3月SAT亚太考试内容回顾阅读三精编版

2018年3月SAT亚太考试内容回顾阅读三第三篇：科学类鸟类协作可以抵御异种鸟类在自己鸟窝里面下蛋影响自身繁殖。

然后需要补充的细节是如果不小心异种鸟繁殖，会影响自己的繁殖。

所以一开始就要把成人的鸟赶出去，这个过程中socially 很重要。

原文：In the spring of 1879, Hermann Lau shot two white-winged choughs,Corcorax melanorhamphos, off their nest in Queensland, Australia. He watched asadditional choughs continued to attend the nest, proving that a cooperativegroup shared parental care ( 1). Since then, cooperatively breeding birds havehad a starring role in efforts to explain the evolution of complex animalsocieties. We now know that “helpersat-the-nest”who forgo reproduction areoften relatives of the breeding pair. Genetic payoff is, thus, one of severaladvantages that helpers can gain from their superﬁ cially altruistic behavior (2). On page 1506 of this issue, Feeney et al. ( 3) show that collective defenseagainst brood parasites (see the ﬁgure) can enhance such beneﬁ ts ofcooperation. Why do some bird species cooperate and others do not? Globalanalyses have shown that cooperative breeding (now known from 9% of species) isassociated with a slow pace of life (characterized by high survival rates andlow turnover of breeding territories) ( 4), monogamy (which facilitates kinselection within families) ( 5), and unpredictable environments (such as aridzones) that might favor cooperation as a bet-hedging strategy ( 6). But thesefactors often fail to predict the incidence of cooperation among relatedspecies or within geographical regions ( 7). Feeney et al.’s study is built onthe premise that brood parasitism—reproductive cheating by species such ascuckoos and cowbirds, which exploit other birds to raise their young—is asevere selection pressure on their hosts’ breedingstrategies. Parasitizedparents typically not only lose their current offspring but also waste a wholebreeding season raising a demanding impostor. The best way to avoid parasitismis to repel adult parasites from the nest. Feeney et al. show that socialitycan be pivotal to this process. The authors begin by unfolding a new map. Usingdata compiled by BirdLife International, they show that the global distributionof cooperatively breeding birds overlaps strikingly with that of broodparasites. This overlap need not reﬂ ect a causal relationship: The same unpredictable environments thatfavor cooperation could also favor alternative breeding strategies such asparasitism. However, the authors go on to show that even within geographicalregions rich in both parasites and cooperators—Australia and southern Africa—cooperativebreeders are much more likely than noncooperative species to be targeted bybrood parasites. To determine the reasons for this correlation, Feeney et al.studied cooperative breeding in superb fairy-wrens (Malurus cyaneus) inAustralia. Horsfield’s bronze-cuckoos (Chalcites basalis) should beneﬁ t fromtargeting larger groups of fairy-wrens because more helpers mean faster chickgrowth. Yet, data from a 6-year field study show that in practice, cuckoosrarely experience this advantage, because larger groups of fairywrens much moreeffectively detect and repel egg-laying intrusions by cuckoo females,mobilizing group defenses with a cuckoospeciﬁ c alarm call. Thus, cooperationand parasitism could reciprocally inﬂ uence one another: Cooperators might bemore attractive targets because they make better foster parents, but once exploited by parasites, they are alsobetter able to ﬁ ght back, helping cooperation to persist ( 8). Feeney et al. ﬁnd that superior anticuckoo defenses in larger groups account for 0.2 moreyoung ﬂ edged per season on average than smaller groups—a substantial boostgiven the fairy-wrens’ low annual fecundity. These results show convincinglythat defense against brood parasites augments the beneﬁ ts of helping, promotingthe persistence of cooperation. But as the authors note, they cannot revealwhat caused cooperation to evolve initially. Brood parasitism alone cannotresolve the question of why some birds breed cooperatively. For example,cooperative kingﬁ shers and bee-eaters areheavily parasitized in Africa butnot in Australasia, showing that other advantages of helping behavior are sufﬁcient for cooperation to persist. But we should take parasitism seriously as animportant force in a cooperative life. Indeed, it may provide a mechanismcontributing to the previously discovered global correlates of cooperation (4–6). Some insight into the likely order of evolution might come from furthercomparative predictions. For instance, if cooperation arose fi rst as a defenseagainst parasitism, cooperators may be most prevalent among hosts that relyheavily on repelling adult parasites, rather than on antiparasite strategies atlater reproductive stages, such as egg or chick discrimination ( 9). Incontrast, if parasites target existing cooperators because they providesuperior care, this should be especially true of parasites whose chicks havethe most pressing needs—for instance, those in parasitic families with largebody size relative to their hosts or those whose chicks do not kill host youngand therefore must share their foster parents’ care. Could there be a similarassociation between cooperation and parasitism among other highly socialanimals? Cooperation in mammals clearly persists irrespective of parasitism, giventhat there are no known brood-parasitic mammals (perhaps because it would bediffi cult for a mammal to insert live young into another’s care). Butrepelling parasitic egg-laying intrusions is crucial to many hosts of sociallyparasitic insects and has shaped sophisticated adaptations and counterdefensesfor and against brute force and secrecy ( 10). It will be fascinating toexplore how selection for antiparasitic defense has interacted with monogamyand defensible resources as forces favoring kin-selected cooperation ininvertebrates, touching on an active debate in evolutionary biology. Answers tosuch comparative questions will ultimately be limited by our knowledge ofnatural history. The work by Feeney et al. is testament to the evolutionaryinsights enabled by careful long-term fi eld studies, together with thecumulative legacy of those naturalists who made the unglamorous effort torecord and publish observations of real animals in real places.。

