问题 The author believes that ______.
The passage is mainly about ______.

选项 A、the features of volcanic activities
B、the importance of the theory about drifting plates
C、the significance of hot spots in geophysical studies
D、the process of the formation of volcanoes

答案C

解析这是一道中心大意概括题。本篇论述的主题是什么?根据文章各段的内容，不难看出全文的主题。本篇开头作者介绍了分布于地球内部、被科学家称之为"热点"的火山活动区，并阐述了板块漂移对它们的影响。第二段中，作者又通过与大陆漂移理论的对比，说明热点理论对于理解板块与地球内部之间的运动具有重要的意义。在文章末段，作者则较为详尽地阐述了热点对海洋形成的影响。上述三段内容充分论证了热点对于地质学研究具有极为重要的意义这一主题。故答案选项是确切的；其他选项都有失片面或偏离了文章主题。
