本文中,朗阁老师将结合剑桥雅思真题集中的例子,重点分析其中一类---实验类。

就笔者对雅思真题剑桥四到十二的研读和分析,就难道而言粗略的将这些书本的分成三种类别。一类包含剑四到剑六,这些书当中的习题相对比较简单,包含教多简单题型(判断题,总结题,解答题)且相对定位比较容易,定位词效用比较明显。第二类包含剑七和剑八,这两本书相对较难,主要表现在有很多的heading题和配对题。

 

第三类是较近几年出的剑九到剑十二,较大的特征是做题不再是简单的定位回到原本找答案这么机械简单,因为很多都出现了定位词失效的情况(单词替换),这样的情况对词汇基础的薄弱的考生是一个非常大的考验。而且就近几年考试题型总结,配对题是必考题,也是考生拿到阅读*的拦路虎,这个题型原本的特点就是没有清晰的定位词。要做对题好像只剩下通读全文,耗时费力。

       

就上述情况的分析,笔者认为,分析文章的结构帮助确定题目在文章中的相对位置是较科学的应对方式。分析文章结构,其本质也就是在梳理文章时筛选出重要信息,并且根据文章发展的逻辑和脉络,细读文章重要信息,忽略无用的内容,对信息进行甄别和取舍。如果在做题前就能对文章的思路了如指掌,那就好比站在作者的高度,做题定位时也就能够有的放矢了。

        

虽然雅思阅读的文章题材多样,考察的单词量也比较大,不易看懂,但是雅思阅读文章多是*性的本质,决定了该类型的文章结构也相对比较固定。雅思阅读文章一般可以分为两大类:介绍类的说明文和论证类的*论文。前者主要是针对一个既定的客观事实进行陈述,不包含argument;后者则是针对一个悬而未决的问题进行分析论证,继而提出解决方案,其过程一般为提出问题,分析问题,解决问题。而在具体情况下,这类*类的文章又可以分为两类:实验类和逻辑辩论类。下面,笔者就将结合剑桥雅思真题集中的例子,重点分析其中一类---实验类。

         

 

剑五test1passage2 nature or nurture

 

A段:    

 

A few years ago, in one of the most fascinating and disturbing experiments in behavioral psychology, Stanley Milgram of Yale University tested 40 subjects from all walks of life for their willingness to obey instructions given by a 'leader' in a situation in which the subjects might feel a personal distaste for the actions they were called upon to perform. Specifically, Milgram told each volunteer 'teacher-subject' that the experiment was in the noble cause of education, and was designed to test whether or not punishing pupils for their mistakes would have a positive effect on the pupils' ability to learn.

 

B段:

 

Milgram's experimental set-up involved placing the teacher-subject before a panel of thirty switches with labels ranging from '15 volts of electricity (slight shock)' to '450 volts (danger - severe shock)' in steps of 15 volts each. The teacher-subject was told that whenever the pupil gave the wrong answer to a question, a shock was to be administered, beginning at the lowest level and increasing in severity with each successive wrong answer. The supposed 'pupil' was in reality an actor hired by Milgram to simulate receiving the shocks by emitting a spectrum of groans, screams and writings together with an assortment of statements and expletives denouncing both the experiment and the experimenter. Milgram told the teacher-subject to ignore the reactions of the pupil, and to administer whatever level of shock was called for, as per the rule governing the experimental situation of the moment.

 

C段:

 

As the experiment unfolded, the pupil would deliberately give the wrong answers to questions posed by the teacher, thereby bringing on various electrical punishments, even up to the danger level of 300 volts and beyond. Many of the teacher-subjects balked at administering the higher levels of punishment, and turned to Milgram with questioning looks and/or complaints about continuing the experiment. In these situations, Milgram calmly explained that the teacher-subject was to ignore the pupil's cries for mercy and carry on with the experiment. If the subject was still reluctant to proceed, Milgram said that it was important for the sake of the experiment that the procedure be followed through to the end. His final argument was, 'You have no other choice. You must go on.' What Milgram was trying to discover was the number of teacher-subjects who would be willing to administer the highest levels of shock, even in the face of strong personal and moral revulsion against the rules and conditions of the experiment.

 

D段:          

 

Prior to carrying out the experiment, Milgram explained his idea to a group of 39 psychiatrists and asked them to predict the average percentage of people in an ordinary population who would be willing to administer the highest shock level of 450 volts. The overwhelming consensus was that virtually all the teacher-subjects would refuse to obey the experimenter. They psychiatrists felt that 'most subjects would not go beyond 150 volts' and they further anticipated that only four per cent would go up to 300 volts. Furthermore, they thought that only a lunatic fringe of about one in 1,000 would give the highest shock of 450 volts.

 

E段:

 

What were the actual results? Well, over 60 per cent of the teacher-subjects continued to obey Milgram up to the 450-volt limit! In repetitions of the experiment in other countries, the percentage of obedient teacher-subjects was even higher, reaching 85 per cent in one country. How can we possible account for this vast discrepancy between what calm, rational, knowledgeable people predict in the comfort of their study and what pressured, flustered, but cooperative 'teachers' actually do in the laboratory of real life?

 

F段:

One's first inclination might be to argue that there must be some sort of built-in animal aggression instinct that was activated by the experimental, and the Milgram's teacher-subjects were just following a genetic need to discharge this pent-up primal urge onto the pupil by administering the electrical shock. A modern hard-core social-biologist might even go so far as to claim that this aggressive instinct evolved as an advantageous trait, having been of survival value to our ancestors in their struggle against the hardships of life on the plains and in the caves, ultimately finding its way into our genetic make-up as a remnant of our ancient animal ways.