材料：The Official SAT Study Guide试卷：2页数：457题号：18Questions 11-21 are based on the following passage and supplementary material. This passage is adapted from Iain King, “Can Economics Be Ethical?”©2013 by Prospect Publishing.These human quirks mean we can never make purely “rational” decisions. A new wave of behavioral economists, aided by neuroscientists, is trying to understand our psychology, both alone and in groups, so they can anticipate our decisions in the marketplace more accurately. But psychology can also help us understand why we react in disgust at economic injustice, or accept a moral law as universal. Which means that the relatively new science of human behavior might also define ethics for us. Ethical economics would then emerge from one of the least likely places: economists themselves.18. The main idea of the final paragraph is thatA) human quirks make it difficult to predict people’s ethical decisions accurately.B) people universally react with disgust when faced with economic injustice.C) understanding human psychology may help to define ethics in economics.D) economists themselves will be responsible for reforming the free market.答案: C答案解析: 本题问的是结尾段(lines 83-88) 的中心思想。

2016新SAT第一份样卷第三篇阅读翻译

新SAT样卷第三篇阅读文章完整翻译南京/常州/上海携斐教育College B oard于2015年3月第一次放出了完整的新SAT考卷，携斐国际教育第一时间组织教师和高分学员（南外/南师等一批已经被美国名校录取的高分学员）对这套真题进行了翻译和分析，会陆续放出。

以下是该套新SAT真题第三篇文章的完整翻译，由南外本部高三，2015年被UIUC大学（全美排名15）录取的携斐教育高分学员谢芷馨同学翻译，在保证大意的情况下，难免有些小差错，欢迎提出宝贵意见。

