单选题 There have been rumors. There's been gossip. All Hollywood is shocked to learn that Calista Flockhart, star of Fox's 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, I'm not playing the game. If the entertainment industry really cared about sending the wrong message on body image, it wouldn't need so many slender celebrities in the first place.
But the fact remains that 2 million Americans—most of them women and girls—do suffer from eating disorders. In the most extreme cases they literally starve themselves to death. And those who survive are at a 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 there's 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 don't work as well for denial of food. Nor do they offer a simple one-step 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? "Bulimies 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.

单选题 We can infer from the first paragraph that ______.
A. the media has misled the public's view of celebrities
B. there is much misunderstanding about eating disorders
C. body image concerns are an indication of eating disorders
D. the entertainment industry is combating eating disorders

【正确答案】 C

【答案解析】本题为引申推理题。第一段列举了一位好莱坞明星的例子，指出由于该明星过分消瘦，引起公众怀疑她患有饮食性疾病。由此可推出公众的怀疑是因为该明星对身体形象的过分关注，故可推知正确答案为C“对身体形象的关注是饮食性疾患的标志。”该段尾句用虚拟语气指出，“如果娱乐业真的担心在身体形象上传达错误的信息……”。言外之意是娱乐业在一定程度上误导了人们有关身体形象的看法，故可排除D项，A项错在celebrity。B项文中未提及故无从推知，所以正确答案为C。

单选题 The victims of eating disorders, more often than not, will ______.
A. starve themselves to death
B. suffer greatly from the complications
C. puzzle doctors in the years to come
D. recover completely with no aftereffects

【正确答案】 B

【答案解析】本题为细节题。仔细阅读第二段可知该段主要论述了饮食性疾患的危害及治疗情况。由本段第三句“And those who survive are at a greater risk of developing brittle bones, life threatening infections，kidney damage and heart problems”可知，饮食性疾病的幸存者，患各种其他疾病的危险更大，由此可知B项正确。而D项可完全康复不留后遗症的表述与事实不符，可排除。A项中的starve themselves to death虽是该段第二句的原词再现，但注意第二句句首的in the most extreme cases，故可排除A项；由末句可知，医生已经掌握了大量关于饮食性疾患及治疗的信息，排除C项。

单选题 The word "binge" (Line 3, Paragraph 3) most probably means "______" .
A. eat excessively B. refuse to eat
C. fail to digest D. enjoy a good appetite

单选题 Bulimia is found to be ______.
A. related to the level of serotonin
B. psychological rather than biological
C. identical with anorexia nervosa in the cure
D. a leading cause of death among middle-aged women

【正确答案】 A

【答案解析】本题为细节题。由第四段的第三、四句“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”可知，复合胺有助于让许多人停止吞食大量的食物，即摆脱暴食症，因此A项正确。由该段首句可知饮食性疾患(包括暴食症)也是生理问题，故可排除B项。再由该段的第五句可知(治疗暴食症的)药物对于治疗厌食不起作用，故C项排除。第三段末句提到，厌食症造成的死亡大多发生在45岁以上的妇女身上，而D项所说的暴食症是中年妇女死亡的主要原因文中并未提及，故不可选。
