The Winter Olympics are also called The White Olympics. At this time, many colorful stamps are published to mark the great Games. The first stamps marking the opening came out on January 25th,1932 in the United States for the 3rd White Olympics. From then on, publishing stamps during the White Olympics became a rule. During the 4th Winter Olympics, a group of stamps were published in Germany in November 1936. The five rings of Olympics were drawn on the front of sportswear. It was the first time that the rings appeared on the stamps of the White Olympics.

In the 1950's, stamps of this kind became more colorful. When the White Olympics came, the host countries as well as the non-host(非主办方)countries published stamps to mark those Games. China also published four stamps in February 1980, when the Chinese sportsmen began to take part in the White Olympics.

    Japan is the only Asian country that has ever held the White Olympics. Altogether 14,500 million stamps were sold to raise money for this sports meeting.

    Different kinds of sports were drawn on these small stamps. People can enjoy the beauty of the wonderful movements of some sportsmen.

    It warmed my heart today to walk into the Thirsty Camel downtown in the Thanksgiving Day, for a quick lunch before a haircut and library trip. Ilan, a food shop owner, said that he was refusing to take money today because it was Buy Nothing Day. To increase awareness(意识) of the stranger's over-spending nature of our society, Ilan suggested a trade for food today. He simply asked that you offer something of equal personal value for the meal you received.

    At first I was really uncomfortable, wondering if it would be fair to exchange a yet to be determined “I Owe You” (IOU) for food? What could I give him of equal value? After all, his food is the best in the town!

    We ended up writing our IOU's with promises of a book, some paintings and the offer of work in a variety of ways if he needs it.

    I think the idea isn't that the trade is “equal” so much as the importance of the kind of transaction. We put thought into our offer and we had an even greater understanding for the meals we ate.

    We don't buy a lot, especially at this upcoming time of year. We don't give gifts at all in fact. The holiday time is spent enjoying each other's company and doing things together with family and friends. This is what seems most sensible.

    Ilan is a good person. We are all lucky to have someone like this in our community.

    We spend a lot of time studying what we eat, but it turns out that when we choose to eat the very last meal of the day may also matter.

    Recent studies found that food was processed by the body in different ways depending on what time of day it's consumed. This might be because of physical activity, changes in body temperature, biochemical reactions and absorption and digestion of food.

    The best time to eat dinner depends on when you get up and go to bed, as well as if and when you eat your other meals. "Breakfast sets you up for success," Planells, a nutritionist, says. "If you don't eat breakfast, by lunchtime you're starving, and by dinner any healthy eating plans are out the window."

    Researchers also found that meal timing had an influence on human metabolism(新陈代谢). They studied a small group of people carrying extra weight and found that those who ate their last meal by mid­afternoon had increased fat burning at night.

    Eating early also seems to be the perfect time for blood sugar control. "Starting around 3 pm, blood sugar control is worse than it is in the morning, meaning that if you ate the same meal at 3 pm as you did for breakfast, your blood sugar levels would rise higher, despite the fact that you ate the same amount of food," Planells says.

    A 10­week study of "time­restricted feeding" looked at what happens to body fat when people limited their meals to a shorter window of time. Researchers found that people who ate breakfast 90 minutes later than usual and ate dinner 90 minutes earlier than usual lost more than twice as much body fat on average as those in the control group, who ate their meals as they normally would.

    In an unmanned supermarket, a customer waits to pay. With the use of advanced digital payment technology, including biological recognition and in-depth learning, the man leaves in a minute. There's no cashier in the store. At a large university, students use a hand-scanning machine that authorizes their entry into the gym. Those people are using "smart machines" which identify people by their physical characteristics. These new devices use fingers, hands, faces, eyes and voices. Some machines may even use smells. This new technology, called biometrics, gets information from parts of the body.

    In the past, biometric machines were used mainly in government agencies or in prisons. But now that the cost of the technology is lower, these machines are starting to be used everywhere, from border services to schools.

    Some people, however, are concerned that these machines will mean the destruction of personal privacy. They worry that the machines will get personal information about them, know it seems like these machines are invading our privacy, but actually, biometric machines help to protect it," says Jay Tarkett, who works at a company that develops the machines, "They can be used instead of passwords on a computer, for example. They can also identify criminals at airports. So, really, they help to promote public safety, and all the information stored is kept confidential by the machine itself."

    Some people don't like the idea of using fingerprints because they associate them with criminals, and feel like they are being accused of something, In addition, they don't work for some people, such as bricklayers, who wear down their fingerprints. Yet, face recognition does work well because the subject doesn't really have to do anything, To cash a check at a bank, for example, the customer has to do nothing more than look at a machine similar to an automatic teller. If the face matches the picture kept on file, the customer gets the money with no problems, The need to carry identification with you from place to place, then, would all but cease. It has been found that the hand scan works well ill the college gym. Before this machine was used, students at the college entered the gym using cards similar to credit cards. The problem was that students often lost or forgot their cards. With the hand-scanning machine, however, the problem was solved right away.

    But the machines are still new, and there can be problems. For example, voice recognition works on the phone, but it is not precise, and can be tricked. Another constraint(限制)we notice；, with machines that use face recognition in particular, is that they can be fooled if people color their hair or gain a lot of weight. However, this particular problem may be solved by a new type of technology that scans a person's iris, the colored part of the eye. It can even identify the person from a few feet away, recognizing a customer as he or she approaches the ATM.

    Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.

    The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. "We never thought that this could be something that could kill," recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.

    Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.

    It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.

    What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It's also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.

    As for dealing with the root cause of the problem, the UN's International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.

    "The ocean is not our world," comments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.
