15.Walking down a path through some woods in Georgia,I saw a small pool of water ahead on the path.I changed my direction to go around it on the part of the path that wasn't covered by water or mud.As I reached the pool,I was suddenly attacked!Yet I did nothing for the attack.It was so unpredictable and from somewhere totally unexpected.I was surprised as well as unhurt though I had been struck four or five times.I backed up a foot and my attacker stopped attacking me.Had I been hurt,I wouldn't have found it amusing.And I was laughing.After all,I was being attacked by a butterfly!
Having stopped,laughing,I took a step forward.My attacker rushed me again.He charged towards me at full speed,attempting to hurt me but in vain.For a second time,I took a step backwards while my attacker paused.I wasn't sure what to do.After all,it's just not every day that one is attacked by a butterfly.I stepped back to look the situation over.My attacker moved back to land on the ground.That's when I discovered why my attacker was charging at me only moments earlier.He had a mate and she was dying.
Sitting close beside her,he opened and closed his wings as if to fan her.I could only admire the love and courage of that butterfly in his concern for his mate.He had taken it up on himself to attack me for his mate's sake,even though she was clearly dying and I was so large.He did so just to give her those extra few precious moments of life.His courage in attacking something thousands of times larger and heavier than himself just for his mate's safety seemed admirable.I couldn't do anything other than reward him by walking on the more difficult side of the pool.He had truly earned those moments to be with her,undisturbed.
Since then,I've always tried to remember the courage of that butterfly whenever I see huge barriers facing me.

科目:高中英语 来源: 题型:解答题

20.Proxemics (空间关系学) is the study of what governs how closely one person stands to another.People who feel close will be close,though the actual distances will vary between cultures.For Americans we can detect four main categories of distance:intimate (亲密的),personal,social and public.Intimate ranges from direct contact to about 45 centimeters.This is for the closest relationships such as those between husband and wife.Beyond this comes personal distance.This stands at between 45 and 80 centimeters.It is the most usual distance maintained for conversations between friends and relatives.Social distance covers people who work together or are meeting at social gatherings.Distances here tend to be kept between 1.30 to 2 meters.Beyond this comes public distance,such as that between a lecturer and his audience.
All cultures draw lines between what is an appropriate and what is an inappropriate social distance for different types of relationship.They differ,however,in where they draw these lines.Look at an international reception with representatives from the US and Arabic countries talking and you will see the Americans pirouetting (快速旋转) backwards around the hall pursued by their Arab partners.The Americans will be trying to keep the distance between themselves and their partners which they have grown used to regarding as"normal".They probably will not even notice themselves trying to adjust the distance between themselves and their partners,though they may have vague feeling that their Arab neighbors are being a bit"pushy".The Arab,on the other hand,coming from a culture where much closer distance is the pattern,may be feeling that the Americans are being"stand-offish".Finding themselves happier standing close to and even touching those they are in conversation with they will persistently pursue the Americans round the room trying to close the distance between them.
The appropriateness of physical contact varies between different cultures too.One study of the number of times people talking in coffee shops over a one-hour period showed the following interesting variations:London,0; Florida,2; Paris,10; and Puerto Rico 180.Not only does it vary between societies,however,it also varies between different subcultures within one society.Young people in Britain,for example,are more likely to touch and hug friends than are the older generation.This may be partly a matter of growing older,but it also reflects the fact that the older generation grew up at a time when touching was less common for all age groups.Forty years ago,for example,footballers would never hug and kiss one another on the field after a goal as they do today.
(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS)
78.What govern the standing space between two persons in proxemics?Relationships
79.The underlined word"stand-offish"in Paragraph 2 most probably means"cold/distant/keeping others at arm's length/not easily getting along".
80.Why may Arabs pursue Americans in a conversation at an international reception?
Because they try to close the distance between them
81.What can be inferred from the last paragraph is that the appropriateness of physical contact also varies withtime.
