How can I become a better person？ This question has been in my head for long． As students， we spend most of our time studying． I know learning at school， of course， makes us better persons， but I always dream of doing more．

Last year，I got to know a group of autistic （ 患自闭症的） children． We called them "the Snails （蜗牛）"．It was hard to communicate with them at first， because they wouldn't like to． After a two﹣week training， I became more skilled． I got closer to them day by day． To my surprise， I found that every one of "the Snails" had his or her own talent． And their colorful pictures on the wall attracted my special attention， though it was difficult to tell what they were trying to express．

Moved by their pictures， I decided to hold a charity （慈善） sale． We walked on the busy street， selling their creative pictures． We sold 60 pictures that day． People thought their pictures were full of imagination．

Back to the question about how to become a better person， I think I am lucky enough to get my own answer．

（1）Do "the Snails" have their own talents？ 　　

（2）How many pictures did they sell that day？ 　　

（3）What is the writer's answer to the question "how to become a better person" ？ 　　

（4）Do you think that selling pictures on the busy street is a very good way to help "the Snails" ？Why or why not？
