1 . It has always been thought that alcohol causes people to put on weight because it contains a lot of sugar, but new research suggests a glass a day cold form part of a diet. Looking at past studies they found that, while heavy drinkers do put on weight; those who drink in moderation can actually lose weight.
A spokesman for the research team at Navarro University in Spain says, "Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain." The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that data do not clearly indicate if moderate drinking increases weight.
Boston University’s Dr. Harvey Finkel found that the biologic mechanisms(生物学机制) relating alcohol to changes in body weight are not properly understood. His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病), which relate to increasing obesity. Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.
The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods. They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.
For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese. What’s more, a study three years ago suggested that resveratrol(白藜芦醇), a compound present in grapes and red wine destroys fat cells.

I have listened to music all my life. When I was twelve years old, the Beatles came to America and my whole world opened up. Maybe young people today cannot understand the influence of the Beatles when they exploded across America. Their influence changed the way we dressed, looked, acted and spoke... even our culture. The Beatles arrived in America from the UK just under three months after the assassination(暗杀) of President John Kennedy, which had put America into a great depression. And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.
Music links the heart of the hearer with that of the composer. This means that it mixes the spirit of the composer with your spirit when you listen to it. And the music can take your spirit out of your body and transport you into another world. Music has a great way of touching people. Music can make you laugh, cry or shout. It's also a great source of inspiration.
Try this one day and notice what happens: make yourself a cup of tea, sit on your sofa and play one of your favorite songs. Close your eyes, and soon you'll find yourself creating vivid mental images—matching the music that you are listening to.

Where should an adventurous tourist go? After you've done sightseeing in London, shopping in New York, tasted the local food in Paris, and danced to your heart's content at the Brazilian Carnival, where else can you go? What exotic (异国风情的) tourist destination awaits you?
Well, Antarctica sounds like the holiday of a lifetime! It's considered the last great wilderness on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can cope with the low temperatures.
Tourism began in Antarctica in the 1950s and it's still a small scale. About 37,000 tourists are expected there this season, but many won't even leave the boat.
The BBC's Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave footprints and they all go to the same place, the accessible coastline, which is also where the penguins and seals go to breed.
But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.
According to Rix, guidelines are followed when you're about to set foot in Antarctica and tourists have to disinfect (为……消毒) their boots to make sure no alien species are introduced.
And once on land, there's no eating or smoking. Rocks, bone fragments — nothing should be taken as a souvenir and nothing should be left behind. Tourists fortunate enough to visit Antarctica must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.
