Aided by the recent ability to analyze

samples of air trapped in glaciers,

scientists now have a clearer idea of

the relationship between atmospheric

(5) composition and global temperature

change over the past 160,000 years. In

particular, determination of atmospheric

composition during periods of glacial

expansion and retreat (cooling and (10) warming) is possible using data from the

2,000 meter Vostok ice core drilled in

Antarctica. The technique involved is

similar to that used in analyzing cores

of marine sediments, where the ratio of (15) the two common isotopes of oxygen, 12O

and 16O, accurately reflects past

temperature changes. Isotopic analysis

of oxygen in the Vostok core suggests

mean global temperature fluctuations (20) of up to 10 degrees centigrade over the

past 160,000 years.

Data from the Vostok core also

indicate that the amount of carbon

dioxide has fluctuated with tempera- (25) ture over the same period: the higher

the temperature, the higher the

concentration of carbon dioxide and the

lower the temperature, the lower the

concentration. Although change in carbon (30) dioxide content closely follows change

in temperature during periods of deglaci

ation it apparently lags behind

temperature during periods of cooling.

The correlation of carbon dioxide with (35) temperature, of course, does not

establish whether changes in atmospheric

composition caused the warming and

cooling trends or were caused by their.

The correlation between carbon dioxide (40) and temperature throughout the Vostok

record is consistent and predictable.

The absolute temperature changes,

however, are from 5 to 14 times greater

than would be expected on the basis of (45) carbon dioxide's own ability to absorb

infrared radiation, or radiant heat.

This reaction suggests that, quite aside

from changes in heat-trapping gases,

commonly known as greenhouse gases, (50) certain positive feedbacks are also

amplifying the temperature change. Such

feedbacks might involve ice on land and

sea, clouds, or water vapor, which also

absorb radiant heat.

(55) Other data from the Vostok core show

that methane gas also correlates closely

with temperature and carbon dioxide.

The methane concentration nearly

doubled,for example, between the peak

(60) of the penultimate glacial period and

the following interglacial period. Within

the present interglacial period it has

more than doubled in just the past 300

years and is rising rapidly. Although

(65) the concentration of atmospheric methane

is more than two orders of magnitude

lower than that of carbon dioxide, it

cannot be ignored: the radiative

properties of methane make it 20 times

(70) more effective, molecule for molecule,

than carbon dioxide in absorbing radiant

heat. On the basis of a simulation model

that climatological researchers have

developed, methane appears to have

(75) been about 25 percent as important as

carbon dioxide in the warming that took

place during the most recent glacial

retreat 8,000 to 10,000 years ago.

The primary purpose of the passage is

to

interpret data

explain research methodology

evaluate a conclusion

suggest a new technique

attack a theory

答案:(A)

最近,科学家已能够对困在冰川中的空气样品进行分析。在这一能力的帮助下,科

学家现在对过去160,000年中大气构成与全球气温变化之间的关系有了一个更为清晰的了解。尤其是,通过利用在南极洲自2,000米深处东方站(Vostok)冰芯钻探挖掘得到

的数据,对冰川扩张和消退(降温和升温)期间的大气构成予以确定,已成为可能。这一过程所涉及的技术类似于分析海洋沉积物岩芯所应用的技术,在此研究中,氧气的两个普通同位素(12O和16O)的比率精确地折射出过去的温度变化。对东方站冰芯中的氧气进行的同位素分析表明,在过去的160,000年中,全球平均气温波动变化高达摄氏10

度。

来自东方站冰芯的数据还表明,在同一时期,二氧化碳的数量也随着温度而波动变

化:气温越高,二氧化碳含量越高;气温愈低,二氧化碳含量愈低。尽管在冰川消退期,二氧化碳含量的变化紧随着气温的变化,但在降温期,二氧化碳含量的变化显然滞后于气温。当然,二氧化碳与气温的关系无法确定大气构成的变化是否导致了升温和降温趋势,或者被它们所导致。

