I was in my parked car, holding a book and reading. Once in a while I looked up, watching the people passing by. When I raised my    35   again, I saw an old lady with a large bag walking slowly towards my car. The bag seemed not only to make her steps    36  , but also make her out of breath. She looked tired and I thought she must be more than 70 years old.

She stopped and put a hand out to rest    37   it, gently (轻柔地，徐缓地) closed her eyes and took a deep breath.

Was there a way I could do something? I tried to keep my body still while my mind    38   for answers. However, because of my careless head movement, she noticed me, and she    39  moved her hand away from the car. I picked up a bottle of water at once, gently opened the door and offered the bottle to her. She    40   me, and then shook her head and walked away.

I was so    41   with myself. I should have been more careful not to move. Instead of    42   a hand, I had interrupted (打扰，中断) the old lady’s    43   moment of rest. I was feeling blue. Just at that moment, I saw the lady coming back again. I opened the door and patted (轻拍) the    44   next to me. She sat down, opened her bag and offered me a banana. I took it and offered her the bottle of water again. She took it.

I ate, she drank and we smiled. She    45   for a couple of minutes. Those minutes brought such quietness to me. Then she took my head in both her hands, made a small kissing    46   in the air, opened the car door and walked away.

I was trying to help someone in distress (困苦，苦恼). In turn, I became distressed and she took away my distress and replaced it with quietness.
