新SAT官方指南阅读第五篇全解析Passage1is adapted from Michael Slezak,“Space mining：the Next Gold Rush?”○C2013by New Scientist.Passage2is from the editors of New Scientist,“Taming the Final Frontier.”○C2013by New Scientist.Passage1Follow the money and you will end up in space.That’s the message from a first-of-its-kind forum on mining beyond Earth.Convened in Sydney by the Australian Centre for Space Engineering Research,the event brought together mining companies,robotics experts,lunar scientists,and government agencies 5that are all working to make space mining a reality.The forum comes hot on the heels of the2012unveiling of two private asteroid-mining firms.Planetary Resources of Washington says it will launch its first prospecting telescopes in two years, while Deep Space Industries of Virginia hopes to be harvesting metals from asteroids by2020.Another commercial venture that sprung up in2012,Golden Spike of Colorado,will be offering 10trips to the moon,including to potential lunar miners.Within a few decades,these firms may be meeting earthly demands for precious metals, such as platinum and gold,and the rare earth elements vital for personal electronics,such as yttrium and lanthanum.But like the Gold rush pioneers who transformed the Western United States,the first space miners won’t just enrich themselves.They also hope to build an off-planet 15economy free of any bonds with Earth,in which the materials extracted and processed from themoon and asteroids are delivered for space-based projects.In this scenario,water mined fro other worlds could become the most desired commodity.“In the desert,what’s worth more:a kilogram of gold or a kilogram of water?”asks Kris Zacny of HoneyBee Robotics in New York.“Gold is useless.Water will let you live.”20Water ice from the moon‘s poles could be sent to astronauts on the International Space Station for drinking or as a radiation shield.Splitting water into oxygen and hydrogen makes spacecraft fuel,so ice-rich asteroids could become interplanetary refueling stations.Companies are eyeing the iron,silicon,and aluminium in lunar soil and asteroids,which could be used in3D printers to make spare parts or machinery.Others want to turn space dirt 25into concrete for landing pads,shelters,and roads.Passage2The motivation for deep-space travel is shifting from discovery to economics.The past year has seen a flurry of proposals aimed at bringing celestial riches down to Earth.No doubt this will make a few billionaires even wealthier,but we all stand to gain:the mineral bounty and spin-off technologies could enrich us all.30But before the miners start firing up their rockets,we should pause for thought.At first glance,space mining seems to sidestep most environmental concerns:there is(probably!)no life on asteroids,and thus no habitats to trash.But its consequences-both here on Earth and in Space-merit careful consideration.Part of this is about principles.Some will argue that space’s“magnificent desolation”is not 35ours to despoil,just as they argue that our own planet’s poles should remain pristine.Others will suggest that glutting ourselves on space’s riches is not an acceptable alternative to developingmore sustainable ways of earthly life.History suggests that those will be hard lines to hold,and it may be difficult to persuade the public that such barren environments are worth preserving.After all,they exist in vast 40abundance,and even fewer people will experience them than have walked through Antarctica’s icy landscapes.There’s also the emerging off-world economy to consider.The resources that are valuable in orbit and beyond may be very different to those we prize on Earth.Questions of their relationship have barely been broached-and the relevant legal and regulatory framework is 45fragmentary,to put it mildly.Space miners,like their earthly conterparts,are often reluctant to engage with such questions.One speaker at last week’s space-mining forum in Sydney,Australia,concluded with a plea that regulation should be avoided1.But miners have much to gain from a broad agreement on the for-profit exploitation of space.Without consensus,claims will be disputed,investments 50risky,and the gains made insecure.It is all of our long-term interest to seek one out.42.In lines6-10,the author of Passage1mentions several companies primarily to(A)note the technological advances that make space mining possible.(B)provide evidence of the growing interest in space mining.(C)emphasize the large profits to be made from space mining.(D)highlight the diverse ways to carry out space mining operations.正确答案：B分析：文章1的作者列举了很多公司，例如“Planetary Resources of Washington”“Deep Space Industries of Virginia”和“Golden Spike of Colorado”，主要目的是支持他的观点：很多对太空开发感兴趣的公司，正在将太空开发变成现实。

