Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. you can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

      Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they're in poorly lit places – and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

      Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it's time to repaint, go blue.

Don't forget the clock – or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

    As more and more people speak the global languages of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6，000～7，000 languages spoken around the world today will likely die out by the next century, according to the United Nations Educational, Scientific, and Cultural Organization (UNESCO).

    In an effort to prevent language loss, scholars from a number of organizations—UNESCO and National Geographic among them—have for many years been documenting dying languages and the cultures they reflect.

    Mark Turin, a scientist at the Macmillan Centre, Yale University, who specializes in the languages and  oral traditions of the Himalayas, is following in that tradition. His recently published book, AGrammarofThangmiwithanEthnolinguisticIntroductiontotheSpeakersandTheirCulture, grows out of his experience living, working, and raising a family in a village in Nepal.

    Documenting the Thangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayan reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.

    At the University of Cambridge Turin discovered a wealth of important materials—including photographs, films, tape recordings, and field notes—which had remained unstudied and were badly in need of care and protection.

    Now, through the two organizations that he has founded —the Digital Himalaya Project and the World Oral Literature Project—Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to scholars but to the younger generations of communities from whom the materials were originally collected. Thanks to digital technology and the widely available Internet, Turin notes, the endangered languages can be saved and reconnected with speech communities.

    Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father's wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.

     “Dad will be really mad if he finds out you've been playing with his new computer” Jason said, “He told us not  to touch it.”

     “He won't find out,” Mark said, “I'll just have a quick look and shut it down.”

    Mark had been scolded before for touching his father's equipment. But his curiosity was difficult to control and this new computer really puzzled him.

It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It's an experimental model,” his father had explained, so don't touch it under any circumstances.” But his father's warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”

     “Yes!” Mark cried excitedly, “It's a computer game. I knew it! Dad's only been pretending to work. He's really been playing games instead!” A new message appeared on the screen:

“ENTER NAMES

VOYAGE 1

VOYAGE 2

    Mark's finger flew across the keyboard as he typed in both of their names.

“INPUT ACCEPTED.

START TRANSPORT PROGRAM.

AUTO-RETRIEVE INITIATED( 自动回收程序已启动).”

    The screen turn even brighter and a noise suddenly rose in volume.

     “I think we'd better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒)，until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed：

“TRANSPORT SUCCESSFUL．

DESTINATION:  MARS.

RETRIEVE DATE:  2025

    "Are you going to Seattle?" an anxious-looking woman asked a female traveler at the Amtrak Airport in Sacramento. "No, I'm going to Eugene," the traveler replied. "Oh, I was hoping you could watch out for my daughter, she's never been on a plane before."

    Now, as I am quite a seasoned plane traveler, I know that seats and cars are supplied by destination（目的地）. So I came up to the woman and her frightened-looking daughter, telling them that her daughter could sit with me and that I would take care of her during the journey.

    The plane had arrived 25 minutes late, and people walked in line to get their seats. The conductor wanted to know if there were people traveling together, so I went to the front of the line with the girl and we were arranged to sit next to each other. Once on board, I showed her where to put her package, and took her to the bathroom area. Then we settled down to sleep. In the morning, I showed her the dining room and bought her a drink. She became comfortable enough to do what most 15-year-olds do: talk and text on her mobile phone.

    All through the trip, I made sure she picked up her ID, which had fallen out of her backpack, some money, which had fallen into the crack （缝隙） of the reclining seat, and continuously kept an eye on her. I hope someone takes her under their wing when she flies back to Sacramento.

    I do hope that kindness will spread around the world through these ways. We're conditioned to think that our lives go on with great moments. But great moments often catch us unaware, beautifully wrapped（包裹）in what others may consider a small one.

    About six years ago I was going through a tough time, trying to work two jobs to afford my rent. On a cold Sunday morning, I went to GameStop-a video game retailer（零售商）, to cancel the game I'd booked. A woman in a car parked outside called me when I exited the store. Though it was in broad daylight, I was shy about it and kept some distance when I walked over. She said she couldn't walk and requested me to purchase a Kinect, a popular game, for her as her son's Christmas gift. Because of her leg disease it was painful for her to move around. She called ahead but the employee（雇员）wasn't willing to help. She gave me about $ 100 in cash and her credit card.

    I walked back in and bought the Kinect. Then it occurred to me that this woman, a complete stranger, trusted me. What was it that stopped me from lying about the payment method and just pocket her cash? She couldn't know I wasn't a cheat; and how could she possibly believe in someone so much?

    I handed her the cash back, explaining I had to pay with her card-it was above $ 100 at the time, and handed over the game and her credit card. "This is what my son's been longing for. Thank you! By the way, just from glancing at you, I know you are the one who will be a friend to someone in need. You have a face of an angel!" she said. She gave me $ 10 and refused to take it back. Then she drove away.

    She had no idea how much of a difference even $ 10 made. I was able to buy a few cheap groceries for the week and it really made a hard time in my life a little better. She may think I helped her; however, I truly feel like the one who was being gifted something amazing.

    Large gatherings such as weddings and conferences can be socially stressful. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, .but privacy experts recommend going on with caution.

    The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. "It breaks down these social barriers we all have when meting somebody," says Bany Sandrew, who Created the app and tested it at an event attended by about 10000 people.

    After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies(自拍) and sign in via social median At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual, displays the person's name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users' data after an event.

    Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app's creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that "there may be unintended consequences down the road with that information being used in another context that might come back to bite you."

    The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or "face blindness", a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone's face, from either the smartphone's camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.
