    The Fitting-in of Suzy Khan

    The first time I saw Suzy Khan, I knew I had to help her. She was really small for her age of 12. The boy in my class often1about her and laughed their heads off. She would open a book, pretending to read, with tears dropping on the open page.

    All I knew was that she was an orphan(孤儿) from Africa. She had just been adopted by a family in town who2that the best way for her to learn American ways of life was to be with American kids. I looked down at this 3girl and promised myself that somehow I would help her.

    But how could I help her4in with us? There had to be a5

    One day, when I went into the classroom, I saw that Suzy had6her geography book to a picture of a train, and in her notebook, she had made a(n)7copy.

    I was surprised and thought that she could do something in the coming 8show. So, I took her to see the art teacher, Miss Parker, and showed her what Suzy had 9"Why, it's wonderful," said Miss Parker, who then showed us a poster she had painted10the talent show. "I need more of these, but I just don't have enough11Could you help me, Suzy?"

    On the day of the talent show, Suzy's12were everywhere—all over the hall and all over the school, each one different.

    "And finally," said Mr. Brown, the schoolmaster, at the end of the show, "we have a(n)13award. I'm sure you've all noticed the wonderful posters." Everyone nodded. "One of our own students14them."

    I could hear everyone whispering. "Who in our school could draw15well?"

    Mr. Brown waited a while before saying, "16this student worked so hard on the posters, she deserves a17 too. Our mystery(神秘) artist is our new student—Suzy Khan!"

    Mr. Brown thanked her for all the wonderful posters and gave her a professional artist's set. "Thank you," she cried.

阅读下列材料:

当今世界,无论发达国家还是发展中国家都重视“福利国家”的理论探讨和实践,因为“福利国家”建设已经成为经济发展、政治民主的标志。阅读下列材料,回答问题。

材料一:剩余型社会福利的观点认为:在通常情况下,家庭和市场是满足个人需求的自然渠道,但是当发生诸如家庭解体、较大范围内的经济萧条或者个人年老、疾病等的特殊情况下,家庭和市场就不能满足个人的正常需求,这时候就需要作为满足个人需求的第三种社会机制即社会福利制度的介入,当通常的制度恢复正常以后,社会福利制度就会撤回。

——摘编自朱燕《西方国家社会福利政策变迁及其对我国的启示》

材料二:著名经济家凯恩斯也认为:“市场在保障人类再生产上失败了。为了创造健康和幸福和生产力,人们要组织起来,以集体的形式来共同分担风险与不幸,而这个风险的分担经常是由国家来规划的,有时候通过投资的形式来完成,国家在其中充当着主要角色。”

——唐钧《社会政策:国际经验与国内实践》

材料三:我国社会养老服务体系建设……还存在着与新形势、新任务、新需求不相适应的问题,主要表现在:缺乏统筹规划,体系建设缺乏整体性和连续性;社区养老服务和养老机构床位严重不足,供需矛盾突出;设施简陋、功能单一,难以提供照料护理、医疗康复、精神慰藉等多方面服务;布局不合理,区域之间、城乡之间发展不平衡;政府投入不足,民间投资规模有限;服务队伍专业化程度不高,行业发展缺乏后劲;国家出台的优惠政策落实不到位;服务规范、行业自律和市场监督有待加强等。

——国务院办公厅关于印发社会养老服务体系建设规划(2011——2015年)的通知
