For the most part, rapid economic development has been a boon. But there is a down side to development—health problems such as overweight are all becoming more prevalent, as more people take taxis to work instead of riding their bicycles, and other labor saving devices become more popular. An increasingly fast pace of life makes it difficult for people to spend time working out or playing sports. "I know exercise is good for your health," a young lady said "But after a busy work week, the only thing I want to do is to watch some TV and go to sleep." That attitude may explain the results of a recent nationwide study, which suggested 15 percent of urban adults in China are overweight, a large number of people over the age of 40 suffer from high blood pressure and cardiac ailments (心脏病). Local researchers found that 31.2 percent of elderly respondents were getting enough exercise, but less than 9 percent of youngsters and the middle aged got an adequate amount of physical activity. Elderly people understand the importance of protecting their health. The young people, however, are busy working and use this as an excuse to avoid exercise. In fact, physical exercise doesn’t require much time, money or a special gymnasium. People can make use of any time and any place at their convenience to take part in sports. Walking quickly, cycling, climbing the stairs and dancing are all helpful methods to enhance one’s health. The benefits of adding a little more activity to your life are priceless. "There is no need to be an athlete, however," a local doctor said people should walk for 30 minutes a day and take part in some other physical activity three to five times a week. He warns, however, that people in poor physical shape should start slowly, and build up over time.
A.it has benefited the general public greatly B.it has done harm to people’s health nationwide C.it is going faster than anyone could have imagined D.it has helped to establish a positive and healthy lifestyle of the public
