【分析】
这是一篇信息类阅读理解题，解题时可以先浏览3道题的题干，划出每道题的关键词，再带着关键词回到原文对应段落定位，直接查找匹配的信息即可得出答案：第1题抓关键词get to the city centre、by metro找交通相关段落，第2题抓关键词Maxland找购物相关段落，第3题是主旨题，直接看文章首尾的总起总结句就能快速确定核心主旨，不需要复杂推理。
【解析】
1. 定位到原文交通部分的最后一句"It takes only half an hour to get to the city centre by metro."，可知乘坐地铁到市中心只需要半小时，对应选项A，B选项20分钟、C选项50分钟均和原文内容不符。
2. 定位到原文购物部分的最后一句"You can buy things, have big meals and see films there."，可知人们可以在Maxland吃大餐，选项A游泳、选项C露营均未在原文提及，因此选B。
3. 文章开篇第一句就点明核心主题"Nowadays, there are great changes in Luting District."，全文从交通、购物两个维度介绍芦汀区的变化，选项A提到的新公园完全没有在文中出现，选项C只是过去街道的局部细节，不是作者想要传递的核心内容，因此选B。
【知识点】
阅读理解细节定位，主旨大意归纳，文本信息匹配
【点评】
本题属于低难度的基础阅读题，所有正确答案都能在原文直接找到对应依据，没有设置干扰性强的迷惑选项，主要考察学生的基础文本信息提取能力，提醒同学们做主旨类阅读题时不要把局部细节当成全文的核心主题，要优先关注文章首尾的总起句快速把握主旨。
