课时跟踪练(三) Lesson 2 & Lesson 3 — Pre reading

Ⅰ.阅读理解

A

Speed walking has now become part of my daily

routine for six years.I am always 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.
