求牛牛指导这种题型该怎么做？

就是问你这篇文章主要说什么，类似：The passage is primarily concerned with

我整篇文章都知道什么意思，其他题目都做对，就是碰到这种题型就错，不知道有没有人克服这类问题的。




举个例子：


Prior to 1965 geologists assumed
that the two giant rock plates meeting at
the San Andreas Fault generate heat
Line through friction as they grind past each
(5) other, but in 1965 Henyey found that
temperatures in drill holes near the
fault were not as elevated as had
been expected. Some geologists
wondered whether the absence of
(10) friction-generated heat could be
explained by the kinds of rock com-
posing the fault. Geologists’ pre-1965
assumptions concerning heat gen-
erated in the fault were based on
(15) calculations about common varieties of
rocks, such as limestone and granite;
but “weaker” materials, such as clays,
had already been identified in samples
retrieved from the fault zone. Under
(20) normal conditions, rocks composed of
clay produce far less friction than do
other rock types.
In 1992 Byerlee tested whether
these materials would produce friction
(25) 10 to 15 kilometers below the Earth’s
surface. Byerlee found that when clay
samples were subjected to the thou-
sands of atmospheres of pressure
they would encounter deep inside the
(30) Earth, they produced as much friction
as was produced by other rock types.
The harder rocks push against each
other, the hotter they become; in other
words, pressure itself, not only the
(35) rocks’ properties, affects frictional
heating. Geologists therefore won-
dered whether the friction between the
plates was being reduced by pockets
of pressurized water within the fault that
push the plates away from each other



1.The passage is primarily concerned with

A.evaluating a method used to test a particular scientific hypothesis
B.discussing explanations for an unexpected scientific finding
C.examining the assumptions underlying a particular experiment
D.questioning the validity of a scientific finding
E.presenting evidence to support a recent scientific hypothesis

首先，先判断文章的类型，读了第一段之后可以确定，此文为新老观点型其次，确定文章的TOPIC SENTENCE.在GMA ...

+1！！！！！！！！！！！！！！！！！！！！！！！

非常感谢！主要我在做的时候没有找到关键句与之对应 所以一直在选项间徘徊

据说新东方有些可以看题不用看文章的办法，可行吗？

BULL SHIT!!!!!!!!!!!!!!!!!!

首先，先判断文章的类型，
读了第一段之后可以确定，此文为新老观点型

其次，确定文章的TOPIC SENTENCE.
在GMAT的阅读中，文章的起承转合非常重要，主要体现在however, but, yet, although  这四个词上
But 在两个地方需要警觉

1. 出现在一段之首，说明这一段有历史性大转折，和前段所讲的内容完全不是一个范畴，比如一个全新的观点，本文符合此规律

but in 1965 Henyey found that
temperatures in drill holes near the
fault were not as elevated as had
been expected.


为本文的TS(TOPIC SENTENCE)

即解答了.The passage is primarily concerned with
B.discussing explanations for an unexpected scientific finding
（but in 1965 Henyey found that temperatures in drill holes near the fault were not as elevated as had been expected.的同意替换）

抓住文章逻辑框架

观点：1965年以前，地理学家们假设两块巨大的岩石版块在SAF相遇，并摩擦中生热

发现：H发现在SAF边的温度并没有预期中的高

于是，引出第一种解释：因为有CLAY的存在，温度不够高

第二种解释：压力解释说

这样这几考题都明了了啊！

不可行，我不建议~

嗯，您这么一说，好像就是了，有时候会不会经常在两个答案之间徘徊？如果是在两个答案之间不确定，有没有什么好方法？

这样的话应该要分情况了，毕竟可能是理解不到位，也有可能是选项比较模糊。
