三、新情境 科普知识 你听说过“生长痛”吗？阅读文章，选出最佳答案。
Do you know growing pains(疼痛)? Growing pains aren't a disease(疾病). Sometimes you don't have to go to see the doctor. Usually children can get them between the ages of 3 and 5 or 8 and 12. When children are over fifteen, most of them don't get growing pains. Children often get growing pains in their legs. Growing pains often start before bedtime and sometimes in the middle of the night. But they go away by the morning. Doctors don't know why. They think when children run, climb or jump a lot during the day, they may have pains in their legs at night.

【分析】
这是一篇介绍“生长痛”的科普类阅读理解题，解题时首先可以先快速通读全文，理清文章核心是围绕生长痛的定义、易发人群、发作特点、缓解方法展开的。之后逐题划出题干关键词，带着问题回到原文定位对应语句，将选项内容和原文信息逐一比对：细节题直接匹配原文内容排除错误选项，词义猜测题结合上下文语境推导词义，主旨大意题抓住全文核心论述对象选出最贴合的标题即可。
【解析】
1. 细节理解题。根据原文第一段"Usually children can get them between the ages of 3 and 5 or 8 and 12. When children are over fifteen, most of them don't get growing pains."可知，生长痛的高发年龄段是3-5岁或者8-12岁，超过15岁基本不会出现。选项A的2岁、B的6岁、D的18岁都不在高发区间，只有10岁属于8-12岁的高发范围，因此选C。
2. 细节理解题。根据原文第一段"Children often get growing pains in their legs."可知孩子们的生长痛通常出现在腿部，对应选项D。
3. 细节理解题。逐一比对选项：A选项原文明确提到吃药对有生长痛的孩子不好，有提及；B选项原文只提到可以按摩疼痛的腿部，完全没有介绍按摩的具体方式方法，属于未提及内容；C选项文章列出了三条缓解生长痛的建议，有提及；D选项原文提到生长痛经常在睡前、有时在半夜发作，对应孩子夜间睡觉时可能出现生长痛，有提及。因此选B。
4. 词义猜测题。划线单词stretch后补充说明“像在体育课上做的动作”，结合宾语是legs（腿），体育课上对应的腿部动作就是伸展腿部，因此stretch的中文含义是“伸展”，选A。
5. 主旨大意题。全文从什么是生长痛、生长痛的易发人群、发作特点、缓解方法多个维度展开，核心论述对象就是儿童的生长痛，因此最佳标题是B选项。