在东主站的整个记录中。二氧化碳与气温的关系是连贯一致的和可预测的。但是,

绝对温度变化比人们所期待的要超出4至15倍,而人们所依据的是二氧化碳自身吸收

红外辐射(infrared radiation)或辐射热(radiant heat)的能力。这种关系表明,

要相当程度上,除了捕热气体(即通常所称为的温室气体)以外,某些正反馈也会扩大温度变化。此类反馈可能涉及到陆地上和海洋中的冰、云、或水蒸气,它们也都会吸收辐射热。

来自东方站冰芯的其它数据表明,甲烷气体也与温度和二氧化碳密切相关。例

如,在倒数第二个冰川期高峰与随后的间冰期(interglacial)之间,甲烷的含量

几乎翻了一倍。在目前的间冰期范围内,它在过去短短的300年就已经增加了两倍

多,并正在迅速增长。尽管大气甲烷的含量要比二氧化碳的含量低两个数量级还不

至,但它仍不能被忽视:就分子与分子相对比,甲烷的辐射特性使其在吸收辐射热

这方面,要比二氧化碳强出20倍。从气候学研究者所建立的某个模拟模型来看,

在8,000至10,000年之前的最近一次冰川稍退期间发生的升温过程中,甲烷似乎

发挥了相等于二氧化碳25%的重要作用。

According to the passage, which of

the following statements about methane

is true?

Methane is found in marine sediments.

Methane is more effective than carbon

dioxide in absorbing radiant heat.

The Earth's atmosphere now contains

more than twice as much methane as it

does carbon dioxide.

The higher the concentration of carbon

dioxide in the Earth's atmosphere; the

lower the concentration of methane.

Most of the global warming that has

occurred during the past 10 years has

been associated with increased methane

concentration.

答案:(D)

最近,科学家已能够对困在冰川中的空气样品进行分析。在这一能力的帮助下,科

学家现在对过去160,000年中大气构成与全球气温变化之间的关系有了一个更为清晰的

了解。尤其是,通过利用在南极洲自2,000米深处东方站(Vostok)冰芯钻探挖掘得到

的数据,对冰川扩张和消退(降温和升温)期间的大气构成予以确定,已成为可能。这一过程所涉及的技术类似于分析海洋沉积物岩芯所应用的技术,在此研究中,氧气的两个普通同位素(12O和16O)的比率精确地折射出过去的温度变化。对东方站冰芯中的氧气进行的同位素分析表明,在过去的160,000年中,全球平均气温波动变化高达摄氏10 度。

来自东方站冰芯的数据还表明,在同一时期,二氧化碳的数量也随着温度而波动变

化:气温越高,二氧化碳含量越高;气温愈低,二氧化碳含量愈低。尽管在冰川消退期,二氧化碳含量的变化紧随着气温的变化,但在降温期,二氧化碳含量的变化显然滞后于气温。当然,二氧化碳与气温的关系无法确定大气构成的变化是否导致了升温和降温趋势,或者被它们所导致。

在东主站的整个记录中。二氧化碳与气温的关系是连贯一致的和可预测的。但是,

绝对温度变化比人们所期待的要超出4至15倍,而人们所依据的是二氧化碳自身吸收

红外辐射(infrared radiation)或辐射热(radiant heat)的能力。这种关系表明,

要相当程度上,除了捕热气体(即通常所称为的温室气体)以外,某些正反馈也会扩大温度变化。此类反馈可能涉及到陆地上和海洋中的冰、云、或水蒸气,它们也都会吸收辐射热。

来自东方站冰芯的其它数据表明,甲烷气体也与温度和二氧化碳密切相关。例

如,在倒数第二个冰川期高峰与随后的间冰期(interglacial)之间,甲烷的含量

几乎翻了一倍。在目前的间冰期范围内,它在过去短短的300年就已经增加了两倍

多,并正在迅速增长。尽管大气甲烷的含量要比二氧化碳的含量低两个数量级还不

至,但它仍不能被忽视:就分子与分子相对比,甲烷的辐射特性使其在吸收辐射热

这方面,要比二氧化碳强出20倍。从气候学研究者所建立的某个模拟模型来看,

在8,000至10,000年之前的最近一次冰川稍退期间发生的升温过程中,甲烷似乎

发挥了相等于二氧化碳25%的重要作用。

In The Women of Mexico City,1796-1857,

Sylvia Marina Arrom argues that the

status on women in Mexico City improved

during the nineteenth century.According

(5) to Arrom, households headed by females

and instances of women working outside

the home were much more common than

scholars have estimated; efforts by

the Mexican government to encourage

(10) female education resulted in increased

female literacy; and influential male

writers wrote pieces advocating

education, employment, and increased

family responsibilities for women, while

(15) deploring women's political and marital

inequality. Mention of the fact that the

civil codes of 1870 and 1884

significantly advanced women's rights

would have further strengthened Arrom's

(20) argument.

