Biofuels
Biofules have been around as long as cars have．At the start of the 20th century, Henry Ford planned to fuel his Model Ts with ethanol(乙醇)．But discoveries of huge petroleum deposits(储量)kept gasoline and diesel(柴油)cheap for decades, and biofucls were largely forgotten．However, with the recent rise in oil prices, along with growing concern about global warming caused by carbon dioxide emissions, biofuels have been regaining popularity．
Gasoline and diesel are actually ancient biofuels．But they are known as fossil fuels because they are made from plants and animals that have been buried in the ground for millions of years．Biofuels are similar, except that they're made form plants grown today．
Much of the gasoline in the United States in blended with a biofuel-ethanol．Countries around the world are using various kinds of biofuels．For decades, Brazil has turned sugarcane into ethanol, and some cars there can run on pure ethanol rather than as additive to fossil fuels．
On the face of it, biofuels look line a great solution．Since plants absorb carbon dioxide as they grown crops grown for biofuels should suck up about as much carbon dioxide as comes out of the tailpipes of cars that burn these fuels．And unlike underground oil reserves, biofuels are a renewable resource since we can always grow more crops to turn into fuel．
Unfortunately, it's not so simple．The process of growing the crops, making fertilizers and pesticides, and processing the plants into me!consumes a lot of energy．Also, because much of the energy used in production comes from coal and natural gas, biofiiels don't replace as much oil as they use．
A listener has written from China for advice about how to lose weight. Michael in Shanghai says he is 26 and has battled obesity for most of his life.
Obesity , a severe weight problem, is a complex condition. A doctor may advise taking medicine along with changing one’s the way that he or she behaves. Experts say that the most successful weight—loss plans include a well-balanced diet and exercise.
People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use. To lose weight, you can reduce the number of calories you absorb, increase the number you use, or both.
A recent study looked at four of the most popular dieting plans in the US. Researchers at Stanford University in California studied over 300 overweight women, mostly in their thirties and forties. Each woman went on one of the four plans: Atkins, The Zone, Ornish or LEARN. The women attended diet classes and received written information about the food plans.
At the end of the year, the women on the Atkins diet had lost the most, more than four and one-half kilograms on average. They also did better on tests for cholesterol levels and blood pressure.
Christopher Gardner, who led the study, says the Atkins diet may be more successful because of its simple message to eat less sugar. He also says that the advice to increase protein in the diet leads to more satisfying meals. He says that there was not enough money to study men, but that men would probably have similar results.
Last week, another report based on thirty-one studies suggested that only a small minority of people have long-term success with dieting. Most dieters regained their lost weight within five years and often they become more overweight. But those who kept the weight off generally were the ones who exercised.
