阅读理解。 As a young boy, I lived in a poor suburban neighborhood. I often wandered around the neighborhood alone, and offered to help mow a lawn or wash some walls in exchange for some pocket money just to buy something I needed, such as some school clothes or candy. One day, I knocked at an old woman's door and asked if she needed her walls washed. She asked why I wasn't in school and I showed her my pants and shoes, which were torn and no longer keeping my feet warm. She allowed me to work in the yard for pretty much that entire day. When I was finished, I knocked on her door and she looked at me. 'I suppose you want to be paid now,' she said. 'Yes, ma'am, I do.' She asked what my fee was. I hadn't thought about this and made no answer. She said, 'Well, come inside,' and then she came in and pulled out a big jar which was filled with dollar bills. She said, 'Though you've done a fine job today, that isn't something you should be doing again. I want you to buy some pants and new shoes and get back in school. I also want you to come back and visit me with your report card and I'll reward you when I see your good marks. Now reach in with your hands and take out as much as possible.' I reached in and grabbed lots of money, which was enough for me to buy those I needed. I returned several times to see the woman and yes, she did just as she promised. She looked at my report card and gave me a handful of dollars and a sandwich every time I showed her I had an 'A' or 'B'． I'll never forget the huge difference this wonderful stranger made over my life with her generosity and kindness; this is something I hope to do myself in my life. 1．What was the writer's purpose of helping his neighbors?(No more than 10 words) ________________________________________________________________________ 2．Why did the writer show the old woman his torn pants and shoes?