Arrom does not discuss whether

women's improved status counteracted

the effects on women of instability in the

Mexican economy during the nineteenth

(25) century.However, this is not so much a

weakness in her work as it is the inevi-

table result of scholars' neglect of this

period. Indeed, such gaps in Mexican

history are precisely what make Arrom's

(30) pioneering study an important addition

to Latin American women's history.

The passage is primarily concerned with

doing which of the following?

Reviewing a historical study of the

status of women in Mexico City during

the nineteenth century.

Analyzing the effects of economic

instability on the status of women in

Mexico during the nineteenth century

Advancing a thesis explaining why

women's status in Mexico City improved

during the nineteenth century

Rejecting the thesis that the status

of women in Mexico City during the nine-

teenth century actually improved

Praising an author for a pioneering

attempt to bridge significant gaps in

Mexico's economic history prior to 1790

答案:(A)

在《1796—1857年墨西哥城的妇女》(The Women of Mexico City,1796—1857)

一书中,西尔维亚·玛丽娜·艾隆(Sylvia Marina Arrom)论辩道,墨西哥城的

妇女在十九世纪地位得到了提高。按照艾隆的观点,以女性为主宰的家庭,以及妇女在家庭以外工作的景象,要比学者们所估计的程度来得普遍常见得多:墨西哥政府所作出的鼓励妇女教育的努力导致了妇女文化知识的提高,而有影响的男性作家

也撰文倡导为妇女提供教育、就职机会、以及更多的家庭责任,而在同时对妇女的政治和婚姻不平等则深表痛惜。如果提及这样一个事实,即1870年和1884年的民法(civil codes)大大提高了妇女的权益,则更有可能进一步加强艾隆的论点。

但艾隆没能探讨这样一个问题,即妇女地位的提高是否抵消了十九世纪墨西哥

经济不稳定对妇女产生的影响。然而,这与其说是她研究中的一个缺陷,倒不如说是学者们对这段历史漠然无视所导致的一个不可避免的结果。毫无疑问,正是墨西哥历史中的这些空白才使得艾隆的开拓性研究成为拉丁美洲妇女史的一种重要增补。

According to the author of the passage,

Arrom's study can be characterized as

"an important addition to Latin American

women's history" (lines 30-31) because it

offers a radical thesis concerning

the status of women's civil rights in

Mexican society during the nineteenth

century

relies on a new method of historical

analysis that has not previously been

applied to Latin American history

focuses only on the status of women

in Mexican society

addresses a period in Mexican history

that scholars have to some extent neglected

is the first study to recognize the

role of the Mexican government in

encouraging women's education

It can be inferred from the passage

that Arrom would agree with which of the

following assertions?

Efforts by the Mexican government

to encourage education for women during

the nineteenth century were hampered by

the economic instability of that period.

The most significant advances in the

rights of Mexican women during the nine-

teenth century occurred prior to 1857.

Improvements in the status of women

in Mexico City during the nineteenth

century were accompanied by similar

improvements in the status of women

in other large Latin American cities.

Scholars have in the past accorded

the most significance to nineteenth-

century Mexican literature that supported

the status quo in women's political and

marital rights.

Scholars have in the past under-

estimated the number of households

headed by females in Mexico City.

详解GRE阅读最常见三种题型

详解GRE阅读最常见三种题型 阅读题不管是放在哪一类考试上都能够算得上是一枚重磅炸弹。但是GRE阅读题因为是针对阅读英文能力的一种考察,那么对于中国考生而言也并非是容易的。以下GRE考试培训机构老师就要为考生们介绍GRE阅读最常见三种题型。 1. 主题题:一般在第一题,也会在中间2,3题,通常在末题出现的几率很少,解题技巧一般是从中心词(论述对象),配合TS(往往在首段出现,一定要记住“从前不从后”,原来的主旨为准),有时还要将下面的细节段落的层次关系概括考虑入内,得出答案。GRE考试培训机构老师表示若考生们在突破时可以边读边想,那么这个题不用15秒就可以看出,而后再使用原来积累的错误项的标志来“审核”(一定要注意永远别使用“排除法”来解这种题,否则浪费的时间是无法弥补的!),哪些标志呢?关键是记住细节段里的举例事物,唯一性,绝对性词汇就行了! 2. Insgroupsto题型:大家要注意到直接出现insgroupsto字样与也许会出现的“变体”,判断方式为该题问的是一种“因果联系”,还有作者提及A是为了什么,关于这个A能够是例子,又或是一个论证细节等等,那事不疑迟,马上从题干的事物出发返回到原文定位,而后快速的判断此层面的逻辑关系,而后决定是向上或者向下找几行,找到那个原因,提取“中心词”(有显着特征的词)而后在5个选项里识别出来,填上答案,不出30秒。 3. 作者态度题:回忆问及的事物是否给过“情态形容词或副词”修饰过,注意是“回忆”,针对此类词前面我已说过必须要注意留心,自己在突破里也许已经有所发现,大部分的书上还举出了动词,只要这种词一出现考生们都比较看得清,谁都知道是否定,但在此我举的就十分的隐蔽,独自的指出好像谁都知道,但在

