13、明。此项运动针对失明的四个主要原因。白内障使眼睛晶状体变浑浊。在非洲和亚洲的大部分地区，由白内障引起的失明至少有一半可治愈。一个简单的手术就可以清除白内障。沙眼是一种人与人或通过昆虫传播的传染病。在所有失明病例中约有15%是由沙眼造成的。这种病例大部分发生在非洲，可以通过服用抗生素药物治愈，也可通过手术治愈。据称在非洲还发现了一种河流失明的眼病。飞蝇是其传播途径。服用一年异凡曼霉素就可以控制这种疾病。最后，由于营养不良而缺乏维生素A是造成孩子可预防性失明的主要原因。“2020年健康视力”运动宣称，世界上每五秒就有一人失明，大部分失明者生活在发展中国家。印度至少有九百万失明者，中国约有六百万，非
14、洲约七百万。官方估计，为了治愈失明，每年世界经济损失约280亿美元。于5月召开的世界卫生大会通过了一项决议，此决议敦促各国政府制定全国性计划来防止失明。您还可以通过登陆v2020.org网站了解更多有关“2020年健康视力”的信息。本篇美国之音特别英语发展报道由吉尔莫斯撰稿，菲斯罗伯茨报道。答案：I. 1. by 2020 2. blindness can be cured or avoided 3. cause at least half the cases of blindness 4. also found mostly in Africa 5. estimate that the world economyII. 1.
