Some people live in the world for body while others for dignity(尊严).

I once took a walk along the street   小题1: a Saturday dusk, with a Pepsi can in my hand. An old woman in ragged clothes,   小题2: was living on collecting used cans, jars and tins, moved slowly towards me, with a bag on the back!   小题3: (walk) nearer, she looked up at me and then fixed her eyes on my can. At that time, I hadn’t finished my cola, so I gave  小题4:  several coins instead.

She stared at me for a few seconds   小题5: handed back the money. Quite confused, I asked: “Why not? Isn’t that   小题6:you want?”

“I am not a beggar,” she said   小题7: (serious), word by word.

Instantly, I felt so sorry. I had intended  小题8: (help) her, completely misunderstanding her. Thus I hurt her. What I could do at that moment was only to drink up the cola and handed her   小题9: emptied can. This time, she gave me a smile with   小题10:  (satisfy) and gratitude in her eyes. The woman is poor in material life but is so respectable as a man. I am not only moved but also have learned a good lesson.
