GMAT机经是指GMAT考生对GMAT考试的总结和试题的回忆。可以说GMAT机经是GMAT考试真题的再现。很多考生都将机经作为备考资料之一，正确使用GMAT机经对于GMAT考生来说是很有帮助的。下面，楷维留学小编为GMAT考生分享GMAT5月阅读机经:有关庙宇建造时间度量的内容。

　　GMAT5月阅读机经:有关庙宇建造时间度量【本月原始】

　　总体：讲了度量temple的方法

　　(1)认为建造的时间是30年，而非250年

　　(2)历史学家没法度量时间，最新发现一种方法，根据coral来判断时间。----怎么用coral来判断

　　(3)最后判断出temple时间

　　类似于OG那篇海底同位素判断时间变化的结构。

　　原文：Proto-historic Hawaiian temples on the island of Maui may have mushroomed up within just 30 years, not 250 as previously supposed, scientists say. The findings could significantly alter researchers' understanding of the pace of precontact sociopolitical change in the Pacific.

　　Hawaiian genealogies and oral histories hold that sometime around 1600 A.D. a ruler named Pi'ilani united two opposing chiefdoms on Maui into a peaceful kingdom, marking the emergence of a religious state on the island. Archaeologists had been unable to confirm that sequence of events, however, in part because of the limitations of carbon dating. (一种炭14元素测时间技术)

　　In the new work, Patrick V. Kirch and Warren D. Sharp of the University of California and Berkeley used another kind of radiometric technique involving thorium-230, rather than carbon-14, to date bits of branch coral that were collected from living reefs and left as divine offerings at seven different temples during construction.(部分细节定位题) Dates for these corals, which had been incorporated into walls and platform fill, all fell in a narrow range of 1565 to 1638 A.D., give or take a few years on either end. Moreover, dates on the samples that best reflect the time they were harvested from the sea--those from the coral branch tips--ranged from 1608 to 1638 A.D., an interval of just 30 years. These findings thus point to intensive temple-building during that time. Because temples served as centers for control of production and the collection of surplus goods, the team contends, it seems likely that the construction boom accompanied a profound shift in sociopolitical structure. (第二段有细节题，看仔细)

　　Kirch and Sharp observe that the conquests described by local oral traditions coincide with these new dates, and would have more than doubled the size of the Maui polity to upwards of 2,360 square kilometers--the magnitude of expansion expected with the formation of an archaic state. "The temples provide tangible archaeological evidence of the speed with which a fundamental sociopolitical transition occurred in proto-historic Hawaii," the authors conclude. Indeed, they note, it may have happened in the span of a single generation of Hawaiians. (证明夏威夷社会政治的发展比预想快，在一代就完成)

　　Q1:TOPIC证明夏威夷社会政治的发展比预想快 topicQ2: What can infer EXCEPT (细节题)Q3: why scientist can not prove Hawaii happened in a single period of history originally?: the limitations of carbon dating.

　　Q1：为什么作者最后一句话提到判断出 temple 的建造时间是 a single generation?

　　用于表明结论和历史学家们认为的不同(V 35)

　　Q2：本文中提供的信息不能得到以下哪个选项的答案，选项中有：为什么科学家认为是250年?用coral检验了什么?等等
