关于中国人测量喜马拉雅山
做到了GWD的原题
我做的是TN24套的本版，Q32-35，一模一样！！连题也一样！31套的话应该是GWD27，题号一样
In 1975 Chinese survey teams remeasured Mount Everest, the highest of the Himalayan mountains. Like the Britishin 1852, they used the age-old technique of “carrying in” sea level: surveyorsmarched inland from the coast for thousands of miles, stopping at increments ofas little as a few feet to measure their elevation, and marking each incrementwith two poles. To measure the difference in elevation between poles, surveyorsused an optical level—a telescope on a level base—placed halfway between thepoles. They sighted each pole, reading off measurements that were then used tocalculate the change in elevation over each increment. In sight of the peaksthe used theodolites telescopes for measuring vertical and horizontal angles—todetermine the elevation of the summit.
TheChinese, however, made forts to correct for the errors that had plagued theBritish. One source of error is rraction, the bendingof light beams as they pass through air layers of different temperature andpressure. Because light traveling down from a summit passes through many suchlayers, a surveyor could sight a mirage rather than the peak itself. To reducerraction errors, the Chinese team carried in sea level to within five totwelve miles of Everest’s summit, decreasing the amount of air that lightpassed through on its way to their theodolites. The Chinese also launchedweather balloons near their theodolites to measure atmospheric temperature andpressure changes to better estimate rraction errors. Another hurdle is thepeak’s shape. When surveyors sight the summit, there is a risk they might notall measure the same point. In 1975 the Chinese installed the first surveybeacon on Everest, a red rlector visible through a theodolite for ten miles,as a rerence point. One more source of error is the unevenness of sea level.The British assumed that carrying in sea level would extend an imaginary linrom the shore along Earth’s curve to a point beneath the Himalaya.In reality, sea level varies according to the irregular interior of the planet.The Chinese used a gravity meter to correct for local deviations in sea level.
Q32: It can be inferred from the passage that rraction would be most likely to cause errors in measurements of a mountain’s elevation under which of the following conditions?
A. When there are local variations in sea level
B. When light passes through humid air
C. When theodolites are used relatively far from the mountain peak.(由旧版答案D改为新版答案C)
D. When weather balloons indicate low air temperature and pressure.
E. When sea level has been carried in to within five to twelve miles of the summit.
------------------------------------------------------------------
Q33: Which of the following best describes the purpose of the sentence in lines 23-25 (“The Chinese…the British”)?
A. Introduce a dinition
B. Signal a transition in focus
C. Summarize the p‘，receding paragraph
D. Draw a contrast between two different theories.
E. Present information that contradicts the preceding paragraph.
Q34: Which of the following is NOT mentioned as a possible source of error in surveying mountain elevation?
A. Mirages
B. Rraction
C. Inaccurate instruments
D. Variations in sea level
E. Uncertainty about the exact point to be measured
---------------------------------------------------------------
Q35: The primary purpose of the passage is to
A. provide details about improvements to a process
B. challenge the assumptions underlying a new method
C. criticize the way in which a failed project was carried out
D. call for new methods to solve an existing problem
E. explain the theory behind a new technique
官方答案是CBCA

多了一道说中国的方法和英国相比有啥不同 用的工具一样么？添了什么新的method？这都是选项里面的

说地震的，就2段。 第一段，说传统中广大淫民认为地震发生在浅层靠近地幔30mile的地方，然后具体说了下是怎么样发生的，是个神马样子的。第二段，就Yet开头鸟，说有地震时400mile以下的鸟，提供2个概念的对比，一个是上面的那种什么mechanism，另外一种是新的一种mechanism。第一种慢，由热力和压力共同作用于石头结构，最后引起crystal structure的崩裂；第二种快，不仅仅限于low pressure，可以一下子就搞定它的crystal structure。
问题有：1。。。。忘记鸟。
2， 第二段是什么作用：我选的是提供exception of the theory mentioned in the first passage。3，那2个mechanism的相关比较：选他们都摧残了crystal structure。

