这是一篇介绍潜泳运动的说明文阅读理解题，全部为细节理解类题型，解题思路如下：
1. 先通读题干明确每道题的提问方向，带着问题回到原文对应段落定位关键信息；
2. 每道题找到原文依据后逐一比对选项，排除和原文内容不符的错误选项，选出正确答案；
3. 第12题是选错误表述的题型，需要先把三个符合原文的正确选项排除，剩下的就是不符合题干要求的错误项。
【解析】
逐题对应原文分析：
9. 定位原文第一段内容，可知潜泳描述的“像去月球”只是比喻，实际这项运动是带你进入水下的全新世界，结合第三段提到的可以在深水区长时间停留，可知潜泳会带你去到深水区，B选项山脉、C选项陆地新世界完全不符合，D选项只是比喻并非真的抵达月球，因此选A。
10. 定位原文第一段最后一句“When you are under the water, it is easy for you to climb big rocks, because you are no longer heavy.”，说明在水下你的体重比在陆地上轻，所以能轻松攀爬大石头，A说很重、B说和陆地一样重、C说你很瘦都不符合原文表述，因此选D。
11. 定位原文第三段第一句“When you have tanks of air on your back, you can stay in deep water for a long time.”，内容直接对应B选项，其余选项都不是背负空气罐的专属作用，因此选B。
12. 逐一核对选项：A选项“潜泳是一项新运动”对应原文开篇第一句表述正确；C选项“潜泳就像游览月球”对应原文第一段比喻内容表述正确；D选项“潜泳不仅有趣还实用”对应原文最后一句表述正确；B选项“潜泳唯一的用途是获得更多乐趣”和原文第四段提到的潜泳还有很多其他实用用途的内容矛盾，是错误表述，本题要求选出不正确的选项，因此选B。
