David found that he was a bit fat these days. He went to buy an exercise machine so that he could try to lose some weight(减肥).
At first, he put it in the basement(地下室).But he did not use it often. He seldom went into the basement.
Next, he moved it into his bedroom. But he still didn't use it very often. That's because he would only go into the bedroom when it was time for him to go to sleep.
Finally, he moved it into the living room. He put the machine next to the window. His wife thought maybe this would finally work. He could exercise and look outside at the beautiful garden at the same time.
After a week or so, his wife asked David how his exercise was going. He said, "Well, yes, I do a little more exercise these days. Every time I want to open the window, I have to walk around the exercise machine."
