Science seems to be getting closer to answering a very old mystery. Homing pigeons can be 　36　 hundreds of miles from their homes. When they are let to go to 　37　 again, they find their way home. Because of this special ability to 　38　,pigeons have been used 　 39　 messengers for hundreds of years.

Today people even breed homing pigeons for 　40　 at a sport. The birds are shipped to some chosen 　41　 a few hundred miles away. Then all of them are let to go together. The winner is the bird that gets home 　42　.A good race can make it home from 500 miles away 　43　 a single day.

The mystery of the homing pigeons is how they 　 44　 directions and how they find home. The first part seems to be pretty well 　 45　,and we know of two ways that pigeons tell directions. First, they use the sun. Experiments show that homing pigeons can tell 　46　 by the sun. What happens when the 　47　 is darkly overcoat by clouds and no one can 　48　 where the sun is? Then the pigeons still find their way home.

Naturally, people have wondered whether pigeons might have a built-in compass　 49　 that would tell them about the direction of the 　 50 　 magnetic(磁的)field. Many different kinds of experiments were 　 51 　.Here’s what the scientists decided 　 52　 they had made experiments many times. When pigeons can see the sun, they use it as their 　 53 　 means of direction-finding. When they can’t see the sun, they use some 　54　 way to sense direction from the earth’s magnetic field.

But how do pigeons know 　55　 direction is toward home? What do they use that we would call a map? These are other questions to be answered.

A

We like to keep our distance from others and there are very specific social rules about how close we can go to others in particular situations. The social distances here are approximate, of course and will vary with people. But they are still a good general rule. Hall identified four zones that are common for Americans:

Public Zone: >12 feet. The public zone is generally over 12 feet. That is, when we’re walking around town, we’ll try to keep at least 12 feet between us and other people. Of course there’re many times when we cannot do this. We’ll start to notice other people who are with in this distance. The closer they get, the more we become aware.

Social Zone:4-12 feet. Within the social zone, we start to feel a connection with other people. When they’re closer, then we can talk with them without having to shout, but still keep them at a safe distance. This is a comfortable distance for people who are standing in a group but maybe not talking directly with one another.

Personal Zone: 1.5-4feet. In the personal zone, the conversation gets more direct, and this is a good distance for two people who are talking seriously about something.

Intimate(亲密的)Zone: <1.5 feet. When a person is within arm’s reach or closer, then we can touch them in intimate ways. Romance of all kinds happens in this space. Entering intimate zone of somebody else can be very threatening.

The rules about social distances vary with different groups of people. People who live in towns spend more time close to one another. In a large and crowded city, the distances will be less than in a small town. Different countries also have different rules about social distances. Watch a Japanese person talking at a party with a person from a Western country. The Japanese will step in and the Westerner will step back. Speeded up, it’s like a dance around the room.
