I enjoy doing physical training in my free time. Yesterday, when I was working out at a gym on my lunch hour, I saw    71   elderly lady there riding on a bike. She could’t walk very well,  72 she had a cane (手杖) near her, but she was still there     73   (work) hard.

After I finished my exercising, I told her that I was going to wait for her    74  she got done and that I would walk her out to her car. It was a little far to her car and it was a   75   (fog) day yesterday in Missouri. I walked her to the car and opened the car door for her,    76   won me her big smile and gratitude.

I know    77   is a small thing, but I felt so good inside for helping her.    78    my help, she could have fallen so    79   (easy) out in the wet parking lot, and no one would have known she had fallen. I    80    (know) she needed my help, and her smile was enough to make my day.
