题型分类：主旨题

题干分析：对话主旨。

原文定位：

Right. Well, one of those articles was a real surprise. Apparently, there's this guy, an artist, who builds underwater sculpture parks. His name is Jason deCaires Taylor. Jason deCaires Taylor, this artist, he makes sculptures and installs them at the bottom of the ocean near coastlines. The article said he's created over 900 sculptures so far.

选项分析：文章首先提到学生在写与海洋酸化相关的论文，随后便提到学生在网络上搜索相关的内容，并找到了写Taylor的雕塑的一篇文章，随后整篇文章都在围绕着这个话题展开，可知应选 D选项。文章主要讲如何通过水下雕塑保护珊瑚礁，A选项错误；B、C选项未提及。
