Car sharing is another way to drive green that’s gaining in popularity, especially in urban areas．People who may not drive every day but still want a car to run errands （差事）or drive on weekends benefit most from car sharing．Car sharing is usually run by a service like Zipcar, though there are non-profit （非营利的）and informal car sharing services．Members pay a monthly fee and have access to an entire fleet of cars when they need one．The cars are par ked in fixed spots around the city, so members only need to make a reservation, and then go to the pickup spot．
Car sharing has major environmental benefits because it reduces the number of cars on the road．Members don’t drive just because they are in a car．They plan trips, and if they don’t need a car, they don’t use one．Still, a car is available to them if they need to make a bi g trip to the grocery store, pick someone up at the airport or if they want to go to the beach for the day．Members also benefit by having access to a car without any of the headaches of ownership．They usually don’t have to pay for the gas, insurance or maintenance （保养）, and the monthly membership fee is less than a typical car payment．So if you really want to go green but aren’t ready to totally give up a car yet, car sharing may be the way to go．
If you still need to get around, but want to go even greener than sharing a car, share a bus!

Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years. And indeed, cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates（碳水化合物） have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates — which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body —— dietary fat is more easily converted to body fat. Therefore, it’s more likely to stay on buttocks, thighs and bellies.
But cutting fat from your diet doesn’t necessarily mean your body won’t store fat. For example, between nonfat and regular cookies, there’s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight again. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn’t losing weight. Then he showed his food diary to his coach and revealed he’d been eating half a pound of jelly beans a day. “They don’t have any fat,” he explains. But they had enough sugar to keep him from shedding an ounce. 
Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt（酵母乳）that contained exactly the same amount of calories. One group’s yogurt label said “high fat”—the other, “low fat.” The “low fat” yogurt group ate significantly more calories later in the day than the other group. “People think they’ve saved fat and can indulge themselves later in the day with no adverse consequences,” says Richard Mattes, a nutrition researcher at Purdue University. “But when they do that, they don’t compensate very precisely, and they often end up overdoing it.”