【狒狒出品】SAT官方指南OG 第五套题解析（整理版）

Book Test #5:Section 1Sample Essay - Score of 6Most parents and teachers tell students the extremely tired cliché of the consequences of following the crowd. It is said that, in order to be a competely individual thinker, one must ignore what others say. Such advice is certainly true to some extent; unreasonable malice must be forgotten in order to keep some level ofself-esteem. However, as with most ideas, this one can not be taken in absolute form. In at least some respects, we need other people in order to understand ourselves.An excellent example of a literary character who could have psychologically benefitted from social interaction is J. Alfred Prufrock from T.S. Eliot’s poem “The Love Song of J. Alfred Prufrock.” In the poem, Prufrck desires a relationship with a woman very much, but he refrains from initiating conversation because he fears that he could not hold the interest of a sophisticated lady. Should Prufrock have taken the step to accept other people into his life, he most likely would have discovered, as the reader of the poem certainly did, that he is most articulate. Others would have impressed upon him the beauty of his words and his talent for prose. If Prufrock would have spoken his song a loud, the ladies surely would have shown him what he himself did not understand. Since the ladies would reveal Prufrock’s talents to him, it is true that we need others in order to understand ourselves.The lesson of learning from other’s opinions of yourself extends much farther than the song of a fictional character. Two days ago, in an art class, my group of students had assigned self portraits due. Most of us brought in photographs of ourselves. Nevertheless, one boy brought nothing and handed us all slips of paper. He told us to write a word to describe him, and when we had done so, he pasted the words on a poster. This must have been a revealing exercise for him because, upon the sight of such descriptions as “bitter” and “sarcastic”, he was shocked. In the case of this boy, he had not realized how his personality appeared to others. Though he might not have thought himself “bitter”, his friend’s comments certainly made him seem that way. The fact that we need others in order to understand ourselves is clearly shown by this boy’s revelation.Section 21ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. "Guarantee" in this context means to provide strong assurances that something will be the case, and "lobby for" means to influence legislators to support certain measures. If one were to insert these terms into the text, the sentence would read "Like many other groups of people in the United States who have needed laws to guarantee equal rights, Americans with disabilities have had to lobby for legislation addressing their concerns." Laws that guarantee equal rights for particular groups of people are usually passed after individuals from those groups have presented their cases to governmental officials who have the power to pass laws.Explanation for Incorrect Answer B :Choice (B) is incorrect. "Preclude" means to prevent something or make it impossible, and "enact" means to pass a law. If one were to insert these terms into the text, the sentence would read "Like many other groups of people in the United States who have needed laws to preclude equal rights, Americans with disabilities have had to enact legislation addressing their concerns." People do not need or want laws that make equal rights impossible unless these people seek to restrict the rights of others. In any case, legislators are the ones in a position to "enact" laws. People with disabilities who also have the power to enact laws would be referred to as legislators when performing their governmental function.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Ascertain" means to find out, and "consolidate" means to unite. If one were to insert these terms into the text, the sentence would read "Like many other groups of people in the United States whohave needed laws to ascertain equal rights, Americans with disabilities have had to consolidate legislation addressing their concerns." Abstract concepts like civil rights are not something that people "ascertain." In addition, it is unclear how people would benefit from consolidating different pieces of legislation.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Compound" in this context means to increase the extent of, and "contend with" means to deal with something difficult or undesirable. If one were to insert these terms into the text, the sentence would read "Like many other groups of people in the United States who have needed laws to compound equal rights, Americans with disabilities have had to contend with legislation addressing their concerns." Though "compound" can be used to mean to increase the extent of something, that use of "compound" is normally found in set phrases like "compound an error," where the object of the verb is something undesirable. Also, people desiring a particular piece of legislation do not need to "contend with" legislation that addresses their concerns; they would need, rather, to "contend with" legislation that rejects their concerns.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Suppress" in this context means to curtail or limit, and "ratify" means to validate officially. If one were to insert these terms into the text, the sentence would read "Like many other groups of people in the United States who have needed laws to suppress equal rights, Americans with disabilities have had to ratify legislation addressing their concerns." It is hard to imagine why people would seek to limit their own civil rights. Moreover, only legislators have the power to ratify laws; other people can get that power only when they are elected or appointed as legislators.2ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. "Motley" means having many different varieties. If one were to insert this term into the text, the sentence would read "The café attracts a motley clientele: a startlingly heterogeneous group of people collects there." The colon at the end of the main clause implies that the information that follows it will be a list or an explanation. In this case, the second clause provides a clear explanation of why the clientele was described as motley—that people attracted to it are heterogeneous, or quite unlike one another. Explanation for Incorrect Answer B :Choice (B) is incorrect. "Callous" means hardened. If one were to insert this term into the text, the sentence would read "The café attracts a callous clientele: a startlingly heterogeneous group of people collects there." A sentence containing a colon typically provides a list or an explanation after the colon. This sentence, however, provides a comment following the colon that in no way explains how or why the clientele should be considered hardened.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Languid" means lacking energy. If one were to insert this term into the text, the sentence would read "The café attracts a languid clientele: a startlingly heterogeneous group of people collects there." The second clause of the sentence does not explain why the writer considers the clientele to be languid; this is inconsistent with the use of a colon.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Mysterious" means difficult to explain. If one were to insert this term into the text, the sentence would read "The café attracts a mysterious clientele: a startlingly heterogeneous group of people collects there." The second clause of the sentence does not explain why the clientele is mysterious, which is inconsistent with the use of a colon. Saying that a group of people is quite varied does not explain why it was described as mysterious.