　　考研英語(yǔ)閱讀理解專(zhuān)項(xiàng)試題及答案 1

　　Historians have only recently begun to note the increase in demand for luxury goods and services that took place in eighteenth-century England. McKendrick has explored the Wedgwood firm’s remarkable success in marketing luxury pottery; Plumb has written about the proliferation of provincial theater, musical festivals, and children’s toys and books. While the fact of this consumer revolution is hardly in doubt, three key questions remain: Who were the consumers? What were their motives? And what were the effects of the new demand for luxuries?

　　An answer to the first of these has been difficult to obtain. Although it has been possible to infer from the goods and services actually produced what manufacturers and servicing trades thought their customers wanted, only a study of relevant personal documents written by actual consumers will provide a precise picture of who wanted what. We still need to know how large this consumer market was and how far down the social scale the consumer demand for luxury goods penetrated. With regard to this last question, we might note in passing that Thompson, while rightly restoring laboring people to the stage of eighteenth-century English history, has probably exaggerated the opposition of these people to the inroads of capitalist consumerism in general; for example, laboring people in eighteenth-century England readily shifted from home-brewed beer to standardized beer produced by huge, heavily capitalized urban breweries.

　　To answer the question of why consumers became so eager to buy, some historians have pointed to the ability of manufacturers to advertise in a relatively uncensored press. This, however, hardly seems a sufficient answer. Mckendrick favors a Veblem model of conspicuous consumption stimulated by competition for status. The “middling sort” bought goods and services because they wanted to follow fashions set by the rich. Again, we may wonder whether this explanation is sufficient. Do not people enjoy buying things as a form of self-gratification? If so, consumerism could be seen as a product of the rise of new concepts of individualism and materialism, but not necessarily of the frenzy for conshttps://p.9136.com/28petition.

　　Finally, what were the consequences of this consumer demand for luxuries? McKendrick claims that it goes a long way toward explaining the coming of the Industrial Revolution. But does it? What, for example, does the production of high-quality pottery and toys have to do with the development of iron manufacture or textile mills? It is perfectly possible to have the psychology and reality of a consumer society without a heavy industrial sector.

　　That future exploration of these key questions is undoubtedly necessary should not, however, diminish the force of the conclusion of recent studies: the insatiable demand in eighteenth-century England for frivolous as well as useful goods and services foreshadows our own world.

　　1. In the first paragraph, the author mentions McKendrick and Plumb most probably in order to

　　[A] contrast their views on the subject of luxury consumerism in eighteenth-century England.

　　[B] indicate the inadequacy of historiographical approaches to eighteenth-century English history.

　　[C] give examples of historians who have helped to establish the fact of growing consumerism in eighteenth-century England.

　　[D] support the contention that key questions about eighteenth-century consumerism remain to be answered.

　　2. Which of the following items, if preserved from eighteenth-century England, would provide an example of the kind of documents mentioned in lines 3-4, paragraph 2?

　　[A] A written agreement between a supplier of raw materials and a supplier of luxury goods.

　　[B] A diary that mentions luxury goods and services purchased by its author.

　　[C] A theater ticket stamped with the date and name of a particular play.

　　[D] A payroll record from a company that produced luxury goods such as pottery.

　　3. According to the text, Thompson attributes to laboring people in eighteenth-century England which of the following attitudes toward capitalist consumerism?

　　[A] Enthusiasm.

　　[B] Curiosity.

　　[C] Ambivalence.

　　[D] Hostility.

　　4. In the third paragraph, the author is primarily concerned with

　　[A] contrasting two theses and offering a compromise.

　　[B] questioning two explanations and proposing a possible alternative to them.

　　[C] paraphrasing the work of two historians and questioning their assumptions.

　　[D] examining two theories and endorsing one over the other.

　　5. According to the text, eighteenth-century England and the contemporary world of the text readers are

　　[A] dissimilar in the extent to which luxury consumerism could be said to be widespread among the social classes.

　　[B] dissimilar in their definitions of luxury goods and services.

　　[C] dissimilar in the extent to which luxury goods could be said to be stimulant of industrial development.

　　[D] similar in their strong demand for a variety of goods and services.

