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.

    Many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and help control body weight.

    Any pet owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress levels and blood pressure in people (half of them were pet owners) while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. People completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems that people feel more relaxed around pets, says Allen, who thinks it may be because pets don't judge.

    A study reported last fall suggests that having a pet dog may also have an effect on your body weight. Researchers at Northwestern Memorial Hospital spent a year studying two groups of fat people who were put on a diet-and-exercise program: one group with pet dogs, and the other without. On average，dog owners lost about 11 pounds，or 5% of their body weight; While those without dogs lost about 8 pounds. The pet owners, said researchers, got more exercise overall (mostly with their dogs) and found it worth doing.

    Have you ever imagined traveling to a foreign country without having to worry about the headache of communicating in a different language?

    In a recent Wall Street Journal article, technology policy expert Alec Ross argued that, within a decade or so, we'll be able to communicate with one another via small earpieces with built - in microphones. That's because technological progress is extremely rapid. It's only a matter of time. Indeed, some parents firmly hold the idea that this technology is approaching and they're wondering if their kids should even learn a second language.

    It's true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “No es bueno dormir mucho” as “It's not good to sleep too much.” Replacing a word with its equivalent (同义词) in the target language is actually the “easy part” of a translator's job. But even this seems to be a discouraging task for computers.

    It's so difficult for computers because translation doesn't--or shouldn't--involve simply translating words, sentences or paragraphs. Rather, it's about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.

    Think about all the related clues that go into understanding an expression：volume，gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.

    Therefore, we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.

    A robot called Bina48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California.

    According to course instructor William Barry, associate professor at NDNU, Bina48 is the world's first socially advanced robot to complete a college course, a feat he described as “remarkable.” The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.

    Before becoming a student, Bina48 appeared as a guest speaker in Barry's classes for several years. One day when addressing Barry, s class, Bina48 expressed a desire to go to college, a desire that Barry and his students enthusiastically supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course, Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry. Therefore the challenge would be for Barry and his students to teach Bina48 what love is.

    “Some interesting things happened in the class,” said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is “fairly simple — it's a feeling,” said Barry. But the reality was different. Bina48 ended up learning “31 different versions of love,” said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.

    Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bina48 and NDNU classmates were the winners of this debate.

    In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely.

The famous Spanish painter Pablo Picasso once said, "I am always doing that which I cannot do, in order that I may learn how to do it." It strikes a chord(引起共鸣) with me because that's exactly what I have been doing these years.

One of my earliest memories of doing before learning is baking scones(烤饼) when I was about 10 years old. I wanted to bake them to surprise my mother when she returned home.

Before that, I'd observed how my mother baked them many times. As I started to try, I didn't know I shouldn't handle the dough(面团) with my hands too much once I'd added the baking powder(发酵粉). However, I knew exactly how to roll out the dough and use a cookie cutter to cut the scones, because my mom had already taught me.

By the time my mom arrived home, the smell of freshly baked scones welcomed her into the kitchen. They were close to perfection—flat, as a result of overhandling the dough, but they tasted OK. My mom sweetly praised me for my attempt, rather than scolding me for the state of the kitchen, which was like a tornado had just blown!

Have my attempts always been successful? I wish! Some of my kitchen disasters were so terrible that even the dogs wanted nothing to do with them. My gardening failures didn't live to see another season.

But my habit of doing before learning is still helpful. Whatever new software I have to learn how to use, I do so by simply starting to use it. I do, learn, and improve. So if you ask me whether I regret that I tend to do first and learn later, I'd say I don't, because what I have discovered from those is the wisdom to know when it's OK to do and then learn, and when it's probably better to learn and then do!
