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 |
