材料一:我国已经进入老龄化社会,我国老年人口基数非常庞大,养老成为一大社会问题,在如何养老的问题上,我们一直在不断地探索,探索出了“医养结合”模式,实现“老有所依”。随着我国经济社会的不断发展,在社会层面,社会为老年人提供了医疗保险和养老保险,由社会为养老 “托底”;在个人层面,现在老年人与传统老年人对养老的追求和愿景发生了较大的变化,现在的老年人对养老的“质量”要求比较高,现在老年人手中的“财富”比传统老年人更足。而“医养结合”,正是迎合老年人对养老的需求,打开养老服务和医疗服务之间的双向通道,实现“1+1>2”的最大化利用效果“十三五”期间将推进健康中国建设,随着各方纷纷布局,医养结合产业将在不久的将来迎来爆发式增长机会。

材料二:近年来,浙江省政府在统筹城乡发展方面采取了一系列措施。在经济上,着力改变传统工业层次低、布局散、竞争力弱的状况,推进新兴产业,发展现代农业,培育各类专业市场,加大对“三农”的财政投入和转移支付的力度,推进农村住房改造和城镇化建设,力推“家电下乡”,建立和健全城乡居民社会保障制度等。在文化上,实施农村文化基础设施建设、农村电影放映“2131”、送戏送书下农村、广播电视“村村通”等一系列文化工程,推进农村文化建设。

    I was shopping in the supermarket when I heard a young voice.

    “Mom,come here!There's this lady here my size!”

    The mother rushed to her son;then she turned to me to apologize. I smiled and told her,“It's okay.”

    Then I talked to the boy,“Hi,I'm Darryl Kramer. How are you?”

    He studied me from head to toe,and asked,“Are you a little mommy?”

    “Yes,I have a son,” I answered.

    “Why are you so little?” he asked. “It's the way I was born,”I said.“ Some people are little. Some are tall. I'm just not going to grow any bigger.” After I answered his other questions,I shook the boy's hand and left.

My life as a little person is filled with stories like that. I enjoy talking to children and explaining why I look different from their parents.

    It takes only one glance to see my uniqueness. I stand three feet nine inches tall .I was born an achondroplasia dwarf(侏儒).Despite this,I did all the things other kids did when I was growing up.

    I didn't realize how short I was until I started school. Some kids picked on me,calling me names. Then I knew. I began to hate the first day of school each year. New students would always stare at me as I struggled to climb the school bus stairs.

    But I learned to smile and accept the fact that I was going to be noticed my whole life. I decided to make my uniqueness an advantage rather than a disadvantage. What I lacked in height,I made up for in personality.

    I'm 47 now,and the stares have not diminished as I've grown older. People are amazed when they see me driving. I try to keep a good attitude. When people are rude,I remind myself,“Look what else I have-a great family,nice friends.”

    It's the children's questions that make my life special. I enjoy answering their questions. My hope is that I will encourage them to accept their peers(a person of the same age,class,position,etc.),whatever size and shape they come in,and treat them with respect.
