     Most people feel lonely sometimes,but it usually only lasts between a few minutes and a few hours.

This kind of loneliness is not serious. In fact,it is quite normal. For some people,though, loneliness can last

for years. Now researchers say there are three different types of loneliness.

     The first kind of loneliness is temporary (暂时的). This is the most common type. It usually disappears quickly and does not require any special attention. The second kind is situation,for example,family problem,the death of a loved one,or moving to a new place. Although this kind of loneliness can cause physical

problems,such as headaches and sleeplessness, it usually does not last for more than a year.

The third kind of loneliness is the most serious. Unlike the second type,chronic (长期的) usually lasts

more than two years and has no specific cause. People who experience habitual loneliness have problems

socializing and becoming close to others. Unfortunately,many chronically lonely people think there is little

or nothing they can do to improve their condition.

     Psychologists (心理学家) agree that one important factor in loneliness is a person's social contacts,

for example,friends,family members,coworkers,etc. We depend on various people for different reasons.

For instance,our families give us emotional support,our parents and teachers give us guidance,and our

friends share similar interests and activities. However,psychologists have found that,though lonely people

may have many social contacts,they sometimes feel they should have more. They question their popularity (名气).

     Psychologists are trying to find ways to help habitually lonely people for two reasons:they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as

heart disease,while temporary and situational loneliness can be a sad,and sometimes dangerous condition.