Questions 20-28 are based on the followingpassage and supplementary material.This passage is adapted from Tina Hesman Saey, “Lessons from the Torpid.” ©2012 by Society for Science & the Public.Understanding how hibernators, includingground squirrels, marmots and bears, survive theirlong winter’s naps may one day offer solutions for problems such as heart disease, osteoporosis and muscular dystrophy.Nearly everything about the way an animal’s bodyworks changes when it hibernates, and preparationsstart weeks or months in advance. The first order of business is to fatten up.“Fat is where it’s at for a hibernator,” saysMatthew Andrews, a molecular biologist at the University of Minnesota Duluth who studies 13-lined ground squirrels. “You bring your own lunch with you.” Packing lunch is necessary because the animalsgo on the world’s strictest diet during the winter, surviving entirely off their white fat. “They have their last supper in October; they don’t eat again until March,” Andrews says.Bigger fat stores mean a greater chance ofsurviving until spring. “If they go in really chunky,nice and roly-poly, that’s going to be a good hibernator,” he says.Bears also watch their waistlines expand in themonths before settling in for the season. The brown bears cardiologist Ole Fröbert studies pack on the pounds by chowing down on up to 40 kilograms of blueberries a day. Such gluttony among humanscould have severe consequences: Obesity isassociated with a greater risk of heart attack and diabetes, among other ailments.To see how fattening up affects Scandinavian brown bears, Fröbert and his colleaguesventured into the wilds of Sweden following signals given off by radio transmitters or GPS devices on tagged bears.Bears can be dangerous close-up. Even hibernating bears can rouse to action quickly, so scientists tracking down bears in the winter use darts to tranquilize the animals from a distance. Scientists studying the bears in the summer tranquilize them from a helicopter.Once a bear is under the tranquilizer’s influence (which takes about five minutes), the scientists have 60 minutes max to get the animal from its den, weigh and measure it, draw blood samples and do minor surgeries to collect fat and other tissues. The bear is returned to its den by minute 61.Precious materials collected during thishigh-pressure encounter need to be analyzed within 24 hours, so the researchers often test for levels of cholesterol or certain proteins in the blood while working in the snow or at a nearby research station.A pilot sometimes flies samples from field sites to a lab in Denmark in order to meet the deadline,Fröbert says. Samples such as bones and arteries that can’t be collected from live bears come from bears killed by hunters during the legal hunting season. Recent analyses revealed that Scandinavian brown bears spend the summer with plasma cholesterol levels considered high for humans; those values then increase substantially for hibernation, Fröbert and his colleagues reported. These “very, very fat” bears with high cholesterol also get zero exercise during hibernation. Lolling about in the den pinches off blood vessels, contributing to sluggish circulation. “That cocktail would not be advisable in humans,”Fröbert says. It’s a recipe for hardened arteries,putting people at risk for heart attacks and strokes. Even healthy young adult humans can developfatty streaks in their arteries that make the blood vessels less flexible, but the bears don’t build up such artery-hardening streaks. “Our bears, they had nothing,” Fröbert says. It’s not yet clear how the bears keep their arteries flexible, but Fröbert hopes to find some protective molecule that could stave off hardened arteries in humans as well.20. The passage is written from the perspective ofsomeone who isA) actively involved in conducting hibernator research.B) a participant in a recent debate in the field of cardiology.C) knowledgeable about advances in hibernator research.D) an advocate for wildlife preservation.21. It is reasonable to conclude that the main goal of the scientists conducting the research described in the passage is toA) learn how the hibernation patterns of bears and squirrels differ.B) determine the role that fat plays in hibernation.C) illustrate the important health benefits ofexercise for humans.D) explore possible ways to prevent human diseases.22. Which choice provides the best evidence for the answer to the previous question?A) Lines 1-5 (“Understanding . . . dystrophy”)B) Lines 10-13 (“Fat . . . squirrels”)C) Lines 31-35 (“To . . . bears”)D) Lines 42-46 (“Once . . . tissues”)23.What main effect do the quotations by Andrews in lines 10-18 have on the tone of the passage?A) They create a bleak tone, focusing on the difficulties hibernators face during the winter.B) They create a conversational tone, relating scientific information in everyday language.C) They create an ominous tone, foreshadowing the dire results of Andrews’s research.D) They create an absurd tone, using images of animals acting as if they were human.24. As used in line 19, “stores” most nearly meansA) preservatives.B) reserves.C) stacks.D) shelters. 25. Based on the passage, what is Fröbert’s hypothesis regarding why bears’ arteries do not harden during hibernation?A) The bears’ increased plasma cholesterol causes the arteries to be more flexible.B) Sluggish circulation pinches off the blood vessels rather than hardening the arteries.C) Bears exercise in short, infrequent bursts during hibernation, which staves off hardened arteries.D) Bears possess a molecule that protects against hardened arteries.26.Which choice provides the best evidence for the answer to the previous question?A) Lines 19-20 (“Bigger . . . spring”)B) Lines 24-27 (“The brown . . . day”)C) Lines 69-72 (“Even . . . streaks”)D) Lines 73-76 (“It’s . . . well”)27.What information discussed in paragraph 10 (lines 58-68) is represented by the graph?A) The information in lines 58-62 (“Recent . . . reported”)B) The information in lines 62-64 (“These . . . hibernation”)C) The information in lines 64-65 (“Lolling . . . circulation”)D) The information in lines 67-68 (“It’s . . . strokes”)28. Which statement about the effect of hibernation on the seven bears is best supported by the graph?A) Only one of the bears did not experience an appreciable change in its total plasma cholesterol level.B) Only one of the bears experienced a significant increase in its total plasma cholesterol level.C) All of the bears achieved the desirable plasma cholesterol level for humans.D) The bear with the lowest total plasma cholesterol level in its active state had the highest totalplasma cholesterol level during hibernation.对于像松鼠，土拔鼠和熊这样的冬眠动物是如何度过他们漫长的冬眠的了解，或许有一天会为像心脏病，骨质疏松和肌肉萎缩症等问题提供解决方案。

