参考答案：A
I take the train into work every morning from a train station near my house. I can get to the station quite 31 because there’s a short cut(捷径) to the station. But in the summer, it can get quite smelly because of all the 32 . So I always try to 33 through it. Today I was trying to do so as usual when something made me stop for a moment. I saw the most beautiful 34 by an old woman walking in front of me with the help of a white stick. She was short and 35 and had white hair. She was walking 36 as each step took some effort. I hadn’t specially noticed her at first, until she stopped near a rubbish bin. She slowly placed her walking stick 37 the rubbish bin. Then she leaned(倾斜) on it with her right hand. She bent down and reached for the rubbish. She clearly found it difficult and it took her a while. She 38 some rubbish with her left hand and slowly straightened herself up again. All the while she used the rubbish bin to 39 herself. She threw the rubbish inside the bin and then 40 walking. It all took her great effort. There’s so much rubbish and no one ever does 41 about it. I was moved to see this old woman make such a great effort to keep even a small part of it clean! I haven’t been able to 42 thinking about that all day. I want to follow her example. I’ve decided to pick up rubbish off the ground if I meet from now on. I hope people will do the same as I do.
