Q4, 一个have yet to让我理解成了已经有了定论，想想和原文表达想背，没敢选
原来是还需寻找定论，唉.....
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.

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

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
Answer:管ａ 我ｄ
这三道题目我做了第二遍，仍然无法同意官的答案。希望高手能帮我指点一下 非常感谢。
Hi, I am also studying the test of GWD. We can work it out together!!!!
As to your quesiton, I agree with you at Q5 & Q6. The answer provided by GWD must be wrong.
However, as to Q4, the answer is A. Because scientist still have to find a theory to explain why the high temp did not exit at the interface. Your answer D is not right I think. Cause H's finding did not support any previous belief (the belief is that friction did exist) but weaken the belief. What do you think?
Welcome open discussion.
我也同意第一题选a 就是当时想这个选项怎么这么奇怪，就没敢选。 谢谢。 
我认为如果选项A改为：
A. Scientists have not yet formulated a definitive explanation for Henyey’s findings.
答案就肯定是A了。
hello all,
ever think of the meaning of "yet" in choice A?
According to Oxford advanced Chinese-English dictionary :
Yet :used with a modal v:formal if placed immediately after the modal v.與清太動詞連用。 = at an indefinite time in the future. 表示不久的將來，遲早，早晚 。
如 she may surprise us all yet.
we can yet reach our destination.
因此我們 a中的 have yet to 是否 也 可以這樣理解
yet: adv. (formal) still.(Longman 88版)。example:
I have yet to find out the truth=I have still to find out the truth. 我仍需查出真相。
我的答案是GWD的套题答案，就是ABD啊？为什么你们的不是？我得答案不是管的？奇怪。
管的答案是ABD吧应该...
我觉得第一个A不对,少了not,文章意思一定是说还没有定论的
我选B,因为H人只说到了材料不同,后面的实验说了还有一种可能就是里面有水,产生反方向的力,这点是H没说到的,所以H说的应该modify
我觉得应该是B诶。。。晕哦，它没有科学家have to find a definite explanation的意思啊～～谁说一定要找个最后解释；
而B，正是henyey同学就自己的发现提出了一点点explanation，最后被recent research否啦
我觉得应该是B诶。。。晕哦，它没有科学家have to find a definite explanation的意思啊～～谁说一定要找个最后解释；
而B，正是henyey同学就自己的发现提出了一点点explanation，最后被recent research否啦
你看错啦. Henyey同学只是说他发现那个温度没原来期望的那么高...至于那些解释,是some geologists们加上去滴.
所以B不正确,因为Henyey同学说的那个结论是对的,无需修改
同意第4t选A, 如果那个yet代表需要进一步研究的话,偶刚开始也是以为管同学少key了一个not呢
第六题,我对D答案有疑问.
D:H的功绩在于他指出前人的错误假设,这个假设是"版块的热量是又摩擦产生的"
但我觉得H的解释并没有反对"版块的热量是又摩擦产生的"这个假设啊! 他发现的是热量还是由摩擦产生的,只不过由于岩石构造质地不同,使得产生热量少了.
所以我觉得D不对.
哪位帮帮我!!

不是吧，这篇文章怎么讨论的人这少啊！？
文章容易读，可是错两个，真郁闷...
HAVE YET TO FORMULATE,注意不是FORMULATED
自己想明白了,呵呵
翻译的真好
总算明白第4题为什么不选D了
好奇怪第4题大家怎么都选A呀？哪有 formulate a definitive explanation 哦！
我严重支持C ^-^ 有同志同意么？
C是怀疑Henyey’s findings有问题，需要重新计算，可是文中哪里有怀疑Henyey’s findings的地方呢？
他这个发现是没有什么人去质疑的，只是要找出解释
4 题的 C
. Henyey’s findings had to be recalculated in light of Byerlee’s 1992 experiment.
为什么错 ？
Q4, 一个have yet to让我理解成了已经有了定论，想想和原文表达想背，没敢选
原来是还需寻找定论，唉.....
同41楼问
Q4 The passage suggests which of the following regarding Henyey’s findings about
temperature in the San Andreas Fault?
C、 Henyey’s findings had to be recalculated in light of Byerlee’s 1992 experiment.
是因为Henyey’s findings 是第一段的内容，而Byerlee是再第二段才提到的吗？？
请NN们帮忙解答一下吧！