新SAT官方指南阅读第三篇全解析

新SAT官⽅指南阅读第三篇全解析新SAT官⽅指南阅读第三篇全解析This passage is adapted from J.D.Watson and F.H.C.Crick,“Genetical Implications of the Structure of Deoxyribonucleic Acid.”○C1953by Nature Publishing Group.Watson and Crick deduced the structure of DNA using evidence from Rosalind Franklin and R.G.Gosling’s X-ray crystallography diagrams of DNA and from Erwin Chargaff’s data on the base composition of DNA.The chemical formula of deoxyribonucleic acid(DNA)is now well established the molecule isa very long chain,the backbone of which consists of a regular alternation of sugar and phosphategroups.To each sugar is attached a nitrogenous base,which can be of four different types.Two of the possible bases-adenine and guanine-are purines,and the other two-thymine and 5cytosine-are pyrimidines.So far as is known,the sequence of bases along the chain is irregular.The monomer unit,consisting of phosphate,sugar and base,is known as a nucleotide.The first feature of our structure which is of biological interest is that it consists not of one chain,but of two.These two chains are both coiled around a common fiber axis.It has often been assumed that since there was only one chain in the structural unit.However,the density, 10taken with the X-ray evidence,suggests very strongly that there are two.The other biologically important feature is the manner in which the two chains are held together.This is done by hydrogen bonds between the bases.The bases are joined together in pairs,a single base from one chain being hydrogen-bonded to a single base from the other.Theimportant point is that only certain pairs of bases will fit into the structure.One member of a pair 15must be a purine and the other a pyrimidine in order to bridge between the two chains.If a pair consisted of two purines for example,there would not be room for it.We believe that the bases will present almost entirely in their most probable forms.If this is true,the conditions for forming hydrogen bonds are more restrictive,and the only pairs of bases possible are:adenine with thymine,and guanine with cytosine.Adenine,for example,can occur 20on either chain;but when it does,its partner on the other chain must always be thymine.The phosphate-sugar backbone of our model is completely regular,but any sequence of the pairs of bases can fit into the structure.It follows that in a long molecule many different permutations are possible,and it therefore seems likely that the precise sequence of bases is the code which carries the genetical information.If the actual order of the bases on one of the pair of 25chains were given,one could write down the exact order of the bases on the other one,because of the specific pairing.Thus one chain is,as it were,the complement of the other,and it is this feature which suggests how the deoxyribonucleic acid molecule might duplicate itself.The table shows,for various organisms,the percentages of each of the four types of nitrogenous bases in that organism’s DNA.22.The authors use the word“backbone”in lines2and21to indicate that(A)only very long chains of DNA can be taken from an organism with a spinal column.(B)the main structure of a chain in a DNA molecule is composed of repeating units.(C)a chain in a DNA molecule consists entirely of phosphate groups or of sugars.(D)nitrogenous bases form the main structural unit of DNA正确答案：B分析:⽂章2-4⾏将DNA描述成⼀个长链条，主⼲由糖和磷酸盐交替组成。

纽约的风雪阅读题答案

纽约的风雪阅读题答案本文提供纽约的风雪阅读题的答案，并对相关要点进行解析。

该阅读题选自新SAT官方指南。

文本原文下面是阅读题的文本原文：New York is famous for its snowy and cold winters. Every year, the city is blanketed with snow several times. When snow falls, the city is transformed. The snow piles up on the sidewalks, and people must trudge through it to get around. Large piles of snowplowed snow form on the sides of the roads.Despite the snow, New York never completely stops. The subways continue to run, and people still brave the weather to shop, work, and go to school. In fact, many people enjoy the winter weather. They ice-skate in Central Park and go skiing and snowboarding in the mountains nearby.However, the snow does make it difficult to get around. Cars have trouble driving through the snow, and sometimes they slide on the icy roads. This can cause traffic jams and accidents. People also have to be careful when walking on the snow and ice. They can slip and fall.Overall, winter in New York can be tough, but it can also be beautiful and fun.答案下面是该题的答案：1.What is something that happens to New York each year?答案： The city is blanketed with snow several times.解析：第一句话就提到了 New York 有大雪，并且每年都会下降好几次。

新sat阅读题型图表题解析

新sat阅读题型图表题解析随着新SAT考纲、样题、官方指南等的陆续发布，新SAT题目揭开了神秘面纱，其中阅读版块增加了全新的题型—循证题和图表题，本篇文章就来详细解读一下图表题到底是什么。

题目设置意义美国的新课标中(CCSS)，给全美国的高中生阅读能力提出了10条明确标准，其中第7条为“Integrate and evaluate content presented in diverse formats and media, including visually and quantitatively, as well as words.”看似高大上，其实是要求学生能够看懂各种形式的信息的，比如视频的、图片的、图表的、文字的等等。

而抱美国新课标大腿的新SAT考试，在考纲中的阅读版块也要求了这样一个能力点“Analyzing quantitative information: The students will analyze information presented quantitatively in such forms as graphs, tables, and charts and/or relate that information to information presented in text.”意思就是你需要看懂各种图表(柱形哒，饼形哒，表格哒等等)，还得会根据图表和文章内容来作答……为什么美国新课标和新SAT都这么要求呢?其实是想让学生培养分析数据及整合信息的能力，以便在大学能更高效地学习。

