Most people feel lonely sometimes，but it usually only lasts between a few minutes and a few hours．（36）D In fact，it is quite normal．For some people，though，loneliness can last for years．Psychologists are studying this complex phenomenon，and have identified three different types of loneliness．
The first kind of loneliness is temporary．This is the most common type．It usually disappears quickly and does not require any special attention．The second kind，situation-for example，family problem，the death of a loved one，or moving to a new place．（37）C
The third kind of loneliness is the most severe．Unlike the others，chronic （the opposite of"temporary"）usually lasts more than two years and has no specific cause．（38）FUnfortunately，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，for example，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 similar interests and activities．However，psychologists have found that，though lonely people may have many social contacts，they sometimes feel they should have more．（39）G

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了大多数人都会感觉到孤独，其实孤独分为三种，不同的孤独有不同的症状．
解答 36．D 推理判断题．从后面一句的"In fact，it is quite normal．"可知这种情况不严重，很正常；故选D．
37．C 推理判断题．这是介于第一种和第三种的孤独症，时间应该介于temporary和more than two years之间，所以选择C．
38．F 推理判断题．从上下文Unfortunately，many chronically lonely people think there is little or nothing they can do to improve their condition可以判断此处应该是讲述第三种孤独症的症状．所以选择F．
39．G 推理判断题．从上文的"though lonely people may have many social contacts，they sometimes feel they should have more"可知他们没有安全感，不够自信．接下来就是质疑自己，选择G．
40．B 推理判断题．从最后一段的第一句Psychologists are trying to find ways to help habitually lonely people for two reasons可知本段讲述的是专家介入孤独症患者治疗的原因．从连词what's more也可以进一步确定答案是B．
点评 七选五阅读是完成性阅读，和完形填空很类似，不同的是一个选词，一个选句子．解题时，要注意上下文语境，充分考虑信息词（选项中和空格前后句子中相同或相近的词），选出最符合语境的句子．