请NN们帮忙解答一下吧！
全文整体结构是先说1965年前地质学家认为摩擦热是如何如何，然后H同学的发现使一些地质学家改变观点，认为岩石的性质构成对摩擦热也有影响；1992年B同学认为压力对摩擦热也是有影响（原文L33－36就可以看出文章的写作脉络：‘in other words, pressure itself, not only the rocks’ properties, affects frictional heating’.）
从整体看，H同学的finding并没有被B同学的发现所否定，或者要做修正，所以C改变原文意思，不正确
我试试解释：
The passage suggests which of the following regarding Henyey’s findings about
temperature in the
A. Scientists have yet to formulate
怀疑少了一个NOTa definitive explanation for Henyey’s findings.
从文中可以看出科学家仍在寻找解释这种现象的理论
B. Recent research suggests that Henyey’s explanation for the findings should be
modified.H并没有解释什么，只是发现了某个现象，不存在解释的问题
C. Henyey’s findings had to be recalculated in light of Byerlee’s 1992 experiment.B反驳的是一些地理学家估计可能是因为忽略了粘土不怎么产生热量从而导致H的发现温度没有想象的那么高，而不是反驳H的发现，所以不需要重新recalculated H的发现，需要的是重新解释这个发现
D. Henyey’s findings provided support for an assumption long held by geologists.
从but就可以看出不是支持了
E. Scientists have been unable to duplicate Henyey’s findings using more recent
experimental methods.无关
From Longman Dictionary of Comtemporary English
8 sb/sth has yet to do sth formal ：used to say that someone has not done something, or that something has not happened when you think it should already have been done or have happened: •I have yet to hear Ray's version of what happened. yet本身即帶有否定意味
指出前辈的一点小错误：
“Geologists’ pre-1965
assumptions concerning heat generated
in the fault were based on 指出老观点的错误
只基于一般种类的岩石进行的计算
(15)
calculations about common varieties of
rocks, ”
这里没有明确指出老观点错误，“in the fault ”是“在断层”的意思，而非是“Fault错误的”意思。
就觉得第一题出的不好：（
也是文章容易，选项很搞
文章确实挺容易的，但是题出得挺刁钻的。
Q6 我觉得选A哦，measurement 不一定是说去测量，只是一种测算的方法，的确是用错了
另外，d的讲法是不对的，d选项 是说 “表明地质学家错误的认为两块大岩石是通过磨擦生热的“。 但实际上地质学家在岩石磨擦生热这一点上没有错，错误在于弄错了岩石的成分。 giant rock 不代表就是 limestone and granite， clay 也是可以是rock的成分，因为文章有说“rocks composed of clay produce far less friction than do other rock types“
请指正
q6选A，D是错的，同意楼上

其实正篇文章都在试图解释为什么Henyey 发现的温度比预计的要低。geologist 试图解释说是因为石头的性质不同。Some geologists wondered whether the absence of friction-generated heat could be explained by the kinds of rock composing the fault. 但是又被后来的发现否定了。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 rocks’ properties, affects frictional heating. 所以geologist 就继续其他的推理，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.
所我觉得henyey 的发现，文章到最后也没有能给出一个合理的解释。会不会这个就是在说明一开始的摩擦产生热量的假设是不对的呢？
其实我也选了A的。我觉得文章我是看懂了，但是这题还不知道怎么选。明天让老外帮我看看。
Q6
A说测量温度有错误，而文章里其实说得是assume，只是假设摩擦生热，而并没有实际去测量，就谈不上测量错了。
而D这个选项很好的指出是geologists不准确的assume,假设摩擦生热，温度高。
我举得第六题不可以选D, D的意思是，Henry对温度的测量表明以前的地质学家不准确的认为SAF是由于摩擦生热的。
但是直到文章最后，科学家们并没有改变对摩擦生热这一理论的支持。文章最后说，科学家们猜想是否是由于水压减轻了导致摩擦的压力。
所以整篇文章都没有说，摩擦生热是不对的理论， 那么这个又怎么能成为Henry发现的贡献呢？
有人争论说c选项的inaccurately不是说不准确的认为摩擦生热，而是说对摩擦生热的估计不准确。从而得出与结尾“是否是由于水压减轻了导致摩擦的压力”一致的结论。
但是我对这种看法表示怀疑。
inaccurately修饰的是动词assume，如果是"对摩擦生热的估计不准确” 则应为 The assumption is inaccurate. 形容词修饰名词。
而a选项 measurements既可以做结果讲，又可以做过程讲。
如果做过程讲，则henry的发现表明之前科学家(based on the calculations about the common varieties of rocks)测量出的温度不准确，a正确。