　　直到最近，史學(xué)家們才發(fā)現(xiàn)在十八世紀(jì)的英國(guó)，對(duì)豪華奢侈商品和服務(wù)的需求出現(xiàn)增長(zhǎng)的現(xiàn)象。麥克德瑞克研究了韋奇伍德公司在營(yíng)銷(xiāo)豪華陶制品方面的極大成功;而普拉姆也著文論述了地方劇院、音樂(lè)節(jié)目以及兒童玩具和書(shū)籍激增的情形。盡管這場(chǎng)消費(fèi)者革命的事實(shí)幾乎毋庸置疑，但仍有三個(gè)關(guān)鍵的問(wèn)題尚待解決：消費(fèi)者是些什么人?他們的動(dòng)機(jī)是什么?以及這種對(duì)奢侈品的新需求的社會(huì)影響是什么?

　　關(guān)于第一問(wèn)題的答案是很難獲得的。盡管它可能從制造商和服務(wù)行業(yè)認(rèn)為消費(fèi)者想要什么而實(shí)際制造的商品和提供的服務(wù)中推知，但只有對(duì)實(shí)際消費(fèi)者的相關(guān)私人資料的研究才能提供一種“誰(shuí)想要什么”的精確狀況。我們?nèi)匀恍枰肋@種消費(fèi)市場(chǎng)到底有多大，以及消費(fèi)者對(duì)奢侈商品的需求向下滲透到社會(huì)的什么層次。對(duì)最后一個(gè)問(wèn)題而言，我們應(yīng)當(dāng)注意到，在過(guò)去，湯姆遜雖然正確恢復(fù)了勞動(dòng)人民在十八世紀(jì)英國(guó)歷史舞臺(tái)上的地位，但整體而言可能夸大了他們對(duì)資本主義消費(fèi)方式侵蝕的抵抗情緒。例如，十八世紀(jì)英國(guó)的勞動(dòng)人民迅速?gòu)募裔劦钠【妻D(zhuǎn)而飲用由那些大規(guī)模、高度資本化的城市釀酒廠生產(chǎn)的標(biāo)準(zhǔn)化啤酒。

　　為了回答消費(fèi)者為什么變得那么急于購(gòu)物這一問(wèn)題，一些史學(xué)家指出，這是因?yàn)橹圃焐虃兛梢栽跓o(wú)需審查的報(bào)刊上刊登廣告。然而，這似乎并不是個(gè)理由充分的答案。麥克德瑞克贊成維布倫模型，即由社會(huì)地位的競(jìng)爭(zhēng)而引起的一種引人注目的消費(fèi)�！爸挟a(chǎn)階級(jí)”購(gòu)買(mǎi)優(yōu)質(zhì)商品和服務(wù)，是因?yàn)樗麄兿胱冯S由富人建立的消費(fèi)時(shí)尚。我們可能再次懷疑這種解釋是否充足。難道人們喜愛(ài)購(gòu)物不是一種自我滿(mǎn)足的`形式嗎?如果是這樣，那么上述消費(fèi)主義可以被看做是一種個(gè)人主義和物質(zhì)主義新興概念的產(chǎn)物，而不一定是瘋狂進(jìn)行引人注目的競(jìng)爭(zhēng)的結(jié)果。

　　最后，這種消費(fèi)者對(duì)奢侈品的需求所導(dǎo)致的后果又是什么呢?麥克德瑞克聲稱(chēng)，這將極為有助于解釋工業(yè)革命的到來(lái)。但事實(shí)果真如此嗎?例如，高質(zhì)量的陶制品和玩具與鋼鐵制造和紡織工廠的發(fā)展有什么關(guān)系呢?即使沒(méi)有重工業(yè)的存在，消費(fèi)社會(huì)在心理上和現(xiàn)實(shí)上都是完全可能存在的。

　　然而，對(duì)這些關(guān)鍵問(wèn)題的進(jìn)一步探究毫無(wú)疑問(wèn)是需要的，而且不應(yīng)當(dāng)減弱近期研究所得結(jié)論的說(shuō)服力：十八世紀(jì)英國(guó)對(duì)那些有用和瑣碎商品及服務(wù)的不知足的需求預(yù)示了我們目前的這個(gè)世界的特征。

　　考研英語(yǔ)閱讀理解專(zhuān)項(xiàng)試題及答案 2

　　The intensive work of materials scientists and solid-state physicists has given rise to a class of solids known as amorphous metallic alloys or glassy metals. There is a growing interest among theoretical and applied researchers alike in the structural properties of these materials.

