Yesterday afternoon, my parents and I go to the     
supermarket near my home to buy some food. In the              
way back home; I saw several teenager of my age                    
wandering aimless around the square. They were shaking           
with cold and looked even if they were very hungry. It was        
such a cold night that I felt pity for him. I remembered           
a  food we had bought and gave it to them. Then we walked        
home silently. I felt happy to be able to give others hand.     
My parents also felt very proud at me. They said we should        
do all we could to helping people who are in difficulty.           		1. _____
