(二)阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 When I was eleven years old, I moved to Tampa, Florida.My parents traveled for a living, so Aunt Emily took care of me while they were away.One rainy morning, there was an old lady who was dressed in a bright orange coat carrying a rubbish bag and a stick.“What's that old lady doing？” I asked Emily, pointing out of the window to the street in front of the house. Hearing my question, Emily answered, “She's picking up rubbish around here for fun.” “Oh，” I answered.“Interesting ...Why would someone think picking up rubbish is fun？” For a long time, I often saw that old lady — rain or shine — on my way to school.In the beginning, I thought she was crazy to pick up rubbish.However, I finally smiled and waved at her each time I saw her. Later, when I moved to college, I'd see rubbish in the grass and feel really angry about it.I'd think, “Why isn't anyone picking up rubbish? People are so unconcerned！” But shortly after that, I said to myself, “Why do I think picking up rubbish is someone else's duty？” And I couldn't walk past trash without feeling guilty. So while walking in the college, I began picking up rubbish and made sure the campus was in a better situation than I previously found it.My behavior influenced some students.They started to help me out. Like me, they also picked up rubbish whenever they noticed it.And our college became more beautiful.Seeing that, I began to think, “If I can pick up rubbish outside the college — in other places of the town, it may make a big difference to the town.” But picking up rubbish in front of many people outside the college needs courage.It could be embarrassing.But it was the right thing to do.I decided to try it. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 So one day I called up all my courage and collected rubbish on a nearby street.　 ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ I thought if more students took part in the voluntary activity, things would be much better. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 参考范文： So one day I called up all my courage and collected rubbish on a nearby street.Some people watched me with a strange look that seemed to say I was crazy.And suddenly, I remembered that old lady, who often picked up rubbish years ago.The interesting thing was that I was acting just like her! As strange as it might seem, picking up rubbish is kind of fun for me! Gradually, many people realized I was volunteering to help make our town cleaner.They praised me and thanked me.Then I decided to encourage more students to do this in the town. I thought if more students took part in the voluntary activity, things would be much better.We bought each student a bright orange coat with words on it：Let's make our town cleaner! And we took time to not only pick up rubbish but also sort through it and recycle it.Something amazing happened — the strangers around us helped us out too! I thought to myself, “The old lady made all this happen; she set a good example to us and made a big difference in our life.” 学科网（北京）股份有限公司 $