　　When a molten metal or metallic alloy is cooled to a solid, a crystalline structure is formed that depends on the particular alloy composition. In contrast, molten nonmetallic glass-forming materials when cooled do not assume a crystalline structure, but instead retain a structure somewhat like that of the liquid — an amorphous structure. At room temperature the natural long-term tendency for both types of materials is to assume the crystalline structure. The difference between the two is in the kinetics or rate of formation of the crystalline structure which is controlled by factors such as the nature of the chemical bonding and the ease with which atoms move relative to each other. Thus, in metals, the kinetics favors rapid formation of a crystallines structure whereas in nonmetallic glasses the rate of formation is so slow that almost any cooling rate is sufficient to result in an amorphous structure. For glassy metals to be formed, the molten metal must be cooled extremely rapidly so that crystallization is suppressed.

　　The structure of glassy metals is thought to be similar to that of liquid metals. One of the first attempts to model the structure of a liquid was that by the late J. D. Bernal of the University of London, who packed hard spheres into a rubber vessel in such a way as to obtain the maximum possible density. The resulting dense, random-packed structure was the basis for many attempts to model the structure of glassy metals.

　　Calculations of the density of alloys based on Bernal-type models of the alloys metal component agree fairly well with the experimentally determined values from measurements on alloys consisting of a noble metal together with a metalloid such as alloys of palladium and silicon or alloys consisting of iron phosphors, and carbon, although small discrepancies remained. One difference between real alloys and the hard spheres area in Bernal models is that the components of an alloy have different size, so that models based on two sizes of spheres are more appropriate for a binary alloy for example. The smaller metalloid atoms of the alloys might fit into holes in the dense random-packed structure of the larger metal atoms.

　　One of the most promising properties of glassy metals is their high strength combined with high malleability. In usual materials, one finds an inverse relation between the two properties, whereas for many practical applications simultaneous presence of both properties is desirable. One residual obstacle to practical applications that is likely to be overcome is the fact that glassy metals will crystallize at relatively low temperatures when heated slightly.

　　1. The author is primarily concerned with discussing

　　[A] crystalline solids and their behavior at different temperatures.

　　[B] molten materials and the kinetics of the formation of their crystalline structure.

　　[C] glassy metals and their structural characteristics.

　　[D] metallic alloys and problems in determining their density.

　　2. The author’s attitude toward the prospects for the economic utilization of glassy metals is one of

　　[A] disinterest.

　　[B] impatience.

　　[C] optimism.

　　[D] apprehension.

　　3. According to the text, which of the following determines the crystalline structure of a metallic alloy?

　　[A] At what rate the molten alloy is cooled.

　　[B] How rapid the rate of formation of the crystalline phase is.

　　[C] How the different-sized atoms fit into a dense random-packed structure.

　　[D] What the alloy consists of and in what ratios.

　　4. Which of the following best describes the relationship between the structure of liquid metals and the structure of glassy metals, as it is presented in the text?

　　[A] The latter is an illustrative example of the former.

　　[B] The latter is a large-scale version of the former.

　　[C] The former is a structural elaboration of the latter.

　　[D] The former is a fair approximation of the latter.

　　5. It can be inferred from the text that, theoretically, molten nonmetallic glasses assume a crystalline structure rather than an amorphous structure only if they are cooled

　　[A] very evenly, regardless of the rate.

　　[B] rapidly, followed by gentle heating.

　　[C] very slowly.

　　[D] to room temperature.

　　材料科學(xué)家和固體物理學(xué)家的深入研究已促進(jìn)了一種固體物質(zhì)的出現(xiàn)，這類(lèi)固體被稱(chēng)為非晶體金屬合金，也就是玻璃金屬。理論和應(yīng)用研究者對(duì)這些材料的結(jié)構(gòu)特性的興趣正與日俱增。

　　當(dāng)一種熔化的金屬和金屬合金冷卻成固體時(shí)，依賴(lài)于特定的合金成份將形成各種晶體結(jié)構(gòu)。相比之下，熔化的非金屬、玻璃類(lèi)材料在冷卻后將不會(huì)形成晶體結(jié)構(gòu)，而是保留一點(diǎn)類(lèi)似于液體的非晶體結(jié)構(gòu)，在室溫條件下，兩類(lèi)材料的自然的長(zhǎng)期傾向都形成了晶體結(jié)構(gòu)。它們之間的不同在于動(dòng)態(tài)性，即形成晶體結(jié)構(gòu)的速度。這種動(dòng)態(tài)性受下述兩種因素控制：化學(xué)結(jié)合的性質(zhì)和分子之間相互運(yùn)動(dòng)的自由程度。由此，對(duì)金屬而言，動(dòng)態(tài)歷程有利于晶體結(jié)構(gòu)的快速形成;而對(duì)非金屬來(lái)說(shuō)，這種形成速度非常慢，以至于任何自然冷卻速度都足以形成一種非晶體結(jié)構(gòu)。要想形成玻璃金屬，熔化的金屬必須以極快的速度冷卻，以抑制晶體的形成。

