Directions: Translate the following passage into Chinese and put your translation on the ANSWER SHEET.It’s exhausting，time consuming and although it counts as physical activity，housework does not improve health or help to shed those excess pounds, British researchers said．Brisk walking is a much healthier option and a better way to keep fit than mopping floors, dusting and cleaning windows，particularly for older women between the ages of 60—79. In a survey of more than 2,300 elderly women in Britain，10 percent said they enjoyed brisk walking，one percent did more than 2.5 hours of gardening a week and more than half reported doing heavy housework. But the researchers said although housework requires physical activity it does not seem to have any health benefits．Women in the survey who walked vigorously for 2.5 hours a week or did an equal amount of gardening were less likely to be obese and had a lower resting heart rate，which is a sign of physical fitness．Although housework requires effort, more research needs to be done on its long—term benefits before it can be included as a health—promoting activity．