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Humane" means kind or compassionate. If one were to insert this term into the text, the sentence would read "The café attracts a humane clientele: a startlingly heterogeneous group of people collects there." Saying that the group of people consists of many different kinds does not explain why the clientele was earlier described as humane. The colon ending the first clause, however, implies that an explanation of the statement in the first clause will appear in the second clause.3ANSWERS AND EXPLANATIONSExplanation for Correct Answer C :Choice (C) is correct. "Copious" means abundant, and "amassed" means accumulated. If one were to insert these terms into the text, the sentence would read "The second edition of the textbook provides copious footnotes; since the first edition, the editors have apparently amassed a great deal of background data." The structure of the sentence indicates that the second clause will help explain the first clause. It makes sense to say, then, that it is because the editors have collected a great deal of extra information that the new edition of the book has so many footnotes (typically used to provide background).Explanation for Incorrect Answer A :Choice (A) is incorrect. "Meager" means small in quantity, and "accumulated" means brought together. If one were to insert these terms into the text, the sentence would read "The second edition of the textbook provides meager footnotes; since the first edition, the editors have apparently accumulated a great deal of background data." The second clause of the sentence is presented as an explanation of the first clause. However, the reader would expect the second clause to say why the editors included such a small number of footnotes; the second clause, in fact, does the opposite.Explanation for Incorrect Answer B :Choice (B) is incorrect. "Illegible" means unreadable, and "clarified" means made clear or understandable. If one were to insert these terms into the text, the sentence would read "The second edition of the textbook provides illegible footnotes; since the first edition, the editors have apparently clarified a great deal of background data." With those two terms inserted, the two clauses of the sentence do not make much sense together. Editors would not deliberately put unreadable footnotes in a book. The second clause does not respond to this puzzling situation.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Voluminous" in this context means great in number, and "excised" means cut out. If one were to insert these terms into the text, the sentence would read "The second edition of the textbook provides voluminous footnotes; since the first edition, the editors have apparently excised a great deal of background data." The structure of the sentence makes the reader expect that the second clause will help to explain something about the large number of footnotes. The second clause, however, unhelpfully talks about the removal of information, without saying how this is supposed to be compatible with the insertion of the many footnotes.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Monotonous" in this context means repetitiously dull, and "embellished" means enhanced. If one were to insert these terms into the text, the sentence would read "The second edition of the textbook provides monotonous footnotes; since the first edition, the editors have apparently embellished a great deal of background data." It does not make sense to say that the editors have enhanced data to make for dull footnotes in the new edition of a book.4ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. "Dubious" means in doubt, and "self-serving" means tending to address one's own needs or desires. If one were to insert these terms into the text, the sentence would read "Professor Fernandez has been dubious about most of the purportedly humanitarian aspects of the colonial government and has insisted that its actions were, on the contrary, self-serving." The first missing term describes the professor's attitude toward the government's supposed humanitarianism. The phrase "on the contrary" prepares the reader to believe that the second missing term will be incompatible with "humanitarian aspects." A scholar would indeed doubt that the programs of a government were humanitarian or charitable if they turned out to serve the selfish needs of the government itself.Explanation for Incorrect Answer B :Choice (B) is incorrect. "Enthusiastic" means having great appreciation, and "contemptible" means worthy of strong dislike. If one were to insert these terms into the text, the sentence would read "Professor Fernandez has been enthusiastic about most of the purportedly humanitarian aspects of the colonial government and has insisted that its actions were, on the contrary, contemptible." A person who finds a government's actions despicable would not be enthusiastic about that government.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Disparaging" means belittling, and "sporadic" means occurring at irregular intervals. If one were to insert these terms into the text, the sentence would read "Professor Fernandez has been disparaging about most of the purportedly humanitarian aspects of the colonial government and has insisted that its actions were, on the contrary, sporadic." Saying that certain actions occur at irregular intervals does not serve as reasonable grounds for the charge that a government is not genuinely interested in promoting humanitarian goals. Specifically, the phrase "on the contrary" leads the reader to expect that "humanitarian" goals would be incompatible with "sporadic" actions. Such a contrast, however, does not exist. Explanation for Incorrect Answer D :Choice (D) is incorrect. "Excited" means emotionally aroused, and "gratuitous" in this context means unnecessary. If one were to insert these terms into the text, the sentence would read "Professor Fernandez has been excited about most of the purportedly humanitarian aspects of the colonial government and has insisted that its actions were, on the contrary, gratuitous." Someone so excited about a government would be unlikely to claim that its humanitarian actions were unnecessary.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Disillusioned" means very disappointed, and "benevolent" means well-intentioned. If one were to insert these terms into the text, the sentence would read "Professor Fernandez has been disillusioned about most of the purportedly humanitarian aspects of the colonial government and has insisted that its actions were, on the contrary, benevolent." One would expect the humanitarian actions of a government to be benevolent, or well-intentioned. Therefore, the expectations set up by the words "on the contrary" are not fulfilled. A person disillusioned by a government would not explain that position by pointing out that the government's humanitarian actions were well-intentioned.5ANSWERS AND EXPLANATIONSExplanation for Correct Answer E :Choice (E) is correct. "An amalgamation" means a mixture. If one were to insert this term into the text, the sentence would read "Concrete is an amalgamation of many materials, a composite of rocks, pebbles, sand, and cement." A comma placed in a position like the one after "materials" normally introduces a phrase thathelps to define or explain the noun phrase preceding the comma. In this case, the phrase explains that the amalgamation is a composite, or mixture, of distinct materials.Explanation for Incorrect Answer A :Choice (A) is incorrect. "A conflagration" means a large fire. If one were to insert this term into the text, the sentence would read "Concrete is a conflagration of many materials, a composite of rocks, pebbles, sand, and cement." It does not make sense to say that concrete is a fire.Explanation for Incorrect Answer B :Choice (B) is incorrect. "A distillation" means a purification by boiling and revaporization. If one were to insert this term into the text, the sentence would read "Concrete is a distillation of many materials, a composite of rocks, pebbles, sand, and cement." The product of a distillation would probably be a liquid, not a solid.Explanation for Incorrect Answer C :Choice (C) is incorrect. "A concordance" means an alphabetical index of words in a text. If one were to insert this term into the text, the sentence would read "Concrete is a concordance of many materials, a composite of rocks, pebbles, sand, and cement." Concrete and the processes used to make it have nothing to do with book indexes.Explanation for Incorrect Answer D :Choice (D) is incorrect. "An aberration" means a deviation from the expected course. If one were to insert this term into the text, the sentence would read "Concrete is an aberration of many materials, a composite of rocks, pebbles, sand, and cement." Neither concrete nor the processes of making it can be called deviations from any course of action.6ANSWERS AND EXPLANATIONSExplanation for Correct Answer E :Choice (E) is correct. Moraga is cited as an example of a writer who found it difficult to decide whether to write in English or in Spanish. The title of her book is half in English and half in Spanish, and her comment "I lack language" (line 3) reinforces her sense that there is no satisfactory resolution of her dilemma.Explanation for Incorrect Answer A :Choice (A) is incorrect. The passage says that Hispanic American writers face problems in choosing a language to write in, but it says nothing about problems associated with getting works published after they have been written.Explanation for Incorrect Answer B :Choice (B) is incorrect. Moraga is cited as a writer experiencing a problem frequently faced by Hispanic American writers. The passage is primarily concerned with this general problem, not with this particular writer and her achievements.Explanation for Incorrect Answer C :Choice (C) is incorrect. According to the passage, the title of Moraga's book expresses the difficulty she perceives "in writing in one language when one has lived in another" (line 7-8). There