In field practice, a subsurface is mapped by arranging a series of wave-train sources, such as small dynamite explosions, in a grid pattern. As each source is activated, it generates a wave train that moves downward at a speed determined uniquely by the rock’s elastic characteristics. As rock interfaces are crossed, the elastic characteristics encountered generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments. The seismic records must be processed to correct for positional differences between the source and the receiver, for unrelated wave trains, and for multiple reflections from the rock interfaces. Then the data acquired at each of the specific source locations are combined to generate a physical profile of the subsurface, which can eventually be used to select targets for drilling. 1.重点词汇 1. accuracy ['?kj?r?s?] n.

逻辑题讲解版1.0版 写在前面: 1.请同学们先在讲义上做题,带着问题来看这个讲解版。此为1.0版。适当时候我会加入新的题目的讲解,将其升级为 2.0 或者 3.0版本。不过这个目前应该是够用了。 2.以下的正确答案用黄色标示,错误选项的错误理由用“impose few rules and regulations”标示。 3.逻辑题中的错误选项大多都是跟本题没有任何关系的。逻辑题的错误选项的编撰者遇到的最大的 问题就是由于逻辑题的文章篇幅较短,无法使用文章中已有的部分来编制错误选项。于是,只能从文章之外寻找一些线索了。 4.此处的17题虽然不多,但是有一定的代表性。请各位在课外多做一些其它的GMAT的逻辑题强化此方面的能力和意识。 5.当然,各位应该知道GRE的Verbal部分的逻辑题数量较少。主要还是纯阅读部分的掌握,还记得我们上课经常说的那些东西吗?我想我上课中经常重复的东西可能还在你们耳边“阴魂不散”吧?“三强词汇”,“四大金刚”,“取非” “同义变换”。。。。。。。 归纳题: 例子1: T o be mentally healthy, people must have self-respect. People can maintain self-respect only by continually earning the respect of others they esteem. They can earn this respect only by treating these others morally. Which of the following conclusions can be properly drawn from the statements above? 解释:此题采用公共元素直推法。读完题目后我们知道正确答案肯定要跟mentally healthy 和treating these others morally 有关。 (A) People who are mentally healthy will be treated morally by others. (B) People who are mentally healthy will have treated morally those they esteem. (C) People who are mentally healthy must have self-respect in other to be treated morally by others. (D) People can expect to be treated morally by others only if they esteem these others. (E) People who have self-respect seldom treat morally those esteem. 其它的选项都跟这个没有关系 例子2: Experienced pilots often have more trouble than novice pilots in learning to fly the newly developed ultralight airplanes.

Clearly, Sparva’s less restrictive policy must be the explanation for the fact that altogether insurers there pay for far more treatments after accidents than insurers in other provinces, even though Sparva does not have the largest population. 1. Which of the following, if true, most strengthens the argument? A. Car insurance costs more in Sparva than in any other province. B. The cost of medical care in Sparva is higher than the national average. C. Different insurance companies have different standards for determining what constitutes emergency treatment. D.

Voltaire’s book commanded a wide audience, according to Feingold, because “he was neither a mathematician nor a physicist, but a literary giant aloof from the academic disputes over Newtonian ideas.” In other words, Voltaire’s amateurism in science “was a source of his

GRE阅读答题技巧

GRE阅读答题技巧 GRE阅读答题技巧 美国高校研究生院有很多都要求申请者提交GRE的分数。GRE考 试在数学、词汇和分析写作领域的本科学习中培养了抽象思维能力。这些考试不是针对任何特定的学术项目而设计的,而是根据过去学 生的成绩来预测一个学生在某一领域的成功。 考试总时长约为3小时45分。考试共分六部分,第三部分之后 有10分钟的休息。 六部分考试与时间分配: 分析性写作:包括两个单独计时的写作任务:逻辑立论文(AnalyzeanIssue)和驳论文(AnalyzeanArgument),各30分钟。 文字推理(VerbalReasoning):共两个部分,每部分约20题、30分钟。 数量推理(QuantitativeReasoning):共两个部分,每部分约20题、35分钟。 不计分题目(Unscored):题目数量不定,时间不定。 研究题目(Research):题目数量不定,时间不定。 不计分题目可能出现在写作之后的任意环节,考生在该部分的成绩将不被计入总分;研究题目经常出现在考试的最后,成绩也不被计 入总分。 文字推理部分也就是阅读时间紧任务重,是考试中一个不小的难题,那么: GRE的文章源于哪里?一篇GRE阅读的文章是怎样诞生的?

