Do you know that all human beings have a "comfortable zone" regulating the distance they s

Greeks, others of the Eastern Mediterranean, and many of those from South America normally stand close together when they talk, often moving their faces even closer as they warm up in a conversation. North Americans find this awkward and often back away a few inches. Studies have found that they tend to feel most comfortable at about 21 inches apart. In much of Asia and Africa, there is even more space between two speakers in conversation. This greater space subtly lends an air of dignity and respect. This matter of space is nearly always unconscious, but it is interesting to observe.

This difference applies also to the closeness with which people sit together, the extent which they lean over one another in conversation, how they move as they argue, or make an emphatic point. In the United States, for example, people try to keep their bodies apart even in a crowded elevator; in Paris they take it as it comes!

Although North Americans have a relatively wide "comfortable zone" for talking, they communicate, a great deal with their hands—not only with gestures but also with touch. They put a sympathetic hand on a person's shoulder to demonstrate warmth of feeling or an arm around him in sympathy; they nudge a man in the ribs to emphasize a funny story; they pat an arm in reassurance or stroke a child's head in affection, they readily take someone's arm to help him across a street or direct him along an unfamiliar route. To many people—especially those from Asia or the Moslem countries—such bodily contact is unwelcome, especially if inadvertently done with the left hand. (The left hand carries no special significance in the U.S. Many Americans are simply left handed and use that hand more. )

In terms of bodily distance, North Americans ______.

A．are similar to South Americans

B．stand farthest apart

C．feel ill at ease when too close

D．move nearer during conversations