is no suggestion by the author of the passage as to whether Moraga is regarded as being especially expressive as a writer. Explanation for Incorrect Answer D :Choice (D) is incorrect. The passage does not say anything about new artistic approaches, nor does it suggest that Moraga's approach is a novel one. Rather, the point is that the difficulties Moraga has experienced in choosing a language are common to Hispanic American writers.7ANSWERS AND EXPLANATIONSExplanation for Correct Answer D :Choice (D) is correct. The problem presented in the passage is that of "narrating personal experiences in one language when one has lived in another" (lines 7-8). Someone described as a Russian novelist living in the United States is likely to have lived much of his or her life in Russia, speaking Russian, and whatever insights such a person has are likely to be based, at least in part, on experiences in Russia. So the problem of a Russian novelist living in the United States who has difficulty expressing insights in American English is similar to the problem presented in the passage.Explanation for Incorrect Answer A :Choice (A) is incorrect. While a Hispanic American living in a South American country might, like Moraga, feel some conflict between the use of Spanish and English, painters do not primarily employ the medium of language in their work, so this is not a close analogy. Further, there is no mention of bilingual writers' ability to sell their work.Explanation for Incorrect Answer B :Choice (B) is incorrect. The problem experienced by the Cherokee columnist is how much background information needs to be supplied to make writings dealing with Native American cultures understandable to readers of national newspapers. This is a different problem from the one presented in the passage, which has to do with using a different language to write about experiences than the one used while living those experiences. A Cherokee columnist might also have this problem, but not as a result of making the assumption that most readers are unfamiliar with Native American cultures.Explanation for Incorrect Answer C :Choice (C) is incorrect. The problem in the passage is that of using one language in daily life and then trying to write about one's experiences in a different language. An African American novelist is unlikely to be writing in a completely different language than the one spoken throughout life. Moreover, the historical past of African Americans is not something that a living African American novelist can have experienced.Explanation for Incorrect Answer E :Choice (E) is incorrect. Trying to write essays for two audiences with very different linguistic and cultural backgrounds poses a different sort of problem from that described in the passage.8ANSWERS AND EXPLANATIONSExplanation for Correct Answer B :Choice (B) is correct. The author characterizes the movie in which HAL appears as a "masterpiece" (line 1) and describes the portrait of HAL as "finely honed" (line 3), or precise, which clearly expresses appreciation. Explanation for Incorrect Answer A :Choice (A) is incorrect. The attitude toward the portrait of HAL and toward HAL's creators is one of admiration, not resentment, or ill will.Explanation for Incorrect Answer C :Choice (C) is incorrect. There is no indication of any confusion or ambivalence on the part of the author toward the portrait of HAL that Clarke and Kubrick created. It is one of admiration and appreciation throughout.Explanation for Incorrect Answer D :Choice (D) is incorrect. The author admires the portrait of HAL, but goes on to say that computers are in some ways even better now. So the author's attitude is not one of veneration or wonder, or awe.Explanation for Incorrect Answer E :Choice (E) is incorrect. There is no indication that the author is being sarcastic in admiring the depiction if HAL. Since the author is not ridiculing the portrait, the author's attitude toward the portrait of HAL is not derisive.9ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. In the last sentence, the author points out that besides being "vastly smaller and more portable than HAL" (line 10), today's computers use software interfaces that do not require the type of manual controls required for HAL; in this context, site mobility, and new software interfaces are clearly advantages.Explanation for Incorrect Answer B :Choice (B) is incorrect. The last sentence makes it clear that the availability of software interfaces that make manual controls unnecessary is an aspect of the future that Clarke and Kubrick failed to envision. Explanation for Incorrect Answer C :Choice (C) is incorrect. The "software interfaces" (line 11) referred to make it possible to use today's computers without the types of manual controls required to operate HAL. Such software interfaces were not envisioned by HAL's creators. Manual controls are presented as the only way—not one of many ways— that human beings could access computers like HAL.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Software" is referred to in the passage only in connection with the kind of software interfaces that make certain types of manual controls unnecessary. There is no mention of attempts to override software.Explanation for Incorrect Answer E :Choice (E) is incorrect. By referring to "software interfaces" (lines 11) and the manual controls that such software makes unnecessary, the author suggests that current computers are superior to HAL in certain respects. But nothing is either said or implied about whether current computers are inferior to HAL in their ability to simulate human intelligence and emotions10ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. In the beginning of the sentence in which the quotation from the Constitution occurs, women are contrasted with "indentured servants, slaves, and American Indians" (line 6). Women who did not belong to one of these other groups were classified by the Constitution as among "the whole number of freepersons" (line 10). But for these other groups, who were not "free persons," the question of voting and being elected to public office was seen as an issue, whereas for women the issue did not even arise. The quotation from the Constitution emphasizes the internal inconsistency—of classifying women as equivalent to men in one respect and as being unequal to men in another respect.Explanation for Incorrect Answer B :Choice (B) is incorrect. The quotation from the Constitution serves to emphasize that women were "free persons" in a very limited sense, not to demonstrate that women were free, while servants, slaves, and American Indians were not.Explanation for Incorrect Answer C :Choice (C) is incorrect. The passage specifically says that women could not vote or "be elected to public office" (line 11-12). There is no suggestion that women could get around this restriction by being appointed rather than elected.Explanation for Incorrect Answer D :Choice (D) is incorrect. According to the passage, equitable representation, required a reasonably accurate count of "the whole number of free persons" (line 10) in a state. The passage does suggest that there were many people who did not get counted because they were not classified as "free persons," but this is not the same as illustrating the difficulty "of achieving equitable representation."Explanation for Incorrect Answer E :Choice (E) is incorrect. The passage does not use the term "free citizen." The quotation is used in the course of making the point that women were regarded as "free persons" (line 10). Nothing in the passage suggests that someone could be a free person but not a free citizen.11ANSWERS AND EXPLANATIONSExplanation for Correct Answer E :Choice (E) is correct. The passage says that "women in large numbers had been involved in political actions in the American Revolution" (lines 14-15), and goes on to mention “fund-raising, tea boycotts, and actions against profiteering merchants” as examples of ways women had found for "exerting influence on political events" (lines 17-18).Explanation for Incorrect Answer A :Choice (A) is incorrect. The passage mentions “fund-raising, tea boycotts, and actions against profiteering merchants” as ways women had found for "exerting influence on political events" (lines 17-18). But exerting influence on events connected with the American Revolution is not the same as altering the course of the American Revolution.Explanation for Incorrect Answer B :Choice (B) is incorrect. The activities mentioned in lines 18-19 are cited as examples of political activities undertaken by women in support of the American Revolution. There is no suggestion that the women involved saw these activities as protests against specifically male dominance as opposed to protests against British dominance in general. It is only later that the passage discusses ways women began to raise the issue of rights for women.Explanation for Incorrect Answer C :。

