　　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 the lion’s critical distance，at which point the cornered lion turns back and begins slowly stalk(逼近) the man.

　　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(刻板地) 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.

　　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.

　　2．If a lion’s critical distance is penetrated，it will

　　.

　　A．begin to attackB．try to hide

　　C．begin to jumpD．run away

　　3．The example of the children holding hands when crossing the street in the last paragraph shows that

　　.

　　A．social distance is not always needed

　　B．there is no social distance among children

　　C．human are different from animals in social distance

　　D．social distance is sometimes determined by outside factors(因素)

　　4．Which of the following can be the best title for the passage?

　　A．Critical DistanceB．Spacing in Animals

　　C．Relationship between AnimalsD．Psychological Distance
