PASSAGE 33

Researchers in the field of psychology have found that one of the best ways to make an important decision, such as choosing a university to attend or a business to invest in, involves the utilization of a decision worksheet. Psychologists who study optimization compare the actual decisions made by people to theoretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision.

Since most important problems are multifaceted, there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question What will I do after graduation? A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year.

A decision-making worksheet begins with a succinct statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones. Focusing on long-range goals, a graduating student might revise the question above to What will I do after graduation that will lead to successful career?

托福阅读怎么抓住定位词

首先介绍一下，什么是定位词?

其实很简单，打个比方，你和朋友约好了去酒吧，朋友和你说酒吧在沈阳新东方正对面，这个酒吧你是不知道地点的，也就是你的目的地;而新东方却很熟知，那么你只需找到新东方便可以找到酒吧了。在这里新东方是已知的，就是用来定位的词汇，而酒吧则是你的目的所在，也便是你要找的答案。

定位词的称呼有很多，如关键词，主旨词，功能词，中心词等等。这些只是个名称罢了，含义都是一致的：一个可以根据题干回原文定位，并能够找到出处的词，这个题干中的词就是定位词 or key word。

定位词有什么样的特征?

定位词总体特征：不可变性和细节性

不可变性：定位词是用来定位的，所以必须找那些回原文依然不变的词汇，才有意义。通常不用动词和副词来定位。通常是名词或充当定语的形容词。

细节性：不要找大概念的词汇，更不要拿代表全文主旨的词汇来定位。换句话说不要找那些原文一大堆的词汇，无法定位。

如， 95年英国剑桥委员会British Council给出的唯一样题文章的题目是:The Spectacular Eruption of Mount St.Helens

下面有一道选择题是“ According to the text the eruption of Mount St.Helens and other volcanoes has influenced our climate by…”

拿这道题为例，如果大家把Mount St.Helens 作为关键词回原文进行定位，那你会郁闷致死，全文主要讲的就是圣海伦斯火山的喷发，原文有N多个Mount St.Helens，所以即使这个词属于大写的专有名词，但他违背了细节性，是概括性的词汇，也不能作为定位词来寻找答案。

究竟哪些词在阅读当中充当定位词?

以下是定位词的分类：

1.特殊词汇

在阅读中有一些词张的比较特殊，这种词很容易被记住，也很容易回原文定位。

好比，在大街上上看到一个人光着身子跑步-------特殊难看

一个人的个子超高，像姚明一样------特殊长

一个人身上穿着10多种颜色的衣服，而且不停的摇头-----特殊怪

特殊怪，特殊长，特殊难

这三种词就是特殊词的所有特征，在文中看到这样的词，一定要警惕。如，

Sequoia 美洲杉 ---特殊怪，很好定位，也经常作为考点。

sodium 【化学】钠---特殊难，大家只要知道是一种化学元素足矣。

Simultaneous 同时的---特殊长，这种词本身的特点决定应作为定位词。

2.数字：通常指时间，金钱和百分比。

有一个道题目是这样问的：

“What are the dates of the TWO major eruptions before 1980?”

那么像1980 3185$ 69%这些词因为长相原因，段落全是英文，突然跑出来几个数字，十分显眼，也就很好回原文找到他们。

3.专有名词：斜体字，大写人名,地名，大写的专有名词，这一点大家都很熟悉，不用多说。

4.特殊符号：

在特殊符号里或者旁边的词，最好通过符号回原文进行定位，如“paper conversation”，(three cubic miles) 这些词本身并没有什么特别，但放在符号里面，就可以根据符号回原文进行寻找。

总之，在国外考试的阅读中，无论是阅读文章，还是回答后面的10几道题目，定位词的寻找，都是一种有效的应试策略，更是学术文章的阅读的重要方法。

托福阅读不同题型的方法和技巧

一、单词题目

平时注意单词量的积累，力求达到可以随时随地记忆单词的境界。其实我们在记忆单词的时候也可以适当地使用一些策略，那就是在我们可以把自己的侧重点放在动词和形容词的记忆上。考试过后，你就会发现这个策略的事半功倍了。此外，对于自己不认识的单词，我们应该主动回原文找同义词，或找相关的提示信息。

二、找代词指代对象的题目

在考试中，它们主要会以如下两种形式出现。

(1)it、one、their、its、that类，这种题目主要是考查我们对于并列关系的掌握，这时，我们应该主动去看这个词所在的那整句话，从已知话中找到处于相同地位的词。

(2)考查由that、which涉及到的定语从句类，我们在面对这种题目时，应该有意识的在选项中找从句中谓语动词的发起者或接受者，因为只有这样才可以迈出通向胜利的第一步。