2022剑桥英语5级阅读理解专项训练题及详解阅读理解(A)Three travelers, Allan, Carl and Paul were sitting on the chairsin a train station. They were waiting for a train that was very late. To pass the time, they began talking to each other.At first, they talked about the weather and their work. Then Paul said, "Tell me—what would you most like to do if your doctor tellyou that you have only three months to live?"The other two men thought about this for a while, then Carl spoke.“Well,” he said, “if I have only three months to live, I’ll take all my money out of the bank and go to foreign countries for holidays with my best friend, Erik. I’d like to travel to the places i n the world as many as possible. And I’ll stay at the best hotels and then eat the best food. I think I’ll have a wonderful time.”“That’s very interesting,” Paul said.With these words, he turned to the other man, saying, “And what about you?”“I’ll tell you a secret,” Allan said. “I always want to be a racing driver. So if I have only three months to live, the firstthing I’d like to do is to sell my house. With the money I’ll buy the fastest car in the world. Maybe I can enter all the big motor races.”Then he laughed, “I might even end up (以……而告终) world champion.”“Now it’s your turn,” Allan went on, “If your doctor tell you the bad news, what would you most like to do?”“Oh,” said Paul with a smile. “I’ll go and see another doctor.”1.

I hoped it would be quick — and so it was.“Isoon knew that David Prig was no learner. After ten minuteshis sister came outside and began to play tennis against a wall. The boy seemed to lose interest in our game. He moved a piece (棋子) without care. I gave my attention to the board.“Call me when you are ready, Mr. Watson,” he said.When I was ready? I looked up.

