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 45 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 effective schedule for reducing weight.
Questions 30 to 32 are based on the passage you have just heard.
30. According to the speaker, which will burn most quickly with exercise?
31. What does the speaker say is burned at the beginning of exercise?
32. According to the speaker, what is the most effective exercise time schedule for reducing weight?
选项
A、Nuts.
B、Potatoes.
C、Vegetable oil.
D、Dairy products.
答案
B
解析
选项均为食品名称,故听音时应留意短文中有关这几种食品的描述。由短文中的…potatoes,and bread…are a source of complex carbohydrates和carbohydrates are the first calories to burn可知,属于碳水化合物的potatoes在锻炼时燃烧得最快,故答案为B)。
