Most people feel lonely sometimes, but it usually lasts only a few minutes or 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 kinds of loneliness．
The first kind of loneliness is temporary．This is the most mon type．It usually disappears quickly and does not need any special attention．
The second kind, situational loneliness, is a natural result of a certain situation, for example, a 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 severe．Unlike the second type, chronic （长期的） loneliness usually lasts more than two years and has no specific cause．People who experience habitual loneliness have problems socializing and being close to others．Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition．
Psychologists agree that one important factor in loneliness is a person's social contacts, such as friends, family members, co-workers, 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 interests and activities．However, psychologists have found that, though lonely people have many social contacts, they sometimes feel they should have more．They question then own popularity．
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 normal and healthy part of life, chronic loneliness can be a very sad and sometimes dangerous condition．

(答案→)B
解析：
【小题1】细节题。第三段谈到situational loneliness，其中有一个例子是moving to a new place，和changing work相一致。
【小题2】细节题。这一段谈论的就是situational loneliness，最后一句话中的such as headaches and sleeplessness只是指它带来的危害表现，it usually does not last for more than a year中的it很显然就是指这种孤独不会延续很长时间。
【小题3】细节推断题，从第二段It usually disappears quickly and does not need any special attention．可以判断我们不必要为这个问题着急。
【小题4】推理题。从第五段第一句话Psychologists agree that one important factor in loneliness is a person's social contacts, such as friends, family members,co-workers, etc．可以看出，人们感到孤独是在一定的情况下（与社会的联系）产生的。
