样认识董其昌的“南北宗”论.
参考答案：
南北宗论的创立者想通过从唐至明近千年的山水画的分析总结，用艺术风格分流派，并加以褒贬，以建立绘画的新风格和绘画批评的新标准.竭力抬高文人画，贬底南北朝以上的院体画和青绿山水画体系.南北宗论有片面性只用两个流派去归纳，难免有自相矛盾，牵强附会，评价白当之处.
应该肯定董其昌做出的贡献.南北宗论是文人画思潮的一种反映，所以一经建立，便得到文人画家的赞同.此论树立了温和文雅、精气内含的作风，鉴定了文人画在绘画史上的主导地位.
| With the understanding of phobias has come a magic bag of treatments: exposure therapy that can stomp out a lifetime phobia in a single six-hour session; virtual-reality programs that can safely simulate the thing the phobia most fears, slowly stripping it of its power to terrorize; new medications that can snuff the brain’s phobic spark before it can catch. In the past year, the U. S. Food and Drug Administration approved the first drug—an existing antidepressant. Most psychologists now assign phobias to one of the three broad categories: social phobias, in which the sufferer feels paralyzing fear at the prospect of social or professional encounters; panic disorders, in which the person is periodically blindsided by overwhelming fear for no apparent reason; and specific phobias—fear of snakes and enclosed spaces and heights and the like. If you are living with a generalized sense of danger, it can be profoundly therapeutic to find a single object on which to deposit all that unformed fear—a snake, a spider and a rat. A specific phobia becomes a sort of backfire for fear, a controlled blaze that prevents other blazes from catching. But a condition that is so easy to pick up is becoming almost as easy to shake, usually without resort to drugs. What turns up the wattage of a phobia the most is the strategy the phobias rely on to ease their discomfort: avoidance. The harder phobics work to avoid the things they fear, the more the brain grows convinced that the threat is real. Progress in treating social-anxiety disorder is also providing hope for the last—and most disabling—of the family of phobias: panic disorder. Panic disorder is to anxiety conditions what a tornado is to weather conditions: a devastating sneaks havoc and then simply vanishes. Unlike the specific phobic and the social phobic who know what will trigger their fear, the victim of panic attacks never know where or when one will hit. Someone who experiences an attack in, say, a supermarket will often not return there, associating the once neutral place with the traumatic event. But the perceived circle of safety can quickly shrink, until sufferers may be confined entirely to their homes. When this begins to happen, panic disorder mutates into full-blown agoraphobia. The treatment for agoraphobia is much the same as it is for social phobia: cognitive-behavioral therapy and drugs. |
