问题     A few years ago an American campaigner wrote a book in which he set the main points of his fascinating crusade(改革运动)-to abolish television. His book Four Arguments for the Elimination of Television is an American cult(狂热崇拜的)bestseller, and after eight editions is still generating concern and savage debate(热烈的讨论)in the USA.
    JerryMander, a former advertising expert is convinced that for the sake of our freedom, and mental and physical health, we should learn to live without TV. Through his advertising background Mander is aware of how much of television is concerned with advertising. He sees the planting of values for profit as "a deep, profound and disturbing act by the few against the many, for a trivial purpose". And, even without commercials, he sees TV as disturbing because it crams people’s heads with images, which alter the way they feel and behave. Pictures formed by 300, 000 tiny dancing dots altering 30 times per second, bombard(轰击)their eyes as people scan the images 10 times a second. The brain registers stores all 30 images, but the conscious mind registers far fewer. But, argues Mander, even if you reject or doubt what you see consciously, it is too late, the crucial(极其重要的)messages have gone home.
    He further argues that TV is deadening experience as it is restricted to just two senses—sight and sound. " Perception(感觉，感知)is dulled and flattened, "says Mander, "when you can’t feel and smell and totally experience an event. "People are just sitting passively for up to four hours a night watching a flickering screen and listening to artificial sound. " No culture in history has spent such an enormous amount of time looking at artificial light, " says Mander, " and another worrying fact is that prolonged exposure to artificial light alters human cells, which is why it is being used for certain medical treatment. " Researchers do not know if lifelong TV exposure is a physical risk or not, but as Mander Would argue, why run the risk ? It is important that people get up now and switch off before the harm is done—they might also become brainwashed, or, who knows, they might even be approaching death.
Mander thinks people’s feelings and behaviour are changed because( ).
