Mr Jenkins liked all kinds of delicious foods. As an important officer, he was often asked to dinner. The shopkeepers tried their best to fawn on him. They knew it was good for their business. Now the officer got fatter and fatter. He could hardly go upstairs at home and had to sleep downstairs. He often felt tired if he walked or did some housework. He was worried about it and had to go to see a doctor." Stop eating much fat(脂肪) and sugar, Mr Jenkins," said the doctor. "Or it will be worse for your health!" It was difficult for the officer to do it. He wouldn't do as the doctor said. Of course, he found something was wrong with his heart a few months later. Now he thought the doctor was right. And he had to be in hospital." You must lose weight(减肥), sir," said the doctor. "Unless you want to die soon!" "Could you tell me a way to lose weight, please?" "You must do exercise first." "Which kind of exercise?" "To move your head from side to side when you're invited to dinner!"

    Doris and Samuel are having diner in a restaurant.

Samuel: I think I'll have a hamburger, some chocolate cake and a large glass of cola. How does that sound to you?

Doris: That sounds 1 ! I'll have a chicken sandwich, a salad, an apple and a glass of lemon tea. I've decided to stay away from fried food and soft drinks.

Samuel: Why?

Doris: I had my medical examination(体检). The doctor said that I needed to2 . He also told me to have a more balanced diet.

Samuel: What's a balanced diet?

Doris: A balanced diet means having different kinds of healthy food every day. We should have plenty of fruit, vegetables, noodles and bread. And, we should have 3 dairy products(乳制品) and eggs and less meat.

Samuel: But I believe my diet is balanced.

Doris: 4 ? Do you remember what you had today?

Samuel: Oh, the usual things. For breakfast, I had fried eggs and a large cup of coffee with a lot of milk and sugar. For lunch, I had six chicken wings and a glass of cola.

Doris: I don't understand 5 you say that it is a balanced diet!

Samuel: OK, you are right. I'll change my diet. Here comes my hamburger and chocolate cake!
