23、ing Comprehension 30 Much of the research on hallucinogenic drugs such as LSD has focused on the neurotransmitter serotonin, a chemical that when released from a presynaptic serotonin-secreting neuron causes the transmission of a nerve impulse across a synapse to an adjacent postsynaptic, or target,

24、 neuron. There are two major reasons for this emphasis. First, it was discovered early on that many of the major hallucinogens have a molecular structure similar to that of serotonin. In addition, animal studies of brain neurochemistry following administration of hallucinogens invariably reported ch

25、anges in serotonin levels. Early investigators correctly reasoned that the structural similarity to the serotonin molecule might imply that LSD s effects arc brought about by an action on the neurotransmission of serotonin in the brain. Unfortunately, the level of technical expertise in the field of

26、 brain research was such that this hypothesis had to be tested or, peripheral tissue ( tissue outside the brain). Two different groups of scientists reported than LSD powerfully blockaded serotonin s action, their conclusions were quickly challenged, however. We now know that the action of a drug at

27、 one site in the body does not necessarily correspond to the drug s action at another site, especially when one site is in the brain and the other is not. By the 1960 s technical advances permitted the direct testing of the hypothesis that LSD and related hallucinogens act by directly suppressing th

28、e activity of serotonin secreting neurons themselvesthe so called presynaptic hypothesis. Researchers reasoned that if the hallucinogenic drags act by suppressing the activity of serotonin-secreting neurons, then drugs administered after these neurons had been destroyed should have no effect on beha

29、vior, because the system would already be maximally suppressed. Contrary to their expectations, neuron destruction enhanced the effect of LSD and related hallucinogens on behavior. Thus hallucinogenic drugs apparently do not act directly on serotonin-secreting neurons. However, these and other avail

30、able data do support an alternative hypothesis, that LSD and related drugs act directly at receptor sites on serotonin target neurons (the postsynaptic hypothesis). The fact that LSD elicits “serotonin syndrome“, that is, causes the same kinds of behaviors as does the administration of serotonin in

31、animals whose brains are depleted of serotonin indicates that LSD acts directly on serotonin receptors, rather than indirectly through the release of stores of serotonin. The enhanced effect of LSD reported after serotonin depletion could be due to a proliferation of serotonin receptor sites on sero

32、tonin target neurons. This phenomenon often follows neuron destruction or neurotransmitter depletion; the increase in the number of receptor sites appears to be a compensatory response to decreased input. Significantly, this hypothesis is supported by number of different laboratories 31 According to

33、 the passage, which of the following is one of the primary factors that led researchers studying hallucinogenic drugs to focus on serotonin? （ A） The suppression of the activity of serotonin-secreting neurons by the administration of hallucinogens. （ B） The observed similarities in the chemical stru

34、ctures of serotonin and hallucinogens. （ C） The effects the administration of hallucinogens has on serotonin production in the human brain. （ D） Serotonin-induced changes in the effects of hallucinogens on behavior. 32 It can be inferred that researchers abandoned the presynaptic hypothesis because_

35、 . （ A） a new and more attractive hypothesis was suggested （ B） no research was reported that supported the hypothesis （ C） research results provided evidence to counter the hypothesis （ D） the hypothesis was supported only by studies of animals and not by studies of human beings 33 Which of the fol

36、lowing best expresses the main idea of ale passage? （ A） Research has suggested that the neurotransmitter serotonin is responsible for the effects of hallucinogenic drugs on the brain ant on behavior. （ B） Researchers have spent an inadequate amount of time developing theories concerning the way in

37、which the effects of hallucinogenic drags occur. （ C） Research results strongly suggest that hallucinogenic drugs create their effects by acting on the serotonin receptor sites located on target neurons in the brain. （ D） Researchers have recently made valuable discoveries concerning the effects of

38、depleting the amount of serotonin in the brain. 34 The research described in the passage is primarily concerned with answering which of the following questions? （ A） How can researchers control the effects that LSD has on behavior? （ B） How are animals reactions to LSD different from those human bei

39、ngs? （ C） What triggers the effects that LSD has on human behavior? （ D） What technical advances would permit researchers to predict more accurately the effects of LSD on behavior? 34 When we consider great painters of the past, the study of art and the study of illusion cannot always be separated.

40、By illusion I mean those contrivances of color, line, shape, and so forth that lead us to see marks on a flat surface as depicting three-dimensional objects in space. I must emphasize that I am not making a plea, disguised or otherwise, for the exercise of illusionist tricks in painting today, altho

41、ugh I am, in fact, rather critical of certain theories of non-representational art. But to argue over these theories would be to miss the point. That the discoveries and effects of representation that were the pride of earlier artists have become trivial today I would not deny for a moment. Yet I be

42、lieve that we are in real danger of losing contact with past masters if we accept the fashionable doctrine that such matters never had anything to do with art. The very reason why the representation of nature can now be considered something commonplace should be of the greatest interest to art histo

43、rians. Never before has there been an age when the visual image was so cheap in every sense of the word. We are surrounded and assailed by posters and advertisements, comics and magazine illustrations. We see aspects of reality represented on television, postage stamps, and food packages. Painting i

44、s taught in school and practiced as a pastime, and many modest amateurs have mastered tricks that would have looked like sheet magic to the fourteenth-century painter Giotto. Even the crude colored renderings on a cereal box might have made Giotto s contemporaries gasp. Perhaps there are people who

45、conclude from this that the cereal box is superior to a Giotto; I do not. But I think that the victory and vulgarization of representational skills create a problem for both art historians and critics. In this connection it is instructive to remember the Greek saying that to marvel is the beginning

46、of knowledge and if we cease to marvel we may be in danger of ceasing to know. I believe we must restore our sense of wonder at the capacity to conjure up by forms, lines, shades, or colors those mysterious phantoms of visual reality we call “pictures.“ Even comics and advertisements rightly viewed,

47、 provide food for though. Just as the study of poetry remains incomplete without an awareness of the language of prose, so, I believe, the study of art will be increasingly supplemented by inquiry into the “linguistics“ of the visual image. The way the language of art refers to the visible world is

48、both so obvious and so mysterious that it is still largely unknown except to artist who use it as we use all languagewithout needing to know its grammar and semantics. 35 The author of the passage explicitly disagrees with which of the following statements? （ A） In modem society even nonartists can

49、master techniques that great artists of the fourteenth century did not employ. （ B） The ability to represent a three-dimensional object on a flat surface has nothing to do with art. （ C） In modem society the victory of representational skills has created a problem for art critics. （ D） The way that artists are able to represent the visible world is an area that needs a great de
