Although most dreams apparently happen spontaneously, dream activity maybe provoked by external influences. "Suffocation" dreams are connected with the breathing difficulties of a heavy cold, for instance. Internal disorders such as indigestion can cause vivid dreams, and dreams of racing fire-engines may be caused by the ringing of an alarm bell.
Experiments have been carried out to investigate the connection between deliberately inflicted pain and dreaming. For example, a sleeper pricked with a pin perhaps dreams of fighing a battle and receiving a severe sword wounD．Although the dream is stimulated by the physical discomfort, the actual events of the dream depend on the associations of the discomfort in the mind of the sleeper.
A dreamer's eyes often move rapidly from side to side. Since people born blind do not dream visually and do not manifest this eye activity, it is thought that the dreamer may be scanning the scene depicted in his dream. A certain amount of dreaming seems to be a human requirement-if a sleeper is roused every time his eyes begin to move fast, effectively depriving him of his dreams, he will make more eye movements the following night.
People differ greatly in their claims to dreaming. Some say they dream every night, others only very occasionally, individual differences probably exist, but some people immediately forget dreams and others have good recall.
Superstition and magical practices thrive on the supposed power of dreams to foretell the future. Instances of dreams which have later turned out to be prophetic have often been recorded, some by men of the highest intellectual integrity. Although it is better to keep an open mind on the subject, it is true that the alleged power of dreams to predict future events still remains unproveD．
Everyone knows that a sleeping dog often behaves as though he were dreaming, but it is impossible to tell what his whines and twitches really mean. By analogy with human experience, however, it is reasonable to suppose that at least the higher animals are capable of dreaming.
Of the many theories of dreams, Freud's is probably the best known. According to Freud, we revert in our dreams to the modes of thought characteristic of early childhooD．Our thinking becomes concrete, pictorial and non-logic, and expresses ideas and wishes we are no longer conscious of. Dreams are absurd and unaccountable because out conscious mind, not willing to acknowledge our subconscious ideas, disguises them. Some of Freud's interpretations are extremely fanciful, but there is almost certainly some truth in his view that dreams express the subconscious mind．
According to the passage, the dream world has the qualifies of being______.
We can conclude from the passage that______.
In an uncritical August 11, 1997, World News Tonight report on "diamagnetic therapy," a physical therapist explained that "magnets are another form. of electric energy that we now think has a powerful effect on bodies." A fellow selling $ 89 magnets proclaimed: "All humans are magnetic. Every cell has a positive and negative side of it."
On the positive side, these magnets are so weak that they cause no harm. On the negative side, these magnets do have the remarkable power of attracting the pocketbooks of gullible Americans to the tune of about $ 300 million a year. They range in scale from coin- sized patches to mattresses, and their curative powers are said to be nearly limitless, based on the premise that magnetic fields increase blood circulation and enrich oxygen supplies because of the iron pressure in the blood.
This is fantastic flapdoodle and a financial flimflam. Iron atoms in a magnet are crammed together in a solid state about one atom apart from one another. In your blood only four iron atoms are allocated to each hemoglobin molecule, and they are separated by distances too great to form. a magnet. This is easily rested by picking your finger and placing a drop of your blood next to a magnet.
What about claims that magnets attenuate pain？ In a 1997 Baylor College of Medicine double-blind study of 50 patients (in which 29 got real magnets and 21 got sham ones), 76 percent in the experimental group but just 19 percent in the control group reported a reduction in pain. Unfortunately, this study included only one 45-minute treatment, did not try other pain-reduction modalities, did not record the length of the pain reduction and has never been replicated.
Scientists studying magnetic therapy would do well to read the 1784 "Report of the Commissioners Charged by the King to Examine Animal Magnetism" (reprinted in an English translation in Skeptic, Vol. 4, No. 3). The report was instituted by French King Louis XVI and conducted by Benjamin Franklin and Antoine Lavoisier to experimentally test the claims of German physician Franz Anton Mesmer, discoverer of "animal magnetism." Mesmer reasoned that just as an invisible force of magnetism draws iron shavings to a lodestone, so does an invisible force of animal magnetism flow through living beings.
What does the passage mainly talk about？
Edgar Snow was a reporter and a joumalist. He was a doer, a seeker of facts. His mature years were spent in communicating to people-he was an opener of minds, a bright pair of eyes on what went on about him. Fortunately, he went to many places, knew many people, saw many things; thus he communicated from depth and involvement. Suspicious of dogma, he stated in his autobiography. "What interested me was chiefly people, all kinds of people, and what they thought and said and how they lived-rather than officials, and what they said in their interviews and handouts about whatthey people' thought and saiD．" In writing about people and the event which shaped or misshaped their lives, his point of view was essentially honest and searching- founded on his own inquiry and resting on a body of truth perceived with vision and with compassion. His valued friend and editor, Mary Heathcote, stated that to Edgar Snow, "true professionalism meant telling the truth as one saw it, with as many of the reasons for its existence as one could find out and as much empathy as possible for the people experiencing it..."
That he is remembered mostly through Red Star Over China is understandable. The accounts in that book were of international importance and the experience for the author in getting those accounts was perhaps the most significant one in his life. Though it is typical of him what, after the acclaim the book received, he commented, "I simply wrote down that I was told by the extraordinary young men and women with whom it was my privilege to live at age thirty, and from whom I learned a great deal. " That "great deal" spread from the pages of Red Star to alter the thinking of countless people—including many citizens of China who were led by it to action that drastically affected their own lives and the course of their country's future. An awesome realization of personal responsibility also came about at this point for the young journalist, one he was cognizant of the rest of his life—the discovery, as he heard of friends and students killed in a war they had been moved to join largely because of his reports, that his writing had taken on the nature of political action and that he, as a writer, had to be personally answerable for all he wrote.
There were other texts which broke through ignorance and prejudice in similar ways: Far Eastern Front, Living China, Battle for Asia, People on Our Side, Journey To the Beginning, to name some of the eleven books he produced, as well as many pages of engaged reporting—of floods and famines, of wars declared and undeclared, of human dilemmas and indignities, of unsung heroes and unheralded sacrifices-a life's study of the impact of people and events from many lands known at first hanD．
Ed represents what is best in American joumalism—as did his compatriot Agnes Smedley and Jack Belden. They dedicated to action, to communication that would help lessen the need, help correct the injustices. A main objective of theirs, because they were there and they saw, because they were internationalists with concern for human welfare, values and dignity, was to contribute to an understanding of China and the crippling burdens she bore—in a world dominated by arrogance, greed, and ignorance.
According to the article, the writings of Edgar Snow were based on______.