先出现的四题是人名观点配对题。

接下来的六题是概括归纳题。

最后则是必考题型是非无判断题。

这三类题目全都是细节信息，主要考察学生的信息搜索能力和语言转换的能力。

同时，在短时间内完成所有的题目的能力也对考生提出了较高的要求。

第一种人名观点配对题和大多数考试的出题方式有些许的不同。

以往的考试真题中的出题方式都是以人名作为选项，而把观点作为题目的。

这样一来，就导致了人名作为选项极有可能产生多选的状况。

这样一来就增加了做题的时间和难度。

而在强化玻璃这篇阅读题目中，人名则作为了题目，而观点则放到了选项当中，因此，一个观点配多个人名的可能性就极小了。

但是这样一来会导致另外一个难点：题目和选项都不按照顺序原则出现。

从而对于考生的信息搜索能力的要求就大幅增加了。

作为雅思阅读的讲师来说，对于这篇文章的教学中要充分讲解该考题的难度和学生的做题方法。

在阅读文章中，会出现超过题目中的人名的数量，也会产生相当多的干扰项。

如何排除干扰以及指导学生科学的阅读方法是每个教师在讲解这篇文章的考试技巧时的重要一环!接下来的 Summary 题目则是该文章的题目中较难的题型!也是雅思阅读讲师必讲的题目!首先值得关注的这道摘要归纳题是有选项的 Summary 。

而选项是 A - P ，数量非常多。

在题目的 instruction 中 Complete the summary with list of words A - P below 我们可以发现考生在填写答案是应把字母和单词写完整，否则有可能造成不必要的失分。

这里要特别指出，这篇文章的归纳题并非按照顺序原则来出题，而且包含了大量的词汇同义转换和句子同义转换。

SAT新版OG阅读讲解

SAT新版OG阅读讲解SAT新版OG阅读讲解下文是yjbys店铺精心整理的SAT新版OG阅读讲解，此文章适合所有准备阅读考试的考生，仅非适用于SAT er，希望能够帮助到大家，在准备阅读考试的过程中达到事半功倍的效果。

在讲题思路之前，我先讲一下我解题所基于的理论，这样会更有助于大家看懂和理解后面每一道题解题的过程。

Critical Reading分为Sentence completion(句子填空)和Passage Based Reading(篇章阅读)两个部分。

在我看来，其实后者篇章阅读做题其实也可以看作是句子填空题，无非就是把题干中所缺的内容填完整即可(譬如OG391-6， In line 12, the author implies that being “human” includes________)。

只不过句子填空是从句子本身获得所填的信息，填上一两个学术词汇，而阅读题是从文中获得空所缺的信息(注意：有些Question，也可以仅从题干中就能获取解题的'全部信息，无需文中提炼，以后讲题中会提到)。

简而言之，从形式上来讲，可以称“阅读做题”为“补充句子”。

既然为补充句子，所补充的内容一定得是题所缺的内容，反之，如果填上的不是题所缺的内容，必为错误选项。

那如何知道题所缺的内容(譬如情感，主旨，结构，词意，修辞等等)，便成为了解题的第一步，然后随之而来的第二步就是去Locate(定位)一道题所需的内容，而此步也成为了解题中最为关键，最为复杂的一步，但往往此步骤也是被学生最容易忽视的一步。

因为SAT的大部分阅读题的题干中都有line，指定了行号(譬如OG391-6，In line 12, the author implies that being “human” includes________)，所以学生变不假思索的去看行号中指定的内容。

但是，我们去看行号指定内容，是默认题所缺的信息来自于行号才行，但如果题所缺内容根本不在行号指定文字里面，那即使行号指定内容理解得再透彻，选项对应得再好，想必这也不一定是正确选项吧。

5月新SAT真题(阅读+答案)

考情汇总1、难点还是集中在阅读上，小说和双篇文章登顶此次最难的两篇。

2、此次考试的语法部分没有特别难的问题，考生均反映难度适中。

3、写作部分选取的文章非常有利于考生展开分析！4、此次考试数学非常容易，就连北美的同学（美国人）都反映此次数学几乎无压力！5、加试部分为数学，难度依旧非常低。

阅读部分第一篇：小说小说选自美国经典现实主义小说 Sister Carrie，XXX为 Theodore Dreiser，最早出版于1900年。

小说描述了一个贫困的乡村姑娘来到大城市生活，内心向往富足的生活。

为了摆脱穷困，先后跟推销员和酒店经理同居，最后历经磨难，终成一个著名演员。

小说截取的部分在论述 Carrie 在看一出关于纽约奢华生活的舞台剧。

台上演员华衣美服，居所装修华丽，生活应有尽有。

Carrie 不免生出羡慕向往之心。

舞台剧还体现了这些生活在理想状态人还收到感情爱情嫉妒的折磨，这更让Carrie 羡慕，谁不愿意坐在金椅子里发愁，谁会不愿意在洒了香水的挂毯、有坐垫的家具和穿着制服的仆人那样的条件下受些折磨呢？回到她小小的 flat（套间），Carrie 暗暗下决心，假如我不能过上那样的生活，我就等于没有活过，或者说自己活过。

