    Save your pocket money.

    If you're going to relax a few times over the season, concentrate on foods that are special or unique to this time of year not the ones you can get year﹣round to avoid holiday weight gain, says Gary Foster, PhD, chief scientific officer for Weight Watchers. That means letting yourself enjoy a piece of pumpkin pie on Thanksgiving,{#blank#}2{#/blank#}The seasonal focus means when the holidays are past, the temptations will go with them and you can return to healthy eating.

    Wait to enjoy.

    "We recommend you delay your drink until you have food in your stomach," says Elizabeth Politti, RD, nutrition director for the Duke Diet and Fitness Center. She explains that food can help delay the absorption of alcohol. "Set some limits for yourself about alcohol such as that you won't have more than one or two drinks."  {#blank#}3{#/blank#}If one glass of wine makes you completely lose your eating inhibitions（抑制）,maybe it's better to hold in the face of food temptation.

    Are you afraid of going to the dentist(牙医)? If so, you're not alone.

    These fears could just be in our heads, however. According to a recent survey by Martin Tickle, a professor at the University of Manchester in the UK, the pain isn't felt most of the time in dental surgeries(牙科手术). In fact, among the 451 interviewed patients, 75％reported no pain at all during their visits, including situations when they had their teeth pulled out.

    Could it be the sound of the drill(钻头)then?

    "I found that the sound of drilling can evoke deep worry in dental patients. Actually they don't have any pain, "Hiroyuki Karibe, a scientist at Nippon Dental University in Tokyo, told The Guardian.

    To find the reason why a drill might bring on a racing heart, Karibe divided the volunteers into low-fear and high-fear groups based on how much they feared a trip to the dentist. Volunteers were played the sound of a drill while their brain activities were watched by a machine.

    What Karibe found in the low-fear group was increased activity in the areas of the brain relative to auditory processing(听觉处理), which means, for these people, the sound of dental drills is no different from other sounds.

    In the high-fear group, however, the brain area that was activated(激活)was different. It was the area that carries out a number of duties, including learning, feelings and, most importantly, memory. This means that these volunteers not only heard the sound, but they remembered it—they made connections between the sound of a drill and the worry it produced in the past, causing their worry to return.

    Understanding how brains reply to the sounds of dentists' drills could help scientists find ways to make patients more relaxed, according to Karibe, because patients who worry about going to the dentist might keep putting off their visits. But the best way is to keep your teeth healthy.

    When men and women take personality tests, some of the old Mars-Venus stereotypes(定式)keep reappearing. On average, women are more cooperative, kind, cautious and emotionally enthusiastic. Men tend to be more competitive, confident, rude and emotionally flat. Clear differences appear in early childhood and never disappear.

    What's not clear is the origin of these differences. Evolutionary psychologists think that these are natural features from ancient hunters and gatherers. Another school of psychologists argues that both sexes' personalities have been shaped by traditional social roles, and that personality differences will shrink as women spend less time taking care of children and more time in jobs outside the home.

    To test these hypotheses(假设), a series of research teams have repeatedly analyzed personality tests taken by men and women in more than 60 countries around the world. For evolutionary psychologists, the bad news is that the size of the gender gap in personality varies among cultures. For social-role psychologists, the bad news is that the change is going in the wrong direction. It looks as if personality differences between men and women are smaller in traditional cultures like India's or Zimbabwe's than in the Netherlands or the United States. A husband and a stay-at-home wife in a patriarchal(男权的)Botswanan clan(部族)seem to be more alike than a working couple in Denmark or France. The more Venus and Mars have equal rights and similar jobs, the more their personalities seem to separate.

    These findings are so unbelievable that some researchers have argued they must be due to cross-cultural problems with the personality tests. But according to new data from 40.000 men and women on six continents, David P. Schmitt and his colleagues conclude that the trends are real. Dr. Schmitt, a psychologist at Bradley University in Illinois and the director of the International Sexuality Description Project, suggests that as wealthy modern societies level(使平等)the barriers between women and men, some ancient internal differences are being developed.

    The biggest changes recorded by the researchers involve the personalities of men, not women.

    Men in traditional agricultural societies and poorer countries seem more cautious and anxious, less confident and less competitive than men in the most progressive and rich countries of Europe and North America.

    To explain these differences, Dr. Schmitt and his partners from Austria and Estonia point to the hardships of life in poorer countries. They note that in some other species, environmental stress tends to extremely affect the larger sex. And, they say, there are examples of stress decreasing biological sex differences in humans.

    You don't need to get in a time-traveling machine to see how technology will reshape our lives, such as the way we shop. Several new technologies that are to change your buying habits already exist. Let's see what's waiting for your future shopping.

    Try it on, virtually(虚拟的). Want to shop online for a new pair of eyeglasses? You don't need to guess which pair looks best on you. Go and see the eBay Fashion iPhone app to try a pair of eyewear you're checking out on a picture of your face. But what if you want to buy something bigger? Thanks to Microsoft Kinect's motion tracking camera, you can cover clothes on your screen body. You can even choose the background of your virtual fitting room to enrich your shopping experience.

    Get a perfect, custom fit. Everyone's body is shaped differently. To get a perfect fit, you sometimes have to get your clothes changed. But by using 3D scanning(扫描) technology, all the clothes you buy will fit your body perfectly. Some companies scan your body using High-tech to get the most exact sizes, so they can make special clothes just for you.

    Experience high-tech shopping carts and checkout counters. High-tech shopping carts could, in time, be a common sight in malls and supermarkets. Microsoft Kinect-enabled carts are under test at present. The cart can follow you along the aisles (通道), controlled only by your movement and your voice. In China, a supermarket chain(连锁超市) introduced tablet-equipped carts that guide shoppers around the stores' aisles.

    In the United States, several supermarkets use a device(装置) called Scan It that gives buyers the freedom to scan goods on their own while they shop. While it's great not having to line up at a checkout counter, we wouldn't mind it if the store used Toshiba's new Object Recognition Scanner. The machine identifies(辨认) a product as soon as it's placed in front of a camera just by its shape and color, even if it has no bar code(条形码).

Taking photos while on holiday is not an uncommon activity. Tourists do it all the time, but if you want to take things further, here are some tips that can help you along the way.

First of all, there is the matter of equipment. Of course, most people believe that the higher end your camera is, the better the photos will turn out. {#blank#}1{#/blank#} The quality of DSLR cameras (数码单反相机) is superior to the one of small cameras and smartphones, but only if you know how to adjust (调整) their settings. However, if you don't know how to do it, an iPhone camera is enough too. {#blank#}2{#/blank#}You can shoot amazing photos without having to travel with a large and heavy camera.

Secondly, you need to do some research in advance and discover the best photo spots. Your photos don't have to look like travel cards. On the contrary, you can catch the beauty of a place by finding its uncommon corners and subjects. For example, if you're going to a crowded city, don't just take photos of high buildings. {#blank#}3{#/blank#}You may see a new face of the city at that time.

Thirdly, you have to be patient. {#blank#}4{#/blank#}For the best picture, come back to the same spot several times or stay at one spot for some time. You might come across something special as you wait: a bird flying across an old temple, a mother and her baby passing by, or just the sun giving beautiful colors on the roofs. {#blank#}5{#/blank#}

Take as many photos as you can and don't be disappointed if your first travel photos are not National Geographic material, because they will get better with time.

A. So this is the most important.

B. But that is only true in a way.

C. Its quality has increased a lot.

D. Don't forget that practice makes perfect.

E. I also enjoy photographing animals.

F. You may have to take several shots until you discover the right one.

G. Try street photography or take pictures at night.
