There is an endless supply of stories about sleepwalkers(梦游者). People have been said to climb on roofs, solve mathematical problems, write music, walk through windows, and do murder in their sleep.
In Revere, Massachusetts, a hundred policemen searched for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there.
At the University of Lowa, a student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Lowa River. He would take a swim and then go back to his room to bed.
An American expert on sleep claims(声称) that he has never seen a sleepwalker. He is said to know more about sleep than any other living man, and during the last thirty-five years he has lost a lot of sleep watching people sleep. He says, “Of course, I know that there are sleepwalkers because I have read about them in the newspapers. But none of my sleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, I doubt whether I would get many takers(应征者).”
Sleepwalking, however, is a scientific reality. It is one of those strange things that sometimes look quite fantastic(奇特的). Doctors say that sleepwalking is much more common than is generally supposed. Many sleepwalkers do not try to find help and their sleepwalking is never recorded.

(答案→)A 解析：文章介绍了各种梦游的情况，那么梦游是真有其事还是虚构出来的？大多数梦游者不会因为他们的问题寻求帮助。所以还没有明确的解释。【小题1】细节题：从文章第一段的句子：People have been said to climb on roofs, solve mathematical problems, write music, walk through windows, and do murder in their sleep.可知一般来说梦游的人是在睡觉的时候，做一些奇怪的事情的人，选A【小题2】细节题：从文章第二段的句子：a hundred policemen searched for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there.可知一个男孩在自己的房间睡觉，但是在陌生的房间醒来。选C【小题3】细节题：从文章第三段的句子：a student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Lowa River.可知有个大学生养成了在午夜醒来，在河边散步的习惯，选B【小题4】推理题：从最后一段的句子：Many sleepwalkers do not try to find help and their sleepwalking is never recorded.可知为什么人们认为梦游只是一个没有解释的奇特的事情，因为大多数梦游者不会因为他们的问题寻求帮助。选D