大家听说过，在美国大学学习中，学生需要大量搜集、阅读和理解各种形式的文章和信息，通过这一过程来学习和理解知识。

但别怕，其实我们在初高中的时候也接触到了，想想我们学习过的数学、地理、物理、化学等学科知识，虽然不堪回首，但课本上各种图表、图片和数据，与课本中的知识相结合，让我们高冷的课本“暖”了起来。

为了避免偏见，经常选择涉及美国少数民族或移民类的文章。

新SAT阅读文章的选择除了保留目前SAT的长双(两篇题材相近的较长的文章构成一组)文章以外，其他文章的选择类似其竞争对手ACT的文章选择，各篇文章之间的长度(500-750词/篇)比较均衡，文章后面的问题数(10或11个)也基本一致。

而且，各类题材(文学、历史/社会研究、科学)文章所占比例每次考试都固定，不象目前考试中各类题材文章的比例经常出现变化。

《新SAT官方指南》的样题和四套练习题都把文学题材(通常为小说或故事)排在第一篇文章，而在目前的考试中小说或故事在试卷中的位置不确定。

由于阅读量大，新SAT阅读的处理对于速度有较高要求，而考生对于不同题材的文章的阅读速度不同。

但是，由于新SAT阅读文章的做题时间是作为一个整体提供的，考生可以根据自己的情况以及文章的难易选择阅读文章的顺序——先处理哪篇，后处理哪篇。

新SAT阅读小说和科学类文章解析

新SAT阅读小说和科学类文章解析小说和科学类文章，作为新SAT阅读中考察的两大文体，对我们取得高分很重要。

能理解两类文体的特征、写作目的和写作思路，同时掌握出题的特点对考生快速理解文本，对做题目有很重要的帮助。

阅读部分作为重点和难点，一直饱受关注，多变的文章类型也一直在困扰考生们。

小说跌宕起伏一波三折，科学的严谨循证都让考生们晕头转向!到底该怎么面对风格多样的文本呢?让我们通过新SAT OG的官方指南，一起来分析一下文章类型和各自的做题策略。

OG中在对文章类型进行介绍的时候，按照写作目的把阅读部分的文章分成三个类型：1)讲故事或者经历(telling a story, recounting an experience);2)传递信息观点或者解释概念观点(present new information and ideas or explain a process or concept);3)论述型文章(argument)。

其中的1)和2)两类分别对应小说和自然科学的文体特征。

本篇文章里我们来对这两篇文章的理解方式和做题思路稍作比较和解析。

小说作为一种文学题材，本质其实就是讲故事。

与基于事实和经历的回忆录或者自传不同的是，小说的故事是虚构和想象的(可能有人物原型)。

当我们在读故事的时候，关注的核心点主要是故事的中的人物(角色)和情节(事件)。

在小说中，经常通过对人物角色的塑造来推动情节的发展，通过情节中人物的行为、人物之间的矛盾和关系进一步塑造人物。

人物和情节的相互支撑通常是小说的理解的核心。

新SAT阅读汇总对小说的考察也是从这个角度出发，多数题目都是要求考生分析角色的心理、行为，角色之间的关系，以及故事情节。

在阅读中把握人物特征和人物关系这条线索对我们快速理解情节都有很大的帮助。

相比于小说，自然科学甚至包括社会科学以及其他议论文，核心其实都是观点。

自然科学和社会科学中，对新的理论，观点，假说进行解释，之后通过相关的实验数据或者观察数据，支持观点。

And how can woman be expected to co-operate unless she know why she ought to be virtuous? Unless freedom strengthen her reason till she comprehend her duty, and see in what manner it is connected with her real good? (选自新版SAT OG test 3 passage 3) As used in line 50, “reason”most nearly meansA) motiveB) sanityC) intellectD) explanation首先，先理解文章的主旨和态度：这是双篇文的第二篇，前言说明此文是Wollstonecraft的Vindication of the Right of Woman. 阐述的观点女性应该平等地接受和男性一样的国民教育。

其次，句子大意为：“怎么可以期望女性做到合作，除非，她懂得为什么她应该是virtuous(品德高尚的)?除非，自由加强了她的reason，直到她理解了她的职责，同时以什么方式可以看到这关乎于她真正的好处?”再看，句子逻辑：两个unless并列，freedom strengthen her reason till she comprehend her duty平行于she know why she ought to bevirtuous。

所以是strengthened reason足够让女性comprehend/ know她的职责和为什么她要高尚。
