問題文 A. I have recently started to walk to the place where I work. I want to lose some weight, and I thought walking would be the best way to get some daily exercise. I normally get up early, so I have enough time.

B. Moreover, running along streets can be very hard on your knees and ankles, while walking isn't. So I think I shall continue to walk.

C. But she added, if I run, I will get to work three times faster. So, whether I walk to work or run to work will make no difference in the amount of calories I use up, only in the amount of time it will take.

D. I was telling some of my friends about this, and one of them pointed out that if I was really serious about losing weight, I should run to work instead. What he said seemed true, since running uses up many more calories than walking.

E. If I were worried about time, then, it woudl be better to run. But I am worried about it, and also, I do not like the idea of arriving at work hot and out of breath.

F. But another friend said the matter was not so simple. She explained that a person running at 10 kilometers an hour burns about 11 calories every minute. This is around three times the amount you would use each minute if you were walking at just over 3 kilometers an hour.
