分析 这篇短文分为三个段落：第一段列举了科学家研究了人们每天要吃的食物；第二段讲述了不同国家的人们饮食习惯和饮食结构等各方面有很大差异．但这些对人来说都没不是很重要的，重要的是每天吃什么．第三段阐述了两个问题：如何解决世界人口的吃饭问题，既要吃饱，又要吃得健康．
解答 25．A．细节判断题．根据文章第一段中科学家所提供的人们每天必须的7类食品，可知作为午饭最健康的食品是A，故选A．
26．D．细节理解题．根据Paragraph 2的内容尤其是The important thing is what you eat every day．可知，人们每天吃几餐不重要；在哪个时间进食不重要；吃生的或熟的、罐装的或冷冻的食品不重要，重要的是人们必须吃到这七类食品的每一种．故选D．
27．D．细节理解题．根据Paragraph 2的People in different countries and different places of the world eatdifferent kinds of things．Foods are cooked and eaten in many different kindsof ways．可知，不同的国家和地区，人们进食的方法也不一样．故选D．
28．C．细节理解题．在 Paragraph 3里要解决的二个问题之一就是 find some ways to feed the world's population sothat no one is hungry找到解决饥饿问题的方法．所以C项说法是错误的．故选C．