　　人們認(rèn)為玻璃金屬的結(jié)構(gòu)與液態(tài)金屬的結(jié)構(gòu)類(lèi)似。創(chuàng)建這種液體結(jié)構(gòu)模型的第一次嘗試是已故的倫敦大學(xué)的J. D.鮑納爾進(jìn)行的，他將堅(jiān)硬的球體盡可能多地填塞進(jìn)一個(gè)橡膠容器中，以便得到一種最大可能的密度。這個(gè)密度結(jié)果以及隨機(jī)填塞結(jié)構(gòu)以后便成為試圖建立玻璃金屬結(jié)構(gòu)模型的基礎(chǔ)。

　　基于鮑納爾模型，由合成金屬的成份組成對(duì)合金密度的計(jì)算結(jié)果與實(shí)驗(yàn)測(cè)得的結(jié)果相當(dāng)?shù)匚呛希?dāng)然一些細(xì)微的差異仍然存在。實(shí)驗(yàn)結(jié)果是通過(guò)測(cè)量由一種重金屬和類(lèi)金屬組成的合金得到的，如鈀和硅的合金，或鐵磷和碳組成的合金。實(shí)際的合金和鮑納爾模型所用的球體之間的差別在于合金的成份有不同的體積大小，因此，基于兩種大小的球體的模型更適合于兩類(lèi)物質(zhì)的合金。合金中非金屬的小原子可能填進(jìn)由大原子隨機(jī)填塞形成的緊密結(jié)構(gòu)中。

　　玻璃金屬最有前景的一個(gè)特征是高強(qiáng)度與高延伸性的結(jié)合。在常見(jiàn)的晶體材料中，這兩種特性一般是成反比的，但人們渴望它們同時(shí)存在。在實(shí)際用途中可能還有一個(gè)問(wèn)題急待解決，即當(dāng)玻璃金屬在相對(duì)的低溫下慢慢加熱時(shí)，它會(huì)逐漸變?yōu)榫w結(jié)構(gòu)。

　　考研英語(yǔ)閱讀理解專(zhuān)項(xiàng)試題及答案 3

　　The complications frequently accompanying diabetes, such as impairment of vision and of kidney function, are now thought to result from the lack of continuous control of blood glucose concentrations. The healthy pancreas, in response to increases in blood glucose concentration, releases small quantities of insulin throughout the day and thereby maintains the concentration within physiological limits (nomoglycemia). But the diabetic generally receives only one large dose daily. The diabetic’s blood glucose concentration can thus fluctuate greatly during the interval between doses, and it has been suggested that the complication result from the periods of high concentrations of blood glucose (hyperglycemia). Many investigators thus believe that restoration of normoglycemia might halt the progression of such complications and perhaps even reverse them.

　　There are three primary techniques that have been investigated for restoration of normoglycemia. They are: transplantation of whole, healthy pancreases; transplantation of islets of Langerthan, that portion of the pancreas that actually secretes insulin, and implantation of artificial pancreases. There has, in fact been a great deal of success in the development of these techniques and each seems, on the whole, promising. Nonetheless, it will undoubtedly be many years before any one of them is accepted as a treatment for diabetes.

　　To many people, the obvious approach would seem to be simply to transplant pancreases from cadavers in the same manner that kidneys and other organs are routinely transplanted. That was the rationale in 1966 when the first recorded pancreas was performed. Between 1960 and 1975, there were forty-six pancreas transplants in forty-five other patients in the United States and five other countries. But only one of these patients is still alive with a functioning graft and surgeons have found that the procedure is not simple as they once thought.

　　The surviving patient has required no insulin since the operation. Another patient survived 638 days without requiring insulin. And one patient survived a transplantation for more than a year, but died when he chose not to take immunosuppressive drugs. These results, though meager, suggest that the procedure has the potential for success.

　　The rest of the patients, however, either rejected the transplant or died within a short period. There does not appear to be any technical problem with the procedure. Rather, most of the patients were already so severely debilitated by the complications of diabetes that they could not withstand the surgery and the immunosuppressive regimen required to prevent rejection. More than half of the patients, furthermore, also required a kidney transplant. Most investigators now agree that the simultaneous transplantation of both organs is too great a shock to the patient and greatly increases the total risk.

