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.

    They wear the latest fashions with the most up-to-date accessories(配饰). Yet these are girls in their teens or twenties but women in their sixties and seventies. A generation which would once only wear old-fashioned clothes is now favoring the same high street looks worn by those half their age.

    Professor Julia Twigg, a social policy expert , said ,“Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s .In the 1960s buying a coat for a woman was a serious matter . It was an expensive item that they would purchase only every three or four years — now you can pick one up at the supermarket whosever you wish to .Fashion is a lot cheaper and people felt tired of things more quickly . ”

    Fashion designer Angela Barnard ,who runs own fashion business in London ,said older women were much more affected celebrity(名流) style than in previous years .

    She said, “When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties ,they want to follow them . Older women are much more aware of celebrities .There's also the boom in TV programs showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties . When I started my business a fen years ago .my older customers wended to be very rich, but now they are what I would call ordinary women .My own mother is 61 and she wears the latest fashions in a way she would call ordinary women .My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago.”

    In our daily life, it is necessary to make small talk in some situations. It helps to fill time between people when it is very quiet. You may not feel like talking with someone else or you are very shy at the beginning, but it is sometimes thought to be not polite to say nothing.

    People use small talk almost every day. It usually takes place when you meet someone you don't know at all or someone you're not familiar with. For example, waiters and hairdressers often make small talk with their customers（顾客）. If you happen to be outside when the postman comes to your door, you might make small talk with him, too.

    Most often, small talk happens in places where people are waiting for something. For example, you might talk with another person who is waiting for the bus to arrive. People also make small talk in a doctor's waiting room, or when they are waiting in a line to buy something. At the office, people make small talk in lunch rooms, especially if there is a line-up. Mingling is often required（要求）among people who don't know each other very well at a party. That is to say, they are expected to walk around and talk with others.

    The most common time for small talk to happen is the first time you see or meet someone on a given day. For example, if you see a neighbor in the waiting room of the airport you might say hello and discuss the sports or weather. However, the next time you see each other you might just smile and say nothing. If there is very little noise, it might be the right time to start a pleasant conversation. If someone is reading a book at the bus stop, it is probably not a good idea to start a conversation. Another good time to make small talk is during a break in a meeting when there is nothing important going on. However, it is important to recognize the signal when the other person wants the conversation to stop.

    Last month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship!

    Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earth's gravity. It was so hard that we could not say anything to each other. Gradually the weight lessened and I was able to talk to him. "Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground." I asked. "We are too far from the earth now to feel its pull, " he explained, "so we feel as if there is no gravity at all. When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth's. " I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.

    When we got there, I wanted to explore immediately. "Come on," I said. "If you are right, my mass will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!" I laughed and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell over. "Oh dear," I cried, "walking does need a bit of practice now that gravity has changed." After a while I got the hang of it and we began to enjoy ourselves.

    If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(快闪族), which is a group of people who come together suddenly in a public place, do something unusual for a brief period of time, and then quickly break up. They are usually organized with the help of the Internet or other digital communication network. At a predetermined(预先决定的) time, they gather and perform some distractions(消遣) such as waving their hands and exchanging books. Then, they quickly break up before the police can arrive. Using mobile phones, the flash mob can change its location if the first one has been replaced for any reason.

    Bill Lasik, senior editor of Harper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob came together on June 3, 2003 —after the first attempt failed at Macy's department store. Lasik claimed that the activity was designed to make fun of hipsters(赶时髦的人), and call attention to the cultural atmosphere.

    Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and untrue, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mobs can serve as good political tools in any direction. They also have great economic potential, such as using flash mobs to advertise a product.

    The flash mob is now becoming more and more popular. People use it to do many things. For example, in 2009, Michael Jackson's fans took part in a flash mob to remember him. Hundreds of his fans gathered singing and dancing Michael's famous song “Beat It” together. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

    Scientists have found an unexpected use for virtual reality headsets (耳机). The devices (装置), widely used by computer gamers, show pictures that can be used to test the navigational (导航的) skills of people, who were thought to be at risk of dementia (痴呆). Those who do worse in the tests will be the ones more likely to develop Alzheimer's disease later in life, scientists now believe.

    The discovery that the loss of navigational skills was associated with Alzheimer's was made several years ago by Dennis Chan and his colleagues based at several centers in the UK. These studies used computers to test navigational tasks. But now scientists plan to take their tests to a new level with the use of the virtual reality headsets in which wearers are placed in man-made environments through which they must navigate.

    Around 300 people, aged between 40 and 60, will be arranged to participate in the study. Some will have a gene that puts them at risk of the condition or will come from a family with a history of Alzheimer's. Not all will certainly be affected by the disease, however. Chan's project aims to find out who will. Wearing the headsets, participants will be asked to navigate their way through a series of different environments and then remember the details.

    Researchers recently pointed out the significance of a tiny area of the brain known as the entorhinal cortex (an important memory center in the brain). It acts as a center in a widespread brain network that controls navigation. This now appears to be the first part of the brain that seems to be easily harmed by Alzheimer's.

    The goal of the work is to help people as they develop the disease. "So far, drug trials for Alzheimer's have been applied when people have already got dementia, by which time considerable damage to the brain has already occurred," Chan told the Obsenver. "If we can develop drugs and use them earlier, for example, before the disease has spread beyong the entorhinal cortex, then this would have the potential to prevent the dementia."
