题文
Flight DistanceAny observant people have noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it escapes. “Flight distance” is the terms used for this interspecies spacing. As a general rule, there is a positive relationship between the size of an animal and its flight distance --- the larger the animal, the greater the distance it must keep between itself and the enemy. An antelope will escape when the enemy is as much as five hundred yards away. The wall lizard’s flight distance, on the other hand, is about six feet. Flight is the basic means of survival for mobile creatures.
Critical Distance
Critical distance apparently is present wherever and whenever there is a flight reaction. “Critical distance” includes the narrow zone separating flight distance from attack distance. A lion in a zoo will flee from an approaching man until it meets a barrier that it cannot overcome. If the man continues the approach, he soon penetrates（穿过，透过）the lion’s critical distance, at which point the cornered lion turns back and begins slowly stalk（逼近）the man.
Social Distance
Social animals need to stay in touch with each other. Loss of contact with the group can be fatal （致命的）for a variety of reasons including exposure to enemies. Social distance is not simply the distance at which an animal will lose contact with his group --- that is, the distance at which it can no longer see, hear, or smell the group --- it is rather a psychological distance, one at which the animal apparently begins to feel anxious when it goes beyond its limits. We can think of it as a hidden band that contains the group.
Social distance varies from species to species. It is quite short --- apparently only a few yards --- among some animals, and quite long among others.
Social distance is not always rigidly（刻板的）fixed but is determined in part by the situation. When the young of apes and humans are mobile but not yet under control of the mother’s voice, social distance may be the length of her reach. This is readily observed among baboons（狒狒）in a zoo. When the baby approaches a certain point, the mother reaches out to seize the end of its tail and pull it back to her. When added control is needed because of danger, social distance shortens. To show this in man, one has only to watch a family with a number of small children holding hands as they cross a busy street.
小题1:Which of the following is the most suitable explanation to “Flight distance”?A．Distance between animals of the same species before escaping.B．Distance between large and small animals before escaping.C．Distance between an animal and its enemy before escaping D．Distance between certain animal species before escaping.小题2:If a lion’s critical distance is penetrated, it will ________A．begin to attackB．try to hideC．begin to jumpD．run away小题3:The example of the children holding hands when crossing the street in the last paragraph shows that ________.A．social distance is not always neededB．there is no social distance among childrenC．humans are different from animals in social distanceD．social distance is sometimes determined by outside factors小题4:Which of the following one can be the best title of the passage?A．Critical DistanceB．Spacing in AnimalsC．Relationship Between AnimalsD．Psychological Distance 题型：未知 难度：其他题型
答案
小题1:C
小题1:A
小题1:D
小题1:B
解析
1.答案为c 根据第一段第一句“ ---a wild animal will allow a man or other potential enemy to approach only up to a given distance before it escapes.”可知答案。2.答案为A 根据第二段最后一句可知超过临界距离，狮子反而会进攻冒犯者。
3.答案为D 根据最后一段“Social distance is not always rigidly（刻板的）fixed but is determined in part by the situation.”可知答案。
4.答案为B 纵观全文主要在叙述“距离”，B选项起到了概括作用。
考点
据考高分专家说，试题“Flight DistanceAny o.....”主要考查你对 [政治经济类阅读 ]考点的理解。政治经济类阅读
政治经济类文章的概念：
要做好这类阅读，平时就要注意了解国内外发生的政治经济大事，掌握一定背景知识，对这类文章的叙述特点及内容安排有一定了解，还要扩展这方面的词汇。阅读这类文章，要抓住文章的核心，即文章整体和各段主要在说什么，也要注意段落之间的逻辑关系。
如何备考政治经济类阅读理解题：
【题型说明】政治经济类阅读文章是高考常选材料之一。该类文章时代气息浓郁，语言鲜活，但熟字新义词、超纲词及专业词语多，长句、难句多。政治类文章大多数是同学们感性趣的内容，读起来倒有似曾相识的感觉，经济类文章读起来就像是雾里看花，文章看完，一头雾水。再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨，同学们对这类题材是望而生畏。
【备考策略】建立心理优势。针对不同体裁的文章，我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式，我们可采取“顺读法”，以便抓关键语句，领会文章主旨；而经济类文章则多采用说明文形式，我们则可以采取“逆读法”，先读试题，再从文章中查找有用信息。若遇到的确难读的材料。千万不用着急，因为你觉得难，其他人也一定是同感。在高考前，我们就要有这种心理准备，高考试卷肯定有一、两篇难以阅读的材料。不过，我们平时可以有意识地从报刊杂志上找一些较难的阅读材料来阅读，以培养自己迎难而上的心理素质。
【答题方法】
1、寻找主干：
根据英语中五种基本句型结构，把句子中的主语、谓语、宾语、表语等主要成分找出来，其他成分如定语、状语、补语等则易于理解。找到了句子主干，句子的意思至少明白了一半。
2、剔除从句：
在一个长句中可能会出现若干个从句，在理解时，如果把各个从句剔除出来单独理解，然后把大意拼凑起来，整个长句的意思就会明白六、七分。
3、辨别分句：
一个长句如果是由几个并列、转折、递进、对比关系的分句组成，句中往往有表示这些分句关系的连接词，只要能弄清楚分句和分句之间的逻辑关系，再把各层分句的意思加以连贯，整个长句的句意基本上能跃然脑中。
4、寻找关键词：
如果一个句子看完，一点句意的感觉也没有，下下策就是抓住句中的关键词，通过关键词大体弄懂这个长句的意思。
