Passage Two

　　Officials at the Olympic Games taking place in Salt Lake City, Utah, say they have met their environmental goals. However, environmental groups say the Salt Lake Olympic Games have done permanent harm to the area. Protection of the environment is now officially one of the three goals of the Olympic movement. The other two goals are sports and culture. Today, many cities seeking to hold the Olympic Games promise to offer greater protection for the environment. However, an environmental group says that the Salt Lake Olympic Committee make promises that it has not kept. For example, activists criticize ski jumps that were built into the sides of the mountains. They also criticize the officials for permitting trees to be cut down and new roads built for the Olympic Games. They said better public transportation is needed to help decrease air pollution during the Games. And they said not enough has been done to reduce energy use. Lawyers say the Olympics are being used as an excuse to permit development that normally would be unacceptable under the current environmental laws.

Passage Three

　　Diet, diet, diet! It gets to be a constant battle for many of us to stay fit and healthy. But diets don’t always allow us to learn new eating habits, improve our self-image, or make lifestyle changes. Developing good eating habits and proper exercise is a permanent issue. And it’s the main topic of this workshop.

　　In order to keep a healthy diet and minimize the risk of disease, it’s essential to eat a diet that consists of low fat foods and to maximize energy with carbohydrates. Beef, nuts, oils, and most dairy products are rich in fat, so you should eat less of those; while pastry, rice, potatoes, and bread contain almost no fat and are a high energy source of complex carbohydrates. You know that many food manufactures use sugar to make low fat or fat free foods taste good, but don’t worry too much about that. You don’t necessarily “get fat” by eating sugar, since sugar is an indirect fat.

　　When you exercise, carbohydrates are the first calories to burn, if you want to burn off fat, it’s good to do some sort of aerobic exercise such as biking, swimming, running, or fast walking. But you have to keep doing this exercise for at least twenty minutes because it takes about that long before we start to burn fat. And then the effect of burning fat decreases after forty-five minutes of exercise. So if you do some sort of aerobic exercise for three to four days a week for about thirty to forty minutes, you’ll have an affective schedule for reducing weight.
