2019学年度北师大版选修七Unit 21 Section Ⅲ Lesson 2 & Lesson 3 Pre­reading阅读学案设计

Speed walking has now become part of my daily routine for six years.I am alw ays keen to do it regularly without a break.Even though I am neither a physician nor a specialist in medical science, I am fully aware that exercise, especially speed walking, helps maintain health and lowers the chance of falling ill.

I urge everybody to speed walk on a daily basis, with one day off a week, or at least to do it three times a week. I managed to burn around 17 kg of fat after taking up speed walking. This should also be accompanied with a change in diet. We need to reduce how much we eat and avoid junk food, sweets and carbonate drinks. Reducing the amount of food we eat in the evening by around 80 percent and increasing how much water we drink are also good practice. Overeating should also be avoided.

I usually walk at a speed of 1 km per 8. 5 minutes. It will initially make you tired. However, over time it will become a habit and an addiction.

This type of exercise will help you mentally, will also help you sleep and give you an appetite. It will make you physically fit and help burn fat. Speed walking makes you healthy and everyone can find time to walk. The problem is that some people do not plan their days and do not, therefore, find time. We can gain health and social benefits from speed walking. It will help change our lifestyles, fight diabetes, obesity and other illnesses.

Arguments such as "I am too old and obese to walk" do not hold_water. People of any age who speed walk will see the benefits within a couple of months. Walking outdoors is ideal and it is best done in the company of friends.
