阅读理解。 Just a Little Smile Mark was walking home from school one day. He saw the boy in the front drop all of the books he was carrying, with two sweaters, a basketball and a walkman . Mark stopped and helped the boy pick up these things. Since they were going the same way, he helped to carry some of his things. As they walked, Mark knew that the boy's name was Bill, that he loved computer games, basketball and history, and that he was having lots of troubles with his other subjects and that he had just broken up with his girlfriend. They arrived at Bill's home first and Mark was invited (邀请) in for a Coke and to watch some television. The afternoon passed happily with a few laughs and some small talk, then Mark went home. They often saw each other at school, had lunch together once or twice, and then they both finished middle school. They ended up in the same high school where they sometimes saw and talked with each other over the years. At last just three weeks before they finished high school, Bill asked Mark if they could talk. Bill asked Mark if he still remembered the day years ago when they had first met. 'Did you ever think why I was carrying so many things home that day?' asked Bill. 'You see, I cleaned out my locker (锁柜) because I didn't want to leave anything for anyone else. I had put away some of my mother's sleeping pills (药片) and I was going home to kill (杀死) myself. But after we spent some time together talking and laughing, I began to understand that if I killed myself, I would have missed that time and so many others that might follow. So you see, Mark, when you picked up those books that day, you did a lot more. You saved my life. ' 1. When Mark met him the first time, Bill was going _____.
