高中《物》(选修本)“绪论”部分明确提出:学习生物学相关知识,不仅是让大家了解客观世界,更重要的是让大家关注自身健康。在近几年的高考试题中,营养和疾病成了命题的“热点”之一。这种命题趋势一方面能够考查学生基本知识的掌握情况,另一方面也能考查学生灵活运用知识的能力,同时也体现了自然科学中渗透的人文关怀。综观2006年全国理综、单独命题理综及部分省市生物单科试题,关于营养和健康的知识点多有涉及,广东文理大综合第三大题提示语即为:“生命是神奇的、可贵的,也是脆弱的。我们要关爱生命。”上海理综第35题要求以“珍惜生命,安全用电”为主题设计一幅宣传画,第五大题的提示语为:“关注身体健康,提高生活质量”,包括了46～51共6个小题,因此在备考2007时大家应密切关注“营养”、“疾病”、“健康”、“生命”等“热门”话题。下面笔者通过对2006年部分相关试题的剖析,以期起到抛砖引玉的作用。
