Task 1 I have always felt proud of my good health because I sometimes only had to take one day off when I had a cold. So I got unhappy when I met with my doctor in the street one day. He told me that I was too heavy and if I didn’t lose weight, I would have heart trouble. He added that like many middle-aged men, I lived too easy alife. I sat behind my office desk in the day and sat before the TV set in theevening. My doctor advised me to go on a diet ( 节食 ) at once. I tried, but failed. I like my food very much and my wife is a very good cook. I then decided that it was all a question of exercise. I decided that I would not go to the seaside for holiday this year. There you could do nothing but go down to the beach and lie in the sun. I would not take my car, either. I knew we would drive about everywhere in it. We chose a village far away from the city. There was no road for car there and we could walk every day. After our first day’s walk I felt very tired, but we went on walking. I began to feel healthier and healthier. However, with so much exercise, I had a healthy appetite ( 胃口 ). When Igot back home, I found that I hadn’t lost any weight. I had become heavier. 1. Why does the writer feel proud?