1.搜集“源文章” 出题机构一般有自己固定的信息源和搜集信息的渠道。如ETS使用一个名为SourceFinder的软件在Internet上自动检索数字论文 库EBSCO中的文献,并从中提炼出符合各种考试风格要求(比如GRE 和TOEFL等)的样本GRE阅读文章。 2.加工改写 出于版权限制,ETS用于实际的新GRE阅读考试的文章长度最多只能引用10%的原文长度。这种“带着镣铐跳舞”的`结果是大量文章内容被改写,重写和删节。改写一般会大量使用分词及从句,使 句子变得更紧凑、更严密。尽管改写后的文章会变得错综复杂,但 出题机构会尽量保持文章中原有的鲜明态度以及较好的层次结构。如:文章一开始给出一个老观点,后来有人提出新观点,驳斥老观点,文章作者对这个新观点或完全同意、或持部分保留意见、或是 做出有正有负的混合评价。 3.设置出题点 出题机构一般会先出关于文章主题、套路、态度、结构以及与文章的主题有关的问题,再针对文中比较明确的内容出题。在出题方 式上求新求变,一般会将原文中出现的词汇或句子换一种说法表达 出来。最后再找一些极易被考生忽略的细节作为出题对象,以此提 高考试难度,拉开考生的分数。 4.题材广泛,不拘一格 如前言中所说,GRE阅读理解的文章所涉及的题材有所区别,即GRE考试阅读没有管理类的文章,而这正是新GRE阅读经常出现的 题材。但总的来说,它们所涉及的题材都十分广泛。 一般来说,新GRE阅读文章可分为以下四类:人文类文章(humanities),自然科学类(science),社会科学类(socialscience)和商业管理类(business)。 从新GRE阅读文章选择可以看出,尽管GRE考试阅读文章涉及的学科众多,对这些杂乱的学科无需具备相应的知识,答案的重点均

GRE阅读解题规则技巧:注意文章措辞 对于GRE考试来说,学术化就是最大的纲,也是它迥异于托福雅思的纲。小站教育老师总结道,雅思托福的命题目的是生活化,而对于GRE来说,学术化代表着措辞的规范和温和。对于考生的意义在于,文章的整体是温和的,文章里面出现的极端的言辞都是要注意的,文章里面的事实都是与我们学术生活共时的,对于过去的追忆和反现实的虚拟状态,都是非常明显的潜在出题点。尤其是虚拟语气,往往表示应然而非然之状态,很有可能出现负评价,以态度题的方式考察。而一切过分极端的言辞,如绝对的说法,大多数,比较级尤其是强烈比较级,在文章里的出现要注意,还有一种也是强烈的对比的标志,就是以大写字母标注的时间,指明某时之前或之后,我们称之为时间强对比。以上总结之,即是三大关系,强对比,因果以及转折。表示这些关系的连词,一律要注意,最好做出标记。而对于题目来说,考生要注意以上说法是在哪里出现,如果文章有这些强烈的措辞,那么题目当中对应这些段落的选项也有,就很可能是对的,如果选项出现而文章的相应位置没有,则该选项必错。 GRE阅读解题规则技巧:预判作者态度 主题题,态度题如何解决呢?首先我们需要了解GRE的评价体系。对于激进的(进化论)左的(马列)上纲上线的,通常不与支持,对于以政治干涉学术,尤其反对。对于歧视弱者,损害弱者尤其反对,弱者恒强。 Should,must,should have 等词也是负评价,应然不然。选项中极端的,进行人生攻击的,模棱两可的,谄媚的,马上排除,因为这是学术考试。选项过分极端的副词,也要小心,如表示绝对的言辞。 GRE阅读解题规则技巧:正确处理文章 诸生读此类文章最大误区在于试图读懂,更有甚者,寻求文章之背景,遍寻译文,以期充分理解,虽有燃膏继晷之功,难有吴甲吞楚之效,盖此种文章,非为考生读懂而设计。更有甚者,仿阅读之结构,言辞,图作文之高分,则更加南辕北辙,缘木求鱼而已。请备考GRE考试的考生谨记: 这是考试,你只有13-15分钟做题,文章不是用来读懂的,对待难句最好的办法是考虑怎么不读,少读,而不是分析。 学术文章特点就是规范,层次清晰,主题明确。我们一定要读出套路,尤其是文章观点的数量,这个直接关系到主题题怎么出。我们要把每段的层次的连词标记出来,我们还要知道每个层次的主题词是什么,周围有没有否定词(改善题),有没有褒贬的词(态度题,应用题)。 至于例子,也可以考虑不读或者少读,因为GRE阅读重点考观点,例子是事实,事实记得越多,混淆信息越多,做题越慢,准确率越低。对于例子,只要记住位置就可以,题目考到再看,不考坚决不看。以观点记例子,以观点分层次,以观点分逻辑关系。 GRE阅读解题规则技巧:学会合理审题

