it to her, so why should finding a husband be any different? But instead of going out and meeting new people she decided to write an email to all her friends, offering to give them $10,000 on her wedding day if any of them managed to introduce her to her future husband.

    “I am writing you today because I've decided to make an aggressive action plan on finding the man that I get to hang out with forever,” the woman writes in her email. “Introducing me to my husband is just not high on your to-do list. But I think I have an idea that might change that…” You guessed it, and this is where she offers to reward her “closest friends” with cold hard cash.

    “I will personally give ten thousand dollars to the friend who introduces me to my husband.

    Here is how the program works:

    Step 1: You set me up on a date with a man.

    Step 2: I marry that man.

    Step 3: I give you $10,000 on my wedding day.

    I know you're thinking that this is nuts. Just plain crazy. 'You can find a husband without giving $10,000.' Well for starters, thank you! I'm happy.”

    The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.

    This suggested future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multi billion dollar Mars research programme. "Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael Meyer, NASA's senior scientist for astrobiology (太空生物学). "Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars."

    Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.

    But many experts are shocked by the idea. "We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet," said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.

    In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet's soil.

    But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. "Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native life forms, all the strange microbes that we hope to find buried in the soil," said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. "We cannot risk starting a global experiment that would wipe out the precious information we are looking for." she said, "This is just wrong."

    I first began experiencing depression (抑郁) at the age of 14 .At first depression would come and go, but later it became a continual part of my life.

    I was so strongly determined to find the way to overcome my depression that I tried everything from when I was in college, special teas, yoga (瑜伽), and advice given by doctors. However, I still felt I hadn't even come close to managing the problem.

    But one afternoon, I saw an article in a magazine that talked about how dogs were able to help people with depression. The next day, I decided to get a dog—a corgi (柯基犬).

    When I bought my little corgi, Buddy, home, I didn't realize how much he would change my life. One morning, I woke up with those familiar feelings again. I didn't want to get out of bed. I turned to pull the covers back over my head and give up. That's when I saw Buddy. He started jumping all over me, licking (舔) my face, letting me know that it was time to go outside. It was as if he were saying, "There's no time to be sad. The world is amazing!" And for the first time in my life, on a day when my depression were strong, I got out of bed. I put on my winter clothes and went for a walk in the snow with my new friend. I realized at that moment, walking down the street in winter, my life was changing. I really was a new person. This was my new beginning.

    It's been more than a year since that day, and I've never spent another morning unable to get out of bed. I've not cried myself to sleep or spent my days filled with fear and regret. Sure, I still have days when I feel sad or anxious. But with Buddy by my side, I've finally learned how to manage these feelings.
