参考答案
正确答案：B
细节题。题目问的是：儿童更易患感冒的原因是什么?用题干信息词Children，morecolds定位到原文第二段倒数第三句，这里直接提出了这个问题：Whydokidsseemsomuchmoreeasilytogetcoldsthantheirparents?紧接着后面两句讲到了原因：Simple．Theyhaven’thadtheopportunitytobecomeimmunetomanycoldviruses．对比分析原文和题目，本段开头就讲到儿童易患感冒，原文说的是，原因很简单，儿童不可能对多种感冒病毒都具有免疫能力(haven’t…immunetomanycoldviruses)，B选项中的notimmunetomanycoldviruses和原文表达的意思一致。所以本题答案为B选项。