 

G段:          

An alternative to this notion of genetic programming is to see the teacher-subjects' actions as a result of the social environment under which the experiment was carried out. As Milgram himself pointed out, 'Most subjects in the experiment see their behavior in a larger context that is benevolent and useful to society - the pursuit of scientific truth. The psychological laboratory has a strong claim to legitimacy and evokes trust and confidence in those who perform. there. An action such as shocking a victim, which in isolation appears evil, acquires a completely different meaning when placed in this setting'.

 

H段:

Thus, in this explanation the subject merges his unique personality and personal and moral code with that of larger institutional structures, surrendering individual properties like loyalty, self-sacrifice and discipline to the service of malevolent systems of authority.

 

I段:        

Here we have two radically different explanations for why so many teacher-subjects were willing to forgot their sense of personal responsibility for the sake of an institutional authority figure. The problem for biologists, psychologists and anthropologists is to sort out which of these two polar explanations is more plausible. This, in essence, is the problem of modern sociobiology - to discover the degree to which hard-wired genetic programming dictates, or at least strongly biases, the interaction of animals and humans with their environment, that is, their behavior. Put another way, sociobiology is concerned with elucidating the biological basis of all behavior.

       

不知道考生在想到实验类的文章会想到什么,笔者回想起学校物理课写的实验报告。该报告的组成是实验目的,实验过程,实验结果。回到该文章,我们通过每段话的首句分析,可以看清楚文章的发展逻辑。

        

首段主要讲的是Stanley Milgram做实验的目的。tested 40 subjects from all walks of life for their willingness to obey instructions given by a 'leader' in a situation in which the subjects might feel a personal distaste for the actions they were called upon to perform,测试实验主题对*者的要求的配合度。也就是笔者在前文提到的实验目的。(可以做选择题的*题以及判断题的*题)

 

精读 第二段首句Milgram's experimental set-up involved placing the teacher-subject before a panel of thirty switches with labels ranging from '15 volts of electricity (slight shock)' to '450 volts (danger - severe shock)' in steps of 15 volts each. 我们可以发现实验的安排是电击等级从十五到四百五十伏。(选择题的第二题出自这个段落)

 

第三段的首句内容是指的实验过程中的情况,因为首句有描述as the experiment unfolded.

 

第四段的首句涉及题库结果,Prior to carrying out the experiment, Milgram explained his idea to a group of 39 psychiatrists and asked them to predict the average percentage of people in an ordinary population who would be willing to administer the highest shock level of 450 volts. 题库的是会按电击到四百五十伏的人数。(可以做选择题的较后一题)

 

按照逻辑来看,接下来我们应该可以题库的内容是实验真正的结果。精读第五段的首句我们不难发现,内容确实是这个。what are the actual results?

 

那么按照文章发展的逻辑来看,接下来的内容应该是考虑出现实验结论的原因,One's first inclination might be to argue that there must be some sort of built-in animal aggression instinct that was activated by the experimental, and the Milgram's teacher-subjects were just following a genetic need to discharge this pent-up primal urge onto the pupil by administering the electrical shock.An alternative to this notion of genetic programming is to see the teacher-subjects' actions as a result of the social environment under which the experiment was carried out.一是基因请款导致,二十实验者认为自己是在追寻科学真理。

 

较后是文章的总结,引入social biology的问题。

 

总结来看,文章的脉络如下:

 

实验前 包括1. Introduction ( 即点出实验目的—— The aim of this experiment , 或 The explanation for the experiment )。实验前除了对实验目的做出解释外,还有就是2. Background (即对和开展该实验有关的所有东西的介绍,例如实验器材,实验人员,知识背景,身份,实验的架构,历经时间等等)

 

实验中 就是实验的开始阶段 Findings 的过程,包括实验的 具体操作过程 和实验中 发现的事实或情况 。

 

实验后 包括 实验较终结果 ,或者较终结果阐述前插入一段 实验的题库结果 ,当然较终结果的后面还有可能插入对 实验结果的原因分析 。

 

文章的 较后一段 就是 对整个实验的 再次总结 以及对今后某个领域 提出新的课题 。

 

在理清楚文章脉络之后,这篇文章当中较难的段落细节匹配题,也就是笔者在前文讲过的这个阅读*拦路虎也就没有那么难了。

 

14   a biological explanation of the teacher-subjects’ behavior

15   the explanation Milgram gave the teacher -subjects for the experiment

16   the identity of the pupils

17   the expected statistical outcome

18   the general aim of sociobiological study

19   the way Milgram persuaded the teacher-subjects to continue

 

按照分类不难看出,14应该隶属于试验后的行为解释,所以答案应该是在F段或者G段,再来看到是生物学的解释,所以答案只能是F了;15题是M对于实验的解释也就是实验目的,所以答案应该是A段;16题主要问到的是小宝贝的身份,属于实验准备,也就是B段;17是题库实验结果,可以通过D段的首句确认答案;18涉及了social biological的内容,那么答案不难确定应该是I段;较后19题是M劝服学生继续实验,该归属于实验过程,也就是C段。

       

以上分析,笔者认为,确认文章类型,分析文章发展脉络,对段落细节匹配题,甚至是应对笔者前文提到的剑九到剑十二的既定出题发展方向---定位难,定位词失效,这都是一个非常好的方式。不仅可以加快阅读速度,也可以进步做题的准确率。望考生可以在平时的阅读当中,养成分析文章脉络,细读每段首句主题句的习惯。
