阅读理解。 My First Long Run Two weeks ago,I had a quarrel with my husband. After he had driven off in anger,I realized that I wasn't going to feel any better just sitting there.Feeling abandoned andguilty,I put on my gym shoes to get some fresh air. Our driveway has a slope (斜坡)that is easier just to jog downif you are lazy,takipg advantage of gravity.Instead of stopping at theend of the slope,I decided to see if I could just jog to the end of thestreet.1 had tried a few months ago and failed miserably,Since thatfirst attempt I had been jogging regularly and was significantly fitter,but still very lazy.However this time around I managed to reach thestop sign with ease and I figiired I would go a little further. After about one kilometer, however, I noticed that my upperbody was tense. To make the moveinent easier I had to relax my body,and tried to take deep breaths of fresh air. I kept  giving myself the excuse  to  stop. No  one  would  bedisappointed. No one would even know. But I didn't stop.I wanted tokeep going harder , better , faster , stronger. To my great surprise , I ran4. 9 km in 31 minutes. When I got back,I had tears in my eyes. I didsomething I thought I could never do. It was the first run of my life. Since then,I have improved mystride ( 步幅 ) and time. After every run I feel fitter, happier andmotivated to keep progressing.I love the runner's high. I normally jogbecause I want to look good. I want to run because it makes me feelgood. 1. Why did the author feel guilty? ( No more than 9 words) __________________________________________________________________ 2.
