Spacing in Animals
1. Any observant person has noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it flees.“Flight distance”is the terms used for this interspecies spacing. As a general rule,there is a positive relationship between the size of an ani-mal and its flight distance-the larger the animal,the greater the distance it must keep between itself and the enemy.An antelope will flee when the enemy is as much as five hundred yards a-way .The wall lizard's flight distance,on the other hand,is about six feet. Flight is the basic means of survival for mobile creatures.
2. Critical distance apparently is present wherever and whenever there is a flight reaction.“Criti-cal 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 the lion's critical distance,at which point the cor-nered lion reverses direction and begins slowly to stalk the man.
3 .Social animals need to stay in touch with each other. Loss of contact with the group can be fatal for a variety of reasons including exposure to enemies.Social distance is not simply the dis- tance 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 he exceeds its limits.We can think of it as a hidden band that contains the group.
4. Social distance varies from species to species.It is quite short-apparently only a few yardsamong some animals,and quite long among others.
5. Social distance is not always rigidly 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 the baboons 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 shrinks.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.

Social distance______.
A: differs among animal species
B: to psychological distance
C: begin to attack
D: to physiological distance
E: distance between an animal and its enemy before fleeing
F: distance between certain animal species before fleeing

    第一篇

    In the dark night of the desert,a group of U.S.Air Force scientists is testing a new device for a missile to target.Designed to seek out the heat of an enemy aircraft engine,it is now going through its paces by tracing the movement of a flashlight waving thirty feet away in the darkness.A hundred yards away,unseen by the man,a rattlesnake sliding between the stones senses a patch of warmth. Although the snake's mechanism is small enough to be packed into a head the size of a nut,it can detect a change in temperature of one-thousandth of a degree.With a sound the snake closes in and strikes for the kill.
    Whenever we look in the animal world we find the same story.Almost anything that man can do,nature has already done better. So,it is for the purpose of learning from nature that a new science called bionics has grown up.Its aim is to find out how animal's instruments work so that man can copy them for his own purpose.
    Imagine being able to know a friend several miles off by his smell. Male silk moths can do this. Their antennae are so sensitive to the chemical odor of female moths that they can detect their presence by picking up only one molecule of the chemical.Even with their most sensitive instruments, human cannot approach this perfection.
    Studying beetle's eyes has already paid off. A group of scientists in Germany found that a beetle can accurately measure with its eyes the speed of moving background.After finding out how a beetle accomplishes this scientists built a machine that operated on the same principle.This instrument is able to determine the ground speed of moving aircraft with a high degree of accuracy.

    The goal for bionics is to______.
    A:explain how animal devices work
    B:copy animal processes with man-made machines
    C:prove the usefulness of this science
    D:apply science to the study of animals

    Spacing in Animals
    1. Any observant person has noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it flees.“Flight distance”is the terms used for this interspecies spacing. As a general rule,there is a positive relationship between the size of an ani-mal and its flight distance-the larger the animal,the greater the distance it must keep between itself and the enemy.An antelope will flee when the enemy is as much as five hundred yards a-way .The wall lizard's flight distance,on the other hand,is about six feet. Flight is the basic means of survival for mobile creatures.
    2. Critical distance apparently is present wherever and whenever there is a flight reaction.“Criti-cal 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 the lion's critical distance,at which point the cor-nered lion reverses direction and begins slowly to stalk the man.
    3 .Social animals need to stay in touch with each other. Loss of contact with the group can be fatal for a variety of reasons including exposure to enemies.Social distance is not simply the dis- tance 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 he exceeds its limits.We can think of it as a hidden band that contains the group.
    4. Social distance varies from species to species.It is quite short-apparently only a few yardsamong some animals,and quite long among others.
    5. Social distance is not always rigidly 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 the baboons 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 shrinks.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.

    “‘Flight distance' is the terms used for this interspecies spacing.”“逃离距离”是用来描述物种间的这种间隔距离的术语。


    这一段一开头就提到，危险距离指的是逃离距离和进攻距离之间的狭窄区域。


    这段讲的就是动物间的社会距离的概念及其重要性。


    这一段第一句话就提到“社会距离不是不变的，而是部分取决于环境的。”


    答案可以从第一段找到，最符合原文对flight distance下的定义。


    “…at which point the cornered lion reverses direction and begins slowly to stalk the man.”这时走投无路的狮子调转过头来，开始慢慢地前进，接近人。所以当动物危险距离被入侵时，动物开始攻击。


    根据文章，社会距离指心理距离。原句：…it is rather a psychological distance.


    动物间的社会距离不同。文中原句为：Social distance varies from species to species.

    Spacing in Animals
    1. Any observant person has noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it flees.“Flight distance”is the terms used for this interspecies spacing.As a general rule,there is a positive relationship between the size of an ani-mal and its flight distance-the larger the animal,the greater the distance it must keep between itself and the enemy.An antelope will flee when the enemy is as much as five hundred yards a-way .The wall lizard's flight distance,on the other hand,is about six feet. Flight is the basic means of survival for mobile creatures.
    2. Critical distance apparently is present wherever and whenever there is a flight reaction.“Criti-cal 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 the lion's critical distance,at which point the cornered lion reverses direction and begins slowly to stalk the man.
    3. Social animals need to stay in touch with each other. Loss of contact with the group can be fa-tal for a variety of reasons including exposure to enemies.Social distance is not simply the dis-tance 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 ani- mal apparently begins to feel anxious when he exceeds its limits.We can think of it as a hidden band that contains the group.
    4. Social distance varies from species to species. It is quite short-apparently only a few yards- among some animals,and quite long among others.
    5. Social distance is not always rigidly 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 dis-tance may be the length of her reach .This is readily observed among the baboons 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 shrinks.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.

    If an animal's critical distance is penetrated,it will______.
    A: differs among animal species
    B: to psychological distance
    C: begin to attack
    D: to physiological distance
    E: distance between an animal and its enemy before fleeing
    F: distance between certain animal species before fleeing

    答案：C