The mouse will carry the food back to the nest, causing all of the mice to die, while a trap will kill only the one mouse that falls into it. If all signs of the mice disappear for three consecutive weeks after poisoned food is used, the homeowner can be sure that the poison was successful in eradicating the mice. Which of the following, if true, most seriously calls into question the exterminator’s claim that the absence of signs for three weeks means the mice have been eradicated by the poison? (A) Because mice hide whenever they sense humans, it is very difficult to see or hear mice even when there is an active infestation.

GRE长阅读习题

GRE长阅读习题 Mary Barton, particularly in its early chapters, is a moving response to the suffering of the industrial worker in the England of the 1840’s. What is most impressive about the book is the intense and painstaking effort made by the author, Elizabeth Gaskell, to convey the experience of everyday life in working-class homes. Her method is partly documentary in nature: the novel includes such features as a carefully annotated reproduction of dialect, the exact details of food prices in an account of a tea party (tea party: n.茶话会), an itemized description of the furniture of the Bartons’ living room, and atranscription (a recording (as on magnetic tape) made especially for use in radio broadcasting) (again annotated) of the ballad “The Oldham Weaver.” The interest of this record is considerable, even though the method has a slightly distancing effect. As a member of the middle class, Gaskell could

gre阅读真题的翻译和解析

gre阅读真题的翻译和解析 1.一种曾在19世纪造成白马铃薯饥荒的真菌的新的更有侵略性的类型在最近出现。然而由于这种真菌可以被加大用量的杀菌剂杀死,因而这种真菌不会带来对那些依赖于马铃薯为食物的国家造成大面积的食物短缺。 问题:下面哪一个会给文中的结论带来疑问? A.尽管马铃薯是世界上很多地方的主要农作物,在大多数国家人们首要的还是以小麦或者大米为食。 B.在新型真菌扩散的大多数国家农民不能增加他们在杀菌剂上的花费。 C.这种新的真菌是在被感染的马铃薯从一个马铃薯主要出口国出口过来之后开始传播的 D.在大多数国家马铃薯农除了使用杀死这种新型真菌的杀菌剂外还使用了几种杀虫剂 E.大多数政府留出了可以减轻类似于食物短缺和洪灾之类的大规模灾害的影响的资金。 答案选B,毋庸置疑。 2.作为机关,面临着预算困难,减少科学研究的支持,更大数量的类似研究是由私人基金会支持的。这种转变意味着会带来有争议的科学研究项目会在所有的支持的研究项目中占更少的部分,因为私人基金会考虑到自己的公共形象而趋向于避免争议。 问题:下面哪一个是上面的假设? A.只有那些不会有可能带来争议顾虑而进行的研究会产生科学上有效的结果。 B.支持科学研究项目的私人基金会意识到项目可能的争议是不可总避免的。 C.有私人基金会支持的项目科学家不同意支持机构在他们做研究时影响他们的做法。 D.许多的政府机构比私人基金会更在意自己的公共形象。 E.政府机构比私人机构更愿意支持会产生争议的科研项目。 答案选E,A无关,B相反,C也相反,D也是。 3.刑事审判陪审团不会依据任何目击者没有证实的证词做出裁决,这样很对,因为对任何人做出的未经证实的说法保持高度的怀疑是谨慎的。但是为做到始终如一,陪审团应该终止一种太寻常的行为:在未经证实的供认基础上对被告指控有罪。