第二篇、自然科学科研型文章研究的主要目的在于探究人类大脑如何区分现实和虚拟（广告/小说人物/童话)信息。

研究者呈现给受试者不同的场景：一，广播听到或报纸阅读到关于布什(总统)和灰姑娘，二，跟总统或跟灰姑娘共进晚餐。

然后利用 MRL 研究他们大脑不同区域的活跃度。

现实和虚拟信息都会激起大脑某些区域比如管记忆的海马沟。

不同的是，现实信息还会激起独特的一个脑区域，这个脑区域跟短时记忆和注意力有关。

一直相对，虚拟的信息会激起一个跟语言相关的脑区域。

研究者后来又在另一拨受试者重复了实验，这次根据跟受试者现实相关的程度设置信息。

结果还是成立，研究者进一步拓展，现实和虚拟其实跟不在于人物本身的现实程度，更跟信息与受试者现实生活的相关度有关。

托福TPO5阅读真题文本Part1Minerals and PlantsResearch has shown that certain minerals are required by plants for normal growth and development. The soil is the source of these minerals, which are absorbed by the plant with the water from the soil. Even nitrogen, which is a gas in its elemental state, is normally absorbed from the soil as nitrate ions. Some soils are notoriously deficient in micro nutrients and are therefore unable to support most plant life. So-called serpentine soils, for example, are deficient in calcium, and only plants able to tolerate low levels of this mineral can survive. In modern agriculture, mineral depletion of soils is a major concern, since harvesting crops interrupts the recycling of nutrients back to the soil.Mineral deficiencies can often be detected by specific symptoms such as chlorosis (loss of chlorophyll resulting in yellow or white leaf tissue), necrosis (isolated dead patches), anthocyanin formation (development of deep red pigmentation of leaves or stem), stunted growth, and development of woody tissue in an herbaceous plant. Soils are most commonly deficient in nitrogen and phosphorus. Nitrogen-deficient plants exhibit many of the symptoms just described. Leaves develop chlorosis; stems are short and slender, and anthocyanin discoloration occurs on stems, petioles, and lower leaf surfaces. Phosphorus-deficient plants are often stunted, with leaves turning a characteristic dark green, often with the accumulation ofanthocyanin. Typically, older leaves are affected first as the phosphorus is mobilized to young growing tissue. Iron deficiency is characterized by chlorosis between veins in young leaves.Much of the research on nutrient deficiencies is based on growing plants hydroponically, that is, in soilless liquid nutrient solutions. This technique allows researchers to create solutions that selectively omit certain nutrients and then observe the resulting effects on the plants. Hydroponics has applications beyond basic research, since it facilitates the growing of greenhouse vegetables during winter. Aeroponics, a technique in which plants are suspended and the roots misted with a nutrient solution, is another method for growing plants without soil.While mineral deficiencies can limit the growth of plants, an overabundance of certain minerals can be toxic and can also limit growth. Saline soils, which have high concentrations of sodium chloride and other salts, limit plant growth, and research continues to focus on developing salt-tolerant varieties of agricultural crops. Research has focused on the toxic effects of heavy metals such as lead, cadmium, mercury, and aluminum; however, even copper and zinc, which are essential elements, can become toxic in high concentrations. Although most plants cannot survive in these soils, certain plants have the ability to tolerate high levels of these minerals.Scientists have known for some time that certain plants, called hyperaccumulators, can concentrate minerals at levels a hundredfold or greater than normal. A survey of known hyperaccumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice. Hyperaccumulators run the entire range of the plant world. They may be herbs, shrubs, or trees. Manymembers of the mustard family, spurge family, legume family, and grass family are top hyperaccumulators. Many are found in tropical and subtropical areas of the world, where accumulation of high concentrations of metals may afford some protection against plant-eating insects and microbial pathogens.Only recently have investigators considered using these plants to clean up soil and waste sites that have been contaminated by toxic levels of heavy metals-an environmentally friendly approach known as phytoremediation. This scenario begins with the planting of hyperaccumulating species in the target area, such as an abandoned mine or an irrigation pond contaminated by runoff. Toxic minerals would first be absorbed by roots but later relocated to the stem and leaves. A harvest of the shoots would remove the toxic compounds off site to be burned or composted to recover the metal for industrial uses. After several years of cultivation and harvest, the site would be restored at a cost much lower than the price of excavation and reburial, the standard practice for remediation of contaminated soils. For examples, in field trials, the plant alpine pennycress removed zinc and cadmium from soils near a zinc smelter, and Indian mustard, native to Pakistan and India, has been effective in reducing levels of selenium salts by 50 percent in contaminated soils.Paragraph 1: Research has shown that certain minerals are required by plants for normal growth and development. The soil is the source of these minerals, which are absorbed by the plant with the water from the soil. Even nitrogen, which is a gas in its elemental state, is normally absorbed from the soil as nitrate ions. Some soils are notoriously deficient in micro nutrients and are therefore unable to support most plant life. So-called serpentinesoils, for example, are deficient in calcium, and only plants able to tolerate low levels of this mineral can survive. In modern agriculture, mineral depletion of soils is a major concern, since harvesting crops interrupts the recycling of nutrients back to the soil.托福TPO5阅读真题题目Part11. According to paragraph 1, what is true of plants that can grow in serpentine soil?○ They absorb micronutrients unusually well.○ They require far less calcium than most plants do.○ They are able to absorb nitrogen in its elemental state.○ They are typically crops raised for food.Paragraph 2: Mineral deficiencies can often be detected by specific symptoms such as chlorosis (loss of chlorophyll resulting in yellow or white leaf tissue), necrosis (isolated dead patches), anthocyanin formation (development of deep red pigmentation of leaves or stem), stunted growth, and development of woody tissue in an herbaceous plant. Soils are most commonly deficient in nitrogen and phosphorus. Nitrogen-deficient plants exhibit many of the symptoms just described. Leaves develop chlorosis; stems are short and slender, and anthocyanin discoloration occurs on stems, petioles, and lower leaf surfaces. Phosphorus-deficient plants are often stunted, with leaves turning a characteristic dark green, often with the accumulation of anthocyanin. Typically, older leaves are affected first as the phosphorus is mobilized to young growing tissue. Iron deficiency is characterized by chlorosis between veins in young leaves.2. The word "exhibit" in the passage is closest in meaning to○ fight off○ show○ cause○ spread3. According to paragraph 2, which of the following symptoms occurs in phosphorus-deficient plants but not in plants deficient in nitrogen or iron?○ Chlorosis on leaves○ Change in leaf pigmentation to a dark shade of green○ Short, stunted appearance of stems○ Reddish pigmentation on the leaves or stem4. According to paragraph 2, a symptom of iron deficiency is the presence in young leaves of○ deep red discoloration between the veins○ white or yellow tissue between the veins○ dead spots between the veins○ characteristic dark green veinsParagraph 3: Much of the research on nutrient deficiencies is based on growing plants hydroponically, that is, in soilless liquid nutrient solutions. This technique allows researchers to create solutions that selectively omit certain nutrients and then observe the resulting effects on the plants. Hydroponics has applications beyond basic research, since it facilitatesthe growing of greenhouse vegetables during winter. Aeroponics, a technique in which plants aresuspended and the roots misted with a nutrient solution, is another method for growing plants without soil.5. The word "facilitates" in the passage is closest in meaning to○ slows down○ affects○ makes easier○ focuses on6. According to paragraph 3, what is the advantage of hydroponics for research on nutrient deficiencies in plants?○ It allows researchers to control what nutrients a plant receives.○ It allows researchers to observe the growth of a large number of plants simultaneously.○ It is possible to directl y observe the roots of plants.○ It is unnecessary to keep misting plants with nutrient solutions.7. The word "suspended" in the passage is closest in meaning to○ grown○ protected○ spread out○ hungParagraph 5: Scientists have known for some time that certain plants, called hyperaccumulators, can concentrate minerals at levels a hundredfold or greater than normal. A survey of known hyperaccumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice. Hyperaccumulators run the entire range of the plant world. They may be herbs, shrubs, or trees. Many members of the mustard family, spurge family, legume family, and grass family are top hyperaccumulators. Many are found in tropical and subtropical areas of the world, where accumulation of high concentrations of metals may afford some protection against plant-eating insects and microbial pathogens.8. Why does the author mention "herbs", "shrubs", and "trees"?○ To provide examples of plant types that cannot tolerate high levels of harmful minerals.○ To show why so many plants are hyperaccumulators.○ To help explain why hyperaccumulators can be found in so many different places.○ To emphasiz e that hyperaccumulators occur in a wide range of plant types.9. The word "afford" in the passage is closest in meaning to○ offer○ prevent○ increase○ removeParagraph 6: Only recently have investigators considered using these plants to clean up soil and waste sites that have been contaminated by toxic levels of heavy metals-an environmentally friendly approach known as phytoremediation. This scenario begins with the planting of hyperaccumulating species in the target area, such as an abandoned mine or an irrigation pond contaminated by runoff.

