Last year, I worked near my mother's house and stayed with her for a month. During that time, I helped her do some housework and 1 some food.
A week later, I noticed that the food ran out very2 . Then I began keeping an eye on my mum. To my3 , I found that she would put some food into a bag and go out with it every morning. And finally, I decided to4 her. I saw her taking the food to the street children and spending a lot of time talking and playing with them.
One day, I talked with a neighbor and found out that my mum was well-known in the area. The children were very friendly to her and even thought of her 5 their own mother. Why didn't she tell me about it? Was she worried that I would 6 buying food if I knew the truth(实情)?
When my mum got home, I gave her a7 hug(拥抱). I told her she didn't need to keep 8 a secret(秘密)from me. And she told me something about the children. Some of them lived with an old lady in a small house. Others slept on the street. 9 she told me everything, I was so moved by her kindness.
I continued to buy food for my mum after that. But I 10 added one more bag for her other "children".
