What is a healthy lifestyle,exactly? 1.Healthy diet,which was calculated and rated based on the reported intake of healthy foods like vegetables,fruits,nuts,whole grains,healthy fats,and omega-3 fatty acids. 2.Healthy physical activity level,which was measured as at least 30 minutes per day of activity. 3.Healthy body weight defined as a normal body mass index(BMI)(身体质量指数)which is between 18.5 and 24.9. 4.Smoking,well,there is no healthy amount of smoking."Healthy"here meant never having smoked. Does a healthy lifestyle make a difference? Absolutely yes.According to this analysis,people who had all the four habits enjoyed impressively longer lives than those who had none:14 years for women and 12 years for men(if they had these habits at age 50).Just one healthy habit(and it didn't matter which one)...just one... increased life expectancy by two years in men and women.Not surprisingly,the more healthy habits people had,the longer their life. So what's our big problem? As the researchers point out,in the US we tend to spend more on developing fancy drugs and other treatments for diseases,rather than on trying to prevent them.This is a big problem. Experts have suggested that the best way to help people make healthy diet and lifestyle change is through public health efforts and policy changes. 1.How did researchers study the influence of healthy habits on life expectancy? A.By analysing data. B.By raising questions. C.By exchanging information. D.By comparing developed countries. 2.Which person might have a healthy lifestyle according to the passage? A.A translator who exercises 2 hours a week.B.A librarian who smokes,but not heavily. C.A steward who drinks wine every day. D.A shop assistant whose BMI is 19.5. 3.What is the big problem in the US according to the researchers? A.Changing laws related to lifestyle. B.Reducing money on treating patients. C.Staying focused on drug development. D.Spending much on disease prevention.