　　1. Which of the following best states one of the main conclusions of the text?

　　[A] Although the techniques for pancreas transplants appear to be theoretically correct, there are problems that must be solved before the operation can be used as a treatment for diabetes.

　　[B] Although the techniques for pancreas transplants are still being developed, the experimental results show that the operation will be a successful treatment for diabetes in the near future.

　　[C] Although pancreas transplants are reliable, many diabetics are reluctant to undergo the operation because of the side effects of immunosuppressive drugs.

　　[D] Although pancreas transplants alone are not generally successful, the operation can be used in conjunction with other procedures to treat diabetes.

　　2. According to the text, widely spaced doses of insulin can cause

　　[A] reversal of normal kidney function.

　　[B] delay in the onset of diabetes.

　　[C] radical changes in the concentration of blood glucose.

　　[D] restoration of normoglycemia.

　　3. According to the text, a periodic high concentration of blood glucose in diabetics is a possible cause of

　　[A] deterioration of the pancreas.

　　[B] damage to the eyes and kidneys.

　　[C] rejection of transplanted organs.

　　[D] inadequate secretion of insulin.

　　4. It can be inferred from the text that one of the important contributing causes of the failure of most pancreas transplants has been the

　　[A] reluctance of patients to cooperate with physicians.

　　[B] imperfect techniques used in the operation.

　　[C] scarcity of immunosuppressive drugs.

　　[D] weakened condition of the patients.

　　5. The text suggests that the author considers the data concerning the success of pancreas transplants to be

　　[A] invalid.

　　[B] indirect.

　　[C] inaccurate.

　　[D] insufficient.

　　通常與糖尿病相伴的并發(fā)癥，如視力和腎功能的損害，現(xiàn)在被認(rèn)為是由于無(wú)法連續(xù)控制血液中的葡萄糖濃度所導(dǎo)致的。健康的胰臟，在血糖濃度增加時(shí)，會(huì)在整個(gè)白天不斷地釋放出少量的胰島素，從而使血糖濃度維持在生理限度之內(nèi)(正常血糖量)。但是糖尿病患者一般是每天得到一次大劑量胰島素的注射。這樣在兩次注射之間，糖尿病患者的血糖濃度會(huì)發(fā)生很大波動(dòng)，而且目前已被指出，并發(fā)癥可能就是源于這些高血糖濃度時(shí)期(高血糖)。因此，許多研究人員相信，恢復(fù)正常的血糖濃度或許能阻止這些并發(fā)癥的發(fā)展，并進(jìn)而可能減輕并發(fā)癥。

　　為了恢復(fù)正常的血糖濃度，已對(duì)三種主要的技術(shù)進(jìn)行了研究。它們分別是：健康胰臟的整個(gè)移植;胰島部分的移植，胰島是胰腺中實(shí)際分泌胰島素的部分;以及人造腺的移植。事實(shí)上，這些技術(shù)的發(fā)展都獲得了成功，而且從整體上講，每種技術(shù)都大有希望。然而，毫無(wú)疑問(wèn)地，在任何一種技術(shù)被接受用作糖尿病患者的治療手段之前，還會(huì)有很多年的時(shí)間。

　　對(duì)多數(shù)人而言，顯而易見(jiàn)的方法看來(lái)可能是從尸體中移植胰腺，就象移植腎臟和其它器官那樣。這便是1966年第一例胰腺移植手術(shù)的理論基礎(chǔ)。在1966年至1975年間，在美國(guó)和另外五個(gè)國(guó)家，共有45名其它病人進(jìn)行了46例胰腺移植手術(shù)。但目前，只有其中一個(gè)病人尚在人世，而且移植的胰腺功能健全。因此，手術(shù)醫(yī)生們發(fā)現(xiàn)，手術(shù)過(guò)程并不像他們先前想象的那么簡(jiǎn)單。

　　幸存的病人從那次手術(shù)之后不再需要注射胰島素。另一個(gè)病人在不需要注射胰島素的情況下活了638天。還有一名病人在移植之后存活了一年，但他決定不服用免疫藥物之后就死去了。這些結(jié)果，盡管為數(shù)不多，可也表明了手術(shù)過(guò)程有潛在成功的可能。

