6．The World Health Organization （WHO） planned to study the relationship between the eating habits of the people and the disease．Two doctors were chosen to make the study．They flew to Africa south of the Sahara and during the next two months visited ten countries．They found that serious diseases of poor eating，often mistaken for other diseases，existed in all parts of Africa．The diseases were similar and could therefore all be named kwashiorkor．The diseased children are usually from one to four years old．As the illness progresses，the child's stomach becomes swollen by liquid collecting in the body．The skin changes color and may break out in open sores（疼痛）．The hair changes color and starts to fall out．The patient loses all interest in his surroundings and even in food，and becomes so weak that he wants to lie down all the time．Stomach liquids are no longer produced．
The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat．Their mothers，after stopping their breastfeeding，gave them foods full of starches（淀粉）instead of greatly needed proteins．They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives．
The unbelievable thing about kwashiorkor is that the very existence of the disease-which has been killing thousands of children for centuries-was not even recognized in Latin America as recently as ten years ago．The deaths of those children were mistakenly listed as due to other diseases．It was the WHO's work in Africa that led to the discovery of the problem in Central America．

A．poor living conditions

解答 62-65 BDCB
62．B细节理解题．从第二段的句子：The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat．Their mothers，after stopping their breastfeeding，gave them foods full of starches（淀粉）instead of greatly needed proteins．可知医生推断，在非洲许多地区的儿童都患有夸休可尔症，其原因是缺乏乳品或肉品．他们的母亲停止母乳喂养后，用淀粉类的食物来代替蛋白质．由此可知，kwashiorkor这种病是由于食品中缺乏蛋白质造成的．故选B．
63．D细节判断题．从第一段的句子：They found that serious diseases of poor eating，often mistaken for other diseases，existed in all parts of Africa．The diseases were similar and could therefore all be named kwashiorkor．可知他们发现这种由不好的饮食导致的严重疾病，经常被误认为是其他疾病，而在非洲各地都存在这种疾病，它们之间很相似．由此可知，kwashiorkor很难被发现因为他的症状和其他的病没什么不同．故选D．
64．C细节理解题．从第二段的句子：They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives．可知治疗这个病的简单的方法是在食物中增加更多的肉和牛奶．故选C．
65．B标题确定题．这篇文章讲的是因为饮食不适当引起kwashiorkor这种疾病，所以Kwashiorkor and Improper Eating Habits是最恰当的标题．故选B．
点评 阅读这类文章时，也应该在整体把握文章结构的前提下，主要注意细节信息．细节题题干都是相应原文的变形（如同义改写、词性转换等），因此要找到答案一定要找到题干在原文中的出处，再把原文和选项相比较．做题时，根据所提问题用寻读、跳读的方法可达到事半功倍的效果．