For examples, in field trials, the plant alpine pennycress removed zinc and cadmium from soils near a zinc smelter, and Indian mustard, native to Pakistan and India, has been effective in reducing levels of selenium salts by 50 percent in contaminated soils.10. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.○ Before considering phytoremediation, hyperaccumulating species of plants local to the target area must be identified.○ The investigation begins with an evaluation of toxic sites in the target area to determine the extent of contamination.○ The first step in phytoremediation is the planting of hyperaccumulating plants in the area to be cleaned up.○ Mines and irrigation ponds can be kept from becoming contaminated by planting hyperaccumulating species in targeted areas.11. It can be inferred from paragraph 6 that compared with standard practices for remediation of contaminated soils, phytoremediation○ does not allow for the use of the removed minerals for industrial purposes○ can be faster to implement○ is equally friendly to the environment○ is less suitable for soils that need to be used within a short period of time12. Why does the author mention "Indian mustard"?○ To warn about possible risks involved in phytoremediation ○ To help illustrate the potential of phytoremediation○ To show that hyperaccumulating plants grow in many regions of the world○ To explain how zinc contaminati on can be reducedParagraph 5: Scientists have known for some time that certain plants, called hyperaccumulators, can concentrateminerals at levels a hundredfold or greater than normal. ■A survey of known hyperaccumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice. ■Hyperaccumulators run the entire range of the plant world. ■They may be herbs, shrubs, or trees. ■Many members of the mustard family, spurge family, legume family, and grass family are top hyperaccumulators.

Questions 6-7 are based on the following passage.The critic Edmund Wilson was not a self-consciousletter writer or one who tried to sustain studied mannerisms. Nor did he resort to artifice or entangle himself in circumlocutions. The young, middle-aged, and old Wilson5 speaks directly through his letters, which are informal for the most part and which undisguisedly reflect his changing moods. On occasion-in response, perhaps, to the miseryof a friend or a public outrage or a personal challenge-he can become eloquent, even passionate, but that is not his10 prevailing tone.文章大意：文章主要讲评论家埃德蒙威尔逊在写信的风格上不拘一格，直言不讳，他的一生都是这样的风格不扭捏拘谨，应对各种挑战时候也能从容不会能言善辩。

长难词：mannerisms特殊习惯，矫揉造作，artifice 欺骗entangle 是纠缠，混乱circumlocution委婉的说法 eloquent雄辩的，有口才的，outrage 愤怒 undisguisedly公开的，不伪装的。
