解析
【分析】
这是一篇介绍美国家庭情况的阅读理解，解题时可以先浏览题干明确考点，再带着问题回到原文定位对应内容：第一题直接定位描述3人家庭占比的语句即可得到答案；第二题定位孩子离开父母家的年龄相关描述；第三题结合文章内容的客观性判断体裁；第四题梳理全文核心描述对象得出主旨；第五题先把文中给出的不同人数家庭的占比逐一整理，再和四个图表的数据逐一比对，匹配完全符合的选项即可。
【解析】
1. 原文明确提到“and another 17% have three people”，说明美国3口之家的占比是17%，对应选项A。
2. 原文直接给出“When children are about eighteen or nineteen years old, they leave their parents' homes”，可知美国孩子通常在18或19岁左右离开父母家，对应选项D。
3. 文章客观罗列了美国家庭结构的相关统计数据，属于纪实类的报道，不是旅行故事、发明介绍也不是笑话，对应选项B。
4. 全文围绕美国家庭的规模、结构特点展开介绍，核心主题是美国家庭，对应选项A。
5. 整理文中所有占比数据：1人家庭占比超过25%，2人家庭占比35%，3人家庭占比17%，4人家庭占比接近18%，5人及以上家庭占比不足10%，完全符合该数据分布的是选项A的图表。
【答案】
1.A 2.D 3.B 4.A 5.A
【知识点】
细节信息查找，主旨大意理解，图文匹配
【点评】
本题整体难度适中，多数题目可以通过直接定位原文细节快速得出答案，最后一道图表匹配题需要学生整合文中所有统计数据，逐一核对图表的数值分布，避免只看部分数据错选其他选项，能有效锻炼学生信息整合的能力。
【难度系数】
