      I climbed the ladder, heard my dive announced, and began the moves that would push me into

the air. Pushing off the diving board with my legs, I lifted my arms and shoulders back, and knew

immediately I would be close to the board and might hit my hands. I tried to correct myself as I

turned, spreading my hands wide apart. Then I heard a strange sound and my body lost control.

Moments later I realized I had hit my head on the board.

       At the beginning, I felt embarrassed. I wanted to hide, to get out of the pool without anyone

seeing me. Next I felt intense fear. Had I cut my head? Was I bleeding? Was there blood in the pool?

Swimming to the side, I noticed many shocked faces. People were worried about my head; I was

worried about something far more threatening. An official examined my head. In a hurry, I pushed

him away, and everyone else who approached me. "Don't touch me!" I felt like screaming. "Get away

from me!"

       These were the trials (选拔赛) for the 1988 Olympics in Seoul, Korea. Until this dive, I had been

ahead. But now, something else was more significant than winning. I might have endangered other

divers' lives if I had spilled blood in the pool. For what I knew--- that few others knew - was that I

was HIV-positive.

       According to my mother, my natural parents were Samoan (萨摩亚人) and only teenagers when

I was born, so they gave me up for adoption. When I was only eighteen months old, I started gym

classes. At ten, I explored doing gym exercises off the diving board at the pool.

       Because of my dark skin, kids at school called me names. My diving made me feel good about

myself when my peers made me feel stupid. At sixteen, I knew I had a shot at the 1976 Olympics.

       Everyone was alarmed when I hit my head on the board in Seoul. Regardless, I made it to the

finals. During my last dive in the finals, I enjoyed for the last time the quietness underwater and then

swam to the side of the pool. The crowd cheered, and I knew I'd won-two gold medals. AIDS

forced me to stop diving; I had to give up diving professionally after the Olympics.

单项选择题

阅读以下文字,回答下列问题。
政府在新城建设和小区规划中,都应保证书店与文化设施的足够数量。
全国两会期间,不少代表委员关注实体书店的命运,呼吁政府加大投入。2005年全国共有国有书店网点11897处,供销社网点3200处,集个体零售网点108130处,而到2009年,国有书店网点减少为9953处,供销社网点减少为1636处,集个体零售网点减少为104269处,三类网点4年就分别下降了16.34%、48.88%和3.57%。
从我们日常生活体验也可以看出上面数据的真实性,譬如社区周边的几家大超市,早前都有上百平方米的书店开设其中,现在多已让位于其他商品摊位,这种现象的根本原因是因为人们获得资讯与知识的方式正在发生变化,譬如通过手机就可以实现在线阅读。
除上述因素外,还有政府对中小书店扶持缺位的因素,政协委员张抗抗在提案中认为一些地方政府对传统书店的发展持相对消极的态度。一些国营新华书店完成了连锁模式改造后,市场化动力不足、民营书业渠道由于缺少政策扶持,在网络书店的巨大冲击下,很多都没有找到有效的发展路径。
那么,世界各国对中小书店又是如何予以政策支持的呢法国政府长期免征书店所得税;加拿大政府为独立书店购置电脑设备支付一半的费用;德国政府不仅免征书店的所得税,还在增值税上给予书店优惠;日本和韩国政府制定图书最低折扣以保护实体书店与网络书店处于平等的竞争舞台。图书阅读,不仅关乎整个国民素质,也体现政府的人文情怀。中国社会正在转型过程之中,更多的农村人口将进驻到城镇之中,在这样的过程中,政府应该主动顺应形势,无论是新城建设还是小区规划中,都要通过增加书店与文化设施数量,以体现人文关怀与对市民的文化福利回馈。
我们一方面要向其他国家学习,减免书店税负,另一方面,要实行城建达标,如果新建社区与城镇图书馆、文化场所、中小书店与所住人口不成比例,即视为不迭标。要督促相关部门追加投资,或政策扶持,特别是大型超市里,更应该通过减免税负设立书店,让书店离普通民众更近一点。
我们期待政府有更积极的作为,有新思路与新方式。在支持基层文化建设过程中,要切忌一味造大的剧场、大体育场馆,那样只会使文化高雅得远离民众。

根据本文,下列说法正确的是( )。

A.文章分析了三种实体书店中供销社网点降速最快的原因
B.文章强调在大型超市中开设实体书店有积极引导作用
C.文章阐述了中小书店的重生主要依赖于政府的政策扶持
D.作者建议我国将城市建设达标制度作为支持实体书店的新举措