第一段说大部分地震都是浅层的，然后将浅层地震时怎么产生的，由于深处压力太大，所以没法达到地震的条件。
第二段说，其实有很多地震都是深层的。然后提出两个理论解释深层地震。第一个理论提到压力下结构变化会让物质A变成物质A&apos（名字忘了），第二个理论，对此进行补充，说物质A变成物质A&apos的过程太慢，不足以形成地震的必须条件，所以应该是物质B的结构变化，变成B&apos。（问题：大意是物质A&apos和B&apos的共同点？自然就是他们的结构都改变过）

一个地震的。第一段说以前认为地震都是由于近地面的岩石活动造成的……第二段转折了，说也有很多是由于地名一下很深的某种XX地质活动造成的，详细讲了两种XX效应，名字n长，忘了（有题比较这两者）。

说地震的，一般地震都是发生在100miles deepth以内，但是还有的发生在100miles以外。然后科学家给了两种解释，第一种是说，地下的压力和温度很大，导致100miles以外的那些crystalized成分变成固体。但是有人说了，这种变化很缓慢，不会导致灾难性的地震。然后那个科学家又提出一个理论，说虽然没有变成固体，但是他们会震动，导致震动传递。
我的理解是这样的，大家别太信了，知道这么个事情。我怕我的理解会有偏差，误导大家

题目：(不按顺序的)
1.写法主旨题
2.高亮整个第二段，问第二段在干嘛。这题楼主用的排除法，选了一个带exception的选项，有一个选项挺迷惑的，因为它的叙述基本跟上面那个写法主旨题一样，神马alternative的，但是它出现了一个词叫phenomena，于是lz果断排除了。。
3.问关于p型地震（浅层的）和m型地震（深的）下面哪个是对的 有个选项有点迷惑说他们都在400km以内 lz犹豫了一哈字还是选了结构改变那个
V6 【by: 谢家树 750】11.6日
狗狗已经说的非常详细了，我补充下题目，第一个主旨题，选解决了一个长久存在的科学疑团；第二题问第二段作用，我选提出了对第一段的一个地震理论的特例；三是问深源地震两种形成机制的共同点，就是都摧残了一个晶体结构。

还有一篇讲地震的，一开始说大家认为地震不是发生在地表附近的，但观察发现很多都是在地表不远的。第二段讲很深的地方也有几百次地震，之类之类……我根本就没看懂这两段的逻辑关系，但是有考。
V2 Bytknicole
也碰到了地震的那道题
有问说main purpose是什么
还有一道是关于什么temperture和地震formation, level还有speed有关的细节题。
V3 byjessie1004(750)
earthquake里面有考到第二段里说到的两种方法共同点是什么，我貌似选的是E，有一个迷惑选项觉得不对，是说两个都说明earquake不早于400米以下发生，距离可能不对，但是文中第一段是说old idea earthquake都在surface发生，第二段开头只说发现了在200-400米，就是比较深的地方有earthquake，但是没说400以下就不会发生，大家考场在注意一下，还考了主题题，选的应该是解释了一个scientific puzzle???忘记了
V4 by1234567x(Q51 V39)
还有一篇短的是地震的
这篇有狗的话很容易，主旨题选对一个老观点提出新观点。就是第一段说原来认为只有浅层地震，第二段说也有深层地震。
还有一个题目问第二段的，某人提出的两种解释有什么特点，选两种解释都说了是crystal line structure改变（原文是解释1是那个被否的，因为develop慢；解释2是那个被接受的）
考古(已确认) 感谢口耐的忽然
V5
地震一般人认为地震发生在地表，但实际上有hundreds of地震发生在地球深处，然后解释可能的原因，先说了一种，但认为这个过程太慢，又说了一个最有可能的原因
V 6
一个就是OG11里面有的地震有浅层的，有深层发生的。但是注意不是原文，第一段一样，但是第二段完全不同。主要问了几个全局题，比如main purpose，我选的explain a scientific puzzle，不知道是否对。
V7
另一篇是地震的那个，第一段说地震一般发生在离地表很近的地方（30？不记得单位了），第二段说有一些发生在地下150-160，然后某科学家有2个说法（那两个词我都不认识，一个是p开头的，另一个是m开头的，好像）问题有一个问到了这两个说法的共同点，我选的是都认为是内部structure改变了（大概就是这个意思吧，具体的记不清了）