三、考查文章内容的题目

在历次的托福考试中，也存在着两大主要题型，即：文章细节考查题和文章结构考查题。

1、文章细节考查题

解答文章细节考查题，我们一般都可以回到原文中去做定位，找到相近或相似的内容，进而得出答案。

常见的定位有以下3种：

(1)题目本身给出定位。

(2)至少先可作出一个段落的定位。

(3)位置多夹于前后两题位置之间。

2、文章结构考查题

一定要注意：

(1)千万不要根据你读的信息去作推理。

(2)不要把文章从头到尾当成一个整体，尽可能各段独立。

(3)根据经验，在考试中，整篇文章的最后一句出题较多，所以应该仔细阅读这个重要的句子。

以上是针对托福考试阅读部分的常见题型做出的一些有关于考试解题方法与技巧的分项介绍。

在整个的阅读考试中，我们还应该了解到：

(1)在这个特殊的考试时间段内，我们的记忆比理解更为重要，在解题的时候一定要完全忠实于原文，切忌私自做出任何的主观臆断。

(2)在做题步骤方面，我们可以先简读原文(主要是各个段落的第一，二句话)，而后阅读题目，最后观察选项做出判断。值得我们特别注意的是，我们在做出判断的时候，切忌不要选择在选项中存在比较，而在原文中没有明确表示过的项目;切忌不要去选择那些说法过于绝对化的选项。

2.托福阅读TPO33(试题+答案+翻译)第:灭绝事件篇二

In 1977 ecologists Stephen Hubbell and Leslie Johnson recorded a dramatic example of how social interactions can produce and enforce regular spacing in a population. They studied competition and nest spacing in populations of stingless bees in tropical dry forests in Costa Rica. Though these bees do no sting, rival colonies of some species fight fiercely over potential nesting sites.

Stingless bees are abundant in tropical and subtropical environments, where they gather nectar and pollen from a wide variety of flowers. They generally nest in trees and live in colonies made up of hundreds to thousands of workers. Hubbell and Johnson observed that some species of stingless bees are highly aggressive to members of their species from other colonies, while other species are not. Aggressive species usually forage in groups and feed mainly on flowers that occur in high-density clumps. Nonaggressive species feed singly or in small groups and on more widely distributed flowers.

Hubbell and Johnson studied several species of stingless bees to determine whether there is a relationship between aggressiveness and patterns of colony distribution. They predicted that the colonies of aggressive species would show regular distributions, while those of nonaggressive species would show random or closely grouped (clumped) distribution. They concentrated their studies on a thirteen-hectare tract of tropical dry forest that contained numerous nests of nine species of stingless bees.

Though Hubbell and Johnson were interested in how bee behavior might affect colony distributions, they recognized that the availability of potential nest sites for colonies could also affect distributions. ?So as one of the first steps in their study, they mapped the distributions of trees suitable for nesting. ?They found that potential nest trees were distributed randomly through the study area. ?They also found that the number of potential nest sites was much greater than the number of bee colonies. ?What did these measurements show the researchers? The number of colonies in the study area was not limited by availability of suitable trees, and a clumped or regular distribution of colonies was not due to an underlying clumped or regular distribution of potential nest sites.

Hubbell and Johnson mapped the nests of five of the nine species of stingless bees accurately, and the nests of four of these species were distributed regularly. All four species with regular nest distributions were highly aggressive to bees from other colonies of their own species. The fifth species was not aggressive, and its nests were randomly distributed over the study area.

The researchers also studied the process by which the aggressive species establish new colonies. Their observations provide insights into the mechanisms that establish and maintain the regular nest distribution of these species. Aggressive species apparently mark prospective nest sites with pheromones, chemical substances secreted by some animals for communication with other members of their species. The pheromone secreted by these stingless bees attracts and aggregates members of their colony to the prospective nest site; however, it also attracts workers from other nests.

If workers from two different colonies arrive at the prospective nest at the same time, they may fight for possession. Fights may be escalated into protracted battles. The researchers observed battles over a nest tree that lasted for two weeks. Each dawn, fifteen to thirty workers from two competing colonies arrived at the contested nest site. The workers from the two colonies faced off in two swarms and displayed and fought with each other. In the displays, pairs of bees faced each other, slowly flew vertically to a height of about three meters, and then grappled each other to the ground. When the two bees hit the ground, they separated, faced off, and performed another aerial display. Bees did not appear to be injured in these fights, which were apparently ritualized. The two swarms abandoned the battle at about 8 or 9 A.M. each morning, only to re-form and begin again the next day just after dawn. While this contest over an unoccupied nest site produced no obvious mortality, fights over occupied nests sometimes kill over 1,000 bees in a single battle.
