Fat and WeightEven as Americans have been gaining weight, they have cut their average fat intake（摄入） from 36 to 34 percent of their total diets in the past 15 years. 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（代谢）fat than it does to metabolize other foods.Compared with protein and carbohydrates, fat is more easily changed to body fat. Therefore, it's more likely to store on buttocks（臀部）,thighs and bellies.But cutting fat from your diet doesn11 necessarily mean your body won't store fat. For example, between nonfat and regular cookies, there' s little difference in calories because producers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings（调料）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 decided to eat only 40 grams of fat a day. And later he found that he wasn't losing weight. Then he showed his food diary to a doctor and said 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 stop him from losing an ounce of his weight.Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat every day and gain weight. For breakfast, Prof. Rolls gave two groups of women yogurt that contained exactly the same amount of calories. One group' s yogurt is with “ high fat" label—the other, "low fat". The "low fat" yogurt group ate 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 harmful results, says Richard mattes, a nutrition researcher at Purdue University. M But when they do that, they often end up overdoing it."8.Eating nonfat foods will cause people to intake less calories and stop from gaining weight.

An Introduction to AustraliaDo you know Australia? Australia, the largest island in the world, comprises the mainland of the Australia continent, the island of Tasmania（塔斯马尼亚岛）and numerous smaller islands. It is a little smaller than China. It is in the south of the Earth. Australia is big, but its population is not large. The population of Australia is nearly as large as that of Shanghai. Australia ranks highly in many international comparisons of national performance, such as quality of life, health, education, economic freedom, and the protection of civil liberties and political rights.The government has made enough laws to fight pollution. The cities in Australia have got little air or water pollution. The sky is blue and the water is clean. You can clearly see fish swimming in the rivers. Plants grow very well.Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers' exhibition. There we saw a large number of wild flowers we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flowers' exhibition. After visiting Perth, we spent the day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quickly as we could. There were about three hundred sheep coming towards us down the path.Australia is famous for its sheep and kangaroos（袋鼠）.After a short drive from any town, you will find yourself in the middle of white sheep. Sheep, sheep, everywhere are sheep. The kangaroo is an unofficial symbol of Australia, and appears as an emblem on the Australian coat of arms, on some of its currency, and is used by some of Australia' s well known organizations. The kangaroo is important to both Australian culture and the national image, and consequently there are numerous popular culture references.1.Australia is ______.