　　然而，其余的病人或者出現(xiàn)排異反應(yīng)，或者在很短一段時(shí)期后死去。在手術(shù)過(guò)程中，看起來(lái)是不存在任何技術(shù)問(wèn)題的。不過(guò)，大多數(shù)的病人都由于糖尿病的并發(fā)病已經(jīng)很衰弱，以至于無(wú)法經(jīng)受手術(shù)和為防止排異反應(yīng)所需的免疫抑制療程。另外，一大半病人還需要進(jìn)行腎臟移植。目前，多數(shù)研究人員都認(rèn)為同時(shí)移植兩個(gè)器官對(duì)病人自身系統(tǒng)影響太大，而且極大地增加了整體的風(fēng)險(xiǎn)。

　　Section II Reading Comprehension Part A

　　Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points)

　　How can the train operators possibly justify yet another increase to rail passenger fares? It has become a grimly reliable annual ritual: every January the cost of travelling by train rises, imposing a significant extra burden on those who have no option but to use the rail network to get to work or otherwise. This years rise, an average of 2.7 per cent, may be a fraction lower than last years, but it is still well above the official Consumer Price Index (CPI) measure of inflation.

　　Successive governments have pertted such increases on the grounds that the cost of investing in and running the rail network should be borne by those who use it, rather than the general taxpayer. Why, the argument goes, should a car-driving pensioner from Lincolnshire have to subsidise the daily commute of a stockbroker from Surrey? Equally there is a sense that the travails of commuters in the South East, many of whom will face among the biggest rises, have received too much attention compared to those who must endure the relatively poor infrastructure of the Midlands and the North.

　　However, over the past12 months, those commuters have also experienced some of the worst rail strikes in years. It is all very well train operators trumpeting the improvements they are making to the network, but passengers should be able to expect a basic level of service for the substantial sums they are now paying to travel. The responsibility for the latest wave of strikes rests on the unions. However, there is a strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.

　　The Government has pledged to change the law to introduce a minimum service requirement so that, even when strikes occur, services can continue to operate. This should form part of a wider package of measures to address the long-running problems on Britains railways. Yes, more investment is needed, but passengers will not be willing to pay more indefinitely if they must also endure cramped, unreliable services, punctuated by regular chaos when timetables are changed, or planned maintenance is managed incompetently. The threat of nationalisation may have been seen off for now, but it will return with a vengeance if the justified anger of passengers is not addressed in short order.

　　考研英語(yǔ)閱讀理解專(zhuān)項(xiàng)試題及答案 5

　　Last year marked the third year in a row of that Indonesia’s bleak rate of deforestation has slowed in pace. One reason for the turnaround may be the countrys antipoverty program.

　　In 2007, Indonesia started phasing in program that gives money to its poorest residents under certain conditions, such as requiring people to keep kids in school or get regular medical care. Called conditional cash transfers or CCTs, these social assistance programs are designed to reduce inequality and break the cycle of poverty. Theyre already used in dozens of countries worldwide. In Indonesia, the program has provided enough food and medicine to substantially reduce severe growth problems among children.

　　But CCT programs dont generally consider effects on the environment. In fact, poverty alleviation and environmental protection are often viewed as conflicting goals, says Paul Ferraro, an economist at Johns Hopkins University.

　　Thats because economic growth can be correlated with environmental degradation, while protecting the environment is sometimes correlated with greater poverty. However, those correlations dont prove cause and effect. The only previous study analyzing causality, based on an area in Mexico that had instituted CCTs, supported the traditional view. There, as people got more money, some of them may have more cleared land for cattle to raise for meat, Ferraro says.

　　Such programs do not have to negatively affect the environment, though. Ferraro wanted to see if Indonesias poverty-alleviation program was affecting deforestation. Indonesia has the third-largest area of tropical forest in the world and one of the highest deforestation rates.

　　Ferraro analyzed satellite data showing annual forest loss from 2008 to 2012-including during Indonesias phase-in of the antipoverty program-in 7, 468 forested villages across 15 provinces and multiple islands. The duo separated the effects of the CCT program on forest loss from other factors, like weather and macroeconomic changes, which were also affecting forest loss. With that, "we see that the program is associated with a 30 percent reduction in deforestation," Ferraro says.

　　Thats likely because the rural poor are using the money as makeshift insurance policies against inclement weather, Ferraro says. Typically, if rains are delayed, people may clear land to plant more rice to supplement their harvests. With the CCTs, individuals instead can use the money to supplement their harvests.

　　Whether this research translates elsewhere is anybodys guess. Ferraro suggests the importance of growing rice and market access. And regardless of transferability, the study shows that whats good for people may also be good for the value of the avoided deforestation just for carbon dioxide emissions alone is more than the program costs.

　　【選項(xiàng)】
