called pillow lava. This rapid chilling occurs when lava erupts
directly into water (or beneath ice) or when it flows across a
shoreline and into a body of water. While the term ―pillow lava‖
suggests a definite shape, in fact geologists disagree. Some
geologists argue that pillow lava is characterized by discrete,
ellipsoidal masses. Others describe pillow lava as a tangled
mass of cylindrical, interconnected flow lobes. Much of this
controversy probably results from unwarranted extrapolations
of the original configuration of pillow flows from two-
dimensional cross sections of eroded pillows in land
outcroppings. Virtually any cross section cut through a tangled
mass of interconnected flow lobes would give the appearance
of a pile of discrete ellipsoidal masses. Adequate three-
dimensional images of intact pillows are essential for defining
the true geometry of pillowed flows and thus ascertaining their
mode of origin. Indeed, the term ―"pillow",itself suggestive of
discrete masses, is probably a misnomer.
这是36套里面section17的第一篇阅读,当时做的时候就感觉对文章理解的不好,这篇后面的三道题就对了一道,后来仔细看了看还是不太理解这篇文章的结构,所以请大家帮忙一起来讨论讨论这篇的结构啦,非常感谢~~~ 作者: huangtan 时间: 2013-8-18 15:27
Volcanic rock that forms as fluid lava chills rapidly is
called pillow lava. This rapid chilling occurs when lava erupts
directly into water (or beneath ice) or when it flows across a
shoreline and into a body of water. (这些引出话题,知道“pillow lava”就可以了)
While the term ―pillow lava‖
suggests a definite shape, in fact geologists disagree.(说明有两派观点)
Some geologists argue that pillow lava is characterized by discrete,
ellipsoidal masses. Others describe pillow lava as a tangled
mass of cylindrical, interconnected flow lobes. Much of this

of the original configuration of pillow flows from two-
dimensional cross sections of eroded pillows in land

mass of interconnected flow lobes would give the appearance

希望对你有帮助
谢谢!!这样一来就清楚多了只是我也觉得在文章最后作者否定了第一种观点,那为什么这道题
1. In the passage, the author is primarily interested in
(A) analyzing the source of a scientific controversy
(B) criticizing some geologists‘ methodology
(C) pointing out the flaws in a geological study
(D) proposing a new theory to explain existing
scientific evidence
(E) describing a physical phenomenon
While the term “pillow lava”
选的是A而不是C呢,不是最后指出观点的缺陷了吗?作者: huangtan 时间: 2013-8-18 15:41
