Q4 to Q6:
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 composing
the fault. Geologists’ pre-1965
assumptions concerning heat generated
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 thousands
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 wondered
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.

Q4:
The passage suggests which of the following regarding Henyey’s findings about
temperature in the San Andreas Fault?
A. Scientists have yet to formulate a definitive explanation for Henyey’s findings.
B. Recent research suggests that Henyey’s explanation for the findings should be
modified.明显错，ｈｅｎｙｅｙ没给解释只是发现。
C. Henyey’s findings had to be recalculated in light of Byerlee’s 1992 experiment.
D. Henyey’s findings provided support for an assumption long held by geologists.用老的可以解释。等于支持了老的解释，只不过后来被新的解释替换了
E. Scientists have been unable to duplicate Henyey’s findings using more recent
experimental methods.

Q6:
The passage mostly agree that Heney’s findings about temperature in the San Andreas
Fault made the greatest contribution in that they
(Note: This question main body is missing, but the answer choices are got completely. It
is simulated by my memory and will closely resemble the original question main body.)
A. revealed an error in previous measurements of temperature in the San Andreas
Fault zone 错
B. indicated the types of clay present in the rocks that form the San Andreas Fault错
C. established the superiority of a particular technique for evaluating data concerning
friction in the San Andreas Fault错
D. suggested that geologists had inaccurately assumed that giant rock plates that
meet at the San Andreas Fault generate heat through friction 没有最好只有比较好吧。其他都不对
E. confirmed geologists’ assumptions about the amount of friction generated by
common varieties of rocks, such as limestone and granite
