Advertising
Advertising is a form. of selling. For thousands of years there have been individuals who have tried to 51 others to buy the food they have produced or the goods they have made or the services they can 52
But in the 19th century the mass production of goods 53 the Industrial Revolution made person-to-person selling inefficient. The mass distribution of goods that 54 the development of the railway and highway made person-to-person selling too slow and expensive. At the same time mass communication first newspapers and magazines then radio and television made mass selling through 55 possible.
The objective of any advertisement is to convince people that it is in their best 56 to take the action the advertiser is recommending. The action 57 be to purchase a product, use a service, vote for a political candidate or even to join the Army.
Advertising as a 58 developed first and most rapidly in the United States country that uses it to the greatest 59 In 1980 advertising expenditures in the U.S exceeded 55 billion dollars or 60 2 percent of the gross national product. Canada spent about 1.2 percent of its gross national product 61 advertising.

Dreams
Of all the components of a good night&39;s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated this revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the
late 1970s, neurologists had switched to thinking of them as just "mental noise" -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind&39;s emotional thermostat, regulating moods while the brain is "off-line" . And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. "It&39;s your dream, " says Rosalind Cartwright, chair of psychology at Chicago&39;s Medical Center, "If you don&39;t like it, change it. "
Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement ) sleep --when most vivid dreams occur -- as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the "emotional brain" ) is especially active, while the prefrontal cortex (the center of intellect and reasoning ) is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day, " says Stanford sleep researcher Dr. William Dement.
The link between dreams and emotions shows up among the patients in Cartwright&39;s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don&39;t always think about the emotional significance of the day&39;s events -until, it appears, we begin to dream.
And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there&39;s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic, " Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people&39;s anxiety. Those suffering from persistent nightmares should seek
help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep—or rather dream -- on it and you&39;ll feel better in the morning.
