Virtually everything astronomers known about objects outside the solar system is based on the detection of photons—quanta of electromagnetic radiation.(老观点：探测宇宙用P) Yet there is another form of radiation that permeates the universe: neutrinos.（新观点：用N） With (as its name implies) no electric charge, and negligible mass, the neutrino interacts with other particles so rarely that a neutrino can cross the entire universe, even traversing substantial aggregations of matter, without being absorbed or even deflected. Neutrinos can thus escape from regions of space where light and other kinds of electromagnetic radiation are blocked by matter. Furthermore, neutrinos carry with them information about the site and circumstances of their production: therefore, the detection of cosmic neutrinos could provide new information about a wide variety of cosmic phenomena and about the history of the universe.（N的优点：1。与其他物质接触少，所以不受干扰 2。带着环境的信息）
But how can scientists detect a particle that interacts so infrequently with other matter? Twenty-five years passed between Pauli’s hypothesis that the neutrino existed and its actual detection: since then virtually all research with neutrinos has been with neutrinos created artificially in large particle accelerators and studied under neutrino microscopes. But a neutrino telescope, capable of detecting cosmic neutrinos, is difficult to construct. No apparatus can detect neutrinos unless it is extremely massive, because great mass is synonymous with huge numbers of nucleons (neutrons and protons), and the more massive the detector, the greater the probability of one of its nucleon’s reacting with a neutrino. In addition, the apparatus must be sufficiently shielded from the interfering effects of other particles.（问题：N与其他物质接触少，难测试。详细解释：要建N的望远镜，要极大还要避免与其他物质的接触，不可能）
Fortunately, a group of astrophysicists has proposed a means of detecting cosmic neutrinos by harnessing the mass of the ocean.（解决：用海洋的物质） Named DUMAND, for Deep Underwater Muon (muon: n. μ介子) and Neutrino Detector, the project calls for placing an array of light sensors at a depth of five kilometers under the ocean surface. The detecting medium is the seawater itself: when a neutrino interacts with a particle in an atom of seawater, the result is a cascade of electrically charged particles and a flash of light that can be detected by the sensors. The five kilometers of seawater above the sensors will shield them from the interfering effects of other high-energy particles raining down through the atmosphere.（N的反应可用感应器接受，也可避免其他物质的干扰）解决的办法：用海水
The strongest motivation for the DUMAND project is that it will exploit an important source of information about the universe. （办法的优点：能够探测宇宙的信息）The extension of astronomy from visible light to radio waves to x-rays and gamma rays never failed to lead to the discovery of unusual objects such as radio galaxies, quasars, and pulsars. Each of these discoveries came as a surprise. Neutrino astronomy will doubtless bring its own share of surprises.（N必将带来新的发现）
9. According to the passage, one of the methods used to establish the properties of neutrinos was细节题，我没有回去定位，凭记忆做，选了D，
(A) detection of photons
(B) observation of the interaction of neutrinos with gamma rays
(C) observation of neutrinos that were artificially created since then virtually all research with neutrinos has been with neutrinos created artificially in large particle accelerators and studied under neutrino microscopes.
(D) measurement of neutrinos that interacted with particles of seawater（C）Fortunately, a group of astrophysicists has proposed a means of detecting cosmic neutrinos by harnessing the mass of the ocean.
(E) experiments with electromagnetic radiation
D错在哪里呢是因为这只是建议而不是事实吗
谢谢
pumpkin, 谢谢你的回答
C对我同意
D 错在面米有讲到measurement. 不能臆测的啊 同意

对吗
对选项的混淆上不知有什么好办法 我总是中招
谢谢
pumpin, 不是新老观点对比型 是问题解决型

XDF的说法可能有点教条 因为有些文章的结构可能是混合的 可能不是那么清晰
但是 读文章时有个框框 对全文的理解和记忆都有很大的帮助 pumpkin 你
说呢
Have a good day.
nodding
偶也是XDF读过的.GRE. 呵呵呵
就是觉得东方的阅读讲的不到位.
呢
支持
我没机会上新东方只是听了网上的教程
感觉文章的套路 /段落思考/题型 很有道理 如果能早认识到可以少走弯路
不过现在的阅读仍然很次
第二段,讲如何探测中微子.探测它困难,原因是由于它的属性.而对它属性的探究是从人工试验观测得来的.
第三段,探测它的一个方法.
问题9问得是证实中微子属性的方法.
而D的方法测的是中微子existence,不是properties.
这是我的分析,请指教!
还是不懂，这句话one of the methods used to establish the properties of neutrinos怎么定位？
(C) observation of neutrinos that were artificially created
ｎｎ的解释：since then virtually all research with neutrinos has been with neutrinos created artificially in large particle accelerators and studied under neutrino microscopes.
是从properties推出来的吗？那跟解释的那句话做连接？？
同意楼上题目中有「was」，
所以是问过去的方法，因此答案是C。

同意
确实是定位问题，就这么个词。。
这个establish the properties 和 its actual detection有点像，只是有点。。呵呵

说的很赞 一语惊醒梦中人!!!!!!!

Fortunately, a group of astrophysicists has proposed a means of detecting cosmic neutrinos by harnessing the mass of the ocean. Named DUMAND, for Deep Underwater Muon (muon: n. μ介子) and Neutrino Detector, the project calls for placing an array of light sensors at a depth of five kilometers under the ocean surface.

作者已经说了 是has proposed a means 但是并没有说这个means已经使用了 并没有已经用来measurement了 再看后面说when...the result is...当...的时候，结果是...而不是说已经做过这个事情了
这几天总结阅读有一点体会很深 就是作者的语气 如果作者说sth. could worsen the environment in the future那么答案中经常后悔有迷惑选项说sth. caused damage to environment这是不对的 因为作者根本没有陈述出这个事情已经发生了 只是说could
我感觉和这个题的D有点类似
第九题题干中的properties就是characteristics的意思 就是N的特点
然而当我回过头来再读文章的时候豁然明白 下面的高亮部分不就是N的特点么!!! 第一，它rarely与别的东西作用；第二，它还会带回information 那么第九题问的是这两个properties是怎么被发现的？那么第二段就告诉你是这样的:But how can scientists detect a particle that interacts so infrequently with other matter? Twenty-five years passed between Pauli’s hypothesis that the neutrino existed and its actual detection: since then virtually all research with neutrinos has been with neutrinos created artificially in large particle accelerators and studied under neutrino microscopes.
Virtually everything astronomers known about objects outside the solar system is based on the detection of photons—quanta of electromagnetic radiation. (看到这个virtually就要anticipate可能作者说的是一个普遍情况下面就要开始转折了，果然yet)Yet there is another form of radiation that permeates the universe: neutrinos. (看到这里马上anticipate作者是不是要讲它的特点了，作者为什么要提出这个neutrinos呢，肯定是它有什么特别之处，期待中，往下看，果然特别)第一With (as its name implies) no electric charge, and negligible mass, the neutrino interacts with other particles so rarely that a neutrino can cross the entire universe, even traversing substantial aggregations of matter, without being absorbed or even deflected. Neutrinos can thus escape from regions of space where light and other kinds of electromagnetic radiation are blocked by matter.
第二Furthermore, neutrinos carry with them information about the site and circumstances of their production: therefore, the detection of cosmic neutrinos could provide new information about a wide variety of cosmic phenomena and about the history of the universe.
