单选题A New Start After Christmas comes the anti-Christmas. If the festive season is all about filing up on the things you like that are bad for you, then the new year is the "Detox season" when people across the western world adopt special diets to lose weight and get rid of the vague feeling that they have spent the last few weeks poisoning themselves. But are Detox diets really necessary? After all, the body itself gets rid of unwanted substances. That's what the liver and kidney are for. "The Detox fad or fads, as there are many methods, is an example of the capacity of people to believe in and pay for magic despite the lack of any sound evidence," says Martin Wiseman, professor of human nutrition at the University of Southampton in the UK. Most of the pills, juices, teas and oils that are sold for their detoxifying effects on the body have no scientific foundation for their claims, according to the research. People would be better off having a glass of water and going to bed early. Detox diets may be magic rather science, but they are the kind of magic which many people want to perform. That may have something to do with the western diet in general. Scientists and dieticians argue that the benefits people feel are not due to their body getting rid of excessive toxins but are due to changing from what is likely to have been a "poor" diet. Having fewer headaches, for example, is probably the result of being fully hydrated due to drinking so much water and better skin may be due to eating more fruit and vegetables. Detox diets may also be dangerous, as they may deprive vulnerable groups--pregnant women, for instance, or growing teenagers of the kind of nutrients they need. Yet their popularity continues to rise. This may be something to do with the way that food works within many western cultures. Generally, a country's food develops along with its economy and society. Food becomes part of a person's cultural identity. In some countries, this link has been broken. In the UK, for example, rapid industrialization in the 18th and 19th centuries saw millions of people move from the countryside to the towns interrupting the development of a national cuisine. The United States, a country of immigrants from many different places, has found it hard to develop a national cuisine. In both places, comparatively few people cook for themselves and food supply is dominated by big processing and agribusiness companies. Detox diets are more popular in these countries than in places like France and Italy, where strong links between food and national culture remain, and where far more people regularly cook for themselves instead of buying processed foods. Perhaps Detox diets are successful because many westerners have lost mast in what they eat. On the other hand, they may help re-introduce people to the kind of food that is necessary for a healthy diet. And after learning that, they won't poison themselves in the first place. This would mean radical changes in the way that people eat across the west. And that would be an unwelcome development for the food industry. From the business point of view, it is much better to sell people the problem and then sell them the solution.

单选题The Writing"s on the Wall? Is it art or is it just vandalism (野蛮行为)? Well, it"s still a crime, but graffiti (涂鸦) has changed since the days of spraying your name on a wall to mark your territory. Street art has become much more sophisticated since a 17-year-old called Demetrius started spraying his "tag", TAKI 183, all over the New York underground in 1971, and hip-hop culture was born. Hip-hop is a mixture of art, music and dancing, poetry, language and fashion. It came from young inner-city people who fell left out by their richer classmates and who were desperate to express themselves in any way they could. An experiment to control the spread of graffiti in Rochdale, Creator Manchester, has been so successful that plans have been made by local street artists for an international convention in June. "We"re planning to get people together from different countries like France and Germany for a week," says Liam, one of the organizers. The scheme started in 2000, and has attracted people of all age groups and both sexes. "We all share a common interest and get on really well with each other." The first site to be chosen was a subway. "Before we began, people were afraid to use the subway. We had it cleaned up and now, with all the artists hanging out down there, people are using it again. People can relate to graffiti much more now." By providing places to display their talents legally, there has been a fall in the amount of "tagging" on people"s private property. Street artists Temper developed his drawing skills at a young age. In art classes at school he was really frustrated because the Art teacher didn"t spend time with him. They thought he was already very good at art and so spend more time with other students. So, at 12 years old, Temper started painting with all these guys he"d hooked up with who were about 22 years old. He looked up to them and loved what they were doing on the streets of Wolvehampion, England. "The whole hip-hop scene was built up of different things and I did a bit of everything. But it was always the graffiti I was best at." he says.

单选题{{B}}第三篇{{/B}} Forecasting Methods There are several different methods that can be used to create a forecast. The method a forecaster chooses depends upon the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents and the degree of accuracy or confidence needed in the forecast. The first of these methods is the persistence method : the simplest of producing a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 37 degrees today, the persistence method predicts that it will be sunny and 37 degrees tomorrow. If two inches of rainfall today, the persistence method would predict two inches of rain for tomorrow. However, if weather conditions change significantly from day to day, the persist-ence method usually breaks down and is not the best forecasting method to use. The trends method involves determining the speed and direction of movement for fronts, high and low pressure centers, and areas of clouds and precipitation (降雨量). Using this information, the forecaster can predict where he or she expects those features to be at some future time. For example, if a storm system is 1000 miles west of your location and moving to the east at 250 miles per day, using the trends method you would predict it will arrive in your area in 4 days. The trends method works well when systems continue to move at the same speed in the same direction for a long period of time. If they slow down, speed up, change ,intensity or change direction, the trends forecast will probably not work well. The climatology(气候学)method is another simple way of producing a forecast. This method involves averaging weather statistics accumulated over many years to make the forecast. For example, if you were using the climatology method to predict the weather for New York City on July 4th, you would go through all the weather data that has been recorded for every July 4th and take an average. The climatology method only works well when the weather pattern is similar to that expected for the chosen one of year. If the pattern is quite unusual for the given time of year, the climatology method will often fail. The analog method(类推法) is a slightly more complicated method of producing a forecast. It involves examining today's forecast scenario and remembering a day in the past when the weather scenario(天气状况) looked very similar (an analog). The forecaster would predict that the weather in this forecast will behave the same as it did in the past. The analogy method is difficult to use because it is virtually impossible to find a predict analog. Various weather features rarely align themselves in the same locations they were in the previous time. Even small differences between the current time and the analog can lead to very different results.
