阅读材料，完成下列要求。

    改革开放以来，经过全国范围大规模开发式扶贫，我国贫困人口大量减少，但扶贫开发工作依然面临十分艰巨而繁重的任务。

材料一：某县是国家扶贫开发重点地区，近年来政府大力支持惠农产业，但因市场信息不对称、项目不符合当地实际等原因，农民实际收益有限，一些群众对政府的扶贫项目极其排斥。针对这种现状，当地政府改变扶贫策略：不再要求农民“认领”扶贫项目，不主动资助农民创业，而让其完全成为农民个人行为、市场行为；为那些有基础、有干劲、有思路的农民提供个性化服务，帮助其申请资金支持和技术指导。观念一变天地宽，该县的扶贫工作取得显著成效。

材料二：有人认为，落后地区的贫困，归根到底是由当地落后的文化习俗造成的，如人们不思进取，坐等救济，早婚，多子，不重视教育等观念导致“懒生穷”°

    另有人认为，贫困地区文化习俗落后的根源，恰恰在于恶劣的生存环境和落后的经济状况，不是“懒生穷”而是“穷生懒'。

   How old was I? I can’t remember. Maybe I was only 10. It was the first 1 without my father because he was away for something. He left me to fill that sad place in my mother’s heart. It was the Christmas when I stopped being a 2 and tried to play Father Christmas myself. I really wanted to make it happy and bright again. It was the Christmas of the 3.
   Mom first saw the coat at Tobias, a nice 4 shop in our town’s little shopping mall. It was dark green. And it was a 5, heavy, wool dress coat. Mom pulled it out from the rack(架) and held it up. “Long enough,” she said in a low voice and 6.
“I need a new coat,” Mom smiled before the mirror. She looked good on any clothes, 7  this coat suited her much better. She looked at the 8, then hung the coat back on the rack, standing there once more to 9
   Eighty-seven dollars. But I decided to buy it for her. As we moved on 10 the mall, I found some excuse to return and asked one of the Tobias ladies to 11 the coat.
   I helped clean every yard(庭院) in our neighbourhood—some yards twice, and soon I got the coat. The store ladies helped me put it in their biggest 12 with bright blue paper and thick silver ribbon(丝带). I don’t remember 13 I got it home, but I can still feel the wonderful 14 and pride that filled me. I would imagine the big space which the box would take up under our tree. Here it was—joy, peace and15 —all in the box, waiting for Mom’s surprise
