There have been rumors. Theres been gossip. All Hollywood is shocked to learn that Calista Flockhart, star of Foxs hit TV show Ally McBeal, is so thin. And we in the media are falling all over ourselves trying to figure out whether Flockhart has an eating disorder, especially now that she has denied it. Well, Im not playing the game. If the entertainment industry really cared about sending the wrong message on body image, it wouldnt need so many slender celebrities in the first place.

But the fact remains that 2 million Americansmost of them women and girlsdo suffer from eating disorders. In the most extreme cases they literally starve themselves to death. And those who survive are at greater risk of developing brittle bones, life-threatening infections, kidney damage and heart problems. Fortunately, doctors have learned a lot over the past decade about what causes eating disorders and how to treat them.

The numbers are shocking. Approximately 1 in 150 teenage girls in the U. S. falls victim to anorexia nervosa, broadly defined as the refusal to eat enough to maintain even a minimal body weight. Not so clear is how many more suffer from bulimia, in which they binge on food, eating perhaps two or three days worth of meals in 30 minutes, then remove the excess by taking medicine to move the bowels or inducing vomiting. Nor does age necessarily protect you. Anorexia has been diagnosed in girls as young as eight. Most deaths from the condition occur in women over 45.

Doctors used to think eating disorders were purely psychological. Now they realize theres some problematic biology as well. In a study published in the Archives of General Psychiatry recently, researchers found abnormal levels of serotonin, a neurotransmitter in the brain, in women who had been free of bulimia for at least a year. That may help explain why drugs have allowed a lot of people to stop swallowing in large doses of food. Unfortunately, the pills dont work as well for denial of food. Nor do they offer a simple one-stop cure. Health-care workers must re-educate their patients in how to eat and think about food.

How can you tell if someone you love has an eating disorder? Bulimics will often leave evidence around as if they want to get caught. Says Tamara Pryor, director of an eating-disorders clinic at the University of Kansas in Wichita. Anorexics, by contrast, are more likely to go through long periods of denial.

[A] the media has mislead the publics view of celebrities

[B] there is much misunderstanding about eating disorders

[C] body image concerns are an indication of eating disorders

下列能体现阴阳互根互用的是

A.阳根于阴,阴根于阳
B.阴生于阳,阳生于阴
C.孤阴不生,孤阳不长
D.阴在内,阳之守也;阳在外,阴之使也
答案:A,B,C,D
解析:
此题考查的是阴阳的互根互用内涵。阴阳的互根互用是指事物或现象中相互对立的阴阳两个方面,具有相互依存、相互为用的关系。“阴根于阳,阳根于阴”是指相互对立的阴阳双方,又相互依存、相互化生、相互为用。“阴生于阳,阳生于阴”是指阴阳互根互用,相互依存,各以对方的存在为自己存在的前提。从人体来说,阳气所代表的功能产生,必须依附于阴所代表的精血等物质为基础。阴精所代表的功能产生,必须依附于阳气为基础。“孤阴不生,孤阳不长”是说阳依附于阴,阴依附于阳,在它们之间,存在着相互滋生、相互依存的关系,即任何阳的一面或阴的一面,都不能离开另一面而单独存在。“阴在内,阳之守也;阳在外,阴之使也”是说阴在内而为阳之镇守,阳在外而为阴之使役。二者具有相互依存,相互为用的关系,体现了阴阳的互根互用。选项ABCD都体现了阴阳互根互用,说明阴和阳是相互依存、相互为用的关系,所以答案是ABCD。
