　　以下将为正在备战GMAT考试的同学们整理一些经典的GMAT阅读试题，并分多个合集推出，希望能够为正在备考GMAT考试的考生提供或多或少的帮助。

　　GWD-7-Q22:

　　The passage is primarily concerned with discussing

　　A. the composition of Earth’s mantle

　　B. how the Hawaiian Islands were created

　　C. what causes Earth’s surface plates to move

　　D. two different mechanisms by which volcanoes are formed

　　E. why most volcanoes occur at plate boundaries

　　--------------------------------------------------------------------------------

　　GWD-7-Q23:

　　It can be inferred from the passage that a chain of volcanoes created by a mantle plume would most likely be characterized by

　　A. a curved outline

　　B. constituent volcanoes that differ from each other in age

　　C. occurrence near a plate boundary where one plate bends under another

　　D. appearance near many other volcanic chains无

　　E. rocks with a wide range of chemical composition

　　Because the source of a hot spot remains fixed while a surface plate moves over it, over a long period of time an active plume creates a chain of volcanoes or volcanic islands, a track marking the position of the plume relative to the moving plate. f

　　--------------------------------------------------------------------------------

　　GWD-7-Q24:

　　The author’s rerence to the Hawaiian Islands serves primarily to

　　A. provide an example of a type of volcanic activity that does not occur elsewhere

　　B. identify the evidence initially used to establish that the Pacific plate moves

　　C. call into question a theory about the source of the volcanoes that created the Hawaiian Islands

　　D. illustrate the distance from plate edges at which volcanoes typically appear

　　E. provide an example of how mantle plumes manifest themselves on Earth’s surface

　　The natural history of the Hawaiian island chain clearly shows the movement of the Pacific plate over a fixed plume.

　　--------------------------------------------------------------------------------

　　GWD-7-Q25:

　　According to the passage, a hot spot on Earth’s surface is an indication of which of the following?

　　A. An untapped reservoir of hot rock in the base of the mantle

　　B. Volcanic activity at the edge of a plate

　　C. Solid mantle rock under tremendous pressure

　　D. The occurrence of a phenomenon unique to the Pacific plate

　　E. A plume of hot mantle rock originating near Earth’s core

　　Because of its proximity to Earth’s core, the rock at the base of the mantle is much hotter than rock in the upper mantle.

　　The surface mark of an established plume is a hot spot—an isolated region of volcanoes and uplifted terrain located far from the edge of a surface plate.
