2011新gre考试实施以来，参加了新版gre考试的考生都觉得阅读部分的题难度增加了，这主要是由于新gre考试逻辑阅读需要考生的逻辑反应一定要比以前更快，可能考生还是有点不习惯，或是没有准备充足。那么，接下来的几天，小编将给大家搜索整理一些新gre考试逻辑阅读的练习题，希望考生能从平日的练习中总结规律，找到解题技巧。

　　Eight percent of the Earth‘s crust is aluminum, and

　　there are hundreds of aluminum-bearing minerals and

　　vast quantities of the rocks that contain them. The best

　　aluminum ore is bauxite, dined as aggregates of alumi-

　　5 nous minerals, more or less impure, in which aluminum

　　is present as hydrated oxides. Bauxite is the richest of all

　　those aluminous rocks that occur in large quantities, and

　　it yields alumina, the intermediate product required for

　　the production of aluminum. Alumina also occurs natu-

　　10 rally as the mineral corundum, but corundum is not

　　found in large deposits of high purity, and therore it is

　　an impractical source for making aluminum. Most of the

　　many abundant nonbauxite aluminous minerals are

　　silicates, and, like all silicate minerals, they are

　　15 rractory, resistant to analysis, and extremely difficult to

　　process. The aluminum silicates are therore generally

　　unsuitable alternatives to bauxite because considerably

　　more energy is required to extract alumina from them.

　　□A Are aluminum-bearing nonbauxite minerals plentiful?

　　□B Do the aluminous minerals found in bauxite contain hydrated oxides?

　　□C Are aluminous hydrated oxides found in rocks?

　　6. The author implies that corundum would be used to produce aluminum if

　　(A) corundum could be found that is not contami-nated by silicates

　　(B) the production of alumina could be eliminated as an intermediate step in manufacturing alu-minum

　　(C) many large deposits of very high quality corun-dum were to be discovered

　　(D) new technologies were to make it possible to convert corundum to a silicate

　　(E) manufacturers were to realize that the world‘s supply of bauxite is not unlimited

答案：C/ABC/C

　　以上即是阅读练习题，对于新gre考试逻辑阅读，考生除了采取题海战术，其实更应该做的就是总结。如果能从平日的练习中找到解新gre考试逻辑阅读题的思路，那么，要比采取题海战术更好。